Abstract
CMOS image sensor with a rolling shutter that uses two separate clocks. One of the clocks is used during normal operation. When timing is changed, the other clock is started and used during an interim period to avoid distortion in the image. After that interim period, the new clock timing is coupled to the original clock circuit.
