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

An image pickup apparatus that has a light-emitting unit comprising a plurality of light-emitting devices that emit light in different colors, and is capable of changing emission color temperature of the light-emitting unit by changing a ratio of an amount light emitted by the plurality of light-emitting devices, comprising:

• an image pickup unit configured to perform image pickup and output image data;
• a setting unit configured to set an emission color temperature of the light-emitting unit;
• a light emission control unit configured to flash the light-emitting unit based on parameters corresponding to the emission color temperature set by said setting unit;
• an obtainment unit configured to, based on image data obtained by performing image pickup by flashing the light-emitting unit based on the parameters corresponding to the emission color temperature set by said setting unit, obtain color temperature data on the image data;
• and
• a correction unit configured to correct the parameters corresponding to the emission color temperature set by said setting unit based on the color temperature data on the emission color temperature set by said setting unit and the color temperature data obtained by said obtainment unit.
