摘要: A background image updating method is adapted to a touch screen including a first and a second image modules. A first and a second images are captured by the first and the second image modules as a first and a second background images, respectively. (a) Whether an absolute value of a brightness difference between a third image captured by the first image module and the first background image is greater than a predetermine value is compared. (b) If the result of the step(a) is yes, whether an absolute value of a brightness difference between a fourth image captured by the second image module and the second background image is greater than another predetermine value is compared. (c) If the result of the step(b) is yes, a fifth and a sixth images are captured by the first and the second image modules as the first and the second background images, respectively.

摘要: The invention provides an optical touch display device. The optical touch display device comprises a display module, a first image capturing module, a second image capturing module and a processing module. The display module generates N touch points according to a touch gesture, the touch gesture has a specific moving model, and N is a positive integer. The first image capturing module retrieves a first image relating to N touch points. The second image capturing module retrieves a second image relating to N touch points. The processing module determines correspondingly a specific touch chord of N touch points according to the first image and the second image, and determines correspondingly a specific function of the touch gesture according to the specific touch chord and the specific moving mode.
