Abstract
An image information processing method comprises a step of generating electrical color image signals representative of the quantities of light of separated colors from an object, and a step of converting the generated color image signals to signals with values substantially proportional to the cubic root of the quantities of light from the object with respect to the respective separated colors. The method comprises a step of adjusting recording gradation characteristics of respective colors to be recorded such that the values of color image signals to be recorded are substantially proportional to the cubic root of recorded reflectivities, respectively, and a step of determining recording gradations of the respective colors in accordance with the color image signals by using the adjusted recording gradation characteristics.
