The camera's CCD (charge-coupled device) plays a

critical role in picture quality. That's why Panasonic

chose a 3CCD camera system – the type used in

professional video cameras. In this advanced system

the incident light is split into its three primary colour

components (red, green and blue), and the resulting signal from each is collected

by one of the three CCDs. The GS250’s 3CCD system features a total of 800,000

pixels times 3. It captures moving pictures with an effective 630,000 pixels times 3

and still pictures with an effective 710,000 pixels times 3, which provides highly

detailed colour information. Compared with conventional 1CCD camera systems,

Panasonic's advanced 3CCD system gives you greater beauty three different ways:

in colour, detail, and gradation.

Leica is renowned by photographers everywhere as a maker of superb cameras

and lenses. Now this legendary optical technology fuses with Panasonic's advanced

digital technology in the Leica Dicomar lens. The GS250's brilliant new lens features 13

lens elements in 9 groups and uses low-dispersion optical glass to reduce chromatic

aberration to about 1/3 the level of conventional lenses. A special multi-coating

process is applied to 14 lens surfaces, minimising harmful reflection to deliver crisp,

clear images free of flare and ghosting.

3D RGB Frame Noise Reduction

The noise reduction system uses a noise-shaping filter (first

dimension) to remove the rough, highly visible noise. Next, it extracts and analyses data from

several adjacent pixels in the horizontal and vertical directions (second dimension), and removes

any parts that it determines to be noise. Finally, the process is applied to the time axis (third

dimension), where it extracts and analyses several frames, and again removes parts that it

determines to be noise. The result is a better noise-reduction performance than conventional

systems provide. The noise reduction is particularly effective when shooting at low illumination,

so you can capture clear, sharp images even at night or when lights are low.

AXIS (Advanced Pixel Interpolation System)

Quad-Density Pixel Distribution technology improves image precision by interpolating the signal

for areas on the CCD where there are no pixels. AXIS helps reproduce even finely detailed

portions of an image, giving the picture a higher-resolution appearance.

Digital Signal Processing

This new configuration consists of two separate image processing circuits, one for moving

pictures, one for still pictures. Using the optimum circuit for each type of picture makes it

possible to record both with outstanding quality.

3.1-Megapixel Still Picture Recording GS250

The GS250 features Quad-Density Pixel Distribution, a technology

used in Panasonic's professional equipment. By distributing the pixels

at intervals measured in submicrons, this technology makes it

possible to position four times as many pixels as in a conventional

CCD. As a result, the GS250 records

3.1-megapixel still pictures. It captures all of the

outstanding detail, colour and sensitivity made possible

by the 3CCD camera system.
