OmniVision Outs Two Sensors With Phase-detection Autofocus

By 09:31 Thu, 22 Jul 2021 Comments



It's a day for sensors it seems – first Sony and now OmniVision has chimed in with two recent sensors. Like Sony's sensor, the OmniVision sensors utilize a stacked design (with a brand name of PureCel-S). Both sensors measure about the same and one is 23.8MP, the other 21.4MP and both record the same video.

The two sensors feature phase-detection autofocus in addition to the regular contrast autofocus. The modules measure 10.5x10.5mm and are about 6mm tall, the higher res module is slightly taller at 6.3mm.

The OmniVision OV23850 is a 1/2.3" sensor with 23.8MP resolution. It can output 5,632 x 4,224px photos at 24fps. The other sensor, OmniVision OV21840, is 1/2.4" gigantic and outputs 21.8MP (5,344 x 4,016px) photos at 27fps.

The two have the same video recording skills – QHD at 30fps or 1080p at up to 90fps. For an even higher frame rate there's 720p@120fps. The 23.8MP sensor is also capable of 4.5MP video at 60fps, which is slightly above QHD but nowhere near the 8.3MP that is 2160p video.

Samples of the two sensors are currently available for sampling with mass production expected to start in the first three months of next year.
