Abstract

The display control apparatus specifies a position on the display screen that is specified by the user according to an instruction from the user, and displays information on the display screen that is set by the specified first position and second position, and that indicates data to be displayed from among a plurality of items of data on the display screen. When the user further specifies a third position, the display control apparatus determines whether an instruction from the user for specifying the third position is a specified instruction that differs from an instruction for specifying the second position. When it is determined that the instruction is the specified instruction, the display control apparatus displays data, from among the plurality of items of data, that corresponds to the information displayed on the display screen.

Claims

1. A display control apparatus comprising:

a specifying unit configured to specify a position on a display screen which is designated by a user, according to an instruction by the user;

a first display control unit configured to cause information prepared based on first and second positions on the display screen which are specified by said specifying unit, the information indicating data to be displayed among a plurality of items of data, to be displayed on the display screen;

a determination unit configured to, if said specifying unit specifies a third position on the display screen according to the user'"'"'s instruction based on the information displayed by said first display control unit, determine whether the user'"'"'s instruction for designating the third position is a predetermined instruction that are different from the user'"'"'s instruction for designating the second position, based on the second and third positions on the display screen; and

a second display control unit configured to, if said determination unit determines that the user'"'"'s instruction for designating the third position is the predetermined instruction, cause data corresponding to the information displayed by said first display control unit, among the plurality of items of data to be displayed on the display screen.

2. The display control apparatus according to claim 1, wherein said first display control unit specifies a number of item of data corresponding to the first and second positions and causes information indicating the specified number of item of data to be displayed on the display screen, and said second display control unit causes data corresponding to the number of item of data that is displayed on the display screen to be displayed on the display screen.

3. The display control apparatus according to claim 1, wherein the plurality of items of data are a plurality of images stored in a memory, said first display control unit causes a thumbnail image of an image corresponding to the first and second positions to be displayed as the information on the display screen, and said second display control unit causes an image corresponding to the thumbnail image displayed on the display screen among the plurality of images stored in the memory to be displayed on the display screen.

4. The display control apparatus according to claim 1, wherein said first display control unit causes the information corresponding to a distance between the first and second positions on the display screen, which are specified by said specifying unit, to be displayed on the display screen.

5. The display control apparatus according to claim 1, wherein said specifying unit specifies a move on the display screen, the move being designated by the user.

6. The display control apparatus according to claim 5, wherein said second display control unit, if completion of the move on the display screen which is designated by the user is confirmed by specifying by said specifying unit, causes data corresponding to the information displayed by said first display control unit to be displayed on the display screen.

7. The display control apparatus according to claim 5, wherein said determination unit determines whether the user'"'"'s instruction for designating the third position is the predetermined instruction, based on a direction of move from the second position to the third position on the display screen.

8. The display control apparatus according to claim 7, wherein said determination unit determines whether the direction of the move from the second position to the third position on the display screen is a second direction different from a first direction from the first position to the second position.

10. A storage medium storing a program that is read by a computer to cause the computer to function as the display control apparatus according to claim 1.

9. A display control method comprising:

specifying a position on a display screen which is designated by a user, according to an instruction by the user;

causing information prepared based on first and second positions on the display screen which are specified, the information indicating data to be displayed among a plurality of items of data, to be displayed on the display screen;

if a third position on the display screen is specified according to the user'"'"'s instruction based on the displayed information, determining whether the user'"'"'s instruction for designating the third position is a predetermined instruction that are different from the user'"'"'s instruction for designating the second position, based on the second and third positions on the display screen; and

if it is determined that the user'"'"'s instruction for designating the third position is the predetermined instruction, causing data corresponding to the displayed information, among the plurality of items of data to be displayed on the display screen.
