Display control apparatus, display control method, and program

Abstract

A display control apparatus: in a virtual three-dimensional space in which is disposed a three-dimensional model of an object contained in a moving image picked up by performing successive imaging operations once by using an imaging device, draws a plurality of thumbnail images extracted from the moving image to the respective positions of the imaging device at the time when the thumbnail images were picked up and draws information that relates the thumbnail images in order in which they were picked up, thereby generating a bird's eye-display image which provides a bird's-eye-view drawing of the virtual three-dimensional space containing the three-dimensional model and the thumbnail images; and causes a display unit to display the bird's eye-display image.

What is claimed is: 
     
         1 . A display control apparatus comprising:
 a storage unit that stores a moving image picked up by performing successive imaging operations once by using an imaging device;   a display image generation unit that draws a plurality of thumbnail images extracted from the moving image to the respective positions of the imaging device at the time when the thumbnail images were picked up in a virtual three-dimensional space in which a three-dimensional model of an object contained in the moving image is disposed and draws information that relates the thumbnail images in order in which they were picked up in the virtual three-dimensional space, thereby generating a bird's eye-display image which provides a bird's-eye-view drawing of the virtual three-dimensional space containing the three-dimensional model and the thumbnail images; and   a display control unit that causes a display unit to display the bird's eye-display image.   
     
     
         2 . The display control apparatus according to  claim 1 , wherein
 the storage unit stores movement track information which represents a movement track of the imaging device at the time when the imaging device picked up the moving image, as additional information of the moving image and   the display image generation unit draws the thumbnail images in the virtual three-dimensional space at the respective positions of the imaging device at the time when the thumbnail images were picked up based on the movement track information.   
     
     
         3 . The display control apparatus according to  claim 2 , wherein
 the information which relates the thumbnail images in order in which they were picked up is a movement track line representing the movement track of the imaging device at the time when the imaging device picked up the moving image, and   the display image generation unit draws the movement track line in the virtual three-dimensional space in such a manner as to connect the thumbnail images in the order in which the thumbnail images were picked up based on the movement track information.   
     
     
         4 . The display control apparatus according to  claim 3 , wherein the display image generation unit draws the movement track line connecting the thumbnail images in various line types in accordance with contents or imaging situations of the moving image between the thumbnail images. 
     
     
         5 . The display control apparatus according to  claim 1 , wherein the display image generation unit draws an alternative image which represents the contents or imaging situations of at least some of the thumbnail images to the drawing positions of the thumbnail images in place of the thumbnail images. 
     
     
         6 . The display control apparatus according to  claim 5 , wherein the display image generation unit:
 changes a size of the thumbnail images to be drawn in accordance with the drawing positions of the thumbnail images in the virtual three-dimensional space; and   if the size of the thumbnail images to be drawn is a predetermined size or less, draws the alternative image in place of the thumbnail images.   
     
     
         7 . The display control apparatus according to  claim 1 , wherein the display image generation unit draws metadata about the thumbnail images in the virtual three-dimensional space in a condition where the metadata is related to the thumbnail images. 
     
     
         8 . The display control apparatus according to  claim 1 , further comprising an image editing unit that edits the moving image in response to user operations on the thumbnail images or the three-dimensional model in the bird's eye-display image shown on the display unit. 
     
     
         9 . The display control apparatus according to  claim 1 , further comprising an image editing unit that generates, in response to specification of an angle in the bird's eye-display image shown on the display unit, the moving image as viewed at the specified angle. 
     
     
         10 . The display control apparatus according to  claim 1 , further comprising an image retrieval unit that retrieves the image containing the three-dimensional model which is the same as or similar to the three-dimensional model selected from the bird's eye-display image shown on the display unit or an object corresponding to the three-dimensional model. 
     
     
         11 . A display control method comprising the steps of:
 drawing a plurality of thumbnail images extracted from a moving image picked up by performing successive imaging operations once by using an imaging device to the respective positions of the imaging device at the time when the thumbnail images were picked up in a virtual three-dimensional space in which a three-dimensional model of an object contained in the moving image is disposed and draws information that relates the thumbnail images in order in which they were picked up in the virtual three-dimensional space, thereby generating a bird's eye-display image which provides a bird's-eye-view drawing of the virtual three-dimensional space containing the three-dimensional model and the thumbnail images; and   causing a display unit to display the bird's eye-display image.   
     
     
         12 . A program for causing a computer to perform the steps of:
 drawing a plurality of thumbnail images extracted from a moving image picked up by performing successive imaging operations once by using an imaging device to the respective positions of the imaging device at the time when the thumbnail images were picked up in a virtual three-dimensional space in which a three-dimensional model of an object contained in the moving image is disposed and draws information that relates the thumbnail images in order in which they were picked up in the virtual three-dimensional space, thereby generating a bird's eye-display image which provides a bird's-eye-view drawing of the virtual three-dimensional space containing the three-dimensional model and the thumbnail images; and   causing a display unit to display the bird's eye-display image.
