Title:
COLOR TEMPERATURE MEASUREMENT METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/067041
Kind Code:
A1
Abstract:
Provided in the present application are a color temperature measurement method and apparatus, and an electronic device, which can accurately measure the color temperature of a light source. The method comprises: according to multi-channel data of a light source to be subjected to measurement and multi-channel data of a first standard light-source group, determining a proportionality coefficient corresponding to the first standard light-source group, wherein the proportionality coefficient corresponding to the first standard light-source group is used for representing the proportion of multi-channel data of each standard light source in the first standard light-source group to the multi-channel data of the light source to be subjected to measurement; according to the multi-channel data of the first standard light-source group and the proportionality coefficient corresponding to the first standard light-source group, determining a tristimulus value of the light source to be subjected to measurement; and determining, according to the tristimulus value, the color temperature of the light source to be subjected to measurement.
