The World's Finest Optics Deliver

Canon's GL1 allows you to shoot outstanding video even under the toughest conditions. By combining the most ad-

vanced technologies in lenses and signal processing with manual controls and features, the GL1 achieves a perfect

balance of amazing picture quality and performance versatility. Do all the things the pros do with the Canon GL1.

Achieve Super High

Resolution and

Outstanding Color

Reproduction

3CCD Image Sensors

The GL1 maximizes the

capability of the DV format by

using 3 CCD image sensors.

Each CCD is assigned to

handle one of three primary

colors - Red, Green and Blue.

A beam splitting prism

precisely separates the light

passing through the lens into

individual color components,

and each is sent to its own

CCD. This process achieves

outstanding picture detail,

highly accurate color

reproduction, wide dynamic

range and virtually no color

noise, making the GL1 suitable

for many

professional

applications.

Pixel Shift

Canon employs Pixel Shift, a

signal processing method

used in broadcast TV

cameras, to exceed the overall

picture quality achieved by

camcorders using nearly twice

as many pixels. In addition to

outstanding clarity and natural

color, Pixel Shift provides

wider dynamic range, reduced

vertical smear and sharper still

images. The advantage of

Pixel Shift is clearly visible.

The Process of Pixel

Shift

Each CCD image sensor in the

GL1 includes 270,000 pixels.

The process of Pixel Shift

however, rivals the resolution

of camcorders using CCDs

with 410,000 pixels. The green

component of a video signal

contains 60% of the picture

detail, and the red and blue

components comprise only

40%. The green CCD in the

GL1 is shifted the equivalent

distance of 1/2 pixel from the

red and blue CCD. The green

signal is then sampled more

frequently to extract the

maximum picture detail from

the video signal. This allows

the GL1 to achieve resolution

equal to camcorders with

nearly twice as many pixels.

Also, because there are fewer

pixels on the CCD, they are

larger in size and thereby

gather more light. The result is

improved dynamic range

where detail is clearly visible in

highlights and shadows

without annoying color noise.

Furthermore Pixel Shift greatly

reduces the vertical smear

from bright light sources and

enhances the quality of digital

still images.

Professional

L-Series Fluorite

Lens

Canon has satisfied the

demands of experienced

image makers for years

through the power, design and

quality of 35mm and

broadcast TV lenses. Our

Professional L-Series lenses

utilize Fluorite, a material

which provides outstanding

resolution, contrast and color

reproduction, especially in

lightweight, high-magnification

lenses. Now incorporated into

the lens on the GL1, Fluorite

delivers the ultimate clarity

and image quality. The

Fluorite element inside of the

lens defeats color aberration -

the effect when components of

light stray from one another

within a lens, causing a

reduction in sharpness,

contrast and color. Our

Fluorite lens precisely controls

components of light providing

an excellent balance of these

three critical ingredients of

picture quality. This is

unobtainable with conventional

optical glass.

Optical Image

Stabilizer

Canon's superb optical

stabilization system corrects

camera shake instantly so

even hand-held shots, at full

telephoto, and shots taken

from a moving car, are smooth

and steady. And since it is

optical, there is no loss of

image quality inevitable with

electronic image stabilizers. It

perfectly complements the

high picture quality of the DV

format.
