PURPOSE:To obtain high horizontal/vertical image resolution, by obtaining high band luminance signals from the output of a single image pickup element and at the same time obtaining the low band luminance signals and color signals from the residual branch output to combine these signals. CONSTITUTION:The low band luminance signal YL22 and color signals R23 and B24 are obtained at one time by a solid-state image pickup element 1. These signals can be obtained just by obtaining the sum or difference of two element which are horizontally adjacent to each other or adjacent with every second element. This the vertical image resolution of the luminance signal is parallel to that of the color signal in the black/white photograhing mode. While the high band luminance signal YH is obtained by obtaining the sum of the two elements which are vertically adjacent to each other with every second element. With combination of these signals, the color video signals are obtained with the horizontal/vertical image resolution of a high level as that obtained in the case of the black/white photography. |
