Abstract

See full text

A photoelectric conversion apparatus includes a light receiving circuit configured to convert light into an electrical signal, a readout circuit configured to read out an analog signal corresponding to the electrical signal, a ΔΣ A/D converter configured to convert the analog signal into a digital signal, and a control circuit configured to change a gain of the photoelectric conversion apparatus in accordance with a change of a driving mode of the photoelectric conversion apparatus. The analog signal read out by the readout circuit is an analog current signal. The readout circuit includes a variable resistor on a signal path for supplying the analog current signal to the ΔΣ A/D converter. The control circuit changes the gain of the photoelectric conversion apparatus by changing a resistance value of the variable resistor.
