  • Patent number: 7477761
    Abstract: An apparatus and method for separating a background image and an object image. The apparatus comprises an area specifying unit for specifying areas of the image. The area specifying unit specifies, in a first period-of time, an uncovered background area in which foreground object components and background object components are mixed. The area specifying unit specifies, in a second period of time, a foreground area consisting of only the foreground object components and a background area consisting of only the background object components. The area specifying unit specifies, in a third period of time, a covered background area in which the foreground object components and the background object components are mixed. A mixture-ratio calculator detects a mixture ratio indicating a ratio of the foreground object components and the background object components. A separator separates the pixel data into the foreground object components and the background object components based on the mixture ratio.

  • Patent number: 7477289
    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.

  • Patent number: 7447378
    Abstract: The present invention enables processing results which are more accurate and which have higher precision as to events of the real world to be obtained. (An inverse gamma correction unit 5001 applies inverse gamma correction to an input image wherein light signals of the actual world have been projected and a part of the continuity of the light signals of the actual world has been lost, and which has been subjected to gamma correction. A data continuity detecting unit 101 detects, in the input image subjected to inverse gamma correction, data continuity corresponding to the continuity of light signals of the real world. An actual world estimating unit 102 estimates the light signals by estimating the continuity of the light signals of the real world, based on the data continuity. An image generating unit 103 generates an output image from the estimated light signals.

    Abstract: A motion-vector-setting section (31) sets a first motion vector in units of pixel in a target image. An exposure-time-ratio-setting section (32) sets in units of image an exposure time ratio that is a ratio between a time interval of the target image and a period of exposure time. A motion-blur-amount-setting section (33) sets a motion blur amount in units of pixel based on the exposure time ratio and the first motion vector. Based on the motion amount, a processing-region-setting section (36) sets processing regions as well as a processing-coefficient-setting section (37) sets processing coefficients. A pixel-value-generating section (38) generates pixel values that correspond to the target pixel from pixel values in the processing region and the processing coefficients. A motion-blur-adding section (41) adds a motion blur to an image containing the pixel value generated based on an input second motion vector and the first motion vector.
