Abstract: An amending circuit includes a comparing unit, a predetermined voltage generating unit, a roller switch, alight emitting unit switch and a controlling unit. A pin of the mouse and the predetermined voltage generating unit are respectively connected to two input terminals of the comparing unit. The controlling unit is coupled to the light emitting unit switch and the roller switch. The controlling unit switches to a motion detecting mode to drive a current of the current source to flow toward a second pin via the first pin and a light emitting unit of the mouse. The controlling unit further switches to a roller detecting mode to set a pressure of the first pin lower than a predetermined voltage of the predetermined voltage generating unit while the roller is grounded or to set the first pin higher than the predetermined voltage while the roller is not grounded.

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.
