Abstract
An image coding device in which entropy coding is applied to binarized data. An image coding unit codes image data; an entropy coding unit binarizes the coded image data and applies entropy coding to the binarized data; and a coding amount prediction unit obtains a predictive value corresponding to a coding amount of the image data on a predetermined data unit basis prior to the actual binarizing. A coding amount comparing unit compares the predictive value to a predetermined threshold value; a I_PCM decision unit outputs a selection signal indicating the image data on a predetermined data unit basis or I_PCM data, which is selected based on a result of the comparing; and an output selection unit and an output unit output the selected data indicated by the selection signal.
