摘要： A coding apparatus includes a predicting unit, an intermediate-code generating unit, a first coding unit and a second coding unit. The predicting unit generates a piece of prediction data based on each piece of pixel data constituting a color image. The intermediate-code generating unit compares each piece of prediction data with the corresponding piece of pixel data, to generate an intermediate code in accordance with whether or not a difference between each piece of prediction data and the corresponding piece of pixel data is in a predetermined range. The first coding unit performs entropy coding on the generated intermediate code. The second coding unit performs entropy coding on the generated intermediate code. The intermediate-code generating unit assigns each generated intermediate code to either of the first and second coding units according to whether or not the difference is in the predetermined range.

摘要： An encoder includes a prediction unit and a code generation unit. The prediction unit predicts target data and judges whether prediction is right or wrong. When the prediction unit judges that consecutive predictions for respective target data are wrong, the code generation unit generates coded data including symbols corresponding to the respective target data for which the consecutive wrong predictions are made, using a code representing number of the consecutive predictions judged as wrong.
