    摘要： 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.

    摘要： The present invention relates to an image processing device enabling detection of a mixture ratio indicating the state of mixture between multiple objects. A contour region information generating unit 421 and a normal equation generating unit 422 extracts contour region pixel data within a frame of interest positioned at a contour region with approximately a same mixture ratio, extracts corresponding pixel data from a frame different to the frame of interest, extracting background pixel data corresponding to the contour region pixel data or the corresponding pixel data, and generating an equation wherein the mixture ratio is an unknown number, based on region specifying information specifying a non-mixed region made up of a foreground region and background region and a mixed region. A least square approximation unit 423 detects the mixture ratio by solving the equation. The present invention can be applied to signals processing devices for processing image signals.

    摘要： 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.
