PROBLEM TO BE SOLVED: To correct ununiformity among a plurality of imaging regions in real time by taking into account even temperature variations of an imaging device or around the imaging device. 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 thermometer 121 for measuring a temperature of the imaging device or around the imaging device; 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 detection of the output level detection means and a result of the temperature measurement by the thermometer 121, 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.
