<P>PROBLEM TO BE SOLVED: To provide an image processing device that precisely corrects sensitivity characteristics of a light receiving element with smaller memory usage. <P>SOLUTION: A corrected original data input part 51 inputs a plurality of corrected original data items. A block upper limit determination part 52 determines the upper limit value of a splittable block by luminance in each corrected original data item to output a determined upper limit value to a block configuration part 54. A boundary detector 53 detects the boundary of pixel data for each plurality of input corrected original data items to output a detected boundary to the block configuration part 54. On the basis of the input boundary from the boundary detector 53, the block configuration part 54 integrates light receiving elements dj considered to have the same sensitivity characteristics into one block for all light receiving elements dj within the extent of the upper limit value. A correction value calculation part 55 calculates three kinds of average luminance values of white reference luminance, intermediate luminance, and black reference luminance for each block and calculates a correction value from third average luminance values of these three kinds to prepare a correction table. <P>COPYRIGHT: (C)2013,JPO&INPIT |
