Omnivision Introduces a New Mobile Device

Omnivision, a company that makes semiconductor products, released the OV50K40, the first image sensor for smartphones to use TheiaCel technology


TheiaCel technology uses lateral overflow integration capacitors (LOFIC) to give you single-exposure HDR, no matter what the lighting is like.

This 50-megapixel (MP) image sensor is built on TheiaCel and has a 1.2-micron (µm) pixel in a 1/1.3-inch optical format. It has high gain and correlated multiple sampling (CMS) for the best performance in low-light situations.

“People have had enough of the low quality photos and videos that come with modern cell phones. This is especially true for pictures taken at sunrise or sunset or at night with bright lights in the background.” “But with our new TheiaCel technology, Omnivision has shaken up the cell phone business today,” said Arun Jayaseelan, senior product marketing manager at Omnivision.

Four-cell binning lets the OV50K40 shoot 12MP photos at 120 frames per second (fps) and 60fps with HDR. It also has 4x sensitivity for top-notch low-light performance.


For one hundred percent coverage, quad phase detection (QPD) enables 2×2 phase detection autofocus (PDAF) across the entire image array of the sensor.

A re-mosaic of the on-chip QPD enables a 50MP Bayer output in its entirety, 8K video, and twice the crop-zoom functionality.

Built upon Omnivision’s PureCel Plus-S stacked-die technology, the OV50K40 features 1.2m pixels and a high resolution.

It has now entered the phase of industrial production.
