Aptina Imaging has introduced its new image signal processor (ISP) companion chip, MT9S311. The ISP was designed to provide users with greater compatibility with Aptina's 5Mpixel (MT9P001, MT9P012) image sensors. System manufacturers can combine the MT9S311 with an Aptina 5Mpixel sensor to develop highly optimised cameras similar to SoC-based image sensors for a range of applications including surveillance cameras, camera phones, PC cameras, and digital video recorders. The serial (MIPI/CCP2) and parallel interfaces (input and output) provide greater flexibility enabling high definition (HD) video including 720p and 1080p for videos and previews.

Performance focused features

The ISP's image processing engine provides on-the-fly image correction and enhancement as well as on-chip JPEG compression; programmable image overlay with xenon and LED flash support. It is capable of advanced high-definition video, HD modes such as 720p and 1080p in YUV422 or YUV420 formats can be implemented for advanced Web cam and security monitoring applications. Sharp details can be captured and processed in HD utilising simple camera systems designed for consumer use. Aptina provides a unique SoC solution for HD applications when the MT9S311 is combined with Aptina 5MP sensors.

MT9S311 samples are presently available with mass production scheduled in September.
