Canon develops 120MP digital camera

Written by Nick Farell


13280x9184 pixels
Boffins working for Canon have developed a digital camera sensor with a 120-megapixel resolution.

Dubbed the APS-H sensor can manage 13,280 x 9,184 pixels and the CMOS sensor is so densely packed with pixels that it can capture full HD video on just one-sixtieth of the total surface area. Normally processing such high resolution images would cause a camera to have a major headache. But Canon claims it would be possible to shoot 9.5 frames per second with the new sensor "by modifying the method employed to control the readout circuit timing".

It seems unlikely that a camera could buffer such high resolution images in its memory using today's technology. Currently the best a DSLR camera can manage is the 16-megapixel sensor found in the 1D. This is not the first time that Canon has shown off a high megapixel sensor. The outfit showed off a 50-megapixel CMOS sensor in 2007, but that has yet to see the light of day.

Quoting Haberlandt:
9.5 frames per second?



A very fast processor and a large amount of ram or a very fast SSD will be required to catch up with the speed of the sensor, especially for 120MP RAW format files.

A standard RAW format 12MP file is about 15MB. If we say 120MP RAW file is 120MB, we get:

9.5 x 120MB = 1140MB/s

There is no such SSD this fast, which works with battery power. They might need to add i-RAM alike drives which would skyrocket the costs.

technology pushes further.. but the rest of the parts have to catch up to make use of it. Still they could always make a "downgraded" version of it that can improve what is available today hopefully.
