Description

  The present invention relates to a recording apparatus that records in a file with a file name generated using the current time, a recording apparatus using the recording apparatus, a program that causes a computer to function as each unit in the recording apparatus, and the recording apparatus It relates to a recording method.

  2. Description of the Related Art Conventionally, there has been known a device having a calendar and a clock function and generating a file name of a file used for data recording from a recording date and time. As such a device, for example, a recorder or a digital camera for recording a meeting or the like is applicable. As the file name to be generated, for example, when the time when the recording start instruction is given is 12:34:56 on January 23, 2008, the file name “2008013123456.MP3” can be generated. In this example, they are year, month, day, hour, minute, second, and extension. In this example, the extension is that of the MP3 file.

  In such a device, when a file having the generated file name already exists, the following operation (1) to (3) is performed. That is, a message such as (1) “Do you want to overwrite” is displayed and the user is asked to select whether or not to overwrite. (2) Overwrite without displaying a message. Or (3) “(1)” or the like is added to the end of the file name, and the file name is changed and recorded.

  FIG. 5 is a flowchart showing a recording start operation in a conventional recorder that generates the file name as described above. In this operation, a message such as “Do you want to overwrite?” Is displayed to prompt the user to select. That is, when the operation is started, first, in step 51, the operation waits for the operation of the recording key instructing the recording start request. When the operation of the recording key is detected, the process proceeds to step 52, and the file name of the file for storing the recording data is generated based on the current date and time. This file name is generated as a name that can be distinguished in seconds as in the above example.

  Next, in step 53, it is determined whether or not a file having the same file name as the generated file name already exists. If it is determined that there is no file with the same file name, the process proceeds to step 54, a file with the generated file name is created, recording on the file is started, and the operation of FIG.

  If it is determined in step 53 that a file with the same file name exists, the process proceeds to step 55, where a message “Do you want to overwrite?” Is displayed and the user's instruction as to whether or not to overwrite is accepted. Next, it is determined whether or not the instruction from the user is an instruction to overwrite. If it is determined that the instruction is not for overwriting, the operation of FIG. If it is determined that the instruction is to overwrite, an existing file having the same file name as the generated file name is deleted in step 57, and the process proceeds to step 54. In this case, a file with that file name is newly created, and recording for the file is started.

  Since the file name is generated up to “seconds” when generating the file name using the recording date and time in step 52, the recording is stopped from the start of recording in step 54, and further in the next step 54 Normally, there is no possibility that the same file name is generated unless an operation for starting recording is performed within one second. In other words, the user's key operation is actually limited, and the processing capability (speed) of the recorder is limited, so the file names will not match unless the clock of the recorder is reset.

  As a technique for dealing with such conflicting file names, if the file name of an audio file to be recorded at a preset bit rate conflicts with the file name of an existing audio file, the existing file name There is also known one that displays the bit rate of an audio file and allows the user to select whether to overwrite and record, or to change the set bit rate (see Patent Document 1). ).

JP 2006-228086 A

  However, according to the above-described prior art, a file name that coincides with year, month, day, hour, minute, and second cannot be generated in normal use, but the same file name is used when the clock of the recorder is not set correctly. May be generated. In this case, the following problems occur when the operations (1) to (3) described above are performed.

  That is, when a message such as “Do you want to overwrite?” Is displayed as in (1) and the user is asked to make a selection, a troublesome and complicated selection operation is performed for the phenomenon that rarely occurs. It will be strong and is not preferable. Further, if the message is displayed as shown in (2) and overwriting is performed without asking for confirmation, an important file may be deleted. Further, when the file name is changed as in (3), the file name generation program becomes complicated and it is difficult to see when the file names are displayed in a list. It is not preferable to create a program with a complicated specification in order to deal with a condition that rarely occurs.

  An object of the present invention is to provide a more preferable process in the case where a file name of a file to be created already exists in a recording apparatus that creates and records a file at the start of recording in view of the problems of the conventional technology. There is to do.

  In order to achieve this object, a recording apparatus according to a first aspect of the present invention includes a time measuring means for outputting a current time, an instruction means for accepting an instruction to record predetermined data, and a recording of the data for a predetermined storage. A recording means for the means, a file name generating means for generating a file name using the current time by the time measuring means when receiving an instruction by the indicating means, and a file name generated by the file name generating means And the existing file name recorded by the recording means, and if there is a file name based on the same time, data recording by the recording means is prohibited, and there is no file name based on the same time In this case, the recording apparatus includes control means for recording data with the generated file name.

  Here, for example, a recording device or a digital camera corresponds to the recording device. As the file name using the current time, for example, the file name used up to the year, month, day and hour / minute / second of the current time is applicable. As the predetermined data, audio data in a recorder and image data in a digital camera are applicable. Examples of the instruction means include one that accepts a recording start instruction based on pressing of a recording start button in a recorder, and one that accepts an instruction to record captured image data based on pressing of a shutter button in a digital camera. To do. The predetermined storage means corresponds to, for example, a hard disk built in the device or a semiconductor memory mounted on the device. The range of existing file names that can be compared with the generated file names includes existing files on the entire recording medium, and existing files that exist only in folders and directories that are to be recorded on the recording medium. To do.

  In this configuration, when the control unit accepts an instruction to perform data recording by the instruction unit, the generation unit generates a file name using the current time. Then, the file name is compared with the existing file name, and if there is no file name based on the same time, data recording is performed with the generated file name. Data recording is prohibited when file names based on the same time exist. In this case, since data recording is not performed, when the recording instruction is issued again by the instruction unit by the user, the file name generated by the generation unit according to this is a file name based on the same time. If not, data is recorded with the generated file name.

  When generating a file name using “seconds” of the current time, the file name generated based on the current time at the time when the recording start instruction is issued is rarely caused by resetting the time measuring means, etc. There may be a file name based on the same time, but even in that case, the file name generated in response to the next recording start instruction does not have a file name based on the same time. The probability of being a thing is very high. Therefore, when recording is not performed when the user issues a recording start instruction, the user can perform recording only by performing the recording start instruction again. At this time, there is no request for input such as confirmation of whether or not overwriting is possible. In addition, the file name to be generated is not added with a character different from usual, but is generated using the current time as usual.

  In a recording apparatus according to a second invention, in the first invention, when the control unit prohibits the recording of data by the recording unit, the file name generation unit subsequently uses a file name different from the file name based on the same time. Is generated, the data is recorded with a file name different from the file name based on the same time.

  A recording apparatus according to a third invention is the recording apparatus according to the second invention, wherein, when the recording means prohibits the recording of data by the recording means, the file name generating means generates the file name again after a predetermined time elapses. It is characterized by being.

  A recording apparatus according to a fourth invention is characterized in that, in the first invention, when the recording means prohibits data recording, the control means performs an output prompting the instruction means to give another instruction. And

  According to a fifth aspect of the present invention, there is provided a recording apparatus comprising the recording apparatus according to any one of the first to fourth aspects, wherein an input audio signal is recorded by the recording apparatus.

  A program according to a sixth invention causes a computer to function as each means in the device according to any one of the first to fourth inventions.

  According to a seventh aspect of the present invention, there is provided a recording method comprising: a time measuring process for outputting a current time; an instruction process for receiving an instruction to record predetermined data; and recording the data to a predetermined storage means. A recording step to be performed; a file name generation step for generating a file name using the current time by the timing step when the instruction by the instruction step is accepted; a file name generated by the file name generation step; and the recording Contrast with the existing file name recorded by the process, if there is a file name based on the same time, the recording of data by the recording process is prohibited, and if the file name based on the same time does not exist, And a control step of recording data by the recording step using the generated file name.

  According to the present invention, a file name using the current time is generated based on a data recording instruction, and if the file name does not exist with the same time, the generated file name is used. Data recording is performed, and when the file name based on the same time exists, the data recording is prohibited. Therefore, when the user does not perform the data recording even though the data recording is instructed. Since no instruction is input, data recording can be performed simply by performing the data recording instruction again.

  In addition, it is not necessary to accept input such as confirmation of whether or not to overwrite, and to add a serial number etc. to a file name that has a file name based on the same time so that the file name does not have to be unique. Can be simplified. Further, it is assumed that all the file names are not the ones using serial numbers and the like using the current time, and special file names with serial numbers and the like can be excluded from the display of the file list.

  FIG. 1 is a block diagram showing a configuration of an audio recording apparatus according to an embodiment of the present invention. As shown in the figure, this apparatus requires a processing unit 11 for performing various processes such as control of each part of the apparatus and recording of audio, a storage unit 12 accessed by the processing unit 11, and a processing unit 11 for the user. A display unit 13 for displaying information, an operation unit 14 for performing an operation input instructed by the user to the processing unit 11, and an audio input unit for converting a voice to be recorded into an audio signal and supplying the audio signal to the processing unit 11 15 and an audio output unit 16 that outputs an audio signal from the processing unit 11.

  The storage unit 12 is configured using a drive device such as a hard disk, a flash memory, a magnetic tape drive, an MD, a CD, or a DVD. Audio data from the processing unit 11 is recorded in the storage unit 12 as a file in a predetermined format. As the file format, for example, MP3, WMA, WAV or the like can be used. The sound input unit 15 receives sound from a microphone or an external device.

  The processing unit 11 realizes a user interface function via the operation unit 14 and the display unit 13 according to a predetermined program, accepts a user instruction regarding the start and end of recording of audio data, and performs an operation according to the instruction. . The operation unit 14 includes a recording key for requesting start of recording and a stop key for requesting stop of recording. When recording audio, the audio signal from the audio input unit 15 is converted into data of a predetermined format by the processing unit 11 and recorded as a file of a predetermined format in the storage unit 12. The processing unit 11 has a timekeeping function, and uses time information obtained by timekeeping as a file name of a file used for recording.

  FIG. 2 is a flowchart showing the recording start process by the processing unit 11. When the process is started, first, in step 21, whether or not the recording key for requesting the start of recording is operated is monitored. When the operation of the recording key is detected, the process proceeds to step 22 where a file name for storing the recording data is generated based on the current time at that time. This file name is generated using up to “seconds” of the current time. For example, if the current time is January 23, 2008 12:34:56, a file name “2008013123456.MP3” is generated. “MP3” is an extension indicating that the file format is MP3.

  Next, in step 23, it is determined whether or not a file having the same file name as the generated file name exists in the storage unit 12. If it is determined that there is no file with the same file name, the process proceeds to step 24, a file with the generated file name is created, recording on the file is started, and the process of FIG.

  If it is determined in step 23 that the same file name exists, the process proceeds to step 25, and the process returns to step 21 without creating a file with the generated file name and without starting recording. In this case, since the recording is not started, if the user thinks that the operation of the recording key is incomplete and operates the recording key again within a few seconds, the file name is generated again in step 22. At this time, since one second or more has passed since the previous operation of the recording key, the file name generated again is different from the previous one. In addition, the recording key and stop key operations are repeated in a short time of several seconds, and it is impossible to create a plurality of files following the device. The probability of existing in the storage unit 12 is very low. Therefore, the process proceeds to step 24, and the probability that recording of a file name that is generated again is started is very high.

  According to the present embodiment, when the file name generated according to the operation of the recording key matches the file name of the existing file, the user does not generate the file and starts recording, and the user does not do anything about it. Since the user has accepted the operation of the recording key again without requesting confirmation of the recording key, the user thinks that the operation of the recording key has not been reliable when the recording key operation does not start, and simply restarts the recording key. Recording can be started simply by operating.

  That is, basically, the recording date and time are unlikely to match, and if they match, recording can be started by pressing the recording key again. Even when the recording key is pressed again, the possibility that the file names match is very low unless the user intends to do so. Since the condition rarely occurs, the user may think that the record key does not work, and operates the record key again without any doubt. That is, it is more kind to the user than to request a selection operation for whether to overwrite or not.

  On the other hand, the control program can be of a simple specification as much as the conventional process of requesting confirmation input of whether or not overwriting is possible and the process of changing the file name by adding serial numbers or the like. Therefore, it is possible to reduce the control program development man-hours and evaluation man-hours.

  FIG. 3 is a flowchart showing another example of the recording start process by the processing unit 11. The process of steps 31 to 34 in the figure is the same as the process of steps 21 to 24 in FIG. The processing of FIG. 3 differs from the processing of FIG. 2 in that if it is determined in step 33 that a file having the same file name as the generated file name exists in the storage unit 12, a message is displayed in step 35. However, the processing of FIG. 3 is terminated. In this case, since recording is not started, immediately in step 31, the operation of the recording key is waited.

  The message displayed in step 35 corresponds to a message such as “Recording cannot be started because the file name is duplicated. Please perform the recording start operation again”. If the user views the message and operates the recording key again, the operation is detected in step 31. At this time, since it is almost the case that 1 second or more has passed since the previous operation, a unique file name that does not exist in the storage unit 12 is generated (step 32), and recording is started (step 33). 34) The probability is very high.

  According to this, if the recording is not started when the user operates the recording key, the probability that the recording can be started without any trouble just by operating the recording key again in response to the message is very high. high.

  FIG. 4 is a flowchart showing still another example of the recording start process by the processing unit 11. In this process, the file name of the recording file is generated using the time when the recording key is operated, but if the generated file name is the same as the existing file name, the file name generation algorithm The file name is generated again after waiting for the elapse of a minimum unit time corresponding to 1 second, for example, 1 second. The re-generation is repeated up to a predetermined number of times until a unique file name is obtained.

  That is, when the process is started, the operation of the recording key is waited in step 41. When the operation of the recording key is detected, the retry counter C is cleared in step 42, and then the file name is generated based on the current time in the same manner as described above in step 43. Next, in step 44, it is determined whether or not the generated file name already exists. If it does not exist, a file with the generated file name is created and recording is started, and the process of FIG. 4 is ended.

  If it is determined in step 44 that the file name is the same as the existing file name, it is determined in step 46 whether the retry counter c has exceeded 9. If it is determined that the number exceeds 9, the process of FIG. If it is determined that the number does not exceed 9, the retry counter c is incremented in step 47, and after a predetermined time has elapsed in step 48, the process returns to step 43. In other words, if a unique file name cannot be obtained, file name generation is repeated with a predetermined time interval up to 10 times, and if a unique file name is still not obtained, the process is terminated. I have to.

  The predetermined time corresponds to, for example, 1 [second] when the file name is generated up to “second” of the current time in step 43. This is to change the generated file name without fail and increase the probability of obtaining a unique file name. However, even if the file name is regenerated after 1 second, the file name may not be unique. Therefore, here, the retry counter C limits the number of retries to 10 and repeats the generation of the file name. Yes.

  According to this, a file with a unique file name can be created and recording can be started without imposing any burden on the user.

  In addition, this invention is not limited to the above-mentioned embodiment, It can deform | transform and implement suitably. For example, in the above description, the area to be recorded is regarded as the storage unit 12, and in correspondence therewith, the presence or absence of the same file name as the file name generated in step 22 is checked for the file in the storage unit 12. However, when the storage unit 12 is managed in a hierarchical structure with folders and directories, the presence or absence of the same file name is checked in step 23 for the files in the folder or directory to be recorded. May be.

  In the above embodiment, an example in which the file name generated based on the current time is generated as “2008013123456.MP3” when the current time is January 23, 2008, 12:34:56, for example, will be described. did. In this case, if a file with the same name exists for some reason, recording with the same file name is prohibited. If the file name “2008013123457.MP3” is generated by the user's operation again, the existing “2008013123456.MP3” is generated. ", It is possible to record data.

  The file names to be compared here are not limited to those expressing the year, month, day, time by numbers as described above, but may be file names generated based on the serial value of the current time. For example, if the serial value of January 1, 1900 is “1”, the serial value of the time is “39470” on January 23, 2008. Similarly, the serial value of the time is “0:00:00”. If it is “0”, it becomes “0.52426” in the case of 12:34:56.

  The file name generated based on the serial value of the current time has an example such as “39470-52426.MP3”, and a file having the same file name as the file name thus generated already exists. If the file name is “39470-52427.MP3”, the data can be recorded when the file name generated based on the current time is “39470-52427.MP3”.

It is a flowchart which shows the recording start process by the process part of the apparatus of FIG. It is a flowchart which shows another recording start process by the process part of the apparatus of FIG. 6 is a flowchart showing still another recording start process by the processing unit of the apparatus of FIG. 1.
