Abstract
A density curve is derived from a plurality of known output data values and a plurality of density values which are obtained by the known output data values. Then, a desired gamma correction curve is formed in accordance with the thus derived density curve. Finally the thus formed gamma correction curve is finely adjusted in accordance with a desired correction curve which is selected from a plurality of previously prepared correction curves. In order to simplify the data entering operation, a small number of data values are entered and then an interpolation is performed to obtained a necessary number of data values. The gamma correction curve is formed only when the apparatus is installed, the property of the developing solution is changed or the record film is changed. In this manner, the optimal gamma correction curve can be simply and directly formed.
