3.2 Exposure Control

3.2.1 Setting the Exposure Time

Exposure time is determined by the value stored in the Shutter control register (see page 4-9).

The value in the register can range from 1 to 4095 (0x001 to 0xFFF). The value in the register

represents

n in the equation: Exposure Time = n x 20 µs. So, for example, if the value stored in

the Shutter register is 100 (0x064), the exposure time will be 100 x 20 µs or 2000 µs.

If you are operating the camera at a standard frame rate, you can determine the maximum shutter

setting for that frame rate by reading the Max_Value field of the Shutter_Inq register (see page 4-

6).

3.2.2 Maximum Exposure Time

The maximum exposure time for a given frame rate is determined by the following formula:

For example, if a camera is operating at 40 fps:

So in this case, the maximum exposure time is 25.0 ms.

Exceeding the maximum exposure time for your frame rate will cause the camera to

slow down, i.e., it will cause the camera to operate at a lower frame rate.
