A video signal level monitoring apparatus which monitors the level of a video signal, said apparatus comprises means for inputting a first color difference component (Cb) and a second color difference component (Cr) of a component video signal, means for inputting a luminance component (Y) of the component video signal as a luminance component (Y) of a composite video signal, means for generating a color component (C) of the composite video signal from the first color difference component and the second color difference component, and means for displaying each of the amplitude values of the color component (C) and the luminance component (Y) in a one-dimensional direction. Preferably, the display means displays each amplitude value in a bar graph display and scale marks corresponding to a minimum acceptable value and a maximum acceptable value within a range in accordance with a predetermined standard.
