ABSTRACT:
Apparatus for inspecting a solid-state image pickup device comprises: a memory for saving an image data from the solid-state image pickup device; an arithmetic operation part that performs predetermined image processing on the image data saved in the memory and outputting an evaluation value; and a controller that judges whether the solid-state image pickup device is good based on the evaluation value. The arithmetic operation part adds image data values saved in the memory in the column direction (extension direction of a vertical charge transfer path) to obtain a column-based addition value. The arithmetic operation part then obtains difference data from the adjacent value, counts the number of difference data items contained in the plurality of specified level regions, and obtains the evaluation value based on the sum total of the products of level information and count in the level regions.
