PROBLEM TO BE SOLVED: To provide a light emission performance controller capable of suppressing increase of a storage capacity for storing the light emission performance of an illumination device and increasing variations of the light emission performance.SOLUTION: A light emission performance controller includes: a light emission control data storage means for storing a gradation value for controlling the light emission luminance of a plurality of light emitting diodes in order to display prescribed performance control contents by an illumination device; a light emission driving means for causing the light emitting diodes to emit light using light emission-driving signals corresponding to the gradation value; a characteristic data storage means for storing two or more kinds of conversion characteristic data for converting the gradation value to the light emission-driving signals; and a characteristic selection means for selecting one piece of the conversion characteristic data from the two or more kinds of conversion characteristic data. The light emitting diodes are driven to emit light by using the conversion characteristic data selected by the characteristic selection means and using the light emission-driving signals corresponding to the gradation value stored in the light emission control data storage means. |
