Title:
SYSTEM FOR INFORMATION INPUT INTO COMPUTER AND METHOD FOR CALCULATING COORDINATES OF INPUT INFORMATION BY USING INFORMATION INPUT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/250238
Kind Code:
A1
Abstract:
The present invention relates to an information input system for acquiring an image of a display area in which an image of a computer is displayed, and calculating coordinates of an information input in the display area and processing as input information, and comprises: a plurality of image capturing apparatuses that divide and photograph a display area; and an image processing module that analyzes images captured by the image capturing apparatuses and extracts, from the captured images, a signal relating to an information input. Each of the image capturing apparatuses is arranged so as to photograph one divided display area of the display area, and has a unique photographing area of the corresponding image capturing apparatus and an overlapping photographing area overlapping with the other image capturing apparatus. The image processing module: with respect to an information input in the unique photographing area of each of the image capturing apparatuses, discriminates coordinates of the information input according to coordinate values of the corresponding image capturing apparatus in the display area; with respect to an information input in the overlapping photographing area, discriminates coordinates of the information input according to coordinates of each of the image capturing apparatuses for the corresponding overlapping photographing area in the display area; and processes the discriminated coordinates according to a blending function and calculates as coordinates of an information input.
