Next, the operation of the three-dimensional video editing and displaying apparatus according to the first embodiment of the present invention will be described with reference to FIG.

Now, assume that a frame image of a three-dimensional video is being displayed. At this time, the second switch 10 is connected to the display-time-for-editing image storage unit 1, and the display-time-for-editing image storage unit 1 stores the three-dimensional video stored in the image generation unit 7, and The hour display screen generation unit 3 uses this as a display image.

[0022] and then double-click the user to the display screen with the mouse or presses the input button on the GUI (G raphical U ser I nterface ).

Next, the character information input unit 2 receives a character input from the user, and displays a character input with character information such as a font, a character position, a character size, and a character color designated by the user at the time of editing. Notify the screen generation unit 3. Next, the edit-time display screen generator 3 superimposes a character corresponding to the character information input to the character information input unit 2 on the image stored in the edit-time display image storage 1 and outputs the image. In the present embodiment, until the input character information is determined from the character information input unit 2, the characters of the editing display screen generation unit 3 are dynamically changed and displayed according to the input character information.

Next, when the focus is shifted from the character input to the character information input unit 2 and an event for determining the input character information is sent, the characters input until the character is determined, the font and the character size of the input character, and the like. Character attribute information such as the character position and character color is sent to the character information storage unit, and the character information storage unit 4
Then, this information is held. At the same time, the character information storage section 4 outputs these to the scene information storage section 9 together with the three-dimensional video size and display time at this time.

Next, when preview playback is designated by pressing an output video preview button (not shown) on the GUI, the second switch 10 is turned to a user input side such as a play / stop button. The first switch 5 is connected to the output image generation unit 8 side.

At this time, the image generation unit 7 uses the three-dimensional scene information and the three-dimensional data stored in the scene information storage unit 9 to
A two-dimensional image is generated for each frame.

Next, the character generation unit 6 includes a scene information storage unit 9

The pixel position in the generated image is output from the selected pixel position, and the image generation unit 27 selects a three-dimensional object such as a structure or a human character that constitutes the three-dimensional image existing at the pixel position, and stores character information. The section 24 stores a three-dimensional object identifier (ID) for identifying the selected three-dimensional object and input character string information.
Numeral 9 stores the display end time of the character string in correspondence with the associated three-dimensional object.

Next, the operation of the three-dimensional video editing and displaying apparatus according to the second embodiment of the present invention will be described with reference to FIG.

When a preset instruction such as a mouse single click occurs on the display screen, the edit-time display screen generator 23 outputs the clicked pixel position and the display image size, and the output image generator 28 The pixel position in the generated image corresponding to the clicked pixel position is obtained from the ratio between the generated image size and the display image size, and is output to the image generation unit 27.

The image generation unit 27 searches for a three-dimensional object such as a structure or a person at the pixel position output from the output image generation unit 28, and obtains a three-dimensional object identifier (hereinafter referred to as an identifier of the three-dimensional object). Obj-ID) is output to the character information storage unit 24. At this time, if the same three-dimensional object is continuously selected, there is no selected three-dimensional object.

Next, the display-time image storage unit 1 stores the display image, and the character information storage unit 24 stores the Obj-ID. When the character input is determined, the character information storage unit 24 stores the determined character string and Obj-ID, and outputs this to the scene information storage unit 29.

The scene information storage unit 29 stores the corresponding Obj-
For a character string with ID, the time when it disappears from the scene is Ob
Store it in accordance with the j-ID.
