摘要： An encoding apparatus includes: an orthogonal transformation unit configured to orthogonally transform image data of a predetermined block size; a binarization unit configured to binarize the image data outputted from the orthogonal transformation unit; an arithmetic encoding unit configured to arithmetically encode the binary data generated by the binarization unit; and a prediction unit configured to predict, from the binary data, whether or not the amount of arithmetically encoded data generated by the arithmetic encoding unit exceeds a permissible maximum code amount based on a predetermined encoding standard. The encoding apparatus performs, when the prediction result is that the amount of arithmetically encoded data exceeds the maximum code amount, control to prevent the arithmetic encoding by the arithmetic encoding unit from being performed to the binary data corresponding to the prediction result.
