Photoelectric conversion apparatus |
摘要 |
A photoelectric conversion apparatus includes a photoelectric conversion element and a logarithmic conversion unit for converting a signal from the photoelectric conversion element to a logarithmically compressed voltage by means of a diode characteristic of p-n junction. The p-n junction in the logarithmic conversion unit is composed of any two terminals of the emitter, the base and the collector of the bipolar transistor, and a residual terminal of the transistor is connected to a semiconductor substrate.
