In accordance with the present invention, a mixture ratio indicating the state of mixture of a plurality of objects such as a background image and the image of an object is detected. A pixel value setter 502 extracts background pixel data while also extracting the date of a target pixel and a pixel in the vicinity of the target pixel. The pixel value setter 502 generates a plurality of relational equations indicating data of the target pixel and the pixel in the vicinity of the target pixel and the background pixel data. An arithmetic unit 503 calculates a mixture ratio indicating a mixed state of the plurality of objects in the real world with respect to the target pixel based on the relational equations. The present invention is applicable to an image processing apparatus that accounts for a difference between a signal detected by a sensor and the real world.

L'invention porte sur un dispositif de traitement d'images pouvant déterminer un rapport de mélange indiquant l'état de mélange de différents objets tels que des images d'arrière plan et des images d'éléments mobiles. Un additionneur (502) extrait non seulement les données des pixels d'arrière plan, mais aussi les données de pixels d'intérêt et des pixels contigus. L'additionneur (502) établit plusieurs relations entre les pixels d'intérêt, les données des pixels contigus, et les données des pixels d'arrière plan. Une unité arithmétique (503) calcule le rapport de mélange indiquant l'état de mélange des objets dans le monde réel par rapport aux pixels notés en utilisant la relation. Dans ce dispositif la différence entre le signal d'un détecteur et le monde réel est prise en considération.
