EXPOSURE CONTROL

2.4.1 Electronic

Shutter

During normal camera operation, the exposure time is fixed and determined
by the frame rate. The electronic shutter can be used to precisely control the
image exposure time under bright light conditions. The electronic shutter
does not affect the frame rate, it only reduces the amount of electrons
collected. The desired exposure time is set by positioning a short pulse,
SHUTTER, with respect to the vertical transfer pulse, VCCD – Figure 2.34.
The electronic shutter pulse can be positioned within the entire frame timing
period with a precision of 10 microseconds - refer to the ‘sst’ command.
The minimum shutter position is 50 microseconds.

Figure 2.34 - Electronic Shutter Position

CAUTION NOTE

1.

The electronic shutter can be enabled in all camera modes.

2.

Positioning the shutter signal outside the frame window will
result

in

an

error.

2.4.2

Variable Frame Rate – Programmable Integration

Variable frame rate mode provides the ability to run the camera in full
resolution and a frame rate slower than the nominal camera frame rate –
refer to Table 2.1. This has two effects: 1) it reduces the bandwidth
requirements on the Camera Link interface and 2) it increases the exposure
time for the frame. During normal camera operation, the nominal frame rate
determines the integration time. The desired frame rate, and thus the new
integration time, can be achieved by moving the vertical transfer pulse,
VCCD, beyond the normal integration period (the standard frame time) –
Figure 2.35. The resultant frame rate can be calculated using formula 4.1.
