6.3.3 Activating a Shading Values File
As explained in Section 6.3 on page 121 , the camera contains a set of factory determined shading
correction values in a file in its non-volatile memory. As explained in Section 6.3.2 on page 123 , you
can also generate a set of "user" shading values and save them to a separate file in the non-volatile
memory.
Assuming that you have generated user shading values, you can choose to “activate” either the
user shading values file or the factory shading values file. When you activate a shading values file,
two things happen:
„
The values from the activated file are immediately copied into the camera’s volatile memory.
When you have shading correction enabled, the camera uses the shading values in the volatile
memory to perform shading correction.
„
A link is created between the activated file and the volatile memory. The shading values from
the activated file will automatically be copied into the volatile memory whenever the camera is
powered up or reset. (Assume, for example, that the user shading values file is the activated
file. In this case, when the camera is powered on or reset, the values from the user shading
values file will be copied into the volatile memory of the camera and will be used to perform
shading correction.)
Activating a Shading Values File
You can activate a shading values file with the Camera Configuration Tool Plus (CCT+) or by using
binary read/write commands from within your own application to set the camera’s bulk data control
and status registers (CSRs).
With the CCT+
With the CCT+ (see Section 7.1 on page 156 ), you use the File Name Select parameter to select a
shading values file and the Activate button in the Shading Files parameters group to activate the
selected file.
By Setting CSRs
You can activate a shading values file by writing values to the shading values bulk data CSR.
Section 7.2.3 on page 188 explains bulk data CSRs and using the bulk data activate process.
Section 7.3.1 on page 197 explains using read/write commands.
