Technical Field

The present application relates to the field of information technology processing, and in particular, to a method and an apparatus for displaying a picture, and an electronic device.

Background

With the continuous development of the image processing technology field, the content on the picture can be provided to the display for display by the image processing device. In practical applications, the pictures may be stored in a storage device according to a specified path, and the storage device may be integrated in the image processing device or may be an independent device that can be accessed by the image processing device. When displaying a picture, the image processing device may read the picture from the specified path and then render the pixel points in the picture onto the display.

In order to highlight the selected target option and enhance the visual experience of the user, a picture corresponding to the selected target option may be dynamically displayed. As shown in fig. 1, an operation display interface of an Internet Protocol TV (IPTV) is taken as an example. The operation display interface can comprise a plurality of operation options, and a user can select one of the operation options through a remote controller to enter a corresponding program search list to order television programs. The operation option can be attached with a picture associated with the option theme, for example, the picture attached with the operation option "movie" can be a film roll frame. Typically, to prompt the user for a selected operation option, the selected operation option may be highlighted. Specifically, when the operation option "movie" is selected, the corresponding film roll frame picture can be dynamically changed, for example, the picture can be enlarged, translated, zoomed, and the like.

However, the existing method for highlighting the selected target option by dynamic picture change occupies a large space, which affects the efficiency of dynamic loading display of pictures. Specifically, the example of dynamically displaying the picture corresponding to the operation option in the above example is still taken as an example. A method may set multiple pictures for a target option, the multiple pictures requiring corresponding memory space. And after the target option is selected, the picture needs to be loaded into the system memory of the image processing equipment, the picture is released after the display is finished, and then the next picture also needs to be loaded into the system memory of the image processing equipment to execute the operations of the display release and the like. Therefore, the occupied system space is large, and the display efficiency of dynamic loading of pictures may be affected.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.

Please refer to fig. 2. One embodiment of the present application provides a picture display method, which may include the following steps.

Step S11: determining first boundary coordinates of a first pixel set, wherein the first pixel set comprises at least part of pixel point data of a preset picture stored in a first memory; wherein the first boundary coordinates define pixel point data contained by the first set of pixels.

In this embodiment, a pixel is the most basic unit constituting a picture. A picture can contain a plurality of pixel points, and the picture has different colors when displayed through different pixel point data. The pixel points in the picture are usually arranged in a matrix mode, so that each pixel point can have a coordinate in the pixel matrix, and the position of the pixel point can be identified by using the coordinate.

Since the size range processed by the image processing apparatus is [0, 1] in general, the size of the picture can be normalized. Specifically, when the picture is a rectangular picture, the sizes of the rectangular picture may be normalized by using the side lengths of two intersecting sides of the rectangular picture as references, so that the coordinate value of each pixel point in the rectangular picture may be limited to [0, 1 ].

Of course, the location of the pixel points may be identified in other ways. For example, the pixels are arranged in a matrix, and each pixel corresponds to an element of the matrix, which can be denoted as n_ij. And if i is the row where the pixel point is located and j is the column where the pixel point is located, the position of the pixel point can be uniquely identified through the row and the column.

In this embodiment, the first boundary coordinates of the first set of pixels may be defined in advance. I.e. the pixel data comprised in the first boundary coordinates form a first set of pixels. The content displayed by the pixel data included in the first pixel set is correspondingly a part of the content of the preset picture. The first boundary coordinates define a coordinate range, so that all pixel point data in the coordinate range in the preset picture can be determined, and a first pixel set is formed. The first boundary coordinates define that the first set of pixels contains pixel point data that may be such that coordinates of pixel point data included in the first set of pixels are within a range of coordinates defined by the first boundary coordinates. For example, the first boundary coordinates are (x1, y1), (x2, y2), where x1< x2, y1< y 2. The first boundary coordinate defines a coordinate range { (x, y) | x1 ≦ x2, and y1 ≦ y2}, and the set of all pixel point data in the coordinate range in the preset picture is taken as the first pixel set.

In this embodiment, the first memory may be a data storage device for storing information, which has a predetermined storage capacity. The first memory may be selected from a disk memory, an erasable programmable memory, a charged erasable programmable memory, and the like. Of course, only a partial listing of the type of first memory is provided herein, which may be a memory that retains data storage after power is removed. Other types of memories are also possible, as those skilled in the art will appreciate from the disclosure of the present application, and are intended to be within the scope of the present application so long as they perform the same or similar function and effect as the present application.

In this embodiment, the preset picture may be stored in the first memory according to a pre-specified path. The image processing device can read the pixel point data in the first boundary coordinate in the preset picture through the pre-specified path, so that the read pixel point data of the picture can be processed. Taking a television box as an example, a memory may be disposed in the television box, and the picture may be stored in the memory under a preset path, where the preset path may point to a preset folder in the memory, for example. When the television box starts to work, the television box can read pixel point data of the picture in the preset coordinate range from the preset path, namely pixel point data contained in the first pixel set, so that the pixel point data can be displayed on a display screen of the television.

Step S12: acquiring pixel point data of a first pixel set of the preset picture in the first memory according to the first boundary coordinates; and loading pixel point data included in the first pixel set acquired according to the first boundary coordinate into a second memory.

In the present embodiment, from the coordinate range defined by the first boundary coordinates, all the pixel point data within the coordinate range can be specified. The obtained pixel data may include coordinates and color values of the pixels. In this manner, after pixel point data is provided to the display screen, corresponding colors may be displayed at corresponding locations of the display screen according to a texture mapping algorithm.

In this embodiment, the second memory may be used to temporarily store data during picture processing by the processor of the image processing apparatus. Namely, the processor can perform data caching through the second memory in the process of rapidly processing the pixel data. The second memory may be selected from random access memory, cache memory, and the like. The second memory may have a smaller storage capacity than the first memory. The arrangement is such that a large amount of data can be stored by the first memory to maintain the integrity of the saved data. For example, the picture is stored in its entirety in the first memory. The read-write speed of the second memory can be higher than that of the first memory, so that the second memory can interact with the processor quickly, and the overall operation efficiency is improved.

In this embodiment, the pixel point data included in the first pixel set obtained according to the first boundary coordinate is loaded into the second memory, and the image processing program executed by the processor can process and operate the obtained pixel point data. As described above, in the prior art, to achieve the effect of displaying dynamic pictures, multiple pictures are loaded into the second storage, which occupies more memory capacity, and results in a decrease in the overall operating efficiency of the image processing apparatus. In the embodiment, only the pixel data corresponding to the part of the picture to be displayed finally is loaded into the second memory, that is, the pixel data to be displayed in the picture is loaded into the memory, so that the second memory is occupied as little as possible without affecting the overall function. Therefore, the occupation of resources is reduced, the processor can load other data into the second memory, and the data processing speed of the image processing device can be kept higher than that of the image processing device.

Step S13: and providing the pixel point data contained in the first pixel set for a display to display.

In this embodiment, the display may be a device including an I/O interface, a power supply, a driving module, and a display screen, and may convert the received pixel data into a picture through the I/O interface and display the picture on the display screen for a user to view.

In this embodiment, the image processing device may be connected to the display in a wired or wireless manner, and the image processing device may provide the pixel data included in the first pixel set to the display, so that the display may display the pixel on the display screen, and may further display a part of the content of the picture. In a specific application scenario, the tv box may be connected to a tv through a home lan, and the tv box may provide pixel data of a picture to the tv, so as to display the picture with corresponding content on a screen of the tv.

Step S14: calculating the first boundary coordinate according to a preset rule to obtain a second boundary coordinate of a second pixel set; wherein the second boundary coordinates define pixel point data contained by the second set of pixels.

In this embodiment, the second boundary coordinate may also define a coordinate range, so that all pixel point data in the preset picture in the coordinate range may be determined, and a second pixel set may be formed. The second boundary coordinates define that the pixel data comprised by the second set of pixels may be such that the coordinates of the pixels comprised in the second set of pixels are within the coordinate range defined by the second boundary coordinates.

In this embodiment, the calculating the first boundary coordinate according to the preset rule to obtain the second boundary coordinate may include: and performing incremental operation on the first boundary coordinates to obtain second boundary coordinates. For example, the first boundary coordinates are (x1, y1), (x2, y2), and the second boundary coordinates are (x1+ m1, y1+ n1), (x2+ m2, y2+ n2) assuming that the increment values of the abscissa and ordinate at which the first boundary coordinates are incremented are m1, n1, and m2, n2, respectively. The second boundary coordinate defines a coordinate range of { (x, y) | x1+ m1 ≦ x2+ m2, y1+ n1 ≦ y2+ n2}, and the set of all pixel point data in the coordinate range in the preset picture is taken as the second pixel set.

In the present embodiment, the increment values m1, n1, m2, and n2 for the increment operation of the first boundary coordinates may be positive values or negative values. The increment values of the first boundary coordinates may be equal or different. Different dynamic display effects can be obtained according to different increment values. For example, when the increment values of the horizontal and vertical coordinates of the first boundary coordinate are equal, that is, m1 is m2, and n1 is n2, the number of pixels included in the second pixel set may be equal to the number of pixels included in the first pixel set, and the corresponding dynamic effect may be panning. Alternatively, the abscissa and ordinate increment values m1 and n1 of the first boundary coordinates (x1 and y1) are negative values, and the abscissa and ordinate increment values m2 and n2 of the first boundary coordinates (x2 and y2) are positive values, so that the number of pixels included in the second pixel set is greater than the number of pixels included in the first pixel set, and the corresponding dynamic effect may be amplification. Alternatively, if the abscissa and ordinate increment values m1 and n1 of the first boundary coordinates (x1 and y1) are positive values and the abscissa and ordinate increment values m2 and n2 of the first boundary coordinates (x2 and y2) are negative values, the number of pixels included in the second pixel set is smaller than the number of pixels included in the first pixel set, and the corresponding dynamic effect may be a reduction.

Step S15: acquiring pixel point data of a second pixel set of the preset picture stored in the first memory according to the second boundary coordinate; wherein, the second pixel set comprises pixel data which is at least partially different from the pixel data of the first pixel set; and loading the acquired pixel point data included in the second pixel set into the second storage.

In the present embodiment, from the coordinate range defined by the second boundary coordinates, all the pixel point data within the coordinate range can be specified. The obtained pixel data may include coordinates and color values of the pixels. In this manner, after pixel point data is provided to the display screen, corresponding colors may be displayed at corresponding locations of the display screen according to a texture mapping algorithm.

In this embodiment, the difference between at least a portion of the pixel data included in the first pixel set and the pixel data included in the second pixel set may be: the pixel point data contained in the first pixel set is partially the same as the pixel point data contained in the second pixel set, and partially different. For example, a first set of pixels defined by the first boundary coordinates and a second set of pixels defined by the second boundary coordinates contain common pixel data. Specifically, the following relationship exists between the first boundary coordinates and the second boundary coordinates: x1+ m1< x2, y1+ n1< y 2. Then the pixel data with the coordinate in { (x, y) | x1+ m1 ≦ x2, and y1+ n1 ≦ y2} in the picture are common to the two pixel sets, and the part of the pixel data is the same part of the two pixel sets. The difference between at least part of the pixel data contained in the first pixel set and the pixel data contained in the second pixel set can be as follows: the pixel point contained in the first pixel set is completely different from the pixel point data contained in the second pixel set. That is, the pixels contained in the first pixel set are different from the pixels contained in the second pixel set. Specifically, the following relationship exists between the first boundary coordinates and the second boundary coordinates: x1+ m1> x2, y1+ n1> y 2. And then the first boundary coordinate and the second boundary coordinate do not have intersection, so that the pixel point data in the two pixel sets are completely different.

In this embodiment, the pixel data included in the second pixel set is at least partially different from the pixel data included in the first pixel set, so that when the pixel included in the second pixel set is displayed on the screen of the display in place of the pixel included in the first pixel set, the picture displayed on the screen of the display can display a dynamic change effect.

Step S16: and providing the pixel point data contained in the second pixel set to the display for displaying.

In this embodiment, the image processing device may provide the pixel data included in the second pixel set to the display, so that the display may display the pixel on the display screen, and may further display the content of another part of the preset picture.

According to the picture display method, the first pixel set and the second pixel set which contain at least partially different pixel point data are provided for the display to be displayed, so that the picture content displayed by the display can be switched from the first pixel set to the second pixel set, and the purpose of displaying the dynamic picture is achieved. In the process, the picture is not required to be loaded into the second memory in a whole manner, and only the pixel point data which needs to be displayed on the display is loaded into the second memory, so that the occupation of the second memory is reduced, and the data processing efficiency is improved in a whole manner.

In a specific application scenario, a television box can be used to control to dynamically display a picture corresponding to an operation option of an operation display interface of the interactive network television on a display screen of the television. Specifically, when one operation option is selected, the television box may obtain a first pixel set, which is a pixel point included in a part of the region of the picture corresponding to the operation option, and may load the part of the pixel point data into the system space for processing, and then the television box may provide the pixel point data included in the first pixel set to a television connected to the television in a wired or wireless manner, so that the content of the first pixel set may be displayed on a display screen of the television. Specifically, the obtaining of the pixel data included in the first pixel set may be implemented by a pixel Shader (Fragment Shader) built in a graphics card of the television box. After the display of the pixel points in the first pixel set is completed for a predetermined time, for example, 1s, the television box may obtain pixel point data included in another part of the area of the picture, that is, a second pixel set, and may load the part of the pixel point data into a system space for processing, and then the television box may provide the pixel point data included in the second pixel set to a television connected thereto in a wired or wireless manner, so that the content of the second pixel set may be displayed on a display screen of the television. The second pixel set and the first pixel set are different in at least part of pixel point data, and when a picture displayed on a display screen is switched from the content of the first pixel set to the content of the second pixel set, the purpose of displaying a dynamic picture is achieved. And according to the difference of the coordinates of the pixel points contained in the two pixel sets, dynamic effects such as amplification, translation, scaling and the like can be generated. In the process, the television box does not need to load the whole picture into the system space, but only loads the pixel data to be displayed on the television into the system space, so that the occupation of the system space is reduced, and the data processing efficiency of the television box is improved on the whole.

In one embodiment, the first boundary coordinate may include two pixel coordinates, and an abscissa and an ordinate of the two pixel coordinates are different from each other. The abscissa and the ordinate of the two pixel points form the first boundary coordinate together.

In this embodiment, the first boundary coordinates may include two pixel coordinates, for example, the two pixel coordinates may be (x1, y1), (x2, y 2). The abscissa and the ordinate of the two pixel point coordinates are different, namely x1 is not equal to x2, and y1 is not equal to y 2. Therefore, a space with a certain numerical range can be limited, the pixel point of which the coordinate is located in the first boundary coordinate can finally show a picture with the size not being zero in the horizontal and vertical directions of the two-dimensional space, and the pixel point of which the coordinate is located between the first boundary coordinates is prevented from being finally displayed as a straight line.

In this embodiment, the horizontal and vertical coordinates of the two pixels can be crossed to obtain another two coordinates, so that the first boundary coordinate is formed according to the horizontal and vertical coordinates of the two pixels. Specifically, the two pixel coordinates are (x1, y1), (x2, y2), and the other two coordinates obtained by intersecting are (x1, y2), (x2, y 1). The pixel points included in the first pixel set determined by the embodiment are mapped to the screen of the display, so that a rectangular picture can be obtained. The rectangular picture is a part of the preset picture.

Certainly, in the application, the pixel points in the first pixel set are mapped to the screen of the display, and the obtained picture is not limited to a rectangular picture, and pictures with other shapes can also be obtained. In one embodiment, the pixels contained within the first set of pixels are distributed around at least one of the pixels. The first boundary coordinate is a preset function of the coordinate of the at least one surrounded pixel point as a parameter.

In this embodiment, the coordinates of the at least one pixel point are also located in the first boundary coordinates, the pixel points included in the first pixel set are distributed around the at least one pixel point, and the first boundary coordinates are preset functions using the coordinates of the at least one pixel point as parameters, so that a plurality of different first boundary coordinates conforming to the preset functions can be obtained according to different preset functions, and thus, when the pixel points included in the first pixel set defined according to the first boundary coordinates are mapped onto the screen of the display, pictures with different shapes can be correspondingly displayed.

For example, a distance between a pixel point included in the first boundary coordinates and one of the at least one pixel point is not greater than a first threshold. Specifically, the coordinates of one pixel point of the at least one pixel point are (a, b), the first threshold value is c, and the first boundary coordinates are (x, y). The first boundary coordinate has a predetermined function of (x-a) using the coordinate of one of the at least one pixel as a parameter²+(y-b)²≤c². Thus, when the pixel points included in the first pixel set defined according to the first boundary coordinate are mapped to the screen of the display, a circular picture can be obtained, the center of the circle of the circular picture is one of the at least one pixel point, and the radius of the circular picture is the first threshold value.

For another example, a sum of distances between a pixel point included in the first boundary coordinate and two pixel points of the at least one pixel point is not greater than a second threshold. Specifically, the coordinates of two of the at least one pixel are (a, b), (c, d), the second threshold is e, the first boundary coordinate is (x, y), and the preset function of the first boundary coordinate using the coordinates of two of the at least one pixel as parameters is [ (x-a)²+(y-b)²]^0.5+[(x-c)²+(y-d)²]^_.05E is less than or equal to e. Thus, will sit according to the first boundaryWhen the pixels contained in the first pixel set defined by the mark are mapped to the screen of the display, an elliptical picture can be obtained, the focus of the elliptical picture is two pixels in the at least one pixel, and the focus is the distance between the two pixels in the at least one pixel.

Please refer to fig. 3. An embodiment of the present application provides an apparatus 100 for displaying a picture, where the apparatus 100 may include a first boundary coordinate determination module 11, a first pixel point data obtaining module 12, a first pixel point data providing module 13, a second boundary coordinate determination module 14, a second pixel point data obtaining module 15, and a second pixel point data providing module 16.

Of course, the location of the pixel points may be identified in other ways. For example, the pixels are arranged in a matrix, and each pixel corresponds to an element of the matrix, which can be denoted as n_ij. Wherein i is the row where the pixel point is locatedAnd j is a column where the pixel point is located, the position of the pixel point can be uniquely identified through the row and the column.

In the process, the picture is not required to be loaded into the second memory in a whole manner, and only the pixel point data which needs to be displayed on the display is loaded into the second memory, so that the occupation of the second memory is reduced, and the data processing efficiency is improved in a whole manner.

Please refer to fig. 4. An embodiment of the present application further provides an electronic device 200, where the electronic device 200 may include: communication terminal 21, processor 24, first memory 22, second memory 23.

The communication terminal 21 can perform network data transmission according to a predetermined encoding rule. Specifically, the communication terminal 21 may be designed and manufactured according to protocols such as Http, TCP/IP, and the like. In this way, the communication terminal 21 can perform network data transmission in accordance with protocols such as Http, TCP/IP, and the like.

The first memory 22 stores pictures.

The processor 24 is capable of controlling, upon reading the picture from the first storage 22 through the communication terminal 21, determination of first boundary coordinates of a first set of pixels including at least part of pixel point data of the picture stored in the first storage 22; wherein the first boundary coordinates define pixel point data contained by the first set of pixels.

And controlling the data of the pixel points contained in the second pixel set to be provided for the display to display.

Please refer to fig. 5. One embodiment of the present application provides a picture display method, which may include the following steps.

Step S31: determining first boundary coordinates of a first pixel set, wherein the first pixel set comprises at least part of pixel point data of a preset picture stored in a first memory; wherein the first boundary coordinates define pixel point data contained by the first set of pixels.

Of course, the location of the pixel points may be identified in other ways. For example, the pixels are arranged in a matrix, and each pixel corresponds to an element of the matrix, which can be denoted as nij. And if i is the row where the pixel point is located and j is the column where the pixel point is located, the position of the pixel point can be uniquely identified through the row and the column.

In this embodiment, the preset picture may be stored in the first memory according to a pre-specified path. The image processing device can read the pixel point data in the first boundary coordinate in the preset picture through the pre-specified path, so that the read pixel point data of the picture can be processed. Taking a television with an image processing device built in as an example, a memory may be provided in the image processing device, in which a picture may be stored under a preset path, which may point to a preset folder in the memory, for example. When the image processing device starts working, the image processing device can read the pixel point data of the picture in the preset coordinate range from the preset path, so that the pixel point data can be displayed on the display screen of the television.

Step S32: acquiring pixel point data of a first pixel set of the preset picture in the first memory according to the first boundary coordinates; and loading pixel point data included in the first pixel set acquired according to the first boundary coordinate into a second memory.

In this embodiment, the second memory may be used to temporarily store data during picture processing by the image processing apparatus. Namely, the processor can perform data caching through the second memory in the process of rapidly processing the pixel data. The second memory may be selected from random access memory, cache memory, and the like. The second memory may have a smaller storage capacity than the first memory. The arrangement is such that a large amount of data can be stored by the first memory to maintain the integrity of the saved data. For example, the picture is stored in its entirety in the first memory. The read-write speed of the second memory can be higher than that of the first memory, so that the second memory can interact with the processor quickly, and the overall operation efficiency is improved.

In this embodiment, the pixel point data included in the first pixel set obtained according to the first boundary coordinate is loaded into the second memory, and the image processing program executed by the processor can process and operate the obtained pixel point data. As described above, in the prior art, to achieve the effect of displaying dynamic pictures, multiple pictures are loaded into the second storage, which occupies more memory capacity, and results in a decrease in the overall operating efficiency of the image processing apparatus. In the embodiment, only the pixel data corresponding to the part of the picture to be displayed finally is loaded into the second memory, that is, the pixel data to be displayed in the picture is loaded into the memory, so that the second memory is occupied as little as possible without affecting the overall function. Therefore, the resource occupation is reduced, the processor can load other data into the second memory, and the data processing speed of the image processing device can be kept higher than that of the image processing device.

Step S33: and displaying pixel point data contained in the first pixel set in a predetermined area of a display screen.

In this embodiment, the display screen can be used to display images and colors. The display principles of different kinds of display screens are different. Taking a Liquid Crystal Display (LCD) screen as an example, the principle is that under the action of an electric field, the arrangement direction of Liquid Crystal molecules is changed to change the light transmittance of an external light source to complete electro-optical conversion, and then the reproduction of pictures and colors on the Display screen is realized by the excitation of RGB three-primary-color signals.

In this embodiment, the predetermined area may be used to display the pixel points included in the first pixel set, and may occupy a part of the display screen or the entire display screen. In a specific application scenario, taking an operation display interface of an Internet Protocol Television (IPTV) as an example, the entire operation display interface is displayed on a display screen of a television, and an area corresponding to each operation option is the predetermined area.

Step S34: calculating the first boundary coordinate according to a preset rule to obtain a second boundary coordinate of a second pixel set; wherein the second boundary coordinates define pixel point data contained by the second set of pixels.

Step S35: acquiring pixel point data of a second pixel set of the preset picture stored in the first memory according to the second boundary coordinate; wherein, the second pixel set comprises pixel data which is at least partially different from the pixel data of the first pixel set; and loading the acquired pixel point data included in the second pixel set into the second memory.

Step S36: and displaying pixel point data contained in the second pixel set in the predetermined area of the display screen.

In this embodiment, the pixel points included in the second pixel domain may be provided to the display, so that the pixel points are displayed in a predetermined area on the display screen of the display, and the content of another part of the picture may be displayed.

According to the picture display method, the first pixel set and the second pixel set which are at least partially different in pixel point data are displayed in the preset area of the display screen, so that the picture content displayed on the display screen can be switched from the first pixel set to the second pixel set, and the purpose of displaying the dynamic picture is achieved. In the process, the picture is not required to be loaded into the second memory in a whole manner, and only the pixel point data which needs to be displayed on the display is loaded into the second memory, so that the occupation of the second memory is reduced, and the data processing efficiency is improved in a whole manner.

In a specific application scenario, the image processing device built in the television can be used to control to dynamically display the picture corresponding to the operation option of the operation display interface of the interactive network television on the display screen of the television. Specifically, when a certain operation option is selected, the image processing device may obtain a first pixel set, which is a pixel point included in a part of regions of the picture corresponding to the operation option, and may load the part of pixel point data into the system space for processing, and then the image processing device may display the pixel point included in the first pixel region on the region corresponding to the operation option of the operation display interface. Specifically, the obtaining of the color of the pixel point included in the first pixel domain may be implemented by a pixel Shader (Fragment Shader) built in a graphics card of the image processing device. After the display of the pixel point in the first pixel domain for a predetermined time period, for example, 1s, is completed, the image processing device may obtain pixel point data, that is, a second pixel set, included in another part of the region of the picture, and may load the part of the pixel point data into the system space for processing, and then the image processing device may display the pixel point data included in the second pixel domain on the region corresponding to the operation option of the operation display interface. And when the picture displayed on the area corresponding to the operation option of the operation display interface is switched from the content of the first pixel domain to the content of the second pixel domain, the aim of displaying the dynamic picture is fulfilled. And according to the difference of the positions of the first pixel domain and the second pixel domain in the picture, dynamic effects such as amplification, translation, scaling and the like can be generated. In the process, the image processing device of the television does not need to load the whole picture into the system space, but only loads the pixel point data which needs to be displayed on the television into the system space of the image processing device of the television, so that the occupation of the system space is reduced, and the data processing efficiency of the television with the built-in image processing device is improved on the whole.

For example, the pixel point contained in the first boundary coordinate and the at least oneThe distance between one of the pixel points is not greater than a first threshold. Specifically, the coordinates of one pixel point of the at least one pixel point are (a, b), the first threshold value is c, and the first boundary coordinates are (x, y). The first boundary coordinate has a predetermined function of (x-a) using the coordinate of one of the at least one pixel as a parameter²+(y-b)²≤c². Thus, when the pixel points included in the first pixel set defined according to the first boundary coordinate are mapped to the screen of the display, a circular picture can be obtained, the center of the circle of the circular picture is one of the at least one pixel point, and the radius of the circular picture is the first threshold value.

For another example, a sum of distances between a pixel point included in the first boundary coordinate and two pixel points of the at least one pixel point is not greater than a second threshold. Specifically, the coordinates of two of the at least one pixel are (a, b), (c, d), the second threshold is e, the first boundary coordinate is (x, y), and the preset function of the first boundary coordinate using the coordinates of two of the at least one pixel as parameters is [ (x-a)²+(y-b)²]^_.05+[(x-c⁾²+(y-d)²]^_.05E is less than or equal to e. Thus, when the pixel points contained in the first pixel set defined according to the first boundary coordinate are mapped to the screen of the display, an elliptical picture can be obtained, the focus of the elliptical picture is two pixel points in the at least one pixel point, and the focal distance is the distance between the two pixel points in the at least one pixel point.

In the process, the picture is not required to be loaded into the second memory in a whole manner, and only the pixel point data which needs to be displayed on the display is loaded into the second memory, so that the occupation of the second memory is reduced, and the data processing efficiency is improved in a whole manner.

It should be noted that, in the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no precedence between the two is intended or should be construed to indicate or imply relative importance. In addition, in the description of the present application, "a plurality" means two or more unless otherwise specified.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

For convenience of description, the above devices are described as being divided into various modules by functions, and are described separately. Of course, the functionality of the various modules may be implemented in the same one or more software and/or hardware implementations as the present application.
