1. A display apparatus comprising:
- a display; and
a detector, wherein,when the display displays a first screen on a first layer, andthe detector detects contactless proximity of an object to the display displaying the first screen and first coordinates of the object in contactless proximity to the display displaying the first screen,a first area of the first screen,which includes the first coordinates of the object in contactless proximity to the display and has a predetermined correspondence with the first coordinates,is enlarged to a first enlarged area having a predetermined shape and a predetermined size, and the display displays the first enlarged area on a second layer overlapping the first screen;
while the display is displaying the first enlarged area overlapping the first screen and the detector is detecting the contactless proximity of the object to the display and the first coordinates of the object,when the detector detects the contactless proximity of the object to the display and second coordinates of the object in contactless proximity to the display, the second coordinates being different from the first coordinates and within the first enlarged area,a second area of the first screen,which includes the second coordinates of the object in contactless proximity to the display and has the predetermined correspondence with the second coordinates,is enlarged to a second enlarged area having the predetermined shape and the predetermined size,the second enlarged area is centered at a centering coordinate, wherein a distance between the centering coordinate and the first coordinates is a result of multiplication of a ratio between a display magnification of the first layer and a display magnification of the first enlarged area on the second layer and a relative movement amount of the object from the first coordinates to the second coordinates; and
the display displays the second enlarged area overlapping the first screen;
while the display is displaying the second enlarged area overlapping the first screen and the detector is detecting the contactless proximity of the object to the display and the second coordinates of the object,when the detector detects a contact of the object to the display and third coordinates of the object contacting the display within the second enlarged area,an item displayed within the second enlarged area and at the third coordinate of the object contacting the display is selected,wherein the object in contactless proximity to the display is in a plane parallel to the display within a prescribed distance threshold value with respect to the display.

Abstract
A display device includes a display section which displays an image in a screen, a proximity detecting section which detects proximity of a finger to the screen, an image generating section which generates, in accordance with the detected proximity of the finger, an enlarged image by enlarging the image displayed in the screen with a prescribed enlarged display magnification, and a display control section which controls to display a local enlarged image corresponding to a part of the generated enlarged image in a superimposed manner over the image in a position in the screen vertically below the finger whose proximity has been detected.
