2.3.1 1X-1Y Tap Geometry
After an image has been captured, the image is read out of the camera's imaging sensor and into
an image buffer. As pixel data is read out of the sensor and into the buffer, it is reordered so that the
pixel data for each line is in sequential ascending order from pixel 1 through the last pixel in the line.
When a camera is set for the 1X-1Y tap geometry, transmission of the pixel data from the camera's
image buffer to the frame grabber in the host PC will not begin until the entire image has been read
out of the sensor and buffered.
The 1X-1Y geometry
is a "one tap Camera Link configuration"

can be used, if the camera is set for either one tap sensor digitization or four tap sensor

digitization.
Figure 2 provides a graphical illustration of how the pixel data is transmitted from the image buffer
for 1X-1Y tap geometry. The text following Figure 2 provides a word description of how the pixel
data is transmitted.
The pixel clock is used to time data transmission. As shown in Figure 3 on
transmits data on each rising edge of the pixel clock.
