Aptina has recently added the Aptina Clarity+ technology to its portfolio of sensor and imaging technologies. Building on the company's 1.1micron image sensors, Aptina's Clarity+ imaging technology aims to further increase performance in these sensors to surpass today's top 1.4micron BSI pixel sensors. Further, leveraging Clarity+ technology with future generations of pixels, including 0.9?m pixels, will power mobile phones to greater than 20Megapixels.

"Clarity+ technology enables a substantial improvement in picture clarity when capturing images with mobile cameras. While many others have introduced technologies that increase the sensitivity of cameras with clear pixel or other non-Bayer colour patterns and processing, Aptina's Clarity+ technology achieves a doubling of sensitivity, but uniquely without the introduction of annoying imaging artifacts, " said Bob Gove, President and Chief Technology Officer at Aptina.

Clarity+ technology builds on 3rd generation Aptina A-PixHS technology enhancing image quality even more, resulting in overall performance improvements beyond those achieved with the current industry standard, the 1.4micron BSI pixel. Additionally, this technology works seamlessly with 4th generation Aptina MobileHDR technology, increasing dynamic range for both snapshot and video captures by as much as 24dB.

"This optimised performance is enabled by innovations in the sensor and colour filter array design, along with advancements in control and image processing algorithms. Our total system approach to innovation has led prominent OEMs to confirm that Clarity+ technology has clearly succeeded in producing a new level of performance for 1.1um pixel image sensors. We see Clarity+ technology playing a significant role in our future products, with initial products in the Smartphone markets," added Gove.

Attempts to advance the standard Bayer pattern, which has been the standard since the 1970s, have not been successful until now. Aptina's 2000-plus worldwide issued and pending patents reflect the company's commitment to image sensor technology which has enabled the successful development of this new technology. The technology combines CFA, sensor design and algorithm developments to collectively deliver stunning images. It is fully compatible with today's standard sub-sampling and defect correction algorithms, which means no visible imaging artifacts are introduced. While BSI technology innovation drove 1.4micron pixel adoption, Clarity+ technology will drive 1.1micron pixel adoption into the Smartphone market.

The company will incorporate this innovative technology into a complete family of 1.1micron and 1.4micron based products addressing both front and rear facing applications. The Aptina AR1231CP 12MP, 1.1micron mobile image sensor is the first sensor to support Clarity+ technology. This 1/3.2inch BSI sensor is capable of 12MP resolution at 60fps and supports 4K UHD video at 30fps. The Aptina AR1231CP is now sampling.
