Agilent Technologies Inc. (NYSE: A) today introduced a single-chip 1.3 megapixel CMOS image sensor featuring an enhanced-performance (EP) pixel architecture that allows mobile phones and computing devices to take sharper, truer color photos in all lighting conditions. The new image sensor, with its 10X reduction in noise, eliminates the CMOS-CCD image-quality gap and targets high-image-quality megapixel mobile phone, computing, security and industrial applications.
The sensor’s on-chip image processing and JPEG compression eliminates the need for a space-consuming, power-hungry companion chip and reduces design complexity and time to market. Agilent’s proprietary EP pixel architecture leverages several design innovations, such as 3-D pixel e-field shaping(1), to better address the three major challenges faced by all CMOS image sensors: keeping noise down in very low-light conditions, maintaining true color uniformity for sharpness and color accuracy, and improving pixel consistency through reduced manufacturing variability.
The EP pixel architecture maximizes photodiode area in a highly symmetric 3.3 micron active-pixel design that provides a 10X reduction in dark current and surface-state noise for richer, more brilliant color-image reproduction. In addition to lower noise and dark current, it delivers lower crosstalk, higher blue sensitivity and true correlated double sampling. It also includes patent-pending innovations that significantly reduce image lag for superior results in low-light and video applications.
“The sensor is the critical link in capturing high-quality light data and feeding the image processor with the most signal, least noise and sharpest-definition raw data,” said Feisal Mosleh, director of Mobile Imaging Marketing in Agilent’s Semiconductor Products Group. “Our new EP pixel architecture offers best-in-class data capture, resulting in remarkable low-light performance and deep contrast for incredibly sharp and brilliant color images at all light levels. At 1.3 megapixels, the color reproduction, low-light performance and image sharpness is industry-best. We intend to implement our enhanced-performance pixel architecture at higher resolutions to produce digital still-camera-like results.”
“Our close cooperation with Agilent on 0.18 micron CMOS image sensor process improvements has resulted in a more consistent process with greater uniformity and better yield,” said Ken Chen, director of mainstream platform marketing at TSMC. “We look forward to applying this improved EP process to all of Agilent’s future multi-megapixel imaging system chips.”
ADDC-3960 EP 1.3 Megapixel Image Sensor
The Agilent ADCC-3960 EP is the industry’s most advanced one-third optical format, 1.3 megapixel system-on-chip. It incorporates a CMOS image sensor with an enhanced image processor and seventh-generation JPEG compression engine.
The sensor is capable of 15 frames per second at full SXGA resolution, and 30 frames per second in VGA mode. It has a pixel size of 3.3 micron square and contains 1,280 horizontal by 1,024 vertical active pixels. The ADCC-3960 EP also incorporates a 10-bit A/D converter and offers these key image-processing features:
oSpecial-effects generator with “blue people,” black & white, sepia, solarization and 20 other special effects(1).
oAdaptive compression that ensures highest-quality JPEG compression with no dropped frames(1).
oAdvanced exposure control for brighter non-flash images(1).
oEnhanced automatic pixel correction that’s 5X better than conventional bad pixel amelioration(1).
oTrue color image processing that’s better than advanced auto white balance(1).
oProgrammable dual LED and Xenon flash strobe synchronization(1).
oLocally adaptive color noise suppression(1).
oSmooth 4X digital zoom to emulate an optical zoom movement(1).
oAnti-vignetting that provides automatic correction for lens shading effects.
oPicture sharpening and adaptive tone mapping.
oAuto flicker correction.
Agilent expects to sample an EP-based 2-megapixel CMOS image sensor in early 2006. Further information on Agilent’s CMOS image sensors is available at www.agilent.com/view/imaging.
