  • Publication number: 20240284060
    Abstract: An image capturing apparatus comprises a pixel region having a plurality of pixels configured to generate and output event signals upon detecting a variation in quantity of incident light and a readout circuit configured to read out the event signals output from the pixel region. The readout circuit counts the number of the event signals read out from the pixel region, and when the number of the counted event signals exceeds a preset threshold within a predetermined period, the readout circuit discards the event signals read out from the pixel region, and transmits an acknowledge signal to the pixel region.
