Description

  The present invention relates to a technique for reproducing and displaying moving image data using a display device.

  Conventionally, in a recording / reproducing apparatus such as a video camera using a tape medium, as a method for reproducing and displaying a recorded scene, a display device such as an LCD or EVF in the video camera main body and a single monitor output terminal are used. In most cases, video images were displayed. As a plurality of screen display methods, there is a method of storing a previously played still image in a memory in a video camera, and reducing the still image to display it as a child screen in the display device. .

  In recent years, video cameras using hard disks, magnetic disks, etc. as storage media have begun to be commercialized. In a video camera or the like using the recording medium, each scene can be stored as a file on the recording medium. Therefore, during playback, each scene can be accessed relatively easily and at high speed. As a video camera playback display method using the recording medium, a still image index is recorded in a file of each scene, the index is displayed in a list, and a file selected from the list is displayed on the video camera body. It is a general function to display only one main moving image on a display device such as LCD (Liquid Crystal Display) and EVF (Electronic View Finder) and a monitor output terminal. This type of apparatus is described in Japanese Patent Application Laid-Open No. H10-228707.

  In addition, the amount of information to be recorded increases as the recorded image quality and recording size increase. However, the capacity of recording media is rapidly increasing due to advances in semiconductor technology. For example, 256- and 512-megabyte products are available for card-type recording media, and a storage capacity of several gigabytes for magneto-optical disks and tens of gigabytes for hard disks can be realized at low cost. For this reason, the recordable time of the recording apparatus is increasing day by day.

First, the recording operation will be described with reference to the block diagram of FIG.
In the image recording operation, light from a subject incident through the lens 101 is converted into an electric signal by the solid state sensor 102. Then, it is sampled by the A / D converter 103 and converted into digital data. The digital data is input to the CPU 130 as a digital video signal. Since the lens 101 has an autofocus function and a zoom function, it moves by driving the motor 104 in accordance with a control command from the CPU 130. A timing signal for extracting data from the solid state sensor 102 is generated by the CPU 130.

  The audio signal obtained from the microphone 109 is amplified by the microphone amplifier 110, sampled by the A / D converter 103, converted into digital data, and input to the CPU 130. The CPU 130 performs basic processing such as color separation, white balance, gamma correction, and aperture correction, and additional processing such as image size, image quality adjustment, and position adjustment set by the operation key 112 of the imaging apparatus 100 by the CPU 130. . Further, the CPU 103 performs image compression processing such as MPEG, MJPEG, JPEG, etc. according to the set compression method and compression parameters, and obtains compressed image data. The audio data is subjected to additional processing such as sound quality adjustment set by the operation key 112 of the imaging apparatus 100, and audio compression data is obtained by the set compression method and compression parameters. The compressed image data and the compressed audio data are sent to the recording / reproduction control circuit 123 as recording data together with the control data. The control data means photographing additional information such as information on the imaging apparatus itself, recording setting information such as images and sounds, and photographing environment information.

  The recording / playback control circuit 123 writes the recording data to the recording medium 125 as a file under the management of the file system during recording. The file system means a structure system composed of management information and file data for managing files. By sharing this file system, recording and reproduction can be performed on different storage media or recording / reproduction devices. The recording data is sent to the external input / output terminal 117 as necessary. Further, it is displayed on the display 114 through the display driver 113 for confirmation.

In the figure, portions D and E show how actual recording data is written.

  In the management area, the file system, disk ID, file (recording scene) attributes, file data actual writing position (sector or track), and the like are recorded. In addition, it is also possible to record the additional shooting information, playlist, etc. in the management area. When the recording start / end switch in the operation key 112 of the imaging device 100 is used to start recording from the recording start, the file is saved in the recording medium 125 as a file with a file name in accordance with the rules of the imaging device 100. This continuously recorded storage file is sequentially recorded as one scene. In the file, in addition to a moving image compressed file such as MPEG, an audio compressed file, additional information data, still image compressed data serving as an index image of moving image data, and the like are also stored.

Next, the reproducing operation will be described with reference to the block diagram of FIG.
When a file selected by the operator is reproduced from the file group recorded on the recording medium 125, the designated file is read from the recording medium 125 under the control of the recording / reproducing control circuit 123. The read data is sent to the CPU 130, where the read data is analyzed and separated, and decomposed into an image data portion, an audio data portion, an information data portion, and the like. If the image data portion is compressed data, the image data portion is expanded and displayed on the display 114 through the display driver 113. If the audio data portion is compressed data, it is decompressed and sent to the speaker 116 through the speaker driver 115. Depending on the content of the information data, processing such as image data, audio data effects, and retouching are performed. Further, it may be displayed on the display 114 as necessary. The image, sound, and information data are also sent to the external input / output terminal 117.

  Further, a reproduction operation and a display operation in this embodiment will be described. FIG. 3 is a diagram showing a reproduction display example of the present embodiment, in which 300a is a parent screen for reproducing and displaying a selected file, and 300b is a child screen displayed and reproduced by a method described later.

FIG. 4 is a diagram for explaining the reproduction operation in the first embodiment of the present invention.
In the figure, (1) shows the playback display of the scene being selectively played back on the time axis in units of fields or frames. (2) displays on the time axis the state of reproduction of the main image reproduced and displayed on the main screen shown at 300a, and the arrows indicate the direction of the time axis. (3) displays the state of sub-screen playback reproduced and displayed on the sub-screen shown in 300b on the time axis, and the arrow indicates the time-axis direction.

  In FIG. 4, the main image reproduction display of the selected file is reproduced on the main screen by reproduction at a normal speed. In parallel with this, the sub-screen display is reproduced at a normal speed for an arbitrary section set before the start of the playback operation or by default setting, that is, in the example of FIG. 4, T1 time from FA in the scene to FE. Display the video to be played.

  In the sub-screen playback, when the scene end point FE is reached, playback is repeated so that playback from the FA starts again. This repetition continues until the end of the main image reproduction. Alternatively, the number of repetitions may be determined by setting, or one child screen reproduction may be ended. In this case, as a method of ending the reproduction of the child screen, it is conceivable to freeze the child screen with a still image display or to eliminate the child screen itself.

  FIG. 5 is a flowchart showing the operation of the imaging apparatus 100 according to the present embodiment. Scene reproduction is started, and initial settings of circuits, software, etc. relating to the reproduction operation are made in S401.

  In S403, the media data 1 is read from the recording medium to display the main screen of the scene. In S404, it is determined whether or not the scene is finished. If there is no read data, the reproduction process ends. Otherwise, the process proceeds to S405. In S405, the media data 2 for reproducing the small screen is read. In S406, it is determined whether or not the sub-screen playback is finished. If there is no read data, the process proceeds to S407, and if not, the process proceeds to S408. In S407, the read data position for reproducing the small screen is reset to the initial value, and the process proceeds to S408. In step S408, the read media data 1 is subjected to decoding processing and image processing so as to display an image, and the image is displayed as a parent screen. In step S409, the read media data 2 is subjected to decoding processing and image processing so as to display an image as a sub-screen. For the resizing of the child screen image and the image synthesis of the parent screen and the child screen, a method of developing in an image buffer by processing by the CPU or a method using an image processing circuit or the like can be applied.

  In S410, it is determined whether the operation key is stopped or the end of the scene is detected. If it is determined to end, a reproduction end process is performed and this process ends. Otherwise, return to S403 and continue the process. As the timing of the repetitive processing from S403 to S410, either a synchronous timing such as a field or a frame or an asynchronous timing after data reading from the recording medium reaches a predetermined buffer amount can be applied. In addition, the steps of reading parent image data, reading child image data, decoding and reproducing parent image, and decoding and reproducing child image are read parent image data, decoding and reproducing parent image, reading child image data, It is also possible to use a procedure such as a decoding reproduction process of a child image.

  In the above example, FIG. 3 is used as a reproduction display example, a main body display such as an LCD or EVF, an external display via a main body external input terminal, or a terminal on a network via a main body external input terminal. An example of display as a parent / child screen on a display device or a display device has been shown, but this screen is a main body display such as an LCD or EVF, and a sub screen is an external display, terminal, display device, etc. via a main body external input terminal It is also possible to apply separate display. Alternatively, the sub-screen can be applied to a main body display such as an LCD or EVF, and the main screen can be separately displayed on an external display, terminal, display device or the like via a main body external input terminal. At this time, the child screen may be displayed without being resized.

  As described above, according to the present embodiment, while reproducing one file from the beginning, any portion of the same file (for example, a scene at the end portion) is simultaneously reproduced and displayed in a composite manner. An arbitrary portion of the moving image playback image can be sequentially confirmed. As a result, for example, the scene contents can be easily grasped so that the current reproduction scene can be visually grasped so that a desired scene can be retrieved more easily. In particular, consumer video cameras and the like have an effect of providing high-value-added functions that have not existed before.

  In FIG. 6, the main image reproduction display of the selected file is reproduced on the main screen by reproduction at a normal speed. In parallel with this, the sub-screen display is in the same range as the scene being selected and played back at an arbitrary playback speed set before the start of the playback operation or at the default setting (for example, faster than the playback speed of the parent screen). Play video from the beginning of the scene to the end of the scene.

  In the sub-screen playback, when the end of the scene is reached, the playback is repeated so that the playback starts from the first scene again. This repetition continues until the end of the main image reproduction. Alternatively, the number of repetitions may be determined by setting, or one child screen reproduction may be ended. In this case, as a method of ending the reproduction of the child screen, it is conceivable to freeze the child screen with a still image display or to eliminate the child screen itself.

In particular, consumer video cameras and the like have an effect of providing high-value-added functions that have not existed before.

<Third Embodiment>
Next, a third embodiment of the present invention will be described.
Since the imaging apparatus according to the present embodiment has the same configuration as that shown in FIG. FIG. 7 is a diagram showing a screen display example according to the present embodiment. In FIG. 7, reference numeral 501a denotes a parent screen that reproduces and displays the selected scene, 502b denotes a child screen that reproduces and displays the previous scene, and 502c denotes a rear screen. This is a sub-screen that plays back and displays a scene. In FIG. 2B, reference numeral 502a denotes a parent screen for reproducing and displaying the selected scene, 502b denotes a child screen for reproducing and displaying the previous scene, and 502c denotes a child screen for reproducing and displaying the selected scene used in the first and second embodiments. A screen 502d is a sub-screen that reproduces and displays the subsequent scene.

In the reproduction display operation of the present embodiment, the selected scene is reproduced and displayed on the parent screen, and at the same time, the moving image is reproduced and displayed using the scene before the selected scene as a child screen. At the same time, a moving image is reproduced and displayed using the scene after the selected scene as a sub-screen. The preceding and following scenes can be set as scenes with a predetermined interval set by the user setting immediately before and after the selected scene. In addition, before and after on the time axis (time stamp, recording date and time), before and after the scenes sorted, before and after the scenes classified into categories can be considered. Further, it is also conceivable to display one or more playback display scenes before and after each.
Further, as in the display example of (2) in the figure, the sub-screen moving image reproduction display in the selected scene used in the first and second embodiments may be performed. The sub-screen playback method for the preceding and following scenes uses the sub-screen video playback display method used in the first and second embodiments.

  FIG. 8 is a flowchart showing the operation of the imaging apparatus 100 according to the present embodiment. Playback of the selected scene 1 is started, and initial settings such as circuits and software relating to the playback operation are made in S601. In S602, various settings relating to this operation are performed. Various settings are items that can be selected and set by the user using the operation keys and operation panel. ・ Number of displayed sub-screens before and after, ・ Interval between each sub-screen from the selected scene ・ End operation method of each sub-screen, ・ Each sub-screen The size of the screen, the spatial resolution of each sub-screen, the temporal resolution of each sub-screen, the display position of each sub-screen, etc. If there is no user setting, the default value is set. In step S603, the media data 1 is read from the recording medium so as to display the main screen of the scene. In step S604, it is determined whether the scene is finished. If there is no read data, the reproduction process ends. Otherwise, the process proceeds to S605.

  In S605, the media data 2 for reproducing the sub-screen of the selected scene 1, the media data 3 for reproducing the previous-scene sub-screen, and the media data 4 for reproducing the sub-scene sub-screen are read. In step S606, it is determined whether or not each sub-screen playback is finished. If there is no read data for any one of the sub-screens, the process proceeds to S607, and if not, the process proceeds to S608. In S607, the read data position of the small-screen reproduction in which there is no read data is reset to the initial value, and the process proceeds to S608.

  In step S608, the read media data 1 is subjected to decoding processing and image processing so as to display an image as a parent screen. In step S609, the read media data 2, 3, and 4 are subjected to decoding processing and image processing so as to be displayed as images, and images are displayed as sub-screens. For the resizing of each sub-screen image and the image synthesis of the main screen and each sub-screen, a technique of developing in an image buffer by processing by the CPU or a technique using an image processing circuit or the like can be applied. In S610, it is determined whether the previous scene or the subsequent scene is designated by image designation such as an operation key, an operation panel, or a touch panel on the display screen.

  If it is designated, the process proceeds to S611, and if it is not designated, the process proceeds to S612. In S611 when designated, the scene before or after the designated scene 1 is replaced with the scene 1 currently selected and reproduced. Accordingly, the preceding and succeeding scenes are determined based on the replaced scene. In step S612, it is determined whether the operation key is stopped or the end of the scene is detected. If it is determined to end, the reproduction end process is performed and the present process ends. Otherwise, the process returns to S603 and continues. The repetitive processing timing from S603 to S612 uses the method described in the first embodiment.

  In the above description, FIG. 7 is used as a reproduction display example, a main body display such as an LCD or EVF, an external display via a main body external input terminal, or a terminal on the network via a main body external input terminal. An example of display as a parent / child screen on a display device or a display device has been shown, but this screen is a main body display such as an LCD or EVF, and a sub screen is an external display, terminal, display device, etc. via a main body external input terminal It is also possible to apply separate display. Alternatively, the sub-screen can be applied to a main body display such as an LCD or EVF, and the main screen can be separately displayed on an external display, terminal, display device or the like via a main body external input terminal. At this time, the child screen may be displayed without being resized.

  As described above, according to the present embodiment, while reproducing one file, the previous and subsequent files (which may be either the front or the rear) are simultaneously reproduced and combined to display a shooting scene. It becomes possible to check the moving image playback images of the scenes before and after. Therefore, the relationship between the scenes before and after the current playback scene in the storage medium can be visually grasped, the relation between the respective scenes can be easily grasped, and a desired scene can be retrieved more easily. Further, the search operation is improved by selecting the preceding and following scenes and replacing the currently selected scene.

When a scene different from the parent screen is designated as the child screen, the scene is set. If there is no user setting, the default value is set. In step S803, the media data 1 is read from the recording medium to display the main screen of the scene. In step S804, it is determined whether the scene is ended. If there is no read data, the reproduction process ends. Otherwise, the process proceeds to S805.

  In S805, the media data 2 for reproducing the small screen is read. In S806, it is determined whether or not the sub-screen playback is finished. If there is no read data, the process proceeds to S507, and if not, the process proceeds to S808. In S807, the readout data position for small-screen playback is reset to the initial value, and the process proceeds to S808. In step S808, the read media data 1 is subjected to decoding processing and image processing so as to display an image as a parent screen.

  In step S809, a position at which the ratio of the current playback scene time to the total scene length and the ratio of the movement distance of the child screen to the maximum movement distance of the child screen substantially coincide is calculated as the child screen display position. In step S810, the read media data 2 is subjected to decoding processing and image processing in a form for displaying an image, and an image is displayed at the calculated display position as a sub-screen. For the resizing of the child screen image and the image synthesis of the parent screen and the child screen, a method of developing in an image buffer by processing by the CPU or a method using an image processing circuit or the like can be applied. In step S811, it is determined whether the operation key is stopped or the end of the scene is detected. If it is determined to end, a reproduction end process is performed and this process ends.
