At present, most of common manufacturers adopt software or chips to realize image processing after screen changing, but most of chips in the market can only support input in one image RGB format (such as RGB101010/RGB888), and the universality is poor.
In view of the above problems, the present application provides an image conversion method, an image conversion apparatus and a bridge chip, which will be described in detail below.
As shown in fig. 1, fig. 1 is a schematic view of an electronic device 100 provided in the present application. The electronic device 100 comprises a processor 110 and a screen replacing module 120, wherein the screen replacing module 120 comprises a bridge chip 121 and a screen replacing screen 122, the processor 110 is connected with the bridge chip, and the bridge chip 121 is connected with the screen replacing 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 exchangeable screen 122 may be, for example, an Active Matrix/Organic Light Emitting Diode (AMOLED) screen 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 machine, a mobile terminal (e.g., a smart phone), an IoT device in the internet of things, and a vehicle-mounted terminal device.
The following describes an information query method provided by the present application with 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, where as shown in fig. 2, the method includes:
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, and the bit depth of the first RGB value is 10 bits, and bit is a bit.
For example, the second color depth is 8 bits, the RGB888 mode is adapted, the control data corresponding to the second color depth is stored as a second RGB value, the bit depth of the second RGB value is 8 bits, and bit is a bit.
In one possible embodiment, the determining whether to color depth convert 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, not performing 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 pattern of the image data between the processor and the conversion screen is the same, and therefore no format conversion is required, only when the first color depth is less than or greater than the second color depth, a color depth conversion (i.e. RGB format conversion) is required.
It can be seen that in this embodiment, a mechanism is implemented to trigger color depth conversion in certain situations.
In a 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 the second RGB value of the second image data in an equal proportion to obtain second image data.
Specifically, the first RGB value of the first image data may be changed to be adapted to 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 than or larger than the second color depth, the first RGB value of each pixel in the first image data is proportionally converted into the second RGB value of the second image data, and the second image data adapted to 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 that the adaptation of the first image data and the reloading screen is realized.
In one possible embodiment, after the first RGB value of each pixel in the first image data is proportionally converted into the second RGB value of the second image data, the method further includes: acquiring a first resolution of the first image data; detecting a second resolution of the reloading screen; and carrying out adaptation processing of resolution and color depth on the first image data according to the first resolution and the second resolution to obtain second image data adapted to the reloading screen.
For example, the first resolution may be 1920px 1080px, the second resolution may be 720px 1520px, and px is a pixel. In a color image, the image information of each pixel is usually represented by the intensity of red, green and blue, and can also be represented by its hue, saturation, and brightness. The black and white image can be identified by the gray value.
Specifically, after the RGB mode conversion is completed, it is determined whether there is a change in resolution between the reloading screen and the original screen, and if there is a change in resolution between the reloading screen and the original screen, the second image data needs to be adapted according to the second resolution of the reloading screen.
It can be seen that, in the embodiment, after the screen is replaced, and the RGB mode and the resolution are adapted.
In one 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 greater 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 corresponding relation between a first pixel subset and a second pixel, the first pixel subset comprises part 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; 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.
As can be seen, in this example, the bridge chip can determine the pixel position corresponding relationship through the first 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 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; in addition, after the image information of the second pixel is determined, the bridge chip can also establish a mapping relation between a second RGB value and the second pixel 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 a 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 correspond to color parameters of a single pixel, and therefore, after color depth conversion, the occupied pixel is not changed, but the number of pixels of the screen to be changed is different from that of the original screen, and therefore, the second RGB value and the second pixel of the screen to be changed need to be remapped so as to display a complete color pattern on the screen to be changed.
In a possible embodiment, the determining the image data of each second pixel according to the pixel position corresponding relationship, the mapping relationship 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 of 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, the image data of each first pixel and the mapping relation.
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.
For example, as shown in fig. 3, assume that the first resolution of the first image data is 3 × 3, and the first resolution 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 fraction 100%), pixel 1 (area fraction 50%), pixel 3 (area fraction 50%), pixel 4 (area fraction 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
And 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.
To sum up, the image conversion method provided by the application is applied to a bridge chip of a screen module of an electronic device, the electronic device comprises a processor and the screen module, the screen module comprises the bridge chip and a screen, the processor is connected with the bridge chip, the bridge chip is connected with the screen, and the method comprises the following steps: receiving first image data sent by the processor, wherein the first image data is image data stored with 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 it is determined that color depth conversion needs to be performed on the first image data, 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 adapted to the reloading screen; and sending the second image data to the reloading screen so as to display a corresponding image through the reloading screen. In the embodiment, the format of the first image data is converted according to the second color depth of the reloading screen, so that the universality of the bridge chip is improved, and the electronic equipment can adapt to various reloading screens.
