Patent ID: 7110001

Claim:
A correction characteristic determining device for determining a correction characteristic in a display device which corrects an image signal constituted of three primary color signals, and displays a color image in display means in accordance with thus corrected image signal, said correction characteristic determining device comprising: data converting means for converting measured data, convertible into a tristimulus value, that indicates a result of measurement performed with respect to an emission condition of display in the display means, into brightness data of three primary colors, by using a conversion matrix; correction characteristic determining means for determining the correction characteristic in accordance with a conversion result obtained by the data converting means; and matrix generating means for generating the conversion matrix, wherein said matrix generating means includes: matrix element generating means for generating a matrix element of an inverse matrix of the conversion matrix, in accordance with measured data obtained when the display means displays highest gray scales of respective primary colors; matrix element adjusting means for adjusting a matrix element that has been generated by the matrix element generating means in accordance with measured data obtained when the display means displays a highest gray scale of white; and inverse matrix generating means for generating an inverse matrix of a matrix constituted of the matrix element that has been adjusted.
