    • The present invention makes it possible to adaptively convert distribution of disparities or depths of a stereoscopic image according to a visual property of a human related to stereopsis. A stereoscopic image processing apparatus according to the present invention is a stereoscopic image processing apparatus which receives an input stereoscopic image, and converts distribution of disparities or depths of the input stereoscopic image, the apparatus includes a planar region extracting unit (31) which extracts a planar region in the stereoscopic image; a non-planar region conversion processing unit (exemplified using non-planar region disparity conversion processing unit (32)) which performs a first conversion process in which the disparity or the depth is converted with respect to a non-planar region which is a region other than the planar region; and a planar region conversion processing unit (exemplified using planar region disparity conversion processing unit (33)) which performs a second conversion process in which the disparity or the depth is converted using a conversion property which is different from that in the first conversion process with respect to the planar region. Here, the first conversion process is a process in which a conversion based on a non-linear conversion property is performed related to the disparity or the depth with respect to the non-planar region.
    • 本发明使得可以根据与立体视觉相关的人的视觉特性来自适应地转换立体图像的不同或深度的分布。 根据本发明的立体图像处理装置是立体图像处理装置,其接收输入立体图像,并且转换输入的立体图像的差异或深度的分布,该装置包括平面区域提取单元(31),其提取 立体图像中的平面区域; 非平面区域转换处理单元(使用非平面区域视差转换处理单元(例如,使用非平面区域视差转换处理单元(32)示例)),其执行第一转换处理,其中视差或深度相对于作为区域的非平面区域被转换 除了平面区域; 以及平面区域转换处理单元(使用平面区域视差转换处理单元(33)示例)),其执行使用与第一转换处理中不同的转换属性来转换视差或深度的第二转换处理, 相对于平面区域。 这里,第一转换处理是基于与非平面区域的视差或深度相关的基于非线性转换特性的转换的处理。
