Abstract:
1. An image processing apparatus, comprising: a principal object extraction device which extracts a shape of a principal object from an overall undivided screen of an inputted image; a weighted area determining device which determines an area of the principal object that matches the shape of the extracted principal object as a primary weighted area, and an area other than the area of the principal object as a secondary weighted area, and further divides the primary weighted area into a plurality of first weighted areas and the secondary weighted area into a plurality of second weighted areas; a weighting factor determining device which determines a different weighting factor at least for each first weighted area of the plurality of first weighted areas in the weighted area according to a position of each first weighted area in the principal object, respectively; a measuring device which divides the overall undivided screen of the inputted image into a plurality of measurement areas and calculates measured value(s) of divided photometry and/or divided colorimetry for each measurement area of the plurality of measurement areas; and a correction device which performs exposure correction and/or white balance correction with respect to a position in the image based on the measured value(s) calculated for the measurement area of the plurality of measurement areas corresponding to the position in the image and the weighting factor(s) determined for the one of the plurality of first and second weighted areas corresponding to the position in the image.
