Abstract

An object of the present invention is to provide a portable electronic device capable of suppressing incorrect inputs. A control unit of a cellular telephone device detects a distance between an object in proximity to a display unit and a display surface of the display unit, and a position on the display unit corresponding to the distance, causes the display unit to display a keyboard configured with a plurality of images displaying keys, and in response to a contact detecting unit having detected contact of an object to the display unit, the control unit accepts an input of a key corresponding to the image. The control unit causes the display unit to display images, which are displayed within a predetermined range from the position detected on the display unit, in an enlarged manner.

Claims

1. A portable electronic device, comprising:

a display unit;

a contact detecting unit that detects contact of an object to the display unit;

a proximity detecting unit that detects proximity of the object in proximity to a display surface of the display unit; and

a control unit that causes the display unit to display images, which are displayed within a predetermined range of the display surface facing the object, in an enlarged manner, in a case in which the proximity detecting unit detects proximity of the object to the display surface.

2. The portable electronic device according to claim 1,

wherein the proximity detecting unit detects a distance between the object in proximity to the display unit and the display surface of the display unit, and a position on the display unit corresponding to the distance, and

wherein the control unit causes the display unit to display a keyboard configured with a plurality of images displaying keys, accepts an input of the key corresponding to the image in response to the contact detecting unit having detected contact of the object to the image, and causes the display unit to display the images, which are displayed within a predetermined range from the position on the display unit detected by the proximity detecting unit, in an enlarged manner.

3. The portable electronic device according to claim 2, wherein, in a case in which the distance detected by the proximity detecting unit is shorter than a first distance, the control unit causes the display unit to display the images, which are displayed within the predetermined range, in an enlarged manner.

4. The portable electronic device according to claim 1,

wherein the control unit causes the display unit to display the images, which are displayed within the predetermined range, in an enlarged and semi-transmissive manner.

5. The portable electronic device according to claim 3,

wherein, in a case in which the distance detected by the proximity detecting unit is shorter than a second distance that is shorter than the first distance, the control unit performs control such that the images, which are displayed in an enlarged manner on the display unit, are displayed without any changes in accordance with the position.

6. The portable electronic device according to claim 5,

wherein, in a case in which the distance detected by the proximity detecting unit is shorter than the second distance, the control unit performs control such that the images, which are displayed in an enlarged manner on the display unit, are displayed in a highlighted and statical manner.

7. The portable electronic device according to claim 5,

wherein, in a case in which the distance detected by the proximity detecting unit is shorter than a third distance that is shorter than the second distance, the control unit changes a display manner of the image corresponding to the position on the display unit detected by the proximity detecting unit, and

accepts an input of the key corresponding to the image whose display manner was changed in response to the contact detecting unit having detected contact of the object to the display unit.
