1. An imaging apparatus, comprising: a shooting optical system; an image sensor; an image data producer which produces image data from an image of a photographic subject formed on the image sensor via the shooting optical system; an imaging controller which repeatedly outputs one picture unit of image data produced in a predetermined shooting time duration by the image data producer; an image data recorder which records the image data outputted by the imaging controller; a position detector which detects a change in position of the imaging apparatus and calculates an amount of displacement of the imaging apparatus from a position at a time point of the imaging apparatus taken as a reference based on the detected change in position; a position recorder which records the amount of displacement calculated by the position detector and time data related to the amount of displacement; a display section which displays a relationship between a shooting time of each image data of the image data recorder and the amount of displacement recorded by the position recorder, during exposure or at the end of exposure; and an adding processor which adds arbitrary image data of the image data recorder and produces an image.
