摘要： In a sensing system and a method for obtaining a position of a pointer, the sensing system includes a sensing area, a reflective mirror, an image sensor and a processing circuit. The reflective mirror is configured for generating a mirror image of a pointer when the pointer approaches the sensing area. The image sensor is configured for sensing the pointer and the mirror image thereof when the pointer approaches the sensing area. When the pointer approaches the sensing area, the processing circuit calculates a coordinate value of the pointer according to an image sensed by the image sensor and a predetermined size of the pointer. The pointer forms an imaginary orthographic projection in the sensing area, the processing circuit regards the imaginary orthographic projection as a round projection, and a radius of the round projection is the predetermined size.

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.

摘要： When an object touches a touch panel, a projection light source projects a predetermined image including image information and forms an object image having the image information on a surface of the object. An image sensor captures a reflection image including the object image. Then, an angle is calculated according to an image location of the object in the reflection image and a relative position of predetermined axis, and a distance between the object and the image sensor is calculated by comparing the predetermined image with the location, size and/or phase of the image information of the reflection image so as to determine a coordinate of the object on the touch panel according to the angle and the distance.

摘要： An image processing method is applicable to a pointing device. The pointing device generates a displacement signal by moving relative to a working surface and detecting an image of a part of the working surface. The method includes the following steps. A first original image is obtained. The first original image is uniformly divided into a plurality of blocks. A block brightness value of each block is adjusted. A complexity signal representing a plurality of gradient values of each block is generated. The blocks are sequentially adjusted according to the adjusted block brightness value and complexity signal, so as to generate a first adjusted image corresponding to the first original image.
