At present, most of common manufacturers adopt software or chips to realize image processing after screen changing, but most of the chips on the market only can support one image RGB format input (such as RGB101010/RGB 888), and the universality is poor.
In view of the foregoing, the present application provides an image conversion method, an image conversion device, and a bridge chip, which are described in detail below.
Fig. 1 is a schematic diagram of an electronic device 100 provided in the present application. The electronic device 100 comprises a processor 110 and a reloading screen module 120, wherein the reloading screen module 120 comprises a bridge chip 121 and a reloading screen 122, the processor 110 is connected with the bridge chip, and the bridge chip 121 is connected with the reloading screen 122. The processor 110 may be a system-on-chip of the electronic device 100, and specifically includes a central processing unit CPU, a graphics processor 110GPU, and the like. The bridge chip 121 may be a Robin transcoding chip. The retrofit screen 122 may be, for example, an Active Matrix Organic Light Emitting Diode (AMOLED) screen liquid crystal display (Liquid Crystal Display, LCD) or the like.
Specifically, the electronic device 100100 may be any one of various electronic devices 100, such as a game console, a mobile terminal (such as a smart phone), an IoT device, a vehicle-mounted terminal device, and the like.
The information query method provided by the application is described in the following specific embodiments.
Referring to fig. 2, the present application provides an image conversion method applied to a bridge chip of a screen module of an electronic device shown in fig. 1, as shown in fig. 2, the method includes:
step 201, receiving first image data sent by the processor, wherein the first image data is stored with a first color depth.
For example, the first color depth may be 10 bits, and the RGB101010 mode is adapted, where the control data corresponding to the first color depth is stored as a first RGB value, where the bit depth of the first RGB value is 10 bits, and bit is a bit.
Step 202, obtaining a second color depth of a reloading screen of the electronic equipment.
For example, the second color depth is 8 bits, and the RGB888 mode is adapted, and the control data corresponding to the second color depth is stored as a second RGB value, where the bit depth of the second RGB value is 8 bits, and the bit is a bit.
Step 203, determining whether to perform color depth conversion on the first image data according to the first color depth and the second color depth.
In one possible embodiment, the determining whether to perform color depth conversion on the first image data according to the first color depth and the second color depth includes: when the first color depth is equal to the second color depth, performing no color depth conversion on the first image data; and when the first color depth is smaller than or larger than the second color depth, performing color depth conversion on the first image data.
It will be appreciated that when the first color depth is equal to the second color depth, the RGB mode of the image data between the processor and the retrofit screen is the same, so that no format conversion is required, and only when the first color depth is less than or greater than the second color depth, does the color depth conversion (i.e., RGB format conversion).
It can be seen that in this embodiment, triggering the color depth conversion mechanism under certain conditions is achieved.
And 204, converting the first color depth of the first image data into a second color depth to obtain second image data when the first image data is determined to need to be subjected to color depth conversion, wherein the second image data is the image data adapting to the reloading screen.
In one possible embodiment, the converting the first color depth of the first image data into the second color depth to obtain the second image data includes: and if the first color depth is smaller than or larger than the second color depth, converting the first RGB value of each pixel in the first image data into a second RGB value of the second image data in an equal proportion to obtain second image data.
Specifically, changing the first RGB value of the first image data may enable the first image data to be matched with the hardware parameter (i.e., the second color depth) and the RGB mode of the reloading screen, so that when it is determined that the first color depth is smaller or larger than the second color depth, the first RGB value of each pixel in the first image data is converted into the second RGB value of the second image data in equal proportion, and the second image data matched with the hardware parameter and the RGB mode of the reloading screen is obtained.
It can be seen that in this embodiment, when the RGB mode of the first image data is inconsistent with the reloading screen, the first RGB value of the first image data is converted into the second RGB value, so as to implement the adaptation of the first image data and the reloading screen.
In a possible embodiment, after the converting the first RGB value of each pixel in the first image data into the second RGB value of the second image data in equal proportion, the method further includes: acquiring a first resolution of the first image data; detecting a second resolution of the reloading screen; and carrying out resolution and color depth adaptation processing on the first image data according to the first resolution and the second resolution to obtain second image data adapting to the reloading screen.
For example, 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.
Specifically, after the RGB mode conversion is completed, whether the resolution ratio between the reloading screen and the original screen is changed is further determined, and if yes, the second image data needs to be adapted according to the second resolution ratio of the reloading screen.
It can be seen that in this embodiment, the adaptation between the RGB mode of the retrofit screen and the resolution is achieved after the replacement of the screen.
In a possible embodiment, the performing resolution and color depth adaptation processing on the first image data according to the first resolution and the second resolution includes: when the first resolution is larger than the second resolution, determining the proportion of the first resolution to the second resolution, and establishing a pixel position corresponding relation between an original screen and a reloading screen according to the proportion, wherein the pixel position corresponding relation comprises 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; establishing a mapping relation between the second RGB value and the second pixel; determining the image data of each second pixel according to the pixel position corresponding relation, the mapping relation and the first 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 correspondence through the first 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; in addition, after determining the image information of the second pixel, the bridge chip can also establish a mapping relationship between the second RGB value and the second pixel, so as to control the second pixel to display according to the second RGB value.
In a possible embodiment, the establishing a mapping relationship between the second RGB values and the second pixels includes: and establishing a mapping relation between the second RGB value and the second pixel on the reloading screen by taking the second pixel as a basic pixel unit.
Specifically, the first RGB value and the second RGB value are corresponding to the color parameters of a single pixel, so that after the color depth conversion, the pixel occupied by the first RGB value is unchanged, but the number of pixels of the reloading screen is different from that of the original screen, and therefore, the second RGB value and the second pixel of the reloading screen need to be remapped so as to display a complete color pattern on the reloading screen.
In one possible embodiment, the determining the image data of each second pixel according to the pixel position correspondence, the mapping relationship, 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 of 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, the image data of each first pixel and the mapping relation.
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.
For example, as shown in fig. 3, assume that the first resolution of the first image data is 3*3, which is 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.
Step 205, sending the second image data to the reloading screen so as to display a corresponding image through the reloading screen.
In summary, the image conversion method provided in the present application is applied to a bridge chip of a reloading screen module of an electronic device, where the electronic device includes a processor and a reloading screen module, the reloading screen module includes the bridge chip and a reloading screen, the processor is connected to the bridge chip, and the bridge chip is connected to the reloading screen, and the method includes: receiving first image data sent by the processor, wherein the first image data is stored in a first color depth; acquiring a second color depth of a reloading screen of the electronic equipment; determining whether to perform color depth conversion on the first image data according to the first color depth and the second color depth; when the first image data is determined to need to be subjected to color depth conversion, converting the first color depth of the first image data into a second color depth to obtain second image data, wherein the second image data is image data adapting to the reloading screen; and sending the second image data to the reloading screen so as to display corresponding images through the reloading screen.
