Image display apparatus, image display method, and computer-readable medium

Abstract

According to one embodiment, an image display apparatus includes a position specifying unit, a first display control unit, and a second display control unit. The position specifying unit specifies a retrieval start position indicating an arbitrary place within a predetermined order of images based on a user operation. The first display control unit controls displaying an image corresponding to the retrieval start position. The second display control unit changes the displayed image in the predetermined order.

1 . An image display apparatus comprising:
 a display device configured to display images;   a position specifying unit configured to specify a retrieval start position indicating an arbitrary place within a predetermined order of images based on a user operation;   a first display control unit configured to control displaying an image corresponding to the retrieval start position on the display device; and   a second display control unit configured to change the image displayed on the display device in the predetermined order or a reverse order of the predetermined order.   
     
     
         2 . The apparatus according to  claim 1 , wherein the second display control unit is configured to change the image displayed on the display device in the predetermined order or the reverse order of the predetermined order in response to a user operation. 
     
     
         3 . The apparatus according to  claim 1 , wherein the position specifying unit is configured to specify a plurality of retrieval start positions,
 the first display control unit is configured to control displaying each image corresponding to the plurality of retrieval start positions in display areas differing from one another on the display device, and   the second display control unit is configured to change each image displayed in the display areas in the predetermined order or the reverse order of the predetermined order.   
     
     
         4 . The apparatus according to  claim 3 , which further comprises a display order setting unit configured to set the display order of the images displayed in the display area for each display area, and
 in which the second display control unit is configured to change each image displayed in the display areas in the set display order.   
     
     
         5 . The apparatus according to  claim 3 , wherein the position specifying control unit is configured to specify a first retrieval start position and a second retrieval start position of which place within the predetermined order is higher than that of the first retrieval start position,
 the first display control unit is configured to control displaying an image at the first retrieval start position in a first display area of the display device, and displaying an image at the second retrieval start position in a second display area of the display device, and   the second display control unit is configured to change the image displayed in the first display area in the predetermined order, and to change the image displayed in the second display area in the reverse order of the predetermined order.   
     
     
         6 . The apparatus according to  claim 3 , wherein the position specifying control unit is configured to specify a first retrieval start position and a second retrieval start position, and
 the first display control unit is configured to control displaying an image at the first retrieval start position in a first display area of the display device, to control displaying an image at the second retrieval start position, an image preceding the second retrieval start position, and an image following the second retrieval start position in a plurality of second display areas each having areas smaller than the first display area, and to switch the image at the first retrieval start position displayed in the first display area and the image at the second retrieval start position displayed in one of the second display areas in response to a user operation.   
     
     
         7 . The apparatus according to  claim 1 , which further comprises an information display control unit configured to control displaying retrieval position information visually indicating the retrieval order corresponding to the image displayed on the display device in the predetermined order by associating the retrieval position information with the image in a prescribed display form. 
     
     
         8 . An image display method comprising:
 specifying a retrieval start position indicating an arbitrary place within a predetermined order of images;   displaying an image corresponding to the retrieval start position on a display device; and   changing the image displayed on the display device in the predetermined order or a reverse order of the predetermined order.   
     
     
         9 . A computer-readable medium having stored thereon an image display program which is executable by a computer, the image display program controlling the computer to execute functions of:
 specifying a retrieval start position indicating an arbitrary place within a predetermined order of images;   displaying an image corresponding to the retrieval start position on a display device; and   changing the image displayed on the display device in the predetermined order or a reverse order of the predetermined order.
