Figure 5.11 shows how the value stored at one pixel position in a memory bank is mapped to the corresponding position on the TV monitor display.

This process is repeated for each required pixel position in the transformed image.

An alternative method iteratively computes the undistorted pixel position.

In motion estimation an exact 1:1 correspondence of pixel positions is not a requirement.

This means that for every pixel position a separate measurement is taken for red then green then blue.

Similar calculations are carried out to determine pixel positions along a line with negative slope.

The image displayed on the screen is taken as samples, at each (x,y) pixel position, of a filtered version of the signal.

So a scan line beginning with $03 would have the first two pixel positions set as white (with the next 5 pixels black).

So that not even a mouse logger can log the pixel position of the click on the screen for use again later.

There was no signal at all in the missing pixel positions.
