Abstract

The present disclosure provides an image acquisition and processing method. The method includes acquiring an invoking event being configured to invoke an image acquisition device located under a display screen, an acquisition window of the image acquisition device corresponding to a first area of the display screen; activating the image acquisition device based on the invoking event; determining a display state of the first area; acquiring an image by using the image acquisition device based on the display state of the first area; and displaying the acquired image.

Claims

1. An image acquisition and processing method, comprising:

acquiring an invoking event configured to invoke an image acquisition device located under a display screen, an acquisition window of the image acquisition device corresponding to a first area of the display screen;

activating the image acquisition device based on the invoking event;

determining a display state of the first area;

acquiring an image by using the image acquisition device based on the display state of the first area; and

displaying the acquired image.

2. The method of claim 1, wherein acquiring the image by using the image acquisition device based on the display state of the first area includes one or more of the following operations:

acquiring the image directly through the image acquisition device in response to the display state of the first area being in a transparent state;

switching the display state of the first area to be in the transparent state and acquiring the image through the image acquisition device in response to the display state of the first area being in a non-transparent state; and

acquiring display information of the first area and acquiring the image through the image acquisition device in response to the display state of the first area being in the non-transparent state; and

processing the acquired image based on the display information, wherein the display information of the first area is used to present display content of the first area.

3. The method of claim 2, further including:

maintaining the transparent state of the first area until the image acquisition device is in a low power consumption state in response to the display state of the first area being in the transparent state; and

switching the display state of the first area to the non-transparent state and displaying based on the content to be display in response to the image acquisition device being in the low power consumption state.

4. The method of claim 2, further including:

displaying an interactive interface, the interactive interface includes a prompt area for prompting the image acquisition device being in an operating state, wherein the prompt area corresponds to an outer edge of the first area in response to the interactive interface being displayed on the display screen.

5. The method of claim 2, further comprising,

displaying the interactive interface, the visual effect of the presented by the interactive interface being that the first area on the interactive interface is a hole in response to the display state of the first area being in the transparent state.

6. The method of claim 4, wherein the interactive interface includes an output area for displaying the acquired image in real time, the output area including any one of the following format:

the output area does not include the prompt area;

or

the output area does not include the area corresponding to the first area of the display screen;

or

the output area includes the prompt area;

or,

the output area includes the area corresponding to the first area of the display screen.

7. The method of claim 2, further includes:

updating the display content of the first area of the display screen based on image information of a first part of the acquired image.

8. The method of claim 6, wherein:

the display information is a color value of each pixel in the first area, and processing the acquired image based on the display information includes;

determining correction parameters based on the color value of each pixel; and

processing the acquired image based on the correction parameters.

9. An image acquisition method, comprising:

acquiring display information of display content in a first area of a display screen, the first area corresponds to an acquisition window of an image acquisition device being disposed under the display screen;

acquiring an image through the image acquisition device;

processing the acquired image based on the display information; and

displaying a processed acquired image.

10. An image acquisition and processing apparatus, comprising:

an invoking module configured to obtain an invoking event for invoking an image acquisition device located under a display screen, an acquisition window of the image acquisition device corresponds to a first area of the display screen;

an activation module configured to activate the image acquisition device based on the invoking event;

a state determination module configured to determine a display state of the first area;

an acquisition module configured to acquire an image by using the image acquisition device based on the display state of the first area; and

an output module configured to output the acquired image.

11. The apparatus of claim 10, wherein the acquisition module is further configured to perform one or more of the following operations:

acquiring the image directly through the image acquisition device in response to the display state of the first area being in a transparent state;

switching the display state of the first area to be in the transparent state and acquiring the image through the image acquisition device in response to the display state of the first area being in a non-transparent state; and

acquiring display information of the first area and acquiring the image through the image acquisition device in response to the display state of the first area being in the non-transparent state; and

processing the acquired image based on the display information, wherein the display information of the first area is used to present display content of the first area.

12. The apparatus of claim 11, wherein the acquisition module is further configured to perform one or more of the following operations:

maintaining the transparent state of the first area until the image acquisition device is in a low power consumption state in response to the display state of the first area being in the transparent state; and

switching the display state of the first area to the non-transparent state and displaying based on the content to be display in response to the image acquisition device being in the low power consumption state.

13. The apparatus of claim 12, wherein the acquisition module is further configured to perform:

displaying an interactive interface, the interactive interface includes a prompt area for prompting the image acquisition device being in an operating state, wherein the prompt area corresponds to an outer edge of the first area in response to the interactive interface being displayed on the display screen.

14. The apparatus of claim 11, wherein the acquisition module is further configured to perform:

displaying the interactive interface, the visual effect of the presented by the interactive interface being that the first area on the interactive interface is a hole in response to the display state of the first area being in the transparent state.

15. The apparatus of claim 14, wherein the interactive interface includes an output area for displaying the acquired image in real time, the output area including any one of the following format:

the output area does not include the prompt area;

or

the output area does not include the area corresponding to the first area of the display screen;

or

the output area includes the prompt area;

or,

the output area includes the area corresponding to the first area of the display screen.

16. The apparatus of claim 11, wherein the acquisition module is further configured to perform:

updating the display content of the first area of the display screen based on image information of a first part of the acquired image.

17. The apparatus of claim 16, wherein:

the display information is a color value of each pixel in the first area, and processing the acquired image based on the display information includes;

determining correction parameters based on the color value of each pixel; and

processing the acquired image based on the correction parameters.
