    • Disparity in a stereoscopic image is converted, according to features of a configuration element of an image that influences depth perception of a stereoscopic image. A disparity detecting unit 110 detects disparity from a left image L and right image R of an input image, and generates a disparity map dM. A disparity correction unit 150 corrects the disparity in the disparity map dM and generates a corrected disparity map dM′. A correction feature setting unit 130 sets the correction features in the event of performing disparity correction in the disparity correction unit 150. The image synthesizing unit 160 synthesizes the left image L and right image R of the stereoscopic image based on the corrected disparity map dM′ and outputs the stereoscopic image made up of a left image L′ and right image R′ as an output image. Thus, a stereoscopic image having disparity according to the set correction features is output. The correction features therein are set according to the degree that the configuration element features such as size of disparity, position on screen, manner of special change and so forth influence the depth perception.
    • 根据影响立体图像的深度感知的图像的配置元件的特征,转换立体图像中的视差。 视差检测单元110从输入图像的左图像L和右图像R检测视差,并生成视差图dM。 视差校正单元150校正视差图dM中的视差,并产生校正的视差图dM'。 校正特征设置单元130在视差校正单元150中执行视差校正的情况下设置校正特征。图像合成单元160基于校正的视差图dM'来合成立体图像的左图像L和右图像R, 并输出由左图像L'和右图像R'构成的立体图像作为输出图像。 因此,输出根据设定的校正特征具有视差的立体图像。 其中的校正特征根据配置元件的特征如视差大小,屏幕上的位置,特殊变化的方式等的深度感知的程度来设定。
