According to the invention, starting at the start of the detecting interval, successive first images at a first view and successive second images at a second view relative to the N objects and a background of the perimeter of the coordinate input region are captured and buffered. The apparatus and method according to the invention judges the number of the N objects and calculates the positions of the N objects on the coordinate input region at the detecting interval in accordance with the buffered successive first images and the buffered successive second images."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image-based coordinate input apparatus and method utilizing buffered images","description":"The invention provides an image-based coordinate input apparatus and method for detecting positions of N objects on a coordinate input region at a detecting interval where N equals to 1 or 2.
