Abstract
La presente descripción revela un método y un dispositivo de ajuste de color, y pertenece a un campo de los gráficos de computadora. El método de ajuste de color comprende: obtener datos de fotograma provenientes de una memoria de almacenamiento temporal de fotogramas; convertir los datos de fotograma de un espacio de color original a un espacio de color lineal original mediante un proceso de corrección de-gamma, a fin de obtener datos de fotograma en el espacio de color lineal original; convertir los datos de fotograma del espacio de color lineal original a un espacio de color lineal de destino, a fin de obtener datos de fotograma en el espacio de color lineal de destino; y aplicar una corrección gamma a los datos de fotograma del espacio de color lineal de destino usando un coeficiente gamma de destino, a fin de obtener datos de fotograma en un espacio de color de destino. En la presente descripción, al aplicar el proceso de corrección de-gamma a los datos de fotograma provenientes de la memoria de almacenamiento temporal de fotogramas, convertir al espacio de color lineal de destino los datos de fotograma corregidos con la corrección de-gamma, y aplicar la corrección gamma a los datos de fotograma del espacio de color lineal de destino a fin de obtener los datos de fotograma en el espacio de color de destino, se soluciona el problema que consiste en observar efectos de visualización variables de los mismos datos de fotograma en diferentes dispositivos, y se consigue el efecto de visualización constante de los mismos datos de fotograma en diferentes dispositivos.
