Abstract
A data coding device codes input object color pixel data into coded data. The data coding device includes a parallel/serial converter that converts the object color pixel data composed of parallel data of multiple bits into serial data, a state signal generator that generates a states signal for each bit of the serial data and a prediction device which groups each bit of the serial data based on the state signal, and an arithmetic calculator that converts the color pixel data into coded data based on the data received from the prediction device. A corresponding data decoding device is also disclosed.
