    Abstract: The present invention takes into consideration the real world where data was acquired, and enables obtaining of processing results which are more accurate and more precise as to phenomena in the real world. A data continuity detecting unit 101 detects the continuity of data of second signals, having second dimensions that are fewer than first dimensions had by first signals which are real world signals and are projected whereby a part of the continuity of the real world signals is lost, wherein the continuity to be detected corresponds to the continuity of the real world signals that has been lost. An actual world estimating unit 102 estimates a real world image by estimating the continuity of the real world image that has been lost, based on the continuity of the data detected by the data continuity detecting unit 101.

    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.

    Abstract: 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.

    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: An image processing device capable of determining a mixing ratio indicating the state in which a plurality of objects such as a background image and an image of a moving object are mixed. An addition unit (502) extracts not only the background pixel data but also data on a pixel of interest and its adjacent pixels. The addition unit (502) generates a plurality of relations among the pixel of interest, the adjacent pixel data, and the background pix el data. An arithmetic unit (503) computes the mixing ratio indicating the mixe d state of the objects in the real world with respect to the noted pixel by using the relation. This an image processing device in which the difference between the signals produced by a sensor and the real world is taken into consideration is provided.
