Claim Text:
1. An apparatus for calculating a flicker-evaluation value, the apparatus comprising: a first calculator configured to calculate a first difference between a pixel value of a long exposure image of a current frame and a pixel value of a long exposure image of a previous frame; an average calculator configured to calculate an average of the pixel value of the long exposure image of the current frame and the pixel value of the long exposure image of the previous frame; a second calculator configured to calculate a second difference between a pixel value of a short exposure image of the current frame and the average calculated by the average calculator; a flicker-evaluation value calculator configured to calculate a flicker-evaluation value which indicates a flicker strength using the first difference and the second difference; and a synthesizer configured to synthesize the long exposure image of the current frame and the short exposure image of the current frame based on the flicker-evaluation value.
