JP 2004-194338 A

  However, it is not considered to create an advanced slide show as if it were made by a designer.

  An object of the present invention is to generate an advanced slide show.

  The slide show generating apparatus according to the present invention includes a moving image data storage means for storing moving image data, and a drawing position of a still image drawn on each frame constituting the moving image represented by the moving image data stored in the moving image data storage means. A scenario data storage means for storing scenario data for defining a still picture data, a still picture data input means for inputting still picture data, a still picture represented by still picture data inputted from the still picture data input means, Drawing at a drawing position defined by the scenario data stored in the scenario data storage means, which is the position in the frame constituting the video represented by the video data stored in the data storage means, A moving image generating means for generating display moving image data is provided.

  The present invention also provides a control method suitable for the slide show generating apparatus. That is, this method stores moving image data, stores scenario data that defines the drawing position of the still image drawn on each frame constituting the moving image represented by the stored moving image data, and stores the still image. The data is input, and the still image represented by the inputted still image data is defined by the stored scenario data, which is the position in the frame constituting the moving image represented by the stored moving image data. The display moving image data is generated by drawing at the drawing position.

  The present invention also provides a program for realizing the control method of the slide show generating apparatus.

  According to the present invention, moving image data and scenario data are stored. The scenario data defines the position on the frame constituting the moving image represented by the moving image data and the position where the still image is drawn. When still image data is input, a still image represented by the still image data is drawn at a position defined by the scenario data, and display moving image data is generated.

  By inputting still image data, a moving image in which a still image represented by the input still image data is drawn is displayed at a predetermined position of a frame constituting the moving image. You can get a slideshow in which still images are combined with videos as if they were made by a designer.

  You may further provide the display control means which controls a display apparatus to display the moving image for a display represented with the moving image data for a display produced | generated by the said moving image production | generation means.

  The moving image data is, for example, moving image data of at least one of background moving image data and foreground moving image data. The foreground video data represents the video that is displayed in the foreground when multiple images are superimposed, and when a still image is drawn, the portion where the still image is drawn can be seen It is.

  The scenario data stored in the scenario data storage means may include, for example, still image effect information (transparency, rotation angle, etc.) in addition to the still image drawing position.

  The moving image data may be accompanied by sound data representing sound output corresponding to moving image display. Sound suitable for video can be output.

  FIG. 1 shows an embodiment of the present invention and is a block diagram showing an electrical configuration of a slide show generating apparatus.

  The slide show generating apparatus according to this embodiment displays a still image represented by still image data recorded on a digital recording medium such as a memory card brought by the user (or other digital medium such as a CD: Compact Disk). A so-called elaborate slide show is generated by drawing on a background video.

  The memory 1 of the slide show generation apparatus stores sound data, background image data, scenario data, and a program for controlling operations described later. The background moving image data indicates a moving image displayed on the background of a still image. The sound data outputs the sound that matches the background video. The scenario data defines the position at which a still image provided by the user is drawn on the image of each frame constituting the background moving image. The sound data, background image data, and scenario data read from the memory 1 are input to the moving image synthesis engine 3.

  The slide show generating apparatus is provided with a memory card reader 4. This memory card reader 4 is loaded with a memory card brought by the user. Still image data stored in the memory card is read and applied to the moving image synthesis engine 3.

  The operation signal output from the operation device 2 is given to the moving image synthesis engine 3. The operation device 2 selects still image data used for the slide show among the still image data stored in the memory card.

  Display moving image data representing a slide show generated by the moving image synthesis engine 3 is given to the display device 5. A slide show is displayed on the display screen of the display device 5. The sound data is given to the speaker 6. A sound suitable for the slide show is output from the speaker 6.

  The display moving image data representing the generated slide show may be recorded on a recording medium such as a DVD. In that case, the recording device will be provided in the slide show generating device.

  FIG. 2 shows an image of each frame constituting the background image represented by the background moving image data stored in advance in the memory 1, its frame number, and a waveform diagram of the sound represented by the sound data.

  In the background video, the images of each frame constituting the background video are switched about every 1/30 seconds. The background video appears to move as the images of each frame change every 1/30 seconds. A frame number is assigned to each frame image constituting the background moving image. Frame numbers 1, 2, 3, 4, 5, 6, etc. are assigned to the images 11, 12, 13, 14, 15, 16, etc. of each frame constituting the background moving image, respectively.

  The sound data is defined so as to output a sound suitable for the background moving image.

  FIG. 3 is an example of scenario data.

  The scenario data prescribes the drawing of a still image in one frame image constituting a moving image. The drawing position number, the combined position X, the combined position Y, and the like correspond to the frame number of each frame image forming the moving image. Image width, image height, transparency and rotation angle are specified.

  The drawing position number is a number for identifying the drawing position of a still image in one frame image constituting a moving image. Since the drawing position number corresponding to frame number 1 is only 1, it can be seen that there is one still image drawn on the image of frame number 1. On the other hand, since the drawing position numbers corresponding to frame number 3 are 1 and 2, it can be seen that there are two still images drawn on the image of frame number 3.

  The composition position X and the composition position Y define the drawing position of a still image. The still image is positioned so that the upper left point of the still image to be drawn is aligned with the coordinates defined by the combined position X and the combined position Y.

  The image width and image height specify the size of the still image. The still image is subjected to enlargement processing or reduction processing so that the still image to be drawn can be fitted in an area defined by the image width and the image height.

Transparency defines the transparency of still images. The higher the transparency (closer to 1.0), the higher the proportion of still images that should be drawn, and the lower the proportion of background images that can be seen. The lower the transparency, the lower the proportion of still images that should be drawn. And the percentage of the background image that can be seen increases. If the transparency is 1.0, only the still image can be seen and the background image cannot be seen where the background image and the still image overlap. The pixel value of the display image (one frame image constituting the generated display moving image) is obtained based on Equation 1 using transparency.
(Pixel value of display image) = (pixel value of background image) × (1−transparency) +
(Pixel value of still image) x (Transparency) Formula 1

  The rotation angle defines the rotation angle of the still image. The relative rotation angle with respect to the still image drawing area displayed in the still image drawing area defined by the above-described combining position X, combining position Y, image width, and image height is shown.

  4 to 7 are examples of images (display images) constituting a moving image in which a still image is drawn.

  FIG. 4 is a display image of frame number 1.

  The display image 21 with frame number 1 is the still image stored in the memory card brought by the user according to the scenario data with frame number 1 among the above-described scenario data. 31 is drawn. In the display image 21 of frame number 1, a still image 31 of one frame is drawn on the background image 11. Since the still image 31 has a transparency of 0.85, the background moving image 11 can be seen through a little.

  FIG. 5 is a display image of frame number 2.

  Similarly to the image 21 of the frame number 1, the display image 22 of the frame number 2 is drawn on the background moving image 12 according to the scenario data of the frame number 2 among the scenario data described above. It is what. In the display image 22 of frame number 2, a still image 31 is drawn on the background image, but the drawing position is shifted. Also, the background moving image 12 is not exactly the same as the background moving image 11 with frame number 1, and as described above, it appears to move by switching at 1/30 seconds.

  FIG. 6 is a display image of frame number 3.

  The display image 23 of frame number 3 also has still images 31 and 32 drawn on the background moving image 13 of frame number 3 according to the scenario data of frame number 3. In the scenario data of frame number 3, two drawing position numbers are defined, and two ranges for drawing a still image are defined, so that two still images 31 and 32 are included in the image 23. Since the transparency of one still image 31 is 0.91, the background moving image 13 can be seen through a little, but since the transparency of the other still image 32 is 1.0, the background moving image 13 cannot be seen through at all.

  FIG. 7 is a display image of frame number 4.

  Similarly to the display image 23 of frame number 3, the display image 24 of frame number 4 includes two frames of still images 31 and 32. One still image 31 is shifted in position between the display image 23 with frame number 3 and the display image 24 with frame number 4, but the other still image 32 is for display with frame number 3. The position is not shifted between the image 23 and the display image 24 with frame number 4. Therefore, one image 31 moves between the display image 23 and the display image 24, but the other image 32 does not move. However, the background image 13 and the background image 14 are not exactly the same, and the background image moves.

  Such display images 21 to 24 are generated and switched every 1/30 seconds to generate a slide show. Moreover, since there is a background video, the person who is viewing the slide show represented by the display video data has the impression that the designer has generated it.

  FIG. 8 is a flowchart showing a processing procedure of the slide show generating apparatus.

  Sound data, background image data, and scenario data are read from the memory 1 (step 41). Scenario data corresponding to the frame number of the image constituting the background moving image represented by the background moving image data is found (step 42). The still image data read by the memory card reader 4 is read (step 43). Enlargement processing, reduction processing, rotation processing, and the like are performed so that the still image represented by the read still image data can be fitted into the drawing area of the still image defined by the scenario data (step 44). The still image that has been subjected to the enlargement process, the reduction process, the rotation process, and the like is drawn on the image constituting the background moving image and is drawn in the still image drawing area defined by the scenario data (step 45). Steps 43 to 45 are repeated until a display image for one frame of the display moving image is completed (step 46).

  When the display image for one frame of the display moving image is completed (YES in step 46), the image on which the still image is drawn is stored (step 47). Until all the display moving images corresponding to the background moving image are generated, the processing from step 42 to step 47 is repeated for each frame constituting the display moving image (step 48). The generated slide show is displayed on the display device (step 49).

  9 to 12 show another embodiment.

  In the embodiment described above, a slide show is generated using a background moving image. In the embodiment described below, a slide show is generated using a foreground moving image.

  FIG. 9 is a block diagram illustrating an electrical configuration of the slide show generation apparatus. In this figure, the same components as those shown in FIG.

  The slide show generating apparatus according to this embodiment includes two moving image synthesis engines 3 and 7. As described above, the first moving image synthesis engine 3 generates a slide show using the background moving image data. The moving image data representing the generated slide show is given from the first moving image synthesis engine 3 to the second moving image synthesis engine 2. Scenario data is also given to the second moving image synthesis engine 7.

  As described above, the slide show generating apparatus according to this embodiment is provided with the memory 8 in which foreground moving image data is stored in addition to the memory 1 in which background image data and the like are stored. The foreground moving image data stored in the memory 8 is given to the second moving image synthesis engine 7 to generate a slide show in which the foreground moving images are superimposed. The generated slide show is displayed on the display device 5.

  FIG. 10 is an example of one frame image (foreground image) constituting the foreground moving image.

  The foreground image 50 is an image that is superimposed on the foreground such as a background image or a still image when a slide show is performed. The foreground image 50 includes a first area 52 and a second area 52 obtained by removing the first area 52 from the foreground image 50. The first region 51 and the second region 52 are different in transparency, and the second region 52 is set so as to show through when the images are superimposed. Of course, the reverse is also possible.

  The foreground image 50 also includes a decorative image 53.

  By changing the foreground image 50 every 1/30 seconds, the foreground video appears to move.

  FIG. 11 is an example of the still image 60. A foreground image 50 is superimposed on the still image 60.

  FIG. 12 is an example of one frame image constituting the display moving image.

  The single image 70 constituting the display moving image is generated by superimposing the foreground image 50 on the still image 60 as described above. In this way, by generating a large number of images 70 constituting the display moving image, a slide show in which the foreground moving image is displayed in the foreground can be generated.

The pixel value of the display image can be calculated based on Equation 2.
(Pixel value of display image) = [(pixel value of background image) × (transparency specified for still image) +
(Still image pixel value) x (transparency specified for still image)] x
(1-Transparency of foreground image)
+ (Pixel value of foreground image) x (transparency of foreground image) Equation 2

  As can be seen from Equation 2, when a slide show is generated using a background image and a foreground image (or only the foreground image), the scenario data defines not only the transparency of the still image but also the transparency of the foreground image. It goes without saying that it is necessary to do this.
