Abstract:
1. An image processing apparatus which performs tone correction processing on an image inputted, the image processing apparatus comprising: an acquisition unit that acquires coordinate information on an object area which is an area where a predetermined kind of object exists in the inputted image; a division unit that divides the inputted image into a plurality of divided areas; a first decision unit that decides a tone correction coefficient for each of the divided areas related to the tone correction processing based on brightness information of each of the plurality of divided areas; a second decision unit that decides a tone correction coefficient related to tone correction processing on the object area based on coordinate information on the object area and tone correction coefficients for at least divided areas which have a common portion with the object area, among the plurality of divided areas; and an image processing unit that performs tone correction processing on the object area in the inputted image, by applying thereto the tone correction coefficient decided by the second decision unit in a uniform manner without depending on coordinates thereof, and that performs tone correction processing, in which weighted interpolation is carried out according to coordinates by the use of the tone correction coefficient for each of the divided areas decided by the first decision unit, on areas other than the object area in the inputted image.
