A navigation trace calibrating method and a related optical navigation device are utilized to transform a first trace line generated by the optical navigation device into a second trace line suitable for user operation. The navigation trace calibrating method includes establishing a reference coordinate system, reading and analyzing the first trace line, calculating a first offset of the first trace line relative to the reference coordinate system, defining an offset between the first trace line and the second trace line as calibration weight to acquire a second offset of the second trace line relative to the reference coordinate system, and calculating a value of the calibration weight according to the second offset and a length of the first trace line.


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.

A signal sampling method, applied to a sensing system comprising a sensing matrix with a first sensing region and a second sensing region. The signal sampling method comprises: (a) applying a first single period sampling number to sample a sensing value of the first sensing region to generate a first sensing signal; and (b) applying a second single period sampling number to sample a sensing value of the second sensing region to generate a second sensing signal. The values of the first single period sampling number and the second single period sampling number are different. The selection for the single period sampling number is extended via sampling different sensing regions by different single period sampling numbers.

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.
