ABSTRACT:
A pixel modulation apparatus for converting pixel data D composed of N1bits to a pixel data signal composed of one bit. The pixel data D is input into the apparatus at a pixel period T0. The apparatus includes a first data conversion unit which converts the pixel data D to pixel data D1expanded to N2bits (N2>N1) at the period T0, a second data conversion unit which converts the pixel data D1to pixel data D2composed of N3/m bits at a period T0/m, a third data conversion unit which inputs n data from among the pixel data D2and pixel data Dd2constituting the pixel data D2before having the period T0/m to execute logical sum operations a predetermined number (equal to or less than n) of times to convert the n data to pixel data D3composed of N3bits, including additional data corresponding to the predetermined number, and a fourth data conversion unit which converts the pixel data D3to the pixel data signal composed of one bit at the period T0/m.
