The 1/2.3-inch OV16820 and OV16825 sensors are capable of operating in full resolution (4608 x 3456) video at 30fps, 4K2K (3840 x 2160) video at 60fps, and 1080p HD video at 60fps with extra pixels for EIS. Their image processing functions include defective pixel and noise canceling, RAW scaling, image size, frame rate, exposure, gain, cropping and orientation are programmable through the serial camera control bus (SCCB) interface. The sensors have up to 8-lane MIPI and LVDS data outputs.
"It was an industry-wide assumption that smartphones would cut into DSC/DVC sales; but at higher resolutions, we're seeing a very distinct divide between the two markets and both remain strong," said Devang Patel, senior product marketing manager at OmniVision.
The OV16820 is available for sampling in a ceramic land grid array (CLGA) package while the OV16825 will be available in die form (RW/COB). Lens CRA is 8.5deg (non-linear) for DSC/DVC version or 29.7deg (non-linear) for the mobile version. Both sensors are expected to enter volume production by Q4 2012.

Is the sensor using chip level ADC as shown in the second figure?
ReplyDeleteYes, it's chip level.
ReplyDeleteI guess the question should be is it column-parallel or multiplexed. Based on tear-down reports of their 3~8Mpx sensors, multiplexed pipeline ADC are used. Not sure how scale-able it is for 16Mpx at 30fps
ReplyDeleteWhat is the advantage of using multiplexed ADC rather than column parallel? I guess power and noise are lower in the second case...
Deletemultiplexed ADC doesn't have to scale with pixel pitch since it resides outside of the array. Also, it's more accommodating to any "off-the-shelf" ADC IPs.
DeleteThis bodes well for the next years contingent of "Travel Zoom Cameras", with enhanced video capabilities. I anticipate for the European market needs, there shouldn't be any hardware limitations to use 50fps, rather than 60fps mentioned here.
ReplyDeleteThe 1/2.3-inch sensors seems commodity for the mainstream of P&S cameras, but not many of the present cameras provides raw data in addition to jpeg.
It seems that there was a typo in the blog post (active power is 310mW). The product flyer on OVT's web-site states 310mA. This sounds like a lot of power and may be a problem for DSC applications where higher power consumption unfortunately leads to a temperature increase and high hot pixels.
ReplyDeleteYou are right, thank you for the correction. Specifying mA for a dual supply device is useless and say nothing about its power. Looking at same generation OV8830, its flyer states 155mA or 291mW for a 8MP/30fps device:

The new sensors are 16MP/30fps and their current consumption is stated at 310mA. Then, I'd guess, their power is about 600mW.
Anyway, I'm removing the power statement from the post as meaningless in its current form.
so iphone5 is a 16M now?
ReplyDeleteIs "RAW scaling" a new feature in sensor products?
ReplyDelete2 MIPI 4lane,
ReplyDeletepossible??
