PROBLEM TO BE SOLVED: To correct inclination of an image signal toward a high luminance side and to obtain an appropriate output picture by allowing the signal conversion means to have conversion characteristics for a high luminance image where a rising part shifts toward the high luminance side of an input level rather than reference conversion characteristics for ordinary photographing at the time of flash photographing at a short distance. SOLUTION: In a signal processing circuit 313, prescribed signal processing is applied to an image signal obtained from a CCD 303 and level adjustment of the image signal is performed by gain adjustment of an AGC circuit inside. In an A/D converter 205, each pixel signal of the image signal to be obtained from the signal processing circuit 313 is converted into a digital signal. In aγcorrection circuit 208, there are pluralγcorrection tables of different characteristics andγcharacteristics of the image signal are corrected. In the case of short distance flash photographing mode, theγcorrection table for high luminance image is selected. When a bit length of an output signal has aγcorrection circuit smaller than that of an input signal, it becomes particularly effective to perform high luminance correction in theγcorrection circuit.
