Abstract

The embodiment of the invention discloses a color temperature sensor calibration method and a related device. According to the color temperature sensor calibration method, after the base noises of a color temperature sensor are calibrated by utilizing calculated color temperature errors, the color temperature values of P standard light sources are tested by utilizing the color temperature sensor with calibrated base noises, thus obtaining P test color temperature values; the function relationship y=f(x) between the test color temperatures and the standard color temperatures is derived by utilizing the P test color temperature values and the standard color temperature values of the P standard light sources; and the function relationship y=f(x) is used for calibrating the color temperature value of the color temperature sensor of a photographing terminal detected in the photographing process of the photographing terminal. The technical solution provided by the embodiment of the invention is beneficial for carrying out relatively excellent and scientific calibration to the color temperature sensor of the photographing 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...
