This color filter (19) is constituted by a tristimulus color filter for wavelength-selecting and transmitting red light, green light and blue light. Mixing of blue color and red color is prohibited by not having the transmission wavelength band of the red filter CFR overlaid substantially on the transmission wavelength band of the blue filter CFB.

Abstract: It is an object of the present invention to provide signals which allow colors in a wider color range than predetermined standards, which can be handled by apparatus according to such predetermined standards. A primary color converter 62 converts first color signals having primary color points in a wider color range than the primary color points according to BT.709 into second color signals based on the primary colors according to BT.709. A photoelectric transducer 63 converts the second color signals into third color signals according to photoelectric transducer characteristics defined in a numerical range wider than a range from 0 to 1.0 of color signals corresponding to a luminance signal and color difference signals according to BT.709. A color signal converter 64 converts the third color signals into a luminance signal and color difference signals. A corrector 64A incorporated in the color signal converter corrects the color difference signals into color difference signals in a range from −0.57 to 0.56 containing a range from −0.5 to 0.5 according to BT.709, which color difference signals are assigned to an integral value in a range from 1 to 254 containing a range from 16 to 240 according to BT.709. The present invention is applicable to a video camera, for example.
