<p>A solid state color image pickup apparatus easily converts an output from a solid state image sensor to a television signal with a simple structure, thereby facilitating the reduction of the size, weight, power consumption and cost of the image pickup apparatus. A color filter (30), which has a plurality of color filter elements respectively facing light receiving elements (35, 36) of a solid state image sensor (31), modulates optical information so that: an image pickup signal output from the solid state image sensor (31) is composed of a luminance signal component and modulated color signal components, which are obtained by modulating, with two color-difference signals, two carrier waves having phases different from each other by pi /2; the phases of the two carrier waves are different by pi every horizontal scanning period in each field of a television signal; and the luminance signal component has a spectral characteristic substantially the same as that of a luminance signal of a standard television system, the first color-difference signal has a spectral characteristic substantially the same as that of a signal obtained by subtracting the luminance signal of the standard television system from a red signal of the standard television system, and the second color-difference signal has a spectral characteristic substantially the same as that of a signal obtained by subtracting the luminance signal of the standard television system from a blue signal of the standard television system. <IMAGE></p> |
