Canon has developed a new 1” backside illuminated sensor that is capable of capturing 24.6 stops of dynamic range in 4K, according to the manufacturer. For comparison, most modern cameras claim to have 12-15 stops of dynamic range with the ARRI ALEXA 35 claiming 17 stops. The human eye is said to have only 21 stops of dynamic range. Let’s take a look at how Canon was able to achieve these impressive results. The engineers at Canon always seem to dazzle us with eye-catching headlines — like back in 2015 when they announced a low-light sensor capable of 4 Million ISO. Even though this new sensor is intended primarily for monitoring applications, perhaps this is a glimpse of what is to come. New 1-inch backside illuminated sensor from Canon. Image credit: Canon Global Canon has developed a 1.0-inch, backside illuminated CMOS sensor, that breaks new ground in delivering more than 24 stops of dynamic range in 4K resolution at 30fps. To do this, the engineers developed a new approach that divides the sensor into 736 areas and determines the best exposure settings for each one. Conventional ultra-HDR example. Image credit: Tobias Bjørkli Conventional ultra-HDR methods rely on taking multiple exposures and synthesizing them into a single image, usually in camera. That technique can produce motion artefacts and blurring when dealing with moving objects. The method Canon has developed to deal with this problem allows each of the 736 regions of the sensor to be exposed independently to the optimal exposure...
