Abstract

PURPOSE: To effectively utilize an image memory by decreasing the quantity of recorded information in a mode not to require the resolution of an image by changing the compressibility of image data corresponding to the degree of changing an added state.
CONSTITUTION: A diaphragm part 2 executes diaphragm value control driven by a driving circuit 9 to be controlled by a control signal from a system controller (CPU) 8. In this case, the image of an object is converted to the electric signals of plural picture elements and outputted by an image pickup means. A, when the quantity of light from a flash light emitter 11 is deficient in the case photographing while using the flash light emitter 11, an adding means B adds the electric signals of the plural picture elements outputted from the image pickup means A, and an added state changing means C changes the added state corresponding to the degree of deficiency of the quantity of light. Then, a compressibility changing means D changes the compressibility of the image data in the case of recording to the image memory corresponding to the degree of changing the added state.
