IMAGING DEVICE INCLUDING PHOTOELECTRIC CONVERTERS AND CAPACITOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240313012 titled 'IMAGING DEVICE INCLUDING PHOTOELECTRIC CONVERTERS AND CAPACITOR
The abstract describes an imaging device with two photoelectric converters of different sizes, generating different signal charges.
- The device includes a semiconductor substrate, a first photoelectric converter generating a first signal charge, a first node for inputting the first signal charge, a capacitor connected to the first node, and a second photoelectric converter generating a second signal charge.
- The second photoelectric converter has a larger area than the first one, leading to different saturation charge capacities in the imaging cells.
- This innovation allows for improved image quality and dynamic range in the captured images.
- By utilizing different sizes of photoelectric converters, the device can optimize the performance of each imaging cell.
- The technology could be applied in digital cameras, smartphones, medical imaging devices, and other imaging systems requiring high-quality image capture.
Potential Applications: - Digital cameras - Smartphones - Medical imaging devices - Surveillance cameras
Problems Solved: - Improved image quality - Enhanced dynamic range - Optimized performance of imaging cells
Benefits: - Higher quality images - Increased dynamic range - Enhanced performance in various imaging applications
Commercial Applications: Title: Advanced Imaging Devices for Enhanced Image Quality This technology could revolutionize the digital imaging industry by providing devices with superior image quality and dynamic range, appealing to professional photographers, medical professionals, and consumers looking for high-quality imaging solutions.
Questions about the technology: 1. How does the size difference between the two photoelectric converters impact the performance of the imaging device? 2. What are the specific advantages of having different saturation charge capacities in the imaging cells?
Original Abstract Submitted
