摘要： Optical touch display system includes a light source, a reflector, an image sensor, and a processing device. The light source emits light to at least one object directly and emits light to the at least one object via the reflector at the same time. Then the image sensor receives light reflected from the at least one object directly and light reflected via the reflector simultaneously to form a set of imaging objects which have similar color parameters on an image. Then the processing device produces a set of still image parameters of the image objects such as gravity centers and border boundaries. Based on the still image parameters, the processing device determines the coordinates of the least one object on the optical touch display.

摘要： A system for integrating heart rate measurement and identity recognition is provided. The system includes a storage unit, an image sensor, an identity recognition unit and a frequency extractor. The storage unit stores a user information database. The image sensor captures a plurality of skin images of a user during a time period. The identity recognition unit receives a physiological feature from the user and recognizes the user by comparing the physiological feature with the user information database in the storage unit. The frequency extractor obtains a frequency signal by extracting a motion signal from the skin images according to the brightness change of the different color lights in the skin images during a time period. The frequency signal represents a frequency in a specific frequency interval, and it represents heart rate information of the user. A method for use in the above-mentioned system is also disclosed.

摘要： A distance measuring system includes a light source module, an image capturing device and a processing module. The light source module transmits a light beam having a speckle pattern to a first flat surface and a second flat surface, and an object. The image capturing device captures the image of the speckle pattern shown on the first and second flat surfaces, and captures the image of the speckle pattern shown on a surface of the object to produce a first reference image information, a second reference image information, and an object image information. The processing module calculates a displacement vector of the speckle pattern according to the first and second reference image information. The processing module calculates the relative distance between the object and the first flat surface or the second flat surface according to the position of the speckle pattern on the object image information and the displacement vector.
