Early on in this project the inclusion of conversion from 16:9 to 4:3/5:4 was discussed. At the time I did some calculations but decided to leave trying it until the end at which time I would know what resources I had left over. Well it sorta got forgot about. Well that was until forum member Doz built a converter and wrote a blog about building it (here). In the blog he raised the question about 16:9 to 4:3/5:4 conversion.
So I decided to give it a go. It is a straight forward crop the beginning and ends off each line.
The results are shown in the photos below which show how the picture is stretched for the different combinations of input/output.
This is just the first stage. There is some tweaking to be done and some niggles to be got rid of.
I am glad now that I have those extra DIP switches
. I will be able to make use of them for this extra function. Both for the function itself and to select if it is available on the front panel or on a DIP switch.
