Document Type and Number:
Japanese Patent JP4618436
Kind Code:
B2
Abstract:
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.
