The image encoding device of the present invention is an image encoding device that encodes a still image and a moving image, the device including: a determination unit that determines a first upper limit and a second upper limit, the first upper limit indicating an upper limit of the amount of code per picture of still images, and the second upper limit indicating an upper limit of the amount ofcode per picture in a moving image; an encoding unit that encodes each of the still images and the moving image in such a manner that the first and second upper limits are satisfied; a multiplexing unit that generates a stream by multiplexing the encoded still images and the encoded moving image; a generation unit that generates management information that identifies the first and second upper limits; and an output unit that outputs the stream and the management information.
