Problems solved by technology

Therefore, a focusing lens and a driving unit for focusing at a specific magnification are required, and since a final reduction gear and a lens holding structure that move along the cam are additionally required, the driving tool becomes unfavorably complicated and large in size

Embodiment Construction

[0036] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Through the arrangement and movement stroke of each lens unit, a zoom function of an optical instrument such as a camera is realized. The zoom function is used to photograph an object at a distance away from an optical instrument such as a camera as if it were positioned closer. Using a zoom camera, a larger image of the same object can be obtained. Meanwhile, generally, the zoom function can be divided into an optical zoom function and a digital zoom function. The optical zoom function is defined as changing the distance between the lenses to realize the zoom function, and the image sensor with low resolution can be advantageously used without damaging the image quality. Meanwhile, digital zoom can advantageously provide an image with high exposure at a specific location, but at the expense of image quality. The digital zoom f...

Abstract

Provided is a compact lens module which enables zoom and auto-focus functions even in a small lens module by providing a lens carrying structure using a supersonic driving unit. A lens unit is positioned in a case and has at least one lens. A carrying member is rotatably connected in the case and connected to the lens unit so that the lens unit may move forward and backward. In addition, a driving unit is mounted in the case for transferring a driving force to the carrying member so as to move the lens unit by repeatedly contacting and non-contacting with the carrying member.

Description

[0001] This application claims priority from Korean Patent Application No. 2004-14769 filed in the Korean Intellectual Property Office on Mar. 4, 2004, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a lens assembly, and more particularly, to a small lens assembly that provides a lens carrying structure to enable zooming and autofocus functions even in a small lens assembly by using an ultrasonic driving unit. Background technique [0003] Camera technology has developed from film cameras, which use film, to digital cameras, which convert images into digital signals. In recent years, such digital cameras are being miniaturized and started to be applied to personal mobile communication terminals. The quality of a digital camera mounted on a personal mobile communication terminal, such as a cellular phone, is based on the number of pixels of an image sensor that is continuously increasing, and today, digital...
