发明名称 Imaging apparatus
摘要 An imaging apparatus includes a photometry unit dividing a subject into a plurality of regions and performing a photometry, a first calculating unit calculating a first control value based on a photometry result of the photometry unit, a comparing unit comparing the first control value with a maximum value of photometry values in the plurality of regions, a second calculating unit correcting the first control value depending on a comparison result by the comparing unit to calculate a second control value, an image pickup unit picking up an image of the subject according to the second control value and generates an image data, and a third calculating unit calculating a lightness improvement amount for a correction of dark area gradation of the image data depending on the comparison result. Therefore, optimum exposure adjustment and correction of dark area gradation can be performed depending on the subject.
