Abstract

The present invention relates to an optical positioning system and a method for calculating the movement value of the optical positioning system, which is composed of: an image sensor for detecting light reflected from the surface of the workbench and generating an image signal; a maximum search window can be a change circuit for inputting at least one of an image signal and a shift value to change the size of the maximum search window; and a shift value calculation circuit for calculating the shift value of the image signal using the size-changed maximum search window . Therefore, by calculating the movement value according to at least one of a luminous flux and a movement speed, changing at least one maximum search window and a sampling rate can obtain an accurate movement value.

Description

technical field [0001] The present invention relates to an optical positioning system, in particular to an optical positioning system capable of adaptively changing the maximum search window and / or sampling rate according to the luminous flux and moving speed of incident light and a method for calculating its moving value. [0002] This application claims priority to Korean Patent Application No. 2002-72821 filed on November 21, 2002 and Korean Patent No. 2003-79623 filed on November 11, 2003, the disclosures of which are hereby incorporated by reference in their entirety. Background technique [0003] like figure 1 As shown, a common optical positioning system is composed of a light source 8, a lens 5, and an image sensor of the sensor circuit 3 (not shown in the figure). [0004] exist figure 1 Among them, the number 2 represents the table surface, and the numbers 4, 6, and 7 represent the light. [0005] exist figure 1 In the optical positioning system shown, light 7 ...
