Abstract: An imaging device including a condenser lens and an image sensor is provided. The image sensor is configured to sense light penetrating the condenser lens and includes a pixel matrix, an opaque layer, a plurality of microlenses and an infrared filter layer. The pixel matrix includes a plurality of infrared pixels, a plurality of first pixels and a plurality of second pixels. The opaque layer covers upon a first region of the first pixels and a second region of the second pixels, wherein the first region and the second region are mirror-symmetrically arranged in a first direction. The plurality of microlenses is arranged upon the pixel matrix. The infrared filter layer covers upon the infrared pixels.

Abstract: Provided herein are a sensing device and a control method thereof. The sensing device comprises a control unit, at least one first sensor and at least one fake sensor. The first sensor configured for detecting a touch event and generating a first sensing signal corresponding to an environmental change and an applied touch event, and sending the first sensing signal to the control unit. The fake sensor configured for generating a second sensing signal corresponding to the environmental change, and sending the second sensing signal to the control unit, wherein the control unit compensates the first sensing signal for the environmental change by using the second sensing signal and generates a compensated signal corresponding to the applied touch event. Accordingly, the present invention achieves the result of removing the influence of environmental changes for the sensing device.

Abstract: A treadmill and a control method for controlling the treadmill belt thereof are provided. The treadmill includes a treadmill belt, a first sensor, an image sensor, and a controller. The first sensor retrieves a light pattern or the image sensor measures the characteristic properties of the image of the user so as to control the treadmill belt. The light pattern can be generated by a signal member, which can be disposed on a side or both sides of the treadmill belt.
