Title

: Projector Reference Information (QUICS/SERVICE/STANDARD GUIDELINES)

Setup file : ccdcinst.exe

Projected images taken with a digital camera are downloaded to a computer with this software installed.
The software analyzes the images’ color irregularities and saves and transfers the resulting correct settings.
The software package includes the instructions for taking projected images, operating the projector
(command communications), correcting the color irregularities, and transferring the resulting data.    This is
a comprehensive, user-friendly color irregularity correction tool.

This program is created based on the color irregularity correction software that is used in Sharp’s production
line.  The teaching data* for this correction is the same as the one that is employed in the production line.

With the software installed, the Z7000 and C20 data are readily available.
For future projector models, their updated data will be supplied in due date and can be added by import
function to this system.
* Teaching data: LCD characteristics data needed for correction-determining calculations

Press the    Take picture    button for capturing images.

STEP 2: Download the pictures to the computer, and correct and transfer the new settings.
