An image file reproduction device for reproducing an image file from a recording medium storing an image file of a first type and/or an image file of a second type, the first type of image file being an image file which contains a header, main image data, and display-image data which is image data for display use, and stores the display-image data in an area other than an area storing the header, and the second type of image file being an image file which contains a header and main image data, and stores no display-image data in an area other than an area storing the header, the reproduction device comprising: a reproduction unit that can reproduce the first type of image file and second type of image file; a detector that detects whether each of a predetermined number of image files stored on the recording medium is the first type of image file or the second type of image file while the reproduction unit reproduces an image file; and an image file converter that converts the second type of image file to the first type of image file by reading the main image data from the second type of image file, generating display-image data based on the read main image data, and storing the generated display-image data in the original image file when the image file is detected to be the second type of image file based on the detection result, the image files of predetermined number being image files that can be reproduced when reproduction is done in the forward and/or reverse direction from the image file being reproduced.
