Description

  The present invention relates to an imaging device and a playback device having a scenario mode for shooting an event configured based on a scenario of various themes according to a scenario using an imaging device such as a video camera or a playback device.

  In recent years, with the widespread use of digital cameras and video cameras, opportunities to see landscapes where many users are shooting their own images have increased in places such as children's athletic meet and friends' weddings.

  However, there is a need to shoot movies with high storyline and high degree of perfection in accordance with the flow of each theme such as “athletic meet” and “wedding” in shooting in such a place.

  As a means to meet such needs, event information configured based on the flow of each theme is given to an imaging device such as a digital camera or a digital video camera, and video is taken according to the information of the event. An imaging apparatus having a “scenario mode” capable of performing excellent and high-quality video shooting is known.

  For example, events in the wedding theme flow include the entrance of the bride and groom, the toast, the entrance of the cake, the exit of the bride and groom, etc., and these events are recorded as event information in the imaging device.

  This allows the user to shoot events that are progressing based on the flow of each theme according to the event information, so that the shooting of a video with a high degree of storylines and completeness can be performed without missing the events that should be shot with that theme. It can be carried out.

  By the way, in such an imaging apparatus, a photographer designates a theme and event information in advance before performing a photographing operation. When shooting is performed in a state where event information in any theme is specified, the specified theme and event information are recorded in association with the shot video.

  Therefore, if the photographer forgets to specify the theme and event information before performing the shooting operation, the event information will not be added to the video, and the video will not be excellent in story and high in completeness. End up. In order to avoid this, it is necessary to add an event item to the video that has been shot without adding the theme or event item after shooting.

  In Patent Document 1, an event is identified for a captured video using video analysis, a scenario corresponding to the event of the identification result is selected, and editing processing is performed based on the editing content associated with the selected scenario. Video editing devices have been proposed.

The present invention is described below. The form is not limited.

<First Embodiment>
FIG. 1 is a block diagram showing a schematic configuration as an example of an imaging apparatus 100 according to an embodiment of the present invention. When no event item is added to the video obtained by shooting, the imaging apparatus 100 extracts the event item from the video analysis and the shooting situation of the recorded event video, and selects event item candidates to be added. Has a function to select.

  Here, the details of the configuration of the theme information will be described with reference to FIG. FIG. 2 is a diagram illustrating theme information management data in the scenario mode of the imaging apparatus 100 according to the first embodiment.

  Themes represent general concepts such as “athletic meet”, “wedding”, and “travel”, and events that determine the main events that make up the theme name 201 and the entire theme as theme information for each theme. Item 202 is associated. For example, event items in the theme information of “wedding” include “bride and groom entrance”, “toast”, “cake sword”, and the like.

  A light beam representing a subject image is collected by the imaging lens 101 and is incident on an imaging element 102 such as a CCD image sensor or a CMOS image sensor. The image sensor 102 outputs an electrical signal corresponding to the intensity of the incident light beam in units of pixels. This electrical signal is a video signal. The video signal output from the image sensor 102 is subjected to analog signal processing such as correlated double sampling (CDS) in the analog signal processing unit 103.

  The video signal output from the analog signal processing unit 103 is converted into a digital data format by the A / D conversion unit 104, and a digitized image is generated. The digitized image is input to the control unit 105 and the image processing unit 106 as an image to be processed.

  The control unit 105 is a CPU (Central Processing Unit), a microcontroller, or the like, and centrally controls the operation of the imaging apparatus 100.

  In the present embodiment, the imaging apparatus 100 has a plurality of predefined theme information, and each theme information is associated with a plurality of event items based on the theme name and the theme.

  In the scenario mode of the present embodiment, an event item associated with the theme information is added to the video shot using the event adding unit 110 and recorded on the recording medium 108 or the like. The theme information described here is recorded in, for example, a ROM included in the control unit 105.

  The event item adding unit 110 adds an event item associated with the theme information to the video composed of the processing target images input to the control unit 105. As an event item adding method by the event item adding unit 110, an event item that the user wants to add is selected by operating the operation unit 109, or an event item selected by an event item selecting unit described later is manually or There is a method of automatically selecting and adding.

  As a procedure for adding the event item selected by the user, for example, a case of adding the event item “Bride and Groom Entrance” in the theme information “wedding” will be described with reference to FIG. FIG. 3 is a diagram showing a theme information selection screen and an event item selection screen when adding event items.

  The user operates the operation unit 109 to display the theme selection screen 301 on the display unit 107. On the theme selection screen, for example, a plurality of theme information 302 recorded in a ROM or the like included in the control unit 105 is displayed. From the theme information 302, the operation unit 109 is operated to select “wedding” as the target theme information. After selecting the target theme, the operation unit 109 is operated to display the event item selection screen 303 on the display unit 107. On the event item selection screen, an event item 304 associated with the selected theme information “wedding” is displayed. From this event item information 304, the desired event item information “Bride and groom entrance” is selected.

  Thereby, event item information associated with the theme information can be added to the photographed video.

  Here, the details of the configuration and operation when the event item selected by the event item selection unit 113 is added manually or automatically will be described with reference to FIGS.

  FIG. 4 is a diagram showing a data structure of event item information in the first embodiment. The event item information is recorded in, for example, a ROM included in the control unit 105. FIG. 4 shows, for example, data indicating event items related to “wedding” in the theme information shown in FIG. For example, as shown in FIG. 4, the event item information includes “registered subject information” and “temporal relationship information” indicating the shooting order.

  FIG. 5 is a diagram showing management data of event videos that have already been taken in the scenario mode of the first embodiment. In this embodiment, the event video management data is recorded on the recording medium 108 in a state in which the event item information described above is associated. As shown in FIG. 5, the event video management data in this embodiment includes “video ID”, “theme name”, “event item”, “shooting location information”, and “shooting date information”.

  FIG. 6 is an explanatory diagram of processing of the event item selection unit 113 according to the first embodiment. The first event item extraction unit 111 extracts a candidate event item when the event item addition unit 110 does not add an event item to the video composed of the processing target images input to the control unit 105. . At this time, the first event item extraction unit 111 extracts event item candidates using the image analysis result of the image processing unit 106. The processing of the first event item extraction unit 111 will be specifically described later with reference to FIG.

  The image analysis in the image processing unit 106 includes subject identification for identifying a subject in a captured video. In the present embodiment, as shown in FIG. 4, subject information is associated with event items associated with theme information (hereinafter referred to as registered subject information). The subject information is a face image or subject name of an assumed subject that appears in an event to be photographed. This registered subject information is used for comparison with the image analysis result of the image processing unit 106.

  Further, the image processing unit 106 of the imaging apparatus according to the present embodiment has a subject identification mechanism (not shown) that identifies a subject appearing in the image with respect to the processing target image.

  A subject identification method using the face authentication function in the subject identification mechanism of the present embodiment will be described. In the face authentication function, first, a face area is detected from a captured video, and feature data different for each individual is extracted for the detected face area. Next, by comparing the extracted feature data with previously registered feature data, it is identified whether or not the detected face area is a registered person. In the imaging apparatus 100 according to the present embodiment, feature data related to a subject to be identified is registered. Feature data is calculated from an image of an assumed subject in the registered subject information described above, and identification processing is performed using this feature data. Also good.

  In the following description, a case will be described in which feature data of a subject to be identified in advance is registered in association with the name of the subject, and the subject name is registered as registered subject information.

Further, as shown in FIG. 5, the recorded video is recorded in association with the event name and shooting location information and shooting date / time information as shooting information.

  The shooting location information can be acquired from GPS (Global Positioning System) and recorded in association with video, as disclosed in Japanese Patent Laid-Open No. 2003-018506.

  The temporal relationship information represents the flow of event items associated with each theme. For example, in the “wedding” flow, events such as “cake sword” and “leave the bride and groom” do not occur before “the bride and groom enter”. The “sword” event occurs. Such a flow of “wedding” such as “Bride and groom entrance” → “Cake entry” → “Bride and groom exit” is associated with event items with information representing temporal relationships.

  The second event item extraction unit 112 uses the shooting location information and shooting date / time information of the event video recorded on the recording medium 108 to handle the video composed of the processing target image input to the control unit 105. To extract theme information.

  Further, the second event item extraction unit 112 sends the control information to the control unit 105 from the extracted theme information other than the event items associated with the extracted event video of the same theme information recorded in the recording medium 108. Event item candidates to be added to the video composed of the input images to be processed are extracted.
