摘要:
An imaging apparatus for capturing a moving image performs backlight correction of an image and outputs a natural image. The imaging apparatus electronically captures an image of a subject. An optical system has a light amount adjustment function. An imaging unit reads an optical image of the subject that is formed by the optical system. An A/D converter subjects an output of the imaging unit to A/D conversion. A backlight correction unit converts the tones of an image read by the A/D converter using a conversion characteristic selected differently according to a spatial position and at least increases the luminance level of a dark region of the image. An instruction unit instructs to start backlight correction. A control unit operates the backlight correction unit based on an instruction signal output from the instruction unit, and decreases an exposure light amount of the optical system by a predetermined amount.
