Installation and Calibration of Calibration Camera (LKRA-PCAB1)

The LKRA-PCAB1 (herein referred to as the "calibration camera") can be used to automatically calibrate
deviations that may occur in the convergence due to aging between the two projectors that comprise the
dual system. You can perform calibration using the LCD panel and touch sensor via simple operations
with each calibration operation taking about 5 minutes (when "STATIC" is selected for "CALIBRATION
MODE").
The alignment DCP is required for the calibration. For obtaining the alignment DCP, contact your local
Sony Sales Office/Service Center.

. Install the calibration camera in a stable location free from vibration.
. Make sure that there are no obstructions between the calibration camera and screen.
. Make sure the calibration camera's lens is clean.
. When installing the calibration camera in a projection room, adhere to the following.
- Keep the projection room as dark as possible.
- Install the calibration camera close to the glass, and use blackout curtains, for example, to prevent
light from the projector or reflections from other light sources in the room from entering the calibra-
tion camera.
. Use the calibration camera with the screen having the screen gain of 2.4 or below.
. Install the calibration camera so that the T = (distance between the screen and calibration camera (m)) /
(screen width (m)) value is between 1.05 and 4.0.
. As a general reference, install the camera within 1 m of the screen's center axis.
