Image sensor brings full 8M-pixel resolution at 30f/s to smartphones

February 22, 2012 // By Julien Happich
Aptina has launched an 8-megapixel image sensor featuring the company's A-PixHS technology. The AR0833 1/3.2” optical format 1.4-micron pixel sensor has the speed to capture the full 8 MP sensor resolution at 30 frames per second. Aptina’s A-PixHS technology brings together the company’s backside illuminated (BSI) pixel technology and an advanced high speed sensor architecture to enable a number of innovative features.

It is designed to enable low z-height camera modules to meet OEM and mobile device manufacturers' needs. The AR0833 delivers enhanced image capture capabilities to a variety of mobile devices. 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.
