IMAGE SENSOR INCLUDING AN AUTO-FOCUS PIXEL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18513747 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.
