||||||||||||||||||
![]() |
Pixel Bus In when Input Valid is TRUE, contains one of the following: valid pixel data, an end of line signal, or an end of image signal.
|
||||||||||||||||||
![]() |
Red Range determines the thresholding range for the green plane. Any pixels not included in this range are reset to 0 in the Pixel Bus Out.
|

![]() |
Input Valid specifies whether the next data point has arrived for processing. Wire the Output Valid output of an upstream node to this input to transfer data from the upstream node to this node. |
||||||||||||||||||
![]() |
Ready For Output specifies whether downstream nodes are ready for this node to return a new value. The default is TRUE. Use a Feedback Node to wire the Ready for Input output of a downstream node to this input of the current node.
