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 electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit emits light to the structure, captures reflected light from the structure to sense/receive an image from the surface of the structure, detects displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.

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: An optical detecting device is utilized to determine a relative position of a reference object or a light source according to an optical reflecting signal reflected from the reference object via an optical detecting signal emitted by the light source. The optical detecting device includes a light penetrating component, at least one light tight structure and an optical detecting component. A focal length of the light penetrating component is greater than a predetermined distance. The light tight structure is located on a region correlative to the light penetrating component. The optical detecting component is disposed by the light penetrating component and spaced from the light penetrating component by the predetermined distance. The optical reflecting signal is projected onto the optical detecting component through the light penetrating component to form a characteristic image via the light tight structure, and the characteristic image can be used to determine the relative position.
