Camera lens assembly for mobile phone {CAMERA LENS ASSEMBLY FOR A CELL PHONE}

The present invention relates to a camera lens assembly, and more particularly, to simultaneously perform an autofocus function mounted on a mobile communication terminal to automatically adjust the focus of an image, and a shutter function to adjust a quantity of light incident on an optical path to enable clear image capturing. The present invention relates to a camera lens assembly for a mobile phone, in which an autofocus device and a shutter device are integrally formed so as to be slimmer and smaller.

Recently, with the development of digital camera manufacturing technology, a compact and light weight camera lens assembly has appeared, so that a camera can be mounted in a mobile communication terminal, and a mobile communication terminal equipped with an optical lens and a camera element is becoming popular.

  In the early days when cameras were installed in mobile terminals, the performance of cameras mounted in mobile terminals was significantly lower than that of commercially available digital cameras. For example, when the performance of entry-level digital cameras was 4 million pixels, cameras mounted on mobile communication terminals were generally 300,000 pixels, and those equipped with high-end terminals were only 1 million pixels.

  Recently, it has been popular to mount a 1 million to 2 million pixel camera on a mobile communication terminal. A high-end terminal is equipped with a 3 million pixel camera, which is equivalent to a low-end digital camera, and a camera having a performance of 7 million pixels or more. Succeeded in commercializing mobile communication terminals.

As the camera mounted on the mobile communication terminal becomes more than 3 million pixels high in performance and generalization, the mounting rate of the camera with the built-in autofocus function for correcting the focal blur caused by the shooting distance of the subject when the image is taken is increasing. As the research and development of the camera lens assembly is actively progressed by the user's request for a clearer image, the technical development of the camera lens assembly is accelerated.

  Although the performance of the camera lens assembly and the precision of its fabrication technology have improved, and the mobile communication terminal is gradually eroding the digital camera market, considering the main intelligence of the mobile communication terminal, that is, the maintenance and portability of the communication function, the mobile communication There is a limit to the performance of the camera mounted on the terminal to the same level as that of the digital camera.

  That is, even in a typical compact digital camera, an optical zoom function, an auto focus function, and a shutter function are basically installed. In addition, some cameras are equipped with image stabilization. However, since mobile communication terminals have to take portability into consideration as the main function of communication, optical zoom, autofocus, and shutter can be installed even with a camera lens assembly. It is having a hard time installing functions and image stabilization functions.

In detail, the optical zoom function and the shutter function of the camera lens assembly mounted in the mobile communication terminal are limited in terms of space limitations and performance difficulties, and the space is relatively used than the optical zoom function and the shutter function.
