Abstract: An optical system is provided, including a holder, a fixed module, a driving assembly, and a first resilient member. The holder is used for holding an optical element that defines an optical axis. The fixed module is movably connected to the holder and has a housing and a base connected to the housing. The base has a bottom surface parallel to the optical axis and a first pillar forming a first surface not parallel to the optical axis. The driving assembly drives the holder to move relative to the fixed module. The first resilient member is disposed on the first surface and movably connecting the holder with the fixed module.

Abstract: An optical system is provided, including a liquid optical module and a first optical module. The liquid optical module includes a liquid lens driving mechanism and a liquid lens assembly. The liquid lens driving mechanism includes a fixed portion, a movable portion and a first driving assembly configured to drive the movable portion to move relative to the fixed portion. The liquid lens assembly includes a liquid lens element, a fixing member and a deforming member. The first optical module is disposed in a receiving space of the fixed portion and includes: a first optical element and a first optical driving mechanism. When the movable portion is driven by the driving assembly to move relative to the fixed portion, the liquid lens element is deformed via the deforming member, causing the optical properties of the liquid lens element to change.

Abstract: An optical system is provided and includes a fixed assembly, a movable member, a driving assembly and a buffering member. The movable member is movably connected to the fixed assembly and is configured to hold an optical member having an optical axis. The driving assembly is for driving the movable member to move relative to the fixed assembly. The buffering member is disposed on a first surface of the fixed assembly. The buffering member, the movable member and the fixed assembly are arranged along the optical axis. The buffering member includes a soft resin material. The buffering member is disposed to surround the optical axis.

Abstract: An electromagnetic driving mechanism is provided, including a housing, a circuit unit, an electromagnetic driving assembly, and a sensing element. The circuit unit is connected to the housing, and has a plastic material and a circuit element. The plastic material is formed on and covers an outer surface of the circuit element by insert molding. The electromagnetic driving assembly is disposed in the housing for forcing an optical element to move relative to the circuit unit. The sensing element is disposed on the circuit unit, and electrically connected to the circuit element for detecting the displacement of the optical element relative to the circuit unit.

Abstract: A method and an apparatus for eliminating chromatic aberration are provided. The method includes: calculating out a position weight of a pixel according to the position of the pixel in an image, calculating out an edge response of the pixel and converting a chrominance of the image pixel into a hue; using the edge response of the pixel to calculate out a hue range; and finally correcting the hue of the image pixel by using the position weight, the edge response and/or the hue range.

Abstract: A double buffering device and operating method thereof are provided to provide data to a second device, comprising a controller, a first buffer and a second buffer, a bus and a software unit. The controller controls data access. The first and second buffers coupled to the controller store the data. The bus is coupled to the controller for data delivery. The software unit provides data to the buffers via the bus. In a first mode, the software unit programs the first buffer with the data, the controller synchronizes the data from the first buffer to the second buffer, and the controller copies the data from the second buffer to the second device. In a second mode, the software unit simultaneously programs the first and second buffers with the data, and the controller copies the data from the second buffer to the second device.
