PROBLEM TO BE SOLVED: To reduce color irregularities in a joining portion of heads. SOLUTION: The liquid ejection device includes: a first head which includes a plurality of nozzles for ejecting a liquid arranged in a predetermined direction; a first color conversion table which is for converting a tone value of a first color space of a pixel to which the liquid is ejected from the first head, to a tone value of a second color space corresponding to a color of the liquid; a second head which includes a plurality of nozzles for ejecting the liquid arranged in the predetermined direction, the second head at least partially overlapping the first head in the predetermined direction; and a second color conversion table which is for converting the tone value of the first color space of a pixel to which the liquid is ejected from the second head, to the tone value of the second color space. A third color conversion table is created based on the first and second color conversion tables, for a pixel of an overlapping portion to which the liquid is ejected from the first and second heads, a tone value of the first color space is converted to a tone value of the second color space according to the third color conversion table.
