Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
An image display method and apparatus according to embodiments of the present application are described below with reference to the accompanying drawings. The image display method of the embodiment of the application is applied to any image containing a background image.
In order to solve the technical problem of image distortion caused by adjusting the image resolution to the display resolution in the background art, the application provides a personalized adaptation strategy for an image, ensures that the image is not distorted and achieves the optimal display effect.
Specifically, fig. 2 is a flowchart of an image display method according to an embodiment of the present application. As shown in fig. 2, the method includes:
It should be noted that the resolution is generally described by the parameter "aspect ratio", where the aspect ratio is understood to be the ratio of the resolution of the long side of the image or display area divided by the resolution of the short side, and the aspect ratio of many mobile phones is currently 16:9, the resolution is 750 x 1334, 1080 x 1920,1280 x 720, and the like. When the aspect ratios are uniform, the image can fit the display screen display even if the resolutions are different. As shown in fig. 3-1, the display area in this embodiment may be the entire display screen, or may be a partial area in the display screen for displaying the image as shown in fig. 3-2, which is not limited herein.
Specifically, the image resolution of the image and the display resolution of the display area are acquired, and whether the image resolution and the display resolution are the same is judged to determine whether the two resolutions are matched. Of course, it is also possible to acquire an aspect ratio corresponding to the image resolution and an aspect ratio corresponding to the display resolution, and determine whether the resolutions match by determining whether the aspect ratios of the two match.
And 102, if the image resolution and the display resolution are not matched, acquiring a transverse resolution ratio and a longitudinal resolution ratio of the image resolution and the display resolution.
Specifically, if the image resolution and the display resolution are not matched, for example, the aspect ratio of the two is inconsistent, or the aspect ratio difference is larger, the image and the display area are considered to be not suitable, so that a transverse resolution ratio and a longitudinal resolution ratio of the image resolution and the display resolution are obtained, wherein the transverse resolution ratio refers to a ratio of a length value of the image and the display area in the transverse direction, the longitudinal resolution ratio refers to a ratio of a width of the image and the display area in the longitudinal direction, the transverse resolution ratio can be obtained by calculating a ratio of the transverse resolution of the image and the transverse resolution of the display area, and the longitudinal resolution ratio can be obtained by calculating a ratio of the longitudinal resolution of the image and the longitudinal resolution of the display area.
For example, when the image resolution is 750 x 1334 and the display resolution is 1080 x 2240, the ratio of the horizontal resolution is 1080/750 equal to about 1.44 and the ratio of the vertical resolution is 2240/1334 equal to about 1.679.
In one embodiment of the present application, if the image resolution and the display resolution match, the image is displayed directly in the display area.
Specifically, a preset image parameter of the image is acquired, so that the image is displayed in a matching way based on the preset image parameter as a reference.
Under different application scenarios, the preset image parameters are different, and examples are as follows:
example one:
in this example, the image element included in the image is identified, where the image element includes entities such as a subject of the image and a person of the image, and in the actual implementation process, the image element may be identified based on the image feature, and further, the image complexity of the image is calculated according to the image element, and the image complexity is used as a preset image parameter.
In the present embodiment, the image complexity may be determined based on one or more of the number of image elements, the color richness of the image elements, the distribution density of the image elements, and the like.
Example two:
in this example, the content type contained in the image, such as a person class, a landscape class, or a scene class, is identified as a preset image parameter.
Example three:
in this example, the content contained in the image is identified, and the associated information corresponding to the content is acquired, and the associated information may be information related to the content contained in the image or recommended information associated with the content. For example, when the content included in the image is a star, the corresponding preset image parameter may be surrounding product information of the star.
And 104, determining a display strategy of the image according to the preset image parameters, the transverse resolution ratio and the longitudinal resolution ratio, and controlling the image to be displayed on a display area according to the display strategy.
Specifically, a display strategy of the image is determined according to preset image parameters, a transverse resolution ratio and a longitudinal resolution ratio, the display strategy integrates the transverse resolution ratio and the longitudinal resolution ratio, and the preset image parameters are considered, so that the display effect of controlling the image to be displayed on a display area according to the display strategy is ensured.
It should be noted that, in different application scenarios, the display strategies of the images are determined according to preset image parameters, a transverse resolution ratio and a longitudinal resolution ratio, and the modes of controlling the images to be displayed on the display areas according to the display strategies are different, which are illustrated as follows:
example one:
when the preset image parameter includes an image complexity, determining a maximum value and a minimum value of the transverse resolution ratio and the longitudinal resolution ratio when the image complexity is greater than a preset threshold, that is, distinguishing a relatively larger value and a smaller value of the transverse resolution ratio and the longitudinal resolution ratio. For example, when the ratio of the horizontal resolution is 1.44 and the vertical resolution is 1.679, 1.679 is the maximum value and 1.44 is the minimum value.
Further, judging whether the image elements contained in the edge area of the image meet preset filtering conditions, for example, whether the image elements at the edge of the image are important and can not be filtered, and if the image elements are not important, considering that the preset filtering conditions are met; for example, if the definition of the image element at the image edge is lower, if the definition is lower, the preset filtering condition is considered to be satisfied; for example, if the number of image elements at the image edge is smaller, if the number of image elements is smaller, the preset filtering condition is considered to be satisfied; for example, if the image elements included in the edge region of the image are the same elements as those of the non-image edge region, the preset filtering condition is considered to be satisfied.
It should be understood that the edge area of the image in this example can be understood as an area that exceeds the display area when the image is enlarged according to the maximum value.
If the filtering condition is met, adjusting the horizontal display resolution and the vertical display resolution of the image according to the maximum value, displaying the adjusted image on the display area, and continuing taking the above embodiment as an example, for example, the image elements at the edge of the image are not important and can be filtered; for example, the image element definition of the image edge is low; for example, the number of image elements at the image edge is small; for another example, the image elements included in the edge region of the image are the same as those of the non-image edge region.
For example, when the maximum value is 1.679 and the image resolution is 750×1334, 750×1.679=1259 may be used as a basis for adjusting the lateral dimension of the image, and 1334×1.679=2240 may be used as a basis for adjusting the longitudinal dimension.
In this example, if the preset filtering condition is not satisfied, the landscape display resolution and the portrait display resolution of the image are adjusted according to the minimum value, and when the minimum value is 1.44, 750×1.44=1080 may be used as a basis for adjusting the landscape size of the image, and 1334×1.44=1920 may be used as a basis for adjusting the portrait size.
At this time, since the vertical height corresponding to the resolution of the display area is 2240 and the adapted height is 1920, there is a 320-pixel defect, as shown in fig. 4-1, the effect on the procedure is that black edges appear up and down, and at this time, a filling image needs to be acquired to fill the black edge area based on the filling image. Further, the adjusted image is displayed on the display area, and the filled image is displayed in an unfilled area between the display area and the adjusted image.
As a possible implementation manner, the filling image corresponding to the image is determined according to a preset corresponding relation, that is, the filling image corresponding to the image is determined in advance according to the personalized requirement of the user, and the filling image is displayed in the black area.
As another possible implementation manner, as shown in fig. 4-2, the image is enlarged according to the maximum value, the enlarged image is subjected to blurring processing, a filling image is obtained, and the filling image is superimposed under the adjusted image for display, however, in this embodiment, the image may be subjected to blurring processing first and then the image subjected to blurring processing is enlarged according to the maximum value during display, and then the filling image is superimposed under the adjusted image for display.
In this example, when the image complexity is less than or equal to the preset threshold, it indicates that the image complexity is low, for example, it may be a solid-color image, etc., a maximum value of the lateral resolution ratio and the longitudinal resolution ratio is determined, and then the lateral display resolution and the longitudinal display resolution of the image are adjusted according to the maximum value, and the adjusted image is displayed on the display area.
Example two:
in this example, if the preset image parameter is the associated information of the image content, as shown in fig. 4-3, a light-colored solid background image is displayed in a black area, and the associated information is displayed on the background image, where the associated information may be displayed in a bullet screen form, a text frame form, or the like, and when the user clicks the corresponding associated information, the associated information may be displayed in the solid background image.
In this example, the associated information may also be displayed in a mobile form, such as continuously swimming, etc., in order to increase the interest of the display.
In one embodiment of the present application, to view the effect of the adaptation, different types of images may also be switched to perform the adaptation effect switching, so as to view the adaptation effect.
In summary, according to the image display method of the embodiment of the application, the image resolution of the image and the display resolution of the display area are obtained, whether the image resolution is matched with the display resolution is judged, if the image resolution is not matched with the display resolution, the transverse resolution ratio and the longitudinal resolution ratio of the image resolution and the display resolution are obtained, further, the preset image parameters of the image are obtained, further, the display strategy of the image is determined according to the preset image parameters, the transverse resolution ratio and the longitudinal resolution ratio, and the image is controlled to be displayed on the display area according to the display strategy. Therefore, the problem of display distortion caused by inconsistent display resolutions of the image and the display area is avoided, and the display effect of the image is optimized.
