Patent Images
1. A data input apparatus, comprising:
- an image input module to obtain an input image representing at least one selectable input; and
a controller to control a binarizing of at least one respective digital image of at least one respective input from the obtained input image, and to determine selection by a user of the at least one respective selectable input based on a comparison of a corresponding binarized image of the at least one respective digital image with a corresponding previously stored binarized image, wherein binarized images are converted grayscale digital images that have been converted from respective grayscale images to binary images having only a maximum scale and a minimum scale to represent an intensity of each pixel.

Abstract
A data input apparatus, medium, and method detecting a selected data key input. The data input apparatus may include an image output module, an image input module, and a control module, with the image output module generating an input image having a predetermined number of input keys for the input of data. The image input module may capture the generated input image, and the control module may then binarize the captured images of the respective input keys, e.g., using a predetermined threshold value. Accordingly, the proper selection of input keys can be determined by comparing the binarized images with previously stored binarized images.
