White Balance - Sony EVI-D70 Technical Manual

To avoid AF error from continuous 24 hour AF
mode usage, daily initialization of lens system
using the CAM_Initialize command is
recommended.
The CAM_Initialize command takes less than 3
seconds to initialize the focus and zoom.
• Manual Focus Mode
MF (Manual Focus) has both a Standard Speed Mode
and a Variable Speed Mode. Standard Speed Mode
focuses at a fixed rate of speed. Variable Speed Mode
has eight speed levels that can be set using a VISCA
Command.
Will not stop by this command itself in Standard
Speed Mode and Variable Speed Mode. To stop, a
Stop command must be sent.
• One Push Trigger Mode
When a Trigger Command is received, the lens
moves to adjust the focus for the subject. The focus
lens then holds the same 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 C000 (10 mm).
The focus range is narrowed by excluding the
unnecessary range.

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.
