Abstract

La presente invención proporciona un método de procesamiento de imágenes. Un área objetivo y un área de fondo se determinan en una imagen realizando una segmentación de máscara en la imagen. Se aplican diferentes modos de procesamiento de color al área objetivo y al área de fondo, de modo que la luminancia del área objetivo es mayor que la luminancia del área de fondo, o la crominancia del área objetivo es mayor que la crominancia del área de fondo y un objeto principal correspondiente al área objetivo se destaca de forma más prominente. Esto permite que un usuario de terminal tenga un efecto especial de película durante la fotografía o la fotografía de vídeo, y mejora la experiencia fotográfica del usuario. Además, la presente invención proporciona además un método de eliminación de parpadeo, de modo que un cambio de color del contenido de vídeo sea más suave y más natural.
