AI Technical Summary
Technical Problem
Traditional image sensors produce color images with low resolution.
Method used
The filter array employs an N-row N-column color filter group, with each filter group consisting of at least two colors. The number of target color filters in the central region is no less than the number of other color filters in the surrounding region. By swapping the positions of pixels of different colors, an electrical signal is generated.
Benefits of technology
It improves the color resolution of pixels, reduces the risk of false colors in images, and generates more realistic and delicate color effects.

Abstract
This application relates to an image sensor, an imaging module, an electronic device, an image generation method, and an apparatus. The image sensor includes a filter array and a pixel array. The filter array includes a minimum repeating unit, which in turn includes multiple filter groups. Each filter group includes at least two colors arranged in N rows and N columns, with the number of color filters corresponding to the target color in the central region of each filter group being no less than the number of color filters corresponding to other colors in the surrounding regions; where N is a natural number greater than 2; the target color is one of the at least two colors. The pixel array includes multiple pixels, with each pixel corresponding to a color filter in the filter array. The pixel array is configured to receive light passing through the filter array to generate an electrical signal. Images generated using this image sensor have better color resolution.
