Claim One:
1. An image processing apparatus comprising: a calculating unit configured to calculate an evaluation amount of color tone of an eye for a pixel in an image; an extracting unit configured to extract a candidate pixel indicating poor color tone of the eye on the basis of the evaluation amount calculated by the calculating unit; an area combining unit configured to determine a distance between a plurality of candidate areas by using a threshold for determining the distance between the plurality of candidate areas consisting of candidate pixels extracted by the extracting unit, to determine a shape of a circumscribed area by using an aspect ratio of the area circumscribed by the plurality of candidate areas, and to combine the plurality of candidate areas in accordance with determination results of the distance between the plurality of candidate areas and the shape of the circumscribed area, wherein the calculating unit applies weights to an R component and a G component of the image, applies a weight smaller than the weights of the R component and the G component to a B component of the image, and calculates the evaluation amount from the R component, the G component and the B component of the image to which the weights have been applied.
