Description
Technical Field
The invention relates to the technical field of video processing, in particular to a video OSD display method, a computer device for realizing the method and a computer readable storage medium.
Background
Many electronic devices have a video playing function, and in order to improve user experience during video playing, many electronic devices have a man-machine interaction function, and usually need to add an osd (on Screen display) image for displaying information such as menus, graphics, and characters on the basis of an original video. Therefore, it is necessary to generate an OSD image at the time of playing video and overlay the OSD image on a designated area.
The method for generating the OSD image is more, and the simpler method is to determine the position to be replaced in the video image after determining the position of the OSD image, that is, to determine the coordinate information of the pixel points to be replaced, including the row coordinate and the column coordinate of each pixel point, and to determine the color of each pixel point to be replaced, and to store the information. And when the OSD image is generated, drawing the OSD image according to the coordinates and the replaced colors of each pixel point. Although the method is simple, the method needs to store a large amount of information of the pixel points corresponding to a scene with a large number of pixels needing to be replaced and a large amount of redundant space, and particularly in a main controller with a strict requirement on memory space, the OSD image often occupies too much memory space, which makes the realization of other functions difficult.
The Chinese patent application CN107786872A discloses an OSD framework for realizing real-time square decoding by a line buffer area, the framework is provided with a Flash memory, a square coding image decoding module, an OSD display module and an LCD output module, the Flash memory is used for storing data, and the output format is RGB format after the pixels in the image are decoded; the square coding image decoding module utilizes the line buffer area to solve specific pixel points in the image in real time. The OSD architecture may be used to generate an OSD image, and in particular, divide the OSD image into a plurality of blocks by pixels, and store color data for each block. However, this method needs to add an additional Flash memory as a line buffer, and meanwhile, the data is compressed by using a compression technology derived based on block coding, and the compression ratio is only 8: 1, and at the same time, the generated OSD image has a little detail loss due to the lossy compression schedule.
Disclosure of Invention
The first purpose of the invention is to provide a video OSD display method with less data storage and lower requirement on the main controller.
The second objective of the present invention is to provide a computer apparatus for implementing the above video OSD displaying method.
A third object of the present invention is to provide a computer readable storage medium for implementing the above video OSD display method.
In order to achieve the first object of the present invention, the video OSD displaying method provided by the present invention includes obtaining an index information table of an OSD region, where the index information table includes line index information and grouping information, each line index information corresponds to at least one group of grouping information, and a plurality of pixel points corresponding to the same grouping information are continuous and have the same color; the row index information comprises row coordinates of the row pixel points; the grouping information comprises column index information of each group of pixel points of the row of pixel points, wherein the column index information of a group of pixel points comprises column initial coordinates of the group of pixel points, lengths of the pixel points and color information of the group of pixel points; drawing each line of pixel points according to the information of the index information table to form an image of an OSD region; and displaying the image of the OSD area in a preset area of the video image.
According to the scheme, the index information table of the OSD region does not store the coordinates of each pixel point and the color information of each pixel point, but groups each line of pixel points, divides a plurality of continuous pixel points with the same color into one group, and only stores the initial position, the color and other information of each group of pixel points in the group information. Therefore, when the OSD image is drawn, the color of each pixel point can be determined according to the grouping information, and the data volume required to be recorded by the index information table is greatly reduced, so that the index information storage data volume of the OSD region is less, the occupied hardware resources are less, and the data processing efficiency of the main controller can be improved.
Preferably, the row index information further includes the grouping number of the row pixels. Therefore, when the image in the OSD area is drawn, whether grouping of the pixel points in the row is omitted or not can be counted, the color information of each pixel point can be calculated more accurately, and the drawing quality of the image in the OSD area is improved.
Further, each group of pixel point column index information further comprises a column termination coordinate of the group of pixel points.
Therefore, when each line of pixel points are drawn, the color of each pixel point can be calculated more accurately, and the problem of color error of the drawn image in the OSD region is solved.
The further proposal is that the column index information of a plurality of groups of pixel points in the same row of pixel points is continuously stored. Preferably, the column index information of each group of pixels in the same row of pixels is stored according to the initial column coordinate sequence of each group of pixels.
Therefore, when a row of pixel points are drawn, the color of each pixel point can be calculated in sequence according to the reading sequence of each row of index information, and the image drawing efficiency of an OSD region is improved.
Further, the color information of each group of pixel points is YUV information or RGB information.
Since YUV information or RGB information is common information representing image colors, the use of the two kinds of information can simplify the drawing of an OSD region image.
Further, before obtaining the index information table of the OSD region, the following steps are performed: generating an index information table according to the color information of each pixel point in the OSD area: grouping the pixel points of each line according to the color of each pixel point of the pixel points of each line, wherein the pixel points of the same group are continuous and have the same color; recording the column initial coordinates of each group of pixel points, the lengths of the pixel points and the color information of the group of pixel points to form column index information of each group of pixel points; and recording the line coordinates and the grouping number of the pixels in each line to form line index information of the pixels in each line.
Therefore, when the index information table of the OSD region is generated, the pixel points in each line are grouped according to colors, and the stored column index information only comprises the column initial coordinates, the lengths of the pixel points and the color information of the group of pixel points, but does not need to store the coordinates and the color information of each pixel point, so that the storage amount of the color information of the image in the OSD region can be greatly reduced, and the drawing efficiency of the image in the OSD region can be improved.
In order to achieve the second objective mentioned above, the present invention provides a computer apparatus including a processor and a memory, wherein the memory stores a computer program, and the computer program realizes the steps of the video OSD display method when executed by the processor.
To achieve the third objective, the present invention provides a computer-readable storage medium having a computer program stored thereon, where the computer program is executed by a processor to implement the steps of the video OSD display method.

Detailed Description
The video OSD display method of the invention is applied to the intelligent electronic equipment with video playing capability, preferably, the intelligent electronic equipment is provided with a display screen, the video image can be displayed on the display screen, and the OSD image can be displayed on the video image. Preferably, the intelligent electronic device is provided with a processor and a memory, the memory stores a computer program, and the processor implements the video OSD display method by executing the computer program.
The embodiment of the video OSD display method comprises the following steps:
in view of the problem of large storage capacity of the traditional OSD image data, the embodiment provides a new OSD display method, which reduces the storage data amount of the OSD image by compressing and storing the OSD image data, and can reduce the operation amount of the main controller when the OSD image is generated, so that the main controller can have more resources to process other programs, and the operation performance of the electronic device is improved.
The method of the embodiment mainly comprises the steps of generating an index information table of the OSD regional image and drawing two parts of the OSD regional image by applying the index information table. The following describes a process of generating an index information table of an OSD region image with reference to fig. 1.
First, step S1 is executed to obtain color information of each pixel in the OSD region that needs to be generated. Generally, an OSD region added to a video image is a rectangular or circular region, which is composed of a plurality of pixels arranged in a plurality of rows and columns, and each pixel has its own color. Generally, color information of a pixel point is represented using YUV color information or RGB color information. In step S1, coordinate information of each pixel point and color information of each pixel point in the OSD region are obtained, and the coordinate and the color information of each pixel point are obtained in a one-to-one correspondence.
Then, step S2 is executed to obtain information of a row of pixels. In this embodiment, for the OSD region, the information of each line of pixel points is obtained from top to bottom, and therefore, the information of the first line of pixel points located at the uppermost end of the OSD region is obtained first. The acquired information of each pixel point comprises the column coordinates and the color information of the pixel point. Since the row coordinate of the pixel point in the row is known, the row coordinate of the pixel point does not need to be obtained in step S2.
Next, step S3 is executed to group the current line of pixels, and divide the line of pixels into one or more groups. The basis for grouping the pixels in a row is that the pixels in the same group are continuously arranged and have the same color. Referring to fig. 2, the first row of pixels includes eight pixels, i.e., pixels 00, 01, 02, 03, 04, 05, 06, and 07, wherein the colors of the eight pixels are red, yellow, green, and green, respectively. It can be seen that the pixels 00 and 01 are continuously arranged and have the same color, and are divided into a first group of pixels, the pixels 02, 03 and 04 are continuously arranged and have the same color, and are divided into a second group of pixels, and the pixels 05, 06 and 07 are continuously arranged and have the same color, and are divided into a third group of pixels.
Similarly, in the second row of pixels, the pixels 10, 11, 12, and 13 are continuously arranged and have purple color, and are divided into a first group of pixels in the second row, the pixels 14, 15, and 16 are continuously arranged and have blue color, and are divided into a second group of pixels in the second row, and the pixel 17 is divided into a third group of pixels in the second row.
For the third row of pixels, since the pixels 20 and 21 are continuously arranged and have white colors, the third row of pixels is divided into a first group of pixels, the pixels 22 and 23 are continuously arranged and have orange colors, the third row of pixels is divided into a second group of pixels, and the third row of pixels 24, 25, 26 and 27 are continuously arranged and have white colors. It can be seen that although the color of the pixels 20 and 21 is the same as that of the pixels 24, 25, 26 and 27, the pixels are not continuously arranged, and thus the pixels are not divided into the same group of pixels.
It can be understood that if the colors of the pixels in the row are the same, the pixels in the row have only one group, that is, the pixels in the entire row are divided into the same group.
After the row of pixel points is grouped, step S4 is executed to generate grouping information of the row of pixel points. In this embodiment, the grouping information of a row of pixel points may include one or more column index information, where a column index information corresponds to a group of pixel points, and specifically, for a group of pixel points, the column index information corresponding to the group of pixel points includes a column coordinate of an initial pixel point of the group of pixel points, a length of the group of pixel points, and a color of the group of pixel points. The length of the group of pixels is the number of the group of pixels, so that the row coordinate of the termination pixel of the group of pixels can be calculated according to the initial row coordinate of the group of pixels and the number of the group of pixels. Of course, the column grouping information may also include the column coordinates of the terminating pixel of the group of pixels, so that the starting and ending positions of the pixels of each group can be determined more accurately.
In step S4, it is necessary to record the column index information of each group of pixels according to the grouping number of a line of pixels, and preferably, the column index information of each group is stored continuously, for example, sequentially according to the column coordinates of the starting pixel of each group of pixels, so that when the OSD region is drawn, the color of each pixel of each line of pixels in the OSD region can be determined quickly according to the read data.
Then, step S5 is executed to generate row index information of the row of pixels. In this embodiment, the row index information of the row of pixels includes the row coordinate and the grouping number of the row of pixels, and since the row coordinate of the row of pixels is already obtained when the row of pixels is obtained in step S2, and the grouping number of the row of pixels is already determined when the grouping is performed in step S3, step S5 is to obtain the row index information of the row of pixels after adding the row coordinate and the grouping number to the grouping information generated in step S4.
And then, executing step S6, determining whether the current line of pixels is the last line of pixels in the OSD region, if not, executing step S8, obtaining the next line of pixels, returning to step S2, grouping the newly obtained line of pixels, and generating grouping information and line index information. If the current line of pixels is the last line of pixels in the OSD region, step S7 is executed to integrate the line index information of each line of pixels to form an index information table of the OSD region, which is used to generate an image of the OSD region.
The table of index information of the OSD region image generated according to the above-described procedure is shown as follows:
TABLE 1 index information table of OSD regional images
After the index information table is generated, the embodiment will draw an image of the OSD region by using the index information table. The following describes a process of drawing an image of the OSD region with reference to fig. 3. First, step S11 is executed to obtain an OSD index information table, for example, the information in table 1, step S12 is executed to obtain the row index information and grouping information of a row of pixels, and step S13 is executed to obtain a row of pixels according to the obtained grouping information.
The obtained row index information comprises the row coordinates of the pixel points of the row, so that the row coordinates of the pixel points needing to be drawn at present can be determined. And the grouping information of each row of pixel points comprises a plurality of column index information, each column index information comprises the column coordinate of a grouped initial pixel point, the number of the group of pixel points and the color information of the group of pixel points, and a group of pixel points can be rapidly drawn according to the information.
Then, step S14 is executed to determine whether the current line of pixels is the last line of pixels in the OSD region, if not, step S17 is executed to obtain the next line of pixels, and step S12 is returned to, obtain the line index information and the grouping information of the new line of pixels, and draw the new line of pixels. If the current line of pixels is the last line of pixels in the OSD region, step S15 is executed to integrate the drawn lines of pixels to generate an image of the OSD region, and step S16 is executed to display the generated image of the OSD region at a preset position in the video image, for example, at the top left corner or the top right corner in the video image.
Therefore, compared with the traditional storage method of the OSD image information, the storage space occupied by the OSD index information table generated by the embodiment is very small, the performance requirement of the main controller for generating the OSD regional image can be reduced, and the efficiency of generating the OSD regional image is improved.
Specifically, by applying the conventional storage method for OSD image information, each pixel point needs to store a row coordinate (2 bytes), a column coordinate (2 bytes), and color information (3 bytes), and for example, with a resolution of 640 × 480, a storage space of 2.05M bytes needs to be used.
In the scheme of this embodiment, in the row index information, the row coordinates are stored with 2 bytes, the grouping number is stored with 2 bytes, and 480 rows are total, and in the column index information, the initial column coordinates of the pixel points are stored with 2 bytes, the group of pixel points is stored with 2 bytes, the grouping color information is stored with 3 bytes, and 480 rows are total, so the total storage space is 5280 bytes, i.e., 5.16KB, which can greatly reduce the storage space compared with the conventional storage method.
