Abstract
An image processing apparatus includes: an image sensor outputting at least long and short accumulation images with longer and shorter exposure times, respectively, in one field; first and second long accumulation evaluation value computation units computing first and second long accumulation evaluation values from the long accumulation image; a short accumulation evaluation value computation unit computing a short accumulation evaluation value from the short accumulation image; a short accumulation exposure control unit acquiring a short accumulation target exposure time and short accumulation exposure control information from the short accumulation evaluation value and a first target level; a long accumulation evaluation value synthesis unit acquiring a long accumulation evaluation value by synthesizing the first long accumulation evaluation value and the second long accumulation evaluation value; a long accumulation exposure control unit acquiring long accumulation exposure control information from the long accumulation evaluation value and a second target level; and a synthesis unit generating one image from the long accumulation image and the short accumulation image.
