Canon is showing off a 120mp CMOS sensor this week at CP+, which they talked about back in 2010. While the sensor isn’t said to be for photography, it is interesting nonetheless. You can see an image of it compared to the brand new 50.6mp (53mp total) sensor that will appear in Canon’s EOS 5Ds and EOS 5Ds R DSLRs.
The frame rate of read-out for this ultra high-resolution is 9.5fps, and is made possible by reading multiple pixels simultaneously at high speeds – a process Canon is calling ‘parallel signal processing’. The 120 million pixels – of 2.2 µm pixel pitch – are contained on a sensor 29.2mm x 20.2mm in size, yielding pixel dimensions of 13280×9184.
