The smart watch with a control dial includes a watch body having a display on a top side and a control circuit inside the watch body, and a control dial electrically connected to the control circuit. The control dial has a portion of its circumference exposed from a lateral side of the watch body, and, when the control dial is turned, the control circuit detects the movement of the control dial and adjusts correspondingly the content shown on the display. The physical movement provided by the control dial effectively prevents the problem of operating the touch screen of the smart watch when the touch screen is stained.

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.
