IMAGE PROCESSING DEVICE USING DIFFERENCE CAMERA

摘要

A fast and stable image processing system detecting a mark from a differential image is described. The system includes a display displaying a first image and a second image alternately. A camera captures the first image that contains a mark and the second image. An image processing device detects the mark from a non-zero pixel region of a difference image between the first image that is captured and the second image that is captured.
