<P>PROBLEM TO BE SOLVED: To provide an imaging device with the same gradation characteristics by applying gradation conversion processing to the first, second, and third photoelectric conversion characteristics, in an imaging device provided with an image pickup device having the first photoelectric conversion characteristic, the second photoelectric conversion characteristic different from the first photoelectric conversion characteristic, and the third photoelectric conversion characteristic indicating a transitional characteristic with the first and second photoelectric conversion characteristics. <P>SOLUTION: In an imaging device provided with an image pickup device having the first photoelectric conversion characteristic, the second photoelectric conversion characteristic different from the first photoelectric conversion characteristic, and the third photoelectric conversion characteristic indicating a transitional characteristic with the first and second photoelectric conversion characteristics, a characteristic converting portion converting the first, second, and third photoelectric conversion characteristic into a reference photoelectric conversion characteristic is provided. By applying gradation conversion processing to the first, second, and third photoelectric conversion characteristics, an imaging device with the same gradation characteristic of an entire image can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
