Canon trumpets the APS-H-size sensor as having the world’s largest number of pixels for a CMOS sensor smaller than 35mm full-frame.
It hopes the technology can be used in surveillance cameras and other industrial equipment.
In a statement, Canon said: ‘With CMOS sensors, increases in pixel counts result in increased signal volume, which can cause such problems as signal delays and slight discrepancies in timing.
‘The new Canon-developed CMOS sensor, however, despite its exceptionally high pixel count, achieves an ultra-high signal readout speed of 1.25 billion pixels per second, made possible through such advancements as circuit miniaturisation and enhanced signal-processing technology.
‘Accordingly, the sensor enables the capture of ultra-high-pixel-count video at a speed of five frames per second.’
Canon claims the sensor combines high sensitivity with low noise.
It added: ‘The exceptionally high definition made possible by the sensor lets users crop and magnify video images without sacrificing image resolution and clarity.’
