LIGHT SOURCE APPARATUS AND METHOD FOR CONTROLLING SAME

摘要

A light source apparatus includes a light source, a detection unit configured to detect light emitted by the light source, a determination unit configured to determine a target brightness, and a control unit configured to periodically perform control of light emission from the light source, wherein the control unit divides one period of the control into a first period during which the light source is caused to emit light that is to be detected by the detection unit and a second period during which the light source is caused to emit light at the target brightness, and during the first period, drives the light source using a driving signal with a value smaller than a value during the second period, and the detection unit detects light emitted by the light source during the first period.

1. A light source apparatus comprising:
a light source; a detection unit configured to detect light emitted by the light source; a determination unit configured to determine a target brightness for the light source; and a control unit configured to periodically perform control of light emission from the light source, wherein the control unit divides one period of the control into a first period during which the light source is caused to emit light that is to be detected by the detection unit and a second period during which the light source is caused to emit light at the target brightness determined by the determination unit, and during the first period, drives the light source using a driving signal with a value smaller than a value during the second period, and the detection unit detects light emitted by the light source during the first period.
