Abstract:
An image processing method comprising the steps of:selecting one output device from a plurality of different types of output devices, at least two of the types of output devices having respectively different tonality characteristics on multi-level data, wherein each of the multi-level data is represented by a plurality of bits;selecting, from a plurality of conversion tables stored in advance, a conversion table which is used for converting multi-level data and that corresponds to the type of the selected output device;converting values of input multi-level data represented by a plurality of bits into corresponding values of output multi-level data represented by a plurality of bits using the selected conversion table, the selected conversion table causing the output multi-level data to be reproducible by the selected output device as an image of high tonality; andoutputting the output multi-level data to the selected output device to be reproduced as the image of high tonality.
