Patent ID: 7486312

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 conesponds 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 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 the flesh-colored pixel average luminance value and a predetermined value, wherein the brightness adjustment by the brightness adjustment module is executed by using a linear characteristic line that determines output values from input values, the linear characteristic line being a tone curve that is characterized in having an output value of the predetermined value in response to an input value of the flesh-colored pixel average luminance value.
