Abstract:
1. An image processing apparatus which processes an image signal, comprising: an image sensing element having a plurality of photoelectric conversion units each corresponding to a plurality of pixels outputting image signals and dark signals, the dark signals being signals output from the pixels in the dark; a determining unit which determines whether a dark level of an image signal from one of the plurality of pixels is higher than a predetermined level; a first correction unit which corrects the image signal from the one of the plurality of pixels using image signals from other pixels, when the dark level of the image signal from the one of the plurality of pixels is higher than the predetermined level; a second correction unit which corrects the image signal from the one of the plurality of pixels, by subtracting the dark signal from the image signal, when the dark level of the image signal from the one of the plurality of pixels is equal to or lower than the predetermined level; and a controller which selectively changes the predetermined level in accordance with information that pertains to image sensing.
