  • Page 9: Features

    It is an important model as a milestone for manufacturing Canon's own projectors. The LV-S1 is the first SVGA model equipped with the first optical box made by Canon and has been developed as a model in the Canon's lineup of new-generation projectors.

  • Page 10: Major Features

    High intensity 1100 ANSI lumen The Canon's original optical design achieves 1100 ANSI lumen, which is the highest brightness in the 0.7-inch class. Real XGA projection, high-quality projection by SXGA digital compression Real XGA projection is implemented using a 0.7"...
  • Page 11 The projector has the first F1.6 zoom projection lens in the industry. In addition, it contains a lot of Canon's outstanding optical components, such as a newly developed high-refractivity 4P color synthesis prism, a free curved surface mirror and a fluorite field lens to provide the highest intensity and highest-quality video output in its class.

  • Page 15: Commentary

    The operation panel is finished so that the focus ring and zoom lever show the Canon's brand image. The operation panel on the top is tilted to the rear to improve operability and buttons are laid out around the cursor keys so that they can be operated by touching with a hand without looking at them.
  • Page 16 A free curved surface mirror is used in the red light path optical system whose optical path length is different from that of other channels. The Canon's free curved surface design technique reduces the number of parts and reduces weight drastically compared with the conventional relay optical systems.
  • Page 17 Part 1: General Information LV-S1 (Only different points from the LV-X1 are described below.) A newly developed high-refractivity 4P color synthesis prism is adopted to minimize deterioration of picture quality due to the color synthesis prism. A short arc lamp, a large aperture LCD panel, an illumination optical system and a F1.6 zoom lens suitable for the LCD panel are used for optimum design to achieve the highest brightness of 1000 ANSI lumen in the 0.7-inch class.
