IPC: H04N5/235
Filed: 1998-12-26
Abstract: PROBLEM TO BE SOLVED: To provide an exposure controller constituted so that proper exposure can be surely obtained even before a diaphragm is adjusted. SOLUTION: In a diaphragm control circuit 18, adjustment data stored in an EEPROM is read by a CPU when a power source is turned on. In the case that an adjustment finish flag included in the adjustment data is not set in a situation that the finish of adjustment is shown, a transistor for forcibly opening a diaphragm 108 is turned on and a transistor for driving a diaphragm 110 is forcibly turned on so that the opening action of the diaphragm by a diaphragm unit 17 is executed. Thus, since the quantity of incident light is increased, the gain of a sample holding and AGC circuit is fixed to OdB. When overexposure is caused on this condition, the electronic shutter function of a CCD is controlled so as to make the exposure proper. Then, when the exposure becomes proper, a viewing angle is adjusted.
