ABSTRACT:
In a photographing apparatus, while a deterioration of a contrast characteristic caused by an optical zooming operation is prevented, superior photographic images are continuously acquired. Magnification set by an optical zooming function is acquired, and a gamma curve, namely gradation correcting information is set to a gamma lookup table, while the gamma curve is applied during a photographing operation based upon the acquired set magnification. A gamma correcting unit corrects gradation of image data (namely, RAW data) outputted from an imaging element by employing gradation correcting information set in this gamma lookup table.
