PROBLEM TO BE SOLVED: To solve the problem in which, when changing gamma correction characteristics to give an effect to a video, when overall brightness changes, a desire effect cannot be given.SOLUTION: The imaging apparatus changes gamma correction characteristics according to a change of an evaluation value, when gamma correction characteristics other than reference and changes the gamma correction characteristics so that a power ratio to the gamma correction characteristics is kept unchanged when an input value is different by the ratio of evaluation values.SELECTED DRAWING: Figure 2 |
