Patent ID: 7932930

Claim:
An image processing device that executes image processing of image data, the image data being digital data of an image, the image processing device comprising: an image data acquisition module that acquires the image data; an image determination module that determines whether the image data is image data that corresponds to a backlit portrait image by analyzing the image data; a flesh-colored pixel average luminance value calculation module that calculates an average luminance value of flesh-colored pixels in the image data by analyzing the image data; and a brightness adjustment module that, if the image is determined to be a backlit portrait image, then executes a brightness adjustment of the image data by using a first linear characteristic line that determines output values from input values, the first linear characteristic line being a tone curve that is characterized in having an output value of a predetermined value in response to an input value of the flesh-colored pixel average luminance value and if the image is determined not to be a backlit portrait image, then executes a brightness adjustment of the image data by using a second linear characteristic line that determines output values from input values and is different from the first linear characteristic line.
