Optical imaging device and imaging processing method for optical imaging device

Abstract

An optical imaging device includes a display panel whereon a coordinate detecting area is formed, at least one light source disposed on a corner of the display panel for emitting light to illuminate an object, a first image capturing module disposed on a corner of the display panel for capturing image information of the object, a second image capturing module disposed on another corner of the display panel for capturing image information of the object, and a control module coupled to the first image capturing module and the second image capturing module for determining whether to calculate a coordinate value of the object according to whether the first image capturing module and the second image capturing module capture the image information of the object simultaneously.

Description

technical field [0001] The invention relates to an optical image touch device and a touch image processing method, in particular to an optical image touch device and a touch image processing method without using a reflective frame. Background technique [0002] In today's various consumer electronic product markets, portable electronic products such as personal digital assistants, mobile phones, and mobile phones have widely used touch devices as interface tools for data communication. Since the current design of electronic products is light, thin, short, and small, there is not enough space on the product to accommodate traditional input devices such as keyboards and mice, especially driven by the demand for tablet computers that emphasize humanized design. Displays with touch devices have gradually become one of the key components of various electronic products. However, there are many touch technologies developed today, such as resistive, capacitive, ultrasonic, infrared...

Problems solved by technology

However, since the reflective frame needs to be coplanar with the sensor, it is difficult to assemble and increases the manufacturing cost; however, an optical image touch device without a reflective frame will be caused by interference sources outside the coordinate detection area. The touch points are difficult to judge due to external interference, so how to design an optical image touch device that can effectively reduce the difficulty and cost of assembly and improve the judgment accuracy of touch points at the same time is the current touch technology. One of the important issues to be worked on
