An imaging apparatus includes an image pickup unit generating image data, a selecting unit selecting any one of a first photographic mode that does not correct dark area gradation of the image data and a second photographic mode that corrects the dark area gradation of the image data, a gradation conversion processing unit performing a gradation conversion processing according to a first input-output characteristic when the first photographic mode is selected, and performing a gradation conversion processing according to a second input-output characteristic different from the first input-output characteristic when the second photographic mode is selected, and a correcting unit performing a correction of improving lightness of the dark area gradation of the image data when the second photographic mode is selected. Therefore, when correction of the dark area gradation is performed, the lightness of the whole image can be maintained while the contrast of a highlight area is improved. |
