INPUT DEVICE FOR GENERATING AN INPUT INSTRUCTION BY A CAPTURED KEYBOARD IMAGE AND RELATED METHOD THEREOF
First Claim
1. An input device for generating an input instruction by captured images, comprising:
- a first image capturing module disposed around a keyboard for capturing a first object image of an object and a first key image of a key on the keyboard;
a second image capturing module disposed around the keyboard for capturing a second object image of the object and a second key image of the key on the keyboard; and
a logic control unit for calculating a first distance according to the first object image and the first key image and a second distance according to the second object image and the second key image, and further for generating the input instruction when determining that the first distance and the second distance are respectively smaller than a first threshold value and a second threshold value.

Abstract
An input device for generating an input instruction by captured images is disclosed. The input device includes a first image capturing module, a second image capturing module and a logic control unit. The first image capturing module and the second image capturing module are disposed around a keyboard for respectively capturing a first object image and a second object image of an object and for respectively capturing a first key image and a second key image of a key on the keyboard. The logic control unit is used for calculating a first distance according to the first object image and the first key image and a second distance according to the second object image and the second key image, and for generating the input instruction when the first distance and the second distance are smaller than a first threshold value and a second threshold value, respectively.
