Non-contact information input device
First Claim
1. A non-contact information input device comprising:
- an imaging section configured and arranged to capture an image of a prescribed imaging region including an object;
a shape detecting section configured and arranged to detect a shape of the object on the image obtained by the imaging section;
an operation mode selecting section configured and arranged to select a prescribed operation mode based on a detection result of the shape detecting section;
a distance detecting section configured and arranged to detect a distance between the imaging section and the object; and
a parameter adjusting section configured and arranged to adjust a value of at least one adjustable parameter used in the prescribed operation mode to obtain an adjusted value according to the distance detected by the distance detecting section.

Abstract
A non-contact information input device is provided that can easily and reliably use simple image processing to input information indicated by the shape of a user'"'"'s hand. The non-contact information input device is configured to detect a user'"'"'s hand using an imaging section, and to select an operation mode based on a shape of the hand. Then, a distance detecting section of the non-contact information input device is configured to detect a distance from the hand to the imaging section and adjust a parameter used in the operation mode in response to the distance if the parameter is adjustable. Thus, the image processing load is reduced and the parameter is easily and reliably adjusted by adjusting the parameter in the selected operation mode based on the distance detected by the distance detecting section.
