## Abstract

A communication method for obtaining information from a subject includes obtaining image information of the subject in an image information-taking mode, obtaining visible light data of the subject in a visible light communication mode, and setting a shutter speed and an international organization for standardization (ISO) speed rating or a gain value for the visible light communication mode. The visible light communication mode is a different mode from the image information-taking mode. Also, in the setting, the shutter speed for the visible light communication mode is set to be faster than a shutter speed for the image information-taking mode, and the ISO speed rating or the gain value for the visible light communication mode is set to be greater than an ISO speed rating or a gain value for the image information-taking mode.

## Claims

### Claim 1

A communication method for obtaining information from a subject, comprising:
obtaining image information of the subject in an image information-taking mode;
obtaining visible light data of the subject in a visible light communication mode, the visible light communication mode being a different mode from the image information-taking mode; and
setting a shutter speed and an international organization for standardization (ISO) speed rating or a gain value for the visible light communication mode,
wherein in the setting, the shutter speed for the visible light communication mode is set to be faster than a shutter speed for the image information-taking mode, and the ISO speed rating or the gain value for the visible light communication mode is set to be greater than an ISO speed rating or a gain value for the image information-taking mode.

### Claim 2 (depends on 1)

The communication method according to claim 1, further comprising:
selecting the image information-taking mode,
wherein, when the image-taking mode is selected, the obtaining of the image information of the subject is performed.

### Claim 3 (depends on 1)

The communication method according to claim 1, wherein the image information-taking mode and the visible light communication mode are switchable with one another, and
when the image-taking mode is selected, the obtaining of the image information of the subject is performed, and when the visible light communication mode is selected, the obtaining of the visible light data of the subject is performed.

### Claim 4

A communication apparatus for obtaining information from a subject, comprising:
a processor; and
a memory storing a computer program, wherein the computer program, when executed by the processor, causes the processor to perform operations comprising:
obtaining image information of the subject in an image information-taking mode;
obtaining visible light data of the subject in a visible light communication mode, the visible light communication mode being a different mode from the image information-taking mode; and
setting a shutter speed and an international organization for standardization (ISO) speed rating or a gain value for the visible light communication mode,
wherein in the setting, the shutter speed for the visible light communication mode is set to be faster than a shutter speed for the image information-taking mode, and the ISO speed rating or the gain value for the visible light communication mode is set to be greater than an ISO speed rating or a gain value for the image information-taking mode.

### Claim 5

A non-transitory computer-readable recording medium that stores a computer program, when executed by a processor, causes a computer to execute a communication method for obtaining information from a subject, the communication method including:
obtaining image information of the subject in an image information-taking mode;
obtaining visible light data of the subject in a visible light communication mode, the visible light communication mode being a different mode from the image information-taking mode; and
setting a shutter speed and an international organization for standardization (ISO) speed rating or a gain value for the visible light communication mode,
wherein in the setting, the shutter speed for the visible light communication mode is set to be faster than a shutter speed for the image information-taking mode, and the ISO speed rating or the gain value for the visible light communication mode is set to be greater than an ISO speed rating or a gain value for the image information-taking mode.

### Claim 6 (depends on 1)

The communication method according to claim 1, further comprising:
selecting the visible light communication mode,
wherein when the visible light communication mode is selected, the obtaining of the visible light data of the subject is performed.
