Above-mentioned data file can show with image by being installed in the display monitors such as liquid crystal 18 in the video camera 1.In addition, display monitor 18 also can carry out the demonstration of thumbnail image described later.Also have, (Video I/O AudioI/O), allows the outside display equipment 21 that connects show also can to supply to the video input and output terminal to data file.Also have, also can send data file to external record device 2.Here, external record device 2 is illustrated as PC2.Between video camera 1 and PC2, can carry out wireless connections such as wired connections such as USB, IEEE1394, or IEEE802.11g, Wireless USB.Below, situation about connecting for USB between video camera 1 and the PC2 is described.
By the occasion that USB is connected, become the formation of the recording medium 17 of this video camera 1 being discerned as 1 driver from the PC2 side at video camera 1 and PC2.That is, video camera 1 is and above-mentioned USB mass memory rule-like corresponding equipment.Thereby becoming PC2 is main frame, and video camera 1 is the relation of equipment, and PC2 can carry out the reading of data file of record on the recording medium 17 of video camera 1, or recording medium 17 is carried out the rewriting and the deletion of data file.
, because can carry out rewriting, the deletion of the data file in the video camera 1 from PC2, the data file above the recording medium 17 in the video camera 1 can be deleted in duplicating sometimes by mistake.For example, as deleted reason, can enumerate the user to the restriction of the misoperation of PC2, the recording capacity deficiency that becomes the PC2 side of accepting side of photographed data, transmissible civilian number, file size, PC2 problem, connect that holding wire disconnects, the power supply disconnection of video camera 1 or PC2 etc.
Therefore, in video camera 1, be provided with and carry out the deletion of the data file above the recording medium 17, the pattern of rewriting (PC writing prohibition pattern).This pattern is by setting menu, special switch etc., sets up the pattern of sign by the mode of the deletion of the data file above the recording medium 17 that can not carry out video camera 1 and rewriting.Owing to be provided with this pattern, even the data file above the recording medium of video camera 1 17 also can be protected in the occasion that contingency is arranged.
Fig. 2 represents to have used as the preservation of data file the example of FAT (File Allocation Table) file system.In the FAT file system, be the sectors above the recording medium 17 to be summed up as the unit that calls bunch manage.Distribute 1 photographed data to 1 bunch.Data file by with this document in comprise bunch one or more several corresponding photographed data constitute.Comprise in 1 data file bunch number, promptly the number of photographed data depends on photography time.
In being called the table of FAT, for certain bunch, bunch number of next that the information that continues with photographed data of having write down is suitable.Also have and the different table that is called catalogue of FAT table.In catalogue, write down the information of bunch number of filename and front portion.Also have, in the data area,, write down all photographed data 1 photographed data of 1 bunch of distribution.1 bunch of number that 1 photographed data is distributed is called the 1st bunch of information here.
In FAT file system shown in Figure 2, write down the data file of " A ", " B ", " C "., in data file " A ", comprise photographed data " a1 ", " a2 " here, in the data file of " B ", comprised photographed data " b1 ", " b2 ", " b3 ", in the data file of " C ", comprised photographed data " c ".For example, in the occasion of sense data file " A ", obtain the information of anterior bunch number " 0 " with reference to the filename " A " of catalogue.Secondly, in FAT,, obtain the information of bunch number " 1 " of next with reference to bunch number " 0 " of this front portion.In FAT,, obtain the information of bunch number " end " of next again with reference to this bunch number " 1 "." end " means it is the last bunch number of the photographed data that comprises in this document.So the photographed data " a1 " of reading the data area corresponding with this bunch number " 0 " and " 1 " reaches " a2 ".
As mentioned above, from PC2 the recording medium 17 of this video camera 1 is discerned as 1 driver.Therefore, video camera 1 side can not be differentiated the reading to regenerating simply of data file of being undertaken by PC2 and carries out, and still carries out for duplicating.To this, PC2 is according to the indication of CPU (Central Processing Unit) 22 (Fig. 1), by bus 24 (Fig. 1), being the signal (regeneration order) that simple regeneration is read, or supplies to video camera 1 side for duplicating the signal of reading (copy command).Video camera 1 can judge whether entered the processing that indicates the data file of having read described later based on these signals.The program of supplying with these signals is by install software etc. and remember in PC2 in advance.
Fig. 3 represents from the flow chart of video camera 1 to PC2 copy data file.At first, video camera 1 is connected (Fig. 3, step S01) with PC2 by USB.Secondly, judge from the PC2 signal supplied to be copy command (Fig. 3, step S02).Be not copy command occasion (regeneration order occasion) (N), in order to regenerate and the sense data file with PC2.Thereby, can not delete the data file of having read, so do not write down the processing of bunch number from the recording medium 17 of video camera 1.Then, in order to regenerate, from the recording medium 17 sense data files (Fig. 3, step S06) of video camera 1 with PC2.What be used to regenerate reads after the end, cuts off with being connected of PC2 end process (Fig. 3, step S06).
Be the occasion (Y) of copy command in step S02, the signal processing piece 14 of video camera 1 judges whether duplicated all data files (Fig. 3, step S03).In the occasion of having duplicated all data files to PC2 (N), cut-out is connected with PC2's, finishes the recording processing (Fig. 3, step S04) of described later bunch of number.In the residual occasion of the data file of duplicating (N) to PC2, the transmission of beginning data file.The transmission of data file is undertaken by each photographed data that comprises in this document.Signal processing piece 14 is recorded in (Fig. 3, step S05) among the SDRAM19 (Fig. 1) to bunch number of the photographed data that has transmitted as the 2nd bunch of information.Then, return step S04.In addition, SDRAM19 is the tape deck of the content of temporarily holding the record that can not visit from the PC2 side.
In addition, the occasion of duplicating to PC2 data backup zone 23 (Fig. 1) at recording medium 17 from video camera 1, CPU22 in the PC2 reads the FAT above the recording medium 17 of video camera 1 and the information of catalogue, the photographed data of coming record in the copied data region (Fig. 2) according to this information.In addition, data backup zone 23 is made of HDD, semiconductor memory, DVD etc.
Fig. 4 represents to detect the flow chart that copies to the file of PC2 from video camera 1.After cutting off being connected of video camera 1 and PC2 (Fig. 3, step S05), signal processing piece 14 makes new folder (Fig. 4, step S11) in order to shift the data file that is replicated and can deletes in SDRAM19.In addition, for new folder name, can add expression deletion, duplicate information such as the thing of having finished (for example, " delete ", " copied "), the date of duplicating, the moment (for example, PC20061102_1042).
Then, judge whether bunch number (the 2nd bunch of information) (step S12) that has write down among the SDRAM19 is arranged.In the occasion (N) of bunch number that has not write down, end process.In the occasion that bunch number (Y) that has write down is arranged, read bunch number (Fig. 4, step S13) that has write down among 1 SDRAM19.
Whether secondly, judge front portion bunch number and bunch number of in step S13, having read consistent (Fig. 4, step S14) in the catalogue (Fig. 2).In the inconsistent occasion of two sides bunch number (N), bunch number of having read is finished as reading (Fig. 4, step S20), enter step S19 described later.In the occasion (Y) of two sides bunch number unanimity, obtain all bunches number (the 1st bunch of information) (Fig. 4, step S15) in the data file that comprises this bunch number according to the information of FAT.Bunch number (the 2nd bunch of information) (Fig. 4, step S16) whether all bunches number (the 1st bunch of information) in the judgment data file has write down among the SDRAM19.
In step S16, for bunch number that should comprise in 1 data file (the 1st bunch of information), in SDRAM19, only write down the occasion (N) of a part bunch number (the 2nd bunch of information), belong in the data backup zone 23 of PC2 not with form completely and finish the situation of duplicating, thereby data file is not transferred to and entered step S18 described later in the new folder.In SDRAM19, write down the occasion (Y) of all bunches numbers (the 2nd bunch of information), belong in the data backup zone 23 of PC2 with form completely and finish the situation of duplicating, thereby this data file is transferred to (Fig. 4, step S17) in the new folder that among step S11, makes from recording medium 17.Then, all bunches number (the 2nd bunch of information) (Fig. 4, step S18) in this data file of deletion from SDRAM19.By with upper type, just can discern and duplicate the data file that finishes and do not duplicate the data file that finishes.
Then, judge among the SDRAM19 whether write down bunch number (the 2nd bunch of information) (Fig. 4, step S19) that once also was not read out.In the occasion (N) of bunch number (the 2nd bunch of information) that once also was read out, end process.In the occasion (Y) of bunch number that once also was not read out (the 2nd bunch of information), return step S13, carry out same processing repeatedly.By with upper type, indicate and duplicate the data file that finishes, carry out file management.
Based on concrete example the flow chart shown in Fig. 3,4 is described here.For example, bunch number (the 2nd bunch of information) of to consider that CPU22 by PC2 reads in order duplicating, to write down among the SDRAM19 of video camera 1 is the occasion of " 0,1,2,3 ".Signal processing piece 14 is read a bunch number " 0 " from SDRAM19.With reference to catalogue, obtain a bunch number " 0 " and the anterior consistent such information of bunch number.Then, with reference to FAT, the complete bunch of number (the 1st bunch of information) of obtaining this document is " 0,1 " such information.Bunch number (the 2nd bunch of information) " 0,1 " all is recorded among the SDRAM19.Thereby the file " A " suitable with a bunch number " 0,1 " can be copied to PC2 data backup zone 23 fully.Thereby file " A " is detected as duplicating the thing that finishes, and is transferred in the new folder, and bunch number (the 2nd bunch of information) " 0,1 " is deleted from SDRAM19.
Equally, describe for remaining bunch of number " 2,3 ".Signal processing piece 14 is read a bunch number " 2 " from SDRAM19.With reference to catalogue, obtaining a bunch number " 2 " is the anterior such information of bunch number.Then, with reference to FAT, the complete bunch of number (the 1st bunch of information) of obtaining this document is " 2,3,6 " such information.Bunch number " 6 " that comprises in this bunch number " 2,3,6 " is not by the SDRAM19 record.Thereby the file " B " suitable with a bunch number " 2,3,6 " can be in the middle end process of duplicating to the data backup zone 23 of PC2.Thereby file " B " is not detected as duplicating the thing that finishes, and file " B " can not be transferred in the new folder.Then, bunch number (the 2nd bunch of information) " 2,3 " is deleted from SDRAM19.
Above-mentioned explanation is that the method for detecting in video camera 1 side is illustrated, and but, also can be to detect the formation whether data file is replicated fully in the PC2 side.In the occasion that has connected video camera 1 and PC2, PC2 reads out in the All Files size of recording medium 17 above-noted of video camera 1 in advance.From the recording medium 17 of video camera 1 after duplicate in the data backup zone 23 of PC2, relatively this file size of having duplicated and the file size of having read in advance.If both file sizes are identical, all data files have been read exactly.Then, PC2 sends video camera 1 and duplicates the signal of finishing.Having received video camera 1 side of duplicating the signal of finishing handles the data file in the recording medium 17 as duplicating the thing that finishes.
Secondly, the method for the data file that deletion has detected as duplicating the thing of having finished is described with reference to Fig. 5,6.Fig. 5 represents to delete the flow chart that duplicates the file of having finished.Fig. 6 represent to deletion duplicate till the file of having finished example of concrete picture.
