Menu item SPEED SENSITIVITY LEVEL ALC MAX PRIORITY Function/variable range MEMO • When the shutter speed is slower than 1/4 s (1/15 s in the VGA DRAFT mode), the screen update rate becomes longer in correspondence with the shutter speed, and time will be required for the following operations. Auto white, auto iris, ALC If the shutter speed is set at 1.4 s or slower, these operations behave as follows. Auto white : Auto white balance function cannot be started. ( ੬ page 30 White balance adjustment) Auto iris : Stops at the iris value at that time. ALC : Stops at the sensitivity at that time. To use a shutter speed of 1.4 s or slower, use with the following settings selected: IRIS MODE : MANUAL SENSITIVITY : STEP or V.SENS • There may be shortage of light when increasing the shutter speed. In this case, adjust the iris or sensitivity. Spe- cial attention is required for the picture quality when rais- ing the sensitivity since images may show artefacts. Default value Used to set the sensitivity mode. STEP: the sensitivity can be changed by means of the LEVEL submenu item. ALS: the sensitivity si automatically changed by the ambient brightness. Maximum sensitivity is set in the next ALC MAX menu item. V.SENS: the sensitivity can be set in detail using the LEVEL submenu item. STEP The sensitivity can be changed when the sensitivity mode is set to STEP or V.SENS. [STEP variable range: ISO100, ISO200, ISO400] [V.SENS variable range: ISO100 ~ ISO400] STEP: ISO100 V.SENS: ISO100 This can be set when the sensitivity mode is set to ALC. Used to set the maximum sensitivity of ALC, which automatically switches the sensitivity depending on the brightness. [Variable range: ISO200, ISO400] ISO400 Used to set which device has output priority when both printer and MO or Zip® drive are connected. PRINTER: output priority is given to the printer. DISK: output priority is given to the MO or Zip® drive. DISK E63
