Step 201, receiving first image data from the processor, where the first image data is image data with a first resolution of an original screen adapting to a horizontal screen mode of the electronic device, the original screen is the same as the reload screen in size, the horizontal screen mode is that a number of pixels in a first width direction of the original screen is greater than a 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.
The first resolution may be 720px x 1080px, and the second resolution may be 720px x 1520px, where px is a pixel. In a color image, the image information of each pixel is usually represented by red, green, and blue intensities, and may also be represented by its hue, saturation, and brightness. Black and white images can be identified by gray values.

And 203, processing the first image data according to the first resolution and the second resolution to obtain second image data adapting to the reloading screen, wherein the processing at least comprises rotation processing, and the rotation processing is used for forming a data matrix adapting to the vertical screen mode.
The number of columns (corresponding to the width direction) of the data matrix in the vertical screen mode is smaller than the number of rows (corresponding to the height direction), and the input pixels can be accurately mapped to the corresponding screen positions after rotation processing, 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 reload screen includes: determining a third resolution adapting to the cross screen 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 adapting to the reloading screen.
For example, if the second resolution is 720px x 720px, the third resolution is 720px x 720px.
The rotation processing specifically refers to adjusting row data in the data matrix to column data, and adjusting column data to row data. I.e. a rotation process of the matrix. The data matrix includes image information for each pixel.
In this example, the bridge chip can reduce the original image data of the adaptive horizontal screen mode based on the resolution, and then convert the original image data to adapt to the screen of the vertical screen mode, so as to improve the stability of displaying the image after the screen of the electronic device is replaced.

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: the following is performed for each second pixel to obtain image data of said each second pixel: determining a first pixel subset corresponding to the second pixel currently processed 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 second pixel which is currently processed 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 ratio of each first pixel in the current second pixel area, wherein the effective area ratio is obtained by 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.
In this example, the bridge chip can locate the plurality of first pixels corresponding to the second pixels through the position consistency, and further determine the image data of the second pixels according to the area distribution of each first pixel, so as to comprehensively and accurately characterize the image characteristics of the pixel area.

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.
In this example, the bridge chip can perform rotation processing on the original image data in the horizontal screen mode to adapt to the vertical screen mode, and then perform reduction processing on the rotated image data based on the resolution, so as to improve the stability of image display after the screen of the electronic device is replaced.
In one possible example, the determining second image data adapted to the reload screen according to the fourth resolution, the second resolution, and the third image data includes: 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 partial or all areas 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.
In this example, the bridge chip can determine the pixel position corresponding relation through the fourth resolution and the second resolution, so that the distribution condition 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 pixels can be predicted, finally the second image data is obtained, and the accuracy of determining the image data of 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: the following is performed for each second pixel to obtain image data of said each second pixel: determining a first pixel subset corresponding to the second pixel currently processed 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 second pixel which is currently processed 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 ratio of each first pixel in the current second pixel area, wherein the effective area ratio is obtained by 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.
In this example, the bridge chip can locate the plurality of first pixels corresponding to the second pixels through the position consistency, and further determine the image data of the second pixels according to the area distribution of each first pixel, so as to comprehensively and accurately characterize 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 of the plurality of first pixels and the image data of each first pixel includes: determining the area occupation ratio of each first pixel relative to the self complete area according to the area distribution of each first pixel in the plurality of first pixels; and weighting the image data of the plurality of first pixels according to the image data of each first pixel and the area ratio to obtain the image data of the second pixel which is processed currently.
For example, as shown in fig. 2b, assume that the first resolution of the first image data is 3*3, in order from left to right, 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 x 2, in order from left to right, top to bottom:
a pixel a, a pixel b,
A pixel c and a pixel d;
then in connection with the legend it is determined that the first set of pixels corresponding to pixel a includes pixel 0 (area 100%), pixel 1 (area 50%), pixel 3 (area 50%), pixel 4 (area 25%),
the three-channel image information of the pixel a can be calculated as:
channel R: (0 x 100% +255 x 50% +0 x 50% +255 x 25%)/4=47.8
Channel G: (0 x 100% +0 x 50% +255 x 50% +0 x 25%)/4=31.9
Channel B: (255 x 100% +255 x 50% +0 x 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, thereby improving the comprehensiveness and accuracy.
In some possible examples, the determining the image data of the currently processed second pixel from the region distribution of each first pixel of the plurality of first pixels and the image data of each first pixel includes: determining the area occupation ratio of each first pixel relative to the self complete area according to the area 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 second pixel currently processed.
In this example, the image data of the first pixel with the largest area ratio can be directly considered as the image data of the second pixel, so that the method 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 adapting to a horizontal screen mode of the electronic device, and the original screen is the same as the screen changing module in size, and the horizontal screen mode refers to that the number of pixels of the original screen in a first width direction is greater than the number of pixels of the original screen in a first height direction, and the first image data forms a data matrix according to constraints of the first width direction and the first height direction; secondly, obtaining a second resolution of a reloading screen, wherein the reloading screen is in a vertical screen mode, and the vertical screen mode refers to that the number of pixels in a second width direction of the reloading screen is smaller than that of pixels in a second height direction, and image data supported by the reloading screen form a data matrix according to the constraint of the second width direction and the second height direction; thirdly, processing the first image data according to the first resolution and the second resolution to obtain second image data of the adaptive screen, wherein the processing at least comprises rotation processing, and the rotation processing is used for forming a data matrix of an adaptive vertical screen mode; and finally, controlling the reloading screen to display corresponding image information according to the second image data. Therefore, the bridging chip of the screen changing module can convert the first image data of the first resolution of the original screen which is originally adapted to the horizontal screen mode into the screen changing screen of the second resolution which is adapted to the vertical screen mode, so that the screen changing module can accurately identify the image data and display the image data, the situation that the image data cannot be accurately identified and displayed due to different screen specifications is avoided, and the success rate and the stability of image display after the screen changing module is used for electronic equipment are improved.
