AUTOMATIC SIGNAL CONTROL FOR A SOLID-STATE IMAGE SENSOR HAVING MULTIPLE OUTPUT REGISTERS |
摘要 |
A signal processing apparatus includes a first loop circuit for adjusting gains of a plurality of variable gain amplifiers to which signals output from a charge-coupled device (CCD) imager of multiple-channel reading type are applied, a control circuit for driving and controlling an iris in accordance with output signals from the plurality of variable gain amplifiers, a second loop circuit for adjusting levels of pilot signals to be superimposed upon the output signals of the CCD imager at a desired level, respectively, a third loop circuit for controlling levels of the pilot signals which are superimposed upon the output signals of the CCD imager so as to be coincident with each other, and a control unit for controlling the first loop circuit and the control circuit, the second loop circuit, and the third loop circuit so that they are operated in a time-division fashion. <IMAGE> |
