In this explanation, when a plurality of spotlights are designated during a light-matching operation for adjusting the direction of the spotlights, when the irradiation points are designated, all the designated spotlights irradiate one irradiation point. The operating mode of the spotlight If you specify to, the PA of the spotlight is specified by designating the irradiation point of one master spotlight.
The N, TILT data is supplied to other designated slave spotlights, and the slave spotlights can obtain stereoscopic parallel beams with the master spotlight.

This operation creates a uniform line-shaped irradiation surface on the studio floor or the horizontal surface, or creates smoke by creating a curtain of light, and has the effect of swinging this curtain of light back and forth, left and right. It can be a very effective means.

Further, in this device, the display screen of the image display device 2 displays the set drawing, the spotlight used, the irradiation direction, and the like, which is exactly the same as the lighting preparation drawing used by the conventional lighting planner. The fact that it can be used as a recording of the lighting plan by making a hard copy on the printer 18 is very useful and effective as a reference material for studying the effect of the stage lighting and the subsequent plans.

[Advantages of the Invention] With the spotlight control device according to the present invention having the configuration described in claim 1, the plan view and the attachment position of the spotlight are two-dimensionally displayed on the image display device, and irradiation is performed on the display. By specifying and inputting points, the horizontal angle, vertical angle and other control items of the spotlight can be controlled. Therefore, when a lighting plan drawn by a lighting planner in a conventional studio or hall is drawn on the image processing apparatus, a plurality of spotlights immediately operate, and it is possible to perform lighting adjustment while checking the lighting effect.

Therefore, conventionally, based on the plan drawing drawn by the lighting planner, the work of adjusting the direction, focus, or bander of many spotlights (mostly work at height)
Such complicated operations can be omitted, and very precise production lighting can be realized.

Further, by constructing according to claim 2, the plan drawing and the layout drawing of the spotlights displayed on the image display device can be partially enlarged and displayed, which facilitates fine adjustment of the irradiation point and accurately. It can be carried out.

Furthermore, since the plan diagram according to the change of the scene can be selectively displayed by configuring as in claim 3, the spotlight can be moved systematically or ad-lib according to the progress of the studio or the progress of the production. Can be done.

As described above, it is possible to provide a spotlight control device having many advantages.
