PROBLEM TO BE SOLVED: To drive a self-light emitting display unit at a non-interlace scanning mode from a video signal generated by interalace scanning while high picture quality is maintained by executing two different picture processings on a pair of picture element data obtained by sampling, obtaining picture processing picture element data and interpolation picture element data and setting them to be picture driving data of odd/even lines. SOLUTION: An A/D converter 1 samples the inputted video signal and supplies corresponding picture element data at every picture element to a picture data processing circuit 3. The picture data processing circuit 3 processes picture element data, reduces the number of bits of picture element data, realizes pseudo intermediate display, generates picture element data compensating a pseudo outline and supplies it to a frame memory 4. The memory 4 sequentially writes picture data outputted from the processing circuit 3, reads them in accordance with timing and supplies them to a column electrode driver 6 as picture element driving data. |
