Image display method and image display apparatus

摘要

There is described an image display apparatus that includes an image data processing section to convert (n+m)-bit monochromatic image data to a n-bit color display image-data group, based on a predetermined correlation, and a color image display section to display a color image on it, based on the n-bit color display image-data group. The image data processing section includes: a candidate selection section to select “H” sets of signal-values out of all combinations of signal-values included in the n-bit color display image-data group as the candidate color display signal-value sets; a signal value decision section to determine a color display signal-value set, to be correlated with the (n+m)-bit monochromatic image data, from among the “H” sets of candidate color display signal-value sets; and a correlation establishing section to establish the correlation between the (n+m)-bit monochromatic image data and the n-bit color display image-data group.
