Abstract:
1. An image processing apparatus, comprising: an obtaining unit configured to obtain an image signal; a calculator programmed to calculate evaluation values including at least chroma information on a basis of the image signal obtained by the obtaining unit, for each of several areas in an image represented by the image signal; a detector that detects an object area from the image signal; a discriminator that discriminates, with a processor, whether a scene of the image represented by the image signal is a vivid color scene or not, on a basis of a discrimination criterion and at least some of the evaluation values calculated by said calculator; an output unit configured to output a discrimination result discriminated by said discriminator; a storage unit configured to store a past evaluation value calculated by said calculator; and a motion amount detection unit configured to detect a motion amount of an input image, wherein said discriminator discriminates whether the image is vivid color or not by using the past evaluation value stored in said storage unit as an evaluation value of the object area detected by said detector if the motion amount detected by said motion amount detection unit is smaller than a predetermined value, and wherein said discriminator loosens the discrimination criterion if the object area is detected by the detector as compared with the discrimination criterion in a case where the object area is not detected by the detector and if the scene of the image was discriminated as being vivid color in the past.
