Method of controlling operation of air conditioner by analyzing user's behavior pattern and air conditioner

1. An air conditioner, which analyzes a user's behavior patterns and controls operations, comprising:

an air blower configured to discharge air; and

a camera configured to acquire images of a space in which an indoor unit of the air conditioner is disposed,

wherein the air conditioner extracts features from the image acquired by the camera, generates image descriptions, and controls the air conditioner using parameters generated in response to the image descriptions,

wherein each image description includes a sentence, and the sentence includes a subject, a predicate, an object, and a prepositional phrase for position of a person,

wherein the image descriptions include information or words concerning actions of the person in the image and active or static features of actions of the person,

wherein the air conditioner controls air currents and temperatures on the basis of classification of the subject and the predicate, and, if the predicate is active, then the air conditioner increases the air currents or decreases the temperature,

wherein the air conditioner stores image descriptions and locations of objects that make no movement after repeatedly confirming the image descriptions, and

wherein the air conditioner confirms a location of the person by reflecting locations of the stored objects.

2. The air conditioner of claim 1 , wherein the air conditioner extracts features from the image, generates feature vectors, and generates the image descriptions including words using the feature vectors.

3. The air conditioner of claim 1 , wherein the control unit controls any one or more of speeds, amounts, directions, or temperatures of air discharged by the air conditioner, or operation modes of the air conditioner, using the image descriptions.

4. The air conditioner of claim 1 , wherein the image description comprises attribute information on an identified person in the image or words concerning actions of the identified person in the image or words describing the human.

5. The air conditioner of claim 1 , wherein the image description includes words describing clothes worn by an identified person in the image.

6. The air conditioner of claim 1 , wherein the image description includes words corresponding to a location of an identified person in the image.

7. The air conditioner of claim 1 , wherein the control unit places higher priority on an image description of a person at the center of the image or a person near the air conditioner in the image.

8. The air conditioner of claim 1 , wherein the control unit generates an image description of a difference between a first image acquired at a first point in time and a second image acquired at a second point in time after the first point in time, by comparing the first image and the second image.

9. A method of analyzing a user's behavior patterns and controlling operations of an air conditioner, comprising:

acquiring images of a space, in which an indoor unit of the air conditioner is disposed, by a camera of the air conditioner;

extracting features from the images, acquired by the camera, by a control unit of the air conditioner;

generating image descriptions describing the images on the basis of the extracted features by the control unit; and

controlling the air conditioner using parameters generated in response to the image descriptions by the control unit,

wherein each image description includes a sentence, and the sentence includes a subject, a predicate, an object, and a prepositional phrase for position of a person,

wherein the image descriptions include information or words concerning actions of the person in the image and active or static features of actions of the person,

wherein the air conditioner controls air currents and temperatures on the basis of classification of the subject and the predicate, and, if the predicate is active, then the air conditioner increases the air currents or decreases the temperature,

wherein the air conditioner stores image descriptions and locations of objects that make no movement after repeatedly confirming the image descriptions, and

wherein the air conditioner confirms a location of the person by reflecting locations of the stored objects.

10. The method of claim 9 , comprising:

receiving the images, extracting features and generating feature vectors by an encoder of the control unit; and

receiving the feature vectors and generating the image descriptions including words by a decoder of the control unit.

11. The method of claim 9 , further comprising:

controlling any one or more of speeds, amounts, directions, or temperatures of air discharged by the air conditioner, or operation modes of the air conditioner, using the image descriptions, by the control unit.

12. The method of claim 9 , wherein the image description includes words corresponding to a location of an identified person in the image.

13. The method of claim 9 , wherein the method further comprises placing higher priority on an image description of a person at the center of the image or a person near the air conditioner in the image by the control unit.

14. The method of claim 9 , wherein the method further comprises generating an image description of a difference between a first image acquired at a first point in time and a second image acquired at a second point in time after the first point in time by comparing the first image and the second image by the control unit.
