What is a RYYB sensor?
RYYB is also an abbreviation of English, which refers to two yellow pixels (Y) instead of two green pixels (G) to form a RYYB sensor.
Replace green with yellow, and we know that yellow is a combination of green and red, a superposition of both in terms of brightness, then finally
The light loss problem can be significantly reduced, and the light intake can be increased by about 40%.
The RYYB sensor technology is outstanding on Huawei’s mobile phone P30Pro, with ISO as high as 409600, which makes the mobile phone “take night as day”, and Huawei Mate70Pro+ continues to use the technology.
Benefits of RYYB sensors
1. Improve color reproduction
By adding yellow and red filters, the RYYB sensor can more accurately capture yellow and red light that is difficult for the human eye to perceive, thereby restoring richer colors in photos, improving the accuracy and realism of color reproduction.
2. Optimize performance in low light environments
In low light environments, the RYYB sensor is able to capture more light due to the role of yellow and red filters, reducing noise and improving picture detail, thus obtaining clearer and brighter image effects in low light environments.
3. Enhance dynamic range
While improving color reproduction and reducing noise, the RYYB sensor can also enhance dynamic range, so that the details of the light and dark parts of the photo can be better preserved in the scene with high contrast.
Applied to monitor changes in the industry
If RYYB sensors are used in the monitoring industry, it may bring changes in the following aspects:
1. Enhanced night vision: The RYYB sensor can theoretically increase light intake by 40% by replacing the green filter in the traditional RGGB arrangement with a yellow filter. This means that in low light environments, the surveillance camera can capture more light, thereby improving the brightness and detail of the image, making the surveillance video clearer at night or in low light conditions.
2. Color reproduction challenge: Although the RYYB sensor has a significant improvement in the amount of light input, it also brings color reproduction challenges. Because the yellow filter filters through both red and green light, it may cause excessive red light, causing color distortion. Therefore, surveillance camera manufacturers need to fine-tune the image through algorithms to ensure the accuracy of color reproduction.
3. Increased monitoring range: Due to the excellent performance of RYYB sensors in low-light environments, the effective monitoring range of surveillance cameras may be expanded, especially at night or in areas with poor lighting conditions. This has important implications for areas such as security monitoring and intelligent transportation systems.
4. Improved image quality: The application of RYYB sensors may improve the overall quality of monitoring images, including sharpness, dynamic range and color reproduction. This is an important advance for intelligent surveillance technologies such as video analysis and facial recognition.
5. Cost effectiveness: If the production cost of RYYB sensors can be controlled within a reasonable range, it may become the first choice for surveillance camera manufacturers, thereby reducing the overall cost of monitoring systems while improving performance.
6. Algorithm optimization needs: In order to take full advantage of RYYB sensors, surveillance camera manufacturers and solution providers need to continuously optimize image processing algorithms to adapt to the characteristics of RYYB sensors and solve problems such as color reproduction.
Taken together, the application of RYYB sensors may bring clearer night surveillance images, expanded surveillance coverage, improved image quality, and possibly cost effectiveness to the surveillance industry. However, this also requires surveillance camera manufacturers and solution providers to continuously optimize algorithms to solve technical challenges such as color reproduction.
