Automatic Lens Calibration

OptiCal (Primary Lens Calibration): OptiCal provides the ability to store and recall focus, zoom and position settings for the primary lens.

To enable OptiCal:

1.Select Installation from the Main Menu.

2.Select Geometry and Color from the Installation menu.

3.Select OptiCal from the Geometry and Color menu.

4.Press ENTER to check the box labeled OptiCal.

1. OptiCal control is a preference setting and is retained between power

Note cycles.

2.OptiCal has no effect on the secondary anamorphic lens, only the primary lens.

5.Press EXIT to exit the Geometry and Color menu.

6.Select Calibration and Test Patterns from the Installation Menu.

7.Select OptiCal from the Calibration and Test Patterns Menu.

OptiCal gives you a choice of three types of lens calibrations:

•A Reference calibration establishes a reference point (starting position) for measuring relative lens movement. All distances are measured from this reference point. A reference calibration is lost when power is removed from the projector and occurs on every power-up as long as OptiCal is enabled.

•A Motion calibration determines the characteristics of each motor and values are saved in the projector’s memory. If OptiCal is enabled and a motion calibration has previously been done, the projector automatically recalls these settings from memory when it’s being powered up and a motion calibration will not take place.

•A Full calibration performs both a Reference calibration and a Motion calibration.

If no calibration has previously been done you may be prompted to do a Full calibration. If a motion calibration has been done, you will be prompted to complete a reference calibration. If both calibrations have been done, the OptiCal checkbox is checked and OptiCal enabled.

When OptiCal is enabled, the Vision 140/150 performs a reference calibration when the projector is turned on. The lens returns to its last saved position (or actual position, if no motion calibration has been done previously). Further adjustments to the zoom, focus and position are automatically saved.

When both OptiCal and Automatic Lens Calibration are enabled, the Vision 140/150 performs a Full calibration when the projector is turned on. During calibration, the shutter closes and the status LED (see Figure 2-3)displays “LC.”

If OptiCal is disabled (refer to OptiCal (Primary Lens Calibration)

Note above), the Automatic Lens Calibration setting has no effect.
