COLOR CAMERA SYSTEM |
摘要 |
<p>A color camera system is disclosed in which a dot-like signal which appears on a TV screen caused by a processing error is effectively eliminated. A pick up device with a color coding filter derives composite signals containing color components modulated at a frequency fs where the composite signals are obtained in opposite phase line by line. An adder circuit is provided to mix the composite signals obtained from two adjacent lines. A detector detects the 2nd harmonic of fs from the mixed composite signals. A dual gate MOSFET is provided to suppress a high frequency region of a luminance signal which is derived from the composite signals in response to the detected 2nd harmonic of fs.</p> |
