Image sensor with auto-focus and color ratio cross-talk comparison
An electronic device includes an image sensor, a memory, and a processor operably connected to the image sensor and the memory. A pixel array in the image sensor includes at least one pixel that is configured as an auto-focus pixel that is at least partially shielded from light by a shielding element. The memory stores computer-readable instructions, and the processor is adapted to produce a digital image by executing the computer-readable instructions for obtaining a plurality of coefficients representing a relationship between a ratio of two affected pixels and a ratio of two non-affected pixels in the pixel array, constructing a predictive function based on the plurality of coefficients, and computing a compensated pixel value for at least one pixel of the image sensor using the predictive function. A digital image can be created based in part on the compensated pixel value.
