The mobile terminal transmits the input additional information to a camcorder, according to a transfer instruction. While neither recording nor reproduction is performed, the camcorder associates the additional information from the mobile terminal, with a last recorded image when the last recorded image is not evaluated, and with a next image to be recorded when the last recorded image has been evaluated.

## Background
BACKGROUND
Field
Aspects of the present invention relate to an electronic device which associates additional information with content and a control method for the same.
Description of the Related Art
In recent years, a small and light electronic imaging apparatus such as a digital still camera or a digital video camera for recording captured images in a memory card has been widely spread. Such an electronic imaging apparatus is configured to not only record a captured image but also record various additional information in association with the captured image (Japanese Patent Laid-Open No. 2004-273076). Such additional information includes text information, such as photographer information, shooting location information, and comments, in addition to shooting condition information, and is used as for example information for searching for a target image in editing operation.
Further, an electronic imaging apparatus having versatile communication means for wireless LAN or the like is also available in the market, and a personal computer (PC), or a personal digital assistant such as a tablet PC or a smartphone can access the electronic imaging apparatus. Japanese Patent Laid-Open No. 2003-188950 describes transmission of additional information edited using for example a tablet PC or a smartphone to an imaging apparatus using wireless communication. In the technique described in Japanese Patent Laid-Open No. 2003-188950, a user of an imaging apparatus selectively adds the transferred additional information to a recorded captured image, or to an image to be captured.
Japanese Patent Laid-Open No. 2013-098658 describes transferring of additional information to an imaging apparatus after selection and designation of an image (recorded captured image or image to be captured) with which the additional information is to be associated on tablet PC. Selection of the image with which the additional information, is to be associated is performed on the imaging apparatus, in the technique described, in Japanese Patent Laid-Open No. 2003-188950, and on the tablet PC, in the technique described in Japanese Patent Laid-Open. No. 2013-098658. This selection operation usually requires an instruction button providing instructions for selection of a recorded image or a future image to be recorded. In the personal digital assistant having a small screen, such as a smartphone, arrangement of such an instruction button is often made difficult. Even if a tablet PC having a screen of a certain size is employed, such an instruction button is preferably removed, in consideration of a relationship with other elements desired to be arranged. In addition, even if there is no problem of the size of the screen, a user needs to perform additional instruction operation (operation another button) depending on recording the additional information in the recorded image or in the future image to be recorded, and the additional instruction operation causes trouble. The problems may be similarly caused upon adding the additional information to content such as an audio file or a document file, in addition to adding the additional information to the image.
SUMMARY
An aspect of the present invention is to offer an electronic device for associating additional information with desired content with a further simple operation, and a control method for the same.
According to one embodiment, an electronic device includes an acquisition unit configured to acquire evaluation information having been associated with recorded content, an input unit configured to input additional information for content, and a control unit configured to perform control to record additional information input from the input unit to be associated with the recorded content, upon not acquiring evaluation information representing that the recorded content has been evaluated, by the acquisition unit, and record additional information input from the input unit to be associated with not the recorded content but content to be recorded, upon acquiring evaluation information representing that the recorded content has been evaluated, by the acquisition unit.

Embodiments of the present invention will be described below in detail with reference to the drawings.
First Embodiment
FIG. 1 is a block diagram illustrating a schematic configuration of a system to which an electronic device according to an embodiment of the present invention is applied. The present system includes a digital video camera (camcorder) 10 obtained by integrating a video camera with an image recording device, and a mobile terminal 50 for inputting additional information to be recorded as metadata into a camcorder 10, in association with an image. The mobile terminal 50 is connected to the camcorder 10 through wireless communication such as WiFi® or Bluetooth®. The mobile terminal 50 is for example a portable PC, a tablet PC, or a smartphone, can operate the camcorder 10, and further can edit additional information, transfer the additional information to the camcorder 10, and designate an image with which the additional information is to be associated. The mobile terminal 50 can further acquire information representing whether the camcorder 10 is performing recording, from the camcorder 10, and below-mentioned evaluation information for an image recorded the camcorder 10.
A configuration of the camcorder 10 is described here. A control unit 12 totally controls a system of the camcorder 10. The control unit 12 loads a program stored in a ROM 14 into a RAM 16 and executes the program to control component units. The ROM 14 is a non-volatile data storage unit, and stores control programs executed by the control unit 12 and fixed data.
The RAM 16 is a volatile data storage unit temporary storing various data. The RAM 16 is used as a working memory of the control unit 12, a working area for compression/decompression processing by an image compression/decompression unit 28, and a VRAM for temporarily storing image data displayed on a display unit 18. The RAM 16 is also used as a unit for temporarily storing the additional information received from the mobile terminal 50 through a wireless communication unit 62 to associate the additional information with a captured image.
An imaging unit 24 as an image input unit has an imaging lens (including zoom lens and focus lens) and an image sensor, images an object based on the control by the control unit 12, and outputs image data constituting a still image or a motion image. An image processing unit 26 performs image processing, such as pixel interpolation, resizing, and color conversion processing, on the image data output from the imaging unit 24. Furthermore, the image processing unit 26 calculates data required to control focus, exposure, and color balance of the imaging unit 24, based on the image data from the imaging unit 24, and supplies a result of the calculation to the control unit 12. The control unit 12 uses this calculation result from the image processing unit 26 to control focus, exposure, and automatic white balance of the imaging unit 24.
The image compression/decompression unit 28 compresses the image data subjected to the image processing in the image processing unit 26, and decompresses compressed image data (e.g., compressed image data read from a recording medium 32).
The display unit 18 displays for example various settings, an image captured by the imaging unit 24, and an image read from the recording medium 32 and reproduced, based on the control by the control unit 12. The display unit 18 is constituted as a display in a viewfinder and/or a liquid crystal monitor having variable angle.
The camcorder 10 has a recording medium I/F 30 to and from which the recording medium 32 such as a memory card can be mounted and dismounted. The recording medium I/F 30 records and reproduces the compressed image data in and from the recording medium 32, and also records and reproduces additional information associated with the images. The recording medium 32 records captured images as described below, and when a captured image has additional information, the recording medium 32 records the additional information in association with the captured image.
In the present embodiment, each captured image can be associated with the evaluation information representing evaluation of the captured image. The evaluation information may be recorded, as part of attribute information representing attributes of a corresponding image, in a management file associated with the captured image, or in a header portion of an image file. The evaluation information (or attribute information) may be recorded as part of the additional information, in a place or a file recording the additional information.
In the present embodiment, the evaluation information is binary information taking a value of “no evaluation” or “evaluation OK”, for easy recognition, but of course may multivalued information representing multistep evaluation. The camcorder 10 associates the evaluation information of “no evaluation” with the captured image immediately after capture, as default. After shooting or reproduction, a user can operate the camcorder or the mobile terminal 50 to change the evaluation information to “evaluation OK”. “Evaluation OK” also has a protection function, and the camcorder 10 rejects user's delete instruction for captured image having the evaluation information “evaluation OK”. The user needs to change the evaluation information to “no evaluation” before delete operation to delete the captured image having the evaluation information “evaluation OK”.
An operation unit 20 is an input device for receiving user's operation, and includes a power switch for turning on/off the camcorder 10, a shooting start button, a mode switching button for switching an operation mode such as a camera mode (shooting mode) or a reproduction mode, and the like. The operation unit 20 further includes a touch panel disposed to be overlaid on a display screen of the display unit 18 to output two-dimensional coordinate values according to a user's touch position.
Here, touching the touch panel using a finger or a stylus pen (hereinafter, referred to as “finger” for short) is called “touch-down”. A state in contact with the touch panel using the finger is called “touch-on”. Movement of the finger while in contact with the touch panel is called “move”. Operation of removing the finger being in contact with the touch panel from the touch panel is called “touch-up”. A state in which there is nothing in contact with the touch panel is called “touch-off”. The control unit 12 detects these operations on the touch panel, acquires positional coordinates of a position on the touch panel at which the touch panel is in contact with the finger or the and determines which operation is performed on the touch panel. For the move, the control unit 12 can also determine a moving direction of the finger or the pen moving on the touch pan, based on a change in positional coordinates, for each of a vertical component and a horizontal component on the touch panel.
Sequential performance of the touch-down, the move over a certain distance, and the touch-up is defined as a stroke. Quick stroke operation is called flick. The flick is operation of quickly moving the finger while in contact with the touch panel over a certain distance and then removing the finger from the touch panel, in other words, operation of quickly moving the finger on the touch panel as if to swipe. When the move over a predetermined distance or more at a predetermined speed or more detected followed by detection of the touch-up, it can be determined that the flick has been performed. Furthermore, when the move over a predetermined distance or more at speed less than the predetermined speed is detected, it is determined that drag has been performed.
The touch panel includes various touch panels, such as resistive, capacitance, surface acoustic wave, infrared, electromagnetic induction, image recognition, and optical sensor touch panels, and any of them may be used.
A wireless communication unit 22 wirelessly communicates with an external device (here, the mobile terminal 50) having a corresponding communication unit, based on the control by the control unit 12, to transmit/receive various data including image data and character data, and control signals for various operations. For example, a wireless LAN or various near field radio communication systems are practically used therefor.
A configuration of the mobile terminal 50 is described here. A control unit 52 totally controls a system of the mobile terminal 50. The control unit 52 loads a program stored in a ROM 54 into a RAM 56 and executes the program to control component units. The ROM 54 is a non-volatile data storage unit, and stores control programs executed by the control unit 52 and fixed data. The RAM 56 is a volatile storage unit used as a working memory of the control unit 52.
A display unit 58 displays various settings and an image received from the camcorder 10, based on the control by the control unit 52.
An operation unit 60 is an input device for receiving user's operation, and includes a power switch for turning on/off the mobile terminal 50, and a touch panel. This touch panel has functions the same as those of the camcorder 10.
The wireless communication unit 62 wirelessly communicates with the wireless communication unit 22 of the camcorder 10, based on the control by the control unit 52, to transmit/receive various data including image data and character data, and control signals for various operations.
FIG. 2 is a flowchart of operation in a camera mode (shooting mode) of the camcorder 10. The control unit 12 loads a program stored in the ROM 14 into the RAM 16 and executes the program to achieve processing operations in the flowchart of FIG. 2. When the user selects a camera mode using the mode switching button of the operation unit 20, the control unit 12 starts the processing illustrated in FIG. 2.
In S200, the control unit 12 generates control information to be transmitted to the mobile terminal 50, according to settings of the camcorder 10. The control information represents a control state or an operation state of the camcorder 10, and includes operation mode information indicating the camera mode, the reproduction mode, a mode for reproduction performed in the camera mode (REC review mode), and the like. The control unit 12 monitors the camcorder 10 at specific intervals to obtain information for the control information, and stores the information in the RAM 16.
In S201, control unit 12 transmits the control information generated in S200 and stored in the RAM 16 to the mobile terminal 50, through the wireless communication unit 22.
In S202, the control unit 12 receives command and setting data for the camcorder 10 from the mobile terminal 50, through the wireless communication unit 22. The control unit 12 stores the data received at the wireless communication unit 22, in the RAM 16. The command received here is an instruction command for applying the setting data (additional information) received from the mobile terminal 50 as additional information to be associated with clip data.
In S203, the control unit 12 determines whether the camcorder 10 is performing recording. The control unit 12 determines, as the recording, for example a series of processing of output of captured image data from the imaging unit 24, image processing by the image processing unit 26, compression processing by the image compression/decompression unit 28, and recording to the recording medium 32. Clip data recorded in the recording medium 32 is not limited to motion image data, and may be still image data. When the recording is being performed in the camcorder 10, the control unit 12 proceeds to S204, and when the recording is not being performed in the camcorder 10, the control unit 12 proceeds to S207.
In S204, the control unit 12 updates the additional information currently set in the camcorder 10, stored in the RAM 16, with the setting data received in S202, and proceeds to S205. In S205, the control unit 12 determines whether the camcorder 10 stops the recording. For example, when a shooting stop button included in the operation unit 20 provides instructions for stopping the recording of motion image data, the camcorder 10 tops recording. When the camcorder 10 stops the recording, the control unit 12 proceeds to S206, and when the camcorder 10 does not stop the recording, the control unit 12 returns to S200 and repeats the processing in S200 and subsequent steps.
In S206, the control unit 12 updates additional information having been associated with captured clips. Data of the captured clips and the additional information having been associated with the data are recorded in the recording medium 32. The additional information having been associated with the captured clips recorded in the recording medium 32 is updated with the additional information recorded in the RAM 16. For example, when motion image clips are recorded to be stored in different folders, respectively, additional information is stored, as an xml file, in the same folder storing a clip with which the additional information is associated, and the additional information is associated with the clip. Association is not limited to this method, and the additional information may be recorded in a file having a file name with the same extension name as that of a file of a motion image clip with which the additional information is associated. Further, information (file name or the like) specifying the motion image with which the additional information is associated may be added in a header of the file of the additional information. Still further, information (file name or the like) specifying the file of the additional information to be associated with the motion image may be added in a header of a file of the motion image with which the additional information is associated. Still another further, the additional information may be directly recorded in the header of the file of the motion image (additional information may be recorded in the file itself of the motion image).
In S207, the control unit 12 checks whether clip data is recorded in the recording medium 32, through the recording medium I/F 30. When a clip is recorded, the control unit 12 proceeds to S208, and when the clip is not recorded, the control unit 12 proceeds to S211.
In S208, the control unit 12 analyzes the evaluation information of the recorded clip in the recording medium 32, through a recording medium I/F 30, and determines whether the evaluation information represents the “evaluation OK”. When the evaluation information represents the “evaluation OK”, the control unit 12 proceeds to S211. When the evaluation information does not represent the “evaluation OK”, (“no evaluation”), the control unit 12 proceeds to S209.
Rewriting of the evaluation information is briefly described here. The user can use the operation unit 20 of the camcorder 10 or operate the mobile terminal 50 to provide instructions for rewriting the evaluation information to the camcorder 10. When detecting the instructions for rewriting to the “evaluation. OK”, the control unit 12 updates the evaluation information of the recorded clip to have the “evaluation OK” through the recording medium I/F 30, and the evaluation information is rewritten.
The evaluation information may include other evaluation, for example, “evaluation NG” in addition to the “evaluation OK” and “no evaluation”. In such a configuration, the motion image clip evaluated as the “evaluation NG” is considered to have been evaluated, although it is not evaluated as the “evaluation OK”, and new additional information is not to be applied to the motion image clip evaluated as the “evaluation NG”. This is because the evaluated clip is considered to be no longer an object to be evaluated. Therefore, for processing such ternary evaluation information, when the evaluation information represents the “evaluation OK” or “evaluation NG” in S208, the control unit 12 proceeds to S211, and otherwise (“no evaluation”), the control unit 12 proceeds to S209.
An evaluation value having an intermediate value between the “evaluation OK” and the “evaluation NG” may be set. For example, rating information, as a kind of attribute information, having several ranks may be employed for the evaluation information. The user can apply any value of for example five ranks to any of clips. When the user does not apply any of the values, a value “3” (intermediate value) is applied as a default. In this configuration, when any rating value other than “3” is applied in S208, the control unit 12 proceeds to S211, and otherwise (“3”), control unit 12 proceeds to S209. When the rating information has at least three ranks, the intermediate value is applied as the default, and evaluation is determined not to be performed.
In S209, the control unit 12 updates, similarly to S204, the additional information currently set in the camcorder 10, using the additional information received in S202.
In S210, the control unit 12 updates the additional information having been associated with the last recorded clip data of clip data recorded in the recording medium 32, with the additional information in the RAM 16, and proceeds to S212.
In S211, the control unit 12 updates, similarly to S204, the additional information currently set in the camcorder 10 with the additional information received in S202, and proceeds to S212. In this configuration, the additional information being associated with recorded clip data is not updated, and the updated additional information set in the camcorder 10 is associated with a clip subsequently captured.
In S212, the control unit 12 determines whether the camcorder 10 starts recording a captured image. When the camcorder 10 starts the recording, the control unit 12 proceeds to S213, and when the camcorder 10 does not start the recording, the control unit 12 returns to S200 and repeats the processing in S200 and subsequent steps.
In S213, the control unit 12 associates the additional information recorded in the RAM 16 with new clip data being captured and records the additional information in the recording medium 32. That is, the control unit 12 generates a new folder for storing a motion image file generated by newly started imaging to record data of a motion image being captured, and records, in the same folder, the additional information recorded in the RAM 16.
FIG. 3 is a diagram illustrating an example of a user interface (UI) of a Web application for creating data transmitted by the mobile terminal 50 to the camcorder 10, in S202. The control unit 52 of the mobile terminal 50 loads a program stored in the ROM 54 into the RAM 56 and executes the program to achieve this application. The UI 300 illustrated in FIG. 3 is displayed on the display unit 58. The control unit 52 receives user's operation of the operation unit 60, and displays response to the user's operation on the display unit 58. The control unit 52 stores data (additional information) input by the user through the operation unit 60, in the RAM 56, and wirelessly transmits the data to the camcorder 10. The camcorder 10 receives the data transmitted from the mobile terminal 50 in S202. In addition to the shooting condition information, the photographer information, shooting location information, the text information representing a shooting content, or the like can be input as the additional information. As the text information representing the shooting content, the user can input any character string, but for example, information for retrieval of a target image upon editorial operation, explanation comment for a scene of the clip, or information about a cast is input.
The UI 300 of the Web application includes a clip title edit box 301, a photographer name edit box 302, a shooting location edit box 303, a shooting content edit box 304, and a transfer button 305. The control unit 52 stores contents input into the edit boxes 301 to 304 in the RAM 56. When the user of the mobile terminal 50 presses the transfer button 305, the control unit 52 transfers, to the camcorder 10, the contents (additional information) input into the edit boxes 301 to 304, and a command for associating the additional information with clip data, through the wireless communication unit 62.
As described above, in the present embodiment, clip data with which the additional information is associated is changed depending on the operation state of the camcorder 10. Thus, the user does not need to particularly designate the object with which the additional information is to be associated.
Second Embodiment
FIG. 4 is a flowchart illustrating control operation allowing update of additional information of arbitrary recorded clip data in the recording medium 32. Processing in S400 to S413 corresponds to processing in S200 to S213 of the flowchart illustrated in FIG. 2, and processing in S414 to S416 is added to the flowchart illustrated in FIG. 2. That is, in the flowchart illustrated in FIG. 4, S414 to S416 are inserted between S207 and S208 of the flowchart illustrated in FIG. 2
A control program for achieving the operation illustrated in FIG. 4 is stored in the ROM 14, and the control unit 12 loads the control program read from the ROM into the RAM 16 and executes the control program to achieve the control operation illustrated in FIG. 4. When the user selects the camera mode using the mode switching button of the operation unit 20, the control unit 12 starts the processing illustrated in FIG. 4.
Processing operations in S400 to S406 correspond to those in S200 to S206, respectively, and description thereof will be omitted.
When clip data is recorded in the recording medium 32 in S407, the control unit 12 proceeds to S414, and otherwise or when clip data is not recorded, the control unit 12 proceeds to S411.
In S414, the control unit 12 determines whether clip data recorded in the recording medium 32 is being reproduced. When clip data is being reproduced, the control unit 12 proceeds to S415, and when clip data is not being reproduced, the control unit 12 proceeds to S408. When clip data is being reproduced, the control unit 12 reads clip data from the recording medium 32 through the recording medium I/F 30, loads the clip data into the RAM 16, decompresses compressed data in the RAM 16, using the image compression/decompression unit 28, and outputs an image reproduced thereby to the display unit 18. Reproduction in S414 may include image reproduction using REC review to reproduce clip data in a camera mode, or normal image reproduction in a reproduction mode.
In S415, the control unit 12 updates, similarly to S204, the additional information currently set in the camcorder 10 with the additional information received in S402, and proceeds to S416. In S416, the control unit 12 updates additional information having been associated with the clip data recorded in the recording medium 32 and being currently reproduced. The clip being currently reproduced, and the additional information having been associated with the clip are recorded in the recording medium 32. The control unit 12 updates the additional information having been associated with the clip being currently reproduced, and recorded in the recording medium 32, with the additional information in the RAM 16. After the processing in S416, the control unit 12 returns to S400, and repeats the processing in S400 and subsequent steps.
Processing operations in S108 to S413 correspond to those in S208 to S213, respectively, and description thereof will be omitted.
In the control operation illustrated in FIG. 4, while the camcorder 10 reproduces a recorded clip, additional information having new contents is transmitted from the mobile terminal 50 to the camcorder 10, and the additional information of clip data being reproduced can be updated. Therefore, the additional information of any recorded clip can be updated with a simple operation.
Third Embodiment
Description will be made of controlling for automatic selection or determination of a clip in the camcorder 10 to which additional information is to be added, based on recorded evaluation information, in the mobile terminal 50. FIG. 5 is a flowchart illustrating operation of the mobile terminal, and FIG. 6 is a flowchart illustrating operation of the camcorder 10. A control program for achieving the operation illustrated in FIG. 5 is stored in the ROM 54, and the control unit 52 loads the control program read from the ROM 54 into the RAM 56 and executes the program to achieve control operation illustrated in FIG. 5. Similarly, a control program for achieving the operation illustrated in FIG. 6 is stored in the ROM 14, and the control unit 12 loads the control program read from the ROM 14 into the RAM 16 and executes the control program to achieve control operation illustrated in FIG. 6.
The operation of the mobile terminal 50 will be described with reference to FIG. 5. The control unit 52 waits for operation of the user of the mobile terminal 50 to fill the edit boxes 301 to 304 and press the transfer button 305, in the UI 300 illustrated in FIG. 3.
In S500, the control unit 52 determines whether user's operation of the operation unit 60 is operation for requesting the camcorder 10 to transmit additional information to be associated with clip data (pressing of the transfer button 305). When the operation requests to transmit additional information, the control unit 52 proceeds to S501, and when the operation does not request to transmit additional information, the control unit 52 finishes the flowchart illustrated in FIG. 5.
In S501, the control unit 52 determines whether recording operation is being performed in the camcorder 10. When the recording is being performed in the camcorder 10, the control unit 52 proceeds to S502, and when the recording is not being performed in the camcorder 10, the control unit 52 proceeds to S503.
In S502, the control unit 52 transmits to the camcorder 10 a command for requesting addition of the information input into the edit boxes 301 to 304 as additional information, to the clip data being recorded. The information input into the edit boxes 301 to 403 by the user's operation of the operation unit 60 are stored in the RAM 56.
In S503, the control unit 52 determines whether clip data is recorded in the recording medium 32 of the camcorder 10. When clip data is recorded, the control unit 52 proceeds to S504, and when clip data is not recorded, the control unit 52 proceeds to S508.
In S504, the control unit 52 determines whether the camcorder 10 is reproducing clip data. When clip data is being reproduced, the control unit 52 proceeds to S505, and when clip data is not being reproduced, the control unit 52 proceeds to S506. In S505, the control unit 52 transmits to the camcorder 10 a command for requesting addition of the information input into the edit boxes 301 to 304 as additional information, to the clip data being reproduced.
In S506, the mobile terminal 50 requests the evaluation information of the last captured clip from the camcorder 10. The camcorder 10 analyzes the evaluation information of the last captured clip recorded in the recording medium 32, through the recording medium IF 30, and transmits the evaluation information to the mobile terminal 50. The following processing is similar to S208. When the evaluation information represents the “evaluation OK”, the control unit 52 proceeds to S508, and otherwise, the control unit 52 proceeds to S507.
In S507, the control unit 52 transmits to the camcorder 10 a command for requesting addition of the information input into the edit boxes 301 to 304 as additional information, to the last captured clip data.
In S508, the control unit 52 transmits to the camcorder 10 a command for requesting addition of the information input into the edit boxes 301 to 304 as additional information, to clip data of an image to be captured.
After S502, S505, S507, and S508, the control unit 52 finishes the flowchart illustrated in FIG. 5.
