Description

Image display control method, system, readable storage medium and electronic device
Technical Field
The present disclosure relates to the field of image display technologies, and in particular, to an image display control method, an image display control system, a readable storage medium, and an electronic device.
Background
With the vigorous development of electronic products, especially intelligent wearable products, people have more and more requirements on the shapes of image display areas, and the conventional rectangular display areas cannot meet the requirements of people on attractiveness, so that displaying images through circular display areas becomes a current research hotspot. For example, devices such as smartwatches are typically circular displays in which numbers and/or pointers or the like are displayed. The image to be displayed is usually rectangular, so that the circular display screen or the circular display area is different from the rectangular display screen or the rectangular display area, and the background or the foreground has unique characteristics in the aspects of rotation and the like when the image is displayed.
For example, when an image is displayed in a rectangular display screen or a rectangular display area, since the display area and the image to be displayed are both rectangular, the display area or the size of the image to be displayed may be adjusted so that the display area completely displays the image to be displayed. However, for the circular display area, no matter how the adjustment is made, the size of the display area cannot be made to coincide with the size of the image to be displayed. If the circular display area is positioned outside the image to be displayed, namely the size of the display area is larger than that of the image to be displayed, the problems of messy codes and the like in a part of the display area can be caused; if the circular display area is located inside the image to be displayed, that is, the size of the display area is smaller than that of the image to be displayed, a partial image in the image to be displayed cannot be displayed.
In practical application, in order to avoid the problem of code confusion in the display area, the size of the display area is usually set to be smaller than that of the image to be displayed, and in this case, even if some partial images in the image to be displayed cannot be displayed, the device still performs corresponding calculation on pixel points of the partial images which cannot be displayed, where the calculation may be superposition calculation, output calculation, rendering calculation, cache calculation, or the like. Therefore, the calculation amount of the equipment is large, and the calculation occupies more resources, so that the performance of the equipment is poor.

Detailed Description
The following detailed description of the embodiments of the disclosure refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating an image display control method according to an exemplary embodiment. As shown in fig. 1, the method may include the following steps.
In step 101, in the case where an image display request is received, a target display area of a display screen is determined, wherein the target display area has a circular ring shape.
In the present disclosure, the image display request is for requesting display of an image with a circular ring display area. Accordingly, the circular ring display area on the display screen can be determined upon receiving the image display request. Wherein the circular ring is equivalent to a hollow circle, the hollow circle has a small radius R, and the whole circle has a large radius R. When the small radius R is not equal to 0, the ring is a ring with the ring width of R-R, wherein R is larger than R.
In one possible approach, the determined target display area is located outside the image to be displayed (the image to be displayed is rectangular in shape), i.e., the size of the determined target display area is larger than the stored image to be displayed, and thus the target display area can be used to display the entire image to be displayed.
It is considered that if the target display area is located outside the image to be displayed, no image can be displayed in a partial area of the target display area, so that the partial area generates messy codes, and the viewing experience of a user is influenced. Therefore, in order to avoid the problem of the occurrence of the scrambling code in the target display area, in the present disclosure, the determined target display area is located inside the image to be displayed (the image to be displayed is in a rectangular shape), that is, the size of the target display area is smaller than the size of the image to be displayed, and the target display area is used only for displaying a partial image in the image to be displayed.
It should be noted that, the present disclosure does not specifically limit the determined shape of the target display area to be a circular shape or a circular ring shape with a ring width R-R, and the determination may be made according to actual display requirements.
In step 102, each pixel point of the image to be displayed is traversed to determine a target pixel point located in the target display area.
As in the background art, since an image located within the target display region can be displayed and an image located outside the target display region cannot be displayed within the target display region even by rotation, a partial image that cannot be displayed may not be calculated in order to reduce the amount of calculation. That is, in step 102, each pixel point in the image to be displayed needs to be traversed to determine the target pixel point located in the target display area.
It should be noted that, in the field of image technology, an image to be displayed is usually stored in a matrix form, and when traversing pixel points in the image to be displayed, the traversal is performed according to rows. For example, after traversing the pixels in the first row, traversing the pixels in the second row until all the pixels are traversed.
In a possible manner, whether the pixel point is located in the target display area can be judged according to the distance between the pixel point and the central point of the image to be displayed.
Illustratively, FIG. 2 is a schematic illustration of a display area and an image to be displayed, shown in accordance with an exemplary embodiment. As shown in fig. 2, a small circle R and a large circle R are created in the display screen, and the centers of the small circle R and the large circle R coincide with each other, and the size of the image to be displayed is 2W × 2H (W > ═ R, H > ═ R, and when W ═ H ═ R, the displayed circle is the inscribed circle of this square image). Firstly, determining the distance S between the pixel point traversed currently and the central point of the image to be displayed, then judging the size relationship between the distance S and R, R, and when S is larger than R and smaller than or equal to R, determining that the pixel point is positioned in the target display area.
Assuming that the size of the image to be displayed is 2W × 2H, the distance S between the currently traversed pixel point and the center point of the image to be displayed can be determined by the following formula, where the position coordinate of the currently traversed pixel point is (x, y):
S 2 ＝(x-W+0.5) 2 +(y-H+0.5) 2
in step 103, for each target pixel point, the target display information of the target pixel point is determined according to the preset rotation angle information and the first position of the target pixel point in the first coordinate system, where the first coordinate system is the coordinate system of the image to be displayed.
In step 104, each target pixel point is displayed according to the target display information of each target pixel point.
In this disclosure, only the target pixel point located in the target display area determined in step 102 is calculated to obtain the target display information of the target pixel point, and then the target display information of the target pixel point is displayed. A specific embodiment of determining the target display information will be described in detail below.
By adopting the technical scheme, firstly, a target display area of a display screen is determined, then, each pixel point in an image to be displayed is traversed to determine a target pixel point located in the target display area, and finally, only target display information of the target pixel point is calculated and displayed. Therefore, only the pixel points capable of being displayed are calculated, and compared with the method for calculating each pixel point of the whole image to be displayed in the related technology, the calculation amount can be effectively reduced, the system resources occupied by calculation are reduced, and the equipment performance is improved.
In order to facilitate better understanding of the image display control method provided by the present disclosure for those skilled in the art, a detailed description is given below with respect to a complete embodiment.
First, a specific embodiment in which step 101 in fig. 1 determines a target display area of a display screen in a case where an image display request is received will be described.
First, in response to receiving an image display request, a target number of circles, which is an integer greater than or equal to 1, whose centers coincide with each other when the target number is greater than or equal to 2, is created on a display screen.
Illustratively, the image display request may include a user's requirement for a target display area, which may include the size of the display area, the shape of the display area, and so on. For example, assuming that the user needs to display an image with a circular display area, a circle may be created in the display screen, and the size of the circle may be determined based on the size of the display area and/or the size of the display screen in the image display request. Further illustratively, assuming that a user needs to display an image with a display area in the shape of a circular ring having a certain ring width, a plurality of circles may be created in the display screen.
Thereafter, a target display area is determined in the target number of circles.
Assuming that a circle is created in the display screen according to the image display request, the area within the circle is the determined target display area. Assuming that a plurality of circles are created in the display screen according to the image display request, the plurality of circles may form a plurality of display areas in which the target display area is determined. Illustratively, three circles are created in the display screen of the smart watch, and are sequentially recorded as a circle r1, a circle r2 and a circle r3 from inside to outside, wherein a display area a1 is formed inside the circle r1, a display area a2 is formed by the circle r1 and the circle r2, and a display area a3 is formed by the circle r2 and the circle r3, so that it is preset to display a watch hand in the display area a1, display a time scale in the display area a2, display a date in the display area a3, and the like. Assuming that the image to be displayed in the image display request is time-scaled, the display area a2 is determined as the target display area.
Next, a specific embodiment of determining the target display information of the target pixel according to the preset rotation angle information and the first position of the target pixel in the first coordinate system in step 103 in fig. 1 will be described.
Illustratively, as shown in fig. 3, the step 103 may further include the steps of:
in step 1031, a second position of the target pixel point before rotation in the first coordinate system is determined according to the preset rotation angle information and the first position of the target pixel point in the first coordinate system.
As described above, the first coordinate system is a coordinate system of the image to be displayed, as shown in fig. 2, an original coordinate point of the first coordinate system is a position of an upper left-corner pixel in the image, a horizontal leftward straight line is an x-axis of the first coordinate system, a vertical downward straight line is a y-axis of the first coordinate system, and a coordinate axis in the first coordinate system represents a pixel in the image, for example, a pixel with coordinates (m, n) represents a pixel in an mth column and an nth row in the image. The coordinate system in which the circle is located is called the second coordinate, and the origin of the second coordinate coincides with the center point (W-0.5, -H +0.5) of the image to be displayed.
Assuming that the first position of the target pixel point in the first coordinate system is (x, y), the translated target pixel point in the first coordinate system is first transformed to the position in the second coordinate system (x1, y1) by the following formula:
x1＝x-W+0.5
y1＝y+H-0.5
then, a position (x2, y2) before the target pixel point rotates in the second coordinate system is determined according to the preset rotation angle information and the first position, wherein the preset rotation angle information includes a rotation direction and a rotation angle, for example, a clockwise direction is a positive rotation direction, and a counterclockwise direction is a negative rotation direction. Assuming that the preset rotation angle information is a positive rotation and a rotation angle a, the position (x1, y1) may be rotated counterclockwise by the rotation angle a to obtain a position (x2, y2) before the target pixel rotates in the second coordinate system, and for example, the position (x2, y2) before the target pixel rotates in the second coordinate system may be determined by referring to the following formula:
x2＝x1·cosA-y1·sin A
y2＝x1·sinA+y1·cos A
then, the position (x2, y2) before the target pixel point is rotated in the second coordinate system is converted into a second position (x3, y3) before the target pixel point is rotated in the first coordinate system by the following formula:
x3＝x2+W-0.5
y3＝y2-H+0.5
thus, the second position (x3, y3) before the target pixel point rotates in the first coordinate system can be obtained through the coordinate transformation.
In step 1032, the target display information of the target pixel point is determined according to the second position of the target pixel point.
It is worth noting that in the present disclosure, the second position (x3, y3) derived by trigonometric function back may be an integer or a decimal, wherein the decimal includes an integer part and a decimal part, due to the arbitrary angular rotation. Since the position of each pixel point in the image to be displayed is an integer, if the second position (x3, y3) only includes an integer part, the pixel value (which may be, for example, ARGB data or RGB data) of the pixel point located at the second position (x3, y3) may be directly determined as the target display information of the target pixel point. And if the coordinate value of the second position is a decimal, obtaining target display information of the target pixel point through interpolation operation.
For example, first, according to the integer part of the coordinate value of the second position, the pixel values of a preset number of adjacent pixel points are extracted from the image to be displayed. The preset number may be 2 × 2 (four), 3 × 3 (nine), 4 × 4 (16), and so on. Assuming that the second position of the target pixel point is (3.3 ) and the preset number is 2 × 2, the pixel values of four pixel points located at the (3, 3) position, (3, 4) position, (4,3) position and (4, 4) position in the image to be displayed can be extracted respectively.
And then, according to the decimal part of the coordinate value of the second position, utilizing the extracted pixel values of a preset number of adjacent pixel points to perform bilinear interpolation to obtain a target pixel value, wherein the target pixel value is target display information of the target pixel point.
It should be noted that, before the bilinear interpolation is used in the present disclosure, the corresponding precision level may be obtained for the decimal part of the coordinate value of the second position, and then the bilinear interpolation is performed by using the pixel values of the neighboring pixel points in the preset number, wherein the interpolation calculation is usually performed by using 8/16/32/64 step.
Therefore, according to the mode, the target display information of each target pixel point can be obtained.
It should be noted that, if the target display information of a target pixel is sent to the display screen for display after the target display information of the target pixel is determined, the number of transmission times is large, and therefore, in a possible implementation manner, after the target display information of the target pixel is determined, the target display information of the target pixel is stored in the target memory, so that the target display information of each target pixel can be stored in the target memory, and then, after the respective target display information of all the target pixels is determined, the stored target display information of all the target pixels is sent to the display screen, so that each target pixel is displayed in the target display area of the display screen.
In addition, considering that the number of target pixels is large, if the target display information of all the target pixels is stored in the target memory together, the memory may be in shortage, and therefore, in one embodiment, the target pixel information of the target pixels may be stored and sent to the display screen in multiple times. It should be noted that after the target display information currently stored in the target memory is sent to the display screen, when the target display information of other target pixel points is stored again, the target display information of the other target pixel points stored this time may cover the target display information stored last time, so that the space of the target memory may be reduced.
Illustratively, first, an image to be displayed is divided into a plurality of image blocks according to a preset division rule. In the field of image processing technology, when traversing the pixels of an image, traversal is usually performed according to rows, that is, all the pixels in the first row are traversed first, and after the traversal of the first row is completed, all the pixels in the second row are traversed, … …, until the last pixel in the last row is traversed. And traversing the pixels in any row from left to right.
Therefore, in the present disclosure, the preset division rule is a division rule by line. Assuming that the size of the image to be displayed is 800 × 800, the image can be divided into four image blocks with the same size, and each image block has a size of 200 × 800. It should be noted that, in practical applications, the sizes of the plurality of divided image blocks may not be completely the same, or may be completely the same, and the disclosure is not limited thereto.
And then, sequentially traversing each pixel point of each image block to determine a target pixel point positioned in the target display area in the currently traversed image block.
And then, displaying the target pixel point in the target display area in the currently traversed image block according to the target display information of the target pixel point in the target display area in the currently traversed image block.
For example, as shown in fig. 4, assuming that the size of the image to be displayed is 800 × 800, the image may be divided into four image blocks with the same size, where each image block has a size of 200 × 800, first, pixel points in a first image block (i.e., line 1 to line 200 of the image to be displayed) are traversed, a target pixel point located in a target display area in the first image block is determined, target display information of the target pixel point is determined and stored in a target memory, and then, the target display information of the target pixel point in the first image block stored in the target memory is sent to a display screen for display. Then, traversing the pixels in the second image block (i.e., the 201 st row to the 400 th row of the image to be displayed) in the same manner, determining target display information of the target pixels, storing the target display information in a target memory, and then sending the target display information of the target pixels in the second image block stored in the target memory to a display screen for display. And repeating the steps until the target display information of the target pixel point in the fourth image block is sent to the display screen for displaying.
It should be noted that, when the target display information of the target pixel point in the currently traversed image block is stored in the target memory, the target display information of the target pixel point of the currently traversed image block may cover the target display information of the target pixel point of the last traversed image block.
Therefore, by adopting the technical scheme, the target display information of the target pixel point is determined in a grading manner, the target display information is stored in a grading manner, and the target display information is sent to the display screen in a grading manner, so that the space of a target memory can be effectively reduced, and the performance of the equipment is further improved.
Based on the same inventive concept, the present disclosure also provides an image display control system. Fig. 5 is a block diagram illustrating an image display control system according to an exemplary embodiment. As shown in fig. 5, the system may include a read-write control device 501 and an image display control device 502, where the read-write control device 501 and the image display control device 502 are connected.
The read/write control device 501 is configured to provide a human-machine interface, where the human-machine interface is an interface for a user to input information, where the information may include an image display request, a preset rotation angle, and an image to be displayed, where a format of the image to be displayed may be RGB565 and ARGB 8888. In addition, the read/write control device 501 can also receive the precision ladder, the preset segmentation rule and the like input by the user. The present disclosure does not specifically limit this.
