Aptina announced today a new Clarity+� 13-Megapixel (MP) sensor for smartphone applications, the AR1331CP, which enables mobile phone designers to boost the resolution of their cameras from 8MP to 13MP without compromise. This jump in resolution requires sensor designers to shrink pixels from 1.4 micron (�m) to 1.1�m, significantly reducing pixel performance. Aptina has responded to this challenge with its breakthrough Clarity+technology, boosting pixel sensitivity by a factor of two without introducing the image artifacts that have limited similar approaches from other sensor makers.
"Clarity+ technology uses a Bayer-like pattern with high-fidelity clear pixels that collect two times the light compared to standard green, resulting in a significant improvement in captured signal," said Bob Gove, President and CTO of Aptina. "Clarity+ technology provides the leap necessary to take artifacts and noise out of the equation enabling a world-class image sensor in the mobile-ready, tiny form factor that OEMs need."
The Clarity+ solution starts with the standard 2x2 Bayer RGB color filter pattern commonly used in image sensors throughout the industry, and then replaces all of the green color filters with carefully optimized clear filters. This pattern preserves the high-frequency spatial information of the Bayer pattern, eliminating the aliasing artifacts that are inevitably introduced when both green and clear filters are used in larger kernel (4x4) patterns. The green color is determined through advanced image processing algorithms that use subtractive and interpolation techniques. Specialized noise reduction is then applied, resulting in a 3 decibel (dB) improvement in low-light signal-to-noise ratio (SNR), relative to that possible with the RGB Bayer pattern.
