Tilt adjustable perspective icons display device and non-transitory computer readable medium

A non-transitory computer readable medium with a display control program recorded thereon, the display control program allowing a computer including a display section that includes a display and a touch panel, the display section being designed so that a tilt of a display surface of the display is variable, a storage section that previously stores a plurality of images each representing each of a plurality of icons of a same shape in which a ratio between a length in a predetermined first direction and a length in a second direction orthogonal to the first direction on the display surface of the display is predetermined, and a processor to function as:

• an acceptance section accepting an instruction to be input through the touch panel and a display control section controlling a display operation of the display,
• the display control program further allowing the computer to function so that the display control section allows the display:
• (1) when the acceptance section accepts through the touch panel an instruction to display an acceptance screen for accepting an instruction of selecting to allow the plurality of icons to be displayed in a normal display manner or a different display manner different from the normal display manner, to display the acceptance screen;
• (2) when the acceptance section accepts through the touch panel the instruction of selecting to allow the plurality of icons to be displayed in the normal display manner, to display, by using the plurality of images previously stored in the storage section, the plurality of icons whose lengths in the first direction and whose lengths in the second direction are not changed;
• and
• (3) when the acceptance section accepts through the touch panel the instruction of selecting to allow the plurality of icons to be displayed in the different display manner, to display, by using the plurality of images previously stored in the storage section, the plurality of icons of the same shape whose lengths in the first direction are extended equally and the lengths in the second direction are extended equally such that a degree of the extension increases as distance from one end of the display surface in the first direction decreases;
• (4) when the acceptance section accepts through the touch panel the instruction of selecting to allow the plurality of icons to be displayed in the different display manner, the display control section additionally makes a display density of the plurality of icons higher than a display density of the plurality of icons represented by the plurality of images previously stored in the storage section.

A display device comprising:

• a display section that includes a display and a touch panel, the display section being designed so that a tilt of a display surface of the display is variable;
• a storage section that previously stores an image representing an operation screen containing a plurality of icons in which a ratio between a length in a predetermined first direction and a length in a second direction orthogonal to the first direction on the display surface of the display is predetermined;
• a control unit that includes a processor and functions, when the processor executes a display control program, as an acceptance section accepting an instruction to be input through the touch panel, and as a display control section controlling a display operation of the display;
• a tilt detecting section capable of detecting the tilt of the display surface, wherein as a difference between an angle of the tilt detected by the tilt detecting section and a predetermined angle increases, the display control section increases a dimension of the operation screen by which the operation screen is extended to the first direction;
• and
• the display control section allowing the display:
• (1) when the acceptance section accepts through the touch panel an instruction to display an acceptance screen for accepting an instruction of selecting to allow the operation screen to be displayed in a normal display manner or a different display manner different from the normal display manner, to display the acceptance screen;
• (2) when the acceptance section accepts through the touch panel the instruction of selecting to allow the operation screen to be displayed in the normal display manner, to display, by using the image previously stored in the storage section, a first operation screen in which a length in the first direction of the operation screen and a length in the second direction of the operation screen are not changed;
• and
• (3) when the acceptance section accepts through the touch panel the instruction of selecting to allow the operation screen to be displayed in the different display manner, to display, by using the image previously stored in the storage section, a second operation screen in which the length in the first direction of the operation screen is extended and the length in the second direction of the operation screen is extended such that a degree of the extension increases as distance from one end of the display surface in the first direction decreases.
