IPC: H04N5/372
Filed: 1990-11-13
Abstract: PURPOSE:To obtain a video signal without a dark current by storing shading by a dark current of a CCD image sensor, outputting the result as an analog signal and synthesizing it with an output of a temperature sensor so as to use the synthesized signal for gain control. CONSTITUTION:For example, a dark current signal obtained when a lens cap is put on the camera is given to an LPF 4 and an A/D converter 6, and a dark current signal by one TV frame is stored in a frame memory 7 by depressing a switch 10. The signal is converted into an analog signal by a D/A converter 8 and the signal is adjusted at a control circuit 12 with respect to a normal temperature change by the control of a temperature sensor 11 and the result is fed to an inverting input of a subtractor circuit 9. The circuit 12 is acted so that the gain is doubled with respect to a temperature rise of 8 deg.C.
