Abstract

Un método y aparato de corrección del balance de blancos, un dispositivo y un medio de almacenamiento. El método de corrección del balance de blancos comprende: introducir la imagen a corregir en un modelo de puntos de aberración no cromática preentrenado para obtener un mapa de ponderación de puntos de aberración no cromática de la imagen a corregir (101); determinar, según el mapa de ponderación de puntos de aberración no cromática, un parámetro de color de iluminación de la imagen a corregir (102); y, según el parámetro de color de iluminación, realizar la corrección del balance de blancos en la imagen a corregir para obtener una imagen corregida (103).
