Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

In order to bring better product experience to users, the common network resources almost adopt the sRGB standard, and adopt the DCI-P3 color gamut standard in some terminal devices to display a wider color gamut for users, fig. 1 is a diagram showing a comparison example of an sRGB color gamut and a DCI-P3 color gamut according to an exemplary embodiment, as shown in fig. 1, where a hatched portion is all colors that can be captured by human eyes, and a dashed triangle area is a color distribution area that can be presented to users by some user devices through a display device, and on the basis of the sRGB color gamut, the color distribution area displayed by the user devices can be converted from the sRGB color gamut into the DCI-P3 color gamut by adjusting the configuration of the display device of the user devices and the configuration of the internal color management area. The color gamut richness is improved, so that a user can observe more colors through the display device of the user equipment, and better product experience is brought to the user.

However, in the related art, the user equipment satisfying the DCI-P3 color gamut cannot well realize accurate expression of the content. For the user equipment, when capturing an environmental image through the image capturing device of the user equipment, the environmental image displayed on the display device of the user equipment through the image capturing device is the DCI-P3 color gamut image information, but after the user operates the shutter to generate an environmental photo, the user equipment generates the sRGB color gamut photo information in the album of the user equipment based on a preset photo generation algorithm, so that the DCI-P3 color gamut image information is displayed when the image is acquired, but after photographing is completed, the sRGB color gamut image information is generated, so that the display effect of photographing preview and photo display has color difference, the problem of non-uniform display effect is caused, and the product experience of the user is affected.

In view of this, the present embodiment provides an image processing method, and fig. 2 is a flowchart of an image processing method according to an exemplary embodiment, and the processing method is used in a user equipment, as shown in fig. 2, and includes the following steps.

In step S101, an initial image is generated in response to an operation of image acquisition by the user device.

It should be noted that, the present embodiment is applied to a user device, where the user device supports a preset wide color gamut coverage, where the preset wide color gamut is, with respect to the sRGB color gamut standard, in a color gamut range that can be captured by a user through the naked eye, a color gamut range corresponding to the preset wide color gamut can fully cover a color gamut range corresponding to the sRGB color gamut, and the color gamut range corresponding to the preset wide color gamut is greater than the color gamut range corresponding to the sRGB color gamut, and as illustrated in fig. 1, the preset wide color gamut may be a DCI-P3 color gamut. When the user equipment takes a picture through the camera device, the environment image captured by the camera device can be previewed through the display device, and the environment image is displayed to the user in the display device, so that the user can collect the environment photo by referring to the environment image. When the environment image preview is performed, the user equipment displays the environment image under the DCI-P3 color gamut to the user through the display device based on the configuration of the DCI-P3 color gamut.

After the user determines the environmental image to be acquired through the display device, the user equipment performs image acquisition operation to generate a corresponding initial picture, and the initial picture can be generated in the user equipment by clicking a shutter operation.

In step S102, configuration description information of the initial image is determined, the configuration description information including a color gamut type, image tone scale information, and image transfer function information.

For example, in this embodiment, the initial image generated in the above step is identified, and configuration description information of the initial image is determined, where the configuration description information is used to describe the color gamut type, the image tone scale information, and the image transfer function information of the initial image. Wherein the gamut type is used to describe the image based on which gamut standard the initial image was generated; the image tone information is image tone information of each pixel point in the initial image under the color gamut type, and the image tone information can comprise white point information, tone conversion matrix information and the like of the initial image under the color gamut type; the image transfer function information may convert the initial image into a display image on the display device according to the image tone scale information.

It should be noted that, in this embodiment, although the image capturing and the image displaying of the user equipment support the preset wide color gamut, the initial image captured and generated by the image capturing device may include multiple types of color gamut types, for example, when the original camera APP (Application program) of the user equipment captures and photographs, the color gamut type corresponding to the generated initial image is the initial image of the preset wide color gamut; when photographing through some of the three-party cameras APP of the user equipment, an initial image of the sRGB color gamut type may be generated based on an image generation algorithm of the three-party cameras APP. Therefore, the color gamut type of the initial image needs to be identified.

In step S103, wide color gamut data information of the initial image in a preset wide color gamut data space is generated according to the color gamut type and the image gradation information.

It should be noted that, in this embodiment, by analyzing the color gamut type of the initial image, when the color gamut type is determined to be the preset wide color gamut, the image tone scale information is directly written into the preset wide color gamut data space for data conversion, and the image tone scale information is converted into the wide color gamut data information through the preset data conversion algorithm in the preset wide color gamut data space. When the color gamut type is determined not to be the preset wide color gamut, the color gamut range corresponding to the color gamut type can be compared with the color gamut range of the preset wide color gamut, a color gamut conversion algorithm between the color gamut type and the preset wide color gamut is determined through an experimental mode of biological simulation, the image tone scale information under the color gamut type is converted into the target image tone scale information under the preset wide color gamut according to the color gamut conversion algorithm, the target image tone scale information is written into a preset wide color gamut data space, and the target image tone scale information is converted into the wide color gamut data information through a preset data conversion algorithm in the preset wide color gamut data space. For example, the preset wide color gamut may be DCI-P3, and when the color gamut type of the initial image is determined to be DCI-P3, P3 information in the DCI-P3 data space may be generated according to the image tone information.

In step S104, target wide color gamut data information of the display device corresponding to the user equipment is generated according to the wide color gamut data information and the image transfer function information.

It should be noted that the wide color gamut data information determined by the calculation in the above steps is the wide color gamut value of each pixel point of the initial image under the preset wide color gamut, where the wide color gamut value corresponds to the color coordinates of each pixel point that can be captured by the naked human eye in fig. 1. For the user equipment, the color coordinates are required to be converted into signal data which can be displayed in corresponding colors by the display device by combining with a preset wide color gamut, so that the image in the corresponding colors is displayed at the corresponding positions of the display device. Therefore, in this embodiment, after the wide color gamut data information of the initial image in the preset wide color gamut data space is determined through the above steps, the wide color gamut data information is converted into the target wide color gamut data information corresponding to the display device through the image transfer function information. By way of example, the image transfer function information may be EOTF (Electro-optical-Optical Transfer Function, electro-optical conversion function) by which wide color gamut data information is converted into target wide color gamut data information for image display in a display device.

Optionally, in one embodiment, step S104 includes:

And performing color gamut conversion on the wide color gamut data information according to a color gamut conversion module of the user equipment so as to generate initial wide color gamut data information under a preset wide color gamut.

And converting the initial wide color gamut data information into target wide color gamut data information through a color gamut calibration module of the user equipment according to the image transfer function information.

For example, in this embodiment, a color gamut conversion module and a color gamut calibration module are configured in the user device, where the color gamut conversion module is configured to convert color gamut data, and the color gamut calibration module is configured to convert color gamut data corresponding to an image into color gamut data corresponding to a screen. After the wide color gamut data information corresponding to the image is generated through the steps, the color gamut conversion module performs color gamut data conversion on the wide color gamut data information, and initial wide color gamut data information under a preset wide color gamut is generated. And converting the initial wide color gamut data information into target wide color gamut data information through the image transfer function information by applying a color gamut calibration module.

In step S105, the adjusted initial image is displayed by the display device according to the target wide color gamut data information.

For example, in this embodiment, after the target wide color gamut data information is generated through the above steps, the target wide color gamut data information is transferred to the DDIC (DISPLAY DRIVER IC, display driver chip) of the user device, and the DDIC displays the initial image in the display device of the user device according to the target wide color gamut data information. Wherein the color gamut type corresponding to the initial image displayed in the display device at this time is a preset wide color gamut. Therefore, the display effects of the initial image in the camera shooting stage and the image display stage are unified, the richness of the image display colors in the user equipment is enhanced, and better use experience is brought to the user.

Alternatively, in another embodiment, the step S105 includes:

And transmitting the target wide color gamut data information to a display driving chip of the user equipment to generate a target display image.

In response to a selection operation of the initial image, a target display image is displayed in the display device.

In this embodiment, the target wide color gamut data information is sent to a display driver chip of the user device, and the display driver chip generates a target display image according to the target wide color gamut data information. And storing the target display image in a preset storage space, and displaying the target display image in a display device when a user clicks the user equipment to view the initial image.

In the above manner, in response to the image acquisition operation of the user equipment, an initial image is generated, configuration description information of the initial image is determined, and the configuration description information comprises the color gamut type and the image tone information

And image transfer function information, generating wide color gamut data information of the initial image in a preset 5 wide color gamut data space according to the color gamut type and the image tone scale information, generating target wide color gamut data information of a display device corresponding to the user equipment according to the wide color gamut data information and the image transfer function information, and displaying the adjusted initial image through the display device according to the target wide color gamut data information. Therefore, the effect display of globally supporting a wide color gamut from photographing to screen photo display is realized, the effect obtained immediately after the display is realized, the problem of non-uniform effect from photographing to display is solved, and better use experience is brought to users.
