When the item L1 is selected by the user, the edited moving image file generated by the moving image editing process is recorded in the recording device 102 in the image editing device 100. When the item L2 is selected by the user, the edited moving image file generated by the moving image editing process is recorded on the recording device 102 in the image editing device 100 and the recording device 200 connected by the communication unit 210. It is recorded (saved) on the medium 207a. The generation button B2 is operated by the user via the input member 106 when instructing generation start of the edited moving image file. When the generation button B2 is operated by the user, the control circuit 101 starts a moving image editing process described later.

  A moving image generation process performed by the control circuit 101 will be described. The moving image generation process includes a setting process, a moving image editing process, and a recording process. Hereinafter, explanation will be made separately for each process.

(1) Setting Process In the setting process, the control circuit 101 selects an image file as a material for generating edited moving image data and selects an effect to be given to the edited moving image data in accordance with a user's selection and setting operation. And selection of audio data to be added to the edited moving image data.
(1-1) Selection of Image File When the activation of the moving image editing application is instructed in accordance with the operation of the input member 106 by the user, the control circuit 101 is shown in FIG. The edit processing screen 150 is displayed. The acquisition unit 101a acquires an image file selected by the user from among the image files recorded on the recording medium 207a attached to the photographing apparatus 200. In this case, the acquisition unit 101a instructs the photographing apparatus 200 to transmit the selected image file via the communication unit 210. Note that the user may operate the input member 106 of the image editing apparatus 100 to select an image file, or the user may operate the input member 201 of the imaging apparatus 200 to select an image file. Good.

  When the image file selected by the user is transmitted from the imaging apparatus 200, the recording control unit 101c records the transmitted image file in the recording apparatus 102. An image file is recorded in the recording device 102. The control circuit 101 displays the image file stored in the memory 105 and the file name and thumbnail image of the image file recorded in advance in the recording device 102 in the image registration area R1 of the edit processing screen 150.

(1-2) Selection of Effect The user operates the input member 106 in the style selection area R2 on the editing process screen 150 to select the effect of the edited moving image data to be generated. The control circuit 101 sets the effect selected by the user as the selected effect, and displays the selected effect in the style selection area R2 of the editing process screen 150. When the moving image generation button B1 is operated, the control circuit 101 causes the editing unit 101b described later to generate edited moving image data corresponding to the selected effect.

(1-3) Selection of Audio Data The user can add desired audio data as BGM to the edited moving image data from the audio data recorded in the recording device 102. In this case, the control circuit 101 a reads out the audio data selected by the user from the audio data recorded in the recording device 102 and stores it in the memory 105. When the audio data is stored in the memory 105, the control circuit 101 displays the file name of the audio data stored in the memory 105 in the music registration area R3 of the edit processing screen 150. It is assumed that audio data can be selected by the user operating the input member 106 of the image editing apparatus 100. The audio data selected by the user may be acquired from an external device or the Internet via the external interface 108.

(2) Moving Image Editing Process When the moving image generation button B1 on the edit selection screen 150 is operated by the user via the input member 106, the editing unit 101b starts the moving image editing process. The editing unit 101b generates edited moving image data by, for example, a well-known rendering process, using the image data, effect, and audio data of the image file selected in the setting process described above. In this case, the editing unit 101b reads the image file recorded in the recording device 102 into the memory 105, and decompresses the image data of the image file, that is, the compressed image data. Then, the editing unit 101b generates edited moving image data by combining the decompressed image data and audio data, and generating a moving image stream by rendering processing. At this time, the editing unit 101b adds effects such as fade-in and fade-out according to the selected effect.

(3) Recording Process The recording control unit 101c performs a compression process on the generated edited moving image data. In this case, the recording control unit 101c performs different compression processing according to the item L1 or L2 selected in the moving image generation dialog 151. Hereinafter, the case where the item “Save File” of the item L1 is selected and the case where the “write back to camera (memory card)” of the item L2 is selected will be described separately.

(3-1) File Save When “File Save” in the item L1 is selected, the recording control unit 101c compresses the generated edited moving image data in a format that can be reproduced on the monitor 104 of the image editing apparatus 100. To generate an edited movie file. In this case, the recording control unit 101c sets various control parameters of the edited moving image data using the compression parameters corresponding to the image editing apparatus 100 so that the format conforms to the image editing apparatus 100. Since the generated edited moving image file is compressed in a format optimal for the image editing apparatus 100, it cannot be played back by the photographing apparatus 200. Then, the recording control unit 101c records (saves) the generated edited moving image file in the recording device 102.

(3-2) Write Back to Camera (Recording Medium) When “Write Back to Camera (Recording Medium)” in the item L2 is selected, the recording control unit 101c captures the generated edited moving image data with the photographing apparatus 200. Compression processing is performed in a format that can be reproduced on the monitor (not shown) and a format that can be reproduced on the monitor 104 of the image editing apparatus 100 to generate an edited moving image file. The recording control unit 101c records the edited moving image file generated by the compression process in the photographing apparatus 200 (for example, the recording medium 207a) and the recording apparatus 102 of the image editing apparatus 100. In this case, the recording control unit 101c sets various control parameters of the edited moving image data using compression parameters that are optimal for each device so that the format is suitable for the photographing apparatus 200 or the image editing apparatus 100. An edited moving image file for the image editing device 100 and an edited moving image file for the photographing device 200 are generated. Then, the recording control unit 101c records (saves) the generated edited moving image file for the image editing apparatus 100 in the recording apparatus 102. Further, the recording control unit 101 c transmits the edited moving image file for the photographing apparatus 200 generated in a format corresponding to the photographing apparatus 200 to the photographing apparatus 200 via the communication unit 210, and a recording medium connected to the photographing apparatus 200 207a is recorded.

  Note that the recording control unit 101c may simultaneously perform the compression processing of the edited moving image file for the image editing device 100 and the compression processing of the edited moving image file for the photographing device 200. Alternatively, the recording control unit 101c may simultaneously start recording the edited moving image file for the shooting device 200 on the shooting device 200 and recording the edited moving image file for the image editing device 100 on the recording device 102. The recording control unit 101c may start the compression processing of the edited moving image file for the image editing device 100 by causing the shooting device 200 to record the generated editing moving image file for the shooting device 200. Furthermore, it is only necessary that the user can set whether or not to start recording from the photographing apparatus 200 or the recording apparatus 102 by performing a predetermined operation on the edit selection screen 105 by the user. The generated edited moving image file may be configured to be recorded on a recording medium 207 a connected to the recording medium interface 107 in addition to the photographing apparatus 200 and the recording apparatus 102.

  The operation of the image editing apparatus 100 will be described using the flowchart shown in FIG. A program for performing the processing of FIG. 4 is stored in the recording apparatus 102, and is activated and executed by the control circuit 101 when the image editing application is activated in response to a user operation.

  In step S1, the acquisition unit 101a instructs the photographing apparatus 200 to transmit the image file selected by the user. Then, the acquisition unit 101a acquires the selected image file and records it in the recording device 102. When an image file transmitted and recorded from the image capturing apparatus 200 and an image file stored in advance in the recording apparatus 102 are read and an image file to be used for generating edited moving image data is selected by the user, the process is performed. Proceed to S2. In step S2, the control circuit 101 sets the effect selected by the user as the selected effect, and proceeds to step S3. In step S3, the control circuit 101 reads out the audio data selected by the user from the recording device 102, stores it in the memory 105, and proceeds to step S4.

  In step S4, it is determined whether or not the user has instructed the generation start of edited moving image data. When the moving image generation button B1 is operated through the input member 106 by the user, the control circuit 101 makes a positive determination in step S4 and proceeds to step S5. If the moving image generation button B1 has not been operated, the control circuit 101 makes a negative determination in step S4 and returns to step S1. In step S5, the editing unit 101b reads the image file recorded in the recording device 102 into the memory 105, decompresses the image data of the read image file, and proceeds to step S6. In step S6, the editing unit 101b generates edited moving image data by combining the decompressed image data and audio data according to the selected effect, and proceeds to step S7.

  In step S <b> 7, the control circuit 101 determines whether or not “Save File” of the item L <b> 1 is selected by the user in the moving image generation dialog 151. If “Save File” of item L1 is selected, step S7 is affirmed by the control circuit 101, and the process proceeds to step S8. In step S8, the recording control unit 101c performs a compression process so that the edited moving image data can be reproduced by the image editing device 100, that is, the editing moving image for the image editing device 100 using the compression parameters of the image editing device 100. A file is generated and the process proceeds to step S9. In step S9, the recording control unit 101c records the generated edited moving image file for the image editing apparatus 100 in the recording apparatus 102 and ends the process.

  When the item “L2 write back to camera (recording medium)” is selected, the control circuit 101 makes a negative determination in step S7 and proceeds to step S10. In step S10, the recording control unit 101c performs a compression process suitable for reproduction on the edited moving image data by the shooting device 200 to generate an edited moving image file for the shooting device 200, and the image editing device 100 for the edited moving image data. A compression process suitable for reproduction is performed to generate an edited moving image file for the image editing apparatus 100, and the process proceeds to step S11. In step S11, the recording control unit 101c records the generated edited moving image file for the image editing device 100 in the recording device 102, and records the generated editing moving image file for the shooting device 200 in the recording medium 207a attached to the shooting device 200. To finish the process.

According to the image editing apparatus 100 according to the embodiment described above, the following operational effects can be obtained.
The image editing apparatus 100 according to the present embodiment is configured to be able to edit a moving image file shot by an external device such as the shooting apparatus 200 and write it back to the shooting apparatus 200. The image editing apparatus 100 includes a control circuit 101 and a recording apparatus 102. The control circuit 101 functionally includes an acquisition unit 101a, an editing unit 101b, and a recording control unit 101c. The acquisition unit 101a acquires an image file from the imaging apparatus 200 via the external interface 108. The recording device 102 records the image file acquired by the acquisition unit 101a. The editing unit 101b edits the image data recorded by the recording device 102 to generate edited moving image data. The recording control unit 101c generates edited moving image files according to the compression parameters corresponding to the photographing device 200 and the image editing device 100, and records the edited moving image data generated by the editing unit 101b, respectively. That is, the recording control unit 101c uses the common edited moving image data to generate the edited moving image file corresponding to the photographing device 200 and the image editing device 100 to be recorded, in other words, up to the moving image editing process. Processing time has been shortened.

  In the conventional technology, when the generated edited moving image file is recorded in the photographing device 200 and the image editing device 100, the edited moving image data is generated by separate processing and the edited moving image file is generated by performing compression processing. There was a need. That is, the user needs to separately perform an operation for instructing the moving image generation process, and the moving image editing process is performed for writing back to the image capturing apparatus 200 and recording to the image editing apparatus 100, respectively. On the other hand, according to the present embodiment, the edited moving image data is generated by the common moving image editing process by the editing unit 101b for writing back to the photographing device 200 and recording to the image editing device 100. That is, since a plurality of moving image editing processes are not required, the time required for the moving image generating process can be shortened. Furthermore, the user can write back to the image capturing apparatus 200 and record to the image editing apparatus 100 in response to a single moving image generation processing instruction, so that convenience can be improved.

The embodiment described above can be modified as follows.
(1) At the time of writing back, the recording control unit 101c performs a compression process suitable for reproduction by the photographing apparatus 200 on the edited moving image data to generate an edited moving image file for the photographing apparatus 200. In addition to recording on the recording medium 207 a, the edited moving image file for the photographing apparatus 200 may be recorded on the recording apparatus 102 in the image editing apparatus 100. In the image editing apparatus 100 having high versatility at the time of reproduction, an image editing file subjected to compression processing suitable for a device having low versatility of reproduction may be stored. In this case, the compression moving image data generated by the moving image editing process is only subjected to a single compression process. As a result, the processing time required for the moving image generation process can be shortened.

(2) Although the control circuit 101 has been described as acquiring image data from the image capturing apparatus 200 connected by the communication unit 210 and writing back the generated edited moving image file, the control circuit 101 starts from the recording medium 207a via the recording medium interface 107. Image data may be acquired, and the generated edited moving image file may be written back.

(3) The image editing apparatus 100 may write back to an apparatus other than the photographing apparatus 200, such as a smartphone or a photo frame, as long as it can reproduce a moving image. In this case, a device to be written back can be selected in the moving image generation dialog 151. The recording control unit 101c may generate an edited moving image file using the compression parameters of each external device according to the device characteristics of the external device for the generated edited moving image data. The image editing apparatus 100 may be able to write back to a plurality of devices connected via the communication unit 210.

  In addition, the present invention is not limited to the above-described embodiment as long as the characteristics of the present invention are not impaired, and other forms conceivable within the scope of the technical idea of the present invention are also within the scope of the present invention. included. The embodiments and modifications used for the description may be configured by appropriately combining them.
