Referring to fig. 3, a schematic diagram of a bang screen in an embodiment of the present invention is shown. Fig. 4 is a schematic diagram of a circular corner screen in an embodiment of the invention. Figure 5 provides a partial schematic view of a radiused screen in an embodiment of the present invention. And an image display area D and an image non-display area C are respectively arranged on two sides of a boundary line L of the non-full-screen image display area, and color configuration parameters of an image display area P and an image non-display area of the boundary pixels are adjusted.

Configuration information of all boundary pixels can be acquired from the first parameter list, and an image to be displayed can be processed into a shape matched with a non-full-screen display area according to the configuration information of the boundary pixels in the image display process. When the non-full-screen image is displayed, the hardware for processing the non-full-screen image display can obtain the parameters corresponding to the non-full-screen image display area through the first parameter list, and only the first parameter list occupies the corresponding memory.
By adopting the embodiment of the invention, for a display screen with any shape, the configuration parameters of the boundary pixels corresponding to the non-full screen image display area can be configured to the image display processing hardware of the mobile equipment in the mode of the first parameter list. The first parameter list for carrying the configuration parameters of the boundary pixels can be obtained by calculation outside the mobile device and configured to the mobile device, so that image display processing hardware of the mobile device does not need to perform a large amount of calculation, memory can be saved, the size of a corresponding chip in the mobile device can be reduced, and cost is reduced.
In order to facilitate better understanding and implementation of the present invention for those skilled in the art, the non-full-screen image display method is described below with reference to fig. 4 and 5 by taking the shape of the non-full-screen image display area presented on the display screen as a rounded screen as an example.
With reference to fig. 4 and 5, the boundary line L of the circular bead screen includes four corners, each of which is a quarter circular arc L1 with a radius R, the left upper region C of the circular arc L1 does not display an image, the color configuration parameters of the pixels in the region C are set to be black, the right lower region D of the circular arc L1 needs to normally display an image, and the color configuration parameters of the pixels in the region D are not adjusted. A certain transition region between the arc L1 and the image display region D needs to be anti-jagged, that is, a certain processing needs to be performed on the image display region of the boundary pixel. For example, a certain transition region between the circular arc L1 and the image display region D is processed by anti-aliasing to adjust the color configuration parameters of the boundary pixels according to the gains of the boundary pixels. Due to the fact that the pixels are rectangular, transition of an image display area and a non-image display area can be smooth and gentle through anti-aliasing processing of boundary pixels.
In one embodiment of the present invention, the image data is processed line by line, and the image is RGB three-channel, wherein R, G, B refers to the three primary colors of the image, R stands for red, G stands for green, and B stands for blue.
Since the pixel is a rectangle, the coordinate of the upper left corner of the pixel is taken as the pixel coordinate. Due to the symmetry of the rounded screen, the arc of the top left corner 1/4 is illustrated in conjunction with FIG. 5.
The boundary shape is 1/4 circular arcs with (R, R) as the center and R as the radius. The pixel (i, j) is the jth pixel on the ith row of the image, and the pixel (i +1, j +1) is the jth +1 pixel on the ith +1 row of the image, wherein the pixel (0, 0) is the coordinate of the starting point pixel.
Whether the pixel (i, j) is crossed by the boundary line is judged by the following formula (1) and formula (2). When the pixel (i, j) satisfies the following equations (1) and (2), the pixel (i, j) is crossed by the boundary line.
(R-i) 2 +(R-j) 2 ＞R 2 ； (1)
(R-i-1) 2 +(R-j-1) 2 ＜R 2 ； (2)
The gain of the pixel (i, j) is the area ratio of the region p to the lower right of the circular arc line in the pixel to the total pixel.
And traversing the 0 th to the R-1 th lines of the image, and finding out the positions of all boundary pixels and corresponding gain values.
In the embodiment of the invention, the image data processing adopts line-by-line processing, and all boundary pixels are partitioned into blocks according to lines. As can be seen from the geometrical relationship, the boundary pixels of the same row are necessarily adjacent.
For example, the boundary pixels of the ith row are Xi pixels from the Mi pixel, and the corresponding Gain values are (Gain1, Gain2, …, Gain Xi). Using a quadratic polynomial ax 2 + bx + c gains Gain1, Gain2, … for each boundary pixelGainxi was fitted. The binomial fit may be achieved by a least squares method. Only three parameters (a, b and c) of the quadratic polynomial, the first pixel position Mi and 5 parameters in total of the number Xi of the boundary pixels are needed to contain the configuration information of all the boundary pixels in the ith row.
Through the fix-point and shift operations, fixed bit widths are respectively given to the 5 parameters, the 5 parameters can be integrated into one fixed bit width parameter, and the obtained fixed bit width parameter is also the parameter block corresponding to the ith row. And sequentially compressing 5 parameters corresponding to each line to obtain a parameter block corresponding to each line, and obtaining R parameter blocks in total from 0 to R-1, thereby obtaining a first parameter list. The first parameter list includes configuration information of all boundary pixels of a non-full screen image display area. This first parameter list may be configured as configuration information to hardware for image display processing. The first parameter list is generated according to a fixed format, so that hardware reading and implementation are facilitated, and the friendliness of hardware for image display processing can be improved.
In the calculation process of the hardware of the image display processing, when the ith row of the image is processed, the ith parameter of the parameter list is read, and then the parameters (a, b, c, Mi, Xi) of the ith row can be obtained through bit operation. If R, G, B values of 0 to Mi-1 th pixels are set to 0 for 0 to Mi-1 th pixels in the ith row, the colors of all the 0 to Mi-1 th pixels are black, and no image content is displayed. For Mi-Mi + Xi-1 boundary pixels in the boundary line L1 area, gains of corresponding boundary pixels are obtained through quadratic polynomials respectively, and product operation is carried out on the gains of the boundary pixels and R, G, B values of the corresponding boundary pixels respectively to obtain R, G, B values of the adjusted boundary pixels. After the R, G, B value of the boundary pixel is adjusted, the boundary pixel will generate a smooth transition zone from black to normal display. The R, G, B for the pixels in the other image display region D are not adjusted, and the image content can be displayed normally.
It will be appreciated that the color of the image may also be adjusted by adjusting the brightness as well as the color of the image using LAB as color configuration parameters for the pixels. In practical applications, other color configuration parameters may also be adopted, which are not described herein again.
According to the embodiment of the invention, a large amount of calculation can be finished under the condition of leaving outside the mobile equipment, and the first parameter list is obtained. The hardware needing image display processing is very simple in calculation, after the configured first parameter list is read, each pixel can be completed only by a plurality of multipliers, adders and bits, the hardware needing image display processing is simple in calculation, and the hardware needing image display processing is high in friendliness. For example, in some embodiments, only one or more parameters set for each row are required, and a row memory buffer (buffer) is not required, so that less memory resources are occupied.
At present, the capacity of some irregular non-rectangular screens is low, the screen shapes required by different manufacturers are different, and the cost for customizing the non-rectangular screens is high.
In order to facilitate better understanding and implementation of the embodiments of the present invention for those skilled in the art, the embodiments of the present invention also provide an image display device.
