An image processing device for performing image processing for an image signal output from an image sensor, including: a preprocessing circuit for generating a correction signal based on the image signal from the image sensor; a signal processing circuit for correcting the image signal using the correction signal and converting the corrected signal to a luminance signal and a color-difference signal; and a control block. The control block performs either first processing in which the signal processing circuit uses the correction signal generated based on an image of a frame preceding the frame of an image currently supplied to the signal processing circuit, or second processing in which the image signal obtained from the image sensor is stored in an external memory, the stored image is read and supplied to the signal processing circuit, and the signal processing circuit uses the correction signal generated based on the image of the same frame as the supplied image.
