    • PROBLEM TO BE SOLVED: To provide an apparatus and method for generation of an enhanced motion compensation image and for reduction of image noise. SOLUTION: Reliability of a local motion compensation image generated by applying a local motion vector and a global motion compensation image generated by applying a global motion vector is calculated for each image area and in accordance with the calculated reliability, processing for combining a pixel value of the local motion compensation image and a pixel value of the global motion compensation image is executed to generate a blend motion compensation image. Further, a noise-reduced image is generated by processing for adding the blend motion compensation image and a reference image. The present configuration enables the blend motion compensation image constituted of the optical pixel value to be generated in accordance with the reliability of the local motion compensation image and the global motion compensation image to be generated. Moreover, a high quality image with reduced noise can be generated. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供一种用于生成增强运动补偿图像并减少图像噪声的装置和方法。 解决方案:通过应用局部运动矢量和通过应用全局运动矢量生成的全局运动补偿图像产生的局部运动补偿图像的可靠性针对每个图像区域并根据计算的可靠性被计算, 执行局部运动补偿图像的像素值和全局运动补偿图像的像素值以生成混合运动补偿图像。 此外,通过用于添加混合运动补偿图像和参考图像的处理来生成噪声降低的图像。 本配置使得能够根据要产生的局部运动补偿图像和全局运动补偿图像的可靠性来生成由光学像素值构成的混合运动补偿图像。 此外,可以产生具有降低的噪声的高质量图像。 版权所有(C)2010,JPO&INPIT
