DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art are within the scope of protection of the present application.

[0014] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that the terms used in this way can be interchanged, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", and the like are generally of a kind and are not limited in number, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship.

[0015] The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The terms related to the embodiments of the present application are explained below.

[0016] Color space, also known as color space or color space, is a color space that is described in a generally acceptable manner under certain standards. Commonly used color spaces include red-green-blue (RGB) color space, hue-saturation-value (HSV) color space, etc.

[0017] Color space conversion type is the conversion type used to convert one color space to another color space, for example, BT601_YUV2RGB, BT709_YUV2RGB, BT2020_YUV2RGB, BT709_RGB2YUV, etc.

[0018] File header refers to specific format information at the beginning of a file, which is used to describe file type, version, metadata, or copyright declaration, etc.

[0019] With the popularity of dynamic images, the problem of color consistency has also been exposed, mainly the problem of inconsistency between the cover of the dynamic image and the video color. The cover is usually a P3 color gamut photo, while the video is usually SRGB color gamut, and the color gamut of the two is different, which leads to the inconsistency of the color of the cover and the video. When displaying the dynamic image, the picture will appear color jump when playing from the static picture to the video. In order to prevent the picture from appearing color jump when playing from the static picture to the video when displaying the dynamic image, color management needs to be performed on the dynamic image.

[0020] In the related art, when color management is performed on the dynamic image, the dynamic image is calibrated to P3 color gamut. When the dynamic image is captured by using the camera of the electronic device, the original (RAW) image data collected by the image sensor is converted into RGB image data under the P3 color gamut, and then the RGB image data is converted into YUV image data by using the color space conversion formula corresponding to the pre-set RGB2YUV color space conversion type, and the YUV image data is encoded to obtain a dynamic image file. In order to make the dynamic image display the effect of P3 color gamut, it is necessary to write P3 color space parameters in the file header of the dynamic image file; wherein the P3 color space parameters are: DISPLAY_P3=STANDARD_DCI_P3|TRANSFER_SRGB|RANGE_FULL.

[0021] Among them, the STANDARD in the color space parameter is defined according to the CIE 1931 x and y definition in ISO 11664-1, which defines the chromaticity coordinates of the image source, including the vertex and white point coordinates. There are usually STANDARD_BT601, STANDARD_BT709, STANDARD_DCI_P3, STANDARD_BT2020, etc.; the TRANSFER in the color space parameter represents the transmission curve, also known as the gamma curve, such as TRANSFER_SRGB, TRANSFER_GAMMA2_2, etc.; the RANGE in the color space parameter defines the gray scale value range corresponding to the image source pixel point, and there are usually RANGE_FULL and RANGE_LIMIT, etc.

[0022] When displaying the dynamic image, the dynamic image file is decoded to obtain YUV image data, and a graphics processing unit (GPU) or a display processing unit (DPU) determines a color space conversion formula corresponding to a YUV2RGB color space conversion type according to the STANDARD in the color space parameter. However, there is no YUV2RGB color space conversion formula corresponding to STANDARD_DCI_P3, so when converting YUV image data to RGB image data, only one YUV2RGB can be selected from three YUV2RGB standard types "BT601_YUV2RGB, BT709_YUV2RGB, and BT2020_YUV2RGB" to convert the YUV image data, so as to prevent color jump from static image playing to video when displaying the dynamic image. However, if the selected YUV2RGB type does not correspond to the RGB2YUV type used when converting RGB image data to YUV image data, the color of the displayed dynamic image will not be consistent with the color of the dynamic image collected by the image sensor. For example, the RGB2YUV type used when converting RGB image data to YUV image data is BT601_RGB2YUV, and the YUV2RGB type used when converting YUV image data to RGB image data is BT709_YUV2RGB.

[0023] It should be noted that BT601_RGB2YUV corresponds to BT601_YUV2RGB, BT709_RGB2YUV corresponds to BT709_YUV2RGB, and BT2020_RGB2YUV corresponds to BT2020_YUV2RGB.

[0024] To solve the problem that the color of the displayed dynamic image is inconsistent with the color of the dynamic image collected by the image sensor, the embodiments of the present application provide an image processing method, device, equipment and medium.

[0025] The image processing method, device, equipment and medium provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0026] It should be noted that the image processing method provided by the embodiments of the present application can be executed by a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted electronic device, or the like. In some embodiments of the present application, the image processing method is executed by an electronic device as an execution subject, and the image processing method provided by the embodiments of the present application is described.

[0027] Figure 1 is a flowchart of the image processing method provided by some embodiments of the present application. The image processing method comprises: Step 101: writing first information in a file header of a dynamic image file; wherein the dynamic image file is a file obtained by performing color space conversion and encoding on first RGB image data of a dynamic image in an RGB color space using a first color space conversion type, and the first information includes second color space conversion type information used for indicating a second color space conversion type.

[0028] In some embodiments of the present application, when a dynamic image is captured by using a camera of an electronic device, a RAW image data collected by an image sensor is converted into RGB image data in a P3 color gamut, and then the RGB image data is converted into YUV image data by using a color space conversion formula corresponding to the first color space conversion type, and the YUV image data is encoded to obtain a dynamic image file. After obtaining the dynamic image file, second color space conversion type information used for indicating the second color space conversion type is written in a file header of the dynamic image file.

[0029] In some embodiments of the present application, the second color space conversion type in the embodiments of the present application is the color space conversion type corresponding to the first color space conversion type.

[0030] Exemplarily, the first color space conversion type is BT601_YUV2RGB, and the second color space conversion type is BT601_YUV2RGB; the first color space conversion type is BT709_YUV2RGB, and the second color space conversion type is BT709_YUV2RGB; the first color space conversion type is BT2020_YUV2RGB, and the second color space conversion type is BT2020_YUV2RGB.

[0031] In some embodiments of the present application, in the case that a color gamut corresponding to the first color space conversion type is smaller than a source color gamut of the dynamic image, the first information includes P3 color space parameter information and the second color space conversion type information; wherein the source color gamut of the dynamic image is a P3 color gamut.

[0032] In some embodiments of the present application, the first color space conversion type is BT601_RGB2YUV, and the second color space conversion type is BT601_YUV2RGB; or, the first color space conversion type is BT709_RGB2YUV, and the second color space conversion type is BT709_YUV2RGB.

[0033] Exemplarily, when the first color space conversion type is BT601_RGB2YUV, the color gamut corresponding to the first color space conversion type is BT601 color gamut, the BT601 color gamut is smaller than the P3 color gamut, at this time, the P3 color space parameter information and the color space conversion type information corresponding to BT601_YUV2RGB are written in the file header of the dynamic image file.

[0034] Exemplarily, when the first color space conversion type is BT709_RGB2YUV, the color gamut corresponding to the first color space conversion type is BT709 color gamut, the BT709 color gamut is smaller than the P3 color gamut, at this time, the P3 color space parameter information and the color space conversion type information corresponding to BT709_YUV2RGB are written in the file header of the dynamic image file.

[0035] The P3 color space parameter information can be: DISPLAY_P3 = STANDARD_DCI_P3 | TRANSFER_SRGB | RANGE_FULL.

[0036] In some embodiments of the present application, in the case that the color gamut corresponding to the first color space conversion type is greater than the source color gamut of the dynamic image, the first information includes the second color space conversion type information and the P3 color gamut parameter; the second color space conversion type information is the color space parameter corresponding to the second color space conversion type, and the source color gamut of the dynamic image is the P3 color gamut.

[0037] In some embodiments of the present application, the first color space conversion type is BT2020_RGB2YUV, and the second color space conversion type is BT2020_YUV2RGB.

[0038] Exemplarily, when the first color space conversion type is BT2020_RGB2YUV, the color gamut corresponding to the first color space conversion type is BT2020 color gamut, the BT2020 color gamut is greater than the P3 color gamut, at this time, the BT2020 color space parameter information and the P3 color gamut parameter are written in the file header of the dynamic image file.

[0039] The BT2020 color space parameter information can be: DISPLAY_BT2020 = STANDARD_BT2020 | TRANSFER_SRGB | RANGE_FULL.

[0040] In some embodiments of the present application, when the first color space conversion type is BT2020_RGB2YUV, before step 101, the image processing method provided by the embodiments of the present application can further include: converting the RGB image data in the P3 gamut from the P3 gamut to the BT2020 gamut to obtain the first RGB image data, before the first RGB image data is color space converted by using the first color space conversion type.

[0041] In some embodiments of the present application, the image processing method provided by the embodiments of the present application can further include: decoding the dynamic image file to obtain YUV image data of the dynamic image in the YUV color space and second color space conversion type information; performing color space conversion on the YUV image data according to the second color space conversion type indicated by the second color space conversion type information to obtain the first RGB image data; and displaying the dynamic image according to the first RGB image data.

[0042] In some embodiments of the present application, the YUV image data of the dynamic image in the YUV color space and the second color space conversion type information can be obtained by decoding the dynamic image file. The specific process of decoding the dynamic image file can refer to the description in the related art, which will not be described here in detail by the embodiments of the present application.

[0043] When the file header of the dynamic image file is written with the P3 color space parameter information and the second color space conversion type information, for example, the file header of the dynamic image file is written with DISPLAY_P3=STANDARD_DCI_P3|TRANSFER_SRGB|RANGE_FULL and BT601_YUV2RGB, the second color space conversion type can be obtained as BT601_YUV2RGB by analyzing the BT601_YUV2RGB when the dynamic image file is parsed; for another example, the file header of the dynamic image file is written with DISPLAY_P3=STANDARD_DCI_P3|TRANSFER_SRGB|RANGE_FULL and BT709_YUV2RGB, the second color space conversion type can be obtained as BT709_YUV2RGB by analyzing the BT709_YUV2RGB when the dynamic image file is parsed.

[0044] When the file header of the dynamic image file is written with the color space parameter and the P3 gamut parameter corresponding to the second color space conversion type, for example, the file header of the dynamic image file is written with DISPLAY_BT2020=STANDARD_BT2020|TRANSFER_SRGB|RANGE_FULL and the P3 gamut parameter, when the dynamic image file is parsed, the STANDARD_BT2020 can be obtained through DISPLAY_BT2020=STANDARD_BT2020|TRANSFER_SRGB|RANGE_FULL, and then the second color space conversion type is determined to be BT2020_YUV2RGB according to the STANDARD_BT2020.

[0045] When the dynamic image file is decoded to obtain the YUV image data of the dynamic image in the YUV color space and the second color space conversion type information, the YUV image data is color space converted according to the second color space conversion type indicated by the second color space conversion type information, to obtain the first RGB image data.

[0046] Exemplarily, assuming that the second color space conversion type indicated by the second color space conversion type information is BT601_YUV2RGB, the YUV image data is color space converted by using the color space conversion formula corresponding to BT601_YUV2RGB, to obtain the RGB image data.

[0047] Exemplarily, assuming that the second color space conversion type indicated by the second color space conversion type information is BT2020_YUV2RGB, the YUV image data is color space converted by using the color space conversion formula corresponding to BT2020_YUV2RGB, to obtain the RGB image data.

[0048] In some possible implementations of the present application, the YUV image data is color space converted according to the second color space conversion type indicated by the second color space conversion type information, to obtain the first RGB image data can include: in the case that the implementation type of the application for displaying the dynamic image is TextureView or GLSurfaceView, calling a graphic processing unit (GPU) to color space convert the YUV image data according to the second color space conversion type, to obtain the first RGB image data; in the case that the implementation type of the application for displaying the dynamic image is SurfaceView, calling a display processing unit (DPU) to color space convert the YUV image data according to the second color space conversion type, to obtain the first RGB image data.

[0049] When the implementation type of the application displaying the dynamic image is SurfaceView, the YUV image data is sent to the DPU image composition unit, the DPU image composition unit performs color space conversion on the YUV image data by using the second color space conversion type to obtain RGB image data; when the implementation type of the application displaying the dynamic image is TextureView or GLSurfaceView, the YUV image data is sent to the GPU, and the GPU performs color space conversion on the YUV image data by using the second color space conversion type to obtain RGB image data.

[0050] In some embodiments of the present application, the implementation type of the application includes TextureView, GLSurfaceView and SurfaceView; wherein TextureView, GLSurfaceView and SurfaceView are rendering view classes; TextureView combines the high-efficiency rendering capability of SurfaceView and the flexibility of the view (View) system, supports complete View transformation (such as rotation, scaling, transparency, etc.), and is suitable for multimedia rendering scenarios that require dynamic effects and view transformation; GLSurfaceView is a view class optimized for OpenGL ES rendering, which inherits from SurfaceView, simplifies the initialization and rendering process of OpenGL ES, and has built-in embedded system graphics library (Embedded System Graphics Library, EGL) context management and rendering threads, and is suitable for developing two-dimensional or three-dimensional graphics applications, games, filter processing and other high-performance graphics scenarios; SurfaceView is used for efficiently drawing graphics or video in an independent thread, and is suitable for high-performance rendering scenarios such as video playback, games, camera preview, etc.

[0051] In some possible implementations of the present application, after obtaining the first RGB image data, the first RGB image data is sent to the layer composition module in the DPU image composition unit to be composed with other layers into a P3 gamut RGB image displayed on the screen.

[0052] The screen can only display RGB images, and its input is obtained by layer composition by the layer composition module in the DPU image composition unit. The layer is the input of the layer composition module, and the DPU composes multiple layers into a complete RGB image according to a certain order, and the number of layers varies with the change of the displayed scene. There can be multiple applications in a display screen, such as a video playback application, a status bar application, etc.; one application corresponds to at least one layer, and some applications have multiple layers, such as a video layer, a UI control layer, etc.

[0053] In the embodiments of the present application, after the first color space conversion type is used to perform color space conversion and encoding on the first RGB image data of the dynamic image in the RGB color space, the second color space conversion type information is written into the file header of the dynamic image file to indicate the second color space conversion type. When the dynamic image file is decoded, the second color space conversion type can be obtained, and the YUV image data obtained by decoding the dynamic image file using the second color space conversion type is converted in color space. The color of the displayed dynamic image is consistent with the color of the dynamic image collected by the image sensor, and the color of the dynamic image can be truly restored.

[0054] In some possible implementations of the present application, before the dynamic image is displayed according to the first RGB image data, the image processing method provided by the embodiments of the present application can further include: in the case where the color gamut corresponding to the first color space conversion type is the BT2020 color gamut, converting the first RGB image data from the BT2020 color gamut to the P3 color gamut to obtain second RGB image data; and correspondingly, displaying the dynamic image according to the first RGB image data includes: displaying the dynamic image according to the second RGB image data.

[0055] Exemplarily, when the second color space conversion type is BT2020_YUV2RGB, the color gamut of the obtained first RGB image data is the BT2020 color gamut, the first RGB image data is converted from the BT2020 color gamut to the P3 color gamut to obtain the second RGB image data, and the second RGB image data is sent to the layer synthesis module in the DPU image synthesis unit to be synthesized with other layers into an RGB image in the P3 color gamut for display on the screen.

[0056] In some embodiments of the present application, the image processing method provided by the embodiments of the present application can further include: in the case where the second color space conversion type information fails to be written into the file header or the second color space conversion type information is not obtained by decoding the dynamic image file, performing color space conversion on the YUV image data according to BT709_YUV2RGB to obtain RGB image data; wherein the YUV image data is the YUV image data obtained by decoding the dynamic image file.
