Abstract

An apparatus includes a memory, a processor, a control unit and an instruction unit. The control unit controls display on a display unit on which an image based on received image data is displayed. The instruction unit provides an instruction to switch a display size of the image on the display unit. When the instruction unit provides the instruction, in a state in which the image before the switching is performed is displayed on the display unit, the control unit causes display of a first object visually indicating a second display size of the image that is to be displayed on the display unit, the second display size being a size after the switching is performed, and, when the second display size is determined on the basis of the instruction from the instruction unit, the control unit causes display of the image based on the second display size.

1 . An apparatus comprising:
 a memory; and   a processor in communication with the memory, the processor configured to control;   a control unit configured to control display on a display unit on which an image based on received image data is displayed; and   an instruction unit configured to provide an instruction to switch a display size of the image on the display unit,   wherein, in a case where the instruction unit provides the instruction, the control unit causes display, in a state in which the image having a first display size before the switching is performed is displayed on the display unit, of a first object visually indicating a second display size of the image that is to be displayed on the display unit, the second display size being a size after the switching is performed, and, in a case where the second display size is determined on the basis of the instruction from the instruction unit, the control unit causes display of the image based on the second display size.   
     
     
         2 . The apparatus according to  claim 1 ,
 wherein the display unit includes a plurality of layers including a first layer in which the image is disposed, and   wherein, in a case where the instruction from the instruction unit is started, the control unit causes the first object visually indicating the second display size of the image obtained after the switching is performed, to be disposed in a second layer that is a layer higher than the first layer on which the image is disposed.   
     
     
         3 . The apparatus according to  claim 2 ,
 wherein, in a case where the instruction from the instruction unit is started, the control unit causes a second object overlying the image to be disposed in a third layer that is a layer higher than the first layer on which the image is disposed.   
     
     
         4 . The apparatus according to  claim 3 ,
 wherein the second object overlying the image is transparent.   
     
     
         5 . The apparatus according to  claim 1 ,
 wherein, in the case where the second display size is determined based on the instruction from the instruction unit, if the first display size of the image before the instruction is performed is equal to the second display size of the image after the instruction is performed, the control unit causes the display unit not to redisplay the image.   
     
     
         6 . The apparatus according to  claim 1 ,
 wherein the display unit includes a touch panel,   wherein the instruction unit includes an instruction object displayed on the touch panel, and   wherein touching of the instruction object indicates an instruction to switch the first display size of the image, and a release of the touch from the instruction object causes the second display size to be determined.   
     
     
         7 . The apparatus according to  claim 6 ,
 wherein the instruction object is divided into more than one part, and each part is associated with a display size of the image, and   wherein the control unit causes the first object visually indicating a second display size of the image that is to be displayed on the display unit after the switching is performed, to be displayed on the display unit in accordance with a position at which the instruction object is touched.   
     
     
         8 . A method comprising:
 controlling display on a display unit on which an image based on received image data is displayed; and   providing an instruction to switch a display size of the image on the display unit,   wherein, in the controlling of display, in a case where the instruction is provided, in a state in which the image having a first display size before the switching is performed is displayed on the display unit, a first object visually indicating a second display size of the image that is to be displayed on the display unit, the second display size being a size after the switching is performed, is displayed and, in a case where the second display size is determined on the basis of the instruction, the image is displayed on the basis of the second display size.   
     
     
         9 . The method according to  claim 8 ,
 wherein the display unit includes a plurality of layers including a first layer in which the image is disposed, and   wherein, in the controlling of display, in a case where the instruction is started, the first object visually indicating the second display size of the image obtained after the switching is performed is disposed in a second layer that is a layer higher than the first layer on which the image is disposed.   
     
     
         10 . The method according to  claim 9 ,
 wherein, in the controlling of display, in a case where the instruction is started, a second object overlying the image is disposed in a third layer that is a layer higher than the first layer on which the image is disposed.   
     
     
         11 . The method according to  claim 10 ,
 wherein the second object overlying the image is transparent.   
     
     
         12 . The method according to  claim 8 ,
 wherein, in the controlling of display, in the case where the second display size is determined based on the instruction, in a case where the first display size of the image before the instruction is performed is equal to the second display size of the image after the instruction is performed, the display unit does not redisplay the image.   
     
     
         13 . The method according to  claim 8 ,
 wherein the display unit includes a touch panel,   wherein, in the providing of an instruction, an instruction object displayed on the touch panel provides the instruction, and   wherein touching of the instruction object indicates an instruction to switch the first display size of the image, and a release of the touch from the instruction object causes the second display size to be determined.   
     
     
         14 . The method according to  claim 13 ,
 wherein the instruction object is divided into more than one part, and each part is associated with a display size of the image, and   wherein, in the controlling of display, the first object visually indicating a second display size of the image that is to be displayed on the display unit after the switching is performed is displayed on the display unit in accordance with a position at which the instruction object is touched.   
     
     
         15 . A computer-readable recording medium that causes a computer to perform the display control method according to  claim 8 .
