PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of converting an inputted image to an image more natural than before at high speed.SOLUTION: A multifunction machine includes a storage unit for storing a representative color, and a controller for preparing a Voronoi diagram where the representative color stored by the storage unit is a generatrix on an Lab color space, and converting the respective pixels of the inputted image to the closest representative color on the basis of the Voronoi diagram. The controller receives a color selected by a user, and calculates one or more colors between the received color and white. The storage unit stores the color received by the controller as the representative color, and stores the color calculated by the controller as the representative color. The controller changes the representative color corresponding to the pixel (S223) so that the adjacent pixel is within a predetermined range on the Voronoi diagram. |
