Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] refer to Figure 1 ~ Figure 3 , an optical imaging system for simulating a touch screen, including an optical imaging component, an image preprocessing module, a checksum calculation module on the warning line, a fingertip position acquisition module, a mechanism for judging the operation type, and an execution operation module and next sampling Time sampling start line number fallback mechanism module;

[0046] The optical imaging component is composed of a fixing clip that can be clamped at the position of the camera on the screen of the notebook computer, and an optical structural component that can be combined with the fixing clip in a threaded way or a magnetic way;

[0047] In the image preprocessing module, the CPU calls the camera picture at regular intervals, that is, performs a sampling; the information of the corresponding color corresponding to the ...

Abstract

The invention discloses an optical imaging system for simulating a touch screen. The optical imaging system comprises an optical imaging assembly, an image preprocessing module, a checksum calculationmodule on a warning line, a fingertip position collection module, an operation type judgment mechanism and operation execution module and a sampling start line number fallback mechanism module duringnext sampling, the optical imaging assembly is composed of a fixing clamp and an optical structure assembly. In the image preprocessing module, a CPU (Central Processing Unit) calls a camera pictureonce every a certain time; representing the information of the corresponding color corresponding to the position of the pixel point, which originally needs to be represented by a 24-bit storage space,by one bit; in the operation type judging mechanism and the operation executing module, when the row number of the array is equal to 3, it is indicated that the array with three rows and two columnsis full, the operation type judging mechanism is started to be executed, and elements in the array with three rows and two columns are judged. Under the condition that a touch screen is not used, thetouch effect can be achieved for the display screen.

Description

technical field [0001] The invention relates to the field of optical imaging system and image processing, in particular to an optical imaging system for simulating a touch screen. Background technique [0002] With the rapid development of the times, more and more electronic devices have entered thousands of households and entered the streets and alleys, and the display screen, as a medium for human-machine interaction, plays a pivotal role in people's daily life. No matter in the car, in the shopping mall, in the classroom, or even in the streets and alleys, the display screen can be seen everywhere. Outdoor display screens as large as hundreds of square meters, as small as smart watches for mobile phones, it can be said that it is precisely because of the existence of display screens that people can truly enjoy the comfort and convenience brought by the development of technology to people's lives. [0003] But there are two concepts that are easy to confuse, that is, the ...
