Abstract: A control method of a driving mechanism is provided, including: the driving mechanism provides a first electrical signal from a control assembly to the driving mechanism to move the movable portion into an initial position relative to the fixed portion, wherein the control assembly includes a control unit and a position sensing unit; the status signal of an inertia sensing unit is read; the control unit sends the status signal to the control unit to calculate a target position; the control unit provides a second electrical signal to the driving assembly according to the target position for driving the driving assembly; a position signal is sent from the position sensing unit to the control unit; the control unit provides a third electric signal to the driving assembly to drive the driving assembly according the position signal.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A vehicle-reversing display system includes a controller area network, a vehicle-reversing image capture device and a display device. The vehicle-reversing image capture device includes a controlling unit, a first image camera unit and a second image camera unit. The first image camera unit includes a first camera control unit and a first sensor. The second image camera unit includes a second camera control unit and a second sensor. The controlling unit judges a driving scenario according to vehicle-reversing parameters from the controller area network. The first image camera unit and the second image camera unit are automatically enabled or disabled according to the driving scenario.

Abstract: A diffuser film and a method of manufacturing the same are proposes. A colloid layer is formed on a transparent substrate. A mold plate with a raised texture is then used to roll over the colloid layer to let the surface of the colloid layer have an indented texture. Finally, a solidification process is carried out to harden the colloid layer to form a coarse layer whose surface has an indented texture. The diffuser film can thus achieve the effects of light concentration and light uniformity promotion, and can also reduce astray light rays. Moreover, using a mold plate for embossing can accomplish high reproducibility of film thickness and indented texture of the coarse layer, hence being advantageous to mass production.
