Abstract

Generar una señal de imagen comprende un receptor (401) que recibe imágenes fuente que representan una escena. Un generador de imágenes combinadas (403) genera imágenes combinadas a partir de las imágenes fuente. Cada imagen combinada se deriva solo de partes de al menos dos imágenes de las imágenes fuente. Un evaluador (405) determina medidas de calidad de predicción para elementos de las imágenes fuente donde la medida de calidad de predicción para un elemento de una primera imagen fuente es indicativa de una diferencia entre valores de píxel en la primera imagen fuente y valores de píxel predichos para píxeles en el elemento. Los valores de píxel predichos son valores de píxel que resultan de la predicción de píxeles de las imágenes combinadas. Un determinador (407) determina segmentos de las imágenes fuente que comprenden elementos para los cuales la medida de calidad de predicción es indicativa de una diferencia por encima de un umbral. Un generador de señal de imagen (409) genera una señal de imagen que comprende datos de imágenes que representan las imágenes combinadas y los segmentos de las imágenes fuente.
