    • A method of reproducing an image file from a recording medium that stores an image file of a first type and/or an image file of a second type includes reproducing the first type of image file or second type of image file, detecting 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 during the reproduction of an image file, and converting 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 (image data for display use) based on the read main image data, and storing the generated display-image data in the original image file if the image file is determined to be the second type of image file based on the detection result. The first type of image file is an image file containing a header, main image data, and display-image data, and storing the display-image data in an area other than an area storing the header. The second type of image file is an image file containing a header and main image data, and storing no display-image data in an area other than an area storing the header. 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.
    • 从存储第一类型的图像文件和/或第二类型的图像文件的记录介质再现图像文件的方法包括再现第一类型的图像文件或第二类型的图像文件,检测每个图像文件 存储在记录介质上的预定数量的图像文件是在图像文件再现期间的第一类型的图像文件或第二类型的图像文件,并且通过读取第二类型的图像文件到第一类型的图像文件 来自第二类型的图像文件的主图像数据,基于读取的主图像数据产生显示图像数据(用于显示使用的图像数据),并且如果确定了图像文件,则将生成的显示图像数据存储在原始图像文件中 作为基于检测结果的第二类图像文件。 第一类图像文件是包含标题,主图像数据和显示图像数据的图像文件,并且将显示图像数据存储在除了存储头部的区域之外的区域中。 第二类型的图像文件是包含标题和主图像数据的图像文件,并且在除了存储头部的区域之外的区域中不存储显示图像数据。 预定数量的图像文件是当正在再现的图像文件沿正向和/或相反方向进行再现时可以再现的图像文件。
