The new 1/3.2” optical format 1.4-micron pixel sensor has the speed to capture the full 8 MP sensor resolution at a rapid 30 frames per second.

Aptina, a provider of CMOS image sensor solutions to mobile device manufacturers and OEMs, has launched the 8-megapixel (MP) AR0833 image sensor with Aptina A-PixHS™ technology. The new 1/3.2” optical format 1.4-micron pixel sensor has the speed to capture the full 8 MP sensor resolution at a rapid 30 frames per second.

A-PixHS technology brings together Aptina’s backside illuminated (BSI) pixel technology and an advanced high speed sensor architecture to enable many innovative features. It is designed to enable low z-height camera modules to meet OEM and mobile device manufacturers' needs. The excellent performance of the AR0833 delivers enhanced image capture capabilities to a variety of mobile devices, including the expanding smartphone market, which according to Techno Systems Research Co, Ltd. is expected to grow 33% in 2012 and account for 65% of all cell phone shipments by 2015.

The combination of BSI and high-speed architecture enable a new class of 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. Zero shutter lag eliminates the annoying delay between when the camera shutter button is depressed and the image is actually captured.

The sensor’s high operating speed enables new advanced image capture options such as HD video with simultaneous still capturing and rapid context switching. Simultaneous capture allows for 8 MP image captures while recording camcorder quality, full field-of-view 1080p HD video at 30 frames per second. Video performance is also enhanced by eliminating the need for cropping the scene or using common “binning” techniques that create image artifacts. The sensor’s rapid contexts 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 currently sampling and will be available in mass production CY Q2 2012. Available as a stand-alone sensor for OEMs and manufacturers who have their own ISP, it is also available with Aptina’s imaging co-processor for a fully tuned, complete camera solution enabling quick integration and delivery of new designs to market.
