About Mitsubishi Electric Contact Image Sensors
Contact Image Sensors (CIS) are image sensor made of a sensor (photodetector), illumination (LED) and GRIN lens. Compared to conventional cameras, CIS can be used closer to the surface of the object being scanned and obtain more compact images.
Based on know-how accumulated over many years, we have originally developed high-speed, high-functional AFE and ASIC for CIS.
We have originally developed key parts, such as high-SNR CMOS sensor ICs with an extremely efficient illumination.
Maximum speed of 20μs/line (banknote applications)
Maximum speed of 20μs/line (copy machine applications)
White light source with higher brightness and lower power consumption (copy machine applications)
Visible (RGB), infrared (IR) and ultraviolet (UV) light source combinations possible (banknote applications)
Improved operation ease thanks to enhanced image-processing functions such as pixel interpolation, color reproduction processing (NCM) and drop out color.
Our CIS satisfy regulations for the applicable six substances, making them products that can be used anxiety-free.
* RoHS directive. Restricts the use of six hazardous substances in electronic and electrical equipment sold in countries of the EU from July 2006.
We will continue to provide high-quality, high-performance and highly reliable CIS based on know-how accumulated from a track record spanning more than 30 years.
CIS are widely used instead of line cameras as surface inspection devices to detect faulty conditions like scratches, dirt, missing parts, coloring, and positioning of printed documents, plastic film, circuit boards, sheet iron, etc.
High-speed scanning is possible with our independently unique developed CMOS sensor IC / ASIC and various light sources (RGB, IR and UV). Used for authenticating items such as banknotes.
