Abstract

An image processing method includes determining a display mode; processing, according to an image processing manner corresponding to the display mode, original image data to obtain target image data; and transmitting the target image data to an image display terminal, so that the image display terminal performs image display according to a scanning display manner corresponding to the display mode, a resolution of the target image data is less than or equal to that of the original image data, and the target image data carries indication information of the display mode.

First claim

What we claim is:

1 . An image processing method, comprising:
determining a display mode; processing, according to an image processing manner corresponding to the display mode, original image data to obtain target image data, wherein a resolution of the target image data is less than or equal to that of the original image data, and the target image data carries indication information of the display mode; and transmitting the target image data to an image display terminal, to allow the image display terminal to perform image display according to a scanning display manner corresponding to the display mode.

2 . The image processing method according to claim 1 , wherein the display mode is one of the following modes: a normal display mode, a two-dimensional display mode, a three-dimensional display mode and a stereoscopic light field display mode.

3 . The image processing method according to claim 1 , wherein determining the display mode comprises at least one of the following steps:
determining, according to a type of a running application, a display mode matched with the type of the application; and determining, in response to a user operation, a display mode selected by the user operation.

4 . The image processing method according to claim 2 , wherein
before processing the original image data, the method further comprises: starting a single-person mode or a multi-person mode according to a quantity of persons who are watching at the same time at the image display terminal and eye gaze parameters of each person; and processing, according to the image processing manner corresponding to the display mode, the original image data to obtain the target image data comprises: processing the original image data according to the image processing manner in the single-person mode or the multi-person mode corresponding to the display mode to obtain the target image data.

5 . The image processing method according to claim 4 , wherein starting the single-person mode or the multi-person mode according to the quantity of persons who are watching at the same time at the image display terminal and eye gaze parameters of each person comprises:
in a case that the quantity of persons who are watching at the same time at the image display terminal is one, or the quantity of persons who are watching at the same time at the image display terminal is more than one and the eye gaze parameters of the plurality of persons indicate a same gaze area, starting the single-person mode; and in a case that the quantity of persons who are watching at the same time at the image display terminal is more than one and the eye gaze parameters of the plurality of persons indicate at least two gaze areas, starting the multi-person mode.

6 . The image processing method according to claim 4 , wherein the display mode is a normal display mode, and the resolution of the target image data obtained according to the image processing manner in the single-person mode or the multi-person mode corresponding to the normal display mode is the same as that of the original image data.

7 . The image processing method according to claim 4 , wherein the display mode is a two-dimensional display mode; and
processing the original image data according to the image processing manner in the single-person mode or the multi-person mode corresponding to the display mode to obtain the target image data comprises: dividing an original image corresponding to the original image data into at least one gaze area and a plurality of non-gaze areas according to the eye gaze parameters collected at the image display terminal, sampling the at least one gaze area using an original resolution to obtain at least one gaze image, and sampling the plurality of non-gaze areas using a compressed resolution to obtain a plurality of corresponding non-gaze images; and splicing the at least one gaze image and the plurality of non-gaze images to obtain the target image data.

8 . The image processing method according to claim 7 , wherein processing the original image data according to the image processing manner in the multi-person mode corresponding to the display mode to obtain the target image data further comprises:
segmenting the at least one gaze image to form a plurality of rectangular gaze sub-images; and rearranging the plurality of gaze sub-images and the plurality of non-gaze images to subsequently obtain the target image data.

9 . The image processing method according to claim 4 , wherein the display mode is a three-dimensional display mode, and the original image data comprises a left eye image and a right eye image; and
processing the original image data according to the image processing manner in the single-person mode or the multi-person mode corresponding to the display mode to obtain the target image data comprises: dividing, according to the eye gaze parameters collected at the image display terminal, the left eye image into at least one first gaze area and a plurality of first non-gaze areas, dividing the right eye image into at least one second gaze area and a plurality of second non-gaze areas, sampling the at least one first gaze area and the at least one second gaze area using an original resolution to obtain at least one first gaze image and at least one second gaze image, and sampling the plurality of first non-gaze areas and the plurality of second non-gaze areas using a compressed resolution to obtain a plurality of first non-gaze images and a plurality of second non-gaze images; and splicing the at least one first gaze image, the at least one second gaze image, the plurality of first non-gaze images and the plurality of second non-gaze images to obtain the target image data.

10 . The image processing method according to claim 4 , wherein the display mode is a stereoscopic light field display mode, and the original image data comprises a plurality of unit images; and
processing the original image data according to the image processing manner in the single-person mode or the multi-person mode corresponding to the display mode to obtain the target image data comprises: for any unit image, dividing the unit image into at least one gaze area and a plurality of non-gaze areas according to the eye gaze parameters collected at the image display terminal, sampling the at least one gaze area using an original resolution to obtain at least one gaze image, and sampling the plurality of non-gaze areas using a compressed resolution to obtain a plurality of non-gaze images; and splicing a plurality of gaze images and the plurality of non-gaze images obtained according to the plurality of unit images to obtain the target image data, wherein the target image data comprises a plurality of frames of image data.

11 . An image display method, comprising:
receiving target image data; determining a display mode by analyzing the target image data; and performing image display on a display at an image display terminal according to a scanning display manner corresponding to the display mode.

12 . The image display method according to claim 11 , wherein the display mode is one of the following modes: a normal display mode, a two-dimensional display mode, a three-dimensional display mode, and a stereoscopic light field display mode.

13 . The image display method according to claim 12 , wherein performing image display on the display at an image display terminal according to the scanning display manner corresponding to the display mode comprises:
in a case that the display mode is a normal display mode, displaying an image to be displayed on the display according to a relationship between a resolution o
