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

Abstract

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.

 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 said attribute data file matches the attribute information read through said 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 said recording processing based upon results of the decision made in said decision-making processing.   
   
   
       2 . A recording medium according to  claim 1 , wherein
 in said control processing, a recording operation through said recording processing is allowed when said non-match signal is output through said decision-making processing and a recording operation through said recording processing is disallowed when said match signal is output through said decision-making processing.   
   
   
       3 . A recording medium according to  claim 2 , wherein
 in said attribute data file creation processing, said attribute information of the information data file having been recorded through said recording processing is recorded in said attribute data file when the recording operation is allowed through said control processing.   
   
   
       4 . A recording medium according to  claim 1 , wherein
 said attribute data file is held over a predetermined length of time.

 specification processing in which at least one type of attribute information in said attribute information is specified; and   decision-making processing in which a decision is made as to whether or not the attribute information specified through said specification processing matches the attribute information read through said read processing, a match signal is output when matching and a non-match signal is output when not-matching, wherein   in said control processing, said recording processing is controlled so as to allow a recording operation through said recording processing when said match signal is output through said decision-making processing and disallow a recording operation through said recording processing when said non-match signal is output through said decision-making processing.   
   
   
       6 . A recording medium having a data file management program recorded therein, said program comprising:
 recording processing in which an information data file is recorded in a recording medium;   read processing in which attribute information of at least two information data files that have not yet been recorded in the recording medium is read;   decision-making processing in which a decision is made as to whether or not there is specific continuity in said information data files based upon the attribute information read through said read processing; and   file management processing in which said information data files are managed to be grouped based upon results of said decision made through said decision-making processing.   
   
   
       7 . A recording medium according to  claim 6 , wherein:
 in said decision-making processing, a decision is made as to whether or not specific continuity manifests with regard to time points at which the information data files were created; and   in said file management processing, said information data files are managed as information data files in a single group when said continuity is determined to manifest through said decision-making processing.   
   
   
       8 . A recording medium according to  claim 1 , wherein
 said information data file that has not yet been recorded in the recording medium is already recorded in an electronic camera or in a computer apparatus.   
   
   
       9 . A data file management apparatus comprising:
 a recording device that records an information data file in a recording medium;   an attribute data file creation device that creates an attribute data file having recorded therein attribute information of the information data file recorded in the recording medium;   a read device that reads attribute information of an information data file which has not yet been recorded in the recording medium;   a decision-making circuit that makes a decision as to whether or not said attribute information recorded in said attribute data file matches the attribute information read by said read device, outputs a match signal when matching and outputs a non-match signal when not-matching; and   a control circuit that controls said recording device based upon results of the decision made by said decision-making circuit.   
   
   
       10 . A data file management apparatus comprising:
 a recording device that records an information data file in a recording medium;   a read device that reads attribute information of at least two information data files which have not yet been recorded in the recording medium;   a decision-making circuit that makes a decision as to whether or not specific continuity manifests in the information data files based upon the attribute information read by said read device; and   a file management circuit that implements grouping management on the information data files based upon results of the decision made by said decision-making circuit.   
   
   
       11 . A recording medium having a data file management program recorded therein, said program comprising:
