IPC: H01L31/02
Filed: 1986-06-24
Abstract: PURPOSE:To simplify an electric constitution in a camera by switching gains associatively with an exposure factor other than the brightness of a subject and obtaining a proper resolution voltage value. CONSTITUTION:A switch SW3 is opened and either of switches SW1 and SW2 is closed according to the sensitivity ISO of a film as an object of light measurement. When the switch SW1 is closed, the gain A of an operational amplifier 11 is set to X1 and the integral voltage Vf of a capacitor 12 which is charged with a photocurrent (i) is outputted as an output voltage V01. Further, when the switch SW2 is closed, the capacitor 12 and a gain switching resistance 14 are connected to each other, so an output voltage V02 is Vf.(r1+r2)/r1. Here, r1 is the resistance value of a feedback resistance 16 and r2 is the resistance value of the gain switching resistance 14. Consequently, the output voltage V02 when the switch SW2 has a voltage level (r1+r2)/r1 times as large as that of the output voltage V01 when the switch SW1 is closed.
