- the acquisition source of the image file in the recording data may be a plurality of (photographing devices), and when inputting each recording data to the PC 10, the image file of each recording data Even if the file names are different, when an image file is recorded on a blank electronic album disc 30, there is a possibility that the image file with the same file name will be recorded. Therefore, before recording the image file on the electronic album disc 30, the original file name is renamed to a highly unique file name by the process described below. Then, the image file with the renamed file name is recorded on a blank electronic album disc 30.
- the recording data may be acquired for each original directory.
- a directory with the same directory name may be recorded.
- the original directory name may be renamed to a highly unique directory name by the process described below.
- a directory having the renamed directory name is formed and recorded in the electronic album disc 30 of the image file blank in the directory.
- the PC 10 when an instruction to record a predetermined image file is given via the operation unit 12 and a file name or directory name of the image data is generated (renamed), the PC 10 appropriately reads it from the HDD 15 and expands it in the RAM 13.
- the code assigning process is executed in cooperation with the code assigning program and the CPU 11. This execution start procedure is the same in each process described later.
- step Sl l it is determined whether or not a force has acquired a code having the number of digits necessary to enhance uniqueness. If the code of the required number of digits has not been acquired (step SI 1; NO), it is determined whether or not to acquire a seed (step S 12). When obtaining a seed (step S12; YES), one seed is obtained (step S13). A seed is information used to generate a unique code.
- the code assignment target is an image file (file name), at least a data string in the image file and a file size are used as seeds.
- the target of code assignment is a directory (directory name)
- at least the data string in the image file, the file size of the image file in the directory, and the number of image files in the directory are used as seeds.
- Other seeds include, for example, time information, ascending or descending permutation, author's profile information (name, address, date of birth, etc.), serial number recorded on a recording medium such as electronic album disc 30, electronic album disc Recording medium identification information (disc ID) for identifying recording media such as 30, arbitrary file selection information, the above data string selection information, valid data extraction information, seed selection information, encoding of the above permutations, etc. Selection information, pseudo-random numbers, etc.
- the time information includes shooting time information included in Exif (Exchangeable Image File Format) information of the image file, current time information timed by the timekeeping section 1A (recording of the image file to the electronic album disc 30). Time information).
- Typical pseudo-random number generation methods include (l) Mersenn e Twister, (2) M series, (3) linear congruential method, (4) squaring method, etc. in descending order of uniformity. Each has the same computation time, and the linear congruence method uses different random number seeds (used to generate pseudo-random numbers). information. In this case, the same number sequence may be output even if “random seed” is selected to distinguish it from the seed for generating the code.
- the squaring method has the disadvantage that it can only be used when taking even digits. Therefore, it is preferable to use Mersenne Twister, M series.
- the acquired seed is combined with the already acquired seed (step S14), and the process proceeds to step S12. If only one seed is obtained, do not combine.
- the combination is, for example, the sum (addition) or multiplication of character strings of codes.
- step S12 If the seed is not newly acquired (step S12; NO), the radix of the code obtained from the acquired seed is converted (step S15). Then, the number of digits with low uniqueness is discarded from the code whose base number has been converted (step S16), and the process proceeds to step S11. For example, in the case of date / time information at the time of recording, digits corresponding only to year / month / date / time may be digits that have low uniqueness and may overlap.
- step S11 When a code having the required number of digits is acquired (step S11; YES), the digit powers of the acquired codes are rearranged (step S17). Then, the rearranged code strength is assigned to the file name of the image file to be renamed or the directory name of the directory (step S17), and the code assignment processing is terminated.
- seed (code) processing includes decimal conversion, truncation of less unique digits, rearrangement of digits, pseudorandom number generation using seed (code), and division of seed by an arbitrary number. You may include making it a remainder.
- the seeds are processed after being combined, but they can be combined after the seeds are covered! /.
- the generated file having a unique file name and the directory (structure) having a unique directory name are recorded on the electronic album disc 30.
- a data string acquisition process is executed (step S21).
- the first data string acquisition process as an example of the data string acquisition process will be described with reference to FIG.
- the properties of the image file are referred to, and the file size of the image file is acquired (step S31).
- the image file is opened (step S32).
- seek is performed at a position of 50% of the file size acquired in step S31 in the opened image file (step S33). In other words, it seeks 50% from the beginning of the digital data of the image file.
- 2 bytes of the data string is read as a seed from the seek position of the image file (step S34).
- the image file is closed (step S35), and the first data string acquisition process is ended.
- the acquired data string is processed (step S22).
- the data string processing includes, for example, conversion of a decimal number to the data string, truncation or rearrangement of digits with low uniqueness.
- a file name including the processed data is generated and given to the image file to be renamed (step S23), and the first file name generation process is terminated. All or part of the character string included in the original file name may or may not be left.
- the seek position of the data string and the length of the data string are not limited to this example.
- common data is recorded at the beginning and end of the image file!
- FIG. 7 shows an example of a histogram of the number of image files with respect to digital values of a data string when a seek position is 50% of the file size and a 1-byte data string is acquired.
- Fig. 7 shows 358 directories before renaming registered in the electronic album and 17924 JPEG and DCF formats stored in that directory are shown.
- a formula image file is used.
- Sample image file images include general photos (negative digitized images, images taken with a digital still camera), and ID photos taken with a video camera. This sample is used in the same way for the histograms of FIGS. 12, 13 and 17 described later.
- the digital value of the data string of the image file has a peak at 128, etc. Since the others are distributed almost uniformly, the digital value is highly unique. Furthermore, the uniqueness increases as the number of bytes in the data string increases. If n (n: any natural number) bytes are acquired, 256 n combinations of data can be acquired, and the number of bytes that can be acquired is equivalent to the file size, so it can be said to be almost infinite.
- the acquisition time of the data string is longer than the acquisition time of other seeds because the image file needs to be opened.
- the time to acquire 1 byte of the data string is about 25% of the time required to copy the image file, and an average of about 50 image files are stored in one directory. Therefore, the time to acquire the data string for one image file in the directory is about 0.5% of the entire directory creation time including the copy of the image file, and there is almost no influence.
- Step S42 after the image power is opened, it is determined whether or not the number of bytes of the acquired data string is a predetermined value (desired number of acquired bytes) (Ste S43). If the acquired number of bytes is smaller than the specified value (step S43; NO), the file is sought to the position of the unseek ratio of the file size acquired in step S41 in the opened image file (step S44). . For example, it seeks to an unseeked position such as 50% from the beginning of the digital data of the image file.
- Step S45 1 byte of the data string is read as a seed from the seek position of the image file (step S45), and the process proceeds to step S43. If the acquired number of bytes is a predetermined value (Step S 43; YES), the process proceeds to step S46.
- step S51 the properties of all the image files in the directory to be renamed are referred to acquire each file size. Then, when the file sizes of the image files in the directory are arranged in ascending order, the image file having the file size closest to 50% is selected (step S52). However, other predetermined ratios other than those limited to 50% may be used.
- Step S53 a data string acquisition process similar to step S21 of Fig. 5 is executed on the selected image file (step S53).
- Step S54 is the same as step S22 in FIG.
- a directory name including the processed data string is generated and given to the directory to be renamed (step S55), and the first directory name generation process is terminated.
- one image file is selected in a predetermined ratio in the file size order, but the present invention is not limited to this.
- a configuration in which a predetermined ratio of image files is selected in the order of file names may be employed.
- a predetermined plurality of image files are selected and acquired (step S61). For example, out of all image files in the directory to be renamed, in a predetermined order (for example, 30%, 50%, 70%, etc.) A plurality of predetermined image files in the corresponding order) are selected.
- the predetermined ratio and the number of selected image files may be calculated by generating pseudo-random numbers using random number seeds such as time information.
- step S62 it is determined whether or not there is an unselected image file among the plurality of acquired image files. If there is an unselected image file (step S62; YES), one unselected image file is selected (step S63).
- Step S64 a data string acquisition process similar to step S21 in FIG. 5 is executed for the selected image file (step S64). Then, the acquired data string and the already processed data string are combined in the same manner as in step S14 in FIG. 4 (step S65). The combined data string is not cached as in step S22 of FIG. (Step S66), the process proceeds to Step S62. If there is no unselected image file (step S62; NO), a directory name containing the processed data string string is generated and given to the directory to be renamed (step S67), and the second directory The name generation process is terminated.
- step S71 the property of the image file to be renamed is referred to, and the file size of the image file is acquired (step S71). Then, the obtained file size is processed in the same manner as step S22 in FIG. 5 (step S72). Processing includes processing such as using the last 1 to 4 digits of the file size of the image file described later. Then, a file name including the processed file size is generated and given to the image file to be renamed (step S73), and the second file name generation process is terminated.
- FIG. 12 shows a histogram of the number of image files against the file size of an image file that has been digitized with the same device, JPEG compressed image file, and JPEG compressed image file taken with the same video camera.
- Most of the image files at this peak are digitized old negatives with film scanners.
- about 7000 ID photos occupy image files concentrated around 15k bytes. In this way, it can be seen that the occurrence probability is not uniform despite the large range of 4 to 7 decimal digits.
- the appearance probability is uniform although the combination is reduced. Get closer to. For example, in Fig. 13, the probability of occurrence is almost uniform in the histogram of the number of image files for the last two digits of the file size. Thus, the file size is 10 If you use n (n: any natural number) digits in decimal, you can get a code of 10 "combination.
- Step S81 and S82 of the third directory name generation process are the same as steps S51 and S52 of FIG. Then, the property of the selected image file is referred to in step S82, and the file size is obtained (step S83).
- Step S84 is the same as step S72 in FIG. Then, a directory name including the file size checked in step S84 is generated and given to the rename target directory (step S73), and the third directory name generation process is terminated.
- Step S91, S92, and S93i of the fourth directory name generation process are the same as steps S61, S62, and S63 of FIG.
- the file size is acquired for the image file selected in step S93 in the same manner as in step S83 in FIG. 14 (step S94).
- the acquired file size, the already processed file size and the force are combined in the same manner as in step S14 in FIG. 4 (step S95).
- the combined file size is processed in the same manner as in step S72 in FIG. 11 (step S96), and the process proceeds to step S92. If there is no unselected image file (step S92; NO), a directory name including the processed file combination is generated and given to the rename target directory (step S97), and the fourth directory name generation process Is terminated.
- step S101 the number of files of all files in the rename target directory is obtained. Then, the obtained number of files is processed in the same manner as in step S22 in FIG. 5 (step S102). Then, a file name including the number of processed files is generated and given to the image file to be renamed (step S 10 3) The second file name generation process is terminated.
- FIG. 17 shows a histogram of the number of directories with respect to the number of files in the directory.
- 1 to 50 of the forces that had 1 to 688 files in the directory were taken as samples.
- this histogram there are peaks around 24 and 36 corresponding to one lot of film.
- the power of reducing the combination will appear uniform.
- a value with a high probability of overlap is a value with high frequency in each histogram.
- the digital values of the data string are 10, 12, 3 4, 45, 128, 148, 168, 197, 201, 242.
- the file size is 510639 to 510673.
- the number of files is 25,36.
- a blacklist value when a blacklist value is obtained, it is assigned to a value that is not in the blacklist.
- the blacklist value is acquired, the acquired value is converted using information obtained from other information sources.
- a part of the acquired value (unique, part is preferred, eg, upper digit part) may be removed.
- a second coping method there is a high probability of overlapping as seed information, and a value is obtained by excluding a part. For example, when acquiring a data string of an image file, as described above, values are acquired avoiding the vicinity of the top and end of the image file.
- a third coping method is to obtain a partial force value with a low probability of overlapping as seed information.
- the probability of duplication is low, and it is preferable to combine time information (especially milliseconds) with the file size (or data string). Or you can use this time information It is preferable to check the size (or data string). Also, if batting is unavoidable, such as when time information cannot be obtained to the millisecond level, a permutation (increment value may be fixed or random) is added to each image file.
- a fourth coping method is to generate code by acquiring other information and replacing it with information that cannot be acquired if there is information that cannot be acquired as seed information. For example, when combining the file size (or data string) of an image file with time information, if the time information cannot be obtained up to milliseconds, the data string (or file size) or a value obtained by processing them is obtained as other information. And combine.
- the fifth coping method is to generate a code excluding a portion where the information power acquired as seed information has a high probability of duplication. For example, when combining the file size (or data string) of an image file with time information, the time information is acquired to the minute, second, and millisecond unit. The unit part of the date and time of the time information may be replaced with the above other information.
- a sixth coping method is to check the acquired seed information when acquiring the copied image file power seed information. For example, the file size (or data string) of the copied image file is acquired, and the permutation information is added to the information to carry out a check.
- a unique code is generated from at least one of the data string and file size in the original image file as a seed, and the file name including the code is generated. Since it is generated and assigned, the uniqueness of the file name can be sufficiently enhanced.
- a unique code is generated from at least one of a data string, a file size, and the number of files in at least one original image file in the directory as a seed. Since the directory name including the code is generated, the uniqueness of the directory name can be sufficiently enhanced.
- the information amount of the code can be reduced, and the information amount of the file name or the directory name can be reduced.
- rearrangement of seed digit as processing of acquired seed in addition, by adding a permutation to the seed, the uniqueness of the code can be enhanced, and the uniqueness of the file name or directory name can be enhanced.
- FIG. 18 illustrates the third file name generation process. Since the apparatus configuration of this modification is the same as that of the above embodiment, the description thereof is omitted.
- the third file name generation process is a process for generating a code by combining time information and a data string in an image file, and generating a file name of an image file including the code.
- the current date and time information is acquired by the time measuring unit 1A (step S111). Then, the acquired time information is converted to 1Z100 seconds in units of 10:00 am 0:00 am, 00 seconds force, and current time information (step S112). Then, the converted elapsed time is converted into a 36-digit number (step S113).
- Steps S114 and S115 are the same as steps S71 and 72 of FIG.
- Step S1 16 is the same as step S21 in FIG.
- the data string acquired in step S116 is converted into a 36-digit number (step S117).
- the elapsed time after conversion is assigned to the upper 5 digits of the code
- the lower power of the converted data string is also assigned to the lower 3 digits of the code in order
- a file name including the code is generated (step S118). ),
- the third file name generation process is terminated.
- the time information is measured to the millisecond unit of the year / month / day / hour / minute / second. For example, assuming that 10 ⁇ ⁇ ( ⁇ : any natural number) seconds can be acquired, data of a combination of 8400 * 1 0 ⁇ ⁇ can be acquired.
- the time zone for generating file names and directory names may be biased because it is small in the early morning. If it is obtained by using GMT (Greenwich Mean Time: Universal Time of Coordinated) It is considered that the probability of occurrence approaches uniformly. However, even with GMT, time information may be duplicated in the neighborhood, and image files and directories are likely to be exchanged.
- the data sequence of the image file and the time information are used as seeds, and the code including the time information is further processed and set at the beginning of the file name.
- the file name can be easily sorted in the order of the processed time information, and the user can easily confirm the file name visually.
