Abstract:
1. An image correction apparatus that corrects images displayed by a plurality of image display apparatus, the images arranged contiguously or superimposed, the image correction apparatus comprising: a correction reference value generator that generates a correction reference value, the correction reference value being a reference display characteristic common to each of the plurality of image display apparatus, and the correction reference value being generated based on display characteristics of the plurality of image display apparatus; a correction data generator that generates correction data for each of the image display apparatus, the correction data used to correct pixel values in such a way that the display characteristic of each of the image display apparatus using the corrected pixel values is equivalent to the correction reference value; and a correction amount adjuster that adjusts an amount of correction in such a way that, when the corrected pixel values obtained by using the amount of correction to correct the pixel values are larger than a given maximum pixel value, a hue and chroma of the pixels that correspond to the corrected pixel values coincide with a hue and chroma determined from the correction reference value and the corrected pixel values are smaller than or equal to the maximum pixel value.
