PROBLEM TO BE SOLVED: To cope with even dynamic variations such as temperature or secular variations by correcting the ununiformity between a plurality of imaging regions in real time. SOLUTION: The correction apparatus is provided with: a plurality of level adjustment means 113, 114 for respectively independently adjusting a level of a plurality of imaging signals outputted from a plurality of output terminals; an output level detection means 116 for detecting an output level of a plurality of the level adjustment means; a focal degree discrimination means 117 for discriminating a focal degree of an imaging optical system of an imaging element; and a correction coefficient decision means 117 for deciding a correction coefficient to decrease a level difference of each imaging signal on the basis of a result of the detection of the output level detection means 116 and a result of the focal degree discrimination by the microcomputer 117, and the correction coefficient decision means 117 gives the decided correction coefficient to the level adjustment means 113, 114 so as to decreasingly adjust the level differences of each imaging signal.
