Abstract: An optical navigation device has a light-emitting unit, an optical navigation chip and a cover. The light-emitting unit provides a light to a surface of a displacement generating unit. The optical navigation chip has a sensing array, but excludes any optical lens for focusing a reflected light. The sensing array disposed opposite to the surface of the displacement generating unit receives the reflected light which the light provided by the light-emitting unit is reflected from the surface of the displacement generating unit. The cover has a first surface and a second surface, and an angle is formed between the cover and the optical navigation chip, to prevent another reflected light from the surface of the first surface of the cover from entering the sensing array. Particularly, the angle formed between the cover and the optical navigation chip is from 10 degrees to 15 degrees.

Abstract: An electronic device includes a case, a manipulation ring disposed on the case, a rotational unit, a waterproof member, and an optical tracking system (OTS) sensor. The case has a first chamber and a second chamber arranged outside the first chamber. The case has a thru-hole arranged between the first and second chambers. The rotational unit includes a shaft and a mating member arranged in the second chamber and connected to the shaft. The shaft has a first segment arranged in the first chamber and a second segment arranged in the thru-hole. The manipulation ring is spinable to rotate the mating member and the shaft. The waterproof member is configured to seal a gap between the second segment and an inner wall of the case defining the thru-hole. The OTS sensor is arranged in the first chamber and is corresponding in position to the first segment.

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.
