Canon Introduces Global Shutter Cmos Sensor With Improved Dynamic Range


Canon introduces global shutter CMOS sensor with improved dynamic rangeCanon has announced a global shutter CMOS sensor with a re-designed pixel structure aimed at boosting dynamic range. Using global shutter presents a clear benefit for the sensor's videography applications, as it doesn't suffer from the distortion effects that a standard 'progressive scan' sensor does when capturing fast-moving subjects.

However, global shutter designs have tended to offer less dynamic range than their conventional counterparts. Canon says that the sensor's drive system (the way it's read out) increases the amount of light the sensor can capture before overexposing. This is combined with a more efficient pixel structure and 'optimized internal configuration' to reduce noise and increase sensitivity. The result should be improved dynamic range, though it's not clear how this improved performance will compare with traditional chips of the kind that exhibit rolling shutter.

Canon says it will explore use of the chip in measurement and industrial applications, and consider applications in video production. No details of the sensor's size or resolution were given.
