    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： 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.

    摘要： The present invention relates to a movement detection device for detecting a movement of an object in a space range. The movement detection device includes a light source, a light guiding element, at least two light sensing elements and a processing unit. The light sensing elements have an offset therebetween along a first direction such that the object, when moving in the space range, reflects the light from the light source sequentially to the light sensing elements through the light guiding element. The processing unit identifies the movement of the object along the first direction according to a sequence that the light sensing elements detect the light reflected by the object.

    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.

In the driving mode, the EDR is configured to perform high quality video recording using an image-capturing circuit. In the parking mode, the EDR is configured to periodically activate the image-capturing circuit for event detection and start to perform low quality video recording after detecting a specific event.
