Recording medium for data file management, apparatus for data file management, handling apparatus for image data, and image capturing system


When a shutter release operation is performed at an electronic still camera, an MPU records image data output from an image capturing element into a CF card. The MPU also stores the image data in a transfer buffer memory of an interface circuit. The image data stored in the transfer buffer memory are transferred to a transfer buffer memory provided at an interface circuit of a personal computer connected via an IEEE-1394 cable. The MPU of the personal computer reads out the image data having been taken into the personal computer from the transfer buffer memory and records them in a specific recording area in a recording device.

An object of the present invention is to provide a recording medium for data file management that is utilized to record image data obtained by capturing images in an electronic camera into a data recording device, an apparatus for data file management, a handling apparatus for image data and an image capturing system.

In order to achieve the object described above, a recording medium according to the present invention has a data file management program recorded therein, and the program comprises: recording processing in which an information data file is recorded in a recording medium; attribute data file creation processing in which an attribute data file having recorded therein attribute information of the information data file recorded in the recording medium is created; read processing in which attribute information of an information data file that has not yet been recorded in the recording medium is read; decision-making processing in which a decision is made as to whether or not the attribute information recorded in the attribute data file matches the attribute information read through the read processing, a match signal is output when matching and a non-match signal is output when not-matching; and control processing in which control is implemented on the recording processing based upon results of the decision made in the decision-making processing.

In the control processing, a recording operation through the recording processing may be allowed when the non-match signal is output through the decision-making processing and a recording operation through the recording processing may be disallowed when the match signal is output through the decision-making processing.

In the attribute data file creation processing, the attribute information of the information data file having been recorded through the recording processing may be recorded in the attribute data file when the recording operation is allowed through the control processing.

The attribute data file may be held over a predetermined length of time.

The program recorded in the above recording medium may further comprise: specification processing in which at least one type of attribute information in the attribute information is specified; and decision-making processing in which a decision is made as to whether or not the attribute information specified through the specification processing matches the attribute information read through the read processing, a match signal is output when matching and a non-match signal is output when not-matching, and in the control processing, the recording processing may be controlled so as to allow a recording operation through the recording processing when the match signal is output through the decision-making processing and disallow a recording operation through the recording processing when the non-match signal is output through the decision-making processing.
