Mosaic also refers to a widely used image (video) processing method, which worsens the color scale details in a specific area of the image and causes the color blocks to be disrupted. Because this blur seems to be composed of small squares, it is vividly called mosaic. Its purpose is usually to make it unrecognizable. Have we all heard of "Close-up"?
