<P>PROBLEM TO BE SOLVED: To provide an omnidirectional camera which does not need complex curved surface distortion correction and allows a mirror to be easily manufactured by eliminating the uselessness of pixel cells which is the problem of the conventional curved surface mirror. Ž<P>SOLUTION: The omnidirectional camera comprises a downward reflecting mirror 1 and an upward camera 2, the downward reflecting mirror 1 and the upward camera 2 are housed in a cylindrical transparent case 3, the cylindrical transparent case 3 is rotated by a pulse motor 4, the camera 2 photographs an image of a circumference of 360 degrees reflected on the side surface of the reflecting mirror 1, and the image is developed into an omnidirectional image. The reflecting mirror 1 is a regular quadrangular pyramid with a square bottom, wherein a triangular plane mirror is arranged on four planes of the side surface. The camera 2 forms the image reflected on the reflecting mirror 1 through a lens 5 on an image sensor 6. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
