New Canon CMOS Sensor Eliminates Rolling Shutter

With the simultaneous rise of CMOS sensors and fast frame rate video in DSLRs, the issue of rolling shutter has become a big concern. Canon has developed a new CMOS sensor with “global shutter” that may eliminate the effect of the rolling shutter in future DSLRs.

The rolling shutter effect is used to describe distortion in fast moving subject caused by the way CMOS sensors captures pixels—one row at a time. The CCD sensor is more expensive – less ideal for consumer DSLRs – but is able to capture all pixels at once with a “global shutter.”

If Canon can implement a CMOS sensor with global shutter, it will be a welcome change, especially for videographers shooting at high frame rate 4K. DPReview.com has found a pretty significant rolling shutter effect in the new 5D Mark IV.



According to Canon, the new sensor “exposes all of the sensor’s pixels at the same time, [enabling] the capture of distortion-free images even when shooting fast-moving objects.”

No word on when we will see this sensor used in consumer cameras, but Canon does say it will prioritize cameras used for major television or film productions. These sensors will also debut for industrial uses where measurement of elements in a distortion-free frame is key.
