Description

  The present invention relates to an image display system, method, and program, and more particularly, to an image display system, method, and program for displaying a moving image series based on a template.

2. Description of the Related Art Conventionally, a template for printing and displaying a composite image by inserting an arbitrary image (user image) into a previously created image (default image) is known (see, for example, Patent Document 1).
JP-A-9-269999

By the way, it is possible to extract a still image (referred to as “still image” when referring to “image” in this specification) from a moving image series.
It is an object of the present invention to provide an image display system, method, and program that can easily extract an image from a moving image series and display it in various forms.

  In order to achieve the above object, an image display system according to the present invention includes a template selection means for selecting a template defining a plurality of insertion areas for inserting a moving image sequence, and a moving image selection for selecting a moving image sequence. And a condition setting means for setting a first condition for extracting the first image group without associating with each of the plurality of insertion regions of the selected template from the selected moving image series And a second image group including the same number of images as the plurality of insertion areas based on the set first condition, a predetermined second condition, and the number of the plurality of insertion areas, from the moving image series. And a display unit configured to extract and display a plurality of images included in the extracted second image group in a one-to-one manner in the plurality of insertion regions. By displaying an image extracted from a moving image series by inserting it into a template, the image extracted from the moving image series can be easily displayed in various forms. Compared to selecting an image to be inserted into a plurality of insertion areas defined in the template in a one-to-one correspondence with the insertion area from a video sequence, the images are selected together without being associated with each of the plurality of insertion areas. It is easy. Accordingly, first, images to be inserted into a plurality of insertion areas are narrowed down together under a first condition set by the user, and then the same number of images as the insertion areas of the template are narrowed down under the first condition. Are extracted under a predetermined second condition. Further, the second image group extracted under the second condition and the plurality of insertion regions of the template are associated one-to-one, and the second image group is inserted into the plurality of insertion regions of the template and displayed. By such a series of processing, it becomes easy to extract from the moving image series an image group that is associated one-to-one with a plurality of insertion regions of the template.

  Furthermore, in the image display system according to the present invention, the first condition is a reproduction period for specifying a continuous first image group included in the moving image series. Since it is sufficient to set the reproduction period, it is easy to extract an image group that is associated with a plurality of insertion regions of the template on a one-to-one basis from a moving image series.

  Furthermore, in the image display system according to the present invention, the second condition includes a second image including the same number of images as the plurality of insertion regions at equal intervals from the first image group narrowed down based on the first condition. It is characterized by extracting a group. By extracting images from the first image group at equal intervals, it becomes easy to insert an image group in which the movement of the object of the image is changed into the template.

  Furthermore, the image display system according to the present invention further comprises storage means for storing the template defining the plurality of insertion areas having an order of each other, wherein the display means includes the order of the insertion areas and the second order. The plurality of images included in the second image group are displayed in a one-to-one relationship with the plurality of insertion areas based on the order of the image groups. When the order is determined in advance for a plurality of insertion areas of the template and displayed for insertion, the order of the second image group extracted from the video is associated with the order of the insertion area, and the second image When the group is inserted into a plurality of insertion areas of the template and displayed, the display form of the image extracted from the moving image series can be set in detail in advance.

The functions of the plurality of means provided in the present invention are realized by hardware resources whose functions are specified by the configuration itself, hardware resources whose functions are specified by a program, or a combination thereof. The functions of the plurality of means are not limited to those realized by hardware resources that are physically independent of each other.
Further, the present invention can be specified not only as an apparatus invention, but also as a program invention, a storage medium storing the program, and a method invention.

In the present embodiment, the moving image series file inserted into the template stores still images that are individually compressed within a frame as in the Motion-JPEG format and stored in chronological order, and identifiers such as frame numbers are arranged in chronological order. The description will be made assuming that each image is attached.

  The program executed by the CPU 11 includes an image display program. The image display program inserts an image extracted from the moving image series file designated by the user into the insertion region of the selected template, generates digital image data of a composite image, changes color space, resolution conversion processing, half Perform tone processing, interlace processing, and the like to generate print data.

  The screen display unit 17 displays various selection screens for the user to obtain a desired print result and a digital image of a composite image generated by the image display program. The print display unit 19 performs printing based on the print data generated by the image display program. Note that the printer 2 may perform conversion from image data to print data. Various data such as these programs, image files, and templates may be downloaded and input from a predetermined server via a network via the communication unit 18, or may be input from a computer-readable storage medium such as a removable memory. You may read and input.

  FIG. 1 is a schematic diagram showing an outline of an embodiment of the present invention. The image display program stores consecutive images belonging to the reproduction period set by the user from among consecutive images stored in the moving image series file 31 selected by the user and assigned frame numbers corresponding to the shooting time (illustration example). Then, the extraction condition set by the user (in the example of the figure “001010” corresponding to the “start time” of the playback period to the image “001010” corresponding to the “end time” of the playback period) The image is extracted every other image under the “equal interval” extraction condition.) According to the number of insertion areas (in the example shown, insertion areas 32, 33, 34, 35, and 36). An image is extracted and inserted into the insertion area to generate a digital image 37 of a composite image.

FIG. 4 is a schematic diagram showing the data structure of the template, and FIG. 5 is a schematic diagram showing the template. The template is stored in the HDD 14 as a storage unit, the ROM 12 or an internal flash memory (not shown). The template may be input from the outside via the input unit 16 or the communication unit 18. The template 41 includes a print paper size to be printed based on the template, a character display script 42 that defines character allocation, a video display script 43 that defines video sequence allocation, and an image extracted from the video sequence A still image display script 44 and the like for defining the area are stored.
The character display script 42 defines the text to be displayed, its font and size, text frame coordinates indicating the position of the text on the printing paper, and the coordinates of the upper left point and lower right point of the rectangular area. .

  Next, the moving image display script 43 will be described. The moving image display script 43 includes a group ID for specifying a still image script that defines the insertion area, a movie ID that defines the file name of the moving image sequence selected by the user, and the start of the playback period set by the user In addition, a reproduction period that defines a frame number at the end, an image quality, and the like are defined. When the movie ID and the playback period are not set among the data written in these templates, the image display program accepts user settings on a movie file selection screen and a playback period setting screen, which will be described later.

  Next, the still image display script 44 will be described. The still image display script 44 includes a group ID, a photo ID that defines the order of the insertion areas, and a still image frame that indicates the position of the insertion area on the print sheet by the coordinates of the upper left point and the lower right point of the rectangular area. Coordinates, fitting rules that define the positional relationship between images and image frames, alignment rules, and the like are stored. An image extracted from the moving image series file is inserted into the insertion area of the still image display script 44 in which the same numerical value as the group ID stored in the moving image display script 43 is stored in the group ID. For example, a specific example will be described. From the moving image series, the moving image display script 43 with “group ID = 1” is inserted into the insertion area of five still image display scripts 44 stored with “group ID = 1”. Five images to be extracted are inserted. The photo ID is an identifier for uniquely associating each image extracted from the moving image series with any insertion region of the still image display script 44 with the same group ID. The fitting rule and the alignment rule are parameters that specify a position where the image is clipped or a blank space to be left in the image frame when the image is applied to an image frame having a different aspect ratio. In this embodiment, a case has been described in which a numerical value is stored in the group ID for the still image display script. However, an identifier for storing an image such as a still image file name by storing a null value or the like in the group ID. Is stored in the photo ID, a still image can be displayed.

  6 is a template selection screen as template selection means, FIG. 7 is a movie file selection screen as movie selection means, FIG. 8 is a playback period setting screen as extraction condition setting means, FIG. 9 is a frame extraction condition setting screen, and FIG. 10 is a preview screen as display means, and FIG. 11 is a flowchart of the image display program. Hereinafter, details of the image display processing in the image display program of the present embodiment will be described with reference to these drawings.

  When the image display program is activated by the user, the PC 1 displays a template selection screen 51 on the screen display unit 17 and accepts a user operation for selecting a desired template using the keyboard 4 and the mouse 5. The template selection screen 51 displays template thumbnails 52, 53, 54, 55, etc. The template thumbnails may be simply displayed by listing the file names of the templates. In step S101 as a template selection step, when any one of the thumbnails is clicked on the template selection screen 51 to select a template, the image display program reads the selected template 41 into the RAM 13 in step S102.

  Next, the PC 1 displays a movie file selection screen 61 on the image display unit 17. On the movie file selection screen 61, thumbnails 62, 63, 64, 65, 66, 67 of images in the moving image series file stored in the HDD 14 or the like are displayed. This thumbnail may be a thumbnail of the first frame of the moving image series file or a thumbnail of a frame registered in advance by the user. Further, the file names of the moving image series files may be listed and displayed instead of the thumbnails of the specific frames. The user operates the keyboard and mouse 5 to select a desired moving image series file. When a movie series file is selected on the movie file selection screen 61 in step S103 as a movie selection step, the image display program stores the file name of the selected movie series file in the RAM 13.

  Next, the PC 1 displays a reproduction period setting screen 71 on the image display unit 17. The reproduction period setting screen 71 includes a first area 72 for displaying a start image, a second area 73 for displaying an end image, a band-shaped display 74 corresponding to the shooting time of the selected video sequence file, and the band-shaped display. A pointer 75 that points to one point of display and sets the frame number of the image at the start, a pointer 76 that points to one point of the band-like display and sets the frame number of the image at the end, and the like are displayed. When the user operates the keyboard 4 and the mouse 5 and moves the pointers 75 and 76 to the left and right, the image of the frame number pointed to by the pointer is displayed in the first area 72 or the second area 73, and the user Can be set. When the playback period is set on the playback period setting screen 71 in step S104 as the extraction condition setting step, the image display program stores the frame numbers at the start and end of the playback period in the RAM 13.

  Next, the PC 1 displays a frame extraction condition setting screen 81 on the image display unit 17. The frame extraction condition setting screen 81 is a screen on which the user sets how to extract an image to be displayed in the insertion area among the images in the selected reproduction period. “Random”, “Continuous from top”, etc. are displayed. The user operates the keyboard 4 and mouse 5 to select extraction conditions. When the frame extraction condition is set on the frame extraction condition setting screen 81 in step S105, the image display program starts from the image corresponding to the reproduction period of the selected moving image series file in step S106 as a display step. Images corresponding to the frame extraction conditions are extracted by the number of insertion areas specified in the template, and the images are applied in the order of frame numbers in accordance with the order indicated by the photo ID of each insertion area. And a preview screen 91 is displayed on the image display unit 17. Next, the PC 1 generates print data from the digital image data, and outputs the print data to the printer 2. The printer 2 performs printing based on the print data (step S107).

  Here, for example, assuming that “equal intervals” is selected as the frame extraction condition, the processing in step S106 will be specifically described. In the selected moving image series file, when the reproduction period is frame number 10001 to 12000, the quotient 400 calculated by dividing the number 2000 of included images by the number 5 of insertion areas specified by the group ID is the image extraction interval. Then, from the start image (frame number 10001), every 400 images are assigned to the insertion area according to the order indicated by the photo ID. That is, an image with frame number “10001” is inserted into the insertion area with photo ID = 1, an image with frame number “10401” is inserted into the insertion area with photo ID = 2, and a frame number is inserted into the insertion area with photo ID = 3. The image of “10801”, the image of frame number “11201” is assigned to the insertion region of photo ID = 4, and the image of frame number “11601” is assigned to the insertion region of photo ID = 5.

  Further, assuming that “random” is selected as the frame extraction condition, the processing in step S106 will be described. The image display program randomly extracts an image from the frame corresponding to the reproduction period using the generated random number in the selected moving image series file, and assigns the image to the insertion area. At this time, the images may be assigned in order to the insertion area in which the order is defined by the photo ID in the order of extraction, or all the extracted images may be arranged in time series and then assigned to the insertion area in order.

  In the present embodiment, the PC and printer cooperate as the image display system to perform template selection, movie selection, extraction condition setting, and display. However, a display constituted by an LCD, a jog key, and various buttons These may be realized by a stand-alone type printer having an operation panel having a control unit and a control unit. Even when the functions are divided, for example, in a portable information terminal having a low-speed processor and a small-capacity memory such as a mobile phone with a photographing function, the process up to step S103 of the image display program is performed, and a template and a moving image series file are obtained. The PC may perform output up to the stand-alone printer in association with each other, or the step up to step S104 is performed by the PC, and the template in which the “movie ID” is written and the image data belonging to the playback period of the moving image series file are output to the stand-alone printer. Alternatively, in step S106, the stand-alone printer displays the print control information in which an identifier (for example, “001001” as an image file name) specifying an image to be assigned to the template as shown in FIG. 12 is written and the image assigned to the template. May be output to Perform subsequent processing in the control unit of the stand-alone printer, the print display may be performed. Further, although the image display system of the present embodiment has been described as having both the screen display function and the print display function, only the screen display function may be provided.

In the present embodiment, the user selects the playback period as the first condition for narrowing down to the first image group. However, when a plurality of scenes are included in one moving image series file, A specific scene may be selected by the user. Judgment of a scene change can be realized by analyzing the difference between the images of each frame, or by storing the time when the “stop” or “pause” button is pressed at the time of shooting in a moving image series file. In addition, although the start and end images are specified as the setting method of the playback period, the shooting time or the number of frames from the start frame may be specified.
As described above, according to the image display system shown in the embodiment of the present invention, it is possible to easily extract a group of images that correspond one-to-one with a plurality of insertion regions of a template from a moving image series and generate a composite image.
