  A video processing apparatus that reproduces video blurring that is related to recorded video data after correction by a reproduction anti-vibration function is conceivable. This video processing device can reproduce unblurred video when the recorded video data is played back on the main body, but when the recorded video data is output to an external device, the uncorrected video is reproduced. Will be output. For example, when the video processing device copies the video recorded in the built-in medium to an auxiliary storage device such as an SD card or a USB card, the uncorrected video is copied. Therefore, when another video processing apparatus reproduces the video data using the auxiliary storage device in which the video is copied, the video with blurring is reproduced.

  Further, for example, when the video processing device communicates with another video processing device and transmits the video recorded in the built-in medium to the other video processing device, an uncorrected video is transmitted. Therefore, the other video processing device reproduces the video with blurring.

FIG. 2 is a diagram showing a configuration example of the digital video camera shown in FIG.
The photographing lens 103 is a lens group including a zoom lens and a focus lens. The shutter 101 is a shutter having an aperture function. The imaging unit 22 is an imaging device configured by a CCD, a CMOS device, or the like that converts subject light into an electrical signal. The A / D converter 23 converts the analog signal output from the imaging unit 22 into a digital signal. The barrier 102 covers an imaging system including the photographing lens 103 of the digital video camera 100. This prevents the imaging system including the taking lens 103, the shutter 101, and the imaging unit 22 from being soiled or damaged.

  The image processing unit 24 performs resize processing and color conversion processing such as predetermined pixel interpolation and reduction on the data from the A / D converter 23 or the data from the memory control unit 15. The image processing unit 24 performs predetermined calculation processing using the captured image data. The system control unit 50 performs exposure control and focus detection based on the calculation result obtained by the image processing unit 24. Thereby, AF (autofocus) processing, AE (automatic exposure) processing, and EF (flash pre-emission) processing of the TTL (through-the-lens) method are performed.

  The image processing unit 24 performs predetermined arithmetic processing using the captured image data, and performs TTL AWB (auto white balance) processing based on the obtained arithmetic result. Further, the image processing unit 24 further performs predetermined calculation processing using the captured image data, and also performs electronic enlargement type image stabilization processing based on the obtained calculation result.

  Output data from the A / D converter 23 is directly written into the memory 32 via the image processing unit 24 and the memory control unit 15 or via the memory control unit 15. The memory 32 stores video data obtained by the imaging unit 22 and converted into digital data by the A / D converter 23 and data to be displayed on the display units 28 and 29. The memory 32 has a storage capacity sufficient to store a predetermined number of still images, a moving image and sound for a predetermined time. The memory 32 also serves as an image display memory (video memory).

  The D / A converter 13 converts the data recorded in the memory 32 into an analog signal and supplies it to the display units 28 and 29. As a result, the video data recorded in the memory 32 is displayed on the display unit 28 via the D / A converter 13. The display units 28 and 29 perform display according to the analog signal from the D / A converter 13 on a display such as an LCD. A digital signal once A / D converted by the A / D converter 23 and stored in the memory 32 is converted into an analog signal by the D / A converter 13 and sequentially transferred to and displayed on the display units 28 and 29 to display an electronic view. It functions as a viewfinder and can display through images.

  The nonvolatile memory 56 is an electrically erasable / recordable memory. As the nonvolatile memory 56, for example, an EEPROM or the like is used. The nonvolatile memory 56 stores constants, programs, and the like for operating the system control unit 50. This program is a program for executing various flowcharts described later in the present embodiment.

  The system control unit 50 controls the entire digital video camera 100. The system control unit 50 implements each process of the present embodiment to be described later by executing a program recorded in the nonvolatile memory 56. Here, it is assumed that the digital video camera 100 has both a reproduction anti-vibration function (first correction function) based on a metadata method and a reproduction anti-vibration function (second correction function) based on a vector detection method. When executing the image stabilization based on the metadata method, the system control unit 50 records the blur information indicating the camera shake detected by the sensor at the time of image capturing in the memory 32 together with the image data as metadata, and reproduces the image. Sometimes, blur information is corrected using blur information. When executing the image stabilization based on the vector detection method, the system control unit 50 detects (generates) blur information (motion vector) indicating the blur of the video from the video data recorded in the memory 32, and generates the motion vector. In response, control is performed to select a partial area of the video and display it in an enlarged manner.

  In the system memory 52, constants and variables for operating the system control unit 50, programs read from the nonvolatile memory 56, and the like are expanded. The system memory 52 is, for example, a RAM. The system control unit also performs display control by controlling the memory 32, the D / A converter 13, the display units 28 and 29, and the like. The system timer 53 is a time measuring unit that measures the time used for various controls and the time of a built-in clock. The mode switch 60, the trigger button 61, and the operation unit 70 are operation means for inputting various operation instructions to the system control unit 50.

  The mode changeover switch 60 switches the shooting mode when the operation mode of the system control unit 50 is the moving image shooting mode or the still image shooting mode. The switching destination shooting mode includes, for example, an auto shooting mode, an auto scene discrimination mode, a manual mode, various scene modes for shooting settings for each shooting scene, a program AE mode, and a custom mode. The user may switch the large frame shooting mode once with the mode switch 60 and then switch to a more detailed shooting mode using another operation member.

  By operating the trigger button 61, the system control unit 50 starts a series of imaging processing operations from reading a signal from the imaging unit 22 to writing image data on the recording medium 200. Each operation member of the operation unit 70 is appropriately assigned a function for each scene by selecting and operating various function icons displayed on the display units 28 and 29, and functions as various function buttons.

  The function buttons include an end button, a return button, an image advance button, a jump button, a narrowing button, an attribute change button, and the like. For example, when a menu button is pressed, various settable menu screens are displayed on the display units 28 and 29. The digital video camera 100 includes a touch panel that can detect contact with the display unit 28 as a member included in the operation unit 70.

  The touch panel and the display unit 28 can be configured integrally. For example, the touch panel is configured such that the light transmittance does not hinder the display of the display unit 28, and is attached to the upper layer of the display surface of the display unit 28. Then, the input coordinates on the touch panel are associated with the display coordinates on the display unit 28. Thereby, it is possible to configure a GUI as if the user can directly operate the screen displayed on the display unit 28.

  The system control unit 50 can detect the following operations on the touch panel. Touching the touch panel with a finger or a pen (hereinafter referred to as touchdown). The touch panel is touched with a finger or a pen (hereinafter referred to as touch-on). The touch panel is moved while being touched with a finger or a pen (hereinafter referred to as a move). The finger or pen that was touching the touch panel is released (hereinafter referred to as touch-up). A state where nothing is touched on the touch panel (hereinafter referred to as touch-off). These operations and the position coordinates of the finger or pen touching the touch panel are notified to the system control unit 50 through the internal bus, and the system control unit 50 performs any operation on the touch panel based on the notified information. It is determined whether or not.

  Regarding the move, the moving direction of the finger or pen moving on the touch panel can also be determined for each vertical component / horizontal component on the touch panel based on the change in position coordinates. When touch-up is performed on the touch panel through a certain move from touchdown, the system control unit 50 determines that a stroke has been drawn.

  The operation of drawing a stroke quickly is called a flick. A flick is an operation of quickly moving a certain distance while touching a finger on the touch panel and releasing the touch as it is, in other words, an operation of quickly tracing a finger on the touch panel. If it is detected that the moving is performed at a predetermined speed or more over a predetermined distance, and a touch-up is detected as it is, it can be determined that a flick has been performed. In addition, when it is detected that the moving is performed at a predetermined distance or more at a speed lower than the predetermined speed, the system control unit 50 determines that the drag has been performed. As the touch panel, any of various types of touch panels such as a resistive film type, a capacitance type, a surface acoustic wave type, an infrared type, an electromagnetic induction type, an image recognition type, and a photo sensor type may be used. Good.

Further, the power control unit 80 controls the DC-DC converter based on the detection result and the instruction from the system control unit 50, and supplies a necessary voltage to each unit including the recording medium 200 for a necessary period.

  The power supply unit 30 includes a primary battery such as an alkaline battery or a lithium battery, a secondary battery such as a NiCd battery, a NiMH battery, or a Li battery, an AC adapter, or the like. The recording medium I / F 18 is an interface with the recording medium 200. The recording medium 200 is a recording medium that records a captured image. In this example, the recording medium 200 is an auxiliary storage device such as an SD card or a USB card, and corresponds to an external device of the digital video camera 100. The data communication I / F 19 is an interface with the data communication unit 33 such as USB or Wi-Fi.

The button on the upper right of the selection screen shown in FIG. 3B is a button for returning to FIG. 3A which is the previous screen. Note that the description when the delete button is operated is omitted.

  FIG. 3C shows a selection screen for selecting whether to copy all scenes or select individual scenes. When the user operates the selection button, the display state is changed to that shown in FIG. When the user operates all scene buttons, the display state changes to that shown in FIG. When the user operates the return button on the upper right, the screen transitions to FIG. 3B, which is the previous screen.

  FIG. 3D shows an index display screen for individually selecting copy targets. As indicated by broken lines, when a and c are selected as copy targets and the execute button is operated, the display state changes to FIG. When the user operates the return button in the upper right of FIG. 3D, the screen transitions to FIG. 3C, which is the previous screen.

  FIG. 3E shows a selection screen for selecting whether to copy after performing reproduction anti-vibration or to perform normal copying without performing reproduction anti-vibration. It takes real time for recorded video to perform playback image stabilization. Therefore, the digital video camera 100 displays the selection screen shown in FIG. 3E so as not to cause the stress of the user who does not need the reproduction image stabilization. When the user operates the reproduction anti-vibration button or the normal button, the state transitions to the display state of FIG. When the user operates the return button on the upper right in FIG. 3E, the screen transitions to FIG. 3D, which is the previous screen.

  FIG. 3F is a final confirmation screen for the copy operation. When the user operates the “Yes” button, the display state of FIG. When the user operates the “No” button, the screen transitions to the previous screen in FIG.

  FIG. 3G is a copy execution screen. In order to indicate the degree of progress, the digital video camera 100 displays a progress bar. When the copy process ends, the display state transitions to the display state of FIG. When the user operates the cancel button, the screen transitions to FIG.

  FIG. 3H is a confirmation screen for the completion of the copy process. When the user operates the OK button, the screen transitions to FIG. 3A, which is the first screen. Here, in FIG. 3G, a progress bar is displayed to indicate the degree of progress, but the user may recognize that copying is being performed using a display member such as an LED. Then, when the user turns off the power of the display unit such as the LCD panel, the power saving effect may be prioritized.

FIG. 4 is a flowchart for explaining an example of operation processing when a copy operation is executed.
The system control unit 50 starts a recording video copy sequence (step S401). Specifically, the system control unit 50 functions as an output detection unit that detects the start of output of video data to the recording medium 200. Subsequently, the system control unit 50 determines whether the copy method selected by the user is a copy method after performing reproduction anti-vibration or a normal copy method without performing reproduction anti-vibration (step). S402). If the copy method selected by the user is a normal copy method that does not perform reproduction image stabilization, the process proceeds to step S406. If the copy method selected by the user is a method of copying after performing reproduction anti-vibration, the process proceeds to step S403.

  In step S403, the system control unit 50 performs recording video decoding processing. Subsequently, the system control unit 50 performs reproduction image stabilization processing on the decoded video (step S404). Specifically, the system control unit 50 functions as a shake acquisition unit that acquires video shake information. The system control unit 50 corrects image blur based on the acquired blur information. Subsequently, the system control unit 50 re-encodes the video subjected to the reproduction anti-vibration processing, and temporarily stores it in the built-in memory (step S405). Then, the system control unit 50 starts copy processing to the recording medium 200 using the recorded video temporarily stored in the built-in memory (step S406). In other words, the system control unit 50 controls the output of the video data whose video blurring has been corrected to the recording medium 200.

  In step S405, the video is temporarily stored, but when the same operation is re-executed, in order to avoid taking real time again by performing processing such as decoding, image stabilization, and encoding again, You may record this. However, for this purpose, a built-in memory having a sufficient storage capacity is required. In this case, on the index display screen in the playback mode of FIG. 3A, a display that can be used to determine whether or not the conversion has been performed is used so that the user can easily understand the specification. The system control unit 50 may display an end time prediction at the time of copying on the index display screen.

  With the above processing, when copying a video from the memory 32 to the removable recording medium 200, control is performed so that the video is converted into a video that has undergone blurring correction processing and then copied. Even in the case of reproduction, it is possible to reproduce an image whose camera shake is corrected.

(Example 2)
The video processing apparatus according to the second embodiment transfers video data from another built-in memory 32 to another video processing apparatus using Wi-Fi.

FIG. 5 is a diagram for explaining video data output processing by the video processing apparatus according to the second embodiment.
FIG. 5A is a Wi-Fi menu screen displayed by the digital video camera 100 in the playback mode. In this state, when the user operates the file transfer button, the display state shown in FIG. The Wi-Fi setting button is for setting a transfer destination device, and the description when the button is operated is omitted.

  FIG. 5B is a selection screen for selecting whether a transfer target is an untransferred file or all files. When the user operates an untransferred file button or all file buttons, the display state is changed to the display state of FIG. The upper right button is a button for returning to FIG. 5B, which is the previous screen.

  FIG. 5C is a selection screen for selecting whether to perform transfer after performing image stabilization or to perform normal transfer without performing image stabilization. When the user operates the reproduction anti-vibration button or the normal button, the display state transitions to the display state of FIG. When the user operates the upper right return button, the screen transitions to FIG. 5B, which is the previous screen.

  FIG. 5D is a final confirmation screen for the copy operation. When the user operates the “Yes” button, the display state of FIG. When the user operates the “No” button, the screen transitions to the previous screen in FIG.

  FIG. 5E is a transfer execution screen. The digital video camera 100 displays a progress bar to indicate the degree of progress. When the transfer process ends, the display state transitions to FIG. When the user operates the cancel button, the screen transitions to FIG. 5A, which is the first screen. FIG. 5F is a confirmation screen for the completion of the transfer process. When the user operates the OK button, the screen transitions to FIG. 5A, which is the first screen.

  In FIG. 5C, when the user selects the reproduction anti-vibration button, the user communicates with another video processing apparatus, and it is found that this video processing apparatus has a reproduction anti-vibration function. It is also possible to display a warning for confirming whether to perform transfer with reproduction anti-vibration. Further, without performing warning display, it is possible to automatically switch to normal transfer without reproduction anti-vibration on the assumption that the reproduction anti-vibration function of another video processing apparatus is used.

  The internal processing of the main body when executing the transfer operation is equivalent to the processing described with reference to FIG. In other words, when the system control unit 50 determines to perform reproduction stabilization and transfer processing, the recorded image is transferred to another video processing apparatus after performing reproduction stabilization processing on the video data.

(Example 3)
FIG. 6 is a flowchart for explaining video data output processing by the video processing apparatus according to the third embodiment.

  In the third embodiment, the digital video camera 100 determines whether to transfer after performing image stabilization based on the result of communication with another video processing apparatus, or to perform normal transfer without performing image stabilization. Switch automatically.

  The system control unit 50 detects an instruction to start communication with another video processing apparatus (step S601). That is, the system control unit 50 detects the start of output of video data to an external device. Subsequently, the system control unit 50 determines whether or not the communication destination video processing apparatus has a reproduction image stabilization function (step S602). Specifically, the system control unit 50 functions as a correction function acquisition unit that acquires correction function information related to a video blur correction function of a communication destination video processing apparatus. In this example, the system control unit 50 acquires the correction function information from another video processing apparatus of the communication destination, but may acquire the correction function information stored in advance in a predetermined storage unit. Based on the correction function information, the system control unit 50 determines whether or not the communication destination video processing apparatus has a reproduction image stabilization function. If the communication destination video processing apparatus does not have a playback image stabilization function, the process advances to step S605. Then, the system control unit 50 transfers the video subjected to reproduction anti-vibration using both the vector detection method and the metadata method to the communication destination video processing device (step S605).

  If the communication destination video processing apparatus does not have a playback image stabilization function, the process advances to step S603. Then, the system control unit 50 determines whether or not the blur correction function of the communication destination video processing device corresponds to the reproduction detection function of the vector detection method (step S603). The fact that the blur correction function corresponds to the vector detection type image stabilization function means that the communication destination video processing apparatus can execute the vector detection type image stabilization function. If the blur correction function does not correspond to the vector detection type reproduction image stabilization function, the process proceeds to step S605. If the blur correction function corresponds to the vector detection type image stabilization function, the process advances to step S604. Then, the system control unit 50 determines whether or not the blur correction function of the communication destination video processing apparatus corresponds to the metadata-based reproduction image stabilization function (step S604).

  If the blur correction function does not correspond to the metadata type image stabilization function, the process advances to step S605. If the blur correction function corresponds to the metadata-based reproduction image stabilization function, the process proceeds to step S606. Then, the system control unit 50 transfers the video to the communication destination video processing device without causing the playback anti-vibration function of the camera body to function, that is, without correcting the blur. That is, the digital video camera 100 switches whether or not to transmit the video data in which the blurring of the video is corrected to the other video processing device based on the correction function information of the communication destination video processing device.

  If the determination process in step S604 is No, the main body applies the metadata type reproduction image stabilization to transfer the video data, and the vector detection type reproduction image stabilization is left to the communication destination image processing apparatus. Good. In particular, when there is a parameter that can determine the performance of the vector detection method in communication with the video processing apparatus of the communication destination, the system control unit 50 prevents the reproduction of the vector detection method on the main body based on the superiority of the data content. You may make it determine whether to shake. As a result, a more accurate reproduction anti-vibration effect can be obtained.

  By the above processing, when data is transferred from the memory 32 to another video processing device, it is controlled so as to be converted into a video subjected to blur correction processing and transferred to be reproduced on the other video processing device. Even in such a case, it is possible to reproduce a video whose blur has been corrected. In addition, by changing whether or not playback anti-vibration processing is performed on the main unit according to the playback anti-vibration function provided in other video processing devices, transfer time can be shortened and more accurate correction effects can be obtained. Is also possible.

  In addition, when the digital video camera 100 performs the main body playback, the processing from step S403 to step S405 in FIG. 4 is executed in parallel with the playback of the recorded video on the display unit, and the video data is recorded. You may make it keep. As a result, the processing time can be shortened at the time of subsequent copying and transfer execution.
