摘要： A calibrating method of calibrating a measured distance of a measured object measured by a distance-measuring device according to an ambient temperature includes providing a temperature sensor for measuring the ambient temperature of the distance-measuring device, calculating a calibrated imaging location of the measured object according to the ambient temperature and an imaging location of the measured object, and calibrating the measured distance according to the calibrated imaging location. In this way, when the distance-measuring device measures the measured object, the error due to the variation of the ambient temperature is avoided according to the calibrating method.

摘要： A shooting parameter adjustment method for face detection includes (A) acquiring an image; (B) dividing the image into a plurality of blocks, and calculating a brightness value of each of the blocks; (C) selecting at least one of the plurality of blocks, and adjusting a shooting parameter according to the brightness value of the selected block; and (D) acquiring another image according to the shooting parameter, and performing a face detection procedure with the another image. The shooting parameter adjustment method can automatically adjust a shooting parameter of an image capturing device according to brightness of different blocks in an image. Therefore, by using this method, the brightness of a face, no matter being too high or too low, can be adjusted to a value suitable for face detection, so as to improve the accuracy of the face detection procedure.

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 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.
