PURPOSE: To provide an image device for tube inside inspection with which tubes can be observed over all the inner peripheries and further, the distortion of a provided image is reduced. CONSTITUTION: This device is provided with a two-dimensional image sensor 13 to be inserted to the inside 11 of tubes, mirror 14 arranged obliquely in this image pickup direction, turning means 5 for the mirror 14, rotary encoder 16 for detecting the turning angle of that turning means, image memory for storing the image output o the two-dimensional image sensor 13, and controller for these parts. This controller is provided with a rotary distortion correcting means for correcting the rotary distortion of the image stored in the image memory, bending distortion correcting means for correcting the bending distortion of the image caused by image pickup, and image linkage processing means for linking forward and backward divided corrected images by detecting the overlapped part of forward and backward divided corrected images divided every specified angle, picked-up and corrected by the two-dimensional image sensor 13. |
