| 20110134078 | Distance-measuring device, 3D image-sensing device, and optical touch system - 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. | 06-09-2011 |
| 20110157579 | Distance-measuring device with increased signal-to-noise ratio and method thereof - A method of increasing signal-to-noise ratio of a distance-measuring device includes a light-emitting component emitting a detecting light to a measured object during an emitting period for generating a reflected light, a delay period after the light-emitting component emitting the detecting light, a light-sensing component sensing the energy of the reflected light to generate a light-sensing signal, and obtaining a measured distance between the distance-measuring device and the measured object according to the energy of the detecting light and the light-sensing signal. Since the measured distance is longer than a predetermined shortest measured distance, the method can accordingly calculate a proper delay period for ensuring that the reflected light reaches the light-sensing component after the delay period. In this way, the light-sensing component does not sense the background light during the delay period, so that the signal-to-noise ratio of the light-sensing signal is improved. | 06-30-2011 |
