Abstract

An information processing method is described that includes obtaining a first operation that is used to select a foreground image from a first picture; determining the foreground image in the first picture based on the first operation; obtaining status information of the foreground image; obtaining a second operation that is used to place the foreground image into a second picture; determining the second picture which serves as a background based on the second operation; obtaining status information of the second picture; determining a target size occupied by the foreground image in the second picture based on the status information of the foreground image and the second picture; scaling the foreground image into the target size; and displaying the foreground image in the second picture with the target size. An electronic device is also described.

First claim

1 . An information processing method comprising:
obtaining a first operation, the first operation being used to select a foreground image from a first picture; determining the foreground image in the first picture based on the first operation; obtaining status information of the foreground image; obtaining a second operation, the second operation being used to place the foreground image into a second picture; determining the second picture which serves as a background based on the second operation; obtaining status information of the second picture; determining a target size occupied by the foreground image in the second picture based on the status information of the foreground image and the status information of the second picture; scaling the foreground image into the target size; and displaying the foreground image in the second picture with the target size.

2 . The method of claim 1 , wherein the first operation and the second operation are actions having coherence; or, the first operation and the second operation are actions having a spacing of a first time period.

3 . The method of claim 1 , wherein
the status information comprises depth information of an object in a picture and a size occupied by the object in the picture; the obtaining status information of the foreground image comprises obtaining a first size occupied by the foreground image in the first picture and first depth information of the foreground image in the first picture; the obtaining status information of the second picture comprises obtaining second depth information of the second picture; the determining a target size occupied by the foreground image in the second picture based on the status information of the foreground image and the status information of the second picture comprises determining the target size occupied by the foreground image in the second picture based on the first size, the first depth information, and the second depth information.

4 . The method of claim 3 , wherein
the status information further comprises a focal length of an image acquiring unit for taking a picture; and the determining the target size occupied by the foreground image in the second picture based on the first size, the first depth information, and the second depth information comprises determining the target size occupied by the foreground image in the second picture based on the first size, the first depth information, the second depth information, a focal length of the image acquiring unit for taking the first picture, and a focal length of the image acquiring unit for taking the second picture.

5 . The method of claim 3 , wherein obtaining a first size occupied by the foreground image in the first picture comprises obtaining a total number of pixels included in the foreground image.

6 . The method of claim 4 , wherein the image acquiring unit comprises a first image acquiring sub-unit and a second image acquiring sub-unit, the first image acquiring sub-unit and the second image acquiring sub-unit are located at two sides of the electronic device, respectively, the first picture is taken by the first image acquiring sub-unit, and the second image is taken by the second image acquiring sub-unit.

7 . An electronic device comprising a first obtaining unit, a first determining unit, a second obtaining unit, a third obtaining unit, a second determining unit, a fourth obtaining unit, a third determining unit, a scaling unit, and a display unit, in which:
the first obtaining unit is configured to obtain a first operation, the first operation being used to select a foreground image from a first picture; the first determining unit is configured to determine the foreground image in the first picture based on the first operation; the second obtaining unit is configured to obtain status information of the foreground image; the third obtaining unit is configured to obtain a second operation, the second operation being used to place the foreground image into a second picture; the second determining unit is configured to determine the second picture which serves as a background based on the second operation; the fourth obtaining unit is configured to obtain status information of the second picture; the third determining unit configured to determine a target size occupied by the foreground image in the second picture based on the status information of the foreground image and the status information of the second picture; the scaling unit is configured to scale the foreground image into the target size; and the display unit is configured to display the foreground image in the second picture with the target size.

8 . The electronic device of claim 7 , wherein the first operation unit and the third operation unit are configured to obtain the first operation and the second operation having coherence or having a spacing of a first time period there between.

9 . The electronic device of claim 7 , wherein
the status information comprises depth information of an object in a picture and a size occupied by the object in the picture; the second obtaining unit comprises a first obtaining module and a second obtaining module, the first obtaining module is configured to obtain a first size occupied by the foreground image in the first picture and the second obtaining module is configured to obtain first depth information of the foreground image in the first picture; the fourth obtaining unit is configured to obtain second depth information of the second picture; and the third determining unit is configured to determine the target size occupied by the foreground image in the second picture based on the first size, the first depth information, and the second depth information.

10 . The electronic device of claim 9 , wherein
the status information further comprises a focal length of an image acquiring unit for taking a picture; and the third determining unit is configured to determine the target size occupied by the foreground image in the second picture based on the first size, the first depth information, the second depth information, a focal length of the image acquiring unit for taking the first picture, and a focal length of the image acquiring unit for taking the second picture.

11 . The electronic device of claim 9 , wherein the first obtaining module is configured to obtain a total number of pixels included in the foreground image.

12 . The electronic device of claim 10 , wherein the image acquiring unit comprises a first image acquiring sub-unit and a second image acquiring sub-unit, the first image acquiring sub-unit and the second image acquiring sub-unit are located at two sides of the electronic device, respectively, the first picture is taken by the first image acquiring sub-unit, and the second image is taken by the second image acquiring sub-unit.
