Canon has developed a 2/3″ sensor with a global shutter and high dynamic range, helping to pave the way toward future generations of video cameras.
The rolling shutter is a common issue in video. Because most cameras read each frame of sensor data by scanning across the frame either vertically or horizontally, this means that data from the sensor is not read simultaneously, which can cause artifacts, particularly with quickly moving subjects, the most common example being airplane propellers.
While certain cameras such as the Sony F55 have a global shutter, which reads all sensor data at the same time, the majority still use rolling shutters. Canon’s global shutter CMOS sensor initially had a smaller dynamic range that required two improvements to regain a wider range.
