The World's Finest Optics Deliver Canon's GL1 allows you to shoot outstanding video even under the toughest conditions. By combining the most advanced 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. CCD B CCD G 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 CCD R 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. Fluorite lens Conventional optic lens 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.
