IMAGE SENSING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240313023 titled 'IMAGE SENSING DEVICE
The patent application describes an image sensing device that includes two substrates, each with different photoelectric conversion elements to respond to different types of light.
- The first substrate has a first infrared photoelectric conversion element that detects infrared light and a color photoelectric conversion element that detects visible light.
- The second substrate, stacked on the first, contains a second infrared photoelectric conversion element that captures infrared light passing through the first infrared element.
Potential Applications: - Surveillance systems - Night vision cameras - Medical imaging devices
Problems Solved: - Enhanced sensitivity to both infrared and visible light - Improved image quality in various lighting conditions
Benefits: - Clearer images in low light environments - Versatile applications in different industries - Enhanced overall performance of image sensing devices
Commercial Applications: Title: Advanced Image Sensing Technology for Enhanced Surveillance Systems This technology can be used in security cameras, medical imaging devices, and other applications requiring high-quality image capture in various lighting conditions.
Questions about the technology: 1. How does this technology improve image quality in low light conditions? 2. What are the key advantages of having separate photoelectric conversion elements for infrared and visible light detection?
Original Abstract Submitted
an image sensing device includes a first substrate and a second substrate. the first substrate includes a first infrared photoelectric conversion element structured to respond to infrared light to generate photocharges corresponding to an intensity of infrared light received by the first infrared photoelectric conversion element, and a color photoelectric conversion element structured to respond to visible light to generate photocharges corresponding to an intensity of visible light received by the color photoelectric conversion element. the second substrate stacked on the first substrate and configured to include a second infrared photoelectric conversion element structured to respond to infrared light to generate photocharges corresponding to an intensity of infrared light that passes through the first infrared photoelectric conversion element and is received by the second infrared photoelectric conversion element.
