发明名称 Imaging apparatus
摘要 An imaging apparatus includes a selecting part selecting a first mode where correction of dark area gradation is not performed or a second mode where the correction is performed, and a correcting part performing the correction of improving lightness of dark area gradation of an image data when the second mode is selected; wherein an exposure calculating part calculates a brightness value for exposure control by calculating at least one of the maximum brightness value, the average brightness value, and a central part brightness value based on an output of a photometry part and by adding results by weighting addition; and determines a correction value by adding the results by weighting addition and corrects the brightness value for exposure control based on the correction value if the second mode is selected. Therefore, optimum exposure adjustment that depends on the correction can be performed.
