Abstract

An image encoding device configured to perform prediction for a received image for each block on the basis of encoded pixels to generate prediction errors, a transform and quantization unit configured to perform orthogonal transform and quantization on the prediction errors to generate quantization coefficients, a coefficient encoding unit configured to encode the quantization coefficients, an arithmetic precision information generating unit configured to generate arithmetic precision selection information representing selection of arithmetic precision of at least one of the prediction, the orthogonal transform, and the quantization, and an arithmetic precision encoding unit configured to encode the arithmetic precision selection information.
