PHOTOELECTRIC CONVERSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603711 titled 'PHOTOELECTRIC CONVERSION DEVICE
The patent application describes a photoelectric conversion device that includes a light receiving unit and multiple pixel control units.
- The first pixel control unit controls the exposure period of the first pixel based on an exposure control signal and generates a delayed exposure control signal for the second pixel control unit.
- The second pixel control unit adjusts the exposure period to coincide with or follow the first exposure period based on the control signals received.
- This system allows for precise control of exposure periods in different pixels, improving overall image quality and performance.
Potential Applications: - This technology can be used in digital cameras, smartphones, and other imaging devices to enhance image quality and dynamic range. - It can also be applied in surveillance systems, medical imaging equipment, and scientific instruments for accurate image capture.
Problems Solved: - Provides a solution for controlling exposure periods in individual pixels, leading to better image quality and dynamic range. - Helps in reducing noise and improving overall performance of photoelectric conversion devices.
Benefits: - Improved image quality and dynamic range. - Enhanced performance and accuracy in image capture. - Versatile applications in various industries.
Commercial Applications: - This technology can be utilized in the development of high-quality cameras, smartphones, and other imaging devices for commercial sale. - It can also be integrated into surveillance systems, medical imaging equipment, and scientific instruments for commercial use.
Questions about the technology: 1. How does this technology improve image quality in photoelectric conversion devices? 2. What are the potential commercial applications of this innovation?
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.
