APPARATUS AND METHOD FOR IMAGE PROCESSING INCLUDING PHOTOMETRY AND COLORIMETRY

The present invention provides an image processing apparatus comprising: a principal object extraction device which extracts a shape of a principal object from an overall screen of an image entered, a weighted area determining device which determines a plurality of areas including the area of the principal object that matches the shape of the extracted principal object as a weighted area, a weighting factor determining device which determines a weighting factor for each of the determined weighted areas, a measuring device which divides the overall screen into a plurality of areas and calculates measured values of divided photometry and/or divided colorimetry for each divided area, and a correction device which performs exposure correction and/or white balance correction based on a measured value calculated for each divided area and a weighting factor determined for each of the weighted areas to which the divided area of each measured value belongs.
