    Abstract: A method of removing noise from image data output from an image sensor includes comparing a target block in the image data with each of at least one comparison blocks around the target block in the image data. A center pixel similarity between center pixels of the target block and each comparison block is calculated. A neighboring pixel similarity between neighboring pixels neighboring the center pixels in the target block and each comparison block is calculated. The method includes determining whether an impulsive noise exists in the center pixel of the target block based on the center pixel similarity and the neighboring pixel similarity. A weight applied to a value of the center pixel of each comparison block is adjusted based on a result of the determining. Weighted averaging is performed on values of the center pixels of the comparison blocks to estimate a value of the center pixel of the target block.

    Abstract: An image sensing system includes a pixel array, an analog-to-digital converter circuit, and a memory. The pixel array includes a first pixel, a second pixel, and a third pixel interposed between the first pixel and the second pixel. During a first sensing time, the analog-to-digital converter circuit converts a first image signal received from the first pixel to first image data and converts a second image signal received from the second pixel to second image data. During a second sensing time, the analog-to-digital converter circuit converts a third image signal received from the third pixel to third image data. The first image data and the second image data are written in the memory during a first write time, and the third image data are written in the memory during a second write time.
