An organic EL display device which displays by individually controlling an amount
of current of organic EL elements, which are arranged in a matrix, according to
an input image signal, comprising:
- a lookup table for storing gamma compensation data for compensating
an image signal;
- storage means for storing an equation for performing gamma compensation
of the input image signal; and
- table data generation means for generating table lookup data and storing
such data in the lookup table on the basis of the equation stored in the storage
means, and wherein the table data generated by the table data generation means
is stored in the lookup table by an initialization operation to perform gamma compensation
of the input image signal.
