1. An image signal apparatus, comprising:
a memory storage; and
an image signal processor communicatively coupled to the memory storage, wherein the image signal processor is configured to cause the image signal apparatus to:
receive, from a first image sensor device, a first input image;
perform a binning and crop operation on the first input image to generate a first image;
generate first frame information about the first input image based on the first image, wherein the first frame information comprises image pyramid information about at least a portion of a first frame of the first image;
perform a Bayer domain processing on the first image to generate a second image;
perform RGB domain processing on the second image to generate a third image; and
perform YUV domain processing on the third image to generate an output image,
wherein the YUV domain processing comprises at least one of a spatial de-noising operation, a temporal de-noising operation, a motion compensation operation, a tone mapping operation, a detail enhance operation, and a sharpening operation.
