PROBLEM TO BE SOLVED: To accurately correct ghosting of a display apparatus which uses a light-emitting element.SOLUTION: A conversion efficiency degradation characteristic production unit 450 produces conversion efficiency degradation characteristics based on a result obtained by measuring a dummy pixel circuit at a specified current. A conversion efficiency degradation information integration unit 220 produces conversion efficiency degradation information by using the conversion efficiency degradation characteristics. A conversion efficiency degradation correction pattern production unit 230 produces a conversion efficiency degradation value by using the conversion efficiency degradation information. A current amount decrease characteristic production unit 480 produces current amount decrease characteristics based on results obtained by measuring the dummy pixel circuit at the specified current and measuring it at a driving current. A current amount decrease information arithmetic unit 240 produces current amount decrease information by using the current amount decrease characteristic. A current amount decrease correction pattern production unit 250 produces a current amount degradation value by using the current amount decrease information. A correction arithmetic unit 260 corrects a gradation value of an image signal to be input to the pixel circuit based on the conversion efficiency degradation value and current amount degradation value.
