Abstract: An optical processing apparatus and a light source luminance adjustment method adapted to detect a rotational displacement and a pressing state are provided. The optical processing apparatus includes a light source unit, a processing unit, and an image sensing unit, wherein the processing unit is electrically connected to the light source unit and the image sensing unit. The light source unit provides a beam of light. The processing unit defines a frame rate, defines a plurality of time instants within a time interval, and sets the light source unit to a luminance value at each of the time instants. A length of the time interval is shorter than the reciprocal of the frame rate. The luminance values are different and are within a range. The image sensing unit captures an image by an exposure time length at each of the time instants, wherein the exposure time lengths are the same.

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 detecting device includes a multi-axis instruction outputting mechanism and an optical detecting module, and shift of the multi-axis instruction outputting mechanism is determined accordingly. An actuating component of the multi-axis instruction outputting mechanism is moved in reciprocation at a first operating direction to output an instruction. The optical detecting module is detachably disposed to the actuating component. An interval between the optical detecting module and the actuating component is varied according to a relative movement between the optical detecting module and the actuating component at a second operating direction, and the actuating component can be shifted between different gears. The optical detecting module determines the interval and gearshift according to variation of a reflecting signal actuated by the actuating component, and utilizes the reflecting signal to acquire a movement of a feature point detachably disposed on the actuating component along the first operating direction to interpret the instruction.
