FIELD: information technology.
SUBSTANCE: secondary video signal is generated, said signal being composed of signals having values derived via conversion of intermediate values into values lying inside an output range according to a predetermined conversion rule when intermediate brightness values (determined by formulas 
where Smin is the output value of the lower limit, Xr to Xb are values of RGB signals of the main video signal, k is a constant, and Lr to Lb are intermediate values of RGB brightness), include a value greater than the value of the upper output limit, otherwise a secondary video signal consisting of a signal having an intermediate brightness value is generated.
EFFECT: preventing gradation error when a given video signal shows colour in a region outside the colour range of the video display element, performing signal conversion processing with low arithmetic load.
