Today announces that its parent company, Canon Inc., is developing an APS-H-size approx. 29.2 x 20.2 mm CMOS sensor incorporating approximately 250 million pixels 19,580 x 12,600 pixels, the worlds highest number of pixels for a CMOS sensor smaller than the size of a 35 mm full-frame sensor.
When installed in a camera, the newly developed sensor was able to capture images enabling the distinguishing of lettering on the side of an airplane flying at a distance of approximately 18 km 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 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. Additionally, despite the exceptionally high pixel count, Canon applied its sensor technologies cultivated over many years to realise an architecture adapted for miniaturised pixels that delivers high-sensitivity, low-noise imaging performance.
Video footage captured by the camera outfitted with the approximately 250-megapixel CMOS sensor achieved a level of resolution that was approximately 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. The exceptionally high definition made possible by the sensor lets users crop and magnify video images without sacrificing image resolution and clarity.
Canon is considering the application of this technology in specialised surveillance and crime prevention tools, ultra-high-resolution measuring instruments and other industrial equipment, and the field of visual expression.
As of September 7, 2015, based on a Canon survey.
Image capture employed a combination of optical and digital zooming while distinguishing of image content was realised through the magnification of an approximately 1/40,000th-sized area of the captured image.
