5.3.1. Parameters

The camera configuration parameters may be interactively changed.

Exposure Time: the camera exposure may be adjusted. The value is in microseconds with

increments of 1 microsecond.

Contrast and Brightness: the contrast and brightness of the image produced by the camera

may be adjusted. The values range from –100 to 100.

Binning: the user may select the binning mode from 1x1 to 4x4. In this fashion pixels may be

grouped to form a larger pixel, which results in added SNR and sensitivity. When this

parameter is changed, the Region of Interest (ROI) is reset. The control is disabled when the

camera is playing.

Pixel Format: the camera digitizer is a 12-bit digitizer. The output can be 8-bit (Gray8) or 10-

bit (Gray16) (12-bit for 1500-EX camera model). The control is disabled when the camera is

playing.

Readout Frequency: this parameter controls the speed at which the image data is read from

the CCD. The supported values are: 20 MHz, 10 MHz, 5 MHz and 2MHz.

Exposure Mode: the camera exposure may be single or double.

Trigger Mode: the default state of the camera at start-up is in the Internal/continuous mode.

In this mode the camera does not require a trigger input signal. The other camera modes

(External Edge High, Edge Low, Pulse High and Pulse Low) require an external trigger input.

In these modes the camera waits for a trigger signal to initiate the acquisition of a frame.

There is a delay (latency) between the trigger event and the start of an acquisition of 12

microseconds.

Camera Cooler: the camera cooler feature may be activated. The parameter enables and

disables the thermoelectric-cooler.

Acquisition Time Out: the acquisition and snap time out may be configured. The value is in

seconds.

Region of interest: the camera ROI may be adjusted. The grayed edit boxes in the ROI

group show the current ROI settings. The user may change them by pressing the "Edit…"

button (see below). The button is disabled when the camera is playing.

5.3.2. Zoom Group

The way the preview window image is displayed may be adjusted.

Zoom: the image zoom may be adjusted. If the image is bigger than the preview window, the

user may drag to pan over the image.

Fit to Window: if the check box is checked the image is automatically zoomed so that it fits

on the current display window. The zoom combo box is disabled.
