IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240282792 titled 'IMAGE SENSOR
The abstract of the patent application describes an image sensor that includes a substrate with a pixel region and an optical black region, which contains a dummy pixel region next to the pixel region. The sensor also features a first color filter array on the pixel region and a second color filter array on the dummy pixel region. The second color filter array includes a first filter transparent to a first ray and a second filter transparent to a second ray.
- The image sensor includes a substrate with distinct pixel and optical black regions.
- A first color filter array is placed on the pixel region, while a second color filter array is on the dummy pixel region.
- The second color filter array consists of a first filter transparent to a first ray and a second filter transparent to a second ray.
Potential Applications: - Digital cameras - Smartphone cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Improved image quality - Reduction of noise in captured images - Enhanced color accuracy
Benefits: - Higher quality images - Better color reproduction - Reduced noise in low-light conditions
Commercial Applications: Title: Advanced Image Sensors for Enhanced Photography This technology can be used in various commercial applications such as digital cameras, smartphones, surveillance systems, and medical imaging devices. The improved image quality, color accuracy, and noise reduction make it a valuable addition to any imaging device.
Questions about Image Sensors: 1. How does the placement of the color filter arrays impact image quality? The placement of the color filter arrays on the pixel and dummy pixel regions helps enhance color accuracy and reduce noise in captured images.
2. What are the potential applications of image sensors with dual color filter arrays? Image sensors with dual color filter arrays can be used in a wide range of devices, including digital cameras, smartphones, surveillance systems, and medical imaging devices, to improve image quality and color accuracy.
Original Abstract Submitted
an image sensor includes: a substrate including a pixel region and an optical black region, the optical black region including a dummy pixel region adjacent to the pixel region; a first color filter array on the pixel region; and a second color filter array on the dummy pixel region, wherein the substrate has a first surface, each of the first color filter array and the second color filter array is on the first surface of the substrate, and the second color filter array includes: a first filter that is transparent to a first ray; and a second filter that is transparent to a second ray.
