IMAGE SENSING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240264281 titled 'IMAGE SENSING DEVICE
The patent application describes an image sensing device with a pixel array that responds to incident light to produce photocharges.
- First detection structure with a first control node and a first detection node, surrounded by a second detection structure with a second control node and a second detection node.
- First storage diode connected to the first detection node, and a second storage diode connected to the second detection node.
- The first and second detection structures are positioned at opposing vertices of a pixel, facing each other diagonally within the pixel.
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Improved light detection and image quality - Enhanced pixel sensitivity
Benefits: - Higher resolution images - Better low-light performance - Reduced noise in captured images
Commercial Applications: Title: Advanced Image Sensors for Enhanced Photography and Surveillance This technology can be used in high-end digital cameras, security cameras, and medical imaging equipment, enhancing image quality and sensitivity.
Questions about the technology: 1. How does this image sensing device improve image quality compared to traditional sensors?
- The device's unique pixel array structure allows for more accurate detection of incident light, resulting in higher quality images.
2. What are the potential cost implications of implementing this technology in commercial products?

Original Abstract Submitted
an image sensing device includes a pixel array including pixels, each pixel structured to respond to incident light to produce photocharges indicative of detected incident light. the pixel array includes: a first detection structure configured to include a first control node receiving a first demodulation control signal and a first detection node disposed to surround the first control node; a second detection structure configured to include a second control node receiving a second demodulation control signal and a second detection node disposed to surround the second control node; a first storage diode electrically connected to the first detection node; and a second storage diode electrically connected to the second detection node, wherein the first detection structure and the second detection structure are disposed at two opposing vertices of a pixel, respectively, to face each other in a diagonal direction within the pixel.
