Basic Functions 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 factory setting. • ATW Auto Tracing White balance (2000 to 10000 K) • 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 One Push White Balance. • Manual WB Manual control of R and B gain, 256 steps each Automatic Exposure Mode The variety of AE functions, which allow video signal to output the optimum image for subjects from low light condition, to high light conditions, it is available. • Full Auto Auto Iris and Gain, Fixed Shutter Speed (NTSC: 1/60 sec., PAL: 1/50 sec.) • Shutter Priority 1) Variable Shutter Speed, Auto Iris and Gain (1/1 to 1/10,000 sec., 22 steps, std. shutter: 16 steps, slow shutter: 6 steps) 1)Flicker can be eliminated by setting shutter to t1/100s for NTSC models used in countries with a 50 Hz power supply frequency t1/120s for PAL models used in countries with a 60 Hz power supply frequency • Iris Priority Variable Iris (F1.6 to Close, 18 steps), Auto Gain and Shutter speed • Manual Variable Shutter, Iris and Gain • Bright Variable Iris and Gain (Close to F1.6, 17 steps at 0 dB: F1.6, 15 steps from 0 to 28 dB) AE - Shutter priority The shutter speed can be set freely by the user to a total of 22 steps - 16 high speeds and 6 low speeds. When the slow shutter is set, the speed can be 1/30s, 1/15s, 1/8s, 1/4s, 1/2s, 1/1s. The picture output is read at a normal rate from the memory. The memory is updated at a low rate from the CCD. AF capability is low. In high speed mode, the shutter speed can be set up to 1/10,000s. The iris and gain are set automatically, according to the brightness of the subject.
