Lots of names, most of the pencil puzzles do. The first name I associated with that type was pic-a-pix. I might have come across a few unnamed before that time though. The Wikipedia page has the name as nonogram. The cross the streams variant has some extra rules, 1 contiguous region and no 2x2 full.
Oh, I honestly didn’t know it had a different name. Perhaps Picross is just the name for the video game version
