Abstract:
1. A method for displaying an image in which a halftone is reproduced by a subframe technique of converting a frame into a plurality of subframes, the method comprising: determining a lighting pattern that is a combination of on and off of the subframes for each of plural pixels of a display screen in accordance with a frame data value of a noted pixel, a lighting pattern of the noted pixel in a past frame and a lighting pattern determined for a peripheral pixel that is located in a vicinity of the noted pixel and has the same display color as the noted pixel, wherein: intensity values of Fourier components of the difference between the light emission waveform indicated by the lighting pattern in the past frame and a target light emission waveform indicated by the frame data value; and intensity values of Fourier components of a light emission distribution error between the peripheral pixel and the noted pixel are determined so that a sum of the intensities after being weighted becomes a minimum.
