    • A region of a background image, a region of a moving object image, and a region having a mixed image are identified. A mixture ratio calculation block (103) extracts pixel data of peripheral portion of a frame around the target pixel of the target frame of image data as a background pixel data corresponding to a background object, extracts the target pixel data of the target pixel contained in the target frame, generates a plurality of relationship equations indicating the relationship between the target pixel data and the background pixel data, and calculates a mixture ratio of the mixture state of the object according to the relationship equations. A region identification block (104) substitutes the calculated mixture ratio in the relationship equations, calculates a predicted error, and identifies the region to which the target pixel belongs as a covered background region, an uncovered background region, a foreground region, or a background region. The present invention can be applied to an image processing apparatus.
    • 识别背景图像的区域,运动对象图像的区域和具有混合图像的区域。 混合比率计算块(103)提取图像数据的目标帧的目标像素周围的帧的周围部分的像素数据作为与背景对象相对应的背景像素数据,提取包含在目标像素中的目标像素的目标像素数据 目标帧产生指示目标像素数据和背景像素数据之间的关系的多个关系式,并根据关系式计算对象的混合状态的混合比。 区域识别块(104)代替关系式中的计算出的混合比例,计算出预测误差,并将目标像素所属的区域识别为被覆盖的背景区域,未覆盖的背景区域,前景区域或背景 地区。 本发明可以应用于图像处理装置。

    • A motion amount indicating movement of an object during an exposure time can be obtained. An estimated mixture ratio processing block, performs calculation corresponding to a model of a covered background region so as to calculate an estimated mixture ratio for each pixel and an estimated motion vector and supplies the estimated mixture ratio and the estimated motion vector which have been calculated to a mixture ratio determination block. An estimated mixture ratio processing block (402) performs a calculation corresponding to a model of an uncovered background region so as to calculate an estimated mixture ratio for each pixel and a motion vector and supplies the estimated mixture ratio and the estimated motion vector which have been calculated to the mixture ratio determination block (403). The mixture ratio determination block (403) sets a mixture ratio and a motion vector in accordance with region information indicating to which of the foreground region, the background region, the covered background region, and the uncovered background region, a pixel belongs. The present invention can be applied to an image processing apparatus.
    • 可以获得指示在曝光时间期间物体的移动的运动量。 估计混合比处理块,进行与覆盖背景区域的模型对应的计算,以计算每个像素的估计混合比和估计的运动矢量,并将估计的混合比和估计的运动矢量提供给 混合比确定块。 估计混合比处理块(402)执行与未覆盖的背景区域的模型相对应的计算,以计算每个像素的估计混合比和运动矢量,并将所估计的混合比和所估计的运动矢量 根据混合比确定块(403)计算。 混合比确定块(403)根据表示像素所属的前景区域,背景区域,被覆盖的背景区域和未覆盖的背景区域中的哪一个的区域信息来设置混合比率和运动矢量。 本发明可以应用于图像处理装置。
