Canon’s 250MP APS-H sensor is based on column parallel ADC technology

canon 250mp sensor

Do you remember the 250MP sensor Canon showed off last year? I am pretty sure the sensor is based on column parallel ADC technology.

There is an interesting paper presented at ISSCC 2016 (2016 IEEE international Solid-State Circuits Conference) by a team of Canon researchers, with title (thanks Richard)

An APS-H-Size 250Mpixel CMOS Image Sensor Using Column Single-Slope ADCs with Dual-Gain Amplifiers” (H. Totsuka, T. Tsuboi, T. Muto, D. Yoshida, Y. Matsuno, M. Ohmura, H. Takahashi, K. Sakurai, T. Ichikawa, H. Yuzurihara, S. Inoue -Canon, Kawasaki, Japan)

Unfortunately the paper will be presented in January, when the conference takes place, and is not yet available to the public.

I posted a few days ago that Canon filed a slew of patents regarding column parallel ADC technology, and that I got a hint this technology may be implemented in future Canon pro bodies (which in the meantime has been reposted by some sites). I am currently studying more Canon patents that all refer to column parallel ADC technology. Given the sheer amount of such patent, I think it is safe to assume that Canon has some plans with this technology.

2016 will be an exciting year for Canon, with new pro bodies coming (EOS 5D Mark IV and EOS-1D X Mark II) along with the EOS 6D Mark II and possibly a full-frame mirrorless camera. It’s too early to speculate on which cameras Canon will feature a sensor with column parallel ADC technology, but they will. I believe we may see this technology first on the EOS 5D Mark IV and EOS-1D X Mark II.

The video below (by Fotografiapuntoit) gives an overview on Canon’s 250MP sensor. Stay tuned for more…

New sensor technology coming to future Canon pro bodies (EOS-1D X Mark II)?

I got some hints that Canon may implement a new sensor technology in their future pro-level DSLRs. The Canon EOS-1D X Mark II was also mentioned to possibly get a new sensor tech.

Thanks to reader Richard, we know that there is a slew of patents referring to column parallel sensors, a technology Sony is using on their EXMOR sensors. Quoting one of Canon’s patent applications, a column-parallel A/D converter is…:

a method for improving precision in analog-digital conversion […] of pixel signals. The A/D converter includes a first A/D converter (first processing unit) and a second A/D converter (second processing unit), and the first processing unit performs A/D conversion to generate higher-order bits of digital signals and then the second processing unit performs A/D conversion to generate lower-order bits. The first processing unit performs the first A/D conversion by comparing an analog signal to be converted and a reference voltage. The second processing unit starts charging a capacitor by a constant current source according to the result of the comparison performed by the first processing unit, and ends the charging in response to an edge of a clock signal (a rising edge) supplied immediately thereafter. Then, the second processing unit maintains the voltage for the capacitor and performs the second A/D conversion.

According to information passed over to me, Canon filed not less than seven (7) patents referring to column parallel sensor technology. A bit too much to believe Canon does not have some (big?) plans with such a sensor technology. Therefore, suggestions stating the Canon EOS-1D X may feature a new technology sensor may point in the right direction.

One of the patents is US2015/0341577. It refers to a column parallel sensor, and it seems to describe a method to get more dynamic range from shadows.

I am currently studying the other patents and will disclose them soon. Stay tuned…
