The PureCel®-S OV21840 is part of OmniVision's family of high performance 21-megapixel image sensors designed to bring DSC-like images and video to the next generation of flagship smartphones. The OV21840 captures stunning ultra-high resolution images and video while enabling next-generation digital imaging features.

The sensor utilizes OmniVision's new stacked die technology which separates the imaging array from the image sensor processing pipeline into a stacked die structure. This enables additional sensor functionality, such as phase detection autofocus (PDAF), two-dimensional contrast fast autofocus and high dynamic range (HDR) video, while maintaining a much smaller footprint.

The 1/2.4-inch OV21840 supports an active array of 5344 x 4016 pixels (21.4-megapixels) operating at 27 frames per second (fps), enabling ultra-high definition burst photography.

The sensor is capable of recording quad high definition (QHD) video at 30 fps in HDR mode to enable 'always on' HDR preview mode. Lastly, the sensor supports 720p high definition (HD) video at 120 fps, and 1080p HD video at 90 fps for crisp, slow motion video recording.

The OV21840 fits into a 10.5 x 10.5 mm module with a z-height of 6 mm.
