Yahoo: Omnivision combines all its technologies in the new 1/4" 5MP sensor based on 1.4um BSI pixels. The new OV5642 uses TrueFocus EDOF ISP with all camera functions integrated, including anti-shake engine for image stabilization, thumbnailing support and Scalado tagging for faster image preview and zoom.
Surprisingly, the new sensor also features an embedded AF controller (EDOF not enough?). The AF mechanism can be controlled via the general purpose I/O (no AF motor driver on chip?).
Omnivision keeps mum on its BSI pixel performance figures, other than saying that the pixel sensitivity is better than 500mV/Lux-sec.
The OV5642 can output video in full resolution at 15fps. It also supports 720p HD 60fps and 1080p HD video at 30fps. The OV5642 also offers Bridging and Daisy Chain support, which allow secondary cameras to share the use of its ISP via the digital video port (DVP), while providing continued output through the dual-lane MIPI interface.
The OV5642 will be available for sampling in the coming weeks, and is expected to go into volume production in the first quarter of 2009.
"EDOF not enough?" - Not their EDoF. It is limited in the additional depth of focus it provides.
ReplyDeleteSo, does their EDOF have a "back door" to get focusing info for AF algorithm? Somehow they should provide a way to work with both of them at the same time.
ReplyDeleteI would assume one does not support the other. Simply they are supporting both configurations: Fix focus+EDoF, and AF.
