In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention. Referring to fig. 1, the method includes:
101. and acquiring the image bit width of the first image.
The first image is an image to be processed, and the image bit width is a bit number of each pixel in the image, which determines the color number of each pixel. For example, the image Bit widths may include a first Bit width (8Bit), a second Bit width (10Bit), a third Bit width (12Bit), and other type Bit widths. Taking 8 bits as an example, the image Bit width is 8 bits, which indicates that each pixel corresponds to 8 bits in the memory.
102. And determining an image processing channel corresponding to the image bit width according to the image bit width, wherein different image bit widths correspond to different image processing channels.
Different image processing channels are used for processing images with different image bit widths, and different image processing algorithms can be configured for different image processing channels. For example, a plurality of processing modules for implementing respective image processing algorithms may be configured in the image processing channel. Different processing modules are configured in different image processing channels, so that different image processing algorithms are realized, the targeted processing of different color gamuts can be realized, and the image quality under different bit widths is ensured.
103. And processing the first image through an image processing channel corresponding to the image bit width to obtain a second image.

According to the method provided by the embodiment of the invention, the image bit width of the input image is automatically acquired, the corresponding image processing channel is selected to process the image, and different image bit widths correspond to different image processing channels, so that even if the images with different image bit widths are input, the images with different image bit widths can be processed through the corresponding image processing channels, and the compatible processing of different image bit widths is realized. And because images with different image bit widths can be processed by selecting respectively proper image processing channels, the optimal image processing effect can be ensured.
Fig. 2 is a flowchart of an image processing method according to an embodiment of the present invention. Referring to fig. 2, the method includes:
201. first image and SDI auxiliary data input through an SDI interface are received.
In the embodiment of the present invention, when the electronic device receives the input first image through the SDI interface, the electronic device may further acquire SDI auxiliary data. For example, after the camera device captures a video image, the video image can be transmitted to the electronic device in real time through the SDI interface in the form of a data stream, and meanwhile, the SDI auxiliary data is superimposed at a gap in the data stream that does not affect normal image data, so that the electronic device can receive the image and the SDI auxiliary data at the same time. Of course, the electronic device may also be the image capturing device, which is not limited in the embodiment of the present invention.
In The SDI standard (for example, SMPTE-425M standard) of The Society of Motion Picture and Television Engineers, SDI auxiliary data includes a load flag (load Identifier), includes a definition of The Bit width of The currently transmitted image therein, and can indicate four different Bit widths, i.e., a first Bit width (8Bit), a second Bit width (10Bit), a third Bit width (12Bit), and other types of Bit widths. Therefore, the electronic device may acquire an image bit width of the first image according to the SDI auxiliary data.
202. And acquiring the image bit width of the first image according to the load mark extracted from the SDI auxiliary data.
In the embodiment of the present invention, after receiving an input image and SDI auxiliary data, an electronic device may extract a load flag from the SDI auxiliary data, and further acquire an image bit width of the first image according to the load flag.
In a possible implementation manner, the electronic device may obtain an image bit width of the first image according to values of a first bit and a second bit in the designated byte of the load flag. For example, the load flag may include 4 bytes, such as Byte1, Byte2, Byte3, and Byte4, wherein Byte4 is the designated Byte. Each byte may include 8 bits, Bit0, Bit1, … …, Bit7, etc., where Bit0 is the first Bit and Bit1 is the second Bit.
In the load flag extraction and bit width judgment, the electronic device may refer to the SDI standard of SMPTE. Specifically, when the values of the first bit and the second bit are both first values, determining that the image bit width of the first image is a first bit width; when the value of the first bit is the first numerical value and the value of the second bit is the second numerical value, determining that the image bit width of the first image is a second bit width; when the value of the first bit is the second numerical value and the value of the second bit is the first numerical value, determining that the image bit width of the first image is a third bit width; and when the values of the first bit and the second bit are the second numerical value, determining that the image bit width of the first image is other types of bit widths except the first bit width, the second bit width and the third bit width.
For example, the first value is 1, the second value is 0, the first Bit width is 8 bits, the second Bit width is 10 bits, and the third Bit width is 12 bits. Accordingly, when Bit1 is 0 and Bit0 is 0 in Byte4 of the load flag, it is determined that the image Bit width of the image is 8 bits; when Bit1 is 0 and Bit0 is 1 in Byte4 of the load flag, determining that the image Bit width of the image is 10 bits; when Bit1 is 1 and Bit0 is 0 in Byte4 of the load flag, determining that the image Bit width of the image is 12 bits; when Bit1 is 1 and Bit0 is 1 in Byte4 of the load flag, the image Bit width of the image is determined to be other types of Bit widths than 8Bit, 10Bit, and 12 Bit. The Bit width of the other type may be customized, for example, the Bit width of the other type is customized to be 14 bits, which is not limited in the embodiment of the present invention.
It should be noted that, the above steps 201 to 202 are one possible implementation manner of acquiring the image bit width of the first image. The image Bit width of the first image is obtained according to the values of Bit1 and Bit0 in the Byte4 of the load mark, and an effective mode for automatically identifying the image Bit width is provided, so that the electronic equipment can select a corresponding image processing channel to process the image according to the automatically identified image Bit width, and the optimal image processing effect is realized.
203. And determining an image processing channel corresponding to the image bit width according to the image bit width, and processing the first image through the image processing channel corresponding to the image bit width to obtain a second image, wherein different image bit widths correspond to different image processing channels.
In the embodiment of the present invention, the electronic device may be provided with a plurality of image processing channels, each image processing channel is configured to process images with different image bit widths, the image processing channels with different image bit widths are configured with different image processing algorithms, and each image processing channel implements a corresponding image processing algorithm when processing an image.
For example, the electronic device may set a corresponding number of image processing channels according to the number of types of image bit widths. Accordingly, after the electronic device obtains the image bit width, a corresponding image processing channel may be allocated to the image according to the image bit width. For example, the image Bit width has two types, 8Bit and 10Bit, the electronic device can set 2 image processing channels and configure 2 image processing algorithms. Similarly, if the image Bit width has three types, i.e., 8Bit, 10Bit, and 12Bit, the electronic device may set 3 image processing channels and configure 3 image processing algorithms.
After obtaining the image bit width of the first image, the electronic device may input the first image into the corresponding image processing channel for processing according to the image bit width, which not only can implement compatible processing of different image bit widths, but also can ensure the optimal processing effect of the image.
Compared with the related art in which only specific image bit width is supported, the problem that the image bit width is incompatible and the image cannot be processed easily occurs, or the problem that the image quality is lost after processing easily occurs by adopting simple processing modes such as shifting and 0 complementing. In the embodiment of the invention, different image processing channels are selected according to different image Bit widths to process the input image, so that the targeted processing of different color gamuts such as BT709 (usually 8 bits) and BT2020(10 bits) can be realized, the compatible processing of different image Bit widths can be realized, and the image quality under different Bit widths can be ensured.
204. And according to the encapsulation mode corresponding to the image bit width, after the second image is encapsulated, outputting the encapsulated second image through an output interface.
In the embodiment of the present invention, the electronic device is provided with an output interface, and the output interface can be used for outputting image processing results with different image bit widths, that is, a second image. The output interface may perform different encapsulation (packaging) methods for different image bit widths, and after the electronic device completes image processing in step 203 to obtain the second image, the electronic device may encapsulate the second image according to the encapsulation method corresponding to the image bit width of the first image. When packaging, the electronic device can only package the effective image data, and filter out other data such as load marks.
In one possible implementation, when determining the image processing channel corresponding to the image bit width, the electronic device may also determine an output control channel corresponding to the image bit width. Different image bit widths correspond to different output control channels, and the different output control channels adopt different packaging modes to package data; furthermore, the electronic device may package the second image according to a packaging manner corresponding to the image bit width, including: and packaging the second image through an output control channel corresponding to the image bit width. For example, the electronic device may set a corresponding number of output control channels according to the number of types of image bit widths. Accordingly, after the second image is obtained, the output control channel corresponding to the image bit width may encapsulate the second image. By setting the image processing channels and the output control channels with corresponding quantity according to the quantity of the image bit width, the optimal image processing effect and the optimal matching bit width output channel can be ensured to be available for each image bit width.
It should be noted that step 204 is an optional step, and the embodiment of the present invention only takes the example that the electronic device encapsulates and outputs the second image obtained after the first image is processed as an example, and provides a possible implementation manner for outputting the image processing result.
In the embodiment of the present invention, in order to process multiple image bit widths compatibly, the electronic device may be provided with multiple image processing channels, and when an image with any image bit width is input to the electronic device, the electronic device may select a corresponding image processing channel to process according to the image bit width, where only one image processing channel among the multiple image processing channels actually performs an image processing process. Therefore, before outputting the encapsulated second image through the output interface, the electronic device needs to perform output channel gating, that is, according to the image bit width, communicate the image processing channel corresponding to the image bit width, the output control channel corresponding to the image bit width, and the output channel between the output interface, and output the encapsulated second image through the output interface based on the output channel.
In the above steps, the image bit width of the first image input by the SDI interface is judged, then the corresponding image processing channel is selected, and after the processing is completed, the second image is output from the output channel corresponding to the image bit width. Referring to fig. 3, a schematic flow chart of a processing method compatible with different image bit widths is provided, as shown in fig. 3, an electronic device first receives a first image input by an SDI interface, extracts a load flag in SDI auxiliary data, determines a current image bit width, selects a corresponding processing channel and an output control channel according to the image bit width, and finally performs output channel gating to output a processed second image through an output interface. The electronic device may be provided with N image processing channels, such as an image bit width 1 processing channel, an image bit width 2 processing channel, … …, and an image bit width N processing channel, and N output control channels, such as an image bit width 1 output control channel, an image bit width 2 output control channel, … …, and an image bit width N output control channel. Where N is a natural number, the electronic device may set N according to the Bit width number of the image subjected to the compatible processing, for example, if the electronic device is subjected to the compatible processing for two types of image Bit widths, i.e., 8Bit and 10Bit, the N is 2, if the electronic device is subjected to the compatible processing for three types of image Bit widths, i.e., 8Bit, 10Bit and 12Bit, the N is 3, and if the electronic device is subjected to the compatible processing for four types of image Bit widths, i.e., 8Bit, 10Bit, 12Bit and 14Bit, the N is 4.
The following describes the scheme of the present invention in further detail by taking the electronic device compatible processing of two image Bit widths of 8Bit and 10Bit as an example through steps a to e, and the Bit widths of other images are the same.
Step a, receiving a first image input by the SDI interface, extracting a load flag in the SDI auxiliary data, indicating that the current image Bit width is 8 bits if Bit1 and Bit0 in Byte4 are 0 and indicating that the current image Bit width is 10 bits if Bit1 and Bit0 are 1.
And b, selecting a correct image processing channel according to the judged image bit width by the processing channel distribution process.
And c, if the image Bit width is 8 bits, selecting an image processing channel of 8 bits, wherein the data processing Bit width in the image processing channel supports the image Bit width processing of 8 bits, and if the image Bit width is 10 bits, selecting an image processing channel of 10 bits in the same manner to finish the image processing.
And d, receiving the image processing result with the corresponding bit width by the output control channel, and finishing data encapsulation according to the requirement of the output interface.
And e, finally, carrying out output channel gating according to the image bit width, and outputting the effective image data through an output interface. Thus, compatible processing of 8-Bit and 10-Bit image Bit widths is completed.
By utilizing the load mark of the SDI standard protocol, the image bit width input by the SDI interface is automatically identified, and meanwhile, the image processing channel and the image output control channel with corresponding bit width are automatically switched, so that the optimal image processing and transmission effects are ensured, and the self-adaptive processing of different image bit widths is realized.
According to the method provided by the embodiment of the invention, the image bit width of the input image is automatically acquired, the corresponding image processing channel is selected to process the image, and different image bit widths correspond to different image processing channels, so that even if the images with different image bit widths are input, the images with different image bit widths can be processed through the corresponding image processing channels, and the compatible processing of different image bit widths is realized. And because images with different image bit widths can be processed by selecting respectively proper image processing channels, the optimal image processing effect can be ensured.
