## Abstract

A light emitting apparatus includes a light source, and a processor configured to perform control to cause the light source to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus, and configured to, when causing the light source to blink by repeating the blink pattern, change a time interval between the blink patterns.

## Claims

### Claim 1

A light emitting apparatus comprising:
a light source;
a processor configured to
perform control to cause the light source to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus and stored in a memory of the light emitting apparatus, and
when causing the light source to blink by repeating the blink pattern, change a time interval between a first occurrence of the blink pattern and a second occurrence of the blink pattern subsequent to the first occurrence of the blink pattern; and
an acceleration sensor, wherein
the processor is further configured to, when causing the light source to blink by repeating the blink pattern, increase and change the time interval between the first occurrence of the blink pattern and the second occurrence of the blink pattern when the acceleration sensor detects that the light emitting apparatus is stationary, and reduce and make the time interval between the blink patterns constant when the acceleration sensor detects that the light emitting apparatus is moving.

### Claim 2 (depends on 1)

The light emitting apparatus according to claim 1, wherein the processor is configured to randomly change the time interval between the first occurrence of the blink pattern and the second occurrence of the blink pattern.

### Claim 3 (depends on 2)

The light emitting apparatus according to claim 2, wherein the processor is configured to set the time interval to a time period that is n times a blink time period of the blink pattern and randomly change the n, the n being a positive integer.

### Claim 4 (depends on 1)

The light emitting apparatus according to claim 1, wherein the processor is configured to, when the acceleration sensor detects that the light emitting apparatus is stationary, make the time interval longer than when the acceleration sensor detects that the light emitting apparatus is moving.

### Claim 5

A non-transitory computer readable medium storing instructions, which when executed by a processor of a light emitting apparatus, performs the steps of:
performing control to cause a light source included in the light emitting apparatus to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus and stored in a memory of the light emitting apparatus;
when causing the light source to blink by repeating the blink pattern, changing a time interval between a first occurrence of the blink pattern and a second occurrence of the blink pattern subsequent to the first occurrence of the blink pattern; and
when causing the light source to blink by repeating the blink pattern, increase and change the time interval between the first occurrence of the blink pattern and the second occurrence of the blink pattern when an acceleration sensor of the light emitting apparatus detects that the light emitting apparatus is stationary, and reduce and make the time interval between the blink patterns constant when the acceleration sensor detects that the light emitting apparatus is moving.

### Claim 6

A light emitting apparatus comprising:
a light source;
an acceleration sensor;
means for performing control to cause the light source to blink in a blink pattern corresponding to output information including identification information unique to the light emitting apparatus and stored in a memory of the light emitting apparatus;
means for, when causing the light source to blink by repeating the blink pattern, changing a time interval between a first occurrence of the blink pattern and a second occurrence of the blink pattern subsequent to the first occurrence of the blink pattern; and
means for, when causing the light source to blink by repeating the blink pattern, increasing and changing the time interval between the first occurrence of the blink pattern and the second occurrence of the blink pattern when the acceleration sensor of the light emitting apparatus detects that the light emitting apparatus is stationary, and reducing and making the time interval between the blink patterns constant when the acceleration sensor detects that the light emitting apparatus is moving.
