<P>PROBLEM TO BE SOLVED: To provide a crosstalk amount measurement device, a color correction device, and a crosstalk amount measurement method that are capable of simply and inexpensively measuring a crosstalk amount to an adjacent pixel in a solid-state image sensor. <P>SOLUTION: Luminous flux carrying subject image information from a subject 31 is imaged on a light receiving surface of an image sensor 13 by an imaging lens 12, and is subjected to photoelectric conversion to generate an image signal. Thereafter, process processing is performed in a process circuit 14, and an MTF value is calculated in an MTF measurement unit 15 for the image signal of the subject 31. Though the calculated MTF value is input to a crosstalk amount calculation unit 16, in the crosstalk amount calculation unit 16, relation between an MTF value and a crosstalk amount is prestored in the format of a table (or a calculation formula), and a crosstalk amount of the image sensor 13 is calculated according to the MTF value input from the MTF measurement unit 15 using the table (or the calculation formula). <P>COPYRIGHT: (C)2012,JPO&INPIT |
