Table 5.4: Explanation of control and data signals used in the timing diagram
These terms will be used also in the timing diagrams of Section 5.4.
5.3 Read-out Timing
Frame time is the inverse of the frame rate.
Period during which the pixels are integrating the incoming light.
Pixel clock on CameraLink
Internal signal, shown only for clarity. Is 'high' during the exposure
time.
Is 'high' while the data of one complete frame are transferred.
Is 'high' while the data of one line are transferred. Example: To transfer
an image with 640x480 pixels, there are 480 LVAL within one FVAL active
high period. One LVAL lasts 640 pixel clock cycles.
Is 'high' while data are valid.
Transferred pixel values. Example: For a 100x100 pixel image, there are
100 values transferred within one LVAL active high period, or 100*100
values within one FVAL period.
Delay before the first line and after every following line when reading
out the image data.
