FIELD: information technology.SUBSTANCE: disclosed is obtaining as a bitrate error, the difference between a selected bitrate and the actual generated bitrate of an encoded image, wherein for a plurality of subsequent images, the selected allowable correction range is either a maximum value or a minimum value of the selected bitrate based on the bitrate error sign, wherein the maximum value and the minimum value of the selected bitrate are calculated based on the initial value of the selected bitrate and a predetermined constant, wherein for a plurality of images, the allowable bitrate is obtained as the deviations of the difference between the allowable correction range and the selected bitrate, wherein the updating value is the ratio of the ratio of the sum of allowable bitrate deviations to the bitrate error, wherein the bitrate deviation for the selected bitrate is calculated for the plurality of images based on the allowable bitrate deviation and the updating value, and wherein the selected bitrate for each of the plurality of images is updated based on the bitrate deviation.EFFECT: improved image quality due to reduced deviation of image quality between images when encoding video with a target bitrate.11 cl, 16 dwg |
