Canon explores large image sensors for academic and industrial application

Canon

Canon posted a technical article about the company’s efforts in researching large size image sensors. The sensor in the article below is 40 times the size of a 35mm CMOS sensor. Nothing you will see on Canon’s next mirrorless camera.

The Potential to Open New Frontiers in Academic and Industrial FieldsCMOS Image Sensors

In addition to the image sensors used in its consumer-model digital cameras, Canon is exploring new potential in academic fields and industrial fields through the development of ultrahigh-sensitivity CMOS image sensors and ultrahigh-resolution CMOS image sensors.

The World’s Largest Ultrahigh-Sensitivity CMOS Image Sensor

A certain level of light is required when shooting with a digital camera or camcorder, and without it, images cannot be captured due to insufficient sensitivity.

In the pursuit of further improving the sensitivity of imaging elements, Canon has embraced the challenge of achieving higher levels of sensitivity and larger element sizes while maintaining high-speed readout performance, and has succeeded in developing the world’s largest class of CMOS image sensor measuring approximately 20 cm square. At present, the standard diameter of the silicon wafers on which CMOS sensors are fabricated is 12 inches (approx. 30 cm). As such, a 20-cm-square sensor is the largest size that can be manufactured based on these dimensions, and is equivalent to nearly 40 times the size of a 35 mm full-frame CMOS sensor.

Increasing the size of CMOS sensors entails overcoming such problems as distortion and transmission delays for the electrical signals converted from light. To resolve these issues, Canon not only made use of a parallel processing circuit, but also exercised ingenuity with the transfer method itself. As a result, the sensor makes possible the shooting of video at 60 frames per second with only 0.3 lux of illumination (approximately the same level of brightness as that generated by a full moon).

120-Megapixel Ultrahigh-Resolution CMOS Image Sensor

Canon has spent many years working to reduce the pixel size for CMOS image sensors. These efforts have led to astounding results, making possible a pixel size of 2.2 µm for a total of approximately 120 million pixels on a single sensor. The APS-H size (approx. 29 x 20 mm) CMOS sensor boasts approximately 7.5 times the number of pixels and 2.6 times the resolution of sensors of the same size featured in existing products.

This CMOS sensor performs parallel processing to support the high-speed readout of large volumes of pixels, and by modifying the method employed to control the readout circuit timing, Canon successfully achieved the high-speed readout of sensor signals. As a result, the sensor makes possible a maximum output speed of approximately 9.5 frames per second, supporting the continuous shooting of ultrahigh-resolution images.

Images captured with the ultrahigh-resolution CMOS sensor maintain high levels of definition and clarity even when cropped or digitally magnified. Accordingly, this sensor offers potential for a range of industrial applications, including cameras for shooting images for large-format poster prints, cameras for the image inspection of precision parts, aerospace cameras, and omnidirectional vision cameras.

The 120-megapixel ultrahigh-resolution performance of the Canon CMOS sensor may lead to unprecedented industrial applications that could only be imagined in the past.

Canon enters sensor business, three high performance sensors on sale, 120MP inclusive

Canon

Three of Canon’s most advanced and specialised sensors are on sale to the public. This is no surprise as it was reported to be part of Canon’s plans back in 2016.

The sensors are a 120 Megapixel CMOS Sensor, a 5 Megapixel Global Shutter CMOS, and the 35MMFHDXS, 19μm Full HD CMOS Sensor. If you’re curious to learn more click here. In the past we reported extensively about these sensors.

The sensors can be purchased through Canon’s own authorized distributor Phase 1 Technology Corp.

Canon industrial sensors redefine high-performance with state-of-the-art technology, backed by decades of ongoing development and improvement. Featuring the 120 Megapixel CMOS sensor, the 5 Megapixel Global Shutter CMOS sensor, and the 35MMFHDXS CMOS sensor, Phase 1 Technology offers Canon’s most advanced industrial sensors.

For OEMs, solutions providers, vision integrators and others in search of advanced machine vision components, Canon’s powerful industrial sensors are equipped for a wide range of applications.

These kind of sensor gets used in surveillance tech, medical applications, and other specialised domains. Below you see some videos highlighting Canon’s sensors technology and performance.

The original Canon EOS M can shoot 2.5K raw video with Magic Lantern, and it’s impressing

Canon Eos M

Warning: the sd_uhs module referenced below is currently highly experimental and can destroy your sd card or camera. There have been instances of sd cards breaking. Magic Lantern does not recommend its use at the moment because of the risk involved.

I’m reporting this because Magic Lantern‘s work deserves it, and because I’m an old school hacker and can’t help getting excited by stuff like this. Computer science was made by this sort of guys, not by fancy dudes like Apple’s or the likes. I’ve been there since the beginning and I am pretty sure to understand the value of what these skilled hackers are doing.

So, here is another amazing hack by the Magic Lantern team, showcased by Synth & Sundry in the video below. It’s truly impressing: a Magic Lantern SD UHS overclock hack test on a the first Canon EOS M (2013). Shot at 2520×1080, 5x zoom mode, 24 fps, 12 bit lossless compressed raw using sd_uhs module. Not bad, eh?

It may be true that Canon cripples their tech when they want it, but still, this code hacking proofs what Canon’s sensor tech can deliver. Even on the so much disgraced original Canon EOS M (which I still proudly own and never will get rid off).

Again: do not try this if you don’t exactly know what you are doing. This is experimental stuff and it may seriously harm your camera, I do not encourage you to try to apply this hack.

Kudos Magic Lantern for the hacking! If you dare and want to know more, have a look at Magic Lantern’s download page.



We covered Magic Lantern’s work, and they have a forum where you can learn more.
