Title: Digital camera and recording medium
Inventor: TANAKA TOSHIYUKI
IPC: H04N5/243
Filed: 1999-03-19
Abstract: 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 a γcorrection circuit 208, there are plural γ correction tables of different characteristics and γ characteristics of the image signal are corrected. In the case of short distance flash photographing mode, the γ correction table for high luminance image is selected. When a bit length of an output signal has a γ correction circuit smaller than that of an input signal, it becomes particularly effective to perform high luminance correction in the γcorrection circuit.
