Operator FullRgbCamera

The operator transfers image data from a Camera Link FULL based RGB configuration camera into VisualApplets. Supported are three RGB modes. One mode, Tap8x8bit, is not standard conform.

[Important] Definition of "Tap"

The meaning of one tap, as used in this document, is one decoded color component of any bit width.

Note that in the CameraLink Specification Version 2.1, one tap is defined as one color pixel with all color components included.

The following table shows the mapping between the VA notation and the CameraLink Specification Version 2.1

VA notation CameraLink notation
Tap8x8bit ................ not covered by the CL Specification, used by selected cameras
Tap10x8bit .............. 8-Bit, 80-bit, RGB 10-tap
Tap8x10bit .............. 10-Bit, 80-bit RGB 8-tap

Table 46. Mapping VA notation and CL Specification Version 2.1


The following figures show the pixel mapping in these modes:

Tap8x8bit and Tap8x10bit:

Tap10x8bit:

The operator uses 2 ressources of type CameraPort exclusively. Thus, both ports of the frame grabber, port A (0) and port B (1), are occupied and cannot be used by other operators. The same ressource index can only be used once per applet.

Parameter BitWidth can be set to a larger or smaller value than the actual bitwidth sent by the camera.

If the parameter is set to a smaller value than the actual bitwidth sent by the camera, the least significant bits (LSB) of the pixel components are cut off. Only the most signicicant bits (MSB) per pixel component are transferred into VisualApplets.

If the parameter is set to a bigger value than the actual bitwidth sent by the camera, the original pixel components are set on the MSB position of the outgoing pixel components. The LSBs are filled with zeros.

In both cases, the relative brightness stays the same, i.e., white pixels remain withe and dark pixels remain dark.

Parameters

DvalMode
Type dynamic write parameter
Default DVAL_Enabled
Range {DVAL_Enabled, DVAL_Disabled}

The parameter specifies whether DVAL is used to mask valid pixels or if it is ignored. When DVAL is ignored, the valid pixels are selected according to LVAL and FVAL statuses.

FvalMode
Type dynamic/static write parameter
Default CameraLinkStandard
Range {CameraLinkStandard, IgnoreFval}
  • CameraLinkStandard

    The operator expects frame valid (FVAL) signals from the camera. In this case, the operator will output frames according to the FVAL size.

  • IgnoreFval

    If this setting is used, the operator will ignore any FVAL signals from the camera. All input lines will be used and merged into a sigle image with infinite height.

    [Note] Only available for Output Image Protocol VALT_IMAGE2D

    This parameter is only available if the output is set to image protocol VALT_IMAGE2D. If VALT_LINE1D is selected, the parameter is disabled and the FVAL is ignored anyway.

    [Warning] VisualApplets Link Rules Violation

    When the camera operator outputs a frame of infinite height, the Max. Img Height defined in the link properties might be exceeded. This causes a violation of the VisualApplets link rules. Ensure to use valid heights. Use operator SplitImage to limit the image height and split the endless image into multiple chunks.

The intention of this parameter is to allow the usage of area scan an line scan cameras dynamically in the same applet.

FullMode
Type dynamic write parameter
Default Tap8x8bit
Range {Tap8x8bit, Tap8x10bit, Tap10x8bit}

The parameter specifies the FULL configuration mode.

CameraStatus
Type dynamic read parameter
Default
Range

LightBridge/marathon: [0; 2^24-1]

mE5 VD8 ironman: [0;2^12-1]

Parameter CameraStatus depends on the frame grabber hardware you are programming for. Find below the descriptions first for marathon and Lightbridge, than for mE5 VD8-PoCL (ironman).

CameraLinkCoreReset
Type dynamic write parameter
Default 0
Range [0; 1]

Reserved for support issues.

PixelClockX
Type dynamic read parameter
Default 0
Range [0; 85] MHz

Pixel clock rate of camera channel X in MHz.

PixelClockY
Type dynamic read parameter
Default 0
Range [0; 85] MHz

Pixel clock rate of camera channel Y in MHz.

PixelClockZ
Type dynamic read parameter
Default 0
Range [0; 85] MHz

Pixel clock rate of camera channel Z in MHz.

MinimalParallelism
Type static read parameter
Default 3
Range [1; 1024]

Minimal parallelism for the output link O to be able to transport the maximal bandwidth of the camera without losing data. This value depends on the currently selected design clock frequency. The higher the frequency the lower the parallelism value can become.
