Patent ID: 8483507

Claim:
An image sensing apparatus comprising: a first tone correction unit which applies a tone correction that suppresses luminance saturation of image data; a second tone correction unit which applies a tone correction by converting luminance values of all luminance regions so that a maximum luminance value of sensed image data becomes a largest possible luminance value of the image data; a third tone correction unit which applies a tone correction by multiplying a luminance value of a low-luminance region, which is set in advance, of sensed image data by a gain larger than gains of other luminance regions; an analysis unit which analyzes a luminance distribution of sensed image data; a selection unit which selects at least one of tone corrections applied by said first, second, and third tone correction units as the tone correction to be implemented for sensed image data based on an analysis result of said analysis unit; and a limiting unit which limits, when the tone correction by said second tone correction unit is selected, implementation of the tone correction by said third tone correction unit.
