9-4. Connection Picture of the Measuring
Instrument(On Automatic control)
(1) Inside PATTERN is used when W/B is controlled. Connect
to auto controller or push control R/C IN-START -> Enter
the mode of White-Balance, the pattern will come out.
Full White Pattern
RS-232C Communication
(Fig.6) Auto AV(CVBS) Color Balance Test Pattern
9-5. Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked.(illumination is less than 10ux)
(2) Measure and adjust after sticking the Color Analyzer(CA-
100+, CA210) to the side of the module.
(3) Aging time
- After aging start, keep the power on(no suspension of
power supply) and heat-run over 15minutes.
- keep white pattern using inside pattern.

13-3. Method & Notice
(1) Serial number D/L is using of scan equipment.
(2) Setting of scan equipment operated by Manufacturing
Technology Group.
(3) Serial number D/L must be conformed when it is produced
in production line, because serial number D/L is mandatory
by D-book 4.0.
