For the convenience of understanding of the present embodiment, the image processing method of the present embodiment will be described in detail below with reference to fig. 2 to 4. Specifically, the image processing method will be described in detail by taking as an example that the image processor 200 shown in fig. 2 executes the image processing method according to the embodiment of the present invention.
Fig. 2 is a schematic diagram of an image processor 200, wherein the image processor 200 includes an input interface 202, a microprocessor 204, a programmable logic device 206, a non-volatile memory 208, a volatile memory 210, and an output interface 212. The input interface 202 is electrically connected to the programmable logic device 206. The microprocessor 204 is electrically connected to a non-volatile memory 208 and a programmable logic device 206. The programmable logic device 206 is electrically connected to the non-volatile memory 208, the volatile memory 210, and the output interface 212.
As mentioned above, the input Interface 202 may be, for example, an HDMI (High Definition Multimedia Interface) Interface, a DP (display Interface) Interface or a DVI (Digital Visual Interface) Interface; the microprocessor 204 may be, for example, an MCU (Micro controller Unit); the Programmable logic device 206 may be, for example, an FPGA (Field-Programmable Gate Array); the nonvolatile memory 208 may be, for example, an EMMC (Embedded MultiMedia Card); the volatile memory 210 may be, for example, a DDR (Double Data Rate); the output Interface 212 may be, for example, an HDMI (High Definition Multimedia Interface) Interface, a DVI (Digital Visual Interface) Interface, but the invention is not limited thereto. The programmable logic device 206 receives an input video source, i.e., a target input source, through the input interface 202, and in response to receiving configuration parameters, such as resolutions of an input image and an output image, sent by the microprocessor 204, such as an MCU (Micro controller Unit), the programmable logic device 206 processes the target input source to obtain a target output image and a target mirrored output image, and outputs the target output image and the target mirrored output image through the output interface 212.
In particular, the programmable logic device 206, such as an FPGA, implements the image mirroring functionality by executing image processing software thereon, which may, for example, include an input scaling module, a mirroring processing module, and a plurality of output scaling modules, divided by functional modules. An image processing method according to an embodiment of the present invention will be described below with reference to fig. 3.
First, the programmable logic device 206 obtains a video source, for example, a target input source, then, an input scaling module of the programmable logic device 206 performs input scaling processing on the target input source to obtain a processed input source, and stores the processed input source in a volatile memory 210, for example, a DDR, and then the programmable logic device 206 reads at least a part of stored image data of the processed input source according to an image output parameter sent by a microprocessor 204, for example, an MCU, to obtain target image data, where the image output parameter may be, for example, start position information, image width information, and height information stored in the DDR for the target image data. Although there is only one output scaling module corresponding to the target output image and the target mirror output image in fig. 3, in practical applications, the number of output scaling modules corresponding to the target output image and the target mirror output image may also be multiple, and is not limited herein. It is worth mentioning that, if the target image data is output by being scaled by the plurality of output scaling modules, the image output parameters include start position information, image width information, and height information, which are specifically stored in the DDR, of the corresponding portion of the target image data that is processed by each output scaling module. Then, the output scaling module of the programmable logic device 206 performs a first output scaling process on the target image data according to the configuration parameters sent by the microprocessor 204 to obtain a target output image, and outputs the target output image.
The programmable logic device 206 further adjusts the arrangement order of the pixels in the target image data through the mirror image processing module to obtain the image data after mirror image processing, and a specific process of obtaining the image data after mirror image processing is shown in fig. 4. Fig. 4 shows a process of performing horizontal mirroring on target image data, which is to adjust an arrangement order of pixel points in the target image data and keep the arrangement order of each pixel row in the target image data unchanged. Further, the horizontal mirroring process specifically includes: reversing the arrangement sequence of each pixel unit of each pixel row in the target image data to obtain reversed image data; performing data bit reverse order on each pixel point component in each pixel unit of each pixel row in the reversed image data to obtain image data after the reverse order; and reforming each pixel point in each pixel unit of each pixel row in the image data after the reverse order to obtain the image data after the mirror image processing. In connection with fig. 4, the resolution of the target image data is 1080p, i.e. the target image data comprises 1080 × 1920 pixels, i.e. each line of the target image data has 1920 pixels. Taking a horizontal mirroring process of one pixel row as an example, first, the bit number of the pixel unit is determined according to the read/write parameters of the volatile memory, such as DDR, e.g., the memory bit width, the memory parallel number and the read-ahead address number, for example, the bit width of the DDR used in the embodiment of the present invention is 16 bits, i.e., the memory bit width is 16, the DDR used in the embodiment of the present invention is 4 pieces of DDR used in parallel, i.e., the memory parallel number is 4, and 8 addresses are prefetched when one DDR reads an address, i.e., the number of prefetched addresses is 8, therefore, when the programmable logic device 206 accesses the DDR, the target image data stored in the embodiment of the present invention is read by using 16 × 4 × 8 ═ 512 bits as one pixel unit, so that each pixel point has three pixel components, i.e., a red (R) component, a green (G) component and a blue (, each pixel component needs 8 bits when stored, and therefore, one pixel row, that is, 1920pixel is 1920 × 3 × 8bit is 90 × 512bit, so that it can be obtained that each pixel row has 90 pixel units, and when horizontal mirroring processing is performed, address inversion is performed on each row of pixel units by taking the pixel units as a unit, that is, the arrangement sequence of each pixel unit of each pixel row in the target image data is reversed, that is, the whole arrangement sequence of the pixel units in the first row of pixels in fig. 4 is subjected to reverse order processing, that is, the whole arrangement sequence of the 90 pixel units is subjected to reverse order arrangement, so as to obtain reversed image data; then, performing data bit reverse order on each pixel point component in each pixel unit of each pixel row in the reversed image data to obtain image data after the reverse order; finally, reforming each pixel point in each pixel unit of each pixel row in the image data after the reverse order, that is, arranging pixel point components corresponding to each pixel point in each row according to the order of R, G, B to obtain the image data after the mirror image processing, for example, as shown in fig. 4, the storage order of the pixel point components B1, G1, and R1 is adjusted to R1, G1, and B1.
After the horizontal mirroring is performed on the target image data, the programmable logic device 206 performs a second output scaling process on the mirrored image data by using an idle scaling process resource, that is, an output scaling module that is not used during the first scaling process, to obtain a target mirrored image output image, and outputs the target mirrored image output image. Here, in order to realize that the target mirror image output image and the target output image are in a mirror image relationship, the number of output scaling modules corresponding to the target output image is the same as the number of output scaling modules corresponding to the target mirror image output image.
In an embodiment of the present invention, the performing the input scaling processing on the target input source to obtain the processed input source includes: carrying out reduction processing on the target input source to obtain the processed input source; performing a first output scaling process on the target image data by using a scaling processing resource to obtain a target output image, including: performing first amplification processing on the target image data to obtain a target output image; the second output scaling processing is performed on the image data after the mirror image processing to obtain a target mirror image output image, and the method comprises the following steps: the image data after the mirror image processing is subjected to the second amplification processing to obtain the target mirror image output image, that is, when the programmable logic device 204 performs the scaling processing, the image reduction processing is performed before the DDR stores the data, and then the image amplification processing is performed, so that the DDR bandwidth is saved, and the hardware resource of the image processor 200 is saved.
In the scheme, a processed input source is obtained by performing input zooming processing on the target input source, the processed input source is stored, at least part of image data of the stored processed input source is read according to image output parameters to obtain target image data, first output zooming processing is performed on the target image data by using zooming processing resources to obtain a target output image, and the target output image is output; adjusting the arrangement sequence of the pixel points in the target image data to obtain image data after mirror image processing; and performing second output scaling processing on the image data subjected to the mirror image processing by using idle scaling processing resources to obtain a target mirror image output image, and outputting the target mirror image output image, so that the target output image and the target mirror image output image in mirror image with the target output image are obtained under the condition of not increasing resource overhead.
