摘要 |
It is possible to detect a mixture ratio indicating a mixture state of a plurality of objects such as a background image and an image of a moving object. A normal equation addition block (541) extracts mixed pixel data in accordance with a motion and extracts background pixel data in accordance with the mixed pixel data, thereby generating a plurality of relationship equations for a target pixel. A normal equation calculation block (542) detects a mixture ratio indicating a mixture state of the object in accordance with the relationship equation. The normal equation addition block generates a number of relationship equations by a first approximation assuming that the foreground object component changes approximately rectilinearly and by a second approximation assuming that the mixture ratio changes approximately rectilinearly. |
