Why is the optical sensing accuracy of the REDMI Note 14 low?
The low optical sensing accuracy in the REDMI Note 14 is due to the significant difference in spectral distribution between the blue phenanthrene light source and the standard light source used by the phone. This mismatch affects the sensitivity of the Ambient Light Sensor (ALS) channel, resulting in inaccuracies in the final light measurement.
For your reference, the detailed explanation is as follows:
1. The blue phenanthrene light source used in the REDMI Note 14 differs greatly from standard light sources, which causes varying sensitivity levels in the ALS channel;
2. Blue light sources are artificial and are primarily used in specialized applications like medical equipment, rather than in everyday light sensing scenarios;
3. The perceived accuracy of the light sensing also varies depending on your sensitivity to different types of light sources, influencing the overall performance. The development team is working on optimizing this feature for better accuracy.
