Abstract
A purpose of this invention is to execute proper smear correction corresponding to the image sensing purpose or condition without degrading the image quality. To achieve this purpose, the smear line signal of an image sensing signal output from a solid-state image sensing element (4) is stored in a smear line memory (7). The value of the smear line signal is limited by a limiting circuit (8), and smear correction is performed for the image sensing signal on the basis of the limited value.
