The following description is an embodiment of the claimed invention, and other embodiments related to the claims not specifically described also fall within the scope of the claims.
FIG. 1 illustrates a flow diagram of a power-saving page rendering method in accordance with the present invention.
As shown in fig. 1, a power-saving page rendering method is provided, which may include: synthesizing the reading background and the reading resource into an image S1; the image is acquired for presentation as a display page S2.
The power-saving page presenting method can be applied to page presentation in various electronic devices or reading software, such as page presentation of an electronic book. According to the technical scheme of the invention, the content information to be presented can be overlaid in advance and combined into a whole, for example, the page content to be presented in an electronic document such as an electronic book, including a reading background and a reading resource, is combined into a whole image. The process can be carried out in other devices or areas except the display card and the display screen, such as a memory, a cache, a processor and the like, and the power consumption caused by the processing of the display card can be reduced. Then, the information of the whole image is obtained and can be directly presented. For example, the display screen or the display card acquires the information of the image, and the image can be directly presented only by processing once, so that the processing frequency of the display card is reduced. The images may be stored after being synthesized or may be acquired directly after being synthesized. The operation of synthesizing the reading background and the reading resource into the image S1 may be to synthesize only the current page to be displayed or the page adjacent to the current page, or may be to process and store all the pages to be presented of, for example, an electronic book, so as to obtain the pages directly afterwards, thereby further increasing the display speed of each page.
The display card can be used for converting information to be displayed and providing signals for a display connected with the display card so as to control the display to be correctly displayed, and the display card can comprise an independent display card, an integrated display card, a display card chip and the like. The display can be a display screen of the electronic device or the like which can realize human-computer interaction with a user.
The reading background may include at least one of a solid background, a gradient background, a pattern background, a picture background, and the like. The reading background, that is, the background of the page to be displayed, may be a default setting, or may be a setting actively set by the user according to a preference, for example, the user may set a photo or a favorite picture of the user as the background of the user, or may set the setting differently according to a presentation mode, for example, daytime reading or nighttime reading.
The reading resources may include at least one of text, numbers, graphics, pictures, video, animation, audio, and the like. The reading resource is the substance content to be read by the user. The reading resource can be typeset according to the size and font size of the display screen, the content of the electronic document and the like, namely the content of characters, numbers, pictures, animations and the like of each page and the information of the position and the like are arranged.
In the present invention, the image may refer to all presentable pictures with visual effects, and may include static pictures, such as colors, characters, pictures, etc., or dynamic pictures, such as videos, audios, animations, etc.
According to an embodiment of the present invention, the obtaining the image to be presented as a display page S2 may further include obtaining the image and rendering the image to be presented as a display page. And obtaining the information of the image, and rendering the image to be displayed, so that the image can be presented to a user with a better effect, and the user experience is improved. The rendering may include not only image processing for rendering the image, but also further processing for rendering effects, such as lighting effects, shadow effects, stereo effects, etc., on the image.
FIG. 2 is a diagram illustrating a page rendering embodiment for compositing images in memory according to the present invention.
According to an embodiment of the present invention, the synthesizing of the reading background and the reading resource into the image S1 may include synthesizing the reading background and the reading resource into the image in a memory. As shown in fig. 2, the reading background and the reading resource to be presented in each page may be synthesized into an image 210 in the memory, and then the display card may directly obtain the image 210 from the memory, and may convert information of the image 210 into a signal that can be recognized by the display screen, so as to present the signal as a display page on the display screen. Multiple interactions between the display card and the memory are avoided when each page is presented, and therefore the presentation speed of the displayed page is improved. And each page can be presented on the display card only by rendering once, so that the use frequency of the display card is reduced, and the loss of the electric quantity of the battery is reduced.
FIG. 3 is a schematic diagram illustrating an embodiment of a composite image according to the present invention.
As shown in fig. 3, the method for synthesizing the image 210 may include: create canvas 211; populating the reading background 212 on the canvas 211; adding the reading resource 213 on the reading background 212; synthesizing the reading background 212 and the reading resource 213 on the canvas 211 into the image 210.
The image 210 synthesis method may include first creating a canvas 211, for example, when synthesizing the image 210 in a memory, creating the canvas 211 in the memory, where the canvas 211 may have no ground color and no content, may be a virtual bottom plate or a layer, and may also be created according to a size of a display screen, for example, the size of the canvas is the same as the size of the display screen, and the size includes at least a length and a width, so that the image synthesized on the canvas subsequently may be just presented on the display screen, and neither a surrounding gap due to being smaller than the display screen nor a loss of presented content due to being larger than the display screen may be caused, thereby achieving an optimal presentation effect.
Then, the reading background 212 may be filled on the canvas 211, and the filling may refer to that the canvas 211 is entirely filled so that the size of the reading background 212 is the same as the size of the canvas 211. For example, the desired reading background is sweetened bean paste green, which may be rendered for all locations on the canvas 211.
Then, the reading resources 213 are added on the reading background 212. The reading resource 213 that has been typeset is printed on the reading background 212 or positioned on the upper layer of the reading background 212 to be clearly shown.
Finally, the reading background 212 and the reading resource 213 are combined into an integral image 210, or the canvas 211, the reading background 212 and the reading resource 213 are combined into an integral image 210, and the integral image 210 is stored in a memory or a cache, or is directly acquired by a display card.
FIG. 4 illustrates a block diagram of a power-saving page rendering device in accordance with the present invention.
As shown in fig. 4, there is provided a power-saving page presentation apparatus including: a first device M410 for synthesizing the reading background and the reading resource into an image; and a second device M420, configured to acquire the image, so as to present the image as a display page.
