Abstract: An encoding system includes a prediction mode decision unit and an encoding unit. The prediction mode decision unit is configured to receive a target image and decide an optimized mode by applying rate-distortion optimization (RDO) to n (n is a natural number) modes of the target image. The encoding unit is configured to encode the target image according to the decided mode. The prediction mode decision unit includes a distortion calculation unit configured to calculate distortion by mean squared error (MSE) calculation between the target image and the n modes, a Lagrangian multiplier calculation unit configured to calculate a Lagrangian multiplier based on multi-scale structural similarity (MS-SSIM) calculation, and a bitrate calculation unit configured to calculate a bit rate of the n modes.

Abstract: A method of encoding data includes selecting a line to define an adjustment target coefficient group in each of a plurality of coefficient groups included in a transform unit that has been transformed and quantized. Each of the coefficient groups comprises a plurality of coefficients. For each of the coefficient groups, a sum of the coefficients for the respective coefficient group is calculated. For each of the coefficient groups, a value of one adjustment target coefficient included in the adjustment target coefficient group is adjusted according to a result of the calculation of the sum of the coefficients for the respective coefficient group.
