The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
In an exemplary embodiment of the present disclosure, a method for displaying an image is provided, and the method is applied to a terminal, where the terminal includes an electronic device with a camera function, such as a smart phone, a tablet, and the like. Fig. 1 is a flowchart illustrating a method of displaying an image according to an exemplary embodiment, and as shown in fig. 1, the method of displaying an image includes the steps of:
step S101: the method comprises the steps that an application of a receiving terminal calls a camera to obtain an image acquisition instruction of an image according to a preset preview size;
step S102: determining whether the preset preview size needs to be adjusted according to the preset preview size and the display size of the application, wherein the display size comprises the size of a display area of the application;
step S103: if yes, adjusting a preset preview size, and acquiring an image according to the adjusted preview size;
step S104: the acquired image is displayed in the application according to the display size.
In an exemplary embodiment of the present disclosure, in order to overcome the problem that in the related art, due to the negligence of a software developer, when a camera function of a terminal is invoked, a preset preview size and a display size of an image display area are greatly different, so that an image frame obtained by displaying is stretched or compressed, a display method of an image is provided. Receiving an image acquisition instruction of an application calling camera of the terminal to acquire an image according to a preset preview size; determining whether the preset preview size needs to be adjusted according to the preset preview size and the display size of the display area of the application; if yes, adjusting a preset preview size, and acquiring an image according to the adjusted preview size; the acquired image is displayed in the application according to the display size. The method comprises the steps of presetting a preview size, wherein the preset preview size comprises a preview size obtained by applying an image set to a camera; the display size includes a size of a display area of the application setting.
When the application of the terminal needs to use the scene of the camera, for example, when the functions of sweeping, photographing and the like are used, the camera of the terminal system can be called through the setting interface, and meanwhile, a display area is set in the application so as to display the preview image acquired through the camera. When the camera is called, a preset preview size needs to be set to the camera in advance. When the camera receives a call instruction, acquiring an image according to a preset preview size set by the application, returning the acquired image data to the application, and displaying the image acquired by the camera in a display area set by the application according to the returned image data of the camera by the application. When the preset preview size of the image acquired by the camera set by the application is larger than the display size of the display area of the application, the size of the acquired image is inconsistent with the size of the display area, which causes the problem of stretching or compressing the image picture, for example, when the preset preview size is 13.2mm×8.8mm and the display size is 10mm×8mm, the length and width of the image acquired by the camera are larger than the length and width of the display area, so that the acquired image can be compressed during display, so that the acquired image can be displayed in the display area of the application.
Therefore, when an image acquisition instruction of an application call camera of the terminal for acquiring an image according to a preset preview size is received, the terminal system acquires and stores the display size of the display area of the application set by the application, and simultaneously acquires the preset preview size of the application for acquiring the image set by the application to the camera, and determines whether the preset preview size needs to be adjusted according to the preset preview size and the display size of the display area of the application, so that the preview size is matched with the display size.
When it is determined that the preset preview size needs to be adjusted, the preview size is adjusted, and an image is acquired according to the adjusted preview size, where the adjustment of the preview size may be any rule capable of adjusting the preset preview size to a preview size that is smaller than the display size. After the application receives the image returned by the camera, the acquired image is displayed in a display area in the application according to the display size, the image acquired according to the adjusted preview size has smaller phase difference with the display size, and when the image is displayed in the application according to the display size, the phenomenon that the image is stretched or compressed greatly does not occur.
In an exemplary embodiment of the present disclosure, when an application of a terminal calls a camera, by acquiring a display size of a display area of the application, and applying the set camera to acquire a preset preview size of an image, determining whether the preset preview size needs to be adjusted according to the preset preview size and the display size, when the preset preview size needs to be adjusted, adjusting the preset preview size, and acquiring an image according to the adjusted preview size, so that when the acquired image is displayed in the display area of the application according to the display size, an image frame is not greatly stretched or compressed, and user experience is improved.
In an exemplary embodiment, determining whether the preset preview size needs to be adjusted according to the preset preview size and the display size of the application includes: it is determined whether the preset preview size needs to be adjusted according to the aspect ratio of the preset preview size and the aspect ratio of the display size.
When the preset preview size and the display size are different, if the aspect ratio is the same, the image can be scaled, and the image frame does not appear a distortion phenomenon caused by single stretching or compression of the width and height. For example, when the preset preview size is 8mm×8mm and the display size is 7mm×7mm, the aspect ratios are 1 although the sizes are different, and at this time, the image can be directly acquired according to the preset preview size, and it is determined that the preset preview size does not need to be adjusted.
Whether the preset preview size is adjusted or not is determined according to the aspect ratio of the preset preview size and the aspect ratio of the display size, and whether deformation caused by stretching or compression occurs or not can be accurately judged when the image is displayed.
In an exemplary embodiment, as shown in fig. 2, determining whether the preset preview size needs to be adjusted according to the aspect ratio of the preset preview size and the aspect ratio of the display size includes the steps of:
step S201: determining a difference value between an aspect ratio of a preset preview size and an aspect ratio of a display size;
step S202: if the difference is greater than the preset threshold, determining that the preset preview size needs to be adjusted.
After the aspect ratio of the preset preview size and the aspect ratio of the display size are determined, calculating the difference value of the preset preview size and the display size, and determining that the preset preview size needs to be adjusted when the difference value is larger than a preset threshold value. The preset threshold value can be set according to actual requirements, for example, 0.1. When the difference value is smaller than the preset threshold value, the aspect ratio of the preset preview size is not greatly different from the aspect ratio of the display size, and obvious stretching or compression phenomenon does not occur when the image is displayed according to the display size, and the preset preview size does not need to be adjusted at the moment; when the difference is larger than the preset threshold, it is indicated that the aspect ratio of the preset preview size and the aspect ratio of the display size differ greatly, and at this time, the preset preview size needs to be adjusted so that the aspect ratio of the acquired image is maximally close to the aspect ratio of the display size.
By the difference of the aspect ratio of the preset preview size and the aspect ratio of the display size, it can be more accurately determined whether the preset preview size needs to be adjusted.
In an exemplary embodiment, fig. 3 is a flowchart illustrating the adjustment of the preset preview size in step S103 according to an exemplary embodiment, as shown in fig. 3, including the steps of:
step S301: acquiring a preview size supported by a camera;
step S302: and determining the adjusted preview size according to the preview size and the display size supported by the camera.
When the preset preview size is adjusted, all the preview sizes supported by the camera or the partial preview sizes supported by the camera and having smaller difference from the display size can be obtained. According to the preview size and the display size supported by the camera, the adjusted preview size is determined, so that the adjusted preview size is matched with the display size and is also the preview size supported by the terminal, and the terminal can normally acquire the image.
In an exemplary embodiment, as shown in fig. 4, the method for determining the adjusted preview size according to the preview size and the display size supported by the camera includes the following steps:
step S401: acquiring the aspect ratio of the preview size supported by the camera, and determining the difference value between the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size;
step S402: and determining the adjusted preview size according to the difference value of the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size.
And determining a difference value of the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size according to the aspect ratio of the preview size supported by the camera, and determining the adjusted preview size according to the difference value. For example, when the preview size supported by the camera is the entire preview size supported by the camera, the difference value of the aspect ratio with the display size is sequentially calculated, and the adjusted preview size is determined according to the difference value.
The adjusted preview size can be determined by the difference between the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size, so that the adjusted preview size is more accurate.
In an exemplary embodiment, determining the adjusted preview size based on the difference in the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size includes: the preview size for which the difference between the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size is smallest is selected as the adjusted preview size.
The preview size with the smallest difference between the aspect ratio of the preview size supported by the camera and the aspect ratio of the display size is not only the preview size supported by the camera, but also the preview size with the smallest difference between the aspect ratio of the preview size and the display size, and the preview size is used as the adjusted preview size, so that the image picture can not be greatly stretched or compressed while normally acquiring the image.
In an exemplary embodiment of the present disclosure, when a terminal application invokes a camera, determining, according to an aspect ratio of a display size of the application and an aspect ratio of a preset preview size set by the application, a difference between the aspect ratio of the display size and the aspect ratio of the preset preview size, determining whether the preset preview size needs to be adjusted according to the difference, and when the preset preview size needs to be adjusted, adjusting the preset preview size according to a preview size supported by the camera, acquiring an image according to the adjusted preview size, and displaying the acquired image in the application according to the display size by the application, where a phenomenon that a picture is greatly stretched or compressed does not occur in the image displayed in the application, thereby improving user experience.
