Basic Functions • Manual Focus Mode Manual Focus has both a Standard Mode and a Variable Mode. Standard Mode focuses at a fixed rate of speed. Variable Mode has eight speed levels that can be set using a VISCA Command. In these standard and variable modes, it is necessary to send Stop Command to stop the zoom operation. • One Push Trigger Mode When a Trigger Command is sent, the lens moves to adjust the focus for the subject. The focus lens then holds that 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 1000 (∞) to F000 (1 cm). Default setting: D000h (30 cm) White Balance White Balance has the following modes. • 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 2500K to 7500K. This mode is the factory setting. • ATW Auto Tracing White balance (2000K to 10000K) • Indoor 3200K Base Mode • Outdoor 5800K Base Mode • One Push WB One Push White Balance is a function that forcibly captures the white color once the lighting conditions to illuminate the subject are set, enabling you to shoot the image in the conditions as they are set. By using this function, the natural color of the subject can be obtained without being affected by the surrounding lighting conditions. To set this mode, shoot the subject that you want to capture the white color and send the One Push White Balance Trigger. • Manual WB Manual control of R and B gain, 256 steps each Automatic Exposure Mode A variety of AE functions are available for optimal output of subjects in lighting conditions that range from low to high. • Full Auto Iris, Gain and Shutter Speed can be set automatically. • Gain Limit Setting The gain limit can be set at the Full Auto, Shutter Priority, Iris Priority, Bright and Manual in the AE mode. Use this setting when image signal-to-noise ratio is particularly important. • Shutter Priority 1) Variable Shutter Speed, Auto Iris and Gain (1/1 to 1/10,000 sec., 16 high-speed shutter speeds plus 6 low-speed shutter speeds) 1) Flicker can be eliminated by setting shutter to 1/100s for NTSC models used in countries with a 50 Hz power supply frequency 1/120s for PAL models used in countries with a 60 Hz power supply frequency • Iris Priority Variable Iris (F1.6 to Close, 14 steps), Auto Gain and Shutter speed • Manual Variable Shutter, Iris and Gain • Bright Variable Iris and Gain (Close to F1.6, 14 steps and F1.6 at 15 steps) 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 adjusted the slow shutter according to subject brightness. The picture output is read at a low rate from the memory. 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.
