Video Format (Simulation)

Toolbar:

Menu:   Acquire > Video Format

Script:   setVideoFormat

Use this command to select the video format for the simulation video driver. If you choose this command, the Video Settings dialog box will appear with the following options:

Pixel Format

Use the drop-down list to select the image type for the Blank input mode of the Video Source. Choose among the following types:

Grayscale (8 bit)

Grayscale (16 bit)

RGB (24 bit)

RGB (32 bit)

RGB (48 bit)

See Image Types for more details. Note that if the video input mode is set to File, this option will be unavailable.

Image Size

Lets you choose the size of the video frames for the Blank input mode of the Video Source. To change the horizontal and vertical size of the video frames, type the desired values in the boxes below and press ENTER. Note that if the video input mode is set to File, this option will be unavailable.

Pedestal

Lets you indicate the constant level of luminance that will be added to the input signal. If the input source image is of the grayscale type, enter the desired Luminance level in the corresponding box. The level should be given in percentage of the maximum pixel value, which is 255 for 8-bit images and 65535 for 16-bit images. If the input source image is of the color type, enter the desired pedestal levels for each color component in the Red, Green, and Blue boxes.

Nonuniform background

Lets you simulate uneven lighting conditions for a point light source aligned with the center of the image.

Select Enable to turn on the nonuniform background simulation.

Enter the Distance between the light source and the surface of the image. The distance should be given in percentage of the horizontal size of the image.

As the light source moves away from the image surface, its simulated brightness will increase in order to keep the intensity in the central point of the image unchanged.

Delay

Lets you choose the simulated frame rate by indicating the interval between the frames in milliseconds. Note that if you select an animation or sequence file as a video input, the Delay will be automatically set to the frame interval with which the selected file was recorded. Changing this option will override the original frame rate of the video file.
