Configuration of the camera
All camera settings are made by writing specific values into the corresponding
registers.
This applies to:
•
values for general operating states such as video formats and modes,
exposure times, etc.
•
extended features of the camera that are turned on and off and
controlled via corresponding registers (so-called advanced registers).
Camera_Status_Register
The interoperability of cameras from different manufacturers is ensured by
IIDC, formerly DCAM (Digital Camera Specification), published by the IEEE1394
Trade Association.
IIDC is primarily concerned with setting memory addresses (e.g. CSR:
Camera_Status_Register) and their meaning.
In principle all addresses in IEEE1394 networks are 64 bits long.
The first 10-bits describe the Bus_Id, the next 6 bits the Node_Id.
Of the subsequent 48 bit, the first 16 bit are always FFFFh, leaving the
description for the Camera_Status_Register in the last 32 bit.
If a CSR F0F00600h is mentioned below this means in full:
Bus_Id, Node_Id, FFFF F0F00600h
Writing and reading to and from the register can be done with programs such
as FireView or by other programs developed using an API library
(e.g. FirePackage).10Every register is 32 bit (big endian) and implemented as
follows (MSB = Most Significant Bit; LSB = Least Significant Bit):
