IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18156685 titled 'IMAGE SENSOR
Simplified Explanation
The patent application describes an image sensor with a Bayer pattern-type pixel array and a signal processing unit.
- The pixel array consists of multiple extended blocks, each containing four pixel blocks.
- Each pixel block has four pixels, with the first and fourth pixels in the first and fourth blocks sensing green light.
- The first and fourth pixels in the second and third blocks sense red and blue light, respectively.
- The second and third pixels in all four blocks sense white light.
- The signal processing unit merges the color information from the first and fourth pixels and the illuminance information from the second and third pixels.
Potential applications of this technology:
- Digital cameras
- Smartphone cameras
- Surveillance cameras
- Medical imaging devices
Problems solved by this technology:
- Improved image quality by combining color and illuminance information from different pixels.
- Enhanced sensitivity to different wavelengths of light.
- Reduction of noise and artifacts in the final image.
Benefits of this technology:
- Higher quality and more accurate color reproduction in captured images.
- Improved low-light performance and dynamic range.
- Reduction of image noise and artifacts.
- Enhanced overall image sharpness and clarity.
Original Abstract Submitted
An image sensor includes a Bayer pattern-type pixel array including a plurality of Bayer pattern-type extended blocks each having first to fourth pixel blocks, each of the first to fourth pixel blocks including first to fourth pixels, the first and fourth pixels of the first and fourth pixel blocks being configured to sense green light, the first and fourth pixels of the second and third pixel blocks being configured to sense red light and blue light, respectively, and the second and third pixels of the first to fourth pixel blocks being configured to sense white light, and a signal processing unit merging Bayer pattern color information generated from the first and fourth pixels of the first to fourth pixel blocks, and the Bayer pattern illuminance information generated from the second and third pixels of the first to fourth pixel blocks.
