Abstract
A light-emitting device including a light-emitting element and causing the light emitting element to emit different light amounts. The light-emitting device includes: a measurement unit, a predetermined value storage unit, and a driving signal calculation unit. The measurement unit measures a surrounding temperature of the light-emitting element. The predetermined value storage unit stores a predetermined value of a driving signal for causing the light-emitting element to emit light. The driving signal calculation unit executes calculation of a value of the driving signal for causing the light-emitting element to emit a desired light amount by applying a correction factor in accordance with the measured surrounding temperature and the desired light amount to the predetermined value of the driving signal.
