Abstract
A light-emitting element drive circuit system for driving a light-emitting element includes a current circuit section that drives the light-emitting element at a preset drive current value, and a current value setting section. The current value setting section sets the drive current value so that the drive current value is changed during a preset transition period from a first current value to a second current value that is not equal to the first current value, and changed during a preset transition period from the second current value to a third current value that is not equal to both the first current value and the second current value.
