Abstract:
1. A method for driving an image display apparatus comprising: (A): an image display panel including (B): a signal processing section configured to generate a first sub-pixel output signal, a second sub-pixel output signal and a third sub-pixel output signal for respectively said first, second and third sub-pixels, whereby said signal processing section provides a fourth sub-pixel output signal on the basis of a first sub-pixel input signal, a second sub-pixel input signal and a third sub-pixel input signal wherein, with a notation p denoting a positive integer satisfying a relation 1≦p≦P, a notation q denoting a positive integer satisfying a relation 1≦p≦Q, a notation p 1 denoting a positive integer satisfying a relation 1≦p≦P, a notation p 2 denoting a positive integer satisfying a relation 1≦p≦P, notation P denoting a positive integer representing the number of said pixel groups laid out in said first direction and notation Q denoting a positive integer representing the number of said pixel groups laid out in said second direction: with regard to said first pixel pertaining to a (p, q)th pixel group, said signal processing section receives with regard to said second pixel pertaining to said (p, q)th pixel group, said signal processing section receives with regard to said first pixel pertaining to said (p, q)th pixel group, said signal processing section generates with regard to said second pixel pertaining to said (p, q)th pixel group, said signal processing section generates with regard to a fourth sub-pixel pertaining to said (p, q)th pixel group, said signal processing section generates a fourth sub-pixel output signal provided with a fourth sub-pixel output-signal value X wherein said first signal value SG (p, q)−1 is determined on the basis of a first minimum value Min (p, q)−1 whereas a second signal value SG (p, q)−2 is determined on the basis of a second minimum value Min (p, q)−2 where said first minimum value Min (p, q)−1 is the smallest value among said three sub-pixel input-signal values x 1−(p1, q) , x 2−(p1, q) and x 3−(p1, q) whereas said second minimum value Min (p, q)−2 the smallest value among said three sub-pixel input-signal values x 1−(p2, q) , x 2−(p2, q) and x 3−(p2, q) said first sub-pixel output-signal value X 1−(p1, q) is found on the basis of at least said first sub-pixel input-signal value x 1−(p1, q) , said first maximum value Max (p, q)−1 , said first minimum value Min (p, q)−1 and said first signal value SG (p, q)−1 ; said second sub-pixel output-signal value X said third sub-pixel output-signal value X said first sub-pixel output-signal value X said second sub-pixel output-signal value X said third sub-pixel output-signal value X where said first maximum value Max
