Photographing apparatus and operating method thereof

1. A photographing apparatus comprising a processor and a memory storing one or more commands that, when executed by the processor, cause the processor to perform operations, the operations comprising:

receiving a first communication signal and a second communication signal from a subject;

identifying photographing reference information from the communication signal, the photographing reference information comprising a state of motion of the subject;

identifying a first RSSI from the first communication signal and a second RSSI from the second communication signal;

determining a time period between a first moment that the first communication signal is received and a second moment that the second communication signal is received;

determining the state of motion based on the first RSSI, the second RSSI, and the time period; and

based on the state of motion, controlling a shutter speed to capture a photo that includes the subject.

2. The photographing apparatus of claim 1 , wherein the photographing reference information further comprises a distance between the photographing apparatus and the subject, wherein the distance is determined using a Received Signal Strength Indicator (RSSI) of the communication signal, and further comprising controlling a focus value based the distance determined using the RSSI to control a focus value to capture the photo.

3. The photographing apparatus of claim 1 , wherein determining the state of motion includes:

determining a moving speed of the subject based on the first RSSI, the second RSSI, and the time period.

4. The photographing apparatus of claim 3 , wherein the moving speed of the subject is proportional to a difference between a value of the first RSSI and a value of the second RSSI.

5. The photographing apparatus of claim 2 , wherein the operations further include:

processing advance photographing of the subject at an advance photographing time; obtaining a particular focus value that is used to process the advance photographing of the subject at the advance photographing time; and

generating photographing criterion information that includes the particular focus value.

6. The photographing apparatus of claim 5 , wherein the operations further include:

identifying, from the photographing criterion information, the particular focus value;

adjusting the particular focus value based on the distance of the photographing reference information; and

processing the photographing of the subject based on the adjusted focus value.

7. A method comprising:

receiving a first communication signal and a second communication signal from a subject;

identifying photographing reference information from the communication signal, the photographing reference information comprising a state of motion of the subject;

identifying a first RSSI from the first communication signal and a second RSSI from the second communication signal;

determining a time period between a first moment that the first communication signal is received and a second moment that the second communication signal is received;

determining the state of motion based on the first RSSI, the second RSSI, and the time period; and

based on the state of motion, controlling a shutter speed to capture a photo that includes the subject.

8. The method of claim 7 , wherein the photographing reference information further comprises a distance between the photographing apparatus and the subject, wherein the distance is determined using a Received Signal Strength Indicator (RSSI) of the communication signal, and further comprising controlling a focus value based the distance determined using the RSSI to control a focus value to capture the photo.

9. The method of claim 7 , wherein determining the state of motion includes:

determining a moving speed of the subject based on the first RSSI, the second RSSI, and the time period.

10. The method of claim 9 , wherein the moving speed of the subject is proportional to a difference between a value of the first RSSI and a value of the second RSSI.

11. The method of claim 8 , further comprising:

processing advance photographing of the subject at an advance photographing time; obtaining a particular focus value that is used to process the advance photographing of the subject at the advance photographing time; and

generating photographing criterion information that includes the particular focus value.

12. The method of claim 11 , further comprising:

identifying, from the photographing criterion information, the particular focus value;

adjusting the particular focus value based on the distance of the photographing reference information; and

processing the photographing of the subject based on the adjusted focus value.

13. A non-transitory computer-readable storage media encoded with instructions, when executed by a processor, cause the processor to:

receive a first communication signal and a second communication signal from a subject;

identify photographing reference information from the communication signal, the photographing reference information comprising a state of motion of the subject;

identify a first RSSI from the first communication signal and a second RSSI from the second communication signal;

determine a time period between a first moment that the first communication signal is received and a second moment that the second communication signal is received;

determine the state of motion based on the first RSSI, the second RSSI, and the time period; and

based on the state of motion control a shutter speed to capture a photo that includes the subject.

14. The computer-readable storage media of claim 13 , wherein the photographing reference information further comprises a distance between the photographing apparatus and the subject, wherein the distance is determined using a Received Signal Strength Indicator (RSSI) of the communication signal, and further comprising controlling a focus value based the distance determined using the RSSI to control a focus value to capture the photo.

15. The computer-readable storage media of claim 13 , wherein instructions for determining the state of motion causes the processor to:

determine a moving speed of the subject based on the first RSSI, the second RSSI, and the time period, and

wherein the moving speed of the subject is proportional to a difference between a value of the first RSSI and a value of the second RSSI.

16. The computer-readable storage media of claim 14 , further storing instructions that cause the processor to:

process advance photographing of the subject at an advance photographing time; obtaining a particular focus value that is used to process the advance photographing of the subject at the advance photographing time; and

generate photographing criterion information that includes the particular focus value.

17. The computer-readable storage media of claim 16 , further storing instructions that cause the processor to:

identify, from the photographing criterion information, the particular focus value;

adjust the particular focus value based on the distance of the photographing reference information; and

process the photographing of the subject based on the adjusted focus value.
