PURPOSE:To form the color video camera device by which the picture quality with high sensitivity and high resolution can be obtained by installing the pickup tube obtaining the luminance signal and the solid pickup element obtaining the chrominance signal. CONSTITUTION:The incident light through the lens 2 from the subject 1 is branched with the half mirror 3 and one is incident upon the pickup tube 4. On the other hand, the incident light is incident upon the solid pickup element 6 which is provided with the color filter through the crystal filter 3. Next, after the luminance signal current from the pickup tube 4 is amplified with the pre- amplifier 7, the current is suitably processed and becomes the luminance signal YH. On one hand, after the chrominance signal currents (r), (g) and (b) are amplified with the pre-amplifier 10, the currents are suitably processed, are guided to the color difference matrix 17 and become the color difference signal R-YL and B-YL necessary to generate the video signal. In such a way, the color video camera device, by which the picture quality with high sensitivity and high resolution can be obtained, can be formed. |
