To provide an imaging device, an imaging system, and a program capable of acquiring a photographed image without distortion while making a wide range possible to be photographed by providing a transparent cover.
An optical image regarding an originally adjacent object shifts a little and is formed on the image formation surface of a CCD resulting from a part where optical power becomes uneven. At this time, the photographed image becomes an image in which a shift area SA corresponding to light from the object which passes through the part where the optical power is uneven shifts by shift amount L to a non-shift area GS corresponding to light from an object which passes through a part where the optical power is even. Then, the distortion of the photographed image is corrected by inversely shifting the shift area SA to the non-shift area GS by the shift amount L on the basis of pan and tilt angles, shift data where positions of boundary lines SL1, SL2 are associated with the shift amount L, and the present pan and tilt angles to be detected.
