Video Display (Simulation)

Toolbar:

Menu:   Acquire > Video Display

Use this command to adjust the video display settings for the simulation video driver. If you choose this command, the Video Settings dialog box will appear. Click the Video Display tab, and you will see the following options:

Sync

Lets you adjust the setting for the "lost of synchronization" mode:

StepX – the horizontal shift of the image per frame in pixels. Positive or negative values will make the picture slide to the right or left respectively.

StepY – the vertical shift of the image per frame in pixels. Positive or negative values will make the picture slide down or up respectively.

Sine

Lets you adjust the setting for the sinusoidal noise:

Amplitude – the amplitude of the sine signal. Increasing this value will cause larger variations in the signal.

Wavelength – the wavelength of the sine wave in pixels. The larger this value is, the longer the distance between adjacent crests in the wave will be.

Angle – the orientation of the sine wave to the horizontal. The angle must be given in degrees counterclockwise.

Color – the color code of the sine signal. Select one of the following colors: 1 –red, 2 – green, 3 – yellow, 4 – blue, 5 – magenta, 6 – cyan, 7 – white. Note that this parameter has no effect on the grayscale image.

Noise

Lets you adjust the setting for the white noise simulation.

Level – the maximum level of the noise. This value is given in percentage of the maximum pixel value for the current image type.

Density – the spatial density of the noise in relative units.

Pulse

Lets you adjust the setting for the temporal intensity pulsations.

Level – the maximum level of the pulsations. This value is given in percentage of the maximum pixel value for the current image type.

Rate – the temporal rate of the pulsations in relative units.
