The HD Everio GZ-HD3 offers HD (High Definition) recording with 1440x1080i resolution. These HD pictures are extremely fine and detailed, containing 4.5 times the visual information of conventional SD (Standard Definition) pictures. With a 60GB built-in hard disk drive you can record up to seven hours of HD video (SP mode), plus you get two additional recording modes to select according to your requirements.
For bright, realistic colors the HD Everio uses three 1/5-inch CCDs — one each for red, green and blue. Naturally, by having dedicated CCDs for each primary color, the camera is able to gather the maximum visual information which leads to more realistic color reproduction and presence. Using Pixel Shift Technology, the Red and Blue pixel locations are shifted relative to Green, allowing the sampled color information to be quadrupled through interpolation.
The HD lens of the GZ-HD3 was developed by camera specialist, KONICA MINOLTA, to ensure that the lens performance was optimized for use with our 3-CCD image sensor and MPEG-2 recording technology. The result is an extremely detailed picture with clear contrast and strong presence throughout the image — the type of stable and consistent performance that becomes essential when recording images at HD specifications. The lens structure also contributes to the miniaturization of the camera.
Developed specifically for HD Everio, the GZ-HD3's HD Gigabrid Engine processes the CCD images as a progressive scan signal. This provides the maximum image information to work with, regardless of the actual recording mode that is used. Also integrated into the chip are five digital noise reduction technologies that collaborate to improve vertical resolution by about 30% from previous JVC Standard Definition camcorders. It's at the heart of JVC's HD recording system.
