Abstract:
A method of displaying a dynamic halftone image on a display panel made of pixels in accordance with dividing each frame of the image into subframes and turning on/off the subframes, comprising the steps of:finding a line of pixels that simultaneously display a specific intensity level in a frame and another specific intensity level in the next frame; calculating the sum &Dgr;S of stimulus on a retina to be produced with a weighted corrective pulse which will be applied to one of the n pixels, as follows: B1T&lsim;B2T+&Dgr;S&lsim;B3T, or B1T&gsim;B2T+&Dgr;S&gsim;B3T wherein T is a period in which the intensity level of ten pixels changes from one to another, B1 is an average of stimulus on a retina due to one of the n pixels before the change, B2 is an average of stimulus on the retina due to the same during the change, and B3 is an average of stimulus on the retina due to the same after the change; comparing the intensity levels with each other; selecting the weighted corrective pulses, which turn on/off corresponding subframes thereby to enable/disable corresponding intensity levels, respectively, according to the n pixels and a change in the intensity levels between the frames, so that the total sum of stimulus on the retina to be produced with the corrective pulses is substantially equal to n&Dgr;S; and adjusting original display signals for the n pixels according to the weighted corrective pulses respectively.
