Functions SCB-1

5. FUNCTIONS

The SCB-1 can be controlled through a key-matrix or via RS-232 (SCOTI).

With the WolfVision SCB-1 Interface board the basic control functions can be done for

evaluation-purposes.

5.1 ZOOM

The SCB-1 uses an 12x zoom lens as well as a 2x digital zoom.

Optical 12x, f=5.8 to 69.6 mm (F=2.8 to 3.0)

The digital zoom is automatically switched ON at the tele end of 12x optical zoom range,

with progressive effect from 1 to 2, giving a total maximum 24x zoom ratio. Digital zoom

increases the picture element size and reduces the resolution.

Extended control of zoom:

• Direct zoom position

• Get current zoom position

• Zoom speed selection (15 speeds)

• Digital zoom can switched ON/OFF

• OSD-message or stop of zooming when digital-zoom is entered (selectable)

5.2 FOCUS

The minimum focus distance (MOD) is below 50mm at optical wide end and below 500mm

at optical tele end, and is independent of digital zoom. If shorter distance are necessary, a high

quality close up lens is available (see optional accessories). An Auto-Focus (AF) function is

also available (enabled by default).

Extended control of focus:

• Direct focus position

• Get current focus position

• Manual Focus speed selection (15 speeds)

• Focus can switched to Auto-Focus (permanent), One Push Auto- or Manual Focus

• Auto-Focus region can be switched between center (AF measures in the center area of

the image) and large (measure the complete image)

• Focus Priority: "Auto" - activates Auto-Focus by pressing a ZOOM-key
