Image signal processor, operation method of image signal processor, and image sensor device including image signal processor

An operation method of an image signal processor, the operation method comprising:

• receiving, from an image sensor device, an input image;
• performing a binning and crop operation on the input image to generate a first image;
• generating frame information about the first input image based on the first image, wherein the frame information comprises image pyramid information about at least a portion of a first frame of the first image;
• performing Bayer domain processing on the first image to generate a second image;
• performing RGB domain processing on the second image to generate a third image;
• and
• performing YUV domain processing on the third image to generate an output image,
• wherein the performing of the YUV domain processing comprises outputting the output image,
• wherein a resolution of the second image matches a resolution of the third image, and
• 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.

An image sensor device, comprising:

• a pixel array comprising a plurality of pixels;
• a row driver configured to control the plurality of pixels;
• an analog-to-digital converter configured to convert pixel signals into digital signals;
• an output buffer configured to output an input image based on the digital signals;
• and
• an image signal processor configured to generate an output image based on the input image,
• wherein the image signal processor is further configured to:
• generate first frame information based on the input image;
• perform a binning and crop operation on the input image to generate a first image;
• generate second frame information about the first input image based on the first image, wherein the second frame information comprises image pyramid information about at least a portion of a first frame of the first image;
• perform Bayer domain processing on the first image based on the first frame information to generate a second image;
• perform RGB domain processing on the second image based on the first frame information to generate a third image;
• and
• perform YUV domain processing on the third image based on the first frame information to generate the 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.
