TOKYO, October 19, 2020—Canon Inc. and Canon Marketing Japan Inc. announced today the launch in Japan of the LI8020SAC (color) and LI8020SAM (monochrome), two new APS-H size (approximately 29.4 mm x 18.9 mm) CMOS sensors capable of image capture with a resolution of approximately 250 megapixels (19,568 x 12,588 pixels).

The new CMOS sensors achieve an ultra-high-resolution of approximately 250 megapixels, enabling the image capture of wide areas while also preserving fine details throughout the image. With a pixel pitch of 1.5 μm (micrometers), a total of approximately 250 million pixels can be accommodated on an APS-H size sensor, making the sensors suitable for a wide variety of applications. From inspections of flat-panel displays (FPD), which continue to require increased precision due to the growth of 4K and 8K technology, to industrial inspections, video productions and digital archiving, wide-area monitoring and microscopes, the potential uses for the new sensors help meet a wide range of user needs.

The LI8020SAC and LI8020SAM realize image capture with an ultra-high-resolution of 250 megapixels—approximately 125 times that of full HD (1920 x 1080 pixels) and approximately 30 times that of 4K (3840 x 2160 pixels)—allowing users to crop selected areas and digitally zoom to expand images while still retaining sufficiently high resolution.

As CMOS sensors increase in pixel count, the amount of signal also increases, leading to such problems as signal delay and slight discrepancies in timing. However, the new sensors, while delivering an incredibly high pixel count of approximately 250 million, features miniaturized circuitry and enhanced signal processing technology to achieve an ultra-high pixel readout speed of approximately 1,250 megapixels per second. This enables the sensors to realize ultra-high resolution image capture at up to approximately 5 frames per second (FPS), even during full pixel readout.

The LI8020SAC and LI8020SAM feature an ROI (Region of Interest) function, which allows users to an arbitrary region to read from the sensor, reducing the amount of read information and allowing for image capture at an increased framerate. Using this function, 8K (7680 x 4320 pixels) video can be captured at 24 fps, 4K (3840 x 2160 pixels) at 30 fps and full HD (1920 x 1080 pixels) at 60 fps. What’s more, the sensors also include a Sub-sampling Readout* function that enables users to omit vertical sections of the image area and output data in various ways according to their needs.

* Sub-sampling is available in four patterns: 1/3 (approx. 15 fps), 1/5 (approx. 25 fps), 1/7 (approx. 35 fps) and 1/9 (approx. 45fps).
