Light 2 that is the subject to be imaged enters a lens system 3, and the light is transmitted and absorbed by a color filter 5. The transmitted components enter an image sensor 4 to be imaged. The color filter 5 is composed of, as shown in FIG. 7B, a transparent pixel (W) and micro filters including a filter (W-X) with a complementary color for the color matching function X, a filter (W-Y) with a complementary color for the color matching function Y, and a filter (W-Z) with a complementary color for the color matching function Z. Each of them is arranged to correspond in position to each pixel of the image sensor. As a result, light with components in the entire wavelength region, light with complementary color components of X, light with complementary color components of Y, and light with complementary color components of Z enter their respective pixels to be imaged. From such images, W-(W-X), W-(W-Y), and W-(W-Z) are calculated to reproduce an image corresponding to XYZ, whereby accurate color imaging is possible. Accordingly, accurate color values can be imaged with high light use efficiency.
