− 28 −Optical Zoom Limit SettingsThe optical zoom magnification can be limited usingthe Optical Zoom Tele Limiter command. The digitalzoom cannot be used if the limit is set to the Tele side.Digital ZoomA maximum of 16x digital zoom can be set with theDigital Zoom Tele Limiter command. Together withthe optical zoom, a maximum of 480x is possible,however, the resolution decreases.Although the vertical resolution can be increased byenabling the V-Reso.UP function using the V-Reso.UP ON command, residual images and blurring maybecome more apparent with moving subjects.[2] Focus ControlManual FocusThe manual focus can be operated using Far/Near ordirectly moving the focus to a specific position.Far /Near⁃Transmit the Far or Near command to execute theFar/Near operation at the speed configured by theFar/Near Speed command. The Stop commandstops the operation. (The operation does not stopwithout transmitting the Stop command.)The speed targets are as follows.SettingsRequired Time (s) from Near End → Far Endat the Near Limit 1m and Tele Endx36 MD700MD800 x30 MD500MD600 x22 MD300MD4001 19.7 16.0 19.02 10.3 8.3 9.73 4.4 3.6 6.64 2.4 2.1 5.2Direct⁃The Direct command can move the zoom lens to thespecified focus lens position.Auto Focus⁃The Auto Focus ON command sets the mode to autofocus and automatically focuses on the subject ifthe subject moves. This mode is cancelled when theManual Focus ON, Near, or Far command is used.Although the minimum focus distance is set to 1m bydefault, this can be changed by using the Near Limitercommand. In addition, the sensitivity of the AF to thechange in subject can be changed using the AutoFocus Sensitivity command and the focusing area canbe changed using the Focus Area command.One-Push Auto FocusThe auto focus can be moved only once using theOne Push Trigger command. The mode prior tostarting the auto focus is retained after focusing.Focus Lens OffsetWhen covering a camera, such as the dome camerawith a cover or similar, the refraction of the light due tothe cover changes the OPL. This may result in closesubjects being out of focus when using a powerfulzoom.In that case, it is necessary to move the range ofmotion of the focus lens depending on the change inOPL.Validate the Offset using the Cover Offset ONcommand and transmit a Cover Offset Levelcommand so that subjects that are at approximately1m TELE edge (When the Near Limit is 1m) are infocus.In the same way that 0 sets the level to OFF, thelarger the number, the greater the offset.[3] White Balance ControlATW⁃Auto Trace White Balance.・SMART ATWThis mode controls retracing of ATW accordingto the size of single-colour object in the screen,addition to normal ATW mode control.In case the single-colour object covers most ofthe area in the screen, WB control function shallbe stopped.Also, the retracing speed is slower than that ofnormal ATW mode.*This mode is valid when WB mode is set to ATW.AWC⁃The Push-Lock Auto White Balance starts retractingusing the One Push Trigger command and locks thewhite balance after approximately 2 seconds.In addition, after executing the One Push Triggercommand, the mode returns to the previous modeby executing the AWC Reset command.3200K⁃Color temperature 3200K fixed mode.5600K⁃Color temperature 5600K fixed mode.FLUO⁃Color temperature 4200K fixed mode.MWB⁃Manual White Balance. The R and B gains can eachbe configured to a range of 0 to 255.Function Descriptions
