The image data is read from and reproduced.

  The hard disk 15 is a recording medium for recording data, and records captured image data and image data input from the video input terminal 11a. In this embodiment, the data 10 to 41 are recorded in a state of being sorted for each folder corresponding to a total of five groups as shown in FIG. That is, in the lower layer of the upper image folder 20, a total of five group folders 21 to 21 corresponding to the groups set for each type of “travel”, “birthday party”, “athletic party”, “school group”, “unset” are set. 25, and data 10 to 41 are separately recorded for each of the group folders 21 to 25 under the control of the recording / playback processing unit 14.

  Reproduction buttons 5a to 5e are assigned to the group folders 21 to 25 so as to correspond thereto. That is, the “Travel” group folder 21 corresponds to the first play button 5a. Hereinafter, the “Birthday party” group folder 22 is the second play button 5b, and the “Athletic meet” group folder 23 is the third play button. The button 5c, the “Gakugekai” group folder 24 corresponds to the fourth playback button 5d, and the “unset” group folder 25 corresponds to the fifth playback button 5e. The setting of each group and the assignment of each group folder 21 to 25 and each reproduction button 5a to 5e are performed by the system controller 16 as will be described later. The “unset” group folder 25 can set the name of the type related to the group by a required operation on the digital video camera 1.

  As will be described later, each group folder 21 to 25 stores data 10 to 41 in accordance with a group instruction by a pressing operation of the corresponding playback button 5a to 5e, and any one of the playback buttons 5a to 5a. In response to the depressing operation 5e, the data 10-41 recorded in the corresponding group folders 21-25 is read out. For example, when recording data relating to a trip, the user depresses the first playback button 5a, and in accordance with this operation, the image data to be recorded is recorded in the “trip” group folder 21 corresponding to the first playback button 5a. The When the first reproduction button 5a is pressed during data reproduction, the data 10 to 12 recorded in the “travel” group folder 21 are sequentially read and reproduced.

  The system controller 16 corresponds to the above-described setting means for setting a plurality of groups, and performs control related to data recording (hereinafter referred to as a recording mode), control related to data reproduction (hereinafter referred to as a playback mode), and The overall control of the digital video camera 1 including the imaging unit 10 is performed. The system controller 16 is connected to the playback buttons 5a to 5e, the start / stop button 7 for data recording, other buttons and switches (not shown in FIG. 2), the external connection terminal 11c, and the remote control light receiving unit 11d. .

Determine the allocation of ~ 5e. Therefore, the system controller 16 outputs instructions related to data recording and reproduction to the recording / reproduction processing unit 14 and the hard disk 15 based on the contents set and determined in this way.

  Further, the system controller 16 performs control to start the above-described recording mode by receiving a recording start instruction by pressing the start / stop button 7. In this case, the system controller 16 receives a recording instruction (group instruction) for each of the playback buttons 5a to 5e that is pressed down after the start / stop button 7, and thereby the group folder corresponding to each of the pressed down playback buttons 5a to 5e. An instruction signal is output to the recording / playback processing unit 14 so as to record image data in 21 to 25. By outputting this instruction signal, the recording / reproducing processor 14 can record data on the hard disk 15 in association with the type corresponding to the data content. The system controller 16 accepts an instruction by pressing the start / stop button 7 again and ends the recording mode.

  Furthermore, the system controller 16 performs control to start the reproduction mode by receiving a reproduction instruction by pressing any one of the reproduction buttons 5a to 5e. In this case, the system controller 16 outputs an instruction signal to the recording / playback processing unit 14 so as to read the data 10-41 from the group folders 21-25 corresponding to the pressed play buttons 5a-5e. By outputting this instruction signal, the recording / reproducing processor 14 can reproduce data related to the type related to the required group. In the above-described recording mode and playback mode, the system controller 16 displays character data (recording and playback) indicating the operation state of the recording / playback unit 11 and the name of the type related to the processing target group. It also outputs instructions to display.

  Furthermore, the system controller 16 can perform the above-described processing in the recording mode and the reproduction mode in accordance with the signal content received by the remote control light receiving unit 11d and the signal content received by the external connection terminal 11c in addition to the processing described above. ing. The external connection terminal 11c can be connected to various input devices such as a personal computer and a PDA.

  Further, the system controller 16 corresponds to the “unset” fifth reproduction button 5e according to the input content by a button / switch (not shown), the signal content received by the remote control light receiving unit 11d, and the signal content received by the external connection terminal 11c. The name related to the type of the group folder 25 to be set can be set. Further, the system controller 16 instructs the video output unit 17 to display the reproduced image data, and to output the decompressed image data to the outside from the video output terminal 11b.

  The video output unit 17 converts the image data expanded by the compression / expansion unit 13 into a signal conforming to the television format, and outputs the signal to either the display interface unit 18 or the video output terminal 11b based on an instruction from the system controller 16. The display interface unit 18 is connected to the liquid crystal screen 4 shown in FIG. 1 and performs processing for displaying the image data from the video output unit 17 on the liquid crystal screen 4. The display interface unit 18 also performs a process of displaying the display data relating to the operation status and the type name transmitted from the display processing unit 19 on the liquid crystal screen 4 as described later. The digital video camera 1 also allows the user to monitor the image data recorded on the liquid crystal screen 4 by transmitting the image data to be recorded to the video output unit 17 by the compression / decompression unit 13 in the recording mode. It is also possible to do so.

  The display processing unit 19 performs processing for displaying the operation status of the recording / reproducing unit 11 and the name of the type related to the group corresponding to each of the reproduction buttons 5a to 5e on the liquid crystal screen 4, and an internal memory (not shown). A variety of display data such as character data is recorded. For example, the display processing unit 19 performs a process of outputting the operating state character data to the display interface unit 18 based on the instruction output by the system controller 16. By outputting the character data in this way, the “playing” character is displayed on the upper right of the liquid crystal screen 4 in the playback mode. Also, in the recording mode, character data of a type name corresponding to the data content to be recorded is also output. For example, when recording image data related to a school performance, the characters “Recording” and “Gakugekai” Displayed on screen 4.

  Further, when the power switch 8 of the digital video camera 1 is turned on, the display processing unit 19 displays the name of the type at the position of the liquid crystal screen 4 next to the play buttons 5a to 5e as shown in FIG. As described above, the display position is designated and character data relating to the type name is output to the display interface unit 18. By displaying the name in this way, the user can easily check the type related to the group to which each of the playback buttons 5a to 5e is assigned, and at the time of recording and playback, each type corresponding to the type to which the desired data belongs. The playback buttons 5a to 5e can be appropriately operated.

  Next, a recording mode processing procedure for recording image data captured by the digital video camera 1 and a playback mode processing procedure will be described with reference to a first flowchart in FIG. 4 and a second flowchart in FIG.

  First, as shown in the first flowchart of FIG. 4, when the power switch 8 of the digital video camera 1 is turned on (S1), the system controller 16 starts control. As the control is started when the power switch 8 is turned on, the name of the type related to each group is displayed on the liquid crystal screen 4 as shown in FIG. Next, when the user presses down the start / stop button (S2), the processing of the system controller 16 is set to the recording mode (S3).

  In this recording mode, the system controller 16 accepts that one of the first to fifth playback buttons 5a to 5e has been depressed by the user (S4), and identifies the group folders 21 to 25 corresponding to the depression ( S5). For example, when the third playback button 5c is pressed, the system controller 16 specifies the group folder 23 of “athletic meet” shown in FIG. Further, the system controller 16 outputs an instruction signal to the recording / playback processing unit 14 so as to record the image data in the specified group folder 23.

  In the state as described above, when the imaging button 6 is pressed, image data is captured by the imaging unit 10 (S6), and the captured image data is transmitted to the recording / reproducing unit 11. The transmitted image data is compressed by the compression / decompression unit 13 (S7), and the recording / playback processing unit 14 records the image data in the group folder 23 in the hard disk 15 specified by the system controller 16 (S8). By performing such processing for each imaging, the data 10 to 41 are recorded on the hard disk 15 in a grouped state as shown in FIG.

  Next, the processing in the reproduction mode will be described based on the second flowchart of FIG. Note that the second flowchart starts from the state where the power switch 8 is already turned on.

  First, it is accepted that any of the first to fifth playback buttons 5a to 5e has been depressed by the user (S10), and the system controller 16 identifies the group folders 21 to 25 corresponding to the depression (S11). For example, when the fourth play button 5d is pressed, the system controller 16 specifies the group folder 24 of “Gakugeikai” shown in FIG. Further, the system controller 16 instructs the recording / playback processing unit 14 to read out the image data from the specified group folder 24.

  In response to an instruction from the system controller 16, the recording / playback processing unit 14 sequentially reads image data (data 30 to 32) from the specified group folder 23 (S12), and the compression / decompression unit 13 decompresses the read image data. (S13) The image data is reproduced and displayed on the liquid crystal screen 4 via the video output unit 17 and the display interface unit 18 (S14).

  As described above, in the digital video camera 1 according to the present invention, required image data can be reproduced and displayed by simply pressing one of the reproduction buttons 5a to 5e, and an operation of searching for image data to be viewed is unnecessary. In addition, since the operation of searching for image data becomes more difficult as the amount of recorded image data becomes larger, the present invention exhibits superiority as compared with the prior art as more image data is recorded on a recording medium. . Further, since the group type names corresponding to the respective reproduction buttons 5a to 5e are displayed on the liquid crystal screen 4, the user can easily select image data belonging to the group desired by the user only by confirming the display.

  The digital video camera 1 according to the first embodiment is not limited to the above-described form, and various modifications can be applied. For example, the number of the playback buttons 5a to 5e provided on the apparatus main body 2 can be appropriately increased and decreased, and the number of group folders can be set according to the number of playback buttons. In addition to the hard disk, an optical disk such as a CD and a DVD and a semiconductor memory that can be accessed and recorded at random can be applied to the recording medium. Such a recording medium is not limited to the form built in the apparatus main body 2. Alternatively, a configuration in which the recording medium is detached from the apparatus main body 2 is also possible. When an optical disk and a semiconductor memory are applied to the recording medium, it is necessary to provide a processing unit for reading and writing data from / to the recording medium in the apparatus main body 2.

  Furthermore, since the image data can be applied to both still images and moving images, the processing of the first embodiment can also be applied to a digital camera. Furthermore, the group to be set can be appropriately set by the operation of various buttons provided on the apparatus main body 2 or the operation from an external device connected to the external connection terminal 11c. Etc.

  In addition, it is possible to set other types of names related to each group, for example, names such as “Spring”, “Summer”, “Autumn”, and “Winter” can be set according to the shooting time. In addition, groups may be set according to age such as “kindergarten”, “elementary school”, and “junior high school”. What is important is to set a name of a related type according to the contents of the image data recorded by the group. By setting the name in this way, the user can easily determine the type of the image data simply by looking at the name, and further determine which type each playback button 5a to 5e corresponds to from the display location of the name. it can.

  FIG. 6 shows a display unit 23 according to a modification of the first embodiment. The display unit 23 describes the name of the type related to the group to which each of the playback buttons 25a to 25e corresponds to the lower part of each of the playback buttons 25a to 25e provided on the frame unit 23a of the liquid crystal screen 24. Therefore, in this modified example, unlike FIG. 1, the group name is not displayed on the liquid crystal screen 24. Therefore, the processing load of the display processing unit 19 shown in FIG. 2 is reduced, and the apparatus cost is reduced. Since the fifth playback button 25e is not set, it is left blank so that the user can freely write the name.

  FIGS. 7A and 7B show a display unit 33 according to another modification of the first embodiment. The display unit 33 uses a touch panel type liquid crystal screen 34, and is not software playback buttons 5a to 5e as shown in FIG. 1, but software displayed on the liquid crystal screen 34 as shown in FIG. 7B. Each reproduction button 35a to 35e is displayed. When the power switch is turned on, a display button 35x is displayed on the liquid crystal screen 34 as shown in FIG. 7A, and each playback button 35a shown in FIG. 7B is touched by touching the display button 35x.
