When the AUTO set switch is turned to AWC, the white balance will be automatically set. While the system being set, auto warning indicator (LED) blinks out when the white balance setting is completed. lamp remains lit, the setting must be tried RCU (RCB) AUTO LED AUTO set switch -23 Adjustment Notes: • For white balance setting aim the camera at a white object and try to position it in the center of the monitor screen. The object must appear in over 10 % of the total monitor screen area. Try to avoid overly bright objects in the scene. • White balance may not be correctly set if the lighting of the object is too weak. The white object must occupy over 10 % of the monitor screen area. • Since the camera has a built-in memory, the balance will remain in the memory even off. Therefore, it is not necessary to reset balance if the color temperature of unchanged. However, it must be temperature changes, such indoors to outside, or vice • When the camera is used gain adjustment of reset to ±0 after in only User Mode.) $ Automatic tracking white balance setting (ATW) White balance will be automatically set to continuously match changes of light source and color temperature while the white balance setting is set to ATW. Notes: • ATW might not function properly when high brightness light (ex. fluorescent lamp) beams into a screen. • White balance may not be accurately set if there is no white object in the scene being shot. $ Manual white balance setting [ADJUSTMENT by CAMERA] Manual setting is possible in User Mode only. 1. Select the white balance mode either AWC A or by menu. 2. Aim the camera at a large white object. Press ITEM/AWC switch for over 2 second. 3. Adjust the red gain/blue gain control in item of Color Set sub menu of User wave of the white portion of the minimum width or the white object appears pure white. (Use monitor for precise adjustment.) [ADJUSTMENT with After AWC setting, same way as described -24 Minimize the carrier wave using the red & blue gain controls Waveform for white balance set chart $ Reset to 3200K or 5600K white balance When the white balance setting is set to either “3200K” or “5600K” the white balance will be automatically set to the color temperature 3200K or 5600K, respectively. $ Black balance adjustment • Close the lens. If the motor drive lens is controlled from lens is automatically closed when the adjusted. • When the camera is used without pedestal adjustment of painting automatically reset to ±0 after (painting setting in only [ADJUSTMENT by Press the YES/ABC balance will be In user mode, black balance fine adjustment can be performed with the red pedestal/blue pedestal setting after setting the black balance. [ADJUSTMENT with the RCU (RCB, Hybrid control panel)] Set the AUTO set switch to ABC and the black balance will be automatically set. While the system is being set, the auto warning indicator (LED) blinks and it goes out when the black balance setting is completed. If the lamp remains lit, ABC should be tried again. YES/ABC switch AUTO LED AUTO set switch -25 Adjustment $ Total pedestal level adjustment (Use an oscilloscope or a waveform monitor for this adjustment. ) This step is to adjust the black levels (pedestal levels) of two or more cameras to be the same. [ADJUSTMENT by CAMERA] 1. Close the lens. 2. Select Pedestal item in the brightness setting Sub Menu. (Select [Pedestal] in the [Iris, Shutter, Gain Set] sub menu in User Mode.) 3. Set the pedestal level to 5 IRE (0.035 V) with the YES/ABC switch or the NO/BAR switch. [ADJUSTMENT with RCU (RCB, Adjust the pedestal level to 5 adjustment. NO/BAR switch YES/ABC switch TOTAL PEDESTAL -26 $ Gen-lock adjustment Phase adjustments must be performed with the camera or the RCU (RCB) when external synchronizing signals are supplied to the system in cases where multiple cameras are used or peripheral devices are connected. U Horizontal phase control Observe the waveform of the external synchronizing input signal (black burst signal) and video output signal on a two-channel oscilloscope. Then match the horizontal phase of both signals by adjusting them with the cameras or RCU’s horizontal phase control. External gen-lock input signal (black burst output of special effect generator) Video signal Adjust the horizontal phase [ADJUSTMENT by CAMERA] 1. Press the NO/BAR switch for the color bar. 2. Select [G/L Adjustment] Phase] on the submenu. 3. Adjust the horizontal NO/BAR switch. NO/BAR switch YES/ABC switch [ADJUSTMENT with RCU (RCB, Hybrid control panel Use the horizontal phase control. Horizontal phase Subcarrier phase fine control Subcarrier phase coarse control control -27 Adjustment Caution: • When horizontal phase adjustment is required using RCU (RCB) or hybrid control panel, BAR/CAM switch should be set to BAR. Horizontal phase cannot be adjusted if the switch is in the CAM position. After adjustment set BAR/CAM switch back to CAM. • When horizontal phase adjustment is moved, color phase is also moved.
