It is an object of the present invention to provide a video processing apparatus which can perform separately two shading corrections including a dark shading correction of an image and a peripheral shading correction for light falloff at edges of the image, and can calculate, with accuracy, correction gains corresponding to respective pixels from the correction values of blocks. The video processing apparatus comprises an imaging element 2 for producing an image of an object, a correction value storage unit 5c having stored therein correction values of blocks each of which forms part of the image produced by the imaging element 2, a correction gain interpolating unit 5d for calculating a correction gain of a designated pixel of the imaging element 2 by performing an interpolation on the basis of correction values corresponding to blocks which are in the vicinity of the designated pixel, a dark shading correction unit for performing a dark shading correction of the image on the basis of the correction gain calculated by the correction gain interpolating unit 5d, and a peripheral shading correction unit 5f for performing a peripheral shading correction for light falloff at edges of the image on the basis of the correction gain calculated by the correction gain interpolating unit 5d.
