IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18221736 titled 'IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor that includes different pixel groups, an autofocus pixel group, color filters, and a light-shield pattern. Here is a simplified explanation of the abstract:
- The image sensor has two pixel groups, each containing multiple pixels, with at least one pixel from each group adjacent to each other in a specific direction.
- Between the two pixel groups, there is an autofocus pixel group that includes an autofocus pixel adjacent to the first pixel group and another autofocus pixel adjacent to the second pixel group.
- The first autofocus pixel and the second autofocus pixel have color filters on them.
- The second pixel group has a different color filter compared to the autofocus pixels.
- A light-shield pattern is present to separate the color filters of the autofocus pixels and the second pixel group.
Potential applications of this technology:
- Digital cameras: The image sensor can be used in digital cameras to improve autofocus capabilities and image quality.
- Mobile devices: This technology can be implemented in smartphones and tablets to enhance camera performance and image capturing.
- Surveillance systems: The image sensor can be utilized in surveillance cameras to improve autofocus accuracy and image clarity.
Problems solved by this technology:
- Autofocus accuracy: The presence of autofocus pixels adjacent to the pixel groups helps in achieving accurate autofocus in the captured images.
- Image quality: The use of different color filters for the autofocus pixels and the second pixel group can enhance the color accuracy and overall image quality.
- Light interference: The light-shield pattern helps in preventing interference between the color filters, ensuring accurate color reproduction.
Benefits of this technology:
- Improved autofocus: The inclusion of autofocus pixels and their placement next to the pixel groups enhances the autofocus performance of the image sensor.
- Enhanced image quality: The use of different color filters and the light-shield pattern helps in producing images with better color accuracy and reduced interference.
- Versatile applications: The image sensor can be used in various devices, such as digital cameras, mobile devices, and surveillance systems, providing flexibility and improved imaging capabilities.
Original Abstract Submitted
An image sensor includes a first pixel group on a substrate and including a plurality of first pixels, a second pixel group on the substrate and including a plurality of second pixels, where at least one of the plurality of first pixels and at least one of the plurality of second pixels are adjacent in a first direction, a first autofocus pixel group between the first pixel group and the second pixel group, the first autofocus pixel group including a first autofocus pixel adjacent to the first pixel group and a second autofocus pixel adjacent to the second pixel group, a first color filter on the first autofocus pixel and the second autofocus pixel, a second color filter on the plurality of second pixels, and a light-shield pattern that separates the first color filter and the second color filter.
