<p><P>PROBLEM TO BE SOLVED: To provide a technology for obtaining photograph reproduction having more natural tones. <P>SOLUTION: An image processing apparatus generates image data having a high dynamic range by combining a plurality of image data having different exposure amounts. The image processing apparatus includes: an input means configured to input a plurality of M-bit image data to be combined; a determining means configured to determine reference image data serving as an exposure reference from among the plurality of input M-bit image data; a composition means configured to combine the plurality of M-bit image data and generate one N-bit composite image data (N>M); a characteristic parameter setting means configured to set a characteristic parameter of tone compression on the N-bit composite image data such that a predetermined reference luminance in the reference image data does not change; and a generating means configured to generate M-bit composite image data by compressing a luminance tone of an image component lower than a predetermined frequency included in the N-bit composite image data based on the set characteristic parameter. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
