Abstract
A color image processing apparatus realizes color reproduction in a color image output apparatus by controlling the total amount of coloring material used while making full use of the color reproduction range of the color image output apparatus. To this end, a signal C′M′Y′K′, obtained after a &ggr; conversion (gamma conversion), is converted into an amount of ink drops V (CMYK) at a conversion unit. Then, at a total ink drop quantity control unit, a total ink quantity of the amount of ink drops converted at the conversion unit and a limit value (maximum total ink drop quantity) stored in a maximum total ink quantity memory unit are compared, and the total ink quantity is controlled to be lower than the limit value. Then, the controlled amount of ink drops is converted into a recording control signal C″M″Y″K″ at a control signal conversion unit.
