An image sensing device of this invention corrects sensitivity nonuniformity of an image sensing element. This image sensing device has an image sensing element ( 5 ) having a two-dimensional matrix of pixels, a first multiplier circuit ( 18 ) for multiplying the output from the image sensing element ( 5 ) output via an A/D converter ( 7 ) by horizontal linear correction data, a second multiplier circuit ( 19 ) for multiplying the product of the first multiplier circuit by vertical linear correction data, a selector ( 16 ) for selecting horizontal linear correction data, and a selector ( 17 ) for selecting vertical linear correction data. The device switches the selectors ( 16, 17 ) in accordance with the position (horizontal and vertical addresses) of the pixel of interest.
