Aptina Imaging Corp. has unleashed an image sensor that touts the company's A-PixHS technology. The AR0833 features 1/3.2in optical format and 1.4? pixel sensor that has the speed to capture the full 8MP sensor resolution at 30fps. According to the company, the device enhances image capture capabilities of mobile devices including smartphones.

Aptina's A-PixHS technology combines its backside illuminated (BSI) pixel technology and an advanced high speed sensor architecture to enable low z-height camera modules to meet OEM and mobile device manufacturers' needs. This yields ultra-responsive cameras with excellent low light performance and uncompromised bright light performance to capture images with zero shutter lag and suppressed rolling shutter artifacts, boasted Aptina. Zero shutter lag eliminates the annoying delay between when the camera shutter button is depressed and the image is actually captured.

Simultaneous capture allows for 8MP image captures while recording camcorder quality, full field-of-view 1080p HD video. Video performance is also enhanced by eliminating the need for cropping the scene or using common "binning" techniques that create image artifacts, explained the company. The sensor's rapid context switching feature also removes shutter lag when the sensor switches between a low-power preview mode and a full resolution still image. Additionally, the AR0833 is HDR ready for still and video applications, capturing difficult high range scenes when coupled with an HDR processor.

The AR0833 is sampling and will be available in mass production in 2Q12. Available as a standalone sensor for OEMs and manufacturers who have their own ISP, it is also available with Aptina's imaging co-processor.
