Abstract: There is provided a displacement detection device including a light source, an image sensor and a processing unit. The light source provides light to a finger with a light source parameter. The image sensor receives reflected light from the finger, outputs valid images when the light source is being turned on and outputs dark images when the light source is being turned off. The processing unit determines a contact status according to one of the dark images and one of the valid images, and calculates a displacement according to two of the valid images to accordingly adjust the light source parameter.

Abstract: An object navigating apparatus, which comprises: a sensing apparatus, for sensing an object; and a control unit, for computing at least one displacement that the object is relative to the sensing apparatus. The control unit increases the sensing resolution if the control unit detects the displacement is larger than a first predetermined value for continuous N times, or if the control unit detects the displacement is larger than the first predetermined time for at least N times in a first sensing time interval. The N is a positive integer larger or equals to 2.

Abstract: There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.

Abstract: A gesture recognition method with improved background suppression includes the following steps. First, a plurality of images are sequentially captured. Next, a position of at least one object in each of the images is calculated to respectively obtain a moving vector of the object at different times. Then, an average brightness of the object in each of the images is calculated. Finally, magnitudes of the moving vectors of the object at different times are respectively adjusted according to the average brightness of the object in each of the images. There is further provided a gesture recognition apparatus using the method mentioned above.
