INTRODUCTION Digital camera:

utilizes high speed optical networks.transfers super high definition (SHD) images.

Current transfer services offer high definition (HD) quality video.

An extra high quality 8k format enables a realistic telepresence.

Combined with special tools such as video editing systems.

Realizes effective remote collaboration for business work spaces.

WORKING OF 8K-IMAGING SYSTEM

Developed for use in next generation TV broadcasting systems.

Two methods of 8k camera systems : a) Four Sensor Imaging Method .

b) Three 33-MPIXEL image sensors.

10

A.)FOUR SENSOR IMAGING METHOD

Meets the practical demands for the prototype camera systems.

To obtain high resolution and high quality pictures uses:

two image sensors for sensing green light.

one sensor for red light.one for blue light.

11

• INCIDENT LIGHT IS SEPARATED INTO FOUR COLOUR AND DIVIDED IN TO….• TWO GREEN, ONE RED, AND ONE BLUE (GGRB).• THREE-SENSOR IMAGING SYSTEM (RGB) USED IN COMMERCIAL AND BROADCAST VIDEO CAMERAS.• PRISM FOR THE FOUR-SENSOR SYSTEM CAN BE MADE AS SMALL AS THE CONVENTIONAL RGB PRISM.

PRACTICAL 8K CAMERA WITH FOUR-SENSOR IMAGE SYSTEM

12

13

FOUR SENSOR METHOD

Relatively high sensitivity. Maintains a high dynamic

range. Reduces the cost of sensors

to a great extent. Increases transfer capacity. Widens the dynamic range. Improves the blooming

characteristics.

Increases the power consumption.

Increases the size of the camera by the use of more than one sensor.

ADVANTAGES DISADVANTAGES

14

B.) THREE 33-MPIXEL CMOS IMAGE SENSOR

Consumes relatively more power. Has a high volume of signal processing devices. Configuration is divided into the camera head

and CCU(camera control unit). The camera head has:

image sensors.head boards for driving the sensors.a signal transmission interface for

transmitting data to the CPU.

SECURITY AND MONITORING

ISSUE: face recognition in a crowd at airports, train stations and

during mass events (e.g. stadiums)

Many details on single 8K frame – the powerful source for image

processing

Useful for police, border services and others security units

Constraints:

scalability,

processing

VISUALISATION OF SCIENTIFIC PROCESSES

High resolution images in science:Physicis – visualisation of research on elementary particles and quantum mechanicsBiochemistry – particles and chemical reactions visualisation, genetics structures visualisationMeteorology – visualisation of complex weather processes as well as disasters (e.g. tornados, earthquakes)Astronomy and radioastronomy – presentations of sky maps, stars and planets

CONCLUSION

Development of the SHD imaging system: replacement of film cinema with digital camera.

Digital cinema: will utilize movie content delivery via optical networks soon.

needs only bulk file transfer.

ODS: utilizes the networks for real time data transfer.

One way streaming.

A need to reduce the transmission latency while preserving 8k/2k flexibility and stability.
