Polarizing and Color Pixel Grid Arrangement for Image Sensor Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solid-state image capturing devices that arrange polarizing pixels instead of color pixels suffer from decreased detection accuracy for color information and limited accuracy for polarization information, particularly due to the thinning of color pixels and suboptimal arrangement of polarizing pixels.
Innovation Solution
A solid-state image capturing device with a pixel array unit that includes polarizing pixels and color pixels arranged in a grid form, where color pixels are positioned between adjacent polarizing pixels, allowing for improved detection accuracy by optimizing the arrangement and size of both pixel types, including different shapes and transmission axes, and separate signal lines for each type of pixel.

1Device complexity
If only one polarizing pixel is arranged for four pixels, then device complexity is reduced, but polarization information detection accuracy has room for improvement
Solution Approach 1:
Different regions of the pixel array are assigned different functions with optimized characteristics. Polarizing pixels are arranged in grid patterns with specific transmission axis orientations (0°, 45°, 90°, 135°) to maximize polarization detection accuracy in each local region, while maintaining overall system manageability.
