GZ-MG20拥有20GB 内置硬盘,80万像素 CCD 以及25倍光学变焦,其体积非常小巧,重量也只不过380克。它沿用了传统数码摄像机主流的2.5英寸液晶屏。GZ-MG20可以持续摄录并存储约四个半小时的MPEG-2格式 DVD 画质的动态影像。它在 JVC 的系列硬盘摄像机中属于入门级产品,能够拍摄640×480像素分辨率的照片。所有的照片都是以 JPEG 格式存储在硬盘中的。同时,机器底部设计了 SD 卡槽,提供了扩展功能和另一种读取方式。JVC 采用了双重保护的结构,在硬盘外面有一个独特的悬浮结构,能够有效地防止硬盘工作时受到的震动。此外,它借鉴了在笔记本电脑上已经得到广泛应用的三维重力感应器,在突然失重的情况下可以及时切断硬盘电源,保护硬盘内数据的安全,
GZ-MG20 has a 20GB built-in hard drive, 800000 pixel CCD and 25x optical zoom, the size is very small and weighs only 380 grams. It follows the mainstream 2.5-inch LCD screen of a traditional digital video camera. GZ-MG20 can continuously record and store about four and a half hours of MPEG-2 format DVD quality video. It is an entry-level product in the JVC family of hard disk camcorders capable of capturing 640 x 480 pixel resolution photos. All photos are stored on the hard drive in JPEG format. At the same time, the bottom of the machine is designed SD card slot, provides an extension of functions and another way to read. JVC uses a double protection structure, has a unique suspension structure outside the hard disk, can effectively prevent the hard disk from vibration. In addition, it draws on the laptop has been widely used three-dimensional gravity sensor in the case of sudden weight loss can be promptly cut off the hard disk power, data protection within the hard disk security,
