1. A camera comprising: first means for repetitively capturing an image of a subject and generating captured-image data representing the captured image of the subject; a first recording medium; second means for recording the captured-image data generated by the first means on one or more of clusters of unit recording areas in the first recording medium, wherein first cluster information pieces are assigned to the clusters respectively; third means for managing said one or more of the clusters as one data file including the captured-image data recorded on said one or more of the clusters by the second means; fourth means for receiving a control signal from an external recording device; fifth means for deciding whether or not the control signal received by the fourth means is a copying command indicative of a requested data file; sixth means for reading captured-image data in the requested data file from one or more clusters in the first recording medium and sending the read captured-image data toward the external recording device when the fifth means decides that the control signal is the copying command; a second recording medium; seventh means for detecting a first cluster information piece or pieces assigned to said one or more clusters from which the sixth means reads the captured-image data; eighth means for recording the first cluster information piece or pieces detected by the seventh means on the second recording medium as a second cluster information piece or pieces; ninth means for detecting a first cluster information piece or pieces assigned to one or more clusters loaded with captured-image data in the requested data file; tenth means for deciding whether or not the first cluster information piece or pieces detected by the ninth means are the same as the second cluster information piece or pieces; eleventh means for recognizing the requested data file as a data file which has been copied only when the tenth means decides that the first cluster information piece or pieces detected by the ninth means are the same as the second cluster information piece or pieces; and twelfth means for discriminating a data file which has been copied and a data file which has not been copied yet from each other in response to the recognizing by the eleventh means.
