Method of adjusting white balance of image, recording medium having program for performing the method, and apparatus applying the method

摘要

A white balance adjusting apparatus and method generate a display image by performing display image signal processing to an input image, specify an area of the display image, output at least two sample images by applying at least two types of correction gains to the area of the display image, and apply the correction gain that is applied to one of the at least two sample images to the input image. Accordingly, a white subject does not have to be searched for to adjust white balance, and an image having a color sensitivity desired by the user can be obtained by performing white balance on colors other than white.

1. A method of adjusting white balance, the method comprising:
generating a display image by performing display image signal processing on an input image; outputting a representative color having a largest surface area of a selected area of the display image, the representative color output by a digital signal processor based on determining a color occupying the largest surface area of the selected area; simultaneously displaying at least two sample images corresponding to the selected area of the display image by applying different correction gains to the selected area of the display image that displays the output representative color, the at least two sample images being stored in a database; and applying the correction gain that is applied to a selected one of the at least two sample images to the input image.
