Image processing device and camera

An image processing device for performing image processing for an image signal output from an image sensor and outputting the processed signal, comprising:

• a preprocessing circuit for generating a correction signal for correcting an image signal obtained from the image sensor based on the image signal and outputting the correction signal;
• a signal processing circuit for correcting an image signal obtained from the image sensor using the correction signal, converting the corrected signal to a luminance signal and a color-difference signal, and outputting the results;
• and
• a control block being selectively operable in a first processing mode or a second processing mode, the control block performing first processing in which the signal processing circuit uses the correction signal generated based on an image of a frame preceding a frame of an image currently supplied to the signal processing circuit in the first processing mode, and second processing in which an image signal obtained from the image sensor is stored in a memory provided outside the image processing device, 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 in the second processing mode.
