[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a method for implementing an irregular layer. The heteromorphic layer implementation method can be applied to video processing devices such as card-insertion type switchers, video processors, video converters and the like. Specifically, the method for implementing the special-shaped layer provided by the embodiment of the present invention includes, for example, the steps of:

Specifically, the transparency data of the target special-shaped template includes first transparency data of the target special-shaped effective area and second transparency data of the target special-shaped ineffective area, the first transparency data is incompletely transparent data, and the second transparency data is completely transparent data; the layer information of the first layer includes a resolution of the first layer. Typically, the resolution of the first image layer may be represented by, for example, the width x height of the first image layer.
Further, as shown in fig. 2A, step S11 includes, for example:
s111: receiving the transparency data of the special-shaped template through a master control circuit and storing the transparency data into a volatile memory; and
s113: reading the transparency data of the shaped template from the volatile memory.
Therefore, the transparency data of the special-shaped template can be stored in the volatile memory so that other scaling processing channels can also use the transparency data of the special-shaped template to realize special-shaped display, and the layer processing capacity and the layer display effect of the video processing device are further improved.
As shown in fig. 2B, step S17 includes, for example:

Namely, the first transparency data and the second transparency data in the target special-shaped template are respectively assigned to the first area and the second area corresponding to the first image layer, so that the special-shaped image layer with the special-shaped effect is formed.
In addition, as shown in fig. 3, the method for implementing the special-shaped layer further includes:
s18: acquiring a second image layer;
s19: and overlapping the second image layer and the special-shaped image layer.
Therefore, the special-shaped layer can be displayed on the second layer, and the application of the special-shaped effect is realized.
In order to facilitate understanding of the present invention, the following describes in detail each step of the method for implementing the profiled layer according to the embodiment of the present invention with reference to fig. 4A to 4D.
The method for realizing the special-shaped layer provided by the embodiment of the invention can be applied to video processing equipment to realize special-shaped processing of the layer. The video processing device here may be connected, for example, to a display screen or other display system such as a display controller and display control card and a display screen. The display screen may be, for example, an LED display screen, or may also be other display screens such as an LCD or other types of display screens, which is not limited in the present invention. Typically, the video processing device herein may be, for example, an electronic device having processing capabilities for performing a morphing process, an overlay process, and the like on a layer.
As shown in fig. 4A, the video processing apparatus 100 includes, for example, a main control circuit 110, a programmable logic device 120, an image output interface 130, and a volatile memory 140. The main control circuit 110 is connected to the programmable logic device 120, and the programmable logic device 120 is further connected to the image output interface 130 and the volatile memory 140. The master control circuit 110 may, for example, include a processor, such as an MCU (Microcontroller Unit), an ARM, or the like, which is mainly used for loading an FPGA program, transceiving control instructions, communicating with other devices, such as an upper computer, and the like. The Programmable logic device 120 is, for example, an FPGA (Field Programmable Gate Array), and is configured to obtain a special-shaped template including transparency data, and a first layer and a second layer that are externally input, and process the first layer according to the transparency data of the special-shaped template, for example, perform transparency processing on the first layer to obtain a special-shaped layer. And further, overlapping the special-shaped layer and the received second layer, and outputting the overlapped layer through an image output interface for display. It should be noted here that the special-shaped template is, for example, a document including transparency data of pixel points, and may also exist in a form, a list, an image, or other forms. The size of the transparency data represents the transparency of the pixel points, and the transparency data is a component parameter Alpha (a for short) representing the transparency of the color data of the pixel points of the image layer.
As mentioned above, the image output interface 130 may be, for example, a standard video output interface, such as an HDMI interface, a DVI interface, or the like. The number of the image output interfaces 130 may be one or more, for example. The volatile memory 140 is, for example, a DDR (Double Data Rate SDRAM), and is mainly used for buffering Data and information during the operation of the video processing apparatus, for example, transparency Data of the special-shaped template transmitted via the main control circuit 110 received by the programmable logic device 120, and buffered Data during the scaling and overlay processes of the programmable logic device 120.
The method for realizing the special-shaped layer provided by the embodiment of the invention mainly obtains the special-shaped layer with the special-shaped display effect by obtaining the transparency data of the special-shaped template and performing transparency processing on the first layer according to the transparency data of the special-shaped template, thereby solving the problems that a multimedia video server is required to realize the special-shaped layer in the prior art, being convenient and fast, having higher flexibility, reducing the equipment cost, and further improving the image processing capability and the display effect of video processing equipment.
As shown in fig. 4A, the main control circuit 110 of the video processing device 100 receives an externally input special-shaped template and transparency data thereof, and transmits the special-shaped template and the transparency data to the programmable logic device 120, and the programmable logic device 120 receives the transparency data of the special-shaped template via the main control circuit 110 and stores the transparency data in the volatile memory 140; the transparency data of the shaped template is read from the volatile memory 140 when it is desired to use the transparency data of the shaped template. Therefore, when a plurality of layer processes generally require special-shaped processes (or transparency processes), the transparency data of the special-shaped template can be read from the volatile memory 140 for processing without mutual influence, and the layer processing efficiency and capacity of the device and the layer display effect are improved.
Programmable logic device 120 obtains the first layer, for example, by receiving an external input source. The first layer here is, for example, a special-shaped layer obtained by performing transparency processing according to transparency data of a special-shaped template.
Next, the programmable logic device 120 reads the transparency data of the shaped template from the volatile memory 140. Specifically, as shown in fig. 4B, the shaped template includes, for example, a shaped effective area (white area in fig. 4B) and a shaped ineffective area (black area in fig. 4B). The special-shaped effective area is an area where a display needs to be reserved, and the special-shaped effective area can be a diamond shape, an oval shape, a circular shape, a star shape, a triangular shape, a crescent shape, a pentagonal shape and the like. The shaped inactive area may be, for example, an area that does not need to be displayed, that is, an area other than the shaped active area.
Further, after reading the transparency data of the special-shaped template, the programmable logic device 120 may further perform scaling processing on the special-shaped template according to the layer information of the first layer, for example, the resolution of the first layer, to obtain the target special-shaped template, so that the target special-shaped template reaches a desired size. The target shaped template also includes, for example, a target shaped active area corresponding to the shaped active area and a target shaped inactive area corresponding to the shaped inactive area. The target shaped active area may also be, for example, diamond, oval, circular, star, triangle, crescent, pentagon, etc. The target shaped inactive area may be illustrated as an area on the target shaped template outside the target shaped active area. When the size of the target special-shaped template is the same, namely the scaling processing proportion is 1, the size of the target special-shaped effective area is the same as that of the special-shaped effective area; when the sizes of the target special-shaped templates are different, namely the scaling processing proportion is not 1, the sizes of the target special-shaped effective area and the special-shaped effective area are different. The target shaped active area and the target shaped inactive area each have transparency data, e.g. the target shaped active area comprises first transparency data and the target shaped inactive area comprises second transparency data. Further, the first transparency data of the target special-shaped effective area is non-completely transparent data, and the second transparency data of the target special-shaped ineffective area is completely transparent data. The value range of the transparency data here may be, for example, [0,1], where the value of the completely transparent data is 0, which indicates that the pixel point is completely transparent and is not displayed. The value of the completely opaque data is 1, the pixel point is represented, the completely opaque data is completely opaque, and the pixel point below the completely opaque data is completely shielded by the pixel point and cannot be seen. The value range of the non-completely transparent data is greater than 0 and less than or equal to 1 (that is, 0 is not included), which indicates that the pixel point may be completely opaque or partially transparent. Of course, for the convenience of system calculation, the value of the transparency data is fixed from [0,1] to [0,128], where 0 represents that the transparency data is completely transparent and 128 represents that the transparency data is completely opaque. Of course, the present invention may be fixed to other value ranges, and the present invention is not limited thereto.
Then, the programmable logic device 120 performs transparency processing (or referred to as morphing processing) on the first layer according to the transparency data of the target morphic template to obtain a morphic layer, which may also be referred to as target morphic template stacking, that is, stacking the target morphic template on the first layer. Specifically, the programmable logic device 120 assigns the first transparency data to transparency data of a first region corresponding to the target special-shaped effective region on the first layer, and assigns the second transparency data to transparency data of a second region corresponding to the target special-shaped ineffective region on the first layer. That is, the programmable logic device 120 assigns the transparency data in the target special-shaped template to the transparency component of the corresponding pixel point on the first layer to obtain the special-shaped layer, so that the data of each pixel point of the special-shaped layer includes data of four components, for example, ARGB data, that is, transparency data a, red component data R, green component data G, and blue component data B. When the transparency data A is completely transparent data, the pixel point is in a completely transparent state; when the transparency data a is completely opaque data, the pixel point is in a completely opaque state, so that the special-shaped layer shown in fig. 4C is obtained, that is, the pixel point corresponding to the special-shaped effective area on the special-shaped layer is visible, and the pixel point corresponding to the special-shaped ineffective area on the special-shaped layer is invisible. In addition, as shown in fig. 4C, the image data of the rhombus-shaped special-shaped image layer includes not only the image data of the diamond-shaped region (i.e., the special-shaped effective region), but also the actual image data is still the rectangular image data having the same size as the first image layer before transparency processing, except that the transparency data a of the pixels in the non-diamond-shaped region (i.e., the special-shaped ineffective region) is 0, i.e., is completely transparent and invisible.
In addition, as shown in fig. 4D, programmable logic device 120 obtains a second layer. The second layer is, for example, a layer that is subjected to overlay processing with the heteromorphic layer. The second layer may be, for example, other conventional layers, or may be a background picture. Then, the programmable logic device 120 superimposes the special-shaped layer and the second layer.
Specifically, when the layer superposition is performed, the input layer data of the special-shaped layer is in an ARGB format, where a represents transparency data. When the ARGB layer data needs to be superimposed on the second layer, a calculation formula (1) of the image data of the superimposed image before layer data localization of the special-shaped layer is as follows:
R'＝A×R1+(1-A)×R0
G'＝A×G1+(1-A)×G0
B'＝A×B1+(1-A)×B0，
wherein (R)0，G0，B0) Image data representing pixel points on the second layer, and (A, R)1，G1，B1) And (R ', G ', B ') representing the image data of the superposed image.
After the layer data of the special-shaped layer is fixed, the calculation formula (2) of the image data of the superposed image is as follows:
Figure BDA0002726323790000101
Figure BDA0002726323790000102
Figure BDA0002726323790000103
when the layers are superposed and calculated, the transparency data A of each pixel point of the second layer21-a. When the transparency data A of the pixel points of the special-shaped layer is equal to 0, the transparency data A of the corresponding pixel points on the second layer21, i.e. completely opaque, i.e. the display is visible. When the transparency data A of the pixel points of the special-shaped layer is equal to 1, the transparency data A of the corresponding pixel points on the second layer20, i.e. completely transparent, i.e. the display is not visible. Therefore, after the superposition processing, the special-shaped display effect is superposed on the second image layer, that is, the rhombus is displayed on the second image layerThe shaped active area of (2).
In addition, referring to fig. 4E, before the special-shaped layer and the second layer are superimposed, layer scaling processing may be performed on the special-shaped layer, so that the size of the special-shaped layer is the same as that of the second layer, and thus, layer superimposition is performed better. The scaling process here can be the same as the aforementioned scaling process, and certainly can also be implemented by using the scaling process method in the prior art, which is not described here again.
Further, as shown in fig. 4F, a special-shaped transparency data template may also be obtained on the second layer to achieve a second special-shaped effect, and the specific implementation process is generally as follows: obtaining a special-shaped template M and a special-shaped template N for the first image layer and the second image layer in a one-to-one correspondence mode, then performing transparency processing on the first image layer and the second image layer respectively by adopting the method to obtain a first special-shaped image layer and a second special-shaped image layer, and finally performing image layer superposition processing on the first special-shaped image layer and the second special-shaped image layer to obtain a superposed image. Therefore, a plurality of special-shaped display effects can be realized under the condition of occupying the least system resources, and the processing capacity and the display effect of the equipment are further improved.
In summary, the embodiment of the present invention obtains the processed special-shaped layer by obtaining the transparency data of the special-shaped template and performing transparency processing on the first layer according to the transparency data, so as to solve the problem that a multimedia video server is required to implement the special-shaped layer in the prior art, which is convenient, fast and highly flexible, reduce the equipment cost, and further improve the image processing capability and the display effect of the video processing equipment.

[ third embodiment ]
As shown in fig. 6, a third embodiment of the present invention provides a method for implementing an irregular layer. The heteromorphic layer implementation method can be applied to video processing devices such as card-insertion type switchers, video processors, video converters and the like. Specifically, the method for implementing the special-shaped layer provided by the embodiment of the present invention includes, for example, the steps of:
s21: acquiring a first layer comprising pixel points with preset display parameter data;
s23: and performing transparency processing on the first image layer according to the preset display parameter data to obtain a special-shaped image layer.
Therefore, the special-shaped layer is obtained by performing transparency processing on the first layer according to the preset display parameter data, the problem that the special-shaped layer is needed to be realized by using a multimedia video server in the prior art is solved, convenience, rapidness and higher flexibility are achieved, the equipment cost is reduced, and the image processing capacity and the display effect of the video processing equipment are further improved.
Specifically, the preset display parameter data is target color data, such as a pixel point or an area on the first layer having the target color data. Further, as shown in fig. 7A, step S23 includes, for example:
s231 a: acquiring the color data of a target pixel point in the first layer;
s233 a: judging whether the color data of the target pixel point and the target color data meet a preset chromaticity condition;
s235 a: when the color data of the target pixel point and the target color data meet a preset chromaticity condition, assigning the transparency data of the target pixel point as non-completely opaque data; and
s237 a: and when the color data of the target pixel point and the target color data do not meet the preset chromaticity condition, assigning the transparency data of the target pixel point as completely opaque data.
Further, the preset chromaticity condition is that a difference between the color data of the target pixel and the target color data is smaller than a chromaticity difference threshold. That is, the preset chromaticity condition is that the difference value between the two is smaller than the chromaticity difference threshold. For example, the chrominance difference threshold may be, for example, 5. For example, when the target color data is green (0,255,0), the color data of a certain pixel point on the first layer is (0,250,0), and at this time, the difference between the two is equal to 5, which is not less than 5 of the chromaticity difference threshold, so that the pixel point does not satisfy the preset chromaticity condition, and the transparency data of the pixel point is assigned as completely opaque data. For another example, when the target color data is green (0,255,0), the color data of a certain pixel point on the first layer is (0,253,0), and at this time, the difference between the two is equal to 2, which is less than the chromaticity difference threshold 5, so that the pixel point satisfies the preset chromaticity condition, and therefore, the transparency data of the pixel point is assigned as non-completely opaque data, which may be 0, or a value less than 1, and is determined according to the user requirement.
Therefore, when the preset display parameter data is target color data, such as green (0,255,0), the color data of the target pixel point or the area on the first layer can be compared with the target color data, when the preset chromaticity condition is met, the transparency data of the target pixel point on the first layer is assigned to be non-completely opaque data, and when the preset chromaticity condition is not met, the transparency data of the target pixel point on the first layer is assigned to be completely opaque data, so that transparency processing (also called matting) is performed on the first layer to obtain a special-shaped layer, and partial pixel points or areas on the layer are not visible, so that a special-shaped area is obtained.
In another embodiment of the present invention, the preset display parameter data is target luminance data, for example, a pixel point or an area having the target luminance data on the first layer. As shown in fig. 7B, step S23 includes, for example:
s231 b: acquiring brightness data of a target pixel point in the first layer;
s233 b: judging whether the brightness data of the target pixel point and the target brightness data meet a preset brightness condition or not;
s235 b: and when the brightness data of the target pixel point meets a preset brightness condition, assigning the transparency data of the target pixel point as completely transparent data.
Further, the preset brightness condition is that the difference between the brightness data of the target pixel and the target brightness color data is smaller than a brightness difference threshold. That is, the preset brightness condition is that the difference value between the two is smaller than the brightness difference threshold. For example, the brightness difference threshold may be, for example, 100. For example, when the target brightness data is 1000, the brightness data of a certain pixel point on the first layer is 800, and at this time, the difference between the two is equal to 200, and the difference is not less than the brightness difference threshold 100, so that the pixel point does not satisfy the preset brightness condition, and therefore the transparency data of the pixel point is assigned as the incomplete transparency data, that is, the transparency data may be a numerical value that is less than or equal to 1 and greater than 0, and this is determined according to the user needs. For another example, when the target brightness data is 1000, the brightness data of a certain pixel point on the first layer is 960, and at this time, the difference between the two is equal to 40, and the value is smaller than the brightness difference threshold value 100, so that the pixel point satisfies the preset brightness condition, and the transparency data of the pixel point is assigned as completely transparent data, that is, the transparency data is, for example, 0.
Therefore, when the preset display parameter data is target brightness data, the brightness data of the target pixel point or the area on the first layer can be compared with the target color brightness data, when the preset brightness condition is met, the transparency data of the target pixel point on the first layer is assigned to be completely transparent data, when the preset chromaticity condition is not met, the transparency data of the target pixel point on the first layer is assigned to be incompletely transparent data, so that transparency processing (also called matting) is carried out on the first layer to obtain a special-shaped layer, and partial pixel points or areas on the layer are invisible, so that a special-shaped area is obtained.
Further, as shown in fig. 8, the method for implementing the special-shaped layer may further include:
s25: acquiring a second image layer;
s27: respectively carrying out scaling processing on the special-shaped image layer and the second image layer to obtain a scaled special-shaped image layer and a scaled second image layer;
s29: and overlapping the zoomed second image layer and the zoomed special-shaped image layer.
In order to facilitate understanding of the present invention, the following describes in detail each step of the method for implementing the profiled layer according to the embodiment of the present invention with reference to fig. 9A to 9C.
The method for realizing the special-shaped layer provided by the embodiment of the invention can be applied to video processing equipment to realize the superposition processing of the special-shaped layer. The video processing device here may be connected, for example, to a display screen or other display system such as a display controller and display control card and a display screen. The display screen may be, for example, an LED display screen, or may also be other display screens such as an LCD or other types of display screens, which is not limited in the present invention. Typically, the video processing device herein may be, for example, an electronic device having processing capability of superimposing layers or the like. It should be noted that the video processing apparatus herein may adopt the video processing apparatus shown in fig. 4A in the foregoing first embodiment, but unlike this, the programmable logic device 120 does not need to obtain, store and read the special-shaped transparency data template via the main control circuit 110, and perform transparency processing on the first image layer according to the special-shaped template.
The method for implementing the special-shaped layer provided by the embodiment of the invention mainly obtains the special-shaped layer by performing transparency processing on the first layer according to the preset display parameter data, solves the problem that a multimedia video server is required to implement the special-shaped layer in the prior art, is convenient, rapid and high in flexibility, reduces the equipment cost, and further improves the image processing capability and the display effect of video processing equipment.
Firstly, presetting display parameters as target color data
As shown in fig. 9A, the image source (also referred to as a first layer) of the programmable logic device 120 of the video processing apparatus 100, which receives an external input and is designed by a user in advance, to be subjected to transparency processing, has pixel points or regions of target color data, for example, an oval region where the target color data on the first layer is green. Programmable logic device 120 utilizes the first overlay windowing and transparency processing (also called matting). Meanwhile, the programmable logic device 120 performs windowing on an image source (also referred to as a second layer) that needs to be configured with a special shape. Then, the programmable logic device 120 reads the color data of the target pixel point in the first layer pixel point by pixel point, and then compares the color data with the target color data preset by the user to determine whether the color data and the target color data meet a preset chromaticity condition, for example, the difference between the color data and the target color data is smaller than a chromaticity difference threshold. The chroma difference threshold value can be set according to actual needs. When the condition is met, assigning the transparency data of the target pixel point as non-completely opaque data, namely, the transparency data can be partially transparent or completely transparent, for example, the value is not 1. And when the condition is not met, assigning the transparency data of the target pixel point as completely opaque data, for example, taking the value as 1. It is worth mentioning that the overlapping priorities of the first layer and the second layer need to be bound, the priorities of the first layer and the second layer are continuous, and meanwhile, the overlapping priority of the first layer is lower than that of the second layer, namely, after the first layer and the base map (or called background image) are well overlapped, the special-shaped layer is overlapped, so that the first layer after the matting can perform special-shaped processing on the second layer. As shown in fig. 9A, when the matting and scaling modified image layer is stacked with the second image layer, image pixel points of the second image layer corresponding to the green elliptic region with the transparency of 1 are visible, the image of the region with the transparency of 1 on the modified image layer can still be displayed and visible, and the image pixel points of the second image layer below the modified image layer are blocked by the modified image layer and are not visible.
It should be mentioned that, if the user does not enable the cutout function of the first layer, the transparency data a of all the pixel points in the first layer is 1, which indicates that the entire first layer is opaque, that is, the image of the second layer below is not displayed. In addition, before the special-shaped layer and the second layer are superposed, layer scaling processing can be performed on the special-shaped layer, so that the special-shaped layer and the second layer are consistent in size, and layer superposition can be performed better. The oval region may have other shapes, such as a rhombus, a circle, a star, a triangle, a crescent, and a pentagon.
Secondly, presetting display parameters as target brightness data
As shown in fig. 9B, the image source (also called a special-shaped layer) to be processed for transparency, which is designed by the user in advance and is received by the programmable logic device 120 of the video processing apparatus 100, is received, and the special-shaped layer has pixel points or regions of target brightness data, for example, a pentagonal region with target brightness data of 1000 on the special-shaped layer. Programmable logic device 120 utilizes the special-shaped layer windowing and transparency processing (also called matting). Meanwhile, the programmable logic device 120 performs windowing on an image source (also referred to as a second layer) that needs to be configured with a special shape. Then, the programmable logic device 120 reads the luminance data of the target pixel point in the special-shaped layer pixel point by pixel point, and then compares the luminance data with the target luminance data preset by the user to determine whether the difference between the luminance data and the target luminance data meets a preset luminance condition, for example, the difference between the luminance data and the target luminance data is smaller than a luminance difference threshold, for example, 50. The brightness difference threshold value can be set according to actual needs. When the condition is satisfied, assigning the transparency data of the target pixel point to be completely transparent data, for example, a value of 0. When the condition is not met, assigning the transparency data of the target pixel point as non-complete transparency data, for example, the value may be greater than 0 and less than or equal to 1. It is worth mentioning that the overlapping priorities of the special-shaped layer and the second layer need to be bound, the priorities of the special-shaped layer and the second layer are continuous, and meanwhile, the overlapping priority of the special-shaped layer is lower than that of the second layer, namely, after the special-shaped layer and a base map (or called background image) are overlapped, the special-shaped layer is overlapped, so that the special-shaped layer after image matting can perform special-shaped processing on the second layer. As shown in fig. 9B, when the matting irregular-shaped layer is superimposed on the second map, the image pixels of the irregular-shaped layer, which have transparency of 1 and are except for the pentagonal region, are invisible, and the image pixels of the second map layer below the irregular-shaped layer are visible; and image pixel points of a pentagonal area with the transparency not being 1 on the special-shaped layer are visible.
It is worth mentioning that if the user does not enable the matting function of the special-shaped layer, the transparency data a of all the pixel points in the special-shaped layer is 1, which indicates that the whole special-shaped layer is opaque, i.e., the image of the second layer below is not displayed. The pentagonal region may have another shape, such as a rhombus, an ellipse, a circle, a star, a triangle, or a crescent.
In addition, before the special-shaped layer and the second layer are superposed, layer scaling processing can be performed on the special-shaped layer, so that the special-shaped layer and the second layer are consistent in size, and layer superposition can be performed better.
Further, for the two manners of presetting the display parameter data (the color data manner and the luminance data manner), as shown in fig. 9C, the multiple layers may also be subjected to the special-shaped processing, that is, multiple special-shaped layers are obtained, for example, a third layer and a fourth layer shown in fig. 9C, and the specific implementation process may be, for example: the third image layer and the fourth image layer are respectively subjected to operations such as matting and zooming according to the scheme, and then are sequentially overlapped with the fifth image layer such as a background picture, so that the overlapped image has the special-shaped effect of the first special-shaped image layer and the second special-shaped image layer. Therefore, the processing capacity and the special-shaped display effect of the video processing equipment can be further improved.
In summary, the embodiment of the present invention obtains the special-shaped layer by performing transparency processing on the special-shaped layer by using the special-shaped layer having the pixels with the preset display parameter data, which solves the problem in the prior art that a multimedia video server is required to implement the special-shaped layer, and is convenient, fast, and highly flexible, and reduces the equipment cost, and further improves the image processing capability and the display effect of the video processing equipment. In addition, the abnormal processing of the layer is realized through different preset display parameter data modes, so that the abnormal processing is diversified, the various requirements of users are met, and the user experience degree and the satisfaction degree are improved.
