PHOTOELECTRIC CONVERSION DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282787 titled 'PHOTOELECTRIC CONVERSION DEVICE
The patent application describes a photoelectric conversion device with multiple pixels, each containing a photoelectric conversion unit, charge holding unit, and transfer transistors for managing charges generated by incident light.
- Photoelectric conversion unit generates charges based on incident light.
- First transfer transistor moves charges from the conversion unit to the charge holding unit.
- Second transfer transistor transfers charges from the holding unit to a first node.
- Third transfer transistor moves charges from the conversion unit to a second node.
- Two types of reading processes are performed in parallel: one for gradation signals and one for event signals related to changes in light intensity.
Potential Applications: - Digital cameras - Image sensors - Surveillance systems - Medical imaging devices
Problems Solved: - Efficient charge transfer within pixels - Accurate reading of gradation and event signals
Benefits: - Improved image quality - Enhanced low-light performance - Higher sensitivity to light changes
Commercial Applications: Title: "Advanced Image Sensor Technology for Enhanced Performance in Digital Cameras" This technology can revolutionize the digital camera market by providing superior image quality and performance, attracting professional photographers and enthusiasts alike.
Questions about the technology: 1. How does this photoelectric conversion device improve image quality in digital cameras? 2. What sets this technology apart from existing image sensor technologies?
Original Abstract Submitted
a photoelectric conversion device including a plurality of pixels, each of the plurality of pixels including: a photoelectric conversion unit configured to generate charges according to incident light; a charge holding unit; a first transfer transistor configured to transfer charges from the photoelectric conversion unit to the charge holding unit; a second transfer transistor configured to transfer charges from the charge holding unit to a first node; and a third transfer transistor configured to transfer charges from the photoelectric conversion unit to a second node. in one of the plurality of pixels, first reading processing of reading a gradation signal indicating a light amount of the incident light based on the charges transferred to the first node and second reading processing of reading an event signal indicating a change in the light amount of the incident light based on the charges transferred to the second node are performed in parallel.
