DISPLAY APPARATUS AND IMAGE FORMING APPARATUS

摘要

A coordinate measuring unit (43) measures an x-coordinate, a y-coordinate and a z-coordinate indicating an object position (P) according to a change in the position of an object (F) located within a predetermined distance from a panel surface (55). A display control unit (45) causes a display unit (49) to display a first mark image (61) defining a peripheral range of a position determined by the x- and y-coordinates together with predetermined images (63). The display control unit (45) causes the display unit (49) to display the first mark image (61) such that an area defined by the first mark image (61) becomes smaller as the z-coordinate becomes smaller.

主权项

1. A display apparatus, comprising:
a touch panel unit having a panel surface to be touched and configured to detect a touched position of the panel surface; a display unit configured to display a predetermined image to be depressed via the panel surface; a coordinate measuring unit configured to measure a coordinate in a first direction, a coordinate in a second direction and a coordinate in a third direction of the position of a certain object located within a predetermined distance from the panel surface according to a change in the position of the object with directions defining a coordinate plane on the panel surface as the first and second directions and a direction perpendicular to the panel surface as the third direction; and a display control unit configured to execute a display control for causing the display unit to display a first mark image for defining a peripheral range of a position determined by the coordinate in the first direction and the coordinate in the second direction together with the predetermined image and causing the display unit to display the first mark image such that an area defined by the first mark image becomes smaller as the coordinate in the third direction becomes smaller when the coordinate in the first direction, the coordinate in the second direction and the coordinate in the third direction are measured by the coordinate measuring unit.
