50MP image sensor with DCG technology
Author: EIS Release Date: Jan 14, 2023
In April, OMNIVISION intends to sample a 50MP image sensor with a dual conversion gain (DCG) technology.
The chip’s 1.2µm pixel in a 1/1.3-inch optical format, is designed for high-end smartphone rear-facing cameras.
Designated OV50H, the device offers low-light and autofocus performance, supports 12.5 MP at 120 fps and high dynamic range (HDR) at 60 fps.
It is OMNIVISION’s first sensor to feature horizontal/vertical (H/V) quad phase detection (QPD).
The OV50H is built on OMNIVISION’s PureCel Plus-S stacked-die technology for best-in-class image sensor performance.
It features OMNIVISION’s first H/V QPD autofocus technology. QPD enables 2×2 phase detection autofocus (PDAF) across the sensor’s entire image array, and H/V mode ensures that both horizontal and vertical orientations are in the same frame with 100% coverage.
This feature improves distance calculation, provides faster autofocus and enhances low-light performance.
In combination with on-chip remosaic for the QPD color filter array, the result is premium image quality for the wide and ultrawide rear-facing cameras in flagship and high-end smartphones.
Key Features of the OV50H:
· 4-cell binning enables 12.5M mode for video and preview with 2.4µm equivalent sensitivity for excellent low-light performance; supports up to 120fps with 4x low-light sensitivity
· 8K video with on-chip remosaic; 4K + EIS at 120fps linear and 60fps HDR
· DCG HDR with on-chip combination and staggered HDR support for flexibility of different HDR modes depending on scene; supports staggered HDR in crop zoom mode
· Capability to achieve 12.5M at 30fps HDR with 100+dB dynamic range when using DCG + very short staggered exposure HDR or 3-exp staggered HDR
· H/V QPD support for best-in-class autofocus
· Full 50MP Bayer output and 2x crop zoom functionality
Samples of the OV50H will be available in April 2023.
