Transmitter, transmitting method, and receiving method
First Claim
1. An apparatus, comprising:
- a light source;
a first memory storing a visible light signal;
a receiver configured to receive another visible light signal, which rewrites over the visible light signal stored in the first memory, by a communication method that is different from a visible light communication, anda control circuit configured to(i) control a change in luminance of the light source in accordance with the visible light signal,(ii) determine whether the visible light signal is to be rewritten by the another visible light signal or not, based on a received password included in the communication method that is different from the visible light communication, the password being stored in a second memory in the apparatus, when the receiver receives the another visible light signal,(iii) rewrite the visible light signal by the another visible light signal when it is determined that the visible light signal is to be rewritten by the another visible light signal, and(iv) control the change in luminance of the light source to transmit another visible light signal.

Abstract
An apparatus is provided that includes a light source, a memory storing a visible light signal, a control circuit configured to control change in luminance of the light source in accordance with the visible light signal, and a receiver configured to receive another visible light signal, which rewrites over the visible light signal, by a communication method that is different from a visible light communication. The control circuit determines whether the visible light signal is rewritten by the another visible light signal or not when the receiver receives the another visible light signal, and the visible light signal is rewritten by the another visible light signal when the control circuit determines the visible light signal is rewritten by the another visible light signal. The control circuit controls the change in luminance of the light source to transmit the another visible light signal.

6. An apparatus, comprising:
-
a light source; a processor; and a first memory storing a visible light signal and storing thereon a computer program, which when executed by the processor, causes the processor to be configured to (i) receive another visible light signal, which rewrites over the visible light signal stored in the first memory, by a communication method that is different from a visible light communication, (ii) determine whether the visible light signal is rewritten by the another visible light signal or not, based on a password included in the communication method that is different from the visible light communication, the password being stored in a second memory in the apparatus, when the another visible light signal is received, (iii) rewrite the visible light signal by the another visible light signal when the visible light signal is determined to be rewritten by the another visible light signal, and (iv) control a change in luminance of the light source to transmit the another visible light signal.

7. A method, comprising:
-
storing a visible light signal in a first memory; controlling, by a control circuit, a change in luminance of a light source in accordance with the visible light signal, receiving, by a receiver, another visible light signal, that rewrites over the visible light signal stored in the first memory, by a communication process that is different from a visible light communication, determining, by the control circuit, whether the visible light signal is to be rewritten by the another visible light signal or not, based on a password included in the communication method that is different from the visible light communication, the password being stored in a second memory, when the receiver receives the another visible light signal, rewriting, by the control circuit, the visible light signal by the another visible light signal when it is determined that the visible light signal is to be rewritten by the another visible light signal, and controlling the change in luminance of the light source to transmit another visible light signal. - View Dependent Claims (8, 9, 10, 11)

12. A tangible computer-readable storage medium that stores therein a computer-executable computer program, which when executed by a computer, causes the computer to be configured to:
-
store a visible light signal in a first memory, receive another visible light signal, which rewrites over the visible light signal stored in the first memory, by a communication method that is different from a visible light communication, determine whether the visible light signal is rewritten by the another visible light signal or not, based on a received password included in the communication method that is different from the visible light communication, the password being stored in a second memory, when the another visible light signal is received, rewrite the visible light signal by the another visible light signal when the visible light signal is determined to be rewritten by the another visible light signal, and control a change in luminance of the light source to transmit the another visible light signal.
