Filed: 2000-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating solid-state image pickup element with which charge transfer faults can be detected with high accuracy, without erroneously recognizing a white line as a charge transfer fault. SOLUTION: After the output levels a-h of each R pixel and G pixel in a RED row in the vertical transfer direction are detected, by irradiating solid-state image pickup elements in a Bayer arrangement with RED light, the difference (a-b), (c-d) (e-f) and (g-h) between the output levels of the R pixel and succeeding G pixel are calculated. Consequently, the output component W of the white which is the object of erroneous detection is eliminated. In addition, the differences (a-b), etc., between the output levels of the R pixel and succeeding G pixel are added vertically to each other for, for example, with 100 lines in the vertical transfer direction, and the added results are compared with each other. Thus only the output component T of a charge transfer fault in the RED row is detected easily, without erroneously evaluating the white line as a charge transfer fault.
