The objective of the invention is to provide an image reproduction device that can take digital data that has been subjected to analog conversion and reproduce digital data therefrom that is substantially the same as the original digital data, without using over-sampling or special hardware.An analog signal that was generated as a digital signal by an image generation device (200), but then subjected to analog conversion, and a synchronization signal from the image generation device (200) are input to an image reproduction device (100). A clock generation section (30) generates a sampling clock which has the same frequency as the dot clock used during the digital data generation, and with a suitably-adjusted phase, based on an input horizontal synchronization signal (12) together with frequency data (82) and phase data (84) as selected by a selection section (80). Digital data is reproduced from the input analog signal by an analog-digital converter (40), based on the thus generated sampling clock.
