Canon develops record-setting 250Mpixel sensor

September 10, 2015 // By Peter Clarke
Canon has developed an image sensor array with the highest number of pixels in a CMOS sensor smaller than the size of a 35 mm full-frame sensor, the company has claimed.

The array of 19,580 by 12,600 pixels is contained on a CMOS chip measuring 29.2mm by 20.2mm. Such is the resolution of the sensor that it is able to distinguish lettering on the side of an airplane flying at a distance of approximately 18km.

This may give an indication of the applications of the sensor which is likely to in military and security cameras, measuring instruments and industrial uses and for still images rather than video.

The readout speed of the image sensor array is 1.25 billion pixels per second, made possible through such advancements as circuit miniaturization and enhanced signal-processing technology. This readout speed, although high, only allows video capture at five frames per second.

The image resolution is 125 times that of full HD (1,920 x 1,080 pixels) video and approximately 30 times that of 4K (3,840 x 2,160 pixels) video.

No indication was given if Canon intends to supply the sensor to the market or at what price. A prototype camera containing the sensor behind a 35mm F/1.4 lens has been shown.
