Abstract
A solid-state image taking apparatus includes a photodiode converting incident light into a corresponding signal voltage. A measurement is given of a time until the signal voltage reaches a predetermined reference voltage. The measurement is executed by counting up pulses of a clock pulse signal during the time until the signal voltage reaches the reference voltage. The number of the counted pulses represents the time until the signal voltage reaches the reference voltage. The intensity of the incident light determines the time until the signal voltage reaches the reference voltage. Accordingly, the number of the counted pulses represents the intensity of the incident light.
