Abstract
A color signal correction circuit for correcting a color signal which displays data on each pixel of a display apparatus, comprising: a color signal input section for inputting a color signal of N bits (N is a natural number); an addition section for adding second and third color signals corresponding to first and second adjacent pixels which are adjacent to the predetermined pixel to obtain addition value data; a first comparison section for subtracting duplicated color signal data, which is obtained by duplicating a first color signal corresponding to the predetermined pixel, from the addition value data to obtain a difference value; a LSB determination section for determining an LSB according to the difference value; and a color signal generation section for adding N higher order bits of the duplicated color signal data and the LSB, so as to generate a color signal of (N+1) bits.
