In order to estimate a posture with greater stability and higher accuracy, a posture optimization unit optimizes joint positions, angles, the number of joints, etc., that are the posture parameters ofa human model (tree structure) by a plurality of optimization techniques so that these parameters match an area where a human body can possibly exist, the plurality of optimization techniques being switched to an optimum one for use. The optimization techniques include the steps of: 1: an initial value, 2: an algorithm, and 3: a constraint, and optimization is achieved by switching each of thesethree. The image processing device and method can be applied to, for example, an image processing device for optimizing the joint positions and angles of a human model. 为了以更大的稳定性和更高度的精度估计姿势。姿势优化单元通过多种优化技术来优化作为人模型(树结构)的姿势参数的关节位置、角度、关节数量等，从而使得这些参数匹配人体可能存在的区域，所述多种优化技术被切换到最优技术以供使用。优化技术包括1：初始值，2：算法和3：限制，并通过切换这三者中的每个来实现优化。例如，能够将本公开应用于优化人体模型的关节位置和角度的图像处理装置。
