Basic Functions Focus Focus has the following modes, all of which can be set using VISCA Commands. • Auto Focus Mode The Auto Focus (AF) function automatically adjusts the focus position to the high frequency content of the picture in a center measurement area, taking into consideration the high luminance and strong contrast components. The minimum focus distance is 10 mm at the optical wide end (extreme close-up settings with VISCA control) (distance from the front end of the lens). - Normal AF Mode This is the normal mode for AF operations. - Interval AF Mode The mode used for AF movements carried out at particular intervals. The time intervals for AF movements and for the timing of the stops can be set in one-second increments using the Set Time Command. The initial value for both is set to five seconds. - Zoom Trigger Mode When the zoom is changed with the TELE or the WIDE buttons, the pre-set value (initially set at 5 seconds) becomes that for AF Mode. Then, it stops. • Manual Focus Mode MF (Manual Focus) has both a Standard Speed Mode and a Variable Speed Mode. Standard Speed Mode focuses at a fixed rate of speed. Variable Speed Mode has eight speed levels that can be set using a VISCA Command. To stop the required operation after sending a Standard Speed command or a Variable Speed command, send the Stop command. • One Push Trigger Mode When a Trigger Command is received, the lens moves to adjust the focus for the subject. The focus lens then holds the same position until the next Trigger Command is input. • Infinity Mode The lens is forcibly moved to a position suitable for an unlimited distance. • Near Limit Mode Can be set in a range from about 4.5 m (2000) to 1 cm (C000). The focus range is narrowed by excluding the unnecessary range. White Balance White Balance has the following modes, all of which can be set using VISCA Commands. • Auto White Balance This mode computes the white balance value output using color information from the entire screen. It outputs the proper value using the color temperature radiating from a black subject based on a range of values from 3000 to 7500K. This mode is the default setting. • Indoor 3200 K Base Mode • Outdoor 5800 K Base Mode • One Push WB The One Push White Balance mode is a fixed white balance mode that may be automatically readjusted only at the request of the user (One Push Trigger), assuming that a white subject, in correct lighting conditions and occupying more than 1/2 of the image, is submitted to the camera. One Push White Balance data is lost when the power is turned off. If the power is turned off, reset the One Push White Balance. • Manual WB Manual control of R and B gain, 256 steps each 7
