摘要： A detection device includes an image capture element, a control signal generator, and a processor. The image capture element is used for capturing an optical signal, and outputting an image signal. The control signal generator is used for generating a control signal. The processor selectively converts the image signal into an object feature or an image feature in response to the control signal. Such a detection device can appropriately convert an operation mode, so as to have both efficacies of reducing the amount of transferred data and processing complex image data.

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 includes a light-emitting/sensing controlling circuit, a light-emitting component, a light-sensing group, a background-calculating circuit, a frequency-adjusting circuit, and a distance-calculating circuit. The light-emitting component emits a detecting light to a measured object. The light-emitting/sensing controlling circuit controls the light-sensing group receiving and accumulating the energy of a reflective light generated by the measured object reflecting the detecting light, so that the distance-calculating circuit can calculate a measured distance between the measured object and the distance-measuring device according the accumulated energy of the light-sensing group. In addition, the distance-measuring device calculates the energy accumulated by the light-sensing group sensing the background light per unit time, by means of the background-calculating circuit. In this way, the effect of the background light is reduced so that the distance-measuring device can more correctly calculate the measured distance.

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.
