Abstract

There is provided a light-emitting device including a wireless communication unit that performs wireless communication with another device, a light-emitting unit that emits light, and a control unit that performs control by switching between a mode in which the light emission of the light-emitting unit is controlled in accordance with a timing at which a signal is received by the wireless communication unit and a mode in which the light emission of the light-emitting unit is controlled in accordance with an internal timer based on a light emission timing included in a signal received from the other device by the wireless communication unit.

Claims

1. A light-emitting device comprising:

a wireless communication unit that performs wireless communication with another device;

a light-emitting unit that emits light; and

a control unit that performs control by switching between a mode in which the light emission of the light-emitting unit is controlled in accordance with a timing at which a signal is received by the wireless communication unit and a mode in which the light emission of the light-emitting unit is controlled in accordance with an internal timer based on a light emission timing included in a signal received from the other device by the wireless communication unit.

2. The light-emitting device according to claim 1, wherein the control unit controls the light emission of the light-emitting unit in accordance with the timing at which a signal is received by the wireless communication unit when a light emission period included in the signal received from the other device is equal to or greater than a predetermined value, and the control unit controls the light emission of the light-emitting unit in accordance with the internal timer when the light emission period is less than the predetermined value.

3. The light-emitting device according to claim 1, wherein the control unit controls the light emission of the light-emitting unit by fade-in or fade-out.

4. The light-emitting device according to claim 1, further comprising:

an operational input unit that receives an input operation,

wherein the control unit controls the light emission of the light-emitting unit in accordance with an input to the operational input unit when the wireless communication unit does not receive a signal from the other device.

5. A method of controlling a light-emitting device, comprising:

performing wireless communication with another device;

determining a light emission period included in a signal received from the other device;

controlling light emission of a light-emitting unit in accordance with a timing at which a signal is received through wireless communication when the light emission period is equal to or greater than a predetermined value; and

controlling the light emission of the light-emitting unit in accordance with an internal timer when the light emission period is less than the predetermined value.

6. A program for causing a computer to execute:

performing wireless communication with another device;

determining a light emission period included in a signal received from the other device;

controlling light emission of a light-emitting unit in accordance with a timing at which a signal is received through wireless communication when the light emission period is equal to or greater than a predetermined value; and

controlling the light emission of the light-emitting unit in accordance with an internal timer when the light emission period is less than the predetermined value.
