Abstract

The embodiment of the invention discloses a color temperature sensor calibration method and a related device. In the color temperature sensor calibration method, after using the calculated color temperature error to correct the noise floor of the color temperature sensor, use the color temperature sensor after the noise floor correction to test the color temperature values ​​of P standard light sources to obtain P test color temperature values, and use P test color temperature values ​​and standard color temperature values ​​of P standard light sources deduce the functional relationship y=f(x) between the test color temperature value and the standard color temperature value, and the functional relationship y=f(x) is used to correct the shooting terminal The color temperature value detected by the color temperature sensor during the shooting process of the shooting terminal, the technical solution provided by the embodiment of the present invention is beneficial to realize better and scientific calibration of the color temperature sensor of the shooting terminal.

Description

technical field [0001] The present invention relates to the technical field of camera and photographing, in particular to a color temperature sensor calibration method and a related device. Background technique [0002] Shooting terminals such as mobile phones, tablet phones, and digital cameras have become people's daily necessities, and the functions of the shooting terminals are becoming more and more powerful. Users often need to use the shooting terminals to take pictures (such as taking photos or videos) in life and work. [0003] The color temperature sensor in the shooting terminal is used to assist shooting, so the accuracy of the color temperature test of the color temperature sensor has a great impact on the shooting quality, but factors such as the structure and material of the color temperature sensor may affect the color temperature test accuracy of the color temperature sensor. As users continuously improve the shooting quality, it becomes necessary to calibra...
