Abstract
In order to improve the accuracy of a code amount estimated by using a predictive residual when coding at a low data rate, an encoder is utilized to perform picture coding processing on a picture to be coded which is an input signal, by using a technique such as H.264. Specifically, a code amount predictor predicts the code amount on the basis of an evaluation value obtained by predictive-residual code amount evaluation value generating unit, a coding-condition code amount evaluation value generating unit, and a motion-vector-information code amount evaluation value generating unit. The predicted code amount is used for controlling coding in the encoder.
