Contact Image Sensors

Contact Image Sensors

Core technology included in scanners and printers.
Our CIS business is supported by patented technologies.  

Canon Components' contact image sensors (CIS) are incorporated into scanners for conversion of printed text and images to digital data, as well as a wide range of other non-Canon products in diverse fields that require high-precision scanning, such as currency detectors and flaw detection sensors for industrial equipment. Thanks to our flexible response to expanding markets and diversifying customer needs, Canon Components' CIS enjoys strong popularity in the global market.

Devices Including Image Sensors

CIS, which stands for contact image sensor, is an image reading sensor using LEDs as the light source with integrated lenses and sensor ICs for imaging. Our CIS is used as image reading devices in a wide variety of products, since it is easily integrated into the products.

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.

Optical Technology

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.

Feature Requirements

  • Brightness
    Illuminates the document evenly with less power
  • Uniformity
    Illuminates the entire width of the document evenly
    Illumination intensity will not be greatly changed when the documentis partially lifted
    No discoloration due to illumination
  • Depth of illumination
    Illumination reaches farther even the document is partly lifted
