An image coding device (100) which codes input image data includes a coding flag generation unit (101) which determines whether or not the input image data is image data included in data of a moving picture which shows a motion of a predetermined motion amount or greater, and generate coding flag information which indicates a result of the determination, a coding method determination unit (102) which determines such a coding method in which the input image data references coded image data that the coded image data in the case where the coding flag information generated by the coding flag generation unit indicates that the input image data is included in the data of the moving picture is closer to the input image data than otherwise, and an mage coding unit (103) which compression-codes the input image data using the coding method determined by the coding method determination unit.
