IMAGE SENSOR, APPLICATION PROCESSOR AND IMAGE SENSING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18050270 titled 'IMAGE SENSOR, APPLICATION PROCESSOR AND IMAGE SENSING DEVICE
Simplified Explanation
The patent application describes an image sensor that includes a pixel array with normal pixels, phase detection groups, and a color filter array. Each phase detection group consists of two adjacent phase detection pixels. The color filter array is made up of unit groups, each containing color filters of the same color arranged in an M×N matrix on the pixel array.
- The image sensor includes normal pixels, phase detection groups, and a color filter array.
- Each phase detection group consists of two adjacent phase detection pixels.
- The color filter array is made up of unit groups, each containing color filters of the same color arranged in an M×N matrix.
- The first phase detection pixel in one unit group has a color filter of the first color, while the second phase detection pixel in another unit group has a color filter of the second color.
Potential applications of this technology:
- Digital cameras
- Smartphone cameras
- Surveillance cameras
- Medical imaging devices
Problems solved by this technology:
- Improved phase detection autofocus accuracy
- Enhanced color filtering for better image quality
Benefits of this technology:
- Higher accuracy in autofocus functionality
- Improved image quality with better color filtering
Original Abstract Submitted
An image sensor includes a pixel array including a plurality of normal pixels, a plurality of phase detection groups, and a color filter array. Each phase detection group includes a first phase detection pixel and a second phase detection pixel disposed adjacent to the first phase detection pixel. The color filter array includes a plurality of unit groups. Each unit group includes a plurality of color filters of a same color arranged in an M×N matrix on the pixel array, wherein M and N are natural numbers. A first color filter among the color filters of a first color is disposed on the first phase detection pixel of one of the unit groups and a second color filter among the color filters of a second color different from the first color is disposed on the second phase detection pixel of another one of the unit groups.
