AI Technical Summary
Technical Problem
Since each pixel can only receive one color in RGB, the image sensor of the existing cameras has a loss of color information in the captured image.
Method used
A photosensitive component is designed, including at least two pixel units arranged in an array, each pixel unit includes three pixel layers, respectively for sensing light of different wavelengths and generating corresponding photosensitive signals.
Benefits of technology
The photosensitive information of at least one of the three primary colors is obtained by obtaining each pixel unit, which improves the pixel unit's perception of color and brightness, and reduces the loss of color information.
