Optical image stabilization camera module
Abstract:
The present application relates to an optical image stabilization camera module, comprising: a lens; a photosensitive assembly having a photosensitive chip; a first driving part adapted to drive the lens to translate in x-axis and y-axis directions; and a second driving part comprising a second basic portion and a second movable portion, the second driving part having four side surfaces, wherein each side surface is provided with two interlaced SMA wires, and both ends of each SMA line are connected to a fixed end of the second basic portion and a fixed end of the second movable portion, respectively; each of the fixed ends is located at a corner area of the second basic portion or the second movable portion. The photosensitive assembly is fixed to the second movable portion, and the second movable portion is adapted to drive, under the drive of the SMA lines, the photosensitive chip to move in an xoy plane; and the lens and the photosensitive chip are configured to be simultaneously driven and move in opposite directions. According to the present application, the image stabilization stroke and the image stabilization response speed of the camera module can be improved at the cost of a small volume.
