The display device is provided with an image display section ( 17 ) which displays an image; a touch panel ( 18 ) which is disposed on the surface of the image display section ( 17 ); a storage section ( 11 ) which associates selection icons which show the operation state of an operator such as if the operator has bare hands or gloved-hands, with the size of the operation icons showing operation choices, and stores the result; and a control section ( 20 ) which displays the plurality of selection icons on the image display section ( 17 ), and displays the operation icon at the size associated with the selection icon selected by the operator, on the image display section ( 17 ).
1 . A display apparatus comprising:
an image display section that displays data;
a touch panel that is disposed on a surface of the image display section;
a storage section that stores an image that is displayed on the image display section; and
a control section that detects an area touched by an operator of the touch panel, reads an image from the storage section based on a detection result, and displays that image on the image display section, wherein:
the storage section stores in a mutually associated fashion a selection icon indicating an operating state of the operator and an operation icon indicating an operation choice:
a size of the operation icon differs for each selection icon; and
the control section displays the plurality of selection icons on the image display section, and displays an operation icon of a size associated with a selection icon selected by the operator on the image display section.
2 . The display apparatus according to claim I, wherein:
the storage section stores the selection icon selected most recently; and
the control section displays an operation icon of a size associated with a selection icon stored in the storage section on the image display section until receiving a command that causes the selection icon to be displayed on the image display section from the operator.
3 . The display apparatus according to claim 1 , wherein the control section performs display on the image display section with sizes of each of the operation icon made mutually different, and the higher control section sets detection sensitivity of the touch panel, the larger the operation icon is.
4 . The display apparatus according to claim 1 , wherein:
the storage section stores a plurality of display screens that include the operation icon associated with each of the selection icon;
display areas of the operation icon in each of the display screen are set so as to be mutually different; and
the control section displays a display screen associated with a selected selection icon on the image display section.
5 . The display apparatus according to claim 2 , wherein the control section displays the selection icon on the image display section when having detected a predetermined operation.
6 . The display apparatus according to claim 2 , further comprising a button for displaying the selection icon on the image display section.
7 . The display apparatus according to claim 1 , wherein:
a display area of the operation icon is rectangular;
the control section performs display on the image display section with sizes of each of the selection icon made mutually different; and
a ratio between a long side and a short side of the operation icon associated with a large selection icon is closer to 1 than a ratio between a long side and a short side of the operation icon associated with a small selection icon.
8 . The display apparatus according to claim 1 , wherein, in each display screen in which the operation icon is included a plurality and mutually identical number of operation icons are included, operation icons are arranged in in rows of n columns in each of the display screen, and a product of the in and the n is equal in all of the display screens.
