Video image processing device, video image analysis system, method, and program

Abstract

A video image processing device according to the present invention includes a display control means ( 501 ) that causes a display unit to display a trajectory indicating a change in a position of an object in a video image. The display control means ( 501 ) acquires a first request designating a point in the trajectory being displayed, and displays a designated image including the object which it was located at the designated point by superimposing it on an arbitrary background image being displayed on the display unit.

What is claimed is: 
     
         1 . A video image processing device comprising
 a display control unit that causes a display unit to display a trajectory indicating a change in a position of an object in a video image,   wherein the display control unit acquires a first request designating a point in the trajectory being displayed, and displays a designated image including the object which it was located at the designated point by superimposing it on an arbitrary background image being displayed on the display unit.   
     
     
         2 . The video image processing device according to  claim 1 , wherein,
 every time the designated point changes, the display control unit superimposes, on the background image, the designated image including the object which it was located at the designated point.   
     
     
         3 . The video image processing device according to  claim 1 , wherein
 the designated image is an image obtained by cutting out the object from a corresponding image being an image generated when the object was located at the designated point among images included in the video image and,   when superimposing the designated image on the background image, the display control unit superimposes a second designated image together with the designated image on the background image, the second designated image being an image obtained by cutting out another object related to the object from the corresponding image.   
     
     
         4 . The video image processing device according to  claim 3 , wherein
 the another object related to the object draws a trajectory having a predetermined relationship with the trajectory of the object in the video image.   
     
     
         5 . The video image processing device according to  claim 1 , wherein
 the display control unit acquires a second request designating a point in the trajectory being displayed, and switches the background image to a corresponding image being an image generated when the object was located at the designated point among images included in the video image.   
     
     
         6 . The video image processing device according to  claim 1 , wherein
 the display control unit acquires a third request designating one of a point and a section in the trajectory being displayed, and attaches information indicating the designation to an image generated when the object was located at the designated one of the point and the section among images included in the video image, or extracts the image from the video image and outputs the image to outside.   
     
     
         7 . The video image processing device according to  claim 1 , wherein
 the display control unit attaches identification information about the object or information about time corresponding to the designated point, to the designated image, and superimposes the designated image on the background image.   
     
     
         8 . The video image processing device according to  claim 1 , wherein
 the display control unit, in accordance with one of a feature of the object shown in an analysis result obtained by analyzing the video image, a feature of another object related to the object shown in the analysis result, and an elapsed time from a predetermined time, makes a display mode of a part of the trajectory differ from another part or attach information indicating one of the analysis result and the elapsed time to a vicinity of a part of the trajectory.   
     
     
         9 . (canceled) 
     
     
         10 . A video image processing method comprising:
 causing a display unit to display a trajectory indicating a change in a position of an object in a video image; acquiring a first request designating a point in the trajectory being displayed; and   displaying a designated image including the object which it was located at the designated point by superimposing it on an arbitrary background image being displayed on the display unit.   
     
     
         11 . A non-transitory computer-readable recording medium in which a video image processing program is recorded, the video image processing program causing a computer to:
 perform a process of causing a display unit to display a trajectory indicating a change in a position of an object in a video image;   in the process, acquire a first request designating a point in the trajectory being displayed; and   display a designated image including the object which it was located at the designated point by superimposing it on an arbitrary background image being displayed on the display unit.
