<p><P>PROBLEM TO BE SOLVED: To provide a position adjustment system by which accuracy in the position adjustment of a light emitting tube and a reflector can be improved, and to provide a position adjustment method, a recording medium, and a program. <P>SOLUTION: The position adjustment of a sub-mirror 13 and a light emitting tube 11 and the position adjustment of the elliptic reflector 12 and the tube 11 are carried out with a position adjustment device 6. Power and luminance needed for the amount of position adjustment are measured to calculate the value of luminous flux/power. The amount of position adjustment and the characteristic of the average of the luminous flux/power are obtained. On the basis of that, an optimum position is calculated by an optimum-position detecting part 645. Further, an amount of displacement between the present position of the sub-mirror 13 and its optimum position obtained from an approximation curve is calculated. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
