Description

  The present invention relates to a recording apparatus.

  Conventionally, there has been proposed a video camera having a function of giving a special effect when a moving image is reproduced by switching the frame rate (the number of frames per unit time) of the moving image to be photographed.

  For example, by reproducing a moving image shot and recorded at a frame rate of 60 frames per second (fps) at a frame rate of 30 fps, a half-speed slow motion moving image can be reproduced. As a result, it is possible to reproduce a moving image with a smoother subject movement compared to a case where a moving image shot at a frame rate of 30 frames / second is slowly reproduced at half speed.

  Conversely, by playing back a moving image shot and recorded at a frame rate of 15 fps at a frame rate of 30 fps, a double-speed fast-forward moving image can be played. In this manner, special effects can be added so that various moving image reproduction speeds can be obtained depending on the relationship between the frame rate at the time of shooting a moving image and the frame rate at the time of reproduction. In addition, a configuration for changing the frame rate during recording of a moving image has been proposed (see Patent Document 1).

JP 2006-352581

  As described above, when a moving image is shot with the frame rate arbitrarily changed, the playback time of the moving image is determined by the frame rate at the time of shooting and the frame rate at the time of playback.

  For example, consider a case where a 10-second movie is shot and played back at 30 fps. When the frame rate of the moving image at the time of shooting is 60 fps, the playback time is 20 seconds. On the other hand, when the frame rate of the moving image at the time of shooting is 15 fps, the playback time is 5 seconds. Thus, even when a moving image is shot for the same time, the playback time varies depending on the frame rate of shooting and playback of the moving image.

  For this reason, it is conceivable that the playback time of one scene is too short than the user thinks, or conversely, it is too long. In particular, when the user changes the frame rate during movie shooting, the playback time varies depending on the frame rate after the change as described above, so the user needs to shoot while considering how much the playback time will be. is there.

  Therefore, for a general user who is not used to shooting while changing the frame rate in this way, the playback time is longer or shorter than the user thinks when the playback is performed. There was a thing.

  Therefore, the present invention solves such a problem, and enables a moving image having an appropriate playback time to be recorded when the frame rate of the moving image to be recorded is changed.

  An imaging unit, a recording unit that records the moving image data obtained by the imaging unit on a recording medium, and a playback time corresponding to a predetermined playback speed when the moving image data recorded by the recording unit is played back. A setting unit that is set in response to an instruction, and a time required to record moving image data having a frame rate corresponding to the predetermined reproduction speed of the set reproduction time based on the reproduction time set by the setting unit Is determined as a recording time of moving image data having a frame rate corresponding to the predetermined reproduction speed, and the recorded moving image is changed to the moving image having the predetermined reproduction speed during recording of the moving image data by the recording unit. When instructed, the frame rate of the moving image data recorded by the recording means is changed to a frame rate corresponding to the predetermined reproduction speed. Recording time with the determined, it performs control to automatically record the moving image data of a frame rate corresponding to the predetermined reproducing speed.

  As described above, according to the present invention, when the frame rate of a moving image to be recorded is changed, it is possible to record a moving image with an appropriate reproduction time.

  Hereinafter, examples of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments.

<First Embodiment>
FIG. 1 is a diagram illustrating a configuration of an imaging apparatus 100 to which a recording apparatus as an embodiment of the present invention is applied. FIG. 1 is a block diagram showing the overall configuration of the imaging apparatus 100. In FIG. 1, an imaging unit 101 includes a photographic lens and an imaging element, converts an optical image of a subject into an image signal, performs analog-digital conversion, and outputs the image signal. The imaging unit 101 outputs moving image data in which one frame is 4K (horizontal 3840 pixels × vertical 2180 pixels). Further, as described later, the imaging unit 101 can output moving image data having a frame rate of 240 fps and lower. The image processing unit 102 performs various processes such as a known development process and white balance adjustment on the input image signal and outputs the processed image signal.

  The audio input unit 103 acquires and outputs audio around the imaging apparatus 100. The audio processing unit 104 converts the audio signal input from the audio input unit 103 into a digital signal and outputs the digital signal. The memory 105 temporarily stores an image signal and an audio signal obtained by the image processing unit 102 and the audio processing unit 104 or an encoded image signal and an audio signal.

  At the time of recording, the encoding processing unit 106 reads out the image signal and the audio signal temporarily stored in the memory 105 and performs encoding of the image signal, encoding of the audio signal, etc. Generate data etc. In reproduction, the reproduced moving image data and audio data are decoded and output. At the time of recording, the recording / reproducing unit 107 records the compressed image data, compressed audio data, and other necessary data generated by the encoding processing unit 106 on the recording medium 108. The recording / reproducing unit 107 reads and outputs each data recorded on the recording medium 108 during reproduction. The recording / playback unit 107 manages each data recorded on the recording medium 108 as a file according to a file system such as exFAT. In the present embodiment, moving image data and audio data are recorded according to a known container format such as MP4 or MOV.

  The recording medium 108 is a random access recording medium such as a memory card. The recording medium 108 can be easily discharged and mounted on the imaging apparatus 100 by a mounting / discharging mechanism (not shown). The display control unit 109 displays a moving image obtained by the imaging unit 101 and other information necessary for operation of the imaging device 100 on the display unit 110 during recording. Further, at the time of reproduction, the reproduced moving image or the like is displayed on the display unit 110. The display unit 110 includes a display device such as a liquid crystal display, an organic EL display, and electronic paper.

  The operation unit 112 includes a button, a dial, and the like, and transmits an instruction signal to the control unit 111 according to a user operation. The operation unit 112 includes, for example, a power button, a recording start button, a menu display button, a determination button, a cursor key, a pointing device for designating an arbitrary point on the display unit 110, a touch panel, and the like. The control unit 111 controls each unit of the imaging apparatus 100 based on the instruction signal transmitted from the operation unit 112. The control unit 111 includes, for example, a CPU (MPU), a memory (DRAM, SRAM), and the like for executing various processes (programs). The output unit 113 outputs the moving image data obtained by the imaging unit 101 or the reproduced moving image data to an external recording device or display device. The bus 114 transfers various data, control signals, and the like between the units.

  Next, the recording process of the imaging apparatus 100 will be described. When the user operates the operation unit 112 to turn on the power of the imaging apparatus 100, the control unit 111 puts the imaging apparatus 100 into a recording standby state. In the recording standby state, the imaging unit 101 outputs moving image data, and the image processing unit 102 processes the output moving image data and stores it in the memory 105. The display control unit 109 reads the moving image data from the memory 105 and displays it on the display unit 110. As described above, in the recording standby state, the moving image obtained by the imaging unit 101 is displayed on the display unit 110 as a live view image. The user can set the recording mode of the imaging apparatus 100 in the recording standby state.

  In the present embodiment, the imaging apparatus 100 has a normal recording mode. In the normal recording mode, moving image recording is started in response to a recording start instruction from the user, and moving image recording is stopped in response to a recording stop instruction. In the normal recording mode, the frame rate of the moving image to be recorded is the same from the start of recording to the stop of recording, and cannot be changed by the user. The frame rate of moving image data recorded in the normal recording mode is 60 fps.

  First, normal recording mode processing will be described. In the recording standby state, when the operation unit 112 is operated and there is an instruction to start recording a moving image, the control unit 111 controls each unit to start recording a moving image and audio.

  The imaging unit 101 outputs moving image data of 60 fps. The moving image data from the imaging unit 101 is processed by the image processing unit 102 and temporarily stored in the memory 105. The voice data acquired by the voice input unit 103 is processed by the voice processing unit 104 and stored in the memory 105.

  The encoding processing unit 108 encodes the moving image data and audio data stored in the memory 105 and stores them in the memory 105. The recording / playback unit 107 reads the encoded moving image data and audio data from the memory 105 and records them on the recording medium 108. When recording is performed on the recording medium 108 in this way and the user instructs to stop recording, the control unit 111 controls each unit to stop recording.

  Further, the imaging apparatus 100 has a predetermined recording mode in which the frame rate of a moving image to be recorded can be changed according to a user instruction between the start of recording and the stop of recording. Hereinafter, this predetermined recording mode is referred to as a reproduction double speed change mode.

  In the reproduction double speed change mode, the user can instruct to change the reproduction double speed during reproduction of the recorded moving image by operating the operation unit 112 during recording of the moving image. In this embodiment, when the recorded moving image data is reproduced, the reproduced moving image data is displayed at a predetermined reproduction frame rate. The predetermined playback frame rate is 60 fps. For this reason, the 60 fps moving image that is the same as the playback frame rate is set as a 1 × moving image.

  In the playback double speed switching mode, during recording of a moving image, the user specifies a playback double speed of 1/4 × speed, 1/2 × speed, 1 × speed, 2 × speed, or 4 × speed to record the moving image. Can be instructed to change the playback double speed.

  When the frame rate of the recorded moving image is 240 fps, it is displayed on the display unit 110 as a 1/4 × slow playback (low speed) image. In addition, when the frame rate of the recorded moving image is 15 fps, it is displayed on the display unit 110 as a 4 × fast playback (high speed) image.

  That is, the frame rate corresponding to ¼ times speed is 240 fps, and the frame rate corresponding to 4 times speed is 15 fps. Similarly, the frame rate corresponding to 1/2 speed is 120 fps, and the frame rate corresponding to 1/2 speed is 30 fps.

  Further, in the reproduction double speed change mode, when the user instructs to change the reproduction double speed, the imaging apparatus 100 automatically records moving image data having a frame rate corresponding to the reproduction double speed after the change for a predetermined period. After that, it automatically returns to the recording of the 1 × speed moving image data.

  Furthermore, the user can arbitrarily set the playback time for each playback speed when the playback speed of the moving picture to be recorded is changed when the playback speed of the moving picture to be recorded is changed. The image capturing apparatus 100 records the moving image data having the frame rate corresponding to the changed playback speed based on the playback time set by the user and the frame rate corresponding to each playback speed. Length, length).

  FIG. 5 shows an example of the playback time set for each playback double speed and the recording time length required to record a moving picture at each playback double speed of the set playback time. For example, as shown in FIG. 5, when 5 seconds is set as the playback time of a quadruple-speed movie, in order to record a four-times-speed movie corresponding to five seconds, four seconds of five seconds, 20 seconds. It is necessary to record a 4 × speed moving image. Therefore, the recording time length is 20 seconds. When there is an instruction to change to 4 × speed in the playback double speed change mode, the imaging apparatus 100 records a 15 fps moving image corresponding to 4 × speed for 20 seconds. After that, the video is returned to 60 fps corresponding to 1 × speed.

  In addition, when 16 seconds is set as the recording time of the 1/4 × speed moving image, in order to record the 1/4 time moving image corresponding to the playback time of 16 seconds, 4 seconds, which is 1/4 times 16 seconds, It is necessary to record a 1/4 × moving image. Therefore, the recording time length is 4 seconds. In the reproduction double speed change mode, when there is an instruction to change to 1/4 double speed, the imaging apparatus 100 records a 240 fps moving image corresponding to the 1/4 double speed for 4 seconds. After that, the video is returned to 60 fps corresponding to 1 × speed.

  The user can arbitrarily set the playback time when each moving-speed moving image shown in FIG. 5 is recorded by operating the operation unit 112 in the recording standby state. The control unit 111 stores the reproduction time set by the user in the memory 105, obtains the recording time of each reproduction double speed based on the set reproduction time, and stores it in the memory 105.

  Then, if there is an instruction to change the playback double speed during the recording of the moving image, the control unit 111 records the moving picture having the frame rate corresponding to the post-change playback double speed for the recording time corresponding to the post-change playback double speed. Control each part. When the user does not set the playback time, the control unit 111 sets a predetermined playback time. The control unit 111 calculates a recording time of a moving image corresponding to each reproduction speed as described above and stores it in the memory 105 before receiving a recording start instruction from the user.

  In the playback double speed change mode, only a moving image is recorded, and no sound is recorded. The reason for this is that when playing back a moving image recorded in the playback double speed change mode, the playback double speed may change greatly in the middle, and in that case, the sound cannot be heard normally.

  Next, a moving image recorded in the reproduction double speed change mode will be described. In the reproduction double speed change mode, the control unit 111 controls the imaging unit 101 so as to output moving image data of 240 fps. The imaging unit 101 outputs 240 fps moving image data to the image processing unit 102 in the reproduction double speed change mode. Then, the control unit 111 controls the image processing unit 102 and thins out some frames from the 240 fps moving image data in accordance with the reproduction speed of the recorded moving image, thereby reducing the frame rate of the recorded moving image data. change.

  FIG. 2 is a diagram illustrating a frame of a moving image from the imaging unit 101 and a frame to be recorded and reproduced when a 1 × speed moving image is recorded. The numbers in the figure indicate the frame order (number). As shown in FIG. 2A, the imaging unit 101 outputs a 240 fps moving image. The frame rate of a 1x moving image is 60 fps. Therefore, 60 fps moving image data is obtained by thinning out 3 frames for every 4 frames of the 240 fps moving image in FIG. In other words, one frame of moving image is taken out and recorded every four frames. The recorded moving image is 60 fps as shown in FIG. At the time of reproduction, as shown in FIG. 2 (C), since it is displayed at 60 fps, it is displayed as a 1 × speed moving image.

  FIG. 3 is a diagram illustrating a frame of a moving image from the imaging unit 101 and a frame to be recorded when a change to a 1 / 2-times moving image is instructed. As shown in FIG. 3A, the imaging unit 101 outputs a 240 fps moving image. The frame rate of the 1 / 2-times moving image is 120 fps. Therefore, if there is an instruction to change to 1/2 speed at 301, 120 fps moving image data is obtained by thinning out one frame for every 2 frames of the 240 fps moving image in FIG. The moving image to be recorded is 120 fps as shown in FIG. At the time of reproduction, as shown in FIG. 3 (C), since it is displayed at 60 fps, it is displayed as a half-speed moving image.

  FIG. 4 is a diagram illustrating a frame of a moving image from the imaging unit 101 and a frame to be recorded when a change to a double-speed moving image is instructed. As shown in FIG. 4A, the imaging unit 101 outputs a 240 fps moving image. The frame rate of the double-speed moving image is 30 fps. Therefore, if there is an instruction to change to double speed at the time of 301, 120 fps moving image data is obtained by thinning out 7 frames for every 8 frames of the 240 fps moving image in FIG. In other words, one frame of moving image is taken out and recorded every 8 frames. The moving image to be recorded is 30 fps as shown in FIG. At the time of reproduction, as shown in FIG. 4C, it is displayed at 60 fps, so it is displayed as a double speed moving image.

  Next, processing in the reproduction double speed change mode will be described with reference to the flowchart of FIG. FIG. 6 is a flowchart showing processing in the reproduction double speed change mode. The processing in FIG. 6 is executed by the control unit 111 controlling each unit.

  In the recording standby state, when the operation unit 112 is operated and there is an instruction to start recording a moving image, the process of FIG. 6 is started. When there is a recording instruction, the control unit 111 controls the imaging unit 101 to output 240 fps moving image data as described above. The imaging unit 101 outputs moving image data of 240 fps. The moving image data from the imaging unit 101 is input to the image processing unit 102. The control unit 111 instructs the image processing unit 102 to output a 60 fps moving image in order to record a 1 × moving image after the start of recording until the user instructs to change the reproduction double speed.

  As described with reference to FIG. 2, the image processing unit 102 generates 60 fps moving image data by extracting one frame out of 4 frames of moving image data from the imaging unit 101, and outputs the moving image data to the memory 105. The moving image data stored in the memory 105 is encoded by the encoding processing unit 105 and recorded on the recording medium 108 by the recording / reproducing unit 107 (S601).

  After starting the recording of the moving image data corresponding to the 1 × speed as described above, the control unit 111 determines whether the moving image corresponding to the 1 × speed is being recorded (S602). After the start of recording, the moving image corresponding to the 1 × speed is being recorded until an instruction to change the playback speed is received. When a moving image corresponding to 1 × speed is being recorded, the control unit 111 determines whether or not an instruction to change the reproduction double speed of the moving image being recorded has been received from the operation unit 112 (S603).

  In the present embodiment, during recording in the reproduction double speed change mode, a button for instructing the reproduction double speed after the change is displayed on the display unit 112. The display unit 112 includes, for example, a touch panel, and the user operates the operation unit 112 to operate a button corresponding to the changed playback speed, thereby instructing to change the playback speed of the moving image being recorded. it can.

  When receiving an instruction to change the reproduction double speed, the control unit 111 switches to recording of moving image data corresponding to the reproduction double speed after the change designated by the user. That is, the control unit 111 informs the image processing unit 102 of the frame rate of the moving image corresponding to the reproduction double speed after the change. The image processing unit 102 generates and outputs moving image data at a specified frame rate by thinning out frames of moving image data from the imaging unit 101 based on the frame rate instructed by the control unit 111. The changed frame rate moving image data is encoded by the encoding processing unit 105 and recorded on the recording medium 108 by the recording / reproducing unit 107 (S604). Further, the control unit 111 measures the elapsed time from the start of recording of the moving image corresponding to the reproduction double speed after the change.

  Next, the control unit 111 determines whether a recording stop instruction has been received from the operation unit 112 (S605). If there is an instruction to stop recording, the control unit 111 controls each unit to stop recording the moving image (S606). If there is no instruction to stop recording, the process returns to S602 to continue the processing.

  If there is an instruction to change the reproduction double speed and a moving image corresponding to the reproduction double speed after the change is recorded, it is determined in S602 that the moving image corresponding to the single speed is not being recorded. Therefore, the control unit 111 reads out the recording time corresponding to the playback double speed of the moving image being recorded from the memory 105, and the elapsed time from the start of the moving image recording corresponding to the playback double speed after the change reaches the set recording time. It is determined whether or not it has been done (S607). If the recording time has not been reached, recording continues. When it is determined that the recording time has been reached, the control unit 111 returns the moving image to be recorded to a moving image corresponding to 1 × speed. Therefore, the control unit 111 instructs the image processing unit 102 to output a 1 × speed moving image. The image processing unit 102 generates and outputs 60 fps moving image data from the moving image data from the imaging unit 101 in response to an instruction from the control unit 111. Then, the moving image data of 60 fps is recorded on the recording medium 108 (S608).

  Next, the control unit 111 determines whether a recording stop instruction has been received from the operation unit 112 (S605). If there is an instruction to stop recording, the control unit 111 controls each unit to stop recording the moving image (S606). If there is no instruction to stop recording, the process returns to S602 to continue the processing.

  Next, processing during reproduction will be described. When the user operates the operation unit 112 to instruct the playback mode, the playback mode is set. The control unit 111 controls the recording / playback unit 107 and the display control unit 109 to display a representative image (thumbnail image) of each moving image file recorded on the recording medium 108 on the display unit 110.

  The user operates the operation unit 112 to select a representative image corresponding to a desired moving image file and instruct reproduction. When there is a reproduction instruction, the control unit 111 instructs the recording / reproducing unit 107 to reproduce the designated moving image file. The recording / playback unit 107 reads the designated moving image file from the recording medium 108 and stores it in the memory 105.

  The encoding processing unit 106 reads the encoded moving image data from the memory 105, decodes it, and stores it in the memory 105 again. The display control unit 109 reads each frame of the decoded moving image data from the memory 105 and displays it on the display unit 110. At this time, the display control unit 109 displays the reproduced moving image data at a frame rate of 60 fps.

  Therefore, when the moving image data recorded in the reproduction double speed change mode is reproduced, the moving image data recorded at the frame rate corresponding to the reproduction double speed other than the normal single speed is displayed at each reproduction double speed. In addition, moving image data recorded in the normal recording mode is displayed at 1 × speed.

  As described above, in the present embodiment, in the playback double speed change mode, if the user gives an instruction to change the playback double speed during recording of a moving picture, the moving picture having a frame rate corresponding to the changed playback double speed is recorded. Then, a moving image having a frame rate corresponding to the reproduction double speed after the change is automatically recorded for a recording time determined based on the set reproduction time.

  Therefore, even during recording of a moving image, it is possible to easily switch to and record a moving image having a frame rate corresponding to each reproduction double speed for the set reproduction time.

  In the present embodiment, during recording in the reproduction double speed change mode, a button for instructing the reproduction double speed after the change is displayed on the display unit 112, and the user operates the button corresponding to the reproduction double speed after the change. However, other configurations are possible. For example, information indicating the changed frame rate may be displayed instead of the reproduction double speed, and the user may indicate the changed frame rate. Further, the frame rate information may be displayed together with the reproduction double speed.

  Further, in the reproduction double speed change mode, the structure is changed to any one of the four predetermined reproduction double speeds, but the number of reproduction double speeds may be increased or decreased.

  In the reproduction double speed change mode, the imaging unit 101 outputs a 240 fps moving image, and the image processing unit 102 thins out frames according to the frame rate of the recorded moving image. However, other configurations may be used. . For example, if the image capturing unit 101 can appropriately change the image reading speed from the image sensor, the frame rate of the moving image data output from the image capturing unit 101 may be changed according to each reproduction speed.

  Furthermore, the image processing unit 102 may not be configured to thin out frames, but may be configured to generate moving image data having a frame rate corresponding to each reproduction speed by combining a plurality of previous and subsequent frames.

  In addition, the predetermined playback frame rate that is the frame rate at the time of playback of the recorded moving image data is set to 60 fps, but other frame rates may be used. Also, in the playback double speed change mode, audio is not recorded. However, when a 60 fps moving image corresponding to 1 × speed is recorded, the sound is recorded, and when another moving speed moving image is recorded, the sound is recorded. It is good also as a structure which does not record.

<Second Embodiment>
Next, a second embodiment will be described. Also in the second embodiment, the basic configuration, recording, and playback mode processing of the imaging apparatus 100 are the same as those in the first embodiment. In the first embodiment, the user sets the playback time of a moving image corresponding to each playback speed in the playback speed change mode. In the second embodiment, the user sets the recording time length corresponding to each reproduction double speed in the reproduction double speed change mode.

  The user can arbitrarily set the recording time of each playback speed moving image by operating the operation unit 112 in the recording standby state. When the user sets the recording time, the control unit 111 calculates a playback time when playing back each moving speed double-speed movie corresponding to the recording time input by the user. Then, along with the recording time input by the user, information on the playback time is displayed on the setting screen.

  Thereby, the user can set the recording time while easily confirming the reproduction time of each reproduction double speed moving image corresponding to the input recording time.

  When the user inputs a recording time for each playback speed and instructs setting, the control unit 111 stores information on the set recording time in the memory 105 in association with each playback speed. FIG. 7 shows information on the reproduction double speed and recording time stored in the memory 105.

  Then, if there is an instruction to change the playback double speed during the recording of the moving image, the control unit 111 records the moving picture having the frame rate corresponding to the post-change playback double speed for the recording time corresponding to the post-change playback double speed. Control each part. When the user does not set the recording time, the control unit 111 sets a predetermined recording time. Before receiving a recording start instruction from the user, the control unit 111 sets a recording time of a moving image corresponding to each reproduction double speed as described above, and stores it in the memory 105.

  The subsequent processing is the same as in the first embodiment.
