Abstract:
1. A method of correcting an imaging position, comprising the steps of: moving a subject and a camera relatively; capturing an image of the subject with the camera in response to an imaging trigger; predicting a shift amount of a position where the imaging trigger is generated compared to a position where the image of the subject is captured, based on a relative moving speed of the subject and the camera in the capturing step; correcting a timing of generating the imaging trigger such that the imaging trigger is generated in a position that is shifted from the imaging position of the subject by a correction amount based on the shift amount obtained in the predicting step; and measuring a shift amount of a position where the imaging trigger is generated compared to a position of capturing the image of the subject, wherein the step of measuring the shift amount comprises a step of determining a shift amount prediction formula according to the relative moving speed and a moving distance of the subject and the camera, the shift amount prediction formula is defined by: ti D=b 0 +b 1 ·V+b 2 ·L wherein:
