COORDINATE INPUT DEVICE AND DISPLAY DEVICE PROVIDED WITH SAME
First Claim
1. A coordinate input device, comprising:
- a touch panel configured to be disposed on a display panel, the touch panel detecting contact made by an instruction input member in a detection area on the touch panel;
an acquisition unit that acquires image data of a user performing input on said touch panel;
an identification unit that analyzes said image data from the acquisition unit to identify a reference input location in said detection area on the touch panel;
a setting unit that sets a predicted input area where input by said instruction input member may occur within said detection area on the touch panel, said predicted input area being set in accordance with said reference input location identified by said identification unit and in accordance with information representing a positional relationship between said instruction input member and a hand supporting said instruction input member; and
an output unit that identifies and outputs an input location on said predicted input area in accordance with a detection result on said touch panel.

Abstract
Provided is a technology in which even if input is performed in a state where a hand supporting a pen or the like is placed upon a touch panel, erroneous input from the hand can be prevented. A touch panel control unit acquires from a control unit, image data in which a user who will perform input in a detection area of a touch panel was imaged. The touch panel control unit analyzes the image data, identifies an instruction input unit and a hand of a user supporting the input instruction unit, and identifies a reference input location in the detection area. On the basis of a positional relationship of the instruction input unit and the hand of the user, a predicted input area within the detection area, in which input by the input instruction unit may occur, is then set. On the basis of a detection result obtained from the touch panel, the touch panel control unit identifies and outputs an input location in the predicted input area.
