Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort shall fall within the protection scope of the present application.

The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this application and the drawings described above, are intended to cover non-exclusive inclusions. For example, a process, method, or system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. Further, the terms "first" and "second" are used to distinguish different objects, and are not used to describe a particular order.

An optional embodiment of the present application provides a picture processing method, which may be applied to various display devices with display functions, such as a television, a mobile phone, a tablet computer, a notebook computer, a palm computer, a personal digital assistant, a display, a self-service terminal, and an electronic billboard, and may also be applied to a computing device, such as a desktop computer and a cloud server, where the picture processing method is executed by a processor in the display device or the computing device.

As shown in fig. 1, an image processing method provided in an embodiment of the present application includes:

step S101, processing the picture into at least two picture units of a preset pixel size.

In application, the picture may be a power-on icon or a power-off icon of the display device, or may be a common icon or picture stored in the display device or the computing device.

In application, the preset pixel size may be set according to actual needs, for example, the size may be set as the size of the maximum pixel capacity supported by one storage unit in the RAM of the display chip, or the size of the picture may be an integral multiple of the preset pixel size. When the size of the preset pixel is fixed, if the size of the picture is not integral multiple of the size of the preset pixel, the pixel is added at the frame position of the picture, so that the size of the picture is integral multiple of the preset pixel. The principle followed by adding pixels at the frame position of the picture is to add the least number of pixels under the condition of ensuring that the size of the picture after the pixels are added is integral multiple of the preset pixels.

In application, assuming that the size of one picture is (41 × 12) × (13 × 18) pixels, and the maximum pixel capacity supported by the storage unit is 12 × 18 pixels, the picture can be divided into 41 × 13 picture units with the size of 12 × 18 pixels. If the picture is not processed, storing the picture will occupy the storage space of (41 × 12) × (13 × 18)/(12 × 18) =533 storage units. Assuming that the size of the memory space of the RAM is only 2 PAGEs (PAGEs), and one PAGE has 256 memory units, the size of the picture exceeds the memory space of the RAM, and therefore, the picture needs to be compressed to reduce the size of the picture.

Fig. 2 exemplarily shows a picture with a size of (41 × 12) × (13 × 18) pixels, and the picture in fig. 2 has been divided into 41 × 13 picture units with a size of 12 × 18 pixels; for ease of illustration, each pixel in the picture is not further shown in fig. 2.

In an alternative embodiment, step S101 is preceded by:

setting a display unit with a preset pixel size;

step S101 includes:

and processing the picture into at least two picture units with preset pixel size by taking the display unit as a reference template.

In application, a display unit with a preset pixel size can be preset, the size of each pixel in the display unit is the same as that of each pixel in a picture, then the picture is processed into at least two picture units by taking the display unit as a reference template, and the size of the display unit is the same as that of the picture units and can be adjusted in a self-defining mode according to actual needs.

It should be understood that, when the size of the picture is smaller than the size of two picture units, it indicates that the size of the picture itself is smaller, and the occupied storage space is small, and the picture does not need to be processed by using the picture processing method provided in this embodiment.

In an alternative embodiment, before step S101, the method includes:

detecting the size of the picture;

and when the size of the picture is smaller than twice the preset pixel size, storing the picture.

Fig. 3 exemplarily shows a black display unit after binarization processing of 12 × 18 pixels in size. The functions of the elements shown in fig. 3 are as follows:

0 in the black frame on the left of the display unit represents a black pixel, the gray value of 0,1 represents a white pixel, and the gray value is 1;

the toolbar on the right side of the display unit is used for setting parameters of the display unit;

the frame corresponding to the Name is used for setting the Name of the display unit in a user-defined mode;

the frame corresponding to the X is used for self-defining the number of the row pixels of the display unit;

the frame corresponding to the Y is used for setting the number of the row pixels of the display unit in a user-defined mode;

UP, right, left and Down orientation buttons for moving the pixels in the display unit UP, down, left and Right to adjust the orientation of the pixels in the display unit;

u (UP, up)/D (Down) and L (Left )/R (Right) are used for moving the display unit UP, down, left and Right, and the orientation of the display unit is adjusted;

clear means clearance;

inv denotes negation;

update represents Update;

close indicates closing the current display interface.

And step S102, acquiring display parameters of each picture unit.

In an application, the display parameters include color data, i.e. RGB values, of each pixel in a picture unit, and if the picture is a grayscale map, the color data is a grayscale value of each pixel.

And S103, when the number of the picture units with the same display parameters is larger than 1, reserving one of the picture units with the same display parameters to generate the simplified picture.

In application, the display parameters of two or more picture units are the same, which means that the color data of all the pixel points at the same position in the picture units with the same display parameters are the same. The pixel points at the same position refer to pixel points at the same position in two or more picture units, for example, if the display parameters of the picture unit a and the picture unit B are the same, the color data of the pixel points in the first row and the first column in the picture unit a and the color data of the pixel points in the first row and the second column in the picture unit a are the same as the color data of the pixel points in the first row and the second column in the picture unit B, … …, the pixel points in the mth row and the nth column in the picture unit a and the pixel points in the mth row and the nth column in the picture unit B are the same, and so on; wherein M is not less than 1,N is not less than 1, M is an integer, and N is an integer.

The display parameters of picture elements located at positions 0 (row position) 1 (column position) to 08, 0F to 014, and 01B to 01F in fig. 2 are the same.

In an application, a reduced picture is a picture after redundant same picture units are removed.

Fig. 4 exemplarily shows a reduced picture processed by the picture shown in fig. 2, wherein the reduced picture has a size equal to the size of 172 picture units or 172 storage units, and is reduced by (533-172)/533 =67.73% compared to the size of 533 picture units or 533 storage units of the original picture.

Step S104, storing the simplified picture; and each line of picture units in the picture corresponds to one addressing address in the simplified picture.

In the application, the generated and stored detailed attribute information of the simplified picture records addressing addresses corresponding to each row of picture units in the original picture, and each addressing address comprises a sub-addressing address corresponding to each picture unit in each row of picture units, so that the picture can be restored according to the sub-addressing address corresponding to each picture unit when the simplified picture needs to be restored into the picture.

FIG. 5 schematically shows 13 addressing addresses corresponding to 13 picture elements in the picture shown in FIG. 2; the NEXT or END is taken as a boundary, two rows before each NEXT or END are taken as an addressing address, each addressing address comprises 41 sub-addresses, and the addressing addresses correspond to 41 picture units in each row of picture units.

In an alternative embodiment, before step S104, the method includes:

and establishing an association relation between each row of picture units in the picture and one addressing address in the simplified picture.

In application, the association relationship may be a correspondence relationship or a mapping relationship, a correspondence relationship table or a mapping relationship table may be established to represent the association relationship, the correspondence relationship table or the mapping relationship table may be implemented by a look-up table (LUT), or may be implemented by other data tables or Random Access Memory (RAM) type storage media having the same input data function, that is, a function of looking up corresponding output data according to input data.

step S105, addressing the simplified picture according to the addressing address corresponding to each row of picture units in the picture;

and S106, sequencing the pixels in a row of picture units corresponding to each addressing address according to the addressing result so as to restore the picture.

In application, after the image is compressed and stored, if the image is to be restored and restored for display, the image can be restored by addressing according to the addressing address carried by the simplified image and sequencing the addressing result according to the addressing sequence.

As shown in fig. 6, in another embodiment of the present application, step S101 includes:

step S1011, processing the picture into at least two black-and-white picture units with preset pixel size;

the picture processing method further comprises the following steps:

step S107, generating a color palette with preset color digits according to the colors of the pictures;

after step S106, the method includes:

step S108, calling a coloring function, importing the data of the palette, and restoring the color of each picture unit in the picture.

In application, a binarization process may be performed on a picture, and a gray value of each pixel in the picture is processed to be 0 or1, so as to process the picture into a black-and-white picture, for example, the picture is processed by using the display unit shown in fig. 3, so as to obtain a black-and-white picture including at least two picture units.

In application, after a picture is processed into a black-and-white picture, the finally stored simplified picture is also black-and-white, and in order to restore the color of the picture when the picture is restored, a color palette with preset color digits is required to be generated in advance according to the color of the picture. The value range of the preset color digit is determined by the color digit supported by the display device or the computing device. For example, if the display device or the computing device supports a maximum 16-bit color bit number, the value range of the preset color bit number is 0 to 16 bits.

In application, the display device or the computing device runs the palette generation software, and the implementation code for generating a 16-bit palette according to the colors of the picture is as follows:

BYTE code tPALETTE_0[]＝

{

0x00,0x00,0x00,//black

0xff,0xff,0xff,//white

0xff,0xff,0x00,

0x00,0x00,0x80,

0xff,0x00,0xff,

0x00,0x80,0x00,

0xff,0x00,0x00,

0x00,0x80,0x80,

0x00,0xff,0xff,

0x80,0x00,0x00,

0x00,0xff,0x00,

0x80,0x00,0x80,

0x00,0x00,0xff,

0x80,0x80,0x00,

0x80,0x80,0x80,

0xc0,0xc0,0xc0,

}

in application, step S107 may be performed at any time prior to step S108.

In an alternative embodiment, step S108 includes:

calling RTDOsdFuncChangcolor 1Bit (ROW (X), COL (Y), WIDTH (W), HEIGHT (H), COLOR (FG, BG), _ FONTFROM _0 _255) and importing the data of the palette to restore the COLOR of the picture element;

wherein, X is the number of rows, Y is the number of columns, W is the width, H is the height, FG is the foreground color, BG is the background color, FG and BG are the data of the palette which is directly imported.

In an alternative embodiment, the shading functions include a first shading function and a second shading function;

and when the color of the picture unit is a single color, calling the first coloring function or the second coloring function and importing the data of the color palette to restore the color of the picture unit.

In an alternative embodiment, the second shading function is: RTDOsdFuncChangcolor 1Bit ()

In application, the first coloring function is the function rtdosdfinchangecolor 1Bit (ROW (X), COL (Y), WIDTH (W), HEIGHT (H), COLOR (FG, BG), _ FONTFROM _0 \, 255), and when the picture element is any COLOR, the function can be used to COLOR; when the picture unit is monochrome, a second coloring function can be adopted for coloring so as to simplify a coloring program, reduce the data operation amount and improve the coloring speed.

In an alternative embodiment, step S101 is preceded by:

identifying background pixels in the picture;

filtering the background pixels and reserving foreground pixels in the picture;

or, identifying foreground pixels in the picture;

the foreground pixels are retained.

In application, background pixels (for example, black background pixels in fig. 2) in a picture can be filtered out through pixel identification and filtering software, only foreground pixels are reserved, and the colors of the background pixels are the same, so that only the colors of the background pixels and the size of the picture need to be recorded, and when the picture is restored, parts except the foreground pixels are filled as the background pixels according to the colors of the background pixels and the size of the picture. The background pixels may be directly identified and filtered, or only the foreground pixels in the picture may be identified and only the foreground pixels may be retained.
