## Abstract

A reception device includes: an image sensor that captures an image, and a reception unit configured to sample a plurality of pixels included in each of N (N being an integer greater than or equal to two) regions included in an imaging surface of the image sensor to receive, in parallel, N mutually different optical signals transmitted from a plurality of light sources.

## Claims

### Claim 1

A receiving apparatus, comprising:
one or more image sensors that, in operation, obtain image data, a first received signal, and a second received signal different from the first received signal; and
a processor that, in operation, performs:
detecting a first object and a second object which appear in the image data by performing image processing on the image data, the first object transmitting the first received signal, and the second object transmitting the second received signal;
demodulating the first received signal to obtain first demodulated data;
demodulating the second received signal to obtain second demodulated data;
storing the first demodulated data in a memory, the first demodulated data being associated with the detected first object, and the first demodulated data not being associated with the detected second object; and
storing the second demodulated data in the memory, the second demodulated data being associated with the detected second object, and the second demodulated data not being associated with the detected first object.

### Claim 2 (depends on 1)

The receiving apparatus according to claim 1, wherein
the first demodulated data includes first connection information to connect to the first object by wireless communication, and
the second demodulated data includes second connection information to connect to the second object by the wireless communication.

### Claim 3 (depends on 1)

The receiving apparatus according to claim 1, wherein
the association between the detected first object and the first demodulated data is determined based on a position of the detected first object in the image data, and
the association between the detected second object and the second demodulated data is determined based on a position of the detected second object in the image data.

### Claim 4

A receiving method performed by a receiving apparatus comprising one or more image sensor, the receiving method comprising:
obtaining image data, a first received signal, and a second received signal different from the first received signal by the one or more image sensors;
detecting a first object and a second object which appear in the image data by performing image processing on the image data, the first object transmitting the first received signal, and the second object transmitting the second received signal;
demodulating the first received signal to obtain first demodulated data;
demodulating the second received signal to obtain second demodulated data
storing the first demodulated data in a memory, the first demodulated data being associated with the detected first object, and the first demodulated data not being associated with the detected second object, and
storing the second demodulated data in the memory, the second demodulated data being associated with the detected second object, and the second demodulated data not being associated with the detected first object.

### Claim 5 (depends on 4)

The receiving method according to claim 4, wherein
the first demodulated data includes first connection information to connect to the first object by wireless communication, and
the second demodulated data includes second connection information to connect to the second object by the wireless communication.

### Claim 6 (depends on 4)

The receiving method according to claim 4, wherein
the association between the detected first object and the first demodulated data is determined based on a position of the detected first object in the image data, and
the association between the detected second object and the second demodulated data is determined based on a position of the detected second object in the image data.
