IMAGE PROCESSING METHOD FOR OPTICAL TOUCH SYSTEM |
摘要 |
An image processing method for an optical touch system includes the steps of obtaining an image and generating a light distribution curve pattern from the image, selecting a target signal of the light distribution curve pattern in accordance with light intensity information of the light distribution curve pattern, determining at least one rising slope and at least one falling slope of the target signal, and selecting the target signal as an object signal when the absolute values of the at least one rising slope and at least one falling slope are greater than a threshold. |
