LIGHT SOURCE DEVICE, LIGHTING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a light source device, a lighting method and a program capable of suppressing light amount variation resulting from individual differences between light-emitting diodes and also capable of stabilizing the amount of irradiation light.

SOLUTION: A light source device 10 comprises: light-emitting parts L1 to Ln having one or more light-emitting diodes: a light-receiving unit 20 which receives irradiation light irradiated from each of the light-emitting parts and outputs signals identifying the amount of irradiation light thus received; and a control unit 40. The control unit 40 carries out: an alternate lighting process for alternately turning on each of the light-emitting parts; and a light amount correcting process for individually turning on each of the light-emitting parts and identifying the amount of irradiation light irradiated by the light-emitting parts based on the signals thus output from the light-receiving unit to thereby determines, based on the identified light amount, the value of current to be supplied to the light-emitting parts during the alternate lighting process.
