Morphology
The censoring meaning is directly derivable from combining 'black' (to darken/obscure) with 'out' (completely/away from view): making text or images black so they are not visible is a literal compositional action. This motion/covering pattern is common and cross-linguistically transparent, so a B1 learner who knows the constituents would likely understand this sense (though the verb also has other senses like losing consciousness).
Etymology
Black out comes from the time during a war when people covered windows and turned off all lights so the whole town was very black and all lights were out, making it hard for enemy planes to see. That's why black out means 'to make a place completely dark'.
