Functions - Sony DFW-V500 Manual

FUNCTIONS

The DFW-V500/VL500 differs from conventional analog cameras in that no video signals will be output by just supplying power.
It will start operating when designated commands are written in the CSR (Control & Status Register) specified in the 1394-based
Digital Camera Specification Ver.1.20. For details on the steps to video signal output and details of CSR, refer to "SETTINGS OF
CAMERA CONTROL AND STATUS REGISTER" on page 13 and "COMMAND SENDING PROCEDURE UNTIL IMAGES
ARE DISPLAYED" on page 22.
This chapter describes the functions of the camera which can be set using the CSR.
Camera Functions
Gain
Used for setting the gain of the video signal amplifier. The gain can be set in 18 steps between the standard gain and maximum
+18 dB.
By setting AUTO to ON, the gain will be automatically adjusted to the appropriate exposure. The range of operation is 0 to
+18 dB.
Note) For 18 dB, there may be an inconsistency of approximate +3 dB.
1 step is about 1 dB.
Shutter
The CCD exposure time can be set between the maximum 5 seconds and minimum 1/100,000 seconds. By setting the CCD
Iris to ON, the exposure time will be automatically adjusted to the appropriate exposure. The range of operation is 1/30 to
1/2,000 seconds.
Iris (DFW-VL500 only)
Used for setting the built-in zoom lens iris from fully opened (F1.8 at Wide end) to fully closed. By setting AUTO to ON, the
iris will be automatically adjusted to the appropriate exposure. The range of operation is about F1.8 to F32.
Auto Exposure
Used for setting the exposure compensation when Gain, Shutter, or Iris is operating in the AUTO mode. When Gain, Shutter,
and Iris are all set to Manual, the Auto Exposure setting will not be used. The range of operation is about –1EV to +0.5EV.
