An illumination apparatus includes a first target portion including a light source, a second target portion different from the light source, and a processor configured to function as a light emission control unit, a calculation unit, and a control unit. The light emission control unit is configured to control a light emission operation of the light source. The calculation unit is configured to, based on heat generated by the light emission operation of the light source, calculate a first control temperature and a second control temperature. The control unit is configured to control the light emission operation. The calculation unit calculates the first control temperature based on a first influence degree of the heat generated by the light emission operation and calculates the second control temperature based on a second influence degree of the heat generated by the light emission operation different from the first influence degree.
