Am I correct in thinking that dithering an image works in the following way:

I have a 2x2 image block consisting of individual pixels (x):

x  |  x
¬¬¬¬¬¬¬
x  |  x

I wish to dither the image via the following values:

3  |  4
¬¬¬¬¬¬¬
2  |  1

Therefore, will the 2x2 block appear as:

x x | x x
x   | x x
¬¬¬¬¬¬¬¬¬
x x | x 
    | 

Is this correct? If so, have I illustrated the dithered pixel layouts correctly?

Or am I completely mistaken? If so, could somebody kindly enlighten me (ideally with an example)?

I am aware that the sample size that I chose to use is a small one, but it was merely for illustration purposes.

Many thanks.

  • How did you reach this conclusion? Thanks. – tommy.carstensen Nov 09 '15 at 03:16
  • Seeing as I provided this answer approximately three-and-a-half years ago, I cannot remember the specifics but what I do remember is that I consulted with a PhD friend of mine who confirmed that this is correct. – Mus Nov 09 '15 at 13:54
