INPUT DEVICE, STORAGE MEDIUM, INFORMATION INPUT METHOD, AND ELECTRONIC APPARATUS
First Claim
1. An optical input device having a display screen, a portion of the display screen being shielded from light by an operating member to implement input processing based on a plurality of input modes, the input device comprising:
- input detection means including a display unit configured to display predetermined input information, the input detection means detecting at least one of an area and brightness of a light-shielded portion formed on the display screen by the operating member by approaching the display unit; and
control means for providing display control of the display unit and input control on the basis of the at least one of an area and brightness detected by the input detection means,wherein the control means compares the detected at least one of an area and brightness with a predetermined threshold value to select a desired input mode from among the plurality of input modes.

Abstract
An optical input device has a display screen, a portion of the display screen being shielded from light by an operating member to implement input processing based on a plurality of input modes. The input device includes an input detection unit including a display unit that displays predetermined input information, and a control unit. The input detection unit detects an area and/or brightness of a light-shielded portion formed on the display screen by the operating member by approaching the display unit. The control unit provides display control of the display unit and input control on the basis of the detected area and/or brightness. The control unit compares the detected area and/or brightness with a predetermined threshold value to select a desired input mode from among the plurality of input modes.
