HIGH-SPEED EVENT IMAGING DEVICE

摘要

A high−speed event is imaged with an image sensor (7) comprising an optical sensor circuit having a logarithmic characteristic, provided with initializing means for suppressing occurrence of an after image, and used for each pixel unit. The data on the image produced by the image sensor (7) is stored in a memory (20). The variation of each pixel output of the image sensor (7) is corrected on the basis of the data on the image read out of the memory (20) by a corrector (18). An image is displayed on a display (22) on the basis of the corrected data. While storing data at a speed following up the high−speed event, the variation of each pixel output of the image sensor is corrected at a normal processing speed without following up the high speed.
