Setting the Absolute Exposure Time

If you adjust the exposure time by writing a value to the Absolute Exposure Time field of the
Exposure Time CSR, you can write a floating point value from 4.56 to 19119997.00 (decimal) in
increments of 0.01. Writing a floating point value to the absolute register sets the exposure time
directly in microseconds For example, if the absolute exposure time was set to 13.68, then the
camera would be set for 13.68 µs of exposure.

Guidelines

When you are working with a parameter that can be entered as either raw or absolute, there are
two important things to keep in mind:

• You do not need to enter values in both the raw field and the absolute field. Entering just one

value is sufficient and you can choose between fields whichever one suits your needs best.

• However, in the absolute fields, only equivalents of values entered in the raw field are

allowed.

For illustration, let’s consider the preceding example using the first formula from the previous
page. Calculating the microseconds of exposure that the camera would produce for three dif-
ferent settings in the raw exposure time field of the exposure time CSR, we obtain:

This means that if you entered a value in the absolute field, values of e.g. 4.56, 9.12, or 13.68
would be “valid” because they are the equivalents to 1, 2, and 3, respectively, in the raw field.

However, for example, a value of 13.69 entered in the absolute field would not be valid
because it is not the equivalent of any value you could enter in the raw field.

What happens if you enter an “invalid” value in the absolute field? This is not really a problem
because the camera will automatically change the value you entered to the nearest valid
value. For example, if you entered 13.69 in the raw field, the camera would automatically
change the value to 13.68.

Because the camera automatically changes any entry in an absolute field to the nearest
“valid” value, you do not need to worry about entering equivalent values. However, you do
need to be aware of the camera making small adjustments (unless you entered a „valid“
value).

Accordingly, if you read back a value in an absolute field, you may find that it is slightly differ-
ent from the value that you entered the field.
