<P>PROBLEM TO BE SOLVED: To accurately correct ghosting of a display apparatus that uses a light emitting element. <P>SOLUTION: A conversion efficiency degradation value calculation section 233 calculates a conversion efficiency degradation value regarding degradation of conversion efficiency of converting a driving current into luminance based on information regarding the degradation of conversion efficiency generated according to the lapse of light emission time of the light emitting element. A current amount degradation value calculation section 333 calculates a current amount degradation value based on information regarding the degradation of the driving current generated according to the lapse of light emission time of the light emitting element. A correction calculation unit 340 corrects a gradation value of an image signal to be input to a pixel circuit based on the conversion efficiency degradation value and the current amount degradation value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
