Abstract
PURPOSE: To make automatic adjustment of white balance accurately by interlocking an auto-white initial control circuit and iris control mechanism together and by switching the iris control mechanism to an automatic key mode when the auto-white control circuit operates.
CONSTITUTION: This system is equipped with switching circuit 16 driven by auto- white driver circuit 6 which adjusts automatically white balance through the operation of auto-white driving switch 7 and auto-iris driver circuit 15 interlocking with the operation of switch 7 of this circuit 6. This circuit 16, composed of FET, is connected between automatic iris arithmetic circuit 12 and iris control output circuit 13 and in adjustment operation for white balance, circuit 16 is put invariably in an automatic operation mode by circuit 6 regardless of the operation position of an iris auto/manual alternation switch, so that automatic adjustments of white balance can be made accurately.
