CIS Technology


In order to secure enough LED light in its CIS, Canon Components tirelessly researches and develops the LED instllation angle, the shape of the light guide directing the LED light towards the document, and other aspects, thereby making it possible to utilize light sources in an ideal manner. In addition, we have acquired a large number of related patents.
CIS consumes less than a tenth of the electricity used by CCD-based image reduction systems. Not only does this represent a major environmental benefit, it also plays a major role in enabling USB bus powered scanners that do not require an AC power source. Additionally, the scanning component is 1/10 - 1/20 the size of CCD-based components.

small-volume custom components
to mass produced parts.

LIDE (LED Indirect Exposure)

Photo:LIDEiLED Indirect ExposurejgLIDEh has been a major contributor to making Canon scanners more compact and power efficient. LIDE uses small, lightweight and power efficient LEDs as the light source. While it was traditionally difficult to obtain sufficient amount of light from LEDs, our research into installation methods and light guides has overcome this hurdle. An indispensable component to LIDE are the CIS developed and manufactured at Canon Components. By arranging a CIS at the same width as the platen, scanners can read the document with no distortion from edge to edge. This has eliminated the need for reduced projection lenses and enabled products to offer dramatic reductions in size and weight.

Optical Technology

Photo:Optical simulation Light guide is the one of the essential component of LIDE technology.
Canon Components makes continuous improvements to meet our customers' strict feature requirements (brightness, uniformity, depth of illumination, etc.), based on our proprietary, time-proven technology.
The precision of the light guide design is improved through the full use of optical simulations, which have also reduced the use of prototypes and the time required for development.
