    摘要: A touch system and an optical touch system with a power-saving mechanism are presented. The touch system includes a sensing module and a processing module electrically connected to the sensing module; the optical touch system includes an optical sensing module and a processing module electrically connected to the optical sensing module. The processing module modulates a working frequency and/or a working voltage of the processing module according to a touch point count on a touch region, a preset function of the processing module, and/or an imaging count detected by the optical sensing module, so as to decrease a power consumption of the processing module. An electronic device equipped with such system may not only dynamically adjust the working frequency and/or the working voltage of the processing module, but also can determine a working frequency and/or a working voltage satisfying a report rate through an input of the system.

    摘要: An optical touch system, an apparatus and a method for calculating the position of an object are provided. The apparatus includes an image sensor and a processing circuit. The processing circuit selects at least one dot from a curve segment of a brightness distribution profile obtained from a background image, wherein the curve segment corresponds to an imaging range of an object. And the processing circuit regards the column pixel brightness value corresponding to the dot as a brightness reference value. Afterwards, the processing circuit calculates brightness difference between the brightness reference value and the column pixel brightness values corresponding to the dots of a curve segment of a brightness distribution profile obtained from a sensed image, so as to further calculate a gravity of the imaging range. After that, the processing circuit regards the gravity as a representative position of the object in the sensed image.

    摘要: An apparatus and a method for acquiring object image of a pointer are provided. The apparatus is suitable for an optical touch system and is used for acquiring an object image of a pointer when the pointer interacts with a touch surface of the optical touch system. The apparatus includes an image sensor and a processing circuit. The image sensor is used for acquiring an image of the touch surface. When the pointer approaches the touch surface, the processing circuit compares at least a part of the information of a sensed image with a threshold value, so as to determine a comparison range. Then, the processing circuit determines another threshold value according to the image information in the comparison range. Afterwards, the processing circuit compares the image information in the comparison range with the aforementioned another threshold value, so as to acquire an object image of the pointer.

    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.
