Abstract

A zoom camera having a lens barrel assembly with adjustable focus and resolution power of photographing lens, the zoom camera including a zoom lens barrel assembly including a plurality of barrels for performing a zooming and focusing operation while reciprocating in a direction of an optical axis, the zoom lens barrel assembly being fixed on a camera body, a rotational barrel coupled to one of the lens barrels of the zoom lens barrel assembly and rotatable and movable in the direction of the optical axis for adjusting the focus of the lens, and a lens frame containing a lens and rotatably coupled to the rotational barrel for adjusting the resolution power of the lens.

Description

[0001] This application claims priority from Korean Unexamined Patent Application No. 2003-23779 filed on Apr. 15, 2003. technical field [0002] The present invention relates to a camera, and more particularly to a zoom camera having a lens barrel assembly designed to adjust the focal length position and resolution of the lens to compensate for focal lengths often caused by machining tolerances during the manufacture of the lens barrel assembly and resolution errors. Background technique [0003] Whether a film-type camera or a digital camera, a zoom camera generally includes a zoom lens barrel assembly having a zoom function to change the magnification (ie, focal length) of a photographic lens and a focus function to change focus in response to an object distance. [0004] The zoom lens barrel includes a front lens barrel assembly and a rear lens barrel assembly. The rear lens barrel assembly includes the lens, and the focal length of the lens may deviate slightly from th...
