PROBLEM TO BE SOLVED: To eliminate a flicker due to fluorescent light in a digital camera using a solid-state imaging units in which the total quantity of light emitted within the exposure time of each pixel are different for each line even in the same frame or field. SOLUTION: The occurrence itself of the flicker is eliminated by making the exposure time of the solid-state imaging unit 12 to be an integer-multiple of 1/100 or 1/120 seconds, and a flicker correction gain is calculated for each area where flicker components are considered almost the same in one frame to perform flicker correction. Thus, a stable and excellent image without S/N dispersion within one frame and with no effect of the flicker on a moving object can be obtained without making a circuit large in scale. |
