Announcement
On September 12, Sony Semiconductor announced that its LYTIA image sensor brand is collaborating with OPPO. The LYTIA sensor will be paired with OPPO's Ultra Light and Shadow image engine to deliver an image sensor that uses dual-transistor pixel technology.
Background
The dual-transistor pixel concept is not new. Sony first introduced the technology in 2021 and deployed it this year in the Sony Xperia 1 V flagship smartphone.
How dual-transistor pixels work
The dual-transistor pixel structure places a photodiode in the first layer and a pixel transistor in the second layer. The two layers work together to capture more light and reduce image noise. This architecture helps avoid underexposure and overexposure in scenes that combine bright and dark regions, such as backlit environments, and can produce high-quality, low-noise images in low-light conditions.
Implications for OPPO devices
The collaboration suggests that upcoming OPPO models may adopt a LYTIA sensor for their primary camera, which could improve imaging performance.
Notably, OPPO previously developed an imaging NPU called Mariana X. Following the termination of the internal chip effort at Zheku, OPPO appears to be partnering with other vendors for imaging components.
Leaked specifications
Leaker WHYLAB reported that the OPPO Find N3 main camera will debut the LYTIA sensor LYT800, sized 1/1.43" with 53MP. The specifications are said to be similar to the IMX888. There are also reports that the vivo X100 series may use the same sensor.
