Image display device

A method to perform black-correction of an image data for display to an image display device, comprising the steps of:

• performing a black correction processing of correcting a black reproducibility of an image data containing a predetermined number of color data, to output black-corrected image data;
• and
• performing an image display on a predetermined screen based solely on said black-corrected image data,
• the step of performing the black correction processing including the step of
• performing a predetermined operation to specify a black-display characteristic specifying data related to a characteristic in displaying black with the step of performing an image display;
• calculating a black-approximated data composed of said predetermined number of color data and related to luminance and at least one of chromaticity and tristimulus values in displaying black based on said characteristic in displaying black with the step of performing an image display on the basis of said black-display characteristic specifying data;
• and
• executing said black correction processing to said image data in units of said predetermined number of color data based on said black-approximated data, to output said black-corrected image data.

An image display device, comprising:

• a black correction part performing a black correction processing of correcting a black reproducibility of an image data containing a predetermined number of color data, to output black-corrected image data;
• and
• an image display means performing an image display on a predetermined screen based solely on said black-corrected image data,
• said black correction part including:
• a black-display characteristic specifying means performing a predetermined operation to specify a black-display characteristic specifying data related to a characteristic in displaying black with said image display means the characteristic being based on data input from an image display user;
• a black-approximated data calculating means calculating a black-approximated data composed of said predetermined number of color data and related to the data input from the image display user and at least one of luminance, chromaticity and tristimulus values in displaying black based on said characteristic in displaying black with said image display means on the basis of said black-display characteristic specifying data;
• and
• a black-correction processing executing means executing said black correction processing to said image data in units of said predetermined number of color data based on said black-approximated data, to output said black-corrected image data.
