PROBLEM TO BE SOLVED: To provide a self-propelled type pipe inside inspection camera device capable of replacing direct view/side view operations, reduced in size and simplified in constitution by fixing an illumination mechanism and constituted so as to perform proper illumination free from irregularity with respect to the full view direction of a camera. SOLUTION: A main control part 100 is constituted so as to individually perform the lighting drive control of a direct view light condensing illumination part 15 [light condensing illumination (1)], a direct and oblique view diffusion illumination part 16 [diffusion illumination (2)] and a side view diffusion illumination part 17 [diffusion illumination (3)] on the basis of the sight direction angle detection signal of an imaging part 13 outputted from a potentiometer 113 through constant current control circuits 121, 122 and 123.
