IMAGE SENSOR AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18210946 titled 'IMAGE SENSOR AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor with a pixel array that includes multiple pixels arranged in a two-dimensional pattern. Each pixel has three meta-photodiodes that absorb light of different wavelength bands. The arrangement of these meta-photodiodes in the central portion of the pixel array is the same as in the periphery, and their size is smaller than the diffraction limit.
- The image sensor includes a pixel array with multiple pixels.
- Each pixel has three meta-photodiodes that absorb light of different wavelength bands.
- The meta-photodiodes are arranged in a pattern within each pixel.
- The arrangement of meta-photodiodes is the same in the central portion and the periphery of the pixel array.
- The size of the meta-photodiodes is smaller than the diffraction limit.
Potential Applications
- High-resolution imaging devices
- Multi-spectral imaging
- Scientific research and analysis
- Medical imaging
- Surveillance and security systems
Problems Solved
- Enables capturing images in different wavelength bands simultaneously
- Increases the sensitivity and accuracy of image sensors
- Overcomes the diffraction limit for smaller meta-photodiodes
Benefits
- Improved image quality and resolution
- Enhanced ability to capture and analyze different types of light
- Compact design with smaller meta-photodiodes
- Versatile applications in various industries
Original Abstract Submitted
An image sensor may include a pixel array including a plurality of two-dimensionally arranged pixels. Each pixel may include a first meta-photodiode absorbing light of a first wavelength band; a second meta-photodiode absorbing light in a second wavelength band; and a third meta-photodiode absorbing light of a third wavelength band, wherein the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode may be arranged in an area having a size less than a diffraction limit. The arrangement form of the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode arranged in the plurality of pixels in a central portion of the pixel array may be the same as the arrangement form of the first meta-photodiode, the second meta-photodiode, and the third meta-photodiode arranged in the plurality of pixels in a periphery of the pixel array.
