Light-emitting apparatus, image pickup apparatus, and camera system capable of changing emission color temperature

摘要

A light-emitting apparatus which is capable of emitting light at desired emission color temperature even when aged deterioration of a light-emitting unit occurs. The light emitting unit has a plurality of LEDs that emit light in different colors, and is capable of changing emission color temperature of the light-emitting unit by changing the ratio of an amount light emitted by the LEDs. A emission color temperature of the light-emitting unit is set, and the light-emitting unit is flashed based on parameters corresponding to the set emission color temperature. Color temperature data on the image data is obtained based on image data obtained by performing image pickup by flashing the light-emitting unit based on the parameters. The parameters corresponding to the set emission color temperature are corrected based on the color temperature data on the set emission color temperature and the obtained color temperature data.
