摘要： PROBLEM TO BE SOLVED: To prevent the coding efficiency from deteriorating when the moving image coded string obtained by encoding interlaced signals is reencoded, and that reduces an amount of computation required for the conversion. SOLUTION: A decoder generates a decoded image and a coding parameter from a first moving image coded string. A coding parameter converter first sets the coding structure for a pair of upper and lower macro blocks based on the coding structures of the corresponding macro blocks and converts the remaining parameters such as a motion vector based on the coding structure. A coding parameter generator generates coding parameters of an intraframe coding parameter, etc., a coding parameter selector selects an optimum parameter, and a coder performs recoding processing.

摘要： PROBLEM TO BE SOLVED: To encode a moving image by selecting a prediction mode having high encoding efficiency and less deterioration in picture quality from a plurality of prediction modes. SOLUTION: Prediction residual signals generated by an inter-prediction device 102 and an intra-prediction device 103 in each prediction mode are inputted to a mode judgment device 104. The mode judgment device 104 generates orthogonal transform coefficients by orthogonally transforming the inputted prediction residual signals. Then the mode judgment device 104 counts the number of coefficients which are turned to non-zero by quantizing processing out of the orthogonal transform coefficients of the prediction residual signals in each prediction mode and selects the prediction mode having the smallest number of non-zero coefficients. The prediction residual signals corresponding to the prediction mode selected by the mode judgment device 104 are orthogonally transformed by an orthogonal transformer 105, quantized by a quantizer 106 and outputted from an entropy encoder 111 as encoded data.
