Patent ID: 7545393

Claim:
A method of determining correction values for driving a plurality of display elements for displaying an image, comprising: a step of acquiring data having a correlation to luminance by driving a display element in accordance with image data for measuring; a step of performing conversion of the acquired data having the correlation to luminance into spatial frequency data comprising low-frequency components in a passage region and high-frequency components out of the passage region, wherein the passage region is a low-frequency range in which it is difficult for human eyes to discriminate luminance unevenness; a step of acquiring spatial frequency components of luminance target values, by reducing low-frequency components of the spatial frequency data and setting the high-frequency components of the spatial frequency data to 0; a step of acquiring luminance target values by performing an inverse conversion of the conversion on the spatial frequency components of the luminance target values; and a step of calculating a correction value for driving the display element, on the basis of the luminance target value.
