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 encoder has a displacement generating unit, a light-emitting unit and an optical navigation integrated circuit. The displacement generating unit has an axle body movable along a central axial line thereof. The axle body has a free end with a diameter larger than a part of the axle body and a planar working surface formed on the free end. The light-emitting unit is configured for operatively providing a light beam to irradiate the working surface of the displacement generating unit. The light beam has a divergence angle within a range to reduce scattering. The optical navigation integrated circuit receives the reflected light beam reflected by the working surface, and calculates a relative displacement between the optical navigation integrated circuit and the working surface.

Abstract: The present disclosure illustrates an optical navigation chip. The optical navigation chip is disposed on an optical navigation module. The optical navigation module includes a light-emitting unit. The light-emitting unit provides a light beam to irradiate a surface of a displacement generating unit. The light beam has a low divergence angle to reduce scattering. The optical navigation chip includes a sensing array and a displacement calculating unit. The sensing array is disposed corresponding to the surface. The sensing array receives a reflected light beam which the surface reflects, and captures an image once every capturing interval based upon the reflected light beam. The displacement calculating unit calculates a relative displacement between the optical navigation chip and the surface according to the images.
