Abstract

The present disclosure relates to a method and system for taking photos. According to another embodiment of the present invention, there is provided a system. The system includes an electronic device having a camera. The electronic device is configured to determine an object to be taken by the camera. Then the electronic device is configured to determine at least one shooting parameter for the object based on at least one previous photo related to the object. The electronic device is further configured to cause a setting of the camera to be adjusted based on the at least one shooting parameter. According to a further embodiment of the present invention, there is provided a computer program product. The computer program produce is tangibly stored on a non-transient machine-readable medium and include machine-executable instructions.

First claim

What is claimed is:

1. A method comprising:
determining, by an electronic device, an object to be taken by a camera of the electronic device;
determining, by the electronic device, at least one shooting parameter for the object based on at least one previous photo related to the object, wherein determining, by the electronic device, the at least one shooting parameter for the object comprises:
in response to the object including a plurality of persons, selecting, by the electronic device, at least one person from the plurality of persons as a target person, and
determining, by the electronic device, the at least one shooting parameter in association with the target person; and

causing, by the electronic device, a setting of the camera to be adjusted based on the at least one shooting parameter.

2. The method of claim 1 , wherein causing, by the electronic device, a setting of the camera to be adjusted comprises:
causing, by the electronic device, a pose of the camera relative to the object to be adjusted.

3. The method of claim 1 , wherein determining, by the electronic device, at least one shooting parameter for the object further comprises:
determining, by the electronic device, a previous angle of the object relative to the electronic device based on the at least one previous photo; and
wherein causing, by the electronic device, a setting of the camera to be adjusted comprises:
determining, by the electronic device, a current angle of the object relative to the electronic device; and
causing, by the electronic device, the setting of the camera to be adjusted based on a difference between the previous angle and the current angle.

4. The method of claim 3 , wherein at least one of the previous angle and the current angle is determined by:
in response to the object including a person, identifying, by the electronic device, a plurality of feature points of the person, the plurality of feature points including at least one of the following:
a first group consisting of a root of a nose and tops of ears of the person, and
a second group consisting of the root of the nose and a middle of a lip of the person; and

determining, by the electronic device, based on the plurality of feature points and a coordinate of the camera, at least one angle of the person relative to the electronic device.

5. The method of claim 1 , wherein the at least one previous photo related to the object comprises at least one of:
a photo including a first object, a similarity between the first object and the object being above a predetermined threshold, or
a photo including a second object recognized to be a predetermined object.

6. The method of claim 1 , wherein determining, by the electronic device, the at least one shooting parameter for the object further comprises:
grouping, by the electronic device, the at least one previous photo related to the object based on brightness levels of the at least one previous photo related to the object;
determining, by the electronic device, a plurality of shooting parameters associated with the respective brightness based on the grouping;
determining, by the electronic device, a current brightness level of an environment in which the object is located; and
determining, by the electronic device, from the plurality of shooting parameters, the shooting parameters associated with the brightness levels matching with the current brightness level.

7. The method of claim 1 , wherein causing, by the electronic device, a setting of the camera to be adjusted comprises:
causing, by the electronic device, a distance from the camera to the object to be adjusted.

8. A system, comprising an electronic device coupled to a computer-readable memory unit, the memory unit comprising instructions that when executed by the electronic device implement a method comprising:
determining an object to be taken by a camera of the electronic device;
determining at least one shooting parameter for the object based on at least one previous photo related to the object, wherein determining, by the electronic device, the at least one shooting parameter for the object comprises:
in response to the object including a plurality of persons, selecting, by the electronic device, at least one person from the plurality of persons as a target person, and
determining, by the electronic device, the at least one shooting parameter in association with the target person; and

causing a setting of the camera to be adjusted based on the at least one shooting parameter.

9. The system of claim 8 , wherein causing a setting of the camera to be adjusted comprises:
causing a pose of the camera relative to the object to be adjusted.

10. The system of claim 8 , wherein determining at least one shooting parameter for the object further comprises:
determining a previous angle of the object relative to the electronic device based on the at least one previous photo; and
wherein causing a setting of the camera to be adjusted comprises:
determining a current angle of the object relative to the electronic device; and
causing the setting of the camera to be adjusted based on a difference between the previous angle and the current angle.

11. The system of claim 10 , wherein at least one of the previous angle and the current angle is determined by:
in response to the object including a person, identifying a plurality of feature points of the person, the plurality of feature points including at least one of the following:
a first group consisting of a root of a nose and tops of ears of the person, and
a second group consisting of the root of the nose and a middle of a lip of the person; and

determining, based on the plurality of feature points and a coordinate of the camera, at least one angle of the person relative to the electronic device.

12. The system of claim 8 , wherein the at least one previous photo related to the object comprises at least one of:
a photo including a first object, a similarity between the first object and the object being above a predetermined threshold, or
a photo including a second object recognized to be a predetermined object.

13. The system of claim 8 , wherein determining the shooting parameter for the object comprises:
grouping the at least one previous photo related to the object based on brightness levels of the at least one previous photo related to the object;
determining a plurality of shooting parameters associated with the respective brightness based on the grouping;
determining a current brightness level of an environment in which the object is located; and
determining, from the plurality of shooting parameters, the shooting parameters associated with the brightness levels matching with the current brightness level.

14. A computer program product being tangibly stored on a non-transient machine-readable medium and comprising machine-executable instructions, the instructions, when executed on an electronic device having a camera, causing the electronic device to:
determine an object to be taken by the camera;
determine at least one shooting parameter for the object based on at least one previous photo related to the object, wherein the instructions to determine the at least one shooting parameter for the object comprise;
instructions to, in response to the object including a plurality of persons, select at least one person from the plurality of persons as a target person, and
instructions to determine the at least one shooting parameter in association with the target person; and

cause a setting of the camera to be adjusted based on the at least one shooting parameter.
