Photoelectric conversion device |
摘要 |
A photoelectric conversion device comprises a control circuit for applying a control signal to a control electrode of a photoelectric transducer, an operating point detection circuit for receiving an output signal from the photoelectric transducer and inverting an output state thereof depending on a level of the output signal, and a sample/hold circuit controlled by an output of the operating point detection circuit to hold a signal level corresponding to the control signal as developed when the output state of the operating point detection circuit is inverted, the signal held by the sample/hold circuit being read as a photoelectrically converted output. Photoelectric conversion characteristics thereby exhibits good linearity.
