To provide a program, an information storage medium, an image processing device, an image processing method, and a data structure capable of collaboration between replay data and a motion picture produced by an image capturing unit during a period corresponding to the replay data. A replay data obtaining unit (68) obtains replay data for reproducing the status of execution of a program. A captured motion picture obtaining unit (70) obtains a captured motion picture that is produced by the image capturing unit during an image capturing period including at least a part of a reproduction period in which the status of execution of the program is reproduced based on replay data. A data holding unit (72) holds replay data and a captured motion picture so as to be correlated to each other.
