Quad-Bayer Technology

This configuration provides better low-light performance and higher image quality. It can either provide higher resolutions or improve image quality by combining the data from four adjacent pixels.

How Quad Bayer Technology Works

The key to how Quad Bayer technology works is the special arrangement of pixels on the image sensor. In a conventional Bayer sensor, individual pixels are used to capture red, green and blue information.

In contrast, Quad Bayer technology combines four adjacent pixels that share the same color filter into a single unit. This allows for more efficient light collection and more accurate color capture.

Advantages of Quad Bayer Technology

Increased light sensitivity

One of the biggest benefits of Quad Bayer technology is increased light sensitivity. Because four pixels work as one, more light can be captured, resulting in brighter, clearer images, even in low light.

Improved image quality

By combining data from four adjacent pixels, Quad Bayer technology can significantly improve image quality. The result is sharper, more detailed photos with less noise.

Higher resolution

Another benefit is the ability to achieve higher resolution. In well-lit scenarios, the four pixels can be used separately to utilize the full resolution of the sensor, resulting in extremely detailed images.

Applications of Quad Bayer Technology

Quad Bayer technology is used in a wide range of devices, from smartphones to professional digital cameras. Many modern smartphones use this technology to maximize the performance of their cameras and provide users with the best possible image quality.
