Detailed Description
Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the disclosure are for illustration purposes only and are not intended to limit the scope of the disclosure.
It should be understood that the various steps recited in the method embodiments of the present disclosure may be performed in a different order, and/or performed in parallel. Moreover, method embodiments may include additional steps and/or omit performing the illustrated steps. The scope of the present disclosure is not limited in this respect.
The term "include" and variations thereof as used herein are open-ended, i.e., "including but not limited to". The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.
It is noted that references to "a", "an", and "the" modifications in this disclosure are intended to be illustrative rather than limiting, and that those skilled in the art will recognize that "one or more" may be used unless the context clearly dictates otherwise.
At present, when pictures are loaded from a network under the condition of weak network or no network, most terminal applications display an default picture or blank picture. For example, the default picture is a picture in which a word such as "the picture cannot be displayed" is displayed. For example, as shown in fig. 1, is a default picture type. Or some directly display a blank. Such user experience is not good and needs to be improved.
In the present disclosure, in order to improve the above-described problems. When the server receives the picture resource and allocates an address for the picture resource, the color value of part of pixel points of the picture is combined in a Uniform Resource Locator (URL) of the picture, and when the terminal application accesses the uniform resource holder of the picture, the color value in the uniform resource holder can be used for rendering the fuzzy picture. Because the fuzzy picture is rendered by using the color values of the partial pixel points of the corresponding picture, the fuzzy picture is similar to the corresponding picture in outline, and the user experience can be improved relative to a default picture or a blank picture.
It should be understood that the server of the present disclosure may include the server of the terminal itself, and may also include a cloud server, etc. It should also be understood that the terminal in the present disclosure may include, but is not limited to, mobile terminal devices such as a mobile phone, a smart phone, a notebook computer, a PDA (personal digital assistant), a PAD (tablet computer), a PMP (portable multimedia player), a navigation device, a vehicle-mounted terminal device, a vehicle-mounted display terminal, a vehicle-mounted electronic rearview mirror, etc., and fixed terminal devices such as a digital TV, a desktop computer, etc.
As shown in fig. 2, an embodiment of the present disclosure provides a method for displaying a picture, including step S101, selecting a plurality of pixel points of the picture. In some embodiments, multiple pixel points may be uniformly selected from the picture. For example, a picture has 10000 pixels, and 100 pixels can be uniformly selected from a pixel array of the picture. It will be appreciated that the more selective the pixel points, the more advantageous the rendering sharpness of the picture is, but the more data to be processed, thus placing a burden on the data processing. Specifically, the setting may be performed as needed, and generally, 50 to 100 pixel points may be selected from the picture. By uniformly selecting the pixel points, the positions of the picture can be used for subsequent rendering as many as possible, so that the overall picture of the picture can be reflected better.
The method of the present disclosure further includes step S102, obtaining color values of the plurality of pixel points. In some embodiments, the pixels of the picture may be substantially reflected by colors, and the picture is composed by a combination of colors on different pixels. Therefore, the method and the device are used for rendering and displaying the subsequent pictures through the colors of the pixel points. The color values of the pixels can be represented in different forms, for example, a hexadecimal color code can be used for representation.
The method of the present disclosure further includes step S103, combining the color values of the plurality of pixel points into a Uniform Resource Locator (URL) of the picture. In some embodiments, the uniform resource locator is comprised of multiple parts, including, for example, protocol, host, port, path, and the like. In addition, optional parameter data and the like may be included in the uniform resource locator. And combining the color values of the plurality of pixel points into corresponding positions of a Uniform Resource Locator (URL) of the picture according to the format of the corresponding URL.
According to the embodiment of the disclosure, the color values of the partial pixel points of the picture are combined into the uniform resource occupier of the picture, and when the terminal application accesses the uniform resource occupier of the picture, the color values in the uniform resource occupier can be used for rendering the fuzzy picture. Because the fuzzy picture is rendered by using the color values of the partial pixel points of the corresponding picture, the fuzzy picture is similar to the corresponding picture in outline, and the user experience can be improved relative to a default picture or a blank picture. In some embodiments, when the client accesses the URL of the picture, different algorithms like gaussian blur can be used to disperse the colors to simulate a real picture.
As described above, the more pixel points are selected, the more advantageous the rendering of the blurred picture is. However, the more pixels selected, the more data is incorporated into the URL, and the burden is imposed on the URL. Therefore, the color values of more pixel points on the URL band which is as short as possible are expected to be used, so that the effect of rendering the picture can be better ensured, and the burden on the URL can be reduced.
In some embodiments, lossy compression is applied to the color values of the pixel points to reduce the length of data that needs to be incorporated into the URL. In general, blurred pictures do not require accurate pixel values, and therefore, this approach is feasible. In some embodiments, the color value represented by six bits is compressed into three bits, e.g., one color value of 3F51B5, which may be compressed into 3355 BB. In this manner, the length of data that needs to be incorporated into the URL is reduced.
In some embodiments, the data length after the above compression is used is still unsatisfactory. In this case, the compressed color values may be converted into ASCII code for representation. The three-bit 16-ary color values described above have 16 × 16 — 4096 colors, and in the ASCII code, there are approximately 90 or more colors that can be used in the URL format, so that the two-bit ASCII code can represent at least 90 × 90 — 8100 colors, and can cover all colors, i.e., the two-bit ASCII code can represent three-bit 16-ary color values, thereby further reducing the length of data that needs to be incorporated into the URL.
And finally, carrying the color values of the sampled horizontal and vertical pixel points in the URL according to the agreed format. Therefore, the client application can read out the color values of the corresponding pixel points of the picture from the URL in sequence to render a fuzzy picture.
Since colors in a picture are more sensitive to a user, in some embodiments, selecting a plurality of pixel points of a picture may include determining a density of sampling of the pixel points according to vividness of the colors of the pixel points in the picture. The density of the samples can be increased at the position where the color is more vivid, and can be appropriately decreased at the position where the color is lighter. Since pixel points at darker locations are more favorable for rendering the picture than at lighter locations.
The embodiment of the present disclosure also provides an apparatus 300 for displaying a picture, which includes a selection module 301, a color value obtaining module 302, and a color value adding module 303. The selection module 301 is configured to select a plurality of pixel points of the picture. The color value obtaining module 302 is configured to obtain color values of a plurality of pixel points. The color value adding module 303 is configured to combine the color values of the plurality of pixel points into the uniform resource locator of the picture.
In addition, the present disclosure also provides a terminal, including: at least one memory and at least one processor; the memory is used for storing program codes, and the processor is used for calling the program codes stored by the memory to execute the method for displaying the pictures.
In addition, the present disclosure also provides a computer storage medium storing program codes for executing the above method for picture presentation.
In some embodiments, by combining the color values of the partial pixel points of the picture into the uniform resource occupier of the picture, when the terminal application accesses the uniform resource occupier of the picture, the color values in the uniform resource occupier can be used for rendering the blurred picture. Because the fuzzy picture is rendered by using the color values of the partial pixel points of the corresponding picture, the fuzzy picture is similar to the corresponding picture in outline, and the user experience can be improved relative to a default picture or a blank picture. In addition, by compressing the color values and/or converting the color values into ASCII code form, the length of data that needs to be incorporated into the URL is greatly reduced, reducing the burden on the URL. Therefore, the embodiment of the disclosure can display a fuzzy placeholder map under the condition of no network or weak network, and improves the user experience.
