Canon announces two new 250MP industrial sensors
Canon announced two new industrial sensors that they will add to their product line of sensors. They are curious ones, sporting high resolution. One is color, the other monochrome. Canon.. good idea now do this for a camera please.
In essence, all this technology is already used in Canon's sensors. ROI is something we certainly want in a high MP EOS-R camera so we can do APS-C at a higher speed than the rest of the sensor. But I suspect this is already done on the 4K crops in even the last generation of sensors from Canon. 1.25 billion pixels per second is also a been there, done that with the EOS R5 reading out 900 million pixels per second from a larger sensor (larger sensors are harder because they have more resistance, thus more heat, noise,etc) in stills and 2.6 billion pixels in oversampled HQ 4K. Yeah, that's 2.6 billion folks. Even with ROI that's 2 billion pixels per second. The sensor has to do DPAF which is another sensor readout. So probably double those numbers to get to reality. Wonder how come it overheats?
The "thinning" is basically line skipping. Been there done that too. This sensor also isn't DPAF. A further demonstration that it's simply not for Canon's cameras.
So what does this mean for all of us waiting for an R5s? Not much really. But I'll be curious to see the datasheet and what equipment they made it on, it may give us further clues to what equipment Canon is now using. Why APS-H? No, Canon isn't going to make an APS-H camera - usually, Canon does these sensors to perfect technologies and APS-H is the largest sensor they can make using one pass with a stepper. To make it bigger they either have to use different equipment or stitch the sensor together, at a greater cost.
I know it sounds impressive, it is from the aspect that they can pack that many pixels on a sensor (around 650MP for a full-frame sensor) but other than that, the R5 sensor is a modern marvel, and as far as I'm concerned one of the most impressive sensors by any manufacturer.
There's also a video (shown below)
From Canon (machine translated)
As a new product of APS-H size (about 29.4 x 18.9 mm) CMOS sensor, Canon will release “LI8020SAC (color) / LI8020SAM (monochrome)” capable of imaging about 250 million pixels (19,568 x 12,588 pixels) in 2020. It will be released in late October of the year.
The new product is an ultra-high resolution CMOS sensor with approximately 250 million pixels, which enables you to capture detailed information in an image while shooting a wide range. In addition, by setting the pitch of one pixel to 1.5 μm (micrometer), we have achieved approximately 250 million pixels in APS-H size, making it possible to use it for various purposes. It can be used for various purposes such as FPD (flat panel display) inspection, which has become higher definition due to the development of 4K / 8K video technology, industrial inspection, video production, digital archive, wide-area surveillance, microscope, etc. Meet the needs of users.
Get detailed information even in a wide range of shooting with ultra-high resolution of about 250 million pixels
The new product is capable of imaging at an ultra-high resolution of about 250 million pixels, which is about 125 times that of Full HD (1,920 x 1,080 pixels) and about 30 times that of 4K (3,840 x 2,160 pixels), and can be taken in any shooting range. Sufficient resolution can be obtained by trimming the area and enlarging it with electronic zoom.
Achieves ultra-high-speed signal reading of approximately 1.25 billion pixels/second
With CMOS sensors, the amount of signal increases as the number of pixels increases, causing signal delays and slight timing deviations. The new product has an ultra-multi-pixel structure of approximately 250 million pixels, but by refining the circuit and advancing signal processing technology, it has achieved an ultra-high-speed signal reading of approximately 1.25 billion pixels per second. This enables ultra-high resolution imaging at a speed of approximately 5 frames/sec even when all pixels are readout.
Supports data output according to user needs with “ROI read function” etc.
The new product is equipped with an “ROI (Region of Interest) read function” that selectively reads only an arbitrary area. If you want to read only a specific area at high speed, you can use the “ROI read function” at 24 fps for 8K (7,680 x 4,320 pixels), 30 fps for 4K (3,840 x 2,160), and 60 fps for full HD (1,920 x 1,080). Video recording is possible. It also has a “thinning out reading function * ” that thins out the entire image area in the vertical direction to read out, so you can select the data output method that suits your needs.
