<strong>JAI</strong> Proprietary vs. <strong>GenICam</strong> <strong>SFNC</strong> <strong>camera</strong> settings<br />

SequentialEPSTrigger Sequential EPS trigger Same as EdgePreSelect mode but this is only<br />

used in conjunction with the <strong>JAI</strong> “Sequence<br />

Trigger” mode.<br />

used in conjunction with the <strong>JAI</strong> “Sequence<br />

Table 1 – <strong>JAI</strong> Exposure Modes<br />

St<strong>and</strong>ard trigger mode where an external or<br />

internal trigger signal will start the exposure.<br />

The exposure time is predetermined by the<br />

current ShutterMode setting. The readout of<br />

the image is controlled by an additional<br />

Camera Trigger signal.<br />

St<strong>and</strong>ard trigger mode where an external or<br />

internal trigger signal will start the exposure.<br />

The exposure time is controlled by the amount<br />

of time the trigger signal is held active. The<br />

readout of the image is controlled by an<br />

additional Camera<br />

Trigger signal.<br />

Triggered mode where the <strong>camera</strong> is exposing<br />

continuously until a trigger signal is received.<br />

When the trigger signal is received the<br />

continuous capture will be reset <strong>and</strong> the<br />

exposure of a single frame will be started. The<br />

exposure time is predetermined by the current<br />

ShutterMode setting. This mode is essential if<br />

the <strong>camera</strong> has built-in auto-exposure feature<br />

where the iris of the lens is controlled by the<br />

<strong>camera</strong>.<br />

The readout of the image is controlled by an<br />

additional Camera Trigger signal.<br />

The “ExposureMode” feature can be set from <strong>JAI</strong> SDK using the following comm<strong>and</strong>:<br />

J_Camera_SetValueString(hCamera,“ExposureMode”,);<br />

Where the is a string taken from the <strong>GenICam</strong> feature name<br />

column from the table above.<br />

From the <strong>JAI</strong> Camera Control Tool the Exposure Mode value can be selected using the drop-down box<br />

as shown in the following figure:<br />
