IMAGE CAPTURING APPARATUS, IMAGE CAPTURING SYSTEM, AND EQUIPMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18581648 titled 'IMAGE CAPTURING APPARATUS, IMAGE CAPTURING SYSTEM, AND EQUIPMENT

Simplified Explanation: The patent application describes an image capturing apparatus that includes a pixel region with pixels that generate event signals upon detecting changes in incident light, and a readout circuit that reads and counts these event signals. When the number of event signals exceeds a preset threshold within a set time frame, the readout circuit discards the signals and sends an acknowledge signal to the pixel region.

  • **Key Features and Innovation:**
   - Pixel region generates event signals based on light changes.
   - Readout circuit counts and processes event signals.
   - Discards event signals exceeding preset threshold.
   - Acknowledge signal sent to pixel region.
  • **Potential Applications:**
   - Surveillance systems
   - Motion detection cameras
   - Traffic monitoring devices
  • **Problems Solved:**

Original Abstract Submitted

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.
