Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
For ease of illustration, embodiments of the present invention are illustratively described in terms of visual devices comprising a display screen, and those skilled in the art will appreciate that embodiments of the present invention are equally applicable to other devices, such as handheld devices, vehicle mount devices, wearable devices, computing devices, and various forms of User Equipment (UE), mobile Stations (MS), terminals, terminal devices (Terminal Equipment), etc.
The embodiment of the invention provides a picture display method. As shown in fig. 4, the method for displaying a picture provided by the embodiment of the invention includes the following steps:
In the embodiment of the invention, the picture frame pattern and the picture pattern of the artistic picture are arranged on different display layers for display, the picture frame pattern is displayed on an OSD layer, and the picture pattern is displayed on a video layer. The picture frame pattern comprises a picture frame display area, a white-reserving area and a picture display area, wherein the white-reserving area is an area between the picture frame display area and the picture display area. And determining a first display area of the picture frame pattern in the OSD layer, and determining a second display area of the picture pattern in the video layer according to the first display area, so that the projection of the first display area in the video layer is positioned in the second display area. The picture display area is set to be transparent, and the picture frame display area and the white-remaining area are set to be opaque, so that when the picture frame pattern is displayed on the OSD layer and the picture pattern is displayed on the video layer, the picture pattern can be displayed through the picture display area of the picture frame pattern. According to the embodiment of the invention, the blank area in the picture frame pattern can be set to be equal in width at the periphery, so that the aesthetic appearance of the artistic picture display is ensured. Because the projection of the first display area on the video layer is positioned in the second display area, the picture pattern fills up the picture display area of the picture frame pattern, and the picture pattern and other length-width ratios can be stretched, so that the picture pattern is ensured not to be deformed and distorted.
In step 401 described above, setting the picture display region to be transparent may include two ways:
1. the picture display area has pixel data. The attributes of one pixel data include RGB (color mode) and Alpha values of the pixel data. Wherein Alpha value indicates transparency and translucency of one pixel data, and is generally between 0 and 1, 0 is opaque, and 1 is transparent. The embodiment of the invention can set the Alpha value of the pixel data in the picture display area to be 1.
2. There is no pixel data in the picture display area. Thus, when the picture frame pattern is drawn on the OSD layer, the picture display area is completely transparent. When the picture frame pattern is drawn on the OSD layer, the picture display area has no pixel data, so that the calculated amount and the memory of the system are saved, and the drawing speed is improved.
In the embodiment of the invention, the picture frame patterns and the picture patterns are displayed in a layered manner, and the picture patterns are displayed on the video layer, so that the picture quality of the picture patterns can be independently adjusted to achieve the optimal display effect. The picture frame patterns of the OSD layer can be independently switched, when the picture patterns are unchanged, the display of the picture patterns is not required to be updated due to the switching of the picture frame patterns, and the calculation and drawing processes are reduced.
In the embodiment of the invention, the position and the area of the picture pattern on the video layer are determined according to the position and the area of the picture display area of the picture frame pattern. The determining, according to the first display area, a second display area of the picture pattern in the video layer includes:
performing length-width equal-ratio scaling on the picture pattern, so that the area of the picture pattern is not smaller than the area of the picture display area;
and determining the second display area according to the areas of the first display area and the picture pattern.
In order to achieve the purpose of changing the area of the picture pattern without distortion and deformation, the picture pattern is scaled in length-width equal ratio in the embodiment of the invention, so that the area of the picture pattern is not smaller than the area of the picture display area. And then, determining a second display area according to the areas of the first display area and the picture pattern, so that when the picture pattern and the picture frame pattern are displayed in a superimposed manner, the picture pattern can fill the picture display area and is displayed through the picture display area of the picture frame pattern.
Further, the specific position of the second display area may be determined according to the content of the picture pattern and the specific position of the first display area. For example, the position of the picture pattern is set to overlap with the position of the picture display region, that is, the coordinates of the upper left corner of the picture pattern are the same as those of the upper left corner of the picture display region, as shown in fig. 5, and the frame of the broken line in fig. 5 is a portion where the picture pattern is hidden by the picture frame pattern.
Preferably, the determining the second display area according to the areas of the first display area and the picture pattern includes:
determining a center of the first display area as a center of the second display area;
and determining the second display area according to the center of the second display area and the area of the picture pattern.
The content in the picture pattern is generally presented in the middle position of the picture, so that in order to achieve a better display effect, the embodiment of the invention overlaps the center of the first display area with the center of the second display area, and then the second display area is determined according to the center of the second display area and the area of the picture pattern.
The display mode of the picture patterns is that the picture patterns are displayed through the picture display area which is set to be transparent, and the areas outside the picture display area are shielded by the areas which are set to be opaque in the picture frame patterns, so that the display effect that the picture patterns are cut out is achieved. The picture pattern can also be cut, and the blocked part in the picture pattern is cut. In order to ensure the integrity of the picture, the embodiment of the invention only performs shielding treatment, so that when the picture display area of the picture frame pattern changes, the picture pattern of the video layer still stores complete picture data, the picture is not cut, the new picture display area can be re-adapted only through stretching and scaling operation, partial data of the picture pattern is not lost because of cutting operation, and the picture pattern is not required to be re-decoded to obtain complete data. Thus, when the picture pattern is unchanged, only the picture pattern of the OSD layer is updated when the picture pattern is switched, and the picture pattern of the video layer is not required to be updated, so that the calculation amount of a CPU (central processing unit ) can be reduced, and the operation of updating the screen by the GPU (graphics processor, graphics Processing Unit) can be reduced.
In the embodiment of the invention, the area of the picture pattern is not smaller than the area of the picture display area, so that the picture pattern completely fills the picture display area, and therefore, the length-width equal ratio of the picture pattern can be scaled to a length of the picture pattern larger than the length of the picture display area, and the width of the picture pattern is larger than the width of the picture display area, as shown in fig. 6. In fig. 6, the second display area of the picture pattern is an area outlined by a dashed line 601, and the first display area of the picture display area is an area outlined by a solid line 602, and it can be seen that the length of the first display area is greater than the length of the second display area, and the width of the first display area is greater than the width of the second display area. In order to present more content in the picture display area and also to reduce the workload of calculation and drawing, in the embodiment of the present invention, the length of the first display area is set to be the same as the length of the second display area, or the width of the first display area is set to be the same as the width of the second display area, that is, the area of the first display area is minimized on the premise of ensuring that the picture pattern can be filled in the picture display area.
The comparison of the picture pattern with the picture display region may include three cases, i.e., the aspect ratio of the picture pattern is equal to the aspect ratio of the picture display region, the aspect ratio of the picture pattern is smaller than the aspect ratio of the picture display region, and the aspect ratio of the picture pattern is larger than the aspect ratio of the picture display region.
These three cases are described below, respectively.

and if the length-width ratio of the picture pattern is equal to the length-width ratio of the picture display area, carrying out length-width equal-ratio scaling on the picture pattern so that the area of the picture pattern is equal to the area of the picture display area.
If the aspect ratio of the picture pattern is equal to the aspect ratio of the picture display region, the picture pattern may not be blocked by the picture frame pattern of the OSD layer after the picture pattern is stretched, and the area of the picture pattern is equal to the area of the picture display region, i.e., the picture pattern coincides with the picture display region of the picture frame pattern, as shown in fig. 7.
If the aspect ratio of the picture pattern is not equal to the aspect ratio of the picture display region, the picture pattern of the video layer needs to be partially blocked by the picture frame pattern of the OSD layer, and the following two cases are also classified.
And secondly, scaling the length-width equal ratio of the picture pattern so that the area of the picture pattern is not smaller than the area of the picture display area, wherein the scaling comprises the following steps:
and if the length-width ratio of the picture pattern is smaller than that of the picture display area, carrying out length-width equal-ratio scaling on the picture pattern so that the length of the picture pattern is equal to that of the picture display area.
In the second display mode, as shown in fig. 8, the length of the picture pattern is scaled in equal ratio until the length of the picture pattern is equal to the length of the picture display area, and the width of the picture pattern is larger than the width of the picture display area. If the center of the picture pattern is set to coincide with the center of the picture display area, the area of the picture pattern blocked by the picture frame pattern is an area 801 surrounded by a dotted line and a solid line in fig. 8.
In a third aspect, the scaling the length-width ratio of the picture pattern to make the area of the picture pattern not smaller than the area of the picture display area includes:
and if the length-width ratio of the picture pattern is larger than that of the picture display area, carrying out length-width equal-ratio scaling on the picture pattern so that the width of the picture pattern is equal to that of the picture display area.
In the third display mode, as shown in fig. 9, the length and width of the picture pattern are scaled in equal ratio until the width of the picture pattern is equal to the width of the picture display area, and the length of the picture pattern is greater than the length of the picture display area. If the center of the picture pattern is set to coincide with the center of the picture display area, the area of the picture pattern blocked by the picture frame pattern is an area 901 surrounded by a dotted line and a solid line in fig. 9.
