Pixel binning is a technology used to prevent possible image noise in low light conditions
Pixel binning: technology explained
Pixel binning is a photography technology that is primarily used in cameras with small sensors, such as smartphones.
- The sensor size has a significant effect on the amount of light that can be captured by the camera. As the available pixels are smaller, not as much light is captured, which in turn can lead to image noise.
- This problem is prevented with pixel binning. With this technology, groups of smaller pixels are combined into larger ones to increase the amount of light available during recording. This even works in poor lighting conditions.
- Algorithms are used to combine the image information of the individual pixels in order to produce a high-quality end result. These algorithms for pixel binning are constantly being optimized, especially in modern smartphones.
- In good lighting conditions, the technology is generally not required, even with small sensors. The algorithms regulate the pixel fusion in the event of possible light changes.
- The only disadvantage is the downsizing of the resolution due to pixel merging. If, for example, four pixels are combined to form a larger one, the resolution is reduced accordingly.
