    摘要： Distance-measuring system with correction function includes calibrating object, transflective plate, and distance-measuring device. Distance-measuring device has a first known distance and a second known distance respectively between calibrating object and transflective plate. Transflective plate is disposed between calibrating object and distance-measuring device. Distance-measuring device includes light emitting device for emitting a detecting light with lighting-error angle, image sensor with sensing-error angle, and parameter calculating circuit. First part of detecting light passes transflective plate and is reflected by calibrating object and becomes first reflecting light emitting to first imaging location of image sensor while second part of detecting light is reflected by transflective plate and becomes second reflecting light emitting to second imaging location of image sensor. Parameter-calculating circuit calculates lighting-error angle and sensing-error angle according to first and second known distances, and first and second imaging locations.

    摘要： A distance-measuring device is utilized for measuring a measured distance between a measured object and the distance-measuring device. The distance-measuring device reduces the effect of a background light and a flicking light by removing the part corresponding to the background light and the flicking light from light-sensed signals generated by an image sensor of the distance-measuring device. In addition, the distance-measuring device calculates a calibrating parameter for calibrating an assemble-error angle of the distance-measuring device, according to an imaging location of a reflective light obtained by measuring a calibrating object with a predetermined distance. In this way, the distance-measuring device can correctly calculate out the measured distance.

    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.
