Judging from their descriptions (in include/sane/saneopts.h), nothing save for the command-line option names. I think this is just a case of independently developed backends where developer picked different option names for the same thing. A patch is welcome but note that it would break backward compatibility for a bunch of unmaintained backends if you simply drop the black- and white-level options :-o # The right way to go about this is *add* shadow and highlight to those # backends, mark the black-level and white-level options deprecated and # drop them in some release after the next. FWIW, the version 2 draft of the standard documents shadow and highlight at https://sane-project.gitlab.io/standard/draft-2/api.html#shadow-option https://sane-project.gitlab.io/standard/draft-2/api.html#highlight-option so keeping that option is probably to be preferred.
