Apparatus for color imager defect determination

An inspection apparatus for inspecting a color solid-state image pickup element, comprising:

• A/D conversion means for converting from analog to a digital form image signals outputted by the color solid-state image pickup element;
• an image memory for storing as image data the image signals which have been A/D converted by said A/D conversion means;
• storage means for storing as a table numerical hue data which represent the degree of color unevenness between an actual object and a stored image which is generally recognized by the human eye as a perceived color, said numerical hue data being a numeric representation of a hue difference between a fault portion of color unevenness and a normal color portion, as perceived by a normal human eye, this hue difference weighting the length of a difference vector used in determining the presence of a fault in the image pickup element;
• calculation means for performing image processing on the basis of said image data stored in said image memory, and which calculates judgment parameters on the basis of these image calculation results and said numerical hue data stored in said storage means;
• and
• judgment means for judging whether a color solid-state image pickup element is faulty or not, on the basis of said judgment parameters.
