METHOD FOR CORRECTING SENSITIVITY OF IMAGE SENSOR

摘要

PURPOSE:To read a picture image with low cost and high quality by using an output of another element near one element to correct the object element output in reading. CONSTITUTION:An output of each element is measured by giving a prescribed incident light to each element of an image sensor comprising plural elements outputting an output in response to the intensity of the incident light. The picture image of high quality is read by applying the correction of sensitivity to a few elements (n) having remarkably high or low sensitivity or not showing a normal function while referencing outputs of adjacent elements n-1, n+1.
