从集成图像显示时再现的空间光学分布着手，研究了微透镜参数、记录/显示平面分辨率和成像系统空间分辨率的关系。研究结果表明成像系统的空间分辨率与微透镜的孔径和焦距大小有关。采用较小尺寸的微透镜，有助于提高成像系统的空间分辨率，但对记录/显示平面分辨率的要求随微透镜尺寸的减小以及物点深度的增加而提高。研究结果可用于集成成像系统的优化设计。

Changing illumination condition can change the result of image segmentation algorithm and reduce the intelligent recognition rate. A novel color image segmentation method robust to illumination variations is presented. The method is applied to the skin segmentation. Based on the hue preserving algorithm, the method reduces the dimensionality of the red-green-blue (RGB) space to one dimension, while keeping the hue of every pixel unchanging before and after space transformation. In the new color space, the skin color model is established using Gaussian model. Experimental results show that the method is robust to illumination variations, and has low computational complexity.
