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 (541) generates a plurality 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. The present invention can be applied to a signal processing apparatus which processes an image.

摘要： An image processing apparatus capable of coping with mixture of a background image and a moving object image. A region identification block (103) identifies a mixed region where a foreground object component and a background object component are mixed and a non-mixed region where only one of the foreground region and the background region is present, and outputs region information in accordance with the identification result. A foreground separation block (105) separates the input image into a foreground component image and a background component image in accordance with the region information. A separated image processing block (106) processes the foreground component image and the background component image separately in accordance with the separation result. The present invention can be applied to an image processing apparatus.

摘要： It is possible to know a mixture state of an image. A region identification block (103) identifies a mixed region of image data where a foreground object component constituting a foreground object is mixed with a background object component constituting a background object. According to the image data, a mixture ratio calculation block (104) identifies a mixed region where a foreground object component constituting a foreground object is mixed with a background object component constituting a background object. With reference to the image data, the mixture ratio calculation block (104) calculates a mixture ratio indicating a mixture ratio of the foreground object component and the background object component in the mixed region where the foreground object component is mixed with the background object component. At least one of the region identification block (103) and the mixture ratio calculation block (104) performs image processing according to a plurality of types of components. The present invention can be applied to an image processing apparatus.
