Abstract: There is provided a robot including a first light source, a second light source, an image sensor and a processor. The processor is used to calculate an image quality of an image frame captured by the image sensor when the second light source is being turned on. The processor then determines whether to switch the second light source back to the first light source according to the image quality to accordingly identify the material of an operation surface.

Abstract: An optical tracking device includes an optical detection module and a target component. The optical detection module includes an optical receiver. The target component includes a light penetrating body with at least one mark and movably disposed adjacent to the optical detection module. The target component allows an illumination beam penetrating into the light penetrating body, so that the optical detection module acquires a detection image containing a pattern of the mark for tracking a relative movement between the target component and the optical detection module.

Abstract: An electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit emits light to the structure, captures reflected light from the structure to sense/receive an image from the surface of the structure, detects displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.

Abstract: An optical detection device capable of detecting a pointer position of a turntable watch includes an optical receiver and a processor. The optical receiver is disposed inside the turntable watch and adapted to receive an optical reflecting signal. The processor is electrically connected to the optical receiver and adapted to compare a physical quantity of the optical reflecting signal with a predefined condition for determining whether a pointer of the turntable watch is located above the optical receiver. The optical detection device further includes an optical emitter electrically connected to the processor and adapted to emit an optical detecting signal. The optical detecting signal is projected onto the pointer to generate the optical reflecting signal.

Abstract: An optical detection device of detecting whether a target object has different surface treatment features includes an image sensor and an operation processor. The image sensor is adapted to acquire a detection image containing the target object. The operation processor is electrically connected to the image sensor, and adapted to compute variation of an image shading parameter of the detection image so as to determine whether a boundary of the surface treatment features are detected by the image sensor in accordance with the variation of the image shading parameter.
