Abstract
The invention discloses a display method of photos with various focal lengths, which is used for acquiring a group of photos which are provided by a user and are shot by switching different focal lengths by using a photographic device to shoot an original scene. And analyzing and sorting the focal lengths recorded in the photos, and taking the photos with the focal lengths being median for default display. When the user performs the photo zoom-out operation, the user switches to the photo with the smaller focal length for displaying and operating, and when the user performs the photo zoom-in operation, the user switches to the photo with the larger focal length for displaying and operating. The display photos are switched by utilizing the focal length attributes of the photos, so that the scenes with different distances in the original shot scenes are better displayed, the details and the definition of the scenes with different distances in the original shot scenes are better presented, and the problems of distortion and blurring of the scenes with partial distances in the original shot scenes presented by a traditional photo viewer are solved.
Description
Technical Field
The invention relates to the technical field of image processing and display, in particular to a display method of photos with various focal lengths.
Background
The current photo viewer in the market uses the same enlarged and reduced photo when viewing the photo, because the focal length when taking the photo is fixed, the photo can only partially and perfectly present the details of the scenery in the shooting distance section, and the scenery in other distance sections is always blurred and distorted. Causing the user to use the photo viewer to zoom in and out on the partial image of the photo with less than satisfactory results.
Disclosure of Invention
The invention aims to provide a display method of photos with various focal lengths.
The technical scheme adopted by the invention is as follows:
a method of displaying photographs having a plurality of focal lengths, comprising the steps of:
step 1, acquiring a group of photos shot by a user and shot by the same shooting original scene at different focal lengths;
step 2, analyzing and sorting the group of photos according to the recorded focal length;
step 3, selecting the photos with the focal length of the median in the group of photos as default display photos;
and 4, when the user performs the zooming-in or zooming-out operation, switching to the photo with the proper focal length for displaying and operating.
Further, the group of photos in step 2 are arranged in order from large to small according to the focal length.
Further, in step 3, when the number n of the group of photos is odd, the (n + 1)/2 photos are selected as the focal length median photos.
Further, in step 3, when the number n of the group of photos is even, the (n/2) th photo is selected as the focal length median photo.
Further, in step 3, when the number n of the group of photos is even, the (n + 2)/2 th photo is selected as the focal length median photo.
Further, in step 4, when the user performs the photo zoom-out operation, the user switches to the photo with the smaller focal length for displaying and operating; when the user zooms in the photos, the photos with larger focal length are switched to be displayed and operated.
Further, in step 4, the zooming operation is divided into a plurality of zooming sections according to the number of the photos between the median focal length and the maximum focal length, and each zooming section corresponds to one focal length of the photo.
Further, in step 4, the zoom-out operation is correspondingly divided into a plurality of zoom-out sections according to the number of the photos between the median focal length and the minimum focal length, and each zoom-out section corresponds to one focal length of the photos.
By adopting the technical scheme, the invention obtains a group of pictures which are provided by a user and are shot by switching different focal lengths by using the photographic equipment for the same original scene. And analyzing and sorting the focal lengths recorded in the photos, and taking the photos with the focal lengths being median for default display. When the user performs the photo zooming-out operation, the user switches to the photo with the smaller focal length for displaying and operating, and when the user performs the photo zooming-in operation, the user switches to the photo with the larger focal length for displaying and operating. The display photos are switched by utilizing the focal length attributes of the photos, so that the scenes with different distances in the original shot scenes are better displayed, the details and the definition of the scenes with different distances in the original shot scenes are better presented, and the problems of distortion and blurring of the scenes with partial distances in the original shot scenes presented by a traditional photo viewer are solved.
Drawings
The invention is described in further detail below with reference to the accompanying drawings and the detailed description;
FIG. 1 is a flow chart illustrating a method for displaying a plurality of photographs with different focal lengths according to the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
As shown in fig. 1, the invention discloses a method for displaying photos with various focal lengths, which comprises the following steps:
step 1, acquiring a group of photos shot by a user and shot by the same shooting original scene at different focal lengths;
step 2, analyzing and sorting the group of photos according to the recorded focal length;
step 3, selecting the photos with the focal length of the median in the group of photos as default display photos;
and 4, when the user performs the zooming-in or zooming-out operation, switching to the photo with the proper focal length for displaying and operating.
Further, the group of photos in step 2 are arranged in order from large to small according to the focal length.
Further, in step 3, when the number n of the group of photos is odd, the (n + 1)/2 photos are selected as the focal length median photos.
Further, in step 3, when the number n of the group of photos is even, the (n/2) th photo is selected as the focal length median photo.
Further, in step 3, when the number n of the group of photos is even, the (n + 2)/2 th photo is selected as the focal length median photo.
Further, in step 4, when the user performs the photo zoom-out operation, the user switches to the photo with the smaller focal length for displaying and operating; when the user zooms in the photos, the photos with larger focal length are switched to be displayed and operated.
Further, in step 4, the zooming operation is divided into a plurality of zooming sections according to the number of the photos between the median focal length and the maximum focal length, and each zooming section corresponds to one focal length of the photo.
Further, in step 4, the zoom-out operation is correspondingly divided into a plurality of zoom-out sections according to the number of the photos between the median focal length and the minimum focal length, and each zoom-out section corresponds to one focal length of the photos.
By adopting the technical scheme, the invention obtains a group of pictures which are provided by a user and are shot by switching different focal lengths by using the photographic equipment for the same original scene. And analyzing and sorting the focal lengths recorded in the photos, and taking the photos with the focal lengths being median for default display.
