1. A light emitting apparatus attachable to and detachable from an image pickup apparatus, the light emitting apparatus comprising:
a light emitting unit;
a processor configured to communicate with the image pickup apparatus and control the light emitting unit; and
a memory storing a first light emission amount of the light emitting unit,
wherein the processor has a first mode for causing the light emitting unit to emit light with the first light emission amount stored in the memory, and a second mode for causing the light emitting unit to emit the light with a second light emission amount acquired from the image pickup apparatus through communication,
wherein in a case where the processor receives a light emitting instruction in the second mode from the image pickup apparatus while the light emitting unit is emitting the light in the first mode, the processor causes the light emitting unit to emit the light with the second light emission amount in the second mode,
wherein in a case where the processor receives an end instruction in the second mode from the image pickup apparatus after the processor receives the light emitting instruction in the second mode from the image pickup apparatus while the light emitting unit is emitting the light in the first mode, the processor causes the light emitting unit to emit the light with the second light emission amount in the second mode and then the light emitting unit to emit the light with the first light emission amount in the first mode,
wherein in a case where the processor receives the light emitting instruction in the second mode from the image pickup apparatus while the light emitting unit does not emit the light in the first mode, the processor causes the light emitting unit to emit the light with the second light emission amount in the second mode, and
wherein in a case where the processor receives the end instruction of the second mode from the image pickup apparatus after the processor receives the light emitting instruction in the second mode from the image pickup apparatus while the light emitting unit does not emit the light in the first mode, the processor causes the light emitting unit to stop emitting the light.
