Many types of motion blur car be can be distinguished all of which are due to relative motion between the recording device and the scene.
This can be in the form of a translation, a rotation, a sudden change of scale, or some combinations of these. here only the important case of a global translation will be considered.
when the scene to by recorded translates relative tothe camera at a constant velocity (V relative) under an angle of 0 radians with the horizontal axis during the exposure interval [0, T exposure], the distortion is one-dimensional.
