Abstract
Abstract An electronic camera records files of photographed images in such a manner that files of images photographed under different photographing circumstances (e.g., different exposure modes, compression rates, or photographing dates/times) can readily be distinguished. In certain preferred embodiments, a data management index corresponding to a first photographing circumstance is recorded at a first hierarchy level and a file name assigned to an image photographed under the first photographing circumstance is recorded in association with the file management index at a hierarchy level different from the first hierarchy level. A second data management index corresponding to a second photographing circumstance or a file name assigned to an image photographed under a second photographing circumstance is also recorded at the first hierarchy level.
