A color signal converter comprises first and second color conversion tables for storing color conversion data that correspond to different external conditions; and a color conversion table data interpolation section for generating, based on color conversion data outputted from the first and second color conversion tables and external conditions, color conversion data for image generation that correspond to external conditions. In the event of change in the external temperature conditions, a color conversion table is generated by interpolating the first and second color conversion tables, which are provided for different conditions, according to the current external temperature conditions. Color reproducibility is thus unaffected by external conditions and optimum color conversion can always be achieved.
