Abstract:
An operation method of an optical touch device includes: emitting, by a light emitting unit, a light beam to illuminate an object; capturing, by an image sensing device, an image of the object reflecting the light beam; selecting all pixels in the image having a brightness greater than or equal to a brightness threshold; sorting the selected pixels along a first coordinate axis of the image, a second coordinate axis of the image or based a pixel brightness; selecting the top first predetermined ratio of pixels from the sorted pixels as an object image of the object; and calculating a gravity center of the object image according to positions of the top first predetermined ratio of pixels or according to the positions of the top first predetermined ratio of pixels with a weight of pixel brightness. An optical touch device is also provided.

Claim (Index 1):
An optical touch device, comprising:\n a light emitting unit configured to emit a light beam to illuminate an object; an image sensing device configured to capture an image of the object reflecting the light beam; and a processing circuit, electrically connected to the image sensing device, configured to obtain the image, select all pixels in the image having a brightness greater than or equal to a brightness threshold, sort the selected pixels based on the brightness of the selected pixels so as to sort the different distances of the object from the light emitting unit, select the top first predetermined ratio of the sorted pixels as an object image of the object, and calculate a gravity center of the object image, wherein the size of the object image is smaller than the size of the image of the object captured by the image sensing device.
