| Zusammenfassung: | A light source driving device 20 according to an embodiment includes a storage unit 202 that stores therein three or more combinations of a level indicating brightness of light emitted from a light source 301, and a control value used when light with brightness corresponding to the level is emitted from the light source 301, the control value having a nonlinear relation with the level; and a control unit 203 that controls the light source 301 so that the brightness of the light emitted from the light source 301 is gradually changed to brightness corresponding to a level indicated by a light control instruction signal to be supplied, by using two or more combinations among the combinations stored in the storage unit 202. |
