Try them both, and see how well they work with the image processing code.
Neither of them look ideal - the second one is fuzzy, the first one is 
vertically stretched. But perhaps it doesn't matter and they already 
work OK with the image processing code. If not, you have the option of 
writing some simple code to "unstretch" the first image (go row by row, 
reject a new row if it is too similar to the previous one, there is 
similar code in other drivers)
