An image capture device and method for correcting output levels thereof, made up of an image shifter for moving an image position on a light receiving surface, having a differential calculating section for calculating the differential between the output levels of pixels receiving light from the same part of an image on a light-receiving surface before and after moving the image position; an offset amount calculating section for calculating the amount of offset to the output levels of pixels in a pixel line by sequentially adding the differences in output levels in pixel lines arrayed in the direction of image position movement; and a correcting section for correcting pixel output levels by equalizing the variability in output levels between pixels in a pixel line based on the amount of pixel offset in the pixel line.
