A strong contrast between several near located pixels provokes the appearance of visible artifacts. Technical details. The procedure for compressing the digital images in JPG format is carried out in several stages. First, the photo is transformed into a color space YCbCr, and then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology.
The file compression ratio is in the range from to In this case, the reduction in image quality can vary from insignificant to substantial. MIME type. Main program.
