Abstract
La presente descripción se refiere a un aparato de procesamiento de imágenes y a un método de procesamiento de imágenes para permitir la supresión de un aumento en la capacidad de memoria requerida para la transformación ortogonal y la transformación ortogonal inversa. Se deriva una matriz de transformación utilizando una submatriz que configura una parte de la matriz de transformación, un residuo de predicción de una imagen se transforma ortogonalmente utilizando la matriz de transformación derivada, y los datos de coeficientes obtenidos mediante la transformación ortogonal del residuo de predicción se codifican para generar un flujo de bits. La presente divulgación se puede aplicar, por ejemplo, a un aparato de procesamiento de imágenes, un dispositivo de codificación de imágenes, un dispositivo de decodificación de imágenes o similares.
