OmniVision this morning unveiled a new camera sensor that could improve the image quality for the iPhone and other smartphones. The OV8820 upgrades to an eight-megapixel, CMOS-based sensor that can capture well in low light and boasts electronic stabilization to minimize shake. Video is now more of a focus as well, Omnivision said: it can record at 1080p30 or 720p60 with hardware scaling and a minimum amount of the "tower of jello" rolling shutter effect that can creep up in this format.
