ABSTRACT:
A color image pickup system for a color television system comprises a single image pickup device, a color filter mounted in front of the screen of said image pickup device, said color filter having an array of the repetition of a pair of horizontal colored belts or scanning lines, the first scanning line having an arrangement of cells of the three elementary colors, the second scanning line having an arrangement of the complementary elementary colors to those of the first scanning line. Thus, the colors of each pair of cells in the vertical direction of the two scanning lines are complementary. The output of the image pickup device is processed by adding the signals of the first scanning line and the second scanning line for every vertical cell to provide a brightness signal(Y). As a color signal, only the first scanning line is selected and a pair of color cells (red and blue) are sampled. Thus, the horizontal resolution of the brightness signal is the same as that of the image pickup device itself, and a clear picture with high resolution is obtained in a single image pickup device system.
