Movement of a curling stone was studied with high precision by use of digital image analysis in order to obtain the relationship between curl ratio and both translational and angular velocities, using sequential images taken with a camera located on the ceiling. Calibrations to remove lens aberration were done prior to the experiment. Defining the line segment for movement of the curling stone in the time range of 0.5 sec, transition of curl ratio was measured in relation to a change of translational velocities in the movement of the curling stone. It was shown that the curl ratio is not uniform and has fluctuations in the change of the translational velocities.
