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： An optical sensor includes an image sensor, a proximity sensor and a visible light sensor. The image sensor includes a first pixel and a second pixel. The first pixel is coated with a first optical film for blocking light whose wavelength is outside a first predetermined range and a second optical film for blocking light whose wavelength is outside a second predetermined range. The proximity sensor generates an IR signal according to a first exposure value. The visible light sensing unit generates a visible light signal according to the difference between the first exposure and a second exposure value or according to a ratio of the first exposure value to the second exposure value. The first exposure value represents an incident light quantity which is absorbed by the first pixel. The second exposure value represents an incident light quantity which is absorbed by the second pixel.
