    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: Provided herein are a measurement device and an operation method thereof. The measurement device senses a distance variation between the measurement device and an object using a built-in proximity sensor and accordingly determines whether to turn on or turn off a track sensing module and an optical ranging module such that the measurement device provides intelligent selection to achieve energy saving without being interfered with by other sensors being turned on.
