Image Display Apparatus, Image Display Method, And Information Storage Medium

Abstract

Provided is an image display apparatus capable of allowing a user to easily recognize an image belonging to a group. A library view image classifying unit ( 134 ) classifies a plurality of images into groups which have a rank order associated therewith. A library view group image layout unit ( 136 ) places a group image corresponding to each of the groups according to the rank order of the groups, along a group image layout reference line provided in a display region. A library view representative image layout unit ( 140 ) places, on a representative image layout region in the display region, an image belonging to any one of the groups falling within a range on the group image layout reference line associated with the representative image layout region, as a representative image. A library view space displaying unit ( 130 ) displays at least part of the display region on a screen.

1 . An image display apparatus for displaying an image illustrating a scene viewed in a line of sight from a viewpoint disposed in a virtual three dimensional space, the image display apparatus comprising:
 target image layout unit configured to place at least one target image on a layout plane in the virtual three dimensional space;   cursor image layout unit configured to place, on the layout plane, a cursor image indicating a closed region;   cursor image moving unit configured to move the cursor image along the layout plane, in response to an operation signal received from a user; and   image positional relation changing unit configured to change a relative positional relation between the cursor image and the target image such that a distance from the viewpoint to the target image becomes smaller than a distance from the viewpoint to the cursor image, in a case where a distance between a position of the cursor image and a position of the target image on the layout plane falls within a predetermined range.   
     
     
         2 . The image display apparatus according to  claim 1 , wherein the image positional relation changing unit is configured to change a distance from the layout plane to the target image. 
     
     
         3 . The image display apparatus according to  claim 1 , wherein the cursor image is larger in size than the target image. 
     
     
         4 . The image display apparatus according to  claim 1 , wherein the cursor image moving unit is configured to bring the cursor image and the target image closer to each other according to a distance between a representative point in the cursor image and a representative point in the target image, in a case where the distance between the position of the cursor image and the position of the target image on the layout plane falls within a predetermined range. 
     
     
         5 . An image display method of displaying an image illustrating a scene viewed in a line of sight from a viewpoint disposed in a virtual three dimensional space, the image display method comprising:
 placing at least one target image on a layout plane in the virtual three dimensional space;   placing, on the layout plane, a cursor image indicating a closed region;   moving the cursor image along the layout plane, in response to an operation signal received from a user; and   changing a relative positional relation between the cursor image and the target image such that a distance from the viewpoint to the target image becomes smaller than a distance from the viewpoint to the cursor image, in a case where a distance between a position of the cursor image and a position of the target image on the layout plane falls within a predetermined range.   
     
     
         6 . A non-transitory, computer-readable information storage medium storing a program for causing a computer to function as an image display apparatus for displaying an image illustrating a scene viewed in a line of sight from a viewpoint disposed in a virtual three dimensional space, the program further causing the computer to function as:
 target image layout unit configured to place at least one target image on a layout plane in the virtual three dimensional space;   cursor image layout unit configured to place, on the layout plane, a cursor image indicating a closed region;   cursor image moving unit configured to move the cursor image along the layout plane, in response to an operation signal received from a user; and   image positional relation changing unit configured to change a relative positional relation between the cursor image and the target image such that a distance from the viewpoint to the target image becomes smaller than a distance from the viewpoint to the cursor image, in a case where a distance between a position of the cursor image and a position of the target image on the layout plane falls within a predetermined range.
