Description

  The present invention relates to a data recording apparatus and a data restoration guiding method in the data recording apparatus. Specifically, the present invention relates to a user for allowing a user to select whether or not to perform data restoration when the recording medium is removed from the recording medium mounting section and data recording is interrupted while data is being recorded. The present invention relates to a data recording apparatus or the like that reduces the possibility that a user will leave a recording medium in an abnormal state by displaying an interface screen.

  2. Description of the Related Art Conventionally, camcorders (video camera recorders) that use a recording medium such as a video tape, a DVD (Digital Versatile Disc), and a hard disk drive in a detachable manner have been widely used. In such a camcorder, when the recording medium is taken out during the recording process, the image data recorded on the recording medium is damaged, and the image data cannot be read normally, and the recording medium itself is damaged. The recording medium itself may be unusable. Therefore, such a camcorder is generally locked so that the recording medium is not taken out during the recording process.

  In recent years, a camcorder that uses a memory card such as a memory stick (registered trademark of Sony Corporation) as a recording medium has been proposed (see, for example, Patent Document 1). Memory cards are mainly used in advance of electronic devices such as mobile phones and digital still cameras. Many of these electronic devices do not employ the above-described lock function, and the memory cards can be inserted and removed at any time. That is the general perception of the user.

  Therefore, if a lock mechanism is provided in the memory card storage section of the camcorder, the user will feel uncomfortable, the configuration of the memory card storage section will be complicated, and the cost will be increased. However, if the camcorder is not provided with a lock mechanism, there is a risk that the memory card is removed by the user during the recording process. When the memory card is removed during the recording process, data being recorded is lost, and in the worst case, the entire recording area of the memory card becomes unusable.

Therefore, conventionally, as a countermeasure against recording abnormalities caused by the removal of the memory card that is being recorded, a cover is provided on the memory card mounting portion of the camcorder, and when the cover is opened, and as a result of removing the memory card, When it was detected that the recording could not be completed, a warning was displayed in two stages. Also, when a memory card that has been removed next time is inserted, an inquiry is made as to whether or not to perform data restoration processing. In this case, when a memory card different from the removed memory card is inserted, data used for restoration is discarded and normal recording is performed on a new memory card.
JP 2005-175844 A

  As described above, a camcorder that is configured to display a two-stage warning has the following problems, for example.

(1) It is easy to forget that there is a recording error in the memory card that the user has removed.
(2) Although there is a high possibility that an abnormal operation will occur when the removed memory card is used in another device, it is difficult to detect this abnormal state in another device. For this reason, as a result of continuing to operate the recording medium in an abnormal state, information recorded after the occurrence of the abnormality may be damaged.

  (3) If a memory card different from the removed memory card is installed by mistake, it cannot be restored. In particular, if the memory card is small and an individual identification label cannot be attached, the memory card to be repaired is likely to be mistaken.

  An object of the present invention is to reduce the possibility of a user leaving a recording medium in an abnormal state.

The concept of this invention is
A recording medium mounting section for detachably mounting the recording medium;
A data recording unit for recording data on a recording medium mounted on the recording medium mounting unit;
When data is being recorded on the recording medium by the data recording unit, when the recording medium is removed from the recording medium mounting unit and data recording is interrupted, the user selects whether to perform data restoration. And a display control unit that displays a first user interface screen.

  In the present invention, a recording medium mounting portion for detachably mounting the recording medium is provided. The recording medium is not limited to the memory card, and any recording medium may be used. Data is recorded by the data recording unit on the recording medium mounted on the recording medium mounting unit. The data is image data, audio data, text data, or the like. For example, an imaging unit that images a subject is provided, and image data obtained by imaging with the imaging unit is recorded.

  Whether data is restored by the display control unit when data is being recorded on the recording medium by the data recording unit, that is, during the recording process, when the recording medium is removed from the recording medium mounting unit and data recording is interrupted A first user interface screen for allowing the user to select whether or not is displayed.

  Thus, by displaying the first user interface screen, the user who has removed the recording medium can easily recognize the necessity of data restoration for the removed recording medium, and selects to perform data restoration. It is expected that. Therefore, it is possible to reduce the possibility that the user will leave the recording medium in an abnormal state.

  In the present invention, for example, when the data restoration is selected based on the first user interface screen, the display control unit guides the recording medium removed from the recording medium mounting unit to be mounted again. A second user interface screen may be displayed.

  For example, when a recording medium is not attached to the recording medium attachment unit, a user interface screen that prompts the user to attach a recording medium removed from the recording medium attachment unit is displayed as the second user interface screen. In addition, for example, when the recording medium attached to the recording medium attachment unit determines that the recording medium attached to the recording medium attachment unit is not the same as the recording medium removed from the recording medium attachment unit, the data restoration is performed as the second user interface screen. A user interface screen indicating that the recording medium is different from the target is displayed.

  In this way, by displaying the second user interface screen, the user can easily and reliably remount the recording medium removed during the recording process, and can promptly perform data restoration on the recording medium. it can.

  In the present invention, for example, when the first user interface screen is displayed by the display control unit, another operation is performed until it is selected whether or not to perform data restoration based on the first user interface screen. It may be made to further be provided with a mode control part which controls not to shift to a mode. By performing mode control in this way, the probability that the user who removed the recording medium will immediately select data restoration is increased, and the possibility that the user will leave the recording medium in an abnormal state can be reduced.

  In the present invention, for example, when the data recording unit selects not to perform data restoration based on the first user interface screen, the data remaining without being recorded because the data recording is interrupted. May be discarded. As a result, the data recording unit can perform normal recording on the recording medium to be mounted next in the recording medium mounting unit, and can record without waiting for the time required for data restoration.

  In the present invention, for example, when the display control unit is selected not to perform the data restoration based on the first user interface screen, the third user interface for allowing the user to confirm the cancellation of the data restoration. The screen further displays the data recording unit, when the cancellation of the data restoration is confirmed based on the third user interface screen, discards the data that remains without being recorded because the data recording is interrupted, It may be made like. In this way, by asking for user confirmation, it is possible to cope with a case where the user erroneously selects not to perform data restoration.

  According to the present invention, when the recording medium is removed from the recording medium mounting portion and the data recording is interrupted while the data is being recorded, the user interface for allowing the user to select whether or not to perform the data restoration. The screen is displayed and the possibility that the user will leave the recording medium in an abnormal state can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an external configuration example of a camcorder 100 as an embodiment. The camcorder 100 mainly includes a main body 120 having an imaging lens 111 and the like, and an LCD (Liquid Crystal Display) panel 118. The LCD panel 118 is connected to the main body 120 by a rotation connecting part 122 so as to be rotatable in two directions, a horizontal direction and a vertical direction. The user can adjust and use the display surface of the LCD panel 118 so as to face a desired direction.

  A user operation unit 102 on which operation buttons and the like for the user to perform various operations is formed on the housing surface of the main body 120 and the LCD panel 118. A touch panel (not shown in FIG. 1) is disposed on the screen of the LCD panel 118. The user can perform various operations by designating a position on the screen by directly touching the touch panel with a finger or touching with a pen.

  The main body 120 is provided with a card mounting portion 123. A memory card 115 as a recording medium, for example, a memory stick (MS), is detachably mounted on the card mounting unit 123. The illustrated state shows a state in which the memory card 115 is attached to the card attachment unit 123. In the camcorder 100, at the time of imaging / recording, an imaging process is performed by an imaging device (not shown in FIG. 1) based on the imaging light captured by the imaging lens 111 to obtain an imaging signal. Then, an image (captured image) based on the imaging signal obtained by the imaging element is displayed on the LCD panel 118, and the user can visually recognize the captured image. Further, the image data obtained by the image sensor is recorded on the memory card 115 attached to the card attachment unit 123.

  FIG. 2 shows a circuit configuration example of the camcorder 100. The camcorder 100 includes a control unit 101, a user operation unit 102, a power supply circuit 103, a battery 104, an AC power plug 105, a power switch 106, an imaging lens 111, an imaging element 112, and an imaging signal processing circuit. 113, a recording unit 114, a memory card 115, an OSD circuit (on-screen display circuit) 116, a superimposing circuit 117, an LCD panel 118, and a touch panel 119.

  The control unit 101 controls the operation of each unit of the camcorder 100. The user operation unit 102 is connected to the control unit 101. As described above, the user operation unit 152 is an operation button or the like disposed on the main body 120 of the camcorder 100 and the casing surface of the LCD panel 118. The control unit 101 is supplied with power from an AC power plug 105 connected to a battery 104 or a commercial power source via a power circuit 103. When an operation input signal for turning on the power is supplied in response to an operation input to the user operation unit 102 by the user, the control unit 101 switches the power switch 106 to a connected state and supplies power to each unit. And a standby mode for waiting for a recording start instruction from the user is entered.

  The image sensor 112 is configured by, for example, a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or the like. The imaging element 112 performs an imaging process in a state where an optical image of a subject is formed on the imaging surface by the imaging lens 111, and outputs an imaging signal. The image signal processing circuit 113 performs sample hold and gain control, conversion from an analog signal to a digital signal, white balance adjustment, gamma correction, and the like for the image signal (analog signal) output from the image sensor 112. Captured image data is generated.

  The recording unit 114 includes a card mounting unit 123 for detachably mounting the memory card 115. The recording unit 114 performs an encoding process by the MPEG (Moving Picture Experts Group) method on the captured image data obtained by the imaging signal processing circuit 113 after shifting from the standby mode to the recording mode in accordance with a recording start instruction from the user. In this way, recording data that has been compression-encoded is generated, and this recording data is recorded on the memory card 115. In this case, a recording format for recording the recording data as a file on the file system is adopted. When recording data is recorded in the memory card 115, the recording unit 114 records the recording data and information incidental to the recording process in the temporary storage unit 114a configured by, for example, a flash memory, and each time a predetermined amount is accumulated. The recording data is transferred from the temporary storage unit 114a to the memory card 115 and recorded.

  The OSD circuit 116 sends a screen information display signal created on the VRAM 116 a to the superimposing circuit 117 in scan units in accordance with the screen information display request issued by the control unit 101. The control unit 101 issues a screen information display request to the OSD circuit 116 in order to display screen information including a warning display. In this sense, the control unit 101 constitutes a display control unit. The superimposing circuit 117 superimposes the screen information display signal from the OSD circuit 116 on the captured image data obtained by the imaging signal processing circuit 113 and outputs it to the LCD panel 118.

  As described above, the LCD panel 118 is composed of, for example, an LCD, a PDP, or the like. The touch panel 119 constitutes a position designation unit that designates a position on the screen of the LCD panel 118 and is arranged on the screen of the LCD panel 118. The touch panel 119 is connected to the control unit 101. The user can perform various operations on the screen of the LCD panel 118 by directly touching a predetermined position on the touch panel 119 with a finger or a pen corresponding to the display of the screen information on the LCD panel 118. .

  Next, the operation of the camcorder 100 shown in FIG. 2 will be briefly described.

  When the user performs a power-on operation using the user operation unit 102, the control unit 101 controls the power switch 106 to be connected to supply power to each unit, and enters a standby mode in which the user waits for a recording start instruction. . In this standby mode, the following operation is performed.

  In other words, the imaging signal obtained by performing the imaging process with the imaging element 112 is supplied to the imaging signal processing circuit 113. In this image signal processing circuit 113, the image signal from the image sensor 112 is subjected to sample hold and gain control, conversion from an analog signal to a digital signal, white balance adjustment, gamma correction, etc. Generated.

  Further, in accordance with the screen information display request issued by the control unit 101, a screen information display signal created on the VRAM 116a of the OSD circuit 116 is sent to the superimposing circuit 117 in units of scanning. In the superimposing circuit 117, the screen information display signal from the OSD circuit 116 is superimposed on the captured image data obtained by the imaging signal processing circuit 113. The captured image data on which the screen information display signal output from the superimposing circuit 117 is superimposed is supplied to the LCD panel 118. As a result, a captured image is displayed on the LCD panel 118, and screen information as a user interface screen is displayed on the captured image.

  In the above-described standby mode, when the user gives a recording start instruction using the user operation unit 102 or the touch panel 119, the recording mode is set. In this recording mode, in addition to the operation in the standby mode described above, the following operation is further performed. That is, in the recording unit 114, the captured image data obtained by the imaging signal processing circuit 113 is encoded by the MPEG method to generate recording data that is compression-encoded, and the recorded data is stored in the temporary storage unit 114a. Is recorded in the memory card 115 via

  Next, the control unit when recording data is being recorded on the memory card 115 by the recording unit 114, that is, when recording of the recording data is interrupted by removing the memory card 115 from the card mounting unit 123 during the recording process. A screen display control example 101 will be described.

  When the memory card (MS: Memory Stick) 115 is removed during the recording process, the display state shown in FIG. 3B is changed from the display state of the captured image shown in FIG. That is, in the display state shown in FIG. 3B, a user interface screen for allowing the user to select whether or not to perform data restoration is displayed.

  When the portion corresponding to the display location “Yes” on the touch panel 119 is pressed and data restoration is selected, as shown in FIGS. 3C, 4A, and 5A. Then, a user interface screen for prompting the re-installation of the memory card 115 removed (removed) from the card mounting unit 123 is displayed.

  When the memory card 115 is mounted (inserted) in the card mounting unit 123, when it is determined that the memory card 115 is not the same as the removed memory card 115, the display state as shown in FIG. Become. That is, in the display state shown in FIG. 4B, a user interface screen indicating that the memory card is different from the data restoration target (MS: Memory Stick) is displayed. Here, the determination of the identity of the memory card 115 can be performed using the ID when the ID is used as the individual identification information. The control unit 101 constitutes an identity determination unit.

  Further, when the memory card 115 is inserted (inserted) in the card mounting portion 123, when it is determined that the memory card 115 is the same as the removed memory card 115, as shown in FIG. Display state. Then, when a portion corresponding to the display location of “OK” on the touch panel 119 is pressed, a display state as shown in FIG.

  That is, in the display state shown in FIG. 5C, a user interface screen for allowing the user to select whether or not to execute data restoration is displayed. Then, when a portion corresponding to the display location “Yes” on the touch panel 119 is pressed and data restoration is selected, a display state as shown in FIG. 5D is obtained, and data restoration is performed. In this case, in the previous recording, the recording is interrupted and the recording data remaining in the temporary storage unit 114a is transferred to the memory card 115 and recorded, whereby the data is restored.

  In addition, when the memory card 115 is removed during the recording process, the display state of the captured image as shown in FIG. 6A is the same as shown in FIGS. 3A and 3B. Then, the display state as shown in FIG. 6B is displayed, and a user interface screen for allowing the user to select whether or not to perform data restoration is displayed.

  Based on this user interface screen, for example, when the portion corresponding to the display location of “No” on the touch panel 119 is pressed and it is selected not to perform data restoration, as shown in FIG. A user interface screen is displayed to allow the user to confirm the cancellation. In this case, when the portion corresponding to the “Yes” display location on the touch panel 119 is pressed and it is selected to cancel the data restoration, the data restoration is stopped and the restoration information is discarded. In this case, in the previous recording, the recording is interrupted and the recording data and the like remaining in the temporary storage unit 114a are discarded.

  FIG. 7 collectively shows examples of screen display control by the control unit 101 described above. That is, when the memory card (MS: Memory Stick) 115 is removed during the recording process from the display state of the captured image as shown in FIG. 7A, data restoration is performed as shown in FIG. 7B. A user interface screen for allowing the user to select whether or not is displayed. Based on this user interface screen, the user does not enter another operation mode until it is selected whether or not to perform data restoration.

  When the portion corresponding to the “Yes” display location on the touch panel 119 is pressed and data restoration is selected, as shown in FIG. 7C, the touch panel 119 is removed from the card mounting portion 123 (removed). ) The display state prompts the user to reinsert the memory card 115.

  When the memory card 115 is inserted (inserted) into the card mounting portion 123 and the portion corresponding to the “OK” display location on the touch panel 119 is pressed, the memory card 115 is not the same as the removed memory card 115. As shown in FIG. 7D, a user interface screen indicating that the memory card (MS: Memory Stick) is different from the data restoration target is displayed. In this case, when the memory card 115 attached to the card attachment unit 123 is removed, the memory card 115 removed (removed) from the card attachment unit 123 is reattached as shown in FIG. Is displayed.

  In the display state shown in FIG. 7C, when the memory card 115 is mounted (inserted) in the card mounting portion 123 and the portion corresponding to the “OK” display location on the touch panel 119 is pressed, the memory card 115 is pressed. Is the same as the removed memory card 115, a user interface screen for allowing the user to select whether or not to execute data restoration is displayed as shown in FIG. 7 (e).

  In this display state, when the portion corresponding to the “Yes” display location on the touch panel 119 is pressed and execution of data restoration is selected, data restoration is performed. On the other hand, in this display state, when the portion corresponding to the “No” display location on the touch panel 119 is pressed and it is selected not to execute data restoration, the card is again mounted as shown in FIG. The display state prompts the user to remount the memory card 115 removed (removed) from the unit 123.

  Further, as shown in FIG. 7B, a portion corresponding to the display location of “No” on the touch panel 119 in a state where a user interface screen for allowing the user to select whether or not to perform data restoration is displayed. When is pressed and it is selected not to perform data restoration, a user interface screen is displayed to allow the user to confirm the cancellation of data restoration, as shown in FIG.

  In this display state, when the portion corresponding to the display location of “Yes” on the touch panel 119 is pressed and the data restoration stop is selected, the data restoration is stopped and the restoration information is discarded. On the other hand, in this display state, when the portion corresponding to the “No” display location on the touch panel 119 is pressed and it is selected not to stop the data restoration, as shown in FIG. The user interface screen for allowing the user to select whether or not to perform is displayed.

  The flowchart in FIG. 8 shows an example of the control operation of the control unit 101 when the memory card 115 is removed from the card mounting unit 123 during recording processing and recording of recording data is interrupted.

  First, in step ST1, the control unit 101 starts a control operation, and then proceeds to processing in step ST2. In step ST2, the control unit 101 displays a user interface screen for allowing the user to select whether or not to perform data restoration (see FIG. 7B). Next, in step ST3, the control unit 101 determines whether or not data restoration has been selected. When the portion corresponding to the “Yes” display location on the touch panel 119 is pressed and data restoration is selected, the control unit 101 is removed (extracted) from the card mounting unit 123 in step ST4. Then, a user interface screen that prompts the user to install the memory card 115 as a restoration target is displayed (see FIG. 7C).

  Next, when the user attaches the memory card 115 to the card attachment unit 123 in step ST5, the control unit 101 determines whether or not the attached memory card 115 is a repair target in step ST6. In this case, for example, the control unit 101 determines whether or not it is a repair target based on the ID as individual identification information of the attached memory card 115.

  When the installed memory card 115 is not the restoration target, the control unit 101 displays a user interface screen indicating that the memory card 115 is different from the data restoration target in step ST7 (see FIG. 7D). Thereafter, the process returns to step ST5. On the other hand, when the loaded memory card 115 is a restoration target, in step ST8, a user interface screen for allowing the user to select whether or not to perform data restoration is displayed (see FIG. 7E).

  When the portion corresponding to the display location of “Yes” on the touch panel 119 is pressed and execution of data restoration is selected, the control unit 101 determines in step ST10 as a restoration target attached to the card attachment unit 123. The data restoration process is performed on the memory card 115, and thereafter, in step ST11, the process returns to the photographing standby state (standby mode). On the other hand, when the portion corresponding to the “No” display location on the touch panel 119 is pressed in step ST9 and it is selected not to execute data restoration, the control unit 101 returns to the processing in step ST4 and again restores the restoration target. A user interface screen that prompts the user to install the memory card 115 is displayed (see FIG. 7C).

  When the portion corresponding to the “No” display location on the touch panel 119 is pressed in step ST3 described above and it is selected not to perform data restoration, the control unit 101 cancels data restoration in step ST12. A user interface screen is displayed for the user to confirm (see FIG. 7F).

  Next, in step ST13, the control unit 101 determines whether restoration cancellation has been selected. When the portion corresponding to the display location of “Yes” on the touch panel 119 is pressed and it is selected to cancel the data restoration, the control unit 101 discards the restoration information in step ST14, and then in step ST11. Return to the shooting standby state (standby mode). On the other hand, when the portion corresponding to the “No” display location on the touch panel 119 is pressed and it is selected not to stop the data restoration, the control unit 101 returns to the process of step ST2 and performs data restoration again. A user interface screen for allowing the user to select whether or not is displayed (see FIG. 7B).

  As described above, in the camcorder 100 shown in FIGS. 1 and 2, when the recording of recording data is interrupted by removing the memory card 115 from the card mounting unit 123 during the recording process, the data restoration is performed on the LCD panel 118. A user interface screen for allowing the user to select whether or not to perform is displayed. As a result, the user who has removed the memory card 115 from the card mounting unit 123 is prompted to immediately repair the recording abnormality of the removed memory card 115, and the user can easily recognize the necessity of the repair. However, the possibility of leaving the memory card 115 in an abnormal state can be reduced, and the possibility of using it as it is in another device can be reduced.

  In addition, in the camcorder 100 shown in FIGS. 1 and 2, a protective lid is provided to prevent the memory card 115 from being removed from the card mounting portion 123, and further, the protective lid is prevented from opening during the recording process. Since a locking mechanism or the like is unnecessary, the number of parts is small, the configuration can be simplified, and the cost can be reduced.

  Also, in the camcorder 100 shown in FIGS. 1 and 2, when it is selected to perform data restoration based on a user interface screen for allowing the user to select whether or not to perform data restoration, the card mounting unit 123 An interface screen for guiding the removed memory card 115 to be repaired is displayed. Therefore, the user can easily and reliably remount the memory card 115 removed during the recording process, and can promptly execute data restoration of the memory card 115. In addition, if the memory card 115 that is not the individual to be repaired is installed, the data (restoration information) that remains without being recorded because the data recording is interrupted is not discarded. The possibility of leaving the memory card 115 in an abnormal state can be reduced.

  In the camcorder 100 shown in FIGS. 1 and 2, when a user interface screen for allowing the user to select whether or not to perform data restoration is displayed, whether or not to perform data restoration based on the user interface screen. Is controlled so as not to shift to another operation mode (see FIG. 8), there is a probability that the user who removed the memory card 115 from the card mounting unit 123 will immediately select to perform data restoration. This increases the possibility that the user will leave the recording medium in an abnormal state. In this sense, the control unit 101 constitutes a mode control unit.

  Further, in the camcorder 100 shown in FIGS. 1 and 2, when it is selected not to perform data restoration based on a user interface screen for allowing the user to select whether or not to perform data restoration, data recording is performed. Data (restoration information) remaining without being recorded due to the interruption is discarded. For this reason, the recording unit 114 is in a state where it can normally record to the memory card 115 that is next mounted in the card mounting unit 123 (photographing standby state), and can record without waiting for the time required for data restoration.

  Further, in the camcorder 100 shown in FIGS. 1 and 2, when it is selected not to perform data restoration based on a user interface screen for allowing the user to select whether or not to perform data restoration, the data restoration is stopped. When the user interface screen for making the user confirm is further displayed and it is confirmed that the data restoration is stopped, the data remaining without being recorded because the data recording is interrupted is discarded. In this way, by asking for user confirmation, it is possible to cope with a case where the user erroneously selects not to perform data restoration.

  In the above-described embodiment, the recording medium is the memory card (memory stick) 115. However, the recording medium handled in the present invention is not limited to the memory card, and is attached to and detached from the recording medium mounting portion. Other recording media such as an HDD and an optical disk may be used as long as they are freely mounted and used.

  The present invention can reduce the possibility of a user leaving a recording medium in an abnormal state, and can be applied to, for example, a camcorder that uses a memory card as a recording medium.
