Operator CameraGrayAreaBase

Operator Library: Hardware Platform

This operator represents the image data interface between a grayscale area scan camera in Camera Link base configuration mode and VisualApplets. This operator requires one VisualApplets resource of type CAM. Set the resource index for the camera in the resource dialog. The resource index 0 maps the camera to port A and the resource index 1 maps to the camera to port B. Check 'Allocation of Device Resources' for more information.

This operator can be configured to support different data formats specified by the CamerLink standard. Use parameter Format to set the camera operator to the same mode as used by the camera.

The parameterized format is converted to match with the output link format of the camera operator. The output link can be configured to several bit widths. Conversion is performed by adding bits to the lower bit positions if the camera format bit width is higher than the parameterized bit width in the output link. However, if the camera format bit width is less than the available bits at the output link, only the most significant bits are used.

Moreover, in the output link the maximum possible image dimensions have to be specified. The size of the actual transfered images however may be less but must not exceed this parameterized maximum.

Parameters

UseDval
Type dynamic read/write parameter
Default DVAL_Enabled
Range {DVAL_Enabled, DVAL_Disabled}

By setting this parameter to DVAL_Disabled it is possible to support cameras which do not fully comply with the CameraLink specification. In disabled mode, control signals Lval and Fval are used to decode pixels. In enabled mode, the additional DVAL signal is used. In general users should not modify this parameter!

Format
Type dynamic read/write parameter
Default SingleTap8bit
Range {SingleTap8bit, SingleTap10bit, SingleTap12bit, SingleTap14bit, SingleTap16bit}

This parameter specifies the data format of the connected camera. The format has to match with the camera configuration.
