    Abstract: A motion detecting device and the method for dynamically adjusting image sensing area is disclosed. The motion detecting device includes a light source, an image capture unit and a processing unit. The image capture unit is used to capture reference image according to fixed sampling period. The processing unit is used to calculate exposure reference value of the light source and image characteristic value of reference image. The processing unit according to the exposure reference value and the image characteristic value to determine whether the surface is in first rough coefficient range or second rough coefficient range. If rough coefficient of the surface is in the first rough coefficient range, the processing unit defines first search radius or second search radius to increase or decrease the image sensing area. Otherwise, the processing unit defines third search radius or fourth search radius to increase or decrease the image sensing area.

    Abstract: The present invention discloses a displacement detecting device including a displacement sensing module, an input module, a distance sensing module, and a processing module, and a power saving method thereof. The processing module is electrically connected to each module. The input module is used to supply non-contact operation. The distance sensing module is used to detect the distance between a body and the displacement detecting device, and then produces a sensing value. The processing module selectively control the displacement sensing module and the input module to be turned on or turned off according to the sensing result of the distance sensing module. The displacement detecting device turns on the displacement sensing module when the sensing value is less than a first default value, and turns on the input module and turns off the displacement sensing module when the sensing value is greater than a second default value.
