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.

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.

Optical detection device and related turntable watch

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 captures reflection of a light emitting to the structure to detect 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.
