Canon CMOS sensor wows with 250Mpx

Canon developed an APS-H-size CMOS sensor featuring 250Mpx (19,580px x 12,600px), which the company claims is the highest pixel count among image sensing devices worldwide.

When installed in a camera, the 29.2mm x 20.2mm sensor was able to capture images enabling the distinguishing of lettering on the side of an airplane flying at a distance of 18km from the shooting location.

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 CMOS sensor, however, achieves a high signal readout speed of 1.25 billion pixels/s.

It also enables ultra-high-definition video with a speed of 5fps. Canon has cultivated its sensor technologies for many years to realise the architecture for miniaturised pixels, delivering high-sensitivity, low-noise imaging performance.

Video footage captured by the camera outfitted with the approximately 250Mpx CMOS sensor achieved a level of resolution that was approximately 125 times that of Full HD (1,920px x 1,080px) video and approximately 30 times that of 4K (3,840px x 2,160px) video. The high definition made possible by the sensor lets users crop and magnify video images without sacrificing image resolution and clarity.

The Canon sensor is seen for use in specialised surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and photography.
