PHOTOELECTRIC CONVERSION DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240310491 titled 'PHOTOELECTRIC CONVERSION DEVICE

The patent application describes a photoelectric conversion device with a unique pixel control mechanism.

  • The device includes a light receiving unit and multiple pixel control units.
  • A first pixel control unit controls the exposure period of a first pixel based on an exposure control signal.
  • It generates a delayed exposure control signal for a second pixel control unit.
  • The second pixel control unit adjusts the exposure period to coincide or follow the first pixel's exposure period.

Potential Applications:

  • This technology can be used in digital cameras, smartphones, and other imaging devices.
  • It can improve image quality by optimizing exposure control for each pixel.

Problems Solved:

  • Enhances image quality by controlling exposure periods effectively.
  • Allows for better capture of details in varying lighting conditions.

Benefits:

  • Improved image quality and detail capture.
  • Enhanced performance in low-light conditions.
  • Optimal exposure control for each pixel.

Commercial Applications:

  • This technology can be valuable for camera manufacturers, smartphone companies, and other imaging device producers.
  • It can lead to the development of high-quality imaging products with superior performance.

Questions about the Technology: 1. How does this pixel control mechanism improve image quality? 

  - This mechanism optimizes exposure control for each pixel, resulting in better detail capture and enhanced image quality.

2. What are the potential applications of this technology beyond digital cameras and smartphones? 

  - This technology can also be applied in security cameras, medical imaging devices, and scientific instruments for improved image processing and analysis.


Original Abstract Submitted

a photoelectric conversion device includes a light receiving unit and a plurality of pixel control units. a first pixel control unit controls a first exposure period in a first pixel among a plurality of pixels based on a first exposure control signal, generates a second exposure control signal by delaying the first exposure control signal, and outputs the second exposure control signal to a second pixel control unit. when the first exposure control signal is enabled, the second pixel control unit controls a second exposure period such that a start time of the second exposure period coincides with a start time of the first exposure period. when the second exposure control signal is enabled, the second pixel control unit controls the second exposure period such that the start time of the second exposure period is later than the start time of the first exposure period.
