Basic Functions Basic Functions Overview of Functions Zoom The EVI-D100/P uses an 10× optical zoom lens. And its digital zoom function allows you to zoom up to 40×. • Optical 10×, f = 3.1 to 31 mm (F 1.8 to F 2.9) The horizontal angle of view is approximately 65 degrees (wide end) to 6.6 degrees (tele end). Digital zoom increases the picture element size and reduces the resolution. Extended control of zoom: • Direct zoom position • Zoom speed selection (8 speeds) • Digital zoom can be switched ON/OFF Focus The minimum focus distance is 100 mm at the optical wide end and 600 mm at the optical tele end, and is independent of the digital zoom. The AutoFocus (AF) function automatically adjusts the focus position to maximise the high frequency content of the picture in a center measurement area, taking into consideration the high luminance and strong contrast components. Note AVOID 24-hour continuous use of the autofocus. This may cause lens malfunction. All of these settings are performed via RS-232C control. If the RS-232C is not used, white balance, iris and gain adjustments will be carried out automatically, and the shutter speed will be fixed at 1/60 seconds for the EVI-D100 and 1/50 seconds for the EVI-D100P. Extended control of focus: • Direct focus position • Minimum focus distance limitation • Manual focus speed selection (8 speeds) • AutoFocus can be set to High or Low mode • One Push AF can be achieved in manual focus mode • HIGH AF High reaction speed of the AF. Use this mode when shooting fast moving objects. Recommended as the optimum mode for normal NON-CONTINUOUS use. • LOW AF Better focus stability. In low luminance conditions, the AF discontinues operation even when brightness changes, enabling stable images. White Balance • Auto Auto Tracing White Balance with limitations on R and B gain (3000 to 7500 K), to avoid fixing single color scenes as 'white' • ATW Auto Tracing White balance (2000 to 10000 K) • Indoor 3200 K • Outdoor 5800 K • One Push WB One Push White Balance 1) • Manual WB Manual control of R and B gain, 256 steps each 7
