The max. level and min. level which are the reference at the time of the A/D conversion of the signal RS can be set at the reference potential VHR of the high side and the reference potential VLR of the low side by varying the variable resistors RHR and RLR. The same holds true of the signals GS, BS. The min. and max. transmittances are thus maintained at the same level by independently setting the reference potentials of the A/D converters in such a manner. The nonuniformity of the colors is thereby relieved and the good-quality images are obtd.
