    Abstract: A wearable device includes: a light source, a sensor and a processor. The light source selectively operates in an illuminating mode or a non-illuminating mode, and generates an auxiliary light passing through a physical body in the illuminating mode. The sensor captures detecting images from the physical body, wherein the detecting images include at least one illuminating image captured while the light source is in the illuminating mode, at least one pre-illuminating image captured before the illuminating image is captured while the light source is in the non-illuminating mode, and at least one post-illuminating image captured after the illuminating image is captured while the light source is in the non-illuminating mode. The processor generates physiological information of the physical body according to the illuminating image, the pre-illuminating image and the post-illuminating image.

    Abstract: An optical mouse apparatus includes a light source circuit, a sensing circuit, and a processing circuit. The light source circuit is used for generating and emitting a light signal onto a surface so as to generate a light reflected signal. The sensing circuit is used for estimating an image offset of the optical mouse apparatus. The processing circuit is coupled to the light source circuit and the sensing circuit and used for generating and outputting a control signal to a terminal according to the image offset outputted by the sensing circuit. The sensing circuit is further used for detecting at least one of a moving speed or an offset direction of the image offset of the optical mouse apparatus, so as to dynamically determine whether to compress data of the image offset outputted to the processing circuit, for reducing data amount read by the processing circuit.
