Integration of multiple images taken by systematically varying a camera parameter (e.g.iris, focus, shutter speed, view direction and so on) allows us to extract the reliable scence information which cannot or hardly be obtained from a single image. In this study, we developer high precision versatile camera systems based on this idea. The results of the study can be summarized as follow :1.Development of a computer controlable lens system whose iris, focus, and zoom can be accurately modified. With this lens system, we can obtain multi-iris, multi-focus, and multi-zoom images.2.Development of algorithms to extract high precision color information from multi-iris images and 3D range data from multi-focus images.3.Development of a multi-focus camera by modifying a commercial 3CCD video camera, Using this camera, three images taken with different focus values can be obtained at video rate.4.Development of an algorithm to measure 3D depth data from three defocused images taken by the multi-focus camera.5.Introduction of a coded apperture into the multi-focus camera, which allows us to measure 3D depth of textured surfaces and to recover an image completely focused over its visual field.6.Development of a fixed viewpoint pan-tilt camera system, whose projaction center is kept fixed against camera rotations.7.Development of versatile and fast algorithums to generate various types of ominidirectional panoramic images using the above camera.

通过系统地改变相机参数（例如，光圈、焦点、快门速度、观看方向等）所拍摄的多个图像的集成允许我们提取从单个图像不能或几乎不能获得的可靠场景信息。在这项研究中，我们开发的高精度多功能相机系统的基础上，这一想法。主要研究成果如下：1.研制了一种可精确调节光圈、焦距和变焦的计算机控制透镜系统。利用该透镜系统，我们可以获得多虹膜、多焦点和多变焦图像。2.开发了从多虹膜图像中提取高精度颜色信息和从多焦点图像中提取3D距离数据的算法。3.通过修改商业3CCD摄像机，开发了多焦点摄像机，使用该摄像机，可以以视频速率获得用不同聚焦值拍摄的三个图像。4.开发一种算法来从由多个摄像机拍摄的三个散焦图像测量3D深度数据。聚焦照相机5.将编码孔径引入到多聚焦照相机中，这允许我们测量纹理表面的3D深度并恢复完全聚焦在其视场上的图像6.开发固定视点的摇摄-倾斜照相机系统，其投影中心相对于摄像机旋转保持固定。7.开发通用和快速算法以使用上述摄像机生成各种类型的全向全景图像。
