Photoelectric conversion apparatus and device for outputting gradation and event patterns at different rates

Abstract

A conversion apparatus includes a pixel array unit in which a plurality of first pixels that generates gradation signals indicating amounts of incident light and a plurality of second pixels that generates event signals are two-dimensionally disposed, a reading unit configured to read the gradation signals and the event signals from the pixel array unit, and a control unit configured to change an output data rate of the gradation signals and an output data rate of the event signals, wherein a first pattern for outputting the gradation signals at a first output data rate and outputting the event signals at a second output data rate and a second pattern for outputting the gradation signals at a third output data rate different from the first output data rate and outputting the event signals at a fourth output data rate different from the second output data rate are switched.
