CMOS Imaging IC
AMI Semiconductor introduces a CMOS imaging IC for intelligent camera applications. The AMIS-70700 optoelectronic device has been developed in partnership with CMOS image sensor and camera specialist Photonfocus AG. The device will simplify the design and implementation of high quality digital camera applications in automotive, industrial, security and surveillance systems. The AMIS-70700 can be used at temperatures ranging from 40° C to 105° C. The IC combines low fixed pattern noise with a very high signal-to-noise ratio (SNR) and uses built-in compensation techniques to minimize high temperature leakage. Use of the Photonfocus LinLog technology contributes to the IC’s range and ensures acquisition of high contrast images without image lag or smear, even at high frame rates. LinLog overcomes the drawbacks of pure logarithmic image sensors by using a linear response at low illumination levels and logarithmic compression at high intensities. Transition between the two is optimized to prevent artifacts and discontinuities.
