<p><P>PROBLEM TO BE SOLVED: To provide an image processing apparatus and an image processing method for obtaining a high contrast image with fine image quality. <P>SOLUTION: The image processing apparatus (10) is configured to synthesize a plurality of pieces of images photographing an identical scene and having different exposure amounts to generate a high-contrast image expanding a dynamic range and having a wide tonal range, and provided with: a selecting unit (11) for selecting a reference image based on the information of brightness components of pieces of images; a gain calculating unit (11) for calculating brightness ratios of remaining images among the pieces of images to the reference images excluding the reference image as gains based on the information of the brightness components of the pieces of images; a weight calculating unit (11) for calculating weight applied to the remaining images based on the gains and the information of the brightness components of the reference image; and a generating unit (11) for performing weighting synthesis between the reference image and the remaining images by using the weight to obtain a high contrast image. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
