    Abstract: It is possible to know the mixture state in an image. With reference to image data, a region identification block (103) identifies a mixed region where a foreground object component constituting a foreground object is mixed with a background object component constituting a background object, and a non−mixed region consisting of a foreground region composed of only a foreground object and a background region composed of only a background object component. A mixture ratio calculation block (104) estimates a mixture ratio indicating a mixture ratio of the foreground object component and the background object component of a target pixel according to the ratio between the mixture region width in a predetermined direction based on the foreground object motion direction specified by the region information and the distance in a predetermined direction from the position of the target pixel to the end of the mixed region. The present invention can be applied to an image processing apparatus.

    Abstract: The present invention relates to an image processing apparatus in which a mixture ratio indicating the mixture state of a plurality of objects can be detected. A normal-equation adder 441 extracts mixed pixel data, and also extracts background pixel data corresponding to the mixed pixel data so as to generate relational expressions for the mixed pixel data and the background pixel data. A normal-equation calculator 442 detects a single mixture ratio in accordance with a predetermined number of consecutive frames based on the relational expressions. The present invention is applicable to an image processing apparatus in which a difference between a signal detected by a sensor and the real world is taken into consideration.

    Abstract: The present invention makes it possible to process at high speed the foreground component image and the background component image of picked up images on a network platform. A client computer 27 outputs information specifying image data desired to separate to a separation server 11. The separation server 11 obtains the specified image data from a storage server 18 and outputs it to a motion detecting server 12 to perform motion detection processing. Thereafter, the image data, motion vector and positional information are output to an area specifying server 13. The area specifying server 13 generates area information of the image data and outputs the area information to a mixture ratio calculating server 14 in addition to the image data, the motion vector and the positional information. The mixture ratio calculating server 14 calculates a mixture ratio on the basis of the image data, the motion vector, the positional information and the area information, and a foreground/background image separation server 15 separates foreground and background of the input image on the basis of such information. The present invention may be employed in a business model for image processing.

    Abstract: 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.
