Omnivision Announces Improved Version of 8MP/30fps 1.4um BSI-2 Pixel Sensor

Business Wire: OmniVision announces the OV8865, a low-power, high-performance 1/3.2-inch 8MP sensor targeting mobile devices, including advanced smartphones and tablets. Featuring an improved 1.4um OmniBSI-2 pixel, the OV8865 is said to deliver better pixel performance in a smaller package and uses less power when compared to the previous-generation OV8835.

"Reports are predicting that more than 1.8 billion smartphones and 250 million tablets will be produced annually by 2015[1], with the majority of this growth expected to come from developing markets like China and India. We are bringing to market the OV8865 at a time when manufacturers in these booming markets are looking for a cost-competitive camera solution for their slim and feature-rich devices with extended battery life," said Harish Iyer, product marketing manager at OmniVision. "The 8-megapixel OV8865 has been re-engineered from top to bottom. With an enhanced 1.4-micron OmniBSI-2 pixel, the OV8865 has improved camera performance and image quality when compared to our last generation 8-megapixel sensor, and offers smaller package-size and lower power consumption."

The OV8865 provides a number of performance improvements over the previous generation OV8835 CameraChip sensor: dark current has been reduced by 50% and DR is improved by 5% (should be 15% or 1.5dB: was 68.7dB, now 70.23dB). Additionally, the OV8865 consumes less power when compared to the OV8835, achieving the sub-200 mW benchmark currently favored by many high-end mobile device manufacturers. Both new and old sensors have 30fps speed at full resolution. The sensor also delivers 1080p30 or 720p60 video with EIS. The OV8865's 2 x 2 binning functionality with post-binning resampling filter minimizes spatial artifacts.

The OV8865 comes in a smaller footprint when compared to the OV8835, fitting into 8.5 x 8.5 x 5 mm module. It is currently available for sampling and is expected to enter volume production in the Q4 2013.

  1. What was the earlier power consumption?

    1080P30 is old school, there are sensors in that optical format (with 8MP) doing 1080P60 and 720P120 with full FOV.

  2. So what is dark current at, say, 60C? Didn't see it in the flyer.

  3. I just came across the "post binning resampling filter" (also found on other sensors). Has anybody any info / link on how and how well this works?
