1-1-4. Using Method of SEUS

The application for adjustment (SEUS) is used to change the coefficient for calculating the signal processing or EVR data. The SEUS performs two-way communication between PC and set through the USB terminal. The two-way communication result data can be written to the nonvolatile memory.

1. Connection

1) Connect the HASP key to the USB terminal of the PC.

2) Connect the PC and set with the USB cable.

3) Confirm that the set starts in the USB mode.

4) Start the SEUS on the PC.

5) Click [Connect] on the SEUS screen. If the connection is normal, the SEUS screen will be as shown in Fig. 6-1-8, indicating the

“connected” state.

Note: The SEUS will go in

turned off (for instance, by resetting the set). In such a case, click [Connect] on the SEUS screen to restore the

1-2. ADJUSTMENT PROGRAMS

The DSC-T3 is adjusted with the Automatic Adjustment Program and the Color Adjustment Program. The Automatic Adjustment Program automatically controls the adjustment operations that were formerly entered manually on the operation screen of the SEUS (some adjustments may be manually operated on the SEUS operation screen). The Color Adjustment Program automatically performs “AWB 3200K-5800K Standard Data Input”, “Color Reproduction Adjustment” and “Color Reproduction Check” of Camera System Adjustment.

1-2-1. Automatic Adjustment Program

1. Precautions When Using Automatic Adjustment Program

1) The Automatic Adjustment Program writes the adjustment re-

sults such as EVR data to the set through two-way communication with the camera via the SEUS. Accordingly, the Automatic Adjustment Program must be used in the environment where the SEUS operates.

2) The program run time may vary depending on the environ-

ment of the personal computer used.

3) Even if the Automatic Adjustment Program is used without

starting the SEUS, the SEUS will start automatically when the adjustment is executed. Howe ver, it may tak e time for the SEUS to start, and therefore the Automatic Adjustment Program should be used with the SEUS started in order to reduce the program run time.

2. Start of Automatic Adjustment Program

Double-click the application file (DSC-T3 Auto-Adj Ver_1.[]r
