    Abstract: There is provided a displacement detection device including an image sensor, a light source, a light control unit and a processing unit. The image sensor captures image frames at a sampling frequency. The light source provides, in a speed mode, light for the image sensor in capturing the image frames. The light control unit controls the light source with the speed mode to turn on at a lighting frequency or to turn off serially. The processing unit calculates a displacement according to the image frames captured when the light source turns on to be served as an estimated displacement for an interval during which the light source turns off. There is further provided an operating method of a displacement detection device.

    Abstract: A distance measuring system includes a light source module, an image capturing device and a processing module. The light source module transmits a light beam having a speckle pattern to a first flat surface and a second flat surface, and an object. The image capturing device captures the image of the speckle pattern shown on the first and second flat surfaces, and captures the image of the speckle pattern shown on a surface of the object to produce first reference image information, second reference image information, and object image information. The processing module calculates a displacement vector of the speckle pattern according to the first and second reference image information. The processing module calculates the relative distance between the object and the first flat surface or the second flat surface according to the position of the speckle pattern on the object image information and the displacement vector.

    Abstract: A power-saving sensing module includes a light source, first and second sensors, first and second detection units, and a controller. The first sensor detects a first image corresponding to a working plane in response to at least a part of the light ray from the light source to generate a first sensing signal. The first detection unit generates a displacement signal in response to the first sensing signal. The second sensor detects a second image corresponding to an object in response to at least a part of light ray to generate a second sensing signal. The second detection unit generates a touch signal corresponding to the object in response to the second sensing signal. The controller outputs a control signal in response to the touch signal. The first detection unit operates at a dormant state or a sensing state in response to the control signal.
