Abstract: An object of the present invention is to make it possible to detect the mixture state of an image. An area specifying unit 103 specifies, in correspondence with image data, a mixed area in which foreground object components forming a foreground object and background object components forming a background object are mixed and a non-mixed area formed of a foreground area consisting of only the foreground object components and a background area consisting of only the background object components. A mixture-ratio calculator 104 estimates, based on the ratio of the width of the mixed area in a predetermined direction with respect to the moving direction of the foreground object, the width of the mixed area being specified by the area information, to the distance from the position of a designated pixel to the edge of the mixed area in the predetermined direction, the mixture ratio indicating the ratio of the foreground object components and the background object components of the designated pixel.

Abstract: An object of the present invention is to make it possible to generate a three-dimensional image from a two-dimensional image in accordance with the mixture state of images. A foreground/background component image generator 91 generates, from image data including a foreground area consisting of only foreground object components, a background area consisting of only background object components, and a mixed area in which the foreground object components and the background object components are mixed, a foreground component image consisting of only the foreground object components and a background component image consisting of only the background object components. A foreground-parallax-image generator 93 generates a right-eye foreground parallax image by adding the parallax to the foreground component image, and also generates a left-eye foreground parallax image by adding the parallax to the foreground component image.

Abstract: An object of the present invention is to make it possible to detect an area in which mixture occurs. An object extracting unit 251 extracts a foreground object from an input image to generate an area-specified object which is formed of a foreground image object and a value indicating that the object belongs to a background area. A motion compensator 252 compensates for the motion of the area-specified object based on the supplied motion vector and positional information thereof. A subtracting unit 254 subtracts the pixel value of a pixel belonging to a foreground area of the area-specified object in frame #n−1 supplied from frame memory 253 from the pixel value of a pixel belonging to a foreground area of the area-specified object in frame #n supplied from the object extracting unit 251, in which the pixels are at the corresponding position, so as to obtain a frame difference between the pixels belonging to the foreground area.

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.

Abstract: The present invention allows detection of an exposure time of an image that has already been captured. A motion detector 102 detects an amount of inter-frame movement of a foreground object in a designated frame based on the designated frame and a frame preceding or subsequent to the designated frame. A mixture-ratio calculator 104 detects a mixture ratio indicating the ratio of mixture of a foreground component and a background component in a mixed area of the designated frame. In accordance with the mixture ratio, the mixture-ratio calculator 104 detects the amount of movement of the foreground object within an exposure time in which pixel data is obtained. A shutter-time calculator 106 detects a ratio of a time interval between frames to the exposure time based on the amount of inter-frame movement and the amount of movement within the exposure time of the foreground object. The present invention is applicable to an image processing apparatus.

Abstract: The present invention aims to recognize the mixture state of images. An area specifying unit 103 specifies a mixed area in which foreground object components which form a foreground object and background object components which form a background object are mixed. An estimated-mixture-ratio calculator 104 detects, in correspondence with the image data, the mixture ratio indicating the ratio of the mixture of the foreground object components to the mixture of the background object components in the mixed area in which the foreground object components and the background object components are mixed. At least one of the area specifying unit 103 and the estimated-mixture-ratio calculator 104 performs image processing on the basis of a plurality of types of components.

Abstract: The present invention allows an image to be processed corresponding to the mixture of a background image and an image of a moving object. A region specifying unit specifies a mixed region wherein foreground object components making up foreground objects and background object components making up background objects are mixed, and a non-mixed region configured of one of foreground object components making up foreground objects or background object components making up background objects, and outputs region information corresponding to the results of specifying.

An area specifying unit 103 specifies a non-mixed area formed of a foreground area consisting of foreground object components which form a foreground object and a background area consisting of background object components which form a background object, or a mixed area in which the foreground object components and the background object components are mixed. A separating/blur-eliminating unit 1503 simultaneously performs processing for separating the foreground object components and the background object components from the pixel data of the mixed area and processing for eliminating motion blur from the separated foreground object components based on a result obtained by specifying the area. The present invention is applicable to an image processing apparatus in which a difference between a signal detected by an image-capturing device and the real world is considered.
