Main Features of HD Everio GZ-HD3
1. 3-CCD Camera System for 1440x1080 HD Recording
•
By
using three 16:9 progressive scan CCDs
, each dedicated to one of the three primary colors –
red, green, blue – the image sensor can capture truly lifelike images and deliver vivid and accurate
color reproduction. Since the CCDs themselves are 16:9, they record a pixel array with native 16:9
dimensions for viewing on an HDTV and authoring to DVD or Blu-ray disc. The lens block also uses
CCD pixel shift technology to increase horizontal and vertical resolution.
●
As is the case with the GZ-HD7, the GZ-HD3’s image processing is driven by JVC’s
HD Gigabrid
Engine,
which processes images from the progressive CCDs in native progressive to maintain as much
quality as possible while applying five different noise reduction technologies to improve vertical resolution
by approximately 30 percent from previous JVC Standard Definition camcorders. Images are reproduced
with the depth and richness only possible with high-definition television, and feature natural skin tones,
and vivid, glossy colors, especially green.
