In view of the above problems, the present application provides an image data processing method and related apparatus, which will be described in detail below.
Referring to fig. 1, fig. 1 is a schematic view of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 includes a processor 120 and a screen replacing module 140, the screen replacing module 140 includes a bridge chip 141 and a screen replacing screen 142, the processor 120 is connected to the bridge chip 141, and the bridge chip 141 is connected to the screen replacing screen 142. The processor 120 may be a system-on-chip of an electronic device, and specifically includes a central processing unit CPU, a graphics processing unit GPU, and the like. The bridge chip 141 may be a Cortex-M0 microprocessor. The reloading screen 142 may be, for example, an Active Matrix/Organic Light Emitting Diode (AMOLED) screen.
In addition, the electronic device 100 may be a game machine, a mobile terminal (e.g., a smart phone), an IoT device in the internet of things, a vehicle-mounted terminal device, and other various electronic devices.
Referring to fig. 2a, fig. 2a is a schematic flowchart of an image data processing method according to an embodiment of the present disclosure, and is applied to a bridge chip 141 of a screen replacing module 140 of an electronic device 100 shown in fig. 1; as shown in the figure, the image data processing method includes the following steps.
Step 201, receiving first image data from the processor, where the first image data is image data of a first resolution of an original screen in a landscape mode adapted to the electronic device, the original screen and the reloading screen are the same in size, and the landscape mode is that the number of pixels in a first width direction of the original screen is greater than the number of pixels in a first height direction, and the first image data forms a data matrix according to constraints in the first width direction and the first height direction.
Wherein the first resolution may be 1920px × 1080px, the second resolution may be 720px × 1520px, px being pixels. In a color image, the image information of each pixel is usually represented by the intensity of red, green and blue, and may also be represented by its hue, saturation, and brightness. The black and white image can be identified by the gray value.
Step 202, obtaining a second resolution of the reloading screen, wherein the reloading screen is in a vertical screen mode, and the vertical screen mode means that the number of pixels in a second width direction of the reloading screen is smaller than the number of pixels in a second height direction, and image data supported by the reloading screen forms a data matrix according to constraints in the second width direction and the second height direction.
Step 203, processing the first image data according to the first resolution and the second resolution to obtain second image data adapted to the reloaded screen, wherein the processing at least comprises rotation processing, and the rotation processing is used for forming a data matrix adapted to the vertical screen mode.
The column number (corresponding to the width direction) of the data matrix of the vertical screen mode is smaller than the row number (corresponding to the height direction), and after rotation processing, input pixels can be accurately mapped to corresponding screen positions, so that the accuracy and stability of image display are ensured.
And 204, controlling the reloading screen to display corresponding image information according to the second image data.
In one possible example, the processing the first image data according to the first resolution and the second resolution to obtain second image data adapted to the reloading screen includes: determining a third resolution for adapting the landscape mode according to the second resolution; determining fourth image data from the first resolution, the third resolution, and the first image data; and performing rotation processing on the fourth image data to obtain second image data matched with the reloading screen.
For example, if the second resolution is 720px × 1520px, the third resolution is 1520px × 720px.
The rotation processing specifically refers to adjusting row data in the data matrix into column data, and adjusting the column data into row data. I.e. a rotation process of the matrix. The data matrix includes image information for each pixel.
As can be seen, in this example, the bridge chip can perform reduction processing on the original image data adapted to the horizontal screen mode based on the resolution, and then perform conversion processing to adapt to the screen of the vertical screen mode, so as to improve the stability of image display after the screen of the electronic device is adapted.
In this possible example, the determining fourth image data from the first resolution, the third resolution, and the first image data comprises: determining a pixel position corresponding relation between the original screen and the reloading screen according to the first resolution and the third resolution, wherein the pixel position corresponding relation comprises a corresponding relation between a first pixel subset and a second pixel, the first pixel subset comprises a part of or all of a plurality of first pixels, the first pixels are pixels of the original screen, the second pixels are pixels of the reloading screen, and the combination of the plurality of first pixels in each first pixel subset is the same as the position of the corresponding second pixels; determining the image data of each second pixel according to the pixel position corresponding relation and the first image data; and determining second image data of the reloading screen according to the image data of each second pixel.
As can be seen, in this example, the bridge chip can determine the pixel position corresponding relationship through the first resolution and the third resolution, so that the distribution of the first pixels corresponding to the position area where each second pixel of the single frame image of the reloading screen is located can be accurately determined, and the image information of each first pixel in the first image data is known, so that the image information of the second pixel can be predicted, the second image data is finally obtained, and the accuracy of determining the image data adapted to the reloading screen is improved.
In this possible example, the determining the image data of each second pixel according to the pixel position correspondence and the first image data includes: performing the following operation for each second pixel to obtain the image data of each second pixel: determining a first pixel subset corresponding to a currently processed second pixel according to the pixel position corresponding relation; determining image data for each of a plurality of first pixels in the first subset of pixels from the first image data; and determining the image data of the currently processed second pixel according to the area distribution of each first pixel in the plurality of first pixels and the image data of each first pixel.
The area distribution is used for representing the effective area occupation ratio of each first pixel in the current second pixel area, the effective area occupation ratio is obtained by specifically dividing the effective area of the first pixel by the whole area of the first pixel, and the effective area of the first pixel refers to the pixel area in the second pixel area.
As can be seen, in this example, the bridge chip can locate a plurality of first pixels corresponding to the second pixels through position consistency, and further determine image data of the second pixels according to the area distribution of each first pixel, so as to comprehensively and accurately represent the image characteristics of the pixel area.
In one possible example, the processing the first image data according to the first resolution and the second resolution to obtain second image data adapted to the reloading screen includes: rotating the first image data according to the first resolution to obtain third image data of a fourth resolution adapted to the vertical screen mode; and determining second image data adapting to the reloading screen according to the fourth resolution, the second resolution and the third image data.
Wherein the width of the fourth resolution is greater than the width of the second resolution, and the height of the fourth resolution is greater than the height of the second resolution.
As can be seen, in this example, for the original image data adapted to the horizontal screen mode, the bridge chip can firstly rotate the original image data to adapt to the vertical screen mode, and then reduce the rotated image data based on the resolution, so as to improve the stability of image display after the electronic device changes the screen.
In one possible example, the determining second image data that fits the reloading screen from the fourth resolution, the second resolution and the third image data comprises: determining a pixel position corresponding relation between the reloading screen and the original screen according to the fourth resolution and the second resolution, wherein the pixel position corresponding relation comprises a corresponding relation between a first pixel subset and a second pixel, the first pixel subset comprises a part of or all of a plurality of first pixels, the first pixels are pixels of the original screen, the second pixels are pixels of the reloading screen, and the combination of the plurality of first pixels in each first pixel subset is the same as the position of the corresponding second pixel; determining the image data of each second pixel according to the pixel position corresponding relation and the third image data; and determining second image data of the reloading screen according to the image data of each second pixel.
As can be seen, in this example, the bridge chip can determine the pixel position corresponding relationship through the fourth resolution and the second resolution, so that the distribution of the first pixels corresponding to the position area where each second pixel of the single-frame image of the reloading screen is located can be accurately determined, and the image information of each first pixel in the first image data is known, so that the image information of the second pixel can be predicted, the second image data is finally obtained, and the accuracy of determining the image data adapted to the reloading screen is improved.
In one possible example, the determining the image data of each second pixel according to the pixel position correspondence and the third image data includes: performing the following operation for each second pixel to obtain the image data of each second pixel: determining a first pixel subset corresponding to a currently processed second pixel according to the pixel position corresponding relation; determining image data for each of a plurality of first pixels in the first subset of pixels from the third image data; and determining the image data of the currently processed second pixel according to the area distribution of each first pixel in the plurality of first pixels and the image data of each first pixel.
The area distribution is used for representing the effective area occupation ratio of each first pixel in the current second pixel area, the effective area occupation ratio is obtained by specifically dividing the effective area of the first pixel by the whole area of the first pixel, and the effective area of the first pixel refers to the pixel area in the second pixel area.
As can be seen, in this example, the bridge chip can locate a plurality of first pixels corresponding to the second pixels through position consistency, and further determine image data of the second pixels according to the area distribution of each first pixel, so as to comprehensively and accurately represent the image characteristics of the pixel area.
In one possible example, the determining the image data of the currently processed second pixel according to the area distribution of each first pixel in the plurality of first pixels and the image data of each first pixel comprises: determining the area ratio of each first pixel relative to the self complete region according to the region distribution of each first pixel in the plurality of first pixels; and according to the image data of each first pixel and the area ratio, carrying out weighting processing on the image data of the plurality of first pixels to obtain the image data of the currently processed second pixel.
For example, as shown in fig. 2b, assume that the first resolution of the first image data is 3*3, which is, in order from left to right and from top to bottom:
pixel 0, pixel 1, pixel 2,
Pixel 3, pixel 4, pixel 5,
Pixel 6, pixel 7, pixel 8;
the corresponding first image data is a matrix as follows:
(0,0,255)、(255,0,255)、(255,0,0)
(0,255,255)、(255,0,0)、(0,0,255)
(0,255,0)、(255,255,255)、(0,0,0)
the second resolution of the second image data is 2*2, which is, in order from left to right and from top to bottom:
pixel a, pixel b,
Pixel c, pixel d;
then it is determined in connection with the legend that the first set of pixels to which pixel a corresponds includes pixel 0 (area ratio 100%), pixel 1 (area ratio 50%), pixel 3 (area ratio 50%), pixel 4 (area ratio 25%),
the three-channel image information of the pixel a can be calculated as follows:
and (3) a channel R: (0 × 100% +255 × 50% +0 × 50% +255 × 25%) + 4=47.8
A channel G: (0 × 100% +0 × 50% +255 × 50% +0 × 25%) + 4=31.9
And (3) a channel B: (255 × 100% +255 × 50% +0 × 25%) + 4=127.5
The other pixels b, c and d are calculated in a similar way.
In this example, the bridge chip can accurately and comprehensively determine the image data of the second pixel based on the area ratio of each first pixel, so that the comprehensiveness and the accuracy are improved.
In some possible examples, the determining the image data of the currently processed second pixel according to the area distribution of each of the plurality of first pixels and the image data of each of the plurality of first pixels includes: determining the area ratio of each first pixel relative to the self complete region according to the region distribution of each first pixel in the plurality of first pixels; and selecting the image data corresponding to the first pixel with the largest area ratio as the image data of the currently processed second pixel.
As can be seen, in this example, the image data of the first pixel having the largest area ratio can be directly identified as the image data of the second pixel, which is simple and efficient.
It can be seen that, in the embodiment of the present application, a bridge chip of a screen changing module of an electronic device first receives first image data from a processor, where the first image data is image data of a first resolution of an original screen in a landscape mode adapted to the electronic device, and the original screen and the screen changing module have the same size, and the landscape mode is that the number of pixels in a first width direction of the original screen is greater than the number of pixels in a first height direction, and the first image data forms a data matrix according to constraints in the first width direction and the first height direction; secondly, acquiring a second resolution of the reloading screen, wherein the reloading screen is in a vertical screen mode, the vertical screen mode is that the number of pixels in a second width direction of the reloading screen is smaller than that in a second height direction, and image data supported by the reloading screen forms a data matrix according to constraints in the second width direction and the second height direction; processing the first image data according to the first resolution and the second resolution to obtain second image data adaptive to the reloading screen, wherein the processing at least comprises rotation processing, and the rotation processing is used for forming a data matrix adaptive to a vertical screen mode; and finally, controlling the reloading screen to display corresponding image information according to the second image data. It is thus clear that the bridging chip of the screen module of changing the outfit can convert the first image data of the first resolution ratio of the original dress screen of the original adaptation horizontal screen mode into the screen of changing the outfit of the second resolution ratio of the perpendicular screen mode of adaptation to make the screen of changing the outfit can accurately discern image data and show, avoid leading to accurate discernment and demonstration image data because of the screen specification is different, be favorable to improving the success rate and the stability that carry out the image display behind the electronic equipment screen of changing the outfit.
