Specifications and Features of Copy Machine Applications
By utilizing our original CMOS sensor and color filter with equivalent spectral characteristics to that of CCDs used for the front surface scanners of copy machines, the CIS provides color compatibility equivalent to that of a CCD. We have developed a CIS that can be used either for surface scanning or ADF applications.

The specifications provided above are for reference only. We customize our CIS for copy machine applications to meet each customer’s requirements.
This product utilizes a color filter system and converts information of the source document to an electric signal using a white LED illumination and a sensor IC with the three color filters of red, blue and green (RGB).
Additionally, color compatibility with CCD has been achieved by adopting a color filter equivalent to those used for CCD systems.
Color filter system
Reference: Sequential lighting line-scan system
Advantages compared to Sequential lighting line-scan system
1. No color displacement in the direction of sub-scanning.
2. Good RGB color reproduction.
3. Good fluorescent color reproduction.
4. Less moiré when scanning an image containing a high number of lines.
5. Monochrome scanning speed is three times faster than color scanning.
Mitsubishi Electric CIS are line sensors configured from multiple semiconductor sensor ICs independently developed in-house.
A total of 24 sensor ICs, each 300㎜ in size, are aligned at a pitch of 42μm. Alignments between sensor ICs are performed at an accuracy within one-third of a pixel (approx. ±15μm).
