Title: Basic noise reduction circuit for video camera
Inventor: SATO KAZUHIRO
IPC: H04N5/353
Filed: 1990-03-30
Abstract: PURPOSE:To reduce a basic noise, and to raise sensitivity especially at the time of high temperature and low intensity of illumination by inverting the basic noise of one frame portion to be generated in a solid state image pickup element in a dark state that a diaphragm means is closed, and adding it to a signal at the time of usual image pickup so that a basic noise component is removed. CONSTITUTION:A basic noise detecting means (consisting of an A/D converter 7, a frame memory 8, and a D/A converter 9) stores one frame portion of the basic noise generated in the solid state image pickup element 2 in the dark state that the diaphragm means 1 is closed for one frame period in conformity to the control of a control means 12. A basic noise removing means 10 inverts the stored basic noise of one frame portion, and cancels the basic noise component by adding it to the output signal of the solid state image pickup element 2 at the time of the usual image pickup. Thus, the basic noise of the video camera is reduced, and the sensitivity at the time of the high temperature and the low intensity of illumination can be raised.

Title: Automatic sweep digital tuning circuit
Inventor: TAKEBE HIDEJI
IPC: H03J7/06
Filed: 1980-06-23
Abstract: PURPOSE:To draw in the sweep to the most suited tuning point, by retarding the sweep a little and correcting the overshoot, after the stop of automatic sweep. CONSTITUTION:An up-pulse is transmitted from an automatic sweep control circuit 2 to an up-down-counter 3 at a switch means 1, the counter 3 makes up-count, the digital output is applied to a varactor diode of a tuner 5 via a D/A converter 4 and the tuning frequency of the tuner 5 is swept to high frequency side. When the tuning frequency comes to the most suited tuning point, the sweep is stopped and the digital output of the counter 3 is shifted to higher frequency due to the delay in time of the D/A conversion and the response of an AFC voltage from the optimum tuning point. The correction is made by transmitting the down-pulse from a down-pulse application means 7 to the counter 3. Thus, the tuning frequency can be drawn into the optimum tuning point with an automatic frequency fine tuning circuit 5 to be succeedingly operated.
