Marking control device, laser application device, marking control method, and computer-readable recording medium having marking control program

A marking control device for controlling a marking device that marks a target image on a thermoreversible recording medium by applying a laser beam thereto, the marking control device comprising:

• a marking position determination unit configured to divide the target image into a first marking line and a second marking line that are adjacent to each other, and determine a marking position of each of the adjacent first and second marking lines;
• a marking line order determination unit configured to determine a marking order of the adjacent first and second marking lines for marking the target image such that the second marking line is marked by substantially reversing a scanning direction of the second marking line relative to a scanning direction of the first marking line;
• an adjusting unit configured to adjust, when the first marking line is initially scanned and the second marking line is scanned adjacent and subsequent to the first marking line by substantially reversing the scanning direction for marking the second marking line to start from a location near a first ending point of the first marking line so that the first marking line and the second marking line are close enough together so as to fill the target image, laser irradiation energy received by the thermoreversible recording medium so that the laser irradiation energy received by a second starting point of the second marking line is lower than the laser irradiation energy received by a second ending point of the second marking line;
• and
• a marking instruction generator unit configured to generate a set of marking instructions including the respective marking positions of the first and second marking lines and the marking order of the first and second marking lines.
