    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: A power-saving sensing module includes a light source, a first and a second sensor, a first and a second detection unit, and a controller. The first sensor detects a touch of an external object to generate a first sensing signal corresponding to the touch. The first detection unit generates a touch signal corresponding to the first sensing signal.The second sensor senses a second sensing signal corresponding to the external object in response to the light ray. When the touch signal is greater than a touch threshold value, the second detection unit outputs a displacement signal corresponding to the second sensing signal. The controller outputs a control signal in response to the touch signal of the first detection unit and the touch threshold value, so that the second detection unit operates at a dormant state or a sensing state in response to the control signal.
