PIXEL ARRAY ACCUMULATING PHOTOCHARGES IN EACH UNIT FRAME, AND IMAGE SENSOR INCUDING THE PIXEL ARRAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17879497 titled 'PIXEL ARRAY ACCUMULATING PHOTOCHARGES IN EACH UNIT FRAME, AND IMAGE SENSOR INCUDING THE PIXEL ARRAY
Simplified Explanation
The patent application describes a pixel array with multiple pixels, each containing a photodiode that generates a photocharge. The pixels also have a floating diffusion node to receive the photocharge. Additionally, there are two storage capacitors in each pixel to store the photocharge generated during different time periods in each frame.
- The pixel array consists of multiple pixels with photodiodes and storage capacitors.
- Each pixel generates a photocharge using its photodiode.
- The photocharge is received by a floating diffusion node in each pixel.
- There are two storage capacitors in each pixel to store the photocharge generated during different time periods in each frame.
Potential applications of this technology:
- Image sensors in digital cameras and smartphones
- Surveillance cameras and security systems
- Medical imaging devices such as X-ray machines and ultrasound scanners
- Automotive cameras for advanced driver-assistance systems
Problems solved by this technology:
- Efficiently capturing and storing photocharges generated by photodiodes
- Improving the performance and sensitivity of image sensors
- Reducing noise and improving image quality
Benefits of this technology:
- Higher resolution and image quality in captured photos and videos
- Improved low-light performance and sensitivity
- Reduced noise and better signal-to-noise ratio
- Enhanced performance in various imaging applications
Original Abstract Submitted
Provided is a pixel array including a plurality of pixels, each of which includes a photodiode configured to generate a photocharge in a frame including a plurality of unit frames, a floating diffusion node configured to receive the photocharge, a first storage capacitor configured to receive and store a first photocharge generated by the photodiode through the floating diffusion node during a first unit accumulation time period in each of the plurality of unit frames, and a second storage capacitor configured to receive and store a second photocharge generated by the photodiode through the floating diffusion node during a second unit accumulation time period in each of the plurality of unit frames.
