摘要： A first image sensor captures a first image of a panel of a touch screen. The first image includes a first object, a second object, a first set of reference marks, a second set of reference marks, and a first boundary mark. The touch screen establishes relationships of relative positions among the first image sensor, the first object, the second object, and the reference marks according to positions of the first object, the second object, and the reference marks in the first image. And the touch screen calculates a relative position between the first image sensor and the panel according to the relationships of relative positions among the first image sensor, the first object, the second object, and the reference marks and relative positions among the first object, the second object, and the panel.

摘要： An optical sensing system includes a sensing area, a reflective mirror, a first image-sensing device, a second image-sensing device, and a processing circuit. The sensing area is an area in which a plurality of pointing objects may execute touch operation. The reflective mirror generates a mirror image of the sensing area. The first image-sensing device and the second image-sensing device respectively capture images including all or part of the pointing objects in the sensing area, and all or part of the pointing objects in the reflective mirror. The processing circuit generates candidate coordinates according to the images captured by the first and the second image-sensing devices, and obtains the locations of the pointing objects from the candidate coordinates by means of the symmetric relationship between the point objects and the corresponding mirror images with respect to the reflective mirror. In this way, the optical sensing system can perform multi-touch operation.

摘要： In a sensing system and a method for obtaining a location of a pointer, the sensing system includes a sensing area, a reflective mirror, a first image sensor and a second image sensor. The reflective mirror is configured for generating a mirror image of the sensing area. The sensing system utilizes the above two image sensors to sense the pointer disposed in the sensing area and a mirror image of the pointer for obtaining two coordinate values. And then the sensing system endues each of the two coordinate values with a weighting factor for calculating the location of the pointer.
