First Consumer HD Recording 3-CCD Camcorder with 16:9 Progressive Scan CCD's
The JVC Everio GZ-HD7 is the first consumer full High-Definition 3-CCD camcorder capable of shooting and recording full HD images (1920 x 1080i), marking the technology's first use in a consumer camcorder.
Featuring a 60GB hard drive
The Everio GZ-HD7 features a large 60GB hard disk drive that can record five hours of full HD (1920x1080i) MPEG2 video with MPEG 1 Layer 2 audio, up to 7 hours in SP mode with a resolution of 1440x1080i, and up to 5 hours in the 1440CBR mode with a resolution of 1440x1080i. Software is provided to transfer video onto blu-ray disks (you must own a blue-ray HD recorder to use this feature).
The GZ-HD7 is equipped with three digital interfaces; USB, HDMI, and i-link. USB is also onboard.
Broadcast HD Camera Fujinon Lens Used for First Time in Consumer Camcorder
The GZ-HD7 camcorder also features a Fujinon lens used in broadcast video cameras, another first in a consumer camcorder. The 3-CCD system offers superior color reproduction.
The highly regarded Fujinon lens used in this JVC camera is also used in broadcast HD video cameras. Three aspherical lens elements provide the superior optical performance over the entire zoom range suitable for an HD system. The 3-CCD system has minimal drop off in F. No. because one of the aspherical lens elements is made of indexed glass. The resulting minimal F. No. is F1.8 wide open and F1.9 for telephoto, while keeping the lens unit small.
In addition, the lens surface is coated with a new Electronic Beam Coating (EBC) as used for broadcast HD lenses. In this process, vaporized chemical material is deposited onto the lens surface with an electronic beam inside a vacuum evaporation device. This coating greatly reduces degradation caused by reflected light on the lens surface, leading to greater light transmission. This reduces detrimental flaring and ghosting as much as possible for black levels.
JVC adjusts the GZ-HD7's three CCDs precisely in the 3-CCD prism on each axis of a 6-axis color matrix before mounting them firmly in place with the high precision appropriate for an HD camera.
Amid rapidly rising market needs for full HD equipment, JVC borrowed from its other high-quality, high-resolution image technologies developed over many years of camcorder research to develop this system, including its progressive CCD camera system, 3-CCD camera system, super high-end processor, and new HD Gigabrid high-resolution signal processing engine.
The camera uses three 1/5-inch 16:9 progressive scan CCDs designed for HD use in a diagonally offset pixel configuration to generate the high resolution image for recording in full HD.
Designed for HD use, the 1/5-inch 16:9 progressive scan CCD has large pixels measuring 3.28 microns x 3.28 microns, roughly twice the size of pixels in JVC 2-megapixel camcorders, for greater modulation transfer function (MTF) and sensitivity values. The CCD aspect ratio was tailored to16:9 for full HD recording in a hard drive camcorder for the first time at JVC. The compact camera unit produces high-resolution images that are recorded in full HD 1920 x1080i resolution.
