In the following, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure.

Fig. 1A is a schematic view of an implementation flow of a screen display method according to an embodiment of the disclosure, as shown in fig. 1A, the method includes steps S11 to S14, where:

step S11, responding to a display instruction for displaying a first OSD image, and determining a first storage node matched with the display instruction from at least one storage node in a preset linked list; each storage node in the linked list is used for storing the associated information of one OSD image block.

Here, the display instruction is to display the first OSD image. Different display instructions may correspond to different first OSD images. The display instruction may be generated by a user operation, automatically generated by the electronic device, received by an instruction sent by another device, or the like. The user operation may include, but is not limited to, a gesture, voice, body feeling, and the like. In implementation, a person skilled in the art may autonomously determine a generation manner of the display instruction according to actual requirements, and the embodiment of the present disclosure is not limited.

For example, the user performs a preset operation gesture on the electronic device to generate the display instruction. For another example, after the electronic device is powered on, the display instruction for displaying the first OSD image is generated. For example, the electronic device receives an instruction transmitted from another device, and uses the instruction as the display instruction.

The first OSD image may be an image in any suitable scene. For example, the first OSD image may be a system menu. For another example, the first OSD image may be an image of an alert, such as an image of a person who is not wearing a seat belt. In some embodiments, the first OSD image may be a fixed image or a customized image. The first OSD image includes at least one OSD image block. In implementation, the first OSD image may be stored in at least one storage node.

The linked list may include, but is not limited to, a single linked list, a double linked list, a circular linked list, and the like. In implementation, a person skilled in the art may autonomously determine an implementation form of the linked list according to actual requirements, and the embodiment of the present disclosure is not limited.

In some embodiments, the correspondence between the display instruction and the first storage node may be established in advance, and the correspondence may be stored in the electronic device or in another electronic device. And under the condition that the corresponding relation is stored in the electronic equipment, the electronic equipment determines a first storage node matched with the display instruction in the corresponding relation according to the display instruction. And under the condition that the corresponding relation is stored in other electronic equipment, the electronic equipment sends the display instruction to the other electronic equipment, so that the other electronic equipment determines a first storage node matched with the display instruction in the corresponding relation according to the display instruction, and returns the first storage node to the electronic equipment. In implementation, a person skilled in the art may autonomously determine a corresponding relationship between the display instruction and the first storage node according to actual requirements, and the embodiment of the present disclosure is not limited.

In some embodiments, the correspondence between the display instruction and the first storage node may be determined based on a preset rule. The preset rules may include, but are not limited to, default configuration of the electronic device, user customization, user preferences, frequency of use, user operation information, and the like. In implementation, a person skilled in the art may set the preset rule autonomously according to actual requirements, and the embodiment of the present disclosure is not limited.

For example, the electronic device provides a configuration option by which the user can customize the correspondence.

For another example, the corresponding relationship may be determined based on attribute information of the user operation, wherein the attribute information may include, but is not limited to, a type, a distance, a speed, a position, a duration, a number of times, a strength, and the like of the operation. In implementation, a person skilled in the art may autonomously set a relationship between the attribute information of the operation and the corresponding relationship according to an actual requirement, and the embodiment of the present disclosure is not limited.

In some embodiments, the determination may be based on the type of operation, i.e., different types correspond to different correspondences. For example, when the operation gesture is a sliding operation, the corresponding relationship is a first corresponding relationship, and the first corresponding relationship includes that the first corresponding relationship corresponds to a first storage node when clicking, and the second corresponding relationship corresponds to a second storage node when double clicking; when the operation gesture is a pressing operation, the corresponding relationship is a second corresponding relationship, and the second corresponding relationship comprises that the last storage node is corresponding when the O is drawn, the first storage node is corresponding when the X is drawn, and the like.

In some embodiments, the correspondence may be determined in real time based on the strength of the operation, i.e., different strengths correspond to different correspondences. For example, in the case where the pressing force degree falls within the first range, the correspondence relationship is a first correspondence relationship; when the pressing force degree falls within the second range, the correspondence relationship is a second correspondence relationship.

In some embodiments, the association information may include, but is not limited to, chain domain information, color information, and the like. The color information may include, but is not limited to, a color mapping table, a color index value, and the like. In some embodiments, the color information may also include basic attribute information of the image block. The basic attribute information may include, but is not limited to, size, position, transparency, color depth, and the like. Different color depths represent different color modes. Color depths may include, but are not limited to, 256 colors, 128 colors, 16 colors, other color depths, and the like.

The chain domain information at least comprises address information for characterizing at least one OSD image block associated with the OSD image. For example, for a single linked list, the link domain information includes right link domain information, and the right link domain information includes address information of a next storage node associated with the first storage node; for the double-chain table and the circular linked list, the chain domain information further includes left chain domain information, and the left chain domain information includes address information of a previous storage node associated with the first storage node. In some embodiments, the right-chain domain information may further include, but is not limited to, address information of the first storage node, basic attribute information of the image block, and the like.

Fig. 1B is a schematic diagram of a composition structure of a double-linked list provided in the embodiment of the present disclosure, as shown in fig. 1B, the double-linked list includes four storage nodes, i.e., a storage node 111, a storage node 112, a storage node 113, and a storage node 114, where each storage node includes three parts, that is: a data part 101 (corresponding to the aforementioned color information and basic attribute information of the image block), left-chain domain information 102, and right-chain domain information 103. The storage node 111 is a header of the doubly linked list, which indicates that the storage node 111 does not have a predecessor node, that is: the address information in the left-chain domain information 102 in the storage node 111 is NULL, and the right-chain domain information 103 includes the address information 1080 of the storage node 112; the left-chain domain information 102 in the storage node 112 includes the address information 1050 of the storage node 111, and the right-chain domain information 103 includes the address information 1036 of the storage node 113; the left-chain domain information 102 in the storage node 113 includes address information 1080 of the storage node 112, and the right-chain domain information 103 includes address information 1170 of the storage node 114; the storage node 114 is a table tail of the double-linked list, which indicates that the storage node 114 has no successor node, that is: the address information in the right-chain domain information 103 in the storage node 114 is NULL, and the left-chain domain information 102 includes the address information 1036 of the storage node 113.

In some embodiments, the association information may be stored in a structured manner in the first storage node.

For example, for a doubly linked list, the structure of the association information may be:

{

v left chain domain information &

Address information of a previous first storage node;

v. Right chain Domain information

Address information of the first storage node;

address information of a next first storage node;

basic attribute information of the image block;

v color information +

A color mapping table;

}

Fig. 1C is a schematic diagram illustrating a structure for associating information in a double-linked list according to an embodiment of the present disclosure, where as shown in fig. 1C, the double-linked list includes two storage nodes, that is: the structure of the associated information in each storage node is the same, and the structure is: address information 1201 of the previous first storage node, address information 1202 of the first storage node, address information 1203 of the next first storage node, basic attribute information 1204 of the image block, a color mapping table 1205, and a color index value 1206.

And step S12, determining at least one target OSD image block based on the associated information in the first storage node.

Here, the at least one target OSD image block may include, but is not limited to, one generated based on color information in the first storage node, one generated based on chain domain information in the first storage node, and the like.

For example, in the case that the linked list is a single linked list, a target OSD image block is generated based on the color information in the first storage node; if the address information in the right-chain domain information of the first storage node is empty, the next first storage node does not exist, and the searching is stopped; if the address information in the right-chain domain information of the first storage node is not empty, it indicates that a next first storage node exists, at this time, a next first storage node is obtained based on the address information, and at least one target OSD image block is determined based on the associated information of the next first storage node, and the process is circulated until the address information in the obtained right-chain domain information of the storage node is empty.

For another example, in the case that the linked list is a double linked list, a target OSD image block is generated based on the color information in the first storage node; if the address information in the left-chain domain information of the first storage node is null, the last first storage node does not exist, and the searching is stopped; if the address information in the right-chain domain information of the first storage node is null, indicating that the next first storage node does not exist, stopping searching; if the address information in the left-chain domain information of the first storage node is not empty, indicating that a last first storage node exists, obtaining a last first storage node based on the address information, and determining at least one target OSD image block based on the association information of the last first storage node, and circulating the steps until the determined address information in the left-chain domain information of the last first storage node is empty; and if the address information in the right-chain domain information of the first storage node is not null, indicating that a next first storage node exists, obtaining a next first storage node based on the address information, determining at least one target OSD image block based on the associated information of the next first storage node, and circulating the steps until the address information in the obtained right-chain domain information of the storage node is null.

And S13, generating the first OSD image based on each target OSD image block.

Here, each target OSD image block is preprocessed to generate the first OSD image. Among other things, preprocessing may include, but is not limited to, stitching, denoising, scaling, and the like. For example, in a case that a first OSD image includes a target OSD image block, the target OSD image block is regarded as the first OSD image. For another example, when the first OSD image includes at least two target OSD image blocks, each target OSD image block is subjected to processing such as stitching and denoising to generate the first OSD image.

And S14, generating the picture based on the first OSD image, and displaying the picture.

Here, the screen may include the first OSD image, and may also include the first OSD image and other images. For example, the first OSD image is taken as the screen. For another example, the image to be displayed and the first OSD image are aliased to obtain the picture.

In the embodiment of the disclosure, a first storage node matched with a display instruction is determined from at least one storage node in a preset linked list by responding to the display instruction for displaying a first OSD image; each storage node in the linked list is respectively used for storing the associated information of one OSD image block; determining at least one target OSD image block based on the associated information in the first storage node; generating the first OSD image based on each target OSD image block; and generating the picture based on the first OSD image, and displaying the picture. Therefore, the OSD image blocks are stored in a linked list mode, each OSD image block is independent and is not influenced by other OSD image blocks, and therefore the accuracy of the OSD image blocks is high; secondly, only the associated information of each OSD image block is stored in each storage node in the linked list, so that the storage space of the OSD image can be reduced, the associated information of the corresponding image block is only updated when the OSD image is updated, the firmware source code is not required to be modified, the updating complexity can be reduced, the repeatability and the convenience of the OSD image block can be improved, and the research and development difficulty and the research and development cost can be reduced; and thirdly, generating a picture based on the OSD image formed by the at least one OSD image block, so that the richness of the displayed picture can be improved, and the use experience of a user can be improved.

In some embodiments, the step S14 of "generating the screen based on the first OSD image" includes a step S141 of:

and step S141, aliasing the first OSD image and the image frame to be displayed to generate the picture.

Here, the image frame to be displayed may include, but is not limited to, a next video frame of a certain video, a currently displayed picture, and the like. For example, the first OSD image is aliased with the current display picture. For another example, the first OSD image is aliased with the first frame of the video to be played.

The aliasing algorithm may be any suitable algorithm that is capable of aliasing two images. Such as ALPHA aliasing algorithms, foreground overlay algorithms, background overlay algorithms, etc. In implementation, a person skilled in the art may autonomously determine an aliasing algorithm according to actual needs, and the embodiments of the present disclosure are not limited.

In the embodiment of the disclosure, the OSD image formed by at least one OSD image block and the image frame are subjected to aliasing to generate the picture, so that the richness of the displayed picture can be further improved, and the use experience of a user can be further improved.

In some embodiments, the step S141 includes steps S1411 to S1414, wherein:

step S1411, determining a first transparency of the first OSD image.

Here, the first transparency is a real number not greater than 1. The number of first transparencies may be at least one. Each transparency characterizes the transparency of a different region in the first OSD image. In some embodiments, the number of the first transparency is the same as the number of the target image blocks included in the first OSD image. For example, in the case that the first OSD image includes one target OSD image block, the number of the first transparency is one. For another example, in the case that the first OSD image includes at least two target OSD image blocks, the number of the first transparency is at least two. In implementation, the corresponding first transparency may be obtained based on the basic attribute information of the target OSD image block.

Step S1412, determining a first image based on the first OSD image and the first transparency.

Here, the manner of determining the first image may include, but is not limited to, a product of the first OSD image and the first transparency, a product of the first OSD image and the weighted first transparency, a product of the first OSD image and the second transparency, a product of the first OSD image and the weighted second transparency, and the like. Wherein the second transparency is based on the first transparency. For example, the second transparency may be a difference between the preset transparency and the first transparency, an inverse of the first transparency, and the like. In implementation, a person skilled in the art may autonomously determine the manner of the first image according to actual needs, and the embodiment of the disclosure is not limited.

In some embodiments, the first image DOUT1 may be obtained by the following equation (1-1), namely:

DOUT1＝DIN _osd *A _osd (1-1)；

in which DIN _osd Is a first OSD image, A _osd Is a first transparency, A _osd ∈[0,1]。

At A _osd At 0, the first image is completely transparent, i.e.: not displaying the first OSD image; at A _osd When not 0, the first image is not completely transparent, i.e.: and displaying the first OSD image.

Step S1413, determining a second image based on the image frame to be displayed and the first transparency.

Here, the manner of determining the second image may include, but is not limited to, a product of the image frame to be displayed and the first transparency, a product of the image frame to be displayed and the weighted first transparency, a product of the image frame to be displayed and the second transparency, a product of the image frame to be displayed and the weighted second transparency, and the like. Wherein the second transparency is based on the first transparency. For example, the second transparency may be a difference between the preset transparency and the first transparency, an inverse of the first transparency, and the like. In implementation, a person skilled in the art may autonomously determine the manner of the second image according to actual needs, and the embodiment of the disclosure is not limited.

In some embodiments, the first image DOUT2 may be obtained by the following equation (1-2), namely:

DOUT2＝DIN _original *(1-A _osd ) (1-2)；

therein, DIN _original For image frames to be displayed, A _osd Is a first transparency.

In A _osd At 1, the second image is completely transparent, i.e.: not displaying the image frame to be displayed; in A _osd When not 1, the image frame to be displayed is not completely transparent, that is: and displaying the image frame to be displayed.

Step S1414, aliasing the first image and the second image, and generating the picture.

Here, the manner of generating the screen may include, but is not limited to, the sum of the first image and the second image after being weighted, respectively, and the like. In implementation, a person skilled in the art may autonomously determine a manner of generating a picture according to actual requirements, and the embodiment of the present disclosure is not limited.

In some embodiments, the picture DOUT may be obtained by the following equations (1-3), namely:

DOUT＝DOUT1+DOUT2 (1-3)；

wherein, DOUT1 is the first image, and DOUT2 is the second image.

In the embodiment of the present disclosure, on the one hand, the transparency of the display of the first OSD image is achieved by the first transparency; on the other hand, the fusion of the first OSD image and the image frame to be displayed is realized by using the ALPHA aliasing, the richness of the displayed image is improved, and the use experience of the user can be improved.

In some embodiments, the method further comprises step S15, wherein:

step S15, responding to the received switching instruction, determining a target transparency matched with the switching instruction, and adjusting the transparency of the first OSD image to the target transparency.

Here, different switch instructions may correspond to the same or different target transparencies. The target transparency may be a real number not greater than 1. The generation mode of the switching instruction may include, but is not limited to, user operation generation, automatic generation by the electronic device, receiving an instruction sent by another device, and the like. The user operation may include, but is not limited to, a gesture, voice, body feeling, and the like. In implementation, a person skilled in the art may autonomously determine a generation manner of the switching instruction according to actual requirements, and the embodiment of the present disclosure is not limited. For example, a user executes a preset first operation gesture on the electronic device, and the transparency of the first OSD image is adjusted from a first transparency to 0; and the user executes a preset second operation gesture on the electronic equipment, and the transparency of the first OSD image is adjusted to 1 from the first transparency. For another example, when the electronic device detects that the resolution of the played video changes, such as: when the low frame frequency is switched to the high frequency frame, at this time, since the first OSD image may not be completely buffered, the transparency of the first OSD image may be adjusted from the first transparency to 0, and after the first OSD image is completely buffered, the transparency of the first OSD image is adjusted from 0 to the first transparency.

In the embodiment of the disclosure, a target transparency matching a switching instruction is determined in response to receiving the switching instruction, and the transparency of the first OSD image is adjusted to the target transparency. Therefore, the transparency of the first OSD image is adjusted, and the possibility of abnormal picture display can be reduced.

In some embodiments, the method further comprises steps S16 to S17, wherein:

and S16, responding to the received scaling instruction, and determining a scaling coefficient matched with the scaling instruction.

Here, different scaling instructions may correspond to different scaling factors. The zoom instruction may be generated by a user operation, automatically generated by the electronic device, or received from another device. The user operation may include, but is not limited to, a gesture, voice, body feeling, and the like. In implementation, a person skilled in the art may autonomously determine a generation manner of the zoom instruction according to actual requirements, and the embodiment of the present disclosure is not limited.

For example, a user performs a preset zooming gesture on the electronic device to generate the zooming instruction. For another example, the zoom instruction is generated when a change in resolution of the electronic device is detected.

In some implementations, the scaling factor may be generated based on a scaling instruction. For example, generated based on attributes of the user operation. The attribute of the operation may include, but is not limited to, type, distance, speed, location, duration, number, strength, etc. For example, different operation types correspond to different scaling factors. For another example, different numbers of clicks correspond to different scaling factors. For example, the scaling factor is calculated based on the step size of the sliding operation by the user. In implementation, a person skilled in the art may autonomously determine a generation manner of the scaling factor according to actual requirements, and the embodiment of the present disclosure is not limited. As another example, based on a change in resolution. For example, the ratio between the original resolution and the changed resolution is used as the scaling factor.

In some embodiments, the correspondence between the scaling instruction and the scaling factor may be established in advance and stored in the electronic device, or other electronic devices. And in the case that the corresponding relation is stored in the electronic equipment, the electronic equipment determines a scaling coefficient matched with the scaling instruction in the corresponding relation according to the scaling instruction. And under the condition that the corresponding relation is stored in other electronic equipment, the electronic equipment sends the scaling instruction to the other electronic equipment, so that the other electronic equipment determines the scaling coefficient matched with the scaling instruction in the corresponding relation according to the scaling instruction, and returns the scaling coefficient to the electronic equipment. In implementation, a person skilled in the art may autonomously determine the corresponding relationship between the scaling command and the scaling factor according to actual requirements, and the embodiment of the disclosure is not limited.

In some embodiments, the step S16 comprises a step S161 and/or a step S162, wherein:

step S161, in a case where the zoom instruction is a first zoom instruction, determining the zoom factor based on an original resolution and a changed resolution of the image frame to be displayed.

Here, the first zoom instruction characterization is automatically generated by the electronic device. The manner of determining the scaling factor may include, but is not limited to, a ratio between the original resolution and the changed resolution, a ratio after weighting the original resolution and the changed resolution, respectively, a difference between the original resolution and the changed resolution, a ratio between the original resolution/the changed resolution, and the like. In implementation, a person skilled in the art may autonomously select a manner of determining the scaling factor according to actual requirements, and the embodiment of the present disclosure is not limited.

In some embodiments, the scaling factor may be determined by the following equations (1-4):

where α is a scaling factor in the horizontal direction, β is a scaling factor in the vertical direction, X1, Y1 are a value of the original resolution in the horizontal direction and a value in the vertical direction, respectively, and X2, Y2 are a value of the changed resolution in the horizontal direction and a value in the vertical direction, respectively.

And step S162 of determining the scaling factor based on the second scaling instruction when the scaling instruction is the second scaling instruction.

Here, the second scaling command and the first scaling command are generated in different manners. In implementation, the second zooming instruction may be an instruction generated by a user operation or transmitted by another device.

Different second scaling instructions correspond to different scaling factors. In some embodiments, the scaling factor may be generated based on the second scaling instruction. For example, generated based on attributes of the user operation. The attribute of the operation may include, but is not limited to, type, distance, speed, location, duration, number, strength, etc. For example, different operation types correspond to different scaling factors. As another example, different click times correspond to different scaling factors. For example, the scaling factor is calculated based on the step size of the sliding operation by the user. In implementation, a person skilled in the art may autonomously determine a generation manner of the scaling factor according to actual requirements, and the embodiment of the present disclosure is not limited.

In some embodiments, the correspondence between the second scaling instruction and the scaling factor may be established in advance and stored in the electronic device, or in another electronic device. And under the condition that the corresponding relation is stored in the electronic equipment, the electronic equipment determines a scaling coefficient matched with the second scaling instruction in the corresponding relation according to the second scaling instruction. And under the condition that the corresponding relation is stored in other electronic equipment, the electronic equipment sends the second scaling instruction to the other electronic equipment, so that the other electronic equipment determines the scaling coefficient matched with the second scaling instruction in the corresponding relation according to the second scaling instruction, and returns the scaling coefficient to the electronic equipment. In implementation, a person skilled in the art may autonomously determine the corresponding relationship between the second scaling instruction and the scaling factor according to actual requirements, and the embodiment of the disclosure is not limited.

And S17, carrying out scaling processing on the first OSD image according to the scaling coefficient.

Here, the manner of the scaling process may include, but is not limited to, scaling the size, vertex coordinates, transparent region, non-transparent region, and the like of the first OSD image. For example, the size of the first OSD image is identical to the size of the display screen, and is 1920 × 1080, wherein the area containing the displayed content is a rectangular area formed by taking (50, 50) as the upper left corner and (100 ) as the lower right corner, in this case, the area is the non-transparent area, and the rest of the areas are transparent areas.

For example, the size of the first OSD image is scaled from a first size to a second size. For another example, the size of the non-transparent region of the first OSD image is scaled from a first size to a second size.

In some embodiments, the step S17 includes a step S171 and/or a step S172, wherein:

step S171, performing scaling processing on the target attribute of the first OSD image according to the scaling factor.

Here, the target attributes may include, but are not limited to, upper left corner coordinates, dimensions, lower right corner coordinates, and the like.

In some embodiments, the first OSD image may be scaled by the following equations (1-5):

U2＝αU1，V2＝βV1，Q2＝αQ1，P2＝βP1 (1-5)；

wherein, α is a zoom factor in the horizontal direction, β is a zoom factor in the vertical direction, U1 and V1 are width and height of the original size, Q1 and P1 are coordinate values of the original upper left corner, U2 and V2 are width and height of the zoomed size, and Q2 and P2 are coordinate values of the zoomed upper left corner.

And step S172, scaling the transparent region and the non-transparent region in the first OSD image according to the scaling factor.

Here, the size of the first OSD image may be identical to the display screen size, and the scaling of the first OSD image may be achieved by changing the ratio of the transparent area and the non-transparent area. For example, the first OSD image includes 4 OSD image blocks, where the transparency of the first OSD image block is not 0, and the transparencies of the remaining three OSD image blocks are 0. At this time, the OSD image blocks associated with the first OSD image block are respectively scaled according to the scaling coefficients, where the OSD image blocks associated with the first OSD image block may include the first OSD image block and an OSD image block adjacent to the first OSD image block.

Therefore, the size of each OSD image block forming the first OSD image does not need to be stored separately, the data structure of the OSD image blocks is simplified, and the data storage quantity is reduced.

In the embodiment of the disclosure, a scaling coefficient matched with a scaling instruction is determined by responding to the received scaling instruction; and carrying out scaling processing on the first OSD image according to the scaling coefficient. Therefore, only the first OSD image is zoomed according to the zoom coefficient, the data structure of the OSD image blocks forming the first OSD image does not need to be changed, the adaptability of the OSD image blocks is improved, and the research and development cost is reduced.

Fig. 2 is a schematic view of an implementation flow of a picture display method according to an embodiment of the present disclosure, as shown in fig. 2, the method includes steps S21 to S25, where:

step S21, responding to a display instruction for displaying a first OSD image, and determining a first storage node matched with the display instruction from at least one storage node in a preset linked list; each storage node in the linked list is respectively used for storing associated information of one OSD image block, and the associated information includes chain domain information and color information.

Here, the step S21 corresponds to the step S11, and in the implementation, reference may be made to a specific embodiment of the step S11.

Step S22, determining one target OSD image block based on the color information in the first storage node.

Here, the color information may include, but is not limited to, a color mapping table, a color index value, and the like. Each data in the color mapping table represents a color value of a pixel. Each color value can be composed of Y/R, G/Cb, B/Cr and ALPHA, wherein Y/R, G/Cb, B/Cr represent the basic color value of the pixel, and ALPHA represents the transparency of the pixel. In some embodiments, the color information may further include basic attribute information of the OSD image block. Basic attribute information may include, but is not limited to, size, position, transparency, color depth, and the like. In some implementations, the color depth can be determined based on an application scenario. For example, in a scene with high picture requirements, the color depth may be 256 color depths, such as an alarm. For another example, in a scene with low requirements on the picture, the color depth may be 16 color depths. In practice, the color depth may be determined based on preset rules. The preset rules may include, but are not limited to, default configuration of the electronic device, user customization, user preferences, frequency of use, user operation information, and the like. In implementation, a person skilled in the art may autonomously set the preset rule according to actual requirements, and the embodiment of the disclosure is not limited.

In some embodiments, the step S22 includes a step S221, in which:

step S221, based on the color index information in the first storage node, searching the color mapping table for color information matching the color index information, and using the color information as the color information of the target OSD image block.

Here, the number of color index information is related to the number of pixels of the OSD image block. Each pixel has a color index information. The number of color mapping tables is at least one. E.g., a color map of 256 color depths, a color map of 128 color depths, a color map of 16 color depths, etc. In implementation, a corresponding color mapping table may be determined based on the color depth in the first storage node, and based on the color mapping table, a color corresponding to the color index information may be looked up.

For example, for a 1920 × 1080 image, by using RGB true color storage, a 1920 × 1080 × 24bit (bit) storage space is required, and by using the color index information and the color mapping table, only a 1920 × 1080 × 8bit +256 × 24bit storage space is required, where 8bit is used to represent a color mapping table with a current color depth of 256, and for a color mapping table with a color depth of 128, 7bit is used, and 256 × 24bit represents RGB color information corresponding to each color depth.

In some embodiments, the color mapping table in the first storage node may be updated according to actual requirements. In practice, the colormap in the next first storage node is consistent with the colormap for that first storage node.

In some embodiments, the updating manner of the color mapping table may be selected based on a preset rule. The preset rules may include, but are not limited to, user customization, user preferences, frequency of use, user operation information, and the like. In implementation, a person skilled in the art may set the preset rule autonomously according to actual requirements, and the embodiment of the present disclosure is not limited.

For example, the electronic device provides a configuration option by which the user can import an existing colormap, or customize a desired colormap.

For another example, the updating manner may be determined based on attribute information of the user operation, where the attribute information may include, but is not limited to, a type, a distance, a speed, a location, a duration, a number of times, a strength, and the like of the operation. In implementation, a person skilled in the art may autonomously set a relationship between the attribute information of the operation and the update mode according to actual requirements, and the embodiment of the present disclosure is not limited. For example, when the user clicks on the electronic device, the color depth of the color mapping table is adjusted from the first color depth to the second color depth; the user adjusts the color depth of the color mapping table from the first color depth to a third color depth upon double-clicking on the electronic device. Wherein the first color depth, the second color depth, and the third color depth are different color depths.

Step S23, determining at least one target OSD image block based on the chain domain information in the first storage node when the chain domain information in the first storage node is not empty.

Here, the chain domain information at least includes address information characterizing at least one OSD image block associated with the OSD image. For example, for the double-chain table and the circular linked list, the chain domain information includes left chain domain information and right chain domain information, the right chain domain information includes address information of a next storage node associated with the first storage node, and the left chain domain information includes address information of a previous storage node associated with the first storage node. In some embodiments, the right-chain domain information may further include, but is not limited to, address information of the first storage node, basic attribute information of the image block, and the like.

In some embodiments, the chain domain information includes left chain domain information and right chain domain information, the left chain domain information includes address information of a last first storage node associated with the first storage node, and the right chain domain information includes address information of a next first storage node associated with the first storage node; the step S23 includes steps S231 to S232, in which:

Here, the successor node of the first storage node can be found from the linked list by the address information in the right-link domain information of the first storage node. At least one target OSD image block may be determined using the associated information in the subsequent node. In implementation, the manner of determining at least one target OSD image block based on the association information in the subsequent node is similar to the manner of determining at least one target OSD image block based on the association information in the first storage node in step S12, and in implementation, reference may be made to the specific implementation of step S12.

In some embodiments, the step S231 of determining at least one target OSD image block based on the address information in the right-chain domain information of the first storage node includes steps S2311 to S2313, where:

step S2311, a next first storage node is obtained based on the address information in the right-chain domain information of the first storage node.

Here, the successor node of the first storage node may be acquired from the linked list by the address information in the right-link domain information, and the successor node may be used as the next first storage node.

Step S2312, determining one target OSD image block based on the color information in the next first storage node.

Here, the manner of determining one target OSD image block is the same as the manner of determining one target OSD image block in step S22, and in implementation, reference may be made to the specific implementation of step S22.

Step S35, in response to receiving a generation instruction for a second OSD image, determining a configuration object associated with the second OSD image from the linked list.

Here, different generation instructions may correspond to the same or different configuration objects. The configuration object may be at least one storage node in a linked list. The second OSD image may be an existing OSD image or an additional OSD image. For example, the second OSD image may be the first OSD image or another OSD image.

In some embodiments, the generation instruction may include, but is not limited to, a modification instruction, an addition instruction, and the like.

The add instruction is used to add a storage node. The delete instruction is for deleting a storage node. The interchange instruction is used to exchange the location information of the two storage nodes. The adjustment instructions are used to modify the contents of a storage node. And the new instruction is used for adding a new instruction of the OSD image.

In some embodiments, the generation instruction may be determined according to an actual application scenario. In implementation, a person skilled in the art may independently select an obtaining manner of the generation instruction according to actual requirements, and the embodiment of the present disclosure is not limited. For example, the generation instruction is an instruction transmitted by the other device or the like. For another example, the generation instruction may be uploaded or set by the user through an input component of the electronic device on the operation interface. The input component may include, but is not limited to, a keyboard, a mouse, a touch screen, a touch pad, an audio input device, and the like. The operation interface comprises an interactive interface used for carrying out configuration operation and information display on the OSD images. The operation interface can be displayed on any suitable electronic equipment with interface interaction function. In practice, the electronic device displaying the operation interface may be the same as or different from the device executing the screen display method, and is not limited herein. For example, the electronic device executing the screen display method may be a notebook computer, the electronic device displaying the operation interface may also be the notebook computer, and the operation interface may be an interactive interface of a client running on the notebook computer, or a web page displayed in a browser running on the notebook computer. For another example, the electronic device executing the screen display method may be a server, the electronic device displaying the operation interface may be a notebook computer, the operation interface may be an interactive interface of a client running on the notebook computer, or a web page displayed in a browser running on the notebook computer, and the notebook computer may access the server through the client or the browser.

In some embodiments, the generation instructions further include configuration information for configuring the storage node. In implementation, different generation instructions correspond to different configuration information. For example, in the case where the generation instruction is an add instruction, the configuration information may be association information of a newly added storage node. For another example, in the case where the generation instruction is an interchange instruction, the configuration information may be location information of the storage node to be interchanged. For example, in the case where the generation instruction is an adjustment instruction, the configuration information may be changed contents.

And step S36, configuring the configuration object based on the configuration information in the generation instruction to generate the second OSD image.

Here, the configuration information is used for configuring the storage node. Different generation instructions correspond to different configuration information. Different generation instructions may correspond to the same or different configuration objects. For example, in the case where the generating instruction is a modify instruction, the configuration object may be a second storage node. The second storage node may be the first storage node, or may be another storage node. For another example, in the case that the generation instruction is a new instruction, the configuration object may be at least one storage node.

In some embodiments, in a case that the generation instruction is a modification instruction, the configuration object includes a second storage node, and the "configuring the configuration object based on the configuration information in the generation instruction" in step S36 includes at least one of step S361 to step S364, where:

step S361, when the modification instruction includes a delete instruction, acquiring a previous second storage node based on address information in the left-chain domain information of the second storage node; acquiring a next second storage node based on the address information in the right-chain domain information of the second storage node; and modifying the address information in the right-chain domain information of the last second storage node into the address information of the next second storage node, and modifying the address information in the left-chain domain information of the next second storage node into the address information of the last second storage node.

Here, the generation instruction is a deletion instruction, and the configuration information may be null at this time. For the double linked list, the address information of the right-chain domain of the predecessor node of the second storage node is modified into the address information of the successor node of the second storage node, and the address information of the left-chain domain of the successor node of the second storage node is modified into the address information of the predecessor node of the second storage node. For example, in fig. 1B, if the second storage node is the storage node 112, the address information 1080 of the right-chain domain of the storage node 111 is modified into the address information 1036 of the storage node 113, and the address information 1080 of the left-chain domain of the storage node 113 is modified into the address information 1050 of the storage node 111.

Step S362, under the condition that the modification instruction comprises an adding instruction, acquiring a third storage node based on the configuration information in the adding instruction; acquiring a fourth storage node based on the address information in the right-chain domain information of the second storage node; and modifying the address information in the right-chain domain information of the second storage node into the address information of the third storage node, modifying the address information in the left-chain domain information of the third storage node into the address information of the second storage node, modifying the address information in the right-chain domain information of the third storage node into the address information of the fourth storage node, and modifying the address information in the left-chain domain information of the fourth storage node into the address information of the third storage node.

Here, the generation instruction is an increase instruction, and the configuration information may be association information of an increased storage node. For the double-linked list, modifying the address information of the right-chain domain of the predecessor node of the second storage node into the address information of the third storage node, modifying the address information of the left-chain domain of the successor node of the second storage node into the address information of the third storage node, modifying the address information of the left-chain domain of the third storage node into the address information of the predecessor node of the second storage node, and modifying the address information of the right-chain domain of the third storage node into the address information of the successor node of the second storage node. For example, in fig. 1B, if the second storage node is the storage node 113 and the address information of the third storage node is 1200, then the fourth storage node is the storage node 114, the address information 1170 of the right-chain domain of the storage node 113 is modified to 1200, the address information 1036 of the left-chain domain of the storage node 114 is modified to 1200, the address information 1036 of the left-chain domain of the third storage node is modified to 1036, and the address information of the right-chain domain is modified to 1170.

Step S363, in a case that the modification instruction is an interchange instruction, acquiring a fifth storage node based on configuration information in the interchange instruction; acquiring a last second storage node based on the address information in the left chain domain information of the second storage node; acquiring a sixth storage node based on the address information in the right-chain domain information of the fifth storage node; and interchanging the address information in the left-chain domain information of the second storage node and the address information in the left-chain domain information of the fifth storage node, interchanging the address information in the right-chain domain information of the second storage node and the address information in the right-chain domain information of the fifth storage node, modifying the address information in the right-chain domain information of the last second storage node into the address information of the fifth storage node, and modifying the address information in the left-chain domain information of the sixth storage node into the address information of the fifth storage node.

Here, the generation instruction is an interchange instruction, and the configuration information may be address information of the storage node to be interchanged. For the double linked list, the link domain information of the second storage node and the link domain information of the fifth storage node are interchanged, the right link domain information of the predecessor node of the second storage node is modified into the address information of the fifth storage node, and the left link domain information of the successor node of the fifth storage node is modified into the address information of the second storage node. For example, in fig. 1B, if the second storage node is the storage node 112 and the fifth storage node is the storage node 114, at this time, the address information 1036 of the right-chain domain of the storage node 112 and the address information NULL of the right-chain domain of the storage node 114 may be interchanged, the address information 1050 of the left-chain domain of the storage node 112 and the address information 1036 of the left-chain domain of the storage node 114 may be interchanged, and the address information 1050 of the right-chain domain of the storage node 111 may be modified into the address information 1170 of the storage node 114.

Step S364, modifying the second storage node based on the configuration information in the adjustment instruction when the modification instruction is the adjustment instruction.

Here, the generation instruction is an adjustment instruction, and the configuration information may be content to be adjusted. For example, the association information in the second storage node is modified. Such as transparency, color depth, coordinates/size of the OSD image block, updating the color map table, etc.

In some embodiments, in a case that the generation instruction is a new instruction, the configuration object includes at least one seventh storage node; the step S36 includes a step S371 in which:

step S371, based on the configuration information in the new instruction, respectively configuring each seventh storage node.

Here, the generation instruction is a new addition instruction, and in this case, the configuration information may be associated information of at least one seventh storage node. In implementation, each seventh storage node may be sequentially added to the linked list according to the storage manner of the linked list. In some embodiments, the manner of adding the seventh storage node is similar to the manner of adding the third storage node in step S362, and in implementation, reference may be made to the detailed implementation of step S362.

In the embodiment of the disclosure, a first storage node matched with a display instruction is determined from at least one storage node in a preset linked list by responding to the display instruction for displaying a first OSD image; each storage node in the linked list is respectively used for storing the associated information of one OSD image block; determining at least one target OSD image block based on the associated information in the first storage node; generating the first OSD image based on each target OSD image block; generating the picture based on the first OSD image, and displaying the picture; in response to receiving a generation instruction of a second OSD image, determining a configuration object associated with the second OSD image from the linked list; and configuring the configuration object based on the configuration information in the generation instruction to generate the second OSD image. Therefore, firstly, each OSD image block is independently stored in a linked list mode, each OSD image block is independent and is not influenced by other OSD image blocks, and therefore the accuracy of the OSD image blocks is high; secondly, the change of the OSD image is realized by changing the chain domain information of the storage nodes, so that the change accuracy is improved, the update complexity is reduced, the requirements of different products and different manufacturers can be met, and the repeatability and the convenience of the OSD image can be improved; finally, the user can carry out autonomous configuration on the OSD image to be displayed, thereby improving the operation experience of the user.
