Up until now, Canon has sold the G series and S series cameras with the highest level of image quality in the industry. Amongst high-end users there is widespread acknowledgement that Canon means quality images. However, we also saw lots of comments from users wondering when a “dream compact camera” with the CMOS sensor found on Canon’s digital SLR cameras would come about. As a development team we wanted to respond and we were able to implement it in the development this time around.

How was it decided to equip the camera with a large format sensor?

This plan was actually being considered from the time of the PowerShot G12 development. We felt however that the technology was not of the quality that we would be happy to offer to our customers. As a result, we believe that although the G1 X is a long-awaited camera, it’s one that we can be proud of.

In order to achieve a pixel size equivalent to a DSLR, a large type version of the APS-C size CMOS sensor used in the EOS 7D, 60D, and EOS 600D was produced. The 4:3 aspect ratio was decided upon, with consideration made for striking a balance between the camera size and the most suitable image quality performance.

This sensor was developed specifically for the G1 X, it was not simply a case of reusing an existing EOS sensor.

Performance areas such as sensitivity, S/N and dynamic range are of the same level as EOS, but as the size was reduced, the required specs were stricter than with an SLR. It was developed with a strong awareness of inheriting EOS technology, and priority on pixel size and sensitivity. Pixel size in particular was an important factor in planning the performance. The size was decided upon taking elements such as the body size, lens specs, and signal processing into account.

How was the sensor size decided?

Results and merits of using a large type sensor

Background blur approx. 2.6 times greater than with a 1/1.7 type sensor can be expressed at the same focal length and f-numbers. We have already carried out surveys with professional photographers, which indicate that they experienced shallow depth of field previously thought impossible in a compact camera.

Another area of improvement is the high sensitivity. As a result of enlarging the cell pitch, high sensitivity ISO 12800 can now be used without a problem. Shooting is now possible not just in dark locations, but in almost total darkness. It can also take advantage of the maximum 1/4000 sec. shutter speed, allowing successful shooting of sports in an indoor gymnasium. Essentially this camera has expanded the realm of what is possible, allowing the capture of scenes that you simply would have given up on before, from bright daylight to pitch darkness.

Shooting shallow depth of field with background blurring on a par with SLR cameras was difficult with existing compact cameras. Now it’s possible.

Regarding the resolution, MTF (modular transfer function) was improved by enlarging the sensor size. The range of tuning has also expanded as a result of the reduced noise. Emphasised edges have made output settings possible to bring out image clarity. In surveys carried out with professional photographers, their evaluation was that it was on par with SLR, and I would definitely like you to experience the unsurpassed noise reduction quality, in other words the “high level of image clarity”, and the “clarity due to low noise”.

Does enlarging the sensor also improve the level of image clarity?

Is there an effect on image quality and diffraction phenomenon at small apertures?The cell pitch was enlarged to 4 microns, and as the iris diameter can be larger, there is less chance of diffraction phenomenon influence at small apertures.

Not only photos with a shallow depth of field, but also photos with a small aperture can also be portrayed sharply with clarity. As a matter of fact, the smallest aperture on the G12 was f/8, however, it is possible to shoot with up to f/16 on the G1 X. From portrait photography utilising background blurring, to shooting landscapes that are sharp into the distance, you can enjoy free control of the depth of field.

DIGIC 5 uses approximately four times as much information as before to resolve one pixel.

As the ultimate PowerShot, we wanted to achieve epoch-making image quality with ISO 12800 at any cost.

We believe that for what we call the HS System, two technologies are necessary, the sensor capability, and a high performance image processor to draw this out. DIGIC 5 uses approximately four times as much information as before to resolve one pixel. A six times faster processing speed achieves a significant acceleration of processing times. For the total performance of noise and image clarity, this has an effect of two stops at high ISOs compared to the G12, and three stops at lower ISOs. As the G1 X’s sensor is 14-bit, we can expect even higher quality images. Even at the same high ISOs, Canon’s colour reproduction is overwhelming. By fully drawing out the power of the large format sensor and high performance processor on the G1 X, colour information at high ISOs is consistently preserved, and even the details are sufficiently expressed, making it possible to portray beautiful photographs.

Does the aim of image processing differ from EOS?

From the point of image processing, Canon has shared ideas so they are basically the same, with a slight technical difference. As opposed to the natural image processing on DSLR cameras where the desire to retouch is high, for compact camera image processing, impressions straight from the camera are important, and therefore image processing is a little bit sharper. The G1 X can shoot RAW images at 14-bit, so it is possible to process the images however you like after shooting.

11

What are some distinct benefits from shooting with 14-bit RAW?

What kind of scenes are suitable for 14-bit RAW?

By upgrading RAW to 14-bit, it makes it possible to preserve even more information in RAW images. By effectively utilizing this information, improved image quality of various correction processes such as image clarity of minute texture, better noise reduction capability, expanded dynamic range, and shadow correction are achieved.

Compared to existing compact cameras, RAW on the G1 X records more information with less noise. This means it has even better potential for retouching. For evening scenes in which exposure control can be difficult, and saturation control of landscapes for example, we believe that customers who actively retouch and create images will be more than satisfied. With DPP (Digital Photo Professional), the application of noise reduction, level of edge emphasis etc. can be minutely controlled, making it possible to create images similar to an EOS. This makes it possible to obtain the output you want, in line with your own preferences.

How well does it meet high image quality movie needs?

The G1 X takes advantage of background blur* approaching that of SLRs, and you can shoot high image quality movies with rich expression. We believe there is great demand for this from advanced amateurs and users that shoot creative works, such as portrait movies, movies that have a shallow depth of field, and blurry backgrounds in particular.

By exhaustively pursuing image quality in movies as well as stills, it is now possible to clearly shoot high image quality movies taking advantage of high resolution, with expressive depth of field and low noise.

LENS DESIGNER MANAGER,

Lens Products Development Centre, Image Communication Products OperationsMakoto SekitaSekita is a lens design specialist who made a major contribution to the development of the first-generation DIGITAL IXUS and its legendary one-yen-coin lens. His craftsmanship is at the root of the G1 X development.

A UA lens this big is comparable to the maximum diameter class.

14

What development ideals are shared across all Canon lenses?Each lens differs depending on sensor size, so they cannot be compared on the same stage. A standard of reliability applies however, whether they are EF lenses for an SLR, or lenses for a compact camera. They are all created with the same quality standards. This time in particular, even when compared to EF lenses, there is absolutely no loss of precision due to it being larger, as it uses a large negative meniscus UA lens of the maximum diameter class. This means development is equivalent to compact lenses with equal or greater precision.

Incidentally, with compact cameras there is a technique not used with EF lenses. The top and bottom portion of the lens not necessary for imaging is cut off, this technique is called a D-cut, and I-cut. By cutting lenses that have been enlarged, they make effective use of the space.

A UA lens this big is comparable to the maximum diameter class.

15

What is a UA lens, and what are its advantages?UA stands for ultra high refractive index aspherical lens. It is a glass-moulded aspherical lens with an ultra high refractive index developed by Canon, and contributes significantly to size reduction and higher camera performance. Glass moulding technology allows the manufacture of metallic moulds which maintain high precision, even when glass softens under elevated temperatures. This is crucial to the production of UA lenses. In addition to this large-diameter UA lens, the G1 X uses a total of three glass-moulded lenses.

Glass moulding technology allows the manufacture of metallic moulds which maintain high precision, even when glass softens under elevated temperatures.

Features and construction of the lenses

Lens construction of the G1 X lens is roughly divided into four units. Three aspheric lenses are distributed in the back three units, and they correct aberration. Performance for the entire range of the zoom including the middle area is improved. The main role of aberration correction by each unit is to correct aberration at the wide-end with the UA lens of the second unit, to correct aberration at the telephoto-end with the third unit near the iris, and to correct aberration while adjusting focus with the fourth unit.

Put simply, if the size or role of the aspheric lenses differs, the degree of difficulty in development will differ for each one. An experiment like this does not really have any precedents with EF lenses, meaning it was quite a challenge.

Hiroshi SaruwatariSaruwatari is in charge of overall lens design in all compact digital camera products. Some of his most representative works include the IXUS 300 HS and PowerShot A700.

Even though the lens was enlarged by approximately 2.5 times, a compact design with a lens diameter of approximately 1.4 times larger was achieved.

18

The balance between the sensor and the camera body size decided it. As the G1 X uses a particularly large format sensor, assessing where to place the balance between size and lens specifications was difficult. With consideration for usability, we believed that the wide-angle 28mm could not be eliminated. However, regarding the same zoom ratio as the 5x zoom on the G12, as the body size would become bigger no matter what, the zoom was stopped at 4x.

Design of a 5x zoom is not technically impossible, but it was decided that

How was the focal length and zoom magnification decided?

it would not be desirable to pursue specs that would sacrifice body size and usability, both of which a compact camera cannot do without.

The lens was enlarged, and even though the sensor size is approximately 2.5 times larger than the existing G12, the lens remains at approximately 1.4 times larger. An optical 4x zoom at this size is quite small; it is about the size of the fixed focal length lens on mirrorless SLR cameras. The reason for this is the merit of matching the optics with the sensor for an integrated lens that could be optimised.

High performance stimulates the spark of imagination. The range of photographic expression will broaden dramatically.

At Canon, how is the G series positioned as a camera?The G series is a sophisticated compact series at the peak of the high end of image quality, aimed at advanced amateurs who usually enjoy shooting with SLR cameras. It is a camera that has both portability and high image quality, and pro photographers can hide it in the pocket of their camera bag. The G was extremely popular as a compact that could take great photos at a time when digital SLRs were still expensive and not widespread. Mainly in the U.S. and Europe, there were many professionals who used it for work. Even though SLRs are now in widespread use, the current PowerShot G12 is still

highly valued by pro photographers in the U.S. and in Europe. This time, with the implementation of the large format sensor in particular, we have achieved image quality of a different dimension. Because of this, the new G1 X is not a genuine successor to the G12, it was developed as a solution for high- end users who demand even higher image quality. The G1 X has the appeal of total balance, to be used powerfully by customers.

I hope that lots of users will enjoy using this camera.

21

What concepts have been inherited from the first-generation G series?“Compact with the best image quality” is the mission of the G series. Always in pursuit of the best quality, providing an index to all compact cameras, image quality has been pursued. With the G1 X in particular, we aimed for a camera that would make you feel like you could take great photos when you picked it up, and would make you happy just operating it.

As an EOS sub-model, compatibility with EOS accessories is an important mission component for the G1 X.

Although EF flashes are not synchronized, various adjustments to the flash can be made on the camera. Additionally, by choosing “EOS Style” in the menu, EOS users can also naturally use the dial control system on the front and back of the camera. Filters, such as PL filters, can be used via a separately sold filter adapter (58 mm dia.).

We always want to offer great results to users that want to challenge manual operations and with a wide array of accessories, it’s possible to shoot even better photos.

G1 (2000) G7 (2006)

The appeal of the G is the total balance of image quality and portability.

22

When did development of the G1 X begin?The actual idea has been around for a few years. We wanted to create a compact camera equipped with a large format sensor on par with an SLR. Discussions ensued, and it has finally come together as a finished product. Digital SLR cameras are now widespread, and customers have become more knowledgeable about photos. With the aim of the ultimate image quality, it was discussed whether the G should continue with the existing sensor, and the decision was made to equip it with a large format sensor.

However, when speaking of image quality, it is not always the case that interchangeable lens types are the best, and optimisation of the optic design into an integrated lens type has its merits. Despite the fact that it is equipped with a large format sensor, as it is integrated, even at this size we were able to equip it with a 4x zoom lens.

The appeal of the G is the total balance of image quality and portability.

23

Who are the target users?We would really like advanced amateurs who have SLR camera experience to use the G1 X. They can experience an abundance of camera functions and various photographic expressions by applying SLR techniques they already have.

As most customers enjoy shooting with the camera customised to their liking, we are very excited to see how they enjoy using this camera. It is also targeted at professionals, press-related users and journalists have a particular requirement for portability and silence.

As the lens, sensor, and image processor used in the G1 X are all manufactured by Canon, this means the optic design is the best it can be.

24

So, what are the appeal points?We are confident in the outstanding noise reduction performance that exceeds that of compact cameras up until now, as well as the high image quality, and the background blurring provided by the large format sensor. Without the superior lens, sensor, and image processor, the image quality would not be this high.

The more the sensor size is enlarged, the greater the corresponding difference in image processor performance will be. As the lens, sensor, and image processor used in the G1 X are all manufactured by Canon, this means the optic design is the best it can be.

DEVELOPER

The AF function was adjusted for the large format sensor. As a result of the larger sensor size, the stroke of the focus lens, or distance for focusing with the same amount of focus, is longer. However, as the lens is larger and heavier it is more difficult to move. As a result, the motor and screw were improved for faster, more accurate lens control. In order to maintain the same high level of usability as the G-series has had up until now, out-of-sight design efforts were made. When AF is added, reduced sensor noise means improved AF performance. We are proud

that the detection performance of face recognition works even in darkness. Though they are not visible in the spec figures, we believed it was important to focus attention on these details and advances.

Also, touching on the shutter unit, durability is more than double that of the G12. Full size, high-speed continuous shooting at 4.5 fps is possible on the G1 X, as the number of times the shutter opens and closes rapidly increases. It was therefore necessary to maintain durability for worry-free use.

27

Are there any points where EOS users were acknowledged during the design process?The rear dial is characteristic of operability on the EOS. I believe EOS users can use it naturally. This is also the first time Canon has used a 920,000 dot LCD monitor on a compact camera. It is the same one being used on the EOS 600D. It is an IPS type with a wide viewing angle, making it easy to see when shooting with the vari-angle screen, a merit that increases the styles of shooting.

It is not limited to this model, and as there is particular emphasis on the LCD monitor’s visibility, this is one of the most beautiful top-ranking LCDs.

There is a high level of compatibility with existing EOS accessories, including flashes.

First of all, around a dozen candidates within the design department contributed design sketches. The designer was chosen from these entries. The G series has been very popular within the company from the start, not only with designers. I think this is because it is the most creative and challenging camera to date. Up until now, I had led the design of many IXUS and A series cameras, but as this was my first time in charge of such an auspicious model, I really felt challenged.

How did the design project start out?

I think the clear-cut design with unnecessary waste removed, and bare functional beauty looks stylish.

DESIGN

31

What is the design concept, what did you aim for?

I was aiming for a simple, “professional’s tool” with no waste, and bare functionality. Since the PowerShot G7, the controls had been getting more complex, and I wanted to organise them, so I went after simple looks with functional beauty. This time around the lens and sensor have changed dramatically, so it was a challenge to give the impression of change with just a quick glance. The concept I pursued was one of authenticity, I wanted a camera that a professional would be proud to have among their equipment.

32

After deciding on the image, what process did you go through to complete the mock-up?The next process was to create a 3D model and finalise the design details. The methods of making 3D models differ from person to person. Some use styrofoam or balsa wood, and create by carving out the form, other people create the design in 3D form on a computer from the start. 3D printers are now absolutely necessary. This blue material is made from resin, and by reading in the CG data, the machine automatically models the form. Models like this are used to create a mock-up for finalising the actual operability etc. Mock-ups are individually hand-made by artisans, they are extremely expensive, and take a long time to create. Because of this, models are used to check details before production of the mock-up. In this fashion, even after many design improvements in the process, it is still redone several times when problems arise during the design stage. This is especially true for a camera like the G with its extreme peculiarities.

The transition from model to mock-up

The concept I pursued was one of authenticity, I wanted a camera that a professional would be proud to have among their equipment.

33

What textures and coatings were used for this flagship model?

Metal was used not only for the front cover, but the rear cover as well for a sense of luxury. When held in the hand, we wanted users to experience the cool metallic feel, and the solidity. This is probably the first time metal parts have been used on the rear cover of a camera with a vari-angle LCD. Plastic is easy to process, but it lacks a feeling of luxury so we really wanted to go with metal. This is a minor point, but there is a top cover which hides the front and rear cover seams when viewed from above.

F-1 Front and rear covers made from metal

Detailed processing like this work toward improving the visual impression.

Furthermore, up until now a rough beaded coating had been used to coat the surface. This time the metal was coated directly, which emphasises surface texture of the linear form. The surface texture was modelled after the past classic “F-1” camera. Classic with a modern impression, this design is aimed at being amenable to a wide range of ages.

Classic with a modern impression, this design is aimed at being amenable to a wide range of ages.

34

Is there emphasis on any other design details?There are design processes everywhere to make it look as refined as possible. Bevelling the top surface of the body housing for example, is one way of making the body look slimmer and smaller.

Also, on cameras with a vari-angle LCD there is usually a panel section like an overhang included to prevent rattling when closed. This time the method of keeping it closed was altered, so there is no overhang for a cleaner rear surface.

Parts for consideration

Adding a lattice-shaped twill line around the protruding lens enhances the ‘feel’ of the camera. Several patterns of textures and designs were considered in pursuit of an easy-grip finish.

The parts used in the G1 X consist almost entirely of new parts, so there are almost no shared parts from the G12.
