Abstract

A solid state color television camera having a solid state image sensing device and an optical color filter. In this case, the color separating characteristics of the color filter is so selected that when a predetermined horizontal scanning line is scanned, from the solid state image sensing device there are obtained a red color signal and a luminance signal of the standard system sequentially and alternately, and from a horizontal scanning line adjacent the above horizontal scanning line there are obtained a blue color signal and luminance signal. Also, as the high band component, which constitutes the above luminance signal, the high band component of a composite video output signal, which includes the primary color signal and luminance signal produced by scanning the above horizontal scanning line, is utilized. Further, by scanning the respective horizontal scanning lines, different color difference output signals obtained at every one horizontal scanning line are made in simultaneity and based upon the color difference output signals and luminance signal there is produced a color video signal of the standard system.
