ABSTRACT:
An improved flange-back adjustment method for a video camera capable of advantageously reducing the time needed for adjusting the flange-back and capable of correctly performing the flange-back adjustment is disclosed. The method includes determining a value of a first position on an actual trace curve, determining a value of a second position on the actual trace curve, calculating a difference between the first position value and the second position value, determining two corresponding points on a stored trace curve based on the calculated difference, and determining flange-back values based on these determinations.
