<P>PROBLEM TO BE SOLVED: To provide an imaging device capable of avoiding deterioration in color reproduction due to elimination of an infrared cut filter. <P>SOLUTION: An imaging device comprises: an imaging element 103 in which a pixel W for a total wavelength band, a W-R pixel for R, a W-G pixel for G and a W-B pixel for B are repeatedly arranged; a filter 102 which is provided on a front surface of the imaging element 103 and configured so that a part corresponding to the pixel W makes a total wavelength band in a wavelength band of a given area pass, and a part corresponding to each of the W-R pixel, the W-G pixel and the W-B pixel reflects a wavelength band of each color corresponding thereto; a reflection amount calculation section 113 for calculating a signal value of R, G, B by subtracting an image reading signal value of each of the W-R pixel, the W-G pixel and the W-B pixel from an image reading signal value of the pixel W; a color difference component generation section 115 for generating a color difference signal based on a signal value of R, G, B; and a luminance signal generation section 112 for generating a luminance signal using the image reading signal of the W pixel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
