IMAGE SENSOR INCLUDING AN AUTO-FOCUS PIXEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240098384 titled 'IMAGE SENSOR INCLUDING AN AUTO-FOCUS PIXEL
Simplified Explanation
The patent application describes an image sensor with a pixel array divided into first and second pixel groups, each containing rows and columns of pixels. The sensor includes a row driver that controls the transmission of signals to the pixel array. The first pixel group contains a first auto-focus (AF) pixel with photodiodes arranged in a specific direction, while the second pixel group contains a second AF pixel with photodiodes arranged perpendicular to the first direction. Both AF pixels receive the same transmission control signals.
- Pixel array divided into first and second pixel groups
- Row driver controls signal transmission to pixel array
- First pixel group contains first AF pixel with photodiodes in one direction
- Second pixel group contains second AF pixel with photodiodes in perpendicular direction
- Both AF pixels receive same transmission control signals
