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 default 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 condition, 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 Automatic Exposure Mode The variety of AE functions, which allow video signal to output the optimum image for subjects from low light conditions to bright light conditions, are available. • Full Auto Auto Iris and Gain, Fixed Shutter Speed (NTSC: 1/60 s, PAL: 1/50 s) • Shutter Priority 1) Variable Shutter Speed, Auto Iris and Gain (1/1 to /1 10,000 s, 22 steps, std. shutter: 16 steps, slow shutter: 6 steps) • Iris Priority Variable Iris (F1.8 to Close, 18 steps), Auto Gain and Shutter speed • Manual Variable Shutter, Iris and Gain 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 1/30, 1/15, 1/8, or 1/4 s. 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 10,000 s. The iris and gain are set automatically, according to the brightness of the subject.
