Description

  The present invention relates to a backup control apparatus, and in particular, is suitably used for automatically backing up an image file taken by a digital camera to an external storage device connected to the digital camera in accordance with an operator's intention. The present invention relates to a backup control device that can be used.

  Conventionally, an external storage device having a liquid crystal display may be connected to a digital camera such as a digital still camera or a digital video camera.

  When a conventional external storage device is connected to a digital camera, the image file generated by the digital camera is generally backed up manually or automatically. In general, JPEG files and RAW files are often used as image file types. Then, the digital camera generates one image file of the JPEG file or the RAW file, or both the JPEG file and the RAW file based on one image data obtained by shooting.

  However, since the conventional external storage device does not have a device for controlling the backup of the image file in accordance with the intention of the operator of the external storage device, the digital camera creates both the JPEG file and the RAW file. In that case, there was a problem that both of the image files had to be backed up.

  Therefore, since the file size of the RAW file is larger than the file size of the JPEG file, the transfer speed of the RAW file from the digital camera to the external storage device is slower than the transfer speed of the JPEG file in inverse proportion thereto. As a result, the transfer rate from the digital camera to the external storage device is reduced.

  Further, since the image file is also stored in the storage device built in the digital camera, the operator of the external storage device has not necessarily requested to capture all the image files generated by the digital camera. On the other hand, since the RAW file is an unprocessed image file, it is highly important as an image file. Therefore, there is a demand that the operator wants to back up at least the RAW file as a precaution. Was.

  There has also been a desire to limit the image files to be backed up in order to extend the drive time of a digital camera or a conventional external storage device.

  In addition, when continuous shooting is performed with a digital camera, if the transfer from the digital camera to the external storage device is not in time, the remaining capacity of the storage device of the digital camera is lost, causing continuous shooting to stop.

  Therefore, the present invention has been made in view of these points, and an image is transferred from a digital camera to an external storage device in accordance with an operator's intention represented by improvement in transfer speed and reliable backup of important image files.

  Hereinafter, a backup control apparatus according to the present invention will be described with reference to an embodiment thereof.

  As shown in FIGS. 1 and 2, the backup control device 1 according to the present embodiment is normally built in an external storage device 12 connected to the digital camera 10 via, for example, a USB cable 11. The backup control device 1 is mainly composed of a processing device (for example, CPU) 2, a main storage device (for example, memory (RAM)) 3a, and an auxiliary storage device (for example, storage (HDD)) 3b. A device connection device (for example, USB connection device) 4 and a touch panel type display (for example, LCD) 5 composed of a display device 5 a and an input device 5 b are provided as a shared component of the external storage device 12 or a dedicated component of the backup control device 1. Yes. The backup control device 1 is preferably composed of an input device 5b and a processing device 2 as arbitrary devices, and preferably has a release device for instructing photographing with the digital camera 10.

  Examples of the input device 5b include a position input device that allows an operator to input an operation desired by pressing a screen display displayed on the display device 5a of the display 5. This input device 5b is used to select a backup desired file and a backup format.

  Here, the backup desired file is one or more image files desired to be backed up from two or more image files generated from one image data obtained by photographing with the digital camera 10.

  Here, first, an image file generated by the digital camera 10 will be described. For example, when the digital camera 10 takes an image once, one image data (analog data) is obtained from an image sensor such as a CCD or CMOS built in the digital camera 10. The one image data is subjected to at least one of various processes such as A / D conversion, interpolation, color space conversion, and gamma characteristic conversion by an image processor (image engine) built in the digital camera 10. Thus, an image file (digital data) such as a RAW file and a JPEG file is generated from the one image data. The digital camera 10 of the present embodiment is set to generate two or more image files by one shooting.

  The two or more image files are image files that are distinguished into two or more based on the difference in file format, the size of the file capacity, the difference in transfer speed, and other desired file classifications. For example, in the case of distinction due to the difference in file format, the image file is distinguished according to the file format such as RAW or JPEG. Also, for example, in the case of distinction based on the difference in file capacity or the transfer speed, two or more image files obtained from one image data may have different file capacities or transfer speeds regardless of the file format. A distinction is made by comparing two or more image files. Of course, it is also possible to distinguish two or more image files from multiple viewpoints, such as distinguishing two or more image files from two viewpoints of difference in file format and size of file capacity.

  In general, when two or more image files are distinguished by a difference in file format, the management of the image files is easy. For this reason, two or more image files of the present embodiment are formed, for example, one RAW file and one JPEG file, one image file of the same file format, and a total of two or more image files are formed. It is preferable that the digital camera 10 is set so that the two or more image files are distinguished based on the difference in file format.

  The backup format selected by the input device 5b is divided into a first backup format and a second backup format. The first backup format is a backup format in which only backup desired files are backed up. The second backup format is a backup format in which a backup desired file is preferentially backed up over other image files. For example, when the first display screen A as shown in FIG. 3 is displayed on the display device 5a of the display 5 of the backup control device 1 shown in FIG. 2, the backup target file is “RAW file only”, “ “JPEG file only” or “all files” is selected.

  When “RAW file only” and “JPEG file only” are selected from the first display screen A, the input device 5b indicates that the backup format is the first backup format and the backup desired file is a RAW file or a JPEG file. It will be set from. In the first backup format, image files other than the backup desired file are not backed up.

  On the other hand, when “all files” is selected from the first display screen A, it is set from the input device 5b that the backup format is the second backup format. Then, as shown in FIG. 3, when switching from the first display screen A to the second display screen B by selecting “all files”, the backup priority file is selected from “RAW file” or “JPEG file”. The By this selection, the backup desired file becomes a RAW file or a JPEG file. In the second backup format, only the priority order of backup is determined, so that unlike the first backup format, not only the image file selected as the backup desired file but also other image files are backed up. Sometimes.

  The processing device 2 shown in FIG. 2 implements the functions described below by executing a predetermined program using the storage devices 3a, for example. The processing device 2 performs, for example, reception of a generation signal, transmission of a request signal, backup, and other various processes. The generation signal is a signal for the digital camera 10 to notify the backup control device 1 that the image file has been generated by photographing with the digital camera 10. The generation signal is classified into two or more types of a signal for notifying generation of a backup desired file and a signal for notifying generation of another image file in a certain file format.

  The request signal is a signal that requests the backup camera 1 to transfer the image file to be backed up to the digital camera 10 when the generation signal of the backup desired file is received from the digital camera 10. When the first backup format is selected by the input device 5b, a request signal for requesting transfer of only one image file to be a backup desired file is transmitted. On the other hand, when the second backup format is selected by the input device 5b, a request signal for requesting transfer of two or more image files including the backup desired file is transmitted.

  In the processing related to backup, one or more image files transferred from the digital camera 10 in response to the request signal are stored in the storage device 3 as backup files.

  The auxiliary storage device 3b stores the selected data and backup file selected by the input device 5b.

  Next, a control flow in the backup control device 1 will be described with reference to FIG. The control flow is mainly divided into three stages: the pre-backup stage (from S1 to immediately before S4), the backup stage for the desired backup file (from S4 to immediately before S9), and the backup stage for other image files (from S9 to immediately before SF). It is divided into.

  When the power source of the backup control device 1 is turned on, control by the backup control device 1 is started (SS), and the pre-backup stage (from S1 to immediately before S4) starts. When the operator of the backup control device 1 sets the backup desired file and the backup format (hereinafter referred to as “backup format etc.”) illustrated in FIG. 3 from the input device 5b (S1), the processing device 2 is arbitrarily set. As a function of determining whether or not the remaining power amount of each battery for driving the digital camera 10 or the input device 5b, the processing device 2 and the storage device 3 is greater than or equal to a predetermined amount (S2), and the digital camera 10 or the auxiliary storage device It is determined whether the remaining capacity of 3b is equal to or greater than a predetermined value (S3).

  If there is a predetermined value or more in both S2 and S3, the process proceeds to the next process (S4) according to the desired backup format in S1.

  On the other hand, when either one of S2 and S3 is less than or equal to the predetermined value, it is checked whether the backup format selected by the input device 5b is a power saving / small capacity type backup format or the like (S5). The power saving / small capacity type backup format is, for example, an image file with the smallest file capacity (for example, if the image file of 2 is a RAW file and a JPEG file, the JPEG file is the smallest image file). This corresponds to the first backup format used as a backup desired file.

  If it is determined in S5 that the power saving / small capacity type backup format or the like has been selected in S1, the process proceeds to S4, and in S1, the power saving / small capacity to the extent that backup can be performed with the remaining power amount or remaining capacity. When it is determined in S5 that the type backup format or the like is not selected, the setting is automatically changed to the power saving / small capacity type backup format or the like for the backup control device 1. However, automatic setting is not essential, and instead, a warning message or the like prompting the operator to change the setting may be output from the display device 5a of the display 5 as the second output signal. Thereby, the setting is manually changed to the power saving / small capacity type backup format for the backup control device 1. That is, in S6, the setting is changed so that shooting can be continued for as long as possible when the remaining battery level is low and when the auxiliary storage device 3b is low. By changing these settings, the process proceeds from S6 to S4.

  Next, it is a backup stage (from S4 to immediately before S9) of the backup desired file. For example, assuming that a backup desired file is an image file whose transfer speed is likely to be relatively fast due to a small capacity of a JPEG file or the like, it is easy to understand.

  When the digital camera 10 transmits various generation signals to the backup control device 1, the processing device 2 of the backup control device 1 receives these various generation signals. Then, it is determined from the generated signals received here whether the generated signal is related to the backup desired file (S4). When the processing device 2 receives the generation signal of the backup desired file, the processing device 2 transmits a request signal related to the backup desired file to the digital camera 10 and thereby the backup desired file transferred from the digital camera 10. Is backed up (S7).

  When the backup of the backup desired file is completed, it is checked whether or not a generation signal for the backup desired file is newly transmitted within a predetermined time (S8). If there is a new transmission (S8), the backup desired file is backed up (S7). If the time during which a generation signal of a new backup desired file is not received exceeds a predetermined time, the process proceeds to the next process (S9). If the generation signal for the backup desired file cannot be received in S4, the process similarly proceeds to the next process (S9).

  Here, with reference to FIG. 5, transmission / reception of signals between the digital camera 10 and the backup control device 1 in the backup stage (from S4 to immediately before S9) will be described.

  When shooting is performed with the digital camera 10 and a RAW file (id = 01) and a JPEG file (id = 02) are generated, a RAW file (id = 01) is created from the digital camera 10 to the backup control device 1. A completion notification (S21) and a JPEG file (id = 0) creation completion notification (S22) are sequentially performed.

  At this time, if the desired backup file is a JPEG file, the backup control device 1 ignores the RAW file (id = 01) creation completion notification and sends a data transfer request for the JPEG file (id = 02) to the digital camera. 10 is notified (S23).

  The digital camera 10 transfers the data of the JPEG file (id = 02) (S24).

  Returning to FIG. 4 again, finally, it is a backup stage of other image files (from S9 to immediately before SF). For example, the transfer speed tends to be relatively slow due to the large capacity of a RAW file or the like, but it is easy to understand when assuming that an image file having a high degree of importance is used for image processing as another image file.

  The processing device 2 of the backup control device 1 receives the generation signal of another image file from the digital camera 10 to the backup control device 1, but checks whether there is an image file that has not been backed up in the storage device 3. (S9). For example, in the example of FIG. 5, the RAW file (id = 01) is an image file that has received the generation signal but has not been backed up in the storage device 3.

  When there is another image file that has not been backed up, it is checked whether or not the other image file is desired to be backed up from the selection of the backup format (S10), and the backup is performed based on the second backup format. If so, backup of another image file is started when a predetermined start condition is satisfied (S11).

  The predetermined start condition is that the processing device 2 receives an input signal of either a manual signal or an automatic signal. The manual signal is a signal generated by manual operation obtained from the input device 5b. For example, a confirmation screen such as “Do you want to back up other image files?” Is displayed on the display device 5 a of the display 5, and accordingly, an input to backup is made from the input device 5 b of the display 5. This is the signal that is received. The automatic signal is a signal that is automatically generated when a predetermined time elapses from the end of the backup of the desired backup file. The predetermined time may be 0 seconds, may be a time desired by the operator, or may be a suitable time determined by the manufacturer of the backup control device 1.

  After the backup of another image file is started in S11, when the processing device 2 receives a generation signal of a newly generated backup desired file (S12), the backup desired file related to the new generation signal (subsequent generation signal) Is prioritized over the backup of the other image file being backed up according to the previous generation signal, the backup of the other image file according to the previous generation signal is interrupted (S13), and the backup of the new generation signal The backup desired file is backed up (S7). Since the other image file whose backup has been interrupted is recognized as another image file that has not been backed up in S9, the other image related to the previous generation signal after the backup of the backup desired file related to the new generation signal is completed. File backup resumes (S10, S11).

On the other hand, when the processing device 2 does not receive another new generation signal from the start to the end of the backup of another image file in S11 (S12), the backup of the other image file is ended (S14). It is confirmed again whether there is another image file that has not been backed up (S9).
When it is determined in S9 that there is no other image file that has not been backed up, the control by the backup control device 1 ends (SF).

  When backup of the desired backup file or other image file is completed, the same image file is stored in the digital camera 10 and the storage device 3 of the backup control device 1 one by one. For example, when the digital camera 10 generates a JPEG file having a high transfer speed and a small capacity and a RAW file having high storage importance, the JPEG file may be deleted as soon as the shooting can be confirmed. There is also a demand for storing in a storage device 3 other than 10 for a long time.

  Therefore, the processing device 2 uses the image file with the smallest file capacity (for example, a JPEG file) as a backup desired file, and based on the second backup format, two or more image files (for example, two image files of a JPEG file and a RAW file). It is preferable to back up. Thereafter, one or more images obtained by removing the highest quality image file (for example, RAW file) from two or more image files (for example, two image files of JPEG file and RAW file) generated from the same image data. It is preferable to delete part or all of a file (for example, a JPEG file) (for example, some unnecessary JPEG files among a plurality of JPEG files) from the storage device 3. This may be automatically deleted by the processing device 2 or may be manually deleted by the operator's operation from the input device 5b.

  At the same time, among the two or more image files stored in the digital camera 10 (for example, two image files of a JPEG file and a RAW file), the backed up image file (for example, a JPEG file or a RAW file) is completed. It is preferable to delete part or all of one or two or more image files that are the same as one or both of them. Therefore, it is preferable that the processing device 2 transmits an erasure signal for requesting or executing the erasure to the digital camera 10 after the backup of each image file is completed.

  Next, the operation of the backup control device 1 of this embodiment will be described.

  In the backup control device 1 of the present embodiment, as shown in FIG. 4, when the operator of the backup control device 1 selects a backup desired file (one or more image files) and a backup format by the input device 5b, As shown in FIG. 3, the processing device 2 performs processing so that only the backup desired file or the backup desired file is backed up (S4, S7, etc.). Therefore, it is possible to automatically back up one or more image files desired to be backed up from two or more image files generated by the digital camera 10 according to the image file.

  In the backup control device 1 of the present embodiment, it is preferable that two or more image files are distinguished based on differences in file formats. Thereby, it becomes the same as the classification of general image files such as the classification in the digital camera 10, and it becomes easy to automatically back up according to the intention of the operator.

  In addition, it is preferable that the processing apparatus 2 of the present embodiment transmits an erasure signal for requesting or executing erasure of a part or all of the image file that has been backed up to the digital camera 10. As a result, the remaining capacity of the digital camera 10 can be increased after the image file is backed up.

  Further, the processing apparatus 2 of the present embodiment uses two or more images generated from the same image data after backing up two or more image files based on the second backup format using the image file with the smallest file capacity as a backup desired file. A part or all of one or two or more image files obtained by removing the image file of the highest quality from the image file of the above are automatically deleted from the storage device 3, or the image file to be deleted is deleted from the storage device 3. It is preferable to output a first output signal that prompts the operator to input.

  Since the backup desired file is sequentially stored in the storage device 3 of the backup control device 1, if the image file having the smallest file capacity is the backup desired file, early shooting confirmation in the backup control device 1 becomes possible. In addition, by deleting one or more image files excluding the image file with the highest image quality from the storage device 3 after all the backups are completed, the image file with the smallest file size that has been backed up early for the purpose of early shooting confirmation Therefore, the remaining capacity in the storage device 3 can be effectively used while backing up important image files.

  In addition, when performing the backup based on the second backup format, the processing device 2 of the present embodiment preferably starts backup of another image file when a predetermined start condition is satisfied. By controlling the backup start timing of other image files, the transfer speed between the digital camera 10 and the backup control device 1 can be controlled, so that the comfort of image file transfer and backup can be improved. it can.

  In addition, the predetermined start condition of the present embodiment is a manual signal generated by a manual operation obtained from the input device 5b or an automatic signal generated automatically after a lapse of a predetermined time from the end of backup of the backup desired file. It is preferable that the processing apparatus 2 receives any one of the input signals. In this case, since the backup time of the desired backup file does not overlap with the backup time of other image files, it is possible to flexibly improve the comfort of image file transfer according to each image file.

  In addition, when the processing apparatus 2 according to the present embodiment receives a generation signal newly transmitted from the digital camera 10 when performing backup based on the second backup format, the processing apparatus 2 is backed up based on the generation signal ahead. It is preferable to interrupt backup of other image files other than the desired backup file, and to preferentially back up the desired backup file based on the new generation signal. As a result, the start of the backup of the newly created backup desired file created by the backup of the other previously created image file is not delayed, so that the newly created image file can be confirmed at an early stage. In addition, the backup of the other image file created earlier can be resumed after the backup of the newly created backup desired file is completed.

  Further, the processing device 2 of the present embodiment is configured so that the remaining power amount of each battery for driving the digital camera 10 or the input device 5b, the processing device 2, and the storage device 3 becomes equal to or less than a predetermined value, or When either one of the remaining capacity of the image file becomes less than the predetermined value is satisfied, the image file with the smallest file capacity is automatically changed as a backup desired file, or the operator is prompted to change the setting. It is preferable that only the desired backup file is backed up based on the first backup format. Thereby, even if the remaining power amount of each battery decreases or the remaining capacity of the digital camera 10 or the storage device 3 decreases, the capacity of the battery or the storage device 3 can be used as long as possible. Image files can be backed up.

  That is, according to the backup control device 1 of the present embodiment, as shown in the above operation, the backup is controlled according to the type and transfer state of the image file, the remaining amount of battery power, the remaining capacity of the storage device 3 and the like. As a result, the image file can be automatically backed up from the digital camera 10 to the external storage device 12 in accordance with the operator's intention such as improvement of transfer speed and reliable backup of important image files.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.
