A reference signal output section outputs a reference signal for each of the plurality of colors. A selection section selects a reference signal for each of the plurality of colors output from the reference signal output section in accordance with a light-emission timing of each of the plurality of semiconductor light-emitting elements. An operation control section, provided for each of the plurality of semiconductor light-emitting elements, holds an operation value fitted to a light-emitting characteristic of a corresponding semiconductor light-emitting element and converts the reference signal selected by the selection section by an operation.
