1. An imaging device comprising:
a camera that outputs several pieces of photographed data obtained at a constant period by photographing an image on the basis of a camera output signal generated with the constant period, the image being printed on a printing medium transported in a first direction;
an image data output unit that outputs image data based on said photographed data to an external device; and
an external output signal generator that generates an external output signal indicating timing of output of said image data by said image data output unit,
wherein said image data output unit includes:
a buffer configured to store the several pieces of the photographed data output at the constant period from said camera;
a rate setting unit configured to set a weight responsive to a time gap between said camera output signal and said external output signal; and
an averaging processor that calculates a weighted average of said several pieces of photographed data stored in said buffer at the constant period using respective weights set by said rate setting unit, and
wherein said image data output unit outputs an image represented by said weighted average calculated by said averaging processor as said image data.
