System and method for classifying files in an information processing device

A digital camera, comprising:

• determining means for determining whether an image file stored on the camera was captured by the camera or was obtained from a source external to the camera;
• classifying means for classifying the image file according to information concerning the date of capture of the image file in the case that the determining means determines that the image file was captured by the camera, and for classifying the image file according to information concerning the date the image file was obtained in the case that the determining means determines that the image file was obtained from a source external to the camera;
• and
• display control means for controlling a display unit to display a result of classification performed by the classifying means,
• whereby an image file obtained from a source external to the camera is classified according to the date the image file was obtained, even though the camera receives an indication of when the image file was captured,
• the camera defines, for each image file stored in the camera, an original recorded file flag, a photographing date and time, and a correction date and time, the original recorded file flag indicating whether the image file was captured by the camera or was obtained from a source external to the camera, the photographing date and time being used to indicate a photographing date and time for the image file in the case that the image file is an image file captured by the camera, and the correction date and time being used to indicate a date and time of correction for the image file in the case that the image file is captured by the camera and corrected, and being used to indicate a date and time of obtainment for the image file in the case that the image file is obtained from a source external to the camera,
• the display control means displays a result of classification with a distinction between image files captured by the camera and image files obtained from a source external to the camera.
