ABSTRACT:
An image sensing apparatus having an image sensing unit that converts light into an electric signal corresponding to a quantity of incident light, and outputs an image signal obtained by the conversion, and that outputs an image signal obtained by the conversion, a mode switch section that switches among a plurality of image sensing modes including at least a firework image sensing mode and a normal image sensing mode, a mode control section that changes gamma characteristics including a first gamma characteristic used in the firework image sensing mode and a second gamma characteristic used in the normal image sensing mode, and a gamma circuit that, when switch to the firework image sensing mode is made by the mode switch section, makes gamma conversion of the image signal output from the image sensing unit by using the first gamma characteristic selected by the mode control section. The first gamma characteristic includes a characteristic having the effect of suppressing a low luminance in comparison with the second gamma characteristic.
