Sample Rate

The Sample Rate specifies the rate at which images are to be recorded. The s rate is

depended upon the defined Resolution, (width-to-height ratio), of the images being

captured.

For actual Sample Rates refer to: Functional Descriptions>Frame Rate Tables.

Exposure Time

The default setting is nominally, the reciprocal of the sample rate less 20 microseconds of

overhead. Click the down-arrow to display a drop down list box and select one of the preset

exposure times in the pull down list box. If the desired exposure time is not listed an

exposure time may be entered. The Phantom Camera Control application allows the end-

user to enter exposure times in one-microsecond increments between the minimum and

maximum exposure time in the drop down list.

EDR

The EDR, (Extreme Dynamic Range), exposure time feature is very useful when the subject

contains very bright areas as well as darker areas and both must be exposed properly

throughout the cine file. The EDR function permits the end-user to expose for darker areas

in the subject via the Sample Rate and Exposure time settings and then set a separate and

independent pixel level EDR exposure for all the portions of the image that might become

saturated, (over exposed). The EDR feature is automatically enabled when any value, other

than zero, is entered in the EDR Exposure field.

NOTE

EDR Exposure times should be set at approximately 1/2 of the Exposure time as a starting

point. By setting the EDR Exposure to 1/2 of the Exposure time the brightest pixels in the

images will be exposed for one stop less than the darker pixels.

The EDR feature cannot be used in conjunction with the Auto Exposure feature and should

not be enabled while performing a CSR, (Current Session Reference), or Black Reference

calibration adjustment.

Low Light Button

Using the Low-Light feature automatically sets the camera exposure to a pre-defined level.

This exposure level is based on the camera's resolution and sample rate settings.

Trigger Position

The Post Trigger parameter sets the number of images or frames to be saved after a trigger

has been detected. Setting the number of post trigger images also determines the reciprocal

number of pre-trigger images saved.

Post Trigger Slider

Sets the number of images or frames to be saved after a trigger has been detected and

automatically changes the value in the Post Trigger entry box. Moving the slider to the left

increases the number of post trigger frames, while sliding it to the right will reduce the

number of post trigger frames.
