In order to explain the technical solution of the present application, the following description will be given by way of specific examples.
Before android 5.0, manual control of camera shooting parameters can be realized only by changing a system, and an application program interface API (application program interface) Camera1.0 of a camera is not friendly, is similar to a black box with an advanced control function, and is not concerned about shooting parameters of each frame of image shot by the camera. Starting from android 5.0, a new application program interface API Camera2.0 capable of completely controlling the android device camera is introduced, so that the shooting parameters of each frame of image shot by the camera are controlled, and the camera has stronger flexibility.
However, in the shooting process, when performing image preview, the control operation on the shooting parameters of the camera is usually manually performed by the user, for example, sensitivity setting, focal length setting, light metering region selection, aperture size adjustment, shutter speed and saturation, and the like, all need to be manually set by the user one by one, and artificial trial and error is needed to obtain a preview image meeting the conditions, which has the problem of low shooting parameter adjustment efficiency.
In the embodiment of the application, by acquiring a plurality of groups of shooting parameters and sequentially utilizing one group of shooting parameters in the plurality of groups of shooting parameters to update the shooting parameters stored in the preview parameter list at preset time intervals, the shooting parameters stored in the preview parameter list can be automatically updated at preset time intervals, so that a frame image acquisition request generated according to the shooting parameters stored in the preview parameter list can also be automatically updated at preset time intervals, the shooting parameters corresponding to a frame image (preview image) acquired and displayed according to the frame image acquisition request do not need to be manually changed, but are automatically updated at preset time intervals, the adjustment efficiency of the shooting parameters is improved, the gradually-changed image preview effect is achieved, meanwhile, each group of shooting parameters can contain a plurality of shooting parameters, and the simultaneous change of the plurality of shooting parameters is realized, the adjustment efficiency of the shooting parameters is further improved.
Fig. 1 shows a schematic implementation flow diagram of an image preview method provided in an embodiment of the present application, where the method is applied to a terminal, and can be executed by an image preview device configured on the terminal, and is suitable for a situation where it is necessary to improve adjustment efficiency of shooting parameters of a camera, and includes steps 101 to 104.
The terminal comprises terminal equipment which is provided with a shooting preview function, such as a smart phone, a tablet personal computer and a learning machine. The terminal device can be provided with applications such as a photographing application, a browser and a WeChat.
In step 101, a plurality of sets of shooting parameters are obtained.
In the embodiment of the application, the shooting parameters refer to parameters used by the camera during shooting, and each group of shooting parameters may include parameter values such as sensitivity, focal length, light metering area, aperture size, shutter speed and saturation, and are used for the camera to collect external optical signals according to the parameter values. It should be noted that, this is only an example and is not meant to limit the scope of the present application, and in some embodiments of the present application, each set of shooting parameters may include more or less parameters.
The acquiring of the plurality of groups of shooting parameters comprises acquiring a plurality of groups of shooting parameters pre-stored by the terminal; the plurality of groups of shooting parameters pre-stored by the terminal can be shooting parameters collected in the user history shooting process.
For example, after a user takes a satisfactory picture at a certain time in the past, a set of shooting parameters can be obtained by storing the shooting parameters of the picture.
Optionally, in some embodiments of the application, the acquiring multiple sets of shooting parameters further includes: acquiring a plurality of photos selected by a user, and acquiring shooting parameters corresponding to each photo; and generating a plurality of groups of shooting parameters according to the shooting parameters.
The plurality of photos can be photos obtained from the network and selected by the user. For example, the multiple photos may be photos that are obtained from a network according to the geographical location of the current environment of the user and are selected by the user, or photos that are obtained through third-party applications such as WeChat and QQ, so that the multiple sets of shooting parameters are obtained according to the shooting parameters of the photos selected by the user.
In step 102, one of the plurality of sets of shooting parameters is sequentially used to update the shooting parameters stored in the preview parameter list at preset time intervals.
Since the frame images acquired by the camera are acquired according to the frame image acquisition request, that is, each frame image corresponds to one frame image acquisition request, and the frame image acquisition request is generated according to the shooting parameters stored in the preview parameter list, in the embodiment of the present application, after multiple groups of shooting parameters are acquired, each group of shooting parameters in the multiple groups of shooting parameters needs to be sequentially updated according to a preset time interval and covers the shooting parameters in the preview parameter list, so that when the frame image acquisition request is generated according to the shooting parameters stored in the preview parameter list, the frame image acquisition request is the frame image acquisition request corresponding to the multiple groups of shooting parameters.
Moreover, the shooting parameters stored in the preview parameter list are automatically updated at preset time intervals, so that the frame image acquisition request generated according to the shooting parameters stored in the preview parameter list can also be automatically updated at preset time intervals, and finally, the same shooting parameters corresponding to the frame images acquired and displayed according to the frame image acquisition request are automatically updated at preset time intervals, the shooting parameter adjustment efficiency is improved, and the gradual image preview effect is achieved.
It should be noted that, in the image preview process, in order to enable the user to accurately view the frame image corresponding to each group of shooting parameters and to enable the user to have sufficient time to view the frame image corresponding to each group of shooting parameters, the preset time interval needs to be appropriately extended on the basis that the time is longer than the visual retention time of the human eye, and meanwhile, in order to enable the gradual change effect between the frame images corresponding to two adjacent groups of shooting parameters to be in a more ideal state, the preset time interval cannot be set too long. Therefore, in practical applications, the setting of the preset time interval needs to ensure that the user can accurately view the frame image corresponding to each group of shooting parameters and ensure that the gradual change effect between the frame images corresponding to two adjacent groups of shooting parameters is in a relatively ideal state. For example, the preset time interval is set to 3 seconds to 5 seconds, or parameter setting of the preset time interval by a user is received.
In step 103, a frame image acquisition request is generated according to the shooting parameters stored in the preview parameter list, and a frame image corresponding to the frame image acquisition request is acquired and displayed according to the frame image acquisition request.
In this embodiment of the application, when multiple sets of shooting parameters are acquired and one set of shooting parameters in the multiple sets of shooting parameters is sequentially used at preset time intervals to update the shooting parameters stored in the preview parameter list, the terminal needs to generate a frame image acquisition request according to the shooting parameters stored in the preview parameter list, and acquire and display a frame image corresponding to the frame image acquisition request according to the frame image acquisition request, so as to implement image preview.
For example, the terminal generates a frame image acquisition request according to the shooting parameters stored in the preview parameter list, controls the camera to acquire an external optical signal according to the frame image acquisition request to obtain a frame image, and displays the frame image to implement image preview.
In the embodiment of the application, by acquiring a plurality of groups of shooting parameters and sequentially utilizing one group of shooting parameters in the plurality of groups of shooting parameters to update the shooting parameters stored in the preview parameter list at preset time intervals, the shooting parameters stored in the preview parameter list can be automatically updated at preset time intervals, so that a frame image acquisition request generated according to the shooting parameters stored in the preview parameter list can also be automatically updated at preset time intervals, the shooting parameters corresponding to a frame image (preview image) acquired and displayed according to the frame image acquisition request do not need to be manually changed, but are automatically updated at preset time intervals, the adjustment efficiency of the shooting parameters is improved, the gradually-changed image preview effect is achieved, meanwhile, each group of shooting parameters can contain a plurality of shooting parameters, and the simultaneous change of the plurality of shooting parameters is realized, the adjustment efficiency of the shooting parameters is further improved.
In some embodiments of the present application, after acquiring and displaying a frame image corresponding to the frame image acquisition request according to the frame image acquisition request, the method includes: shooting a picture according to a received picture shooting instruction triggered by a user on an image preview interface; or, according to a received video shooting instruction triggered by the user on the image preview interface, video shooting is carried out.
That is, during the image preview process for the fade effect, the user can still normally perform photo shooting or video shooting.
For example, in the process of previewing the image with the gradual change effect, when the user sees a favorite frame image, a photo shooting instruction can be triggered on the image preview interface to shoot the photo, so that the photo with the best shooting effect can be captured in time; or the video shooting instruction is triggered to carry out video shooting so as to shoot the video with the gradual change effect.
It should be noted that the triggering manner of the photo shooting instruction and the video shooting instruction may be triggered by using an existing triggering manner, for example, by clicking a photo shooting selection control or a video shooting selection control in an image preview interface, or by pressing a volume key, which is not described herein again.
Optionally, in some embodiments of the application, as shown in fig. 2, after acquiring and displaying the frame image corresponding to the frame image acquisition request according to the frame image acquisition request, the method may further include: and 104.
In step 104, according to a received frame image selection instruction triggered by the user on the image preview interface, stopping updating the shooting parameters stored in the preview parameter list, generating a frame image acquisition request according to the shooting parameters currently stored in the preview parameter list, and acquiring and displaying a frame image corresponding to the frame image acquisition request according to the frame image acquisition request.
For example, in the process of image preview with a gradient effect, when a user sees a favorite frame image, a frame image selection instruction may be triggered on an image preview interface, so that the terminal stops updating the shooting parameters stored in the preview parameter list, and meanwhile, the terminal can generate a subsequent frame image according to the shooting parameters of the frame image corresponding to the frame image selection instruction.
For another example, as shown in fig. 3, in the process of previewing the image with the gradual change effect, the frame image is converted from the frame image a to the frame image b, at this time, the user triggers a frame image selection instruction corresponding to the frame image b by clicking the preview image in the image preview interface, the terminal stops previewing the image with the gradual change effect, and controls the camera to collect the external optical signal according to the shooting parameter of the frame image b, so as to obtain the frame image with the shooting parameter the same as that of the frame image b.
In some embodiments of the application, after the terminal stops updating the shooting parameters stored in the preview parameter list according to a received frame image selection instruction triggered by a user on an image preview interface, the terminal may shoot a picture according to a received picture shooting instruction triggered by the user on the image preview interface; or, according to a received video shooting instruction triggered by the user on the image preview interface, carrying out video shooting; or, monitoring whether the gradual change preview function is started again, if the gradual change preview function is monitored to be started, initializing the preview parameter list, and sequentially updating the shooting parameters stored in the preview parameter list by using one group of shooting parameters in the multiple groups of shooting parameters according to a preset time interval.
For example, a user can perform normal photo shooting or video shooting after stopping image preview of a gradient effect by clicking a preview image in an image preview interface to trigger a frame image selection instruction corresponding to a frame image b; or, the gradual change preview function of the photographing application is restarted, and image preview of the gradual change effect is carried out.
In the embodiments described in fig. 1 to fig. 3, the image preview of the fade effect may be an image preview of a fade effect performed once when it is monitored that the fade preview function is turned on, that is, each of the multiple sets of shooting parameters is updated only once in the preview parameter list.
For example, before the step 102 sequentially updates the shooting parameters stored in the preview parameter list by using one of the multiple sets of shooting parameters at preset time intervals, the method includes: monitoring whether a gradual change preview function is started; correspondingly, the step of sequentially updating the shooting parameters stored in the preview parameter list by using one group of shooting parameters in the plurality of groups of shooting parameters according to the preset time interval includes: if the starting of the gradual change preview function is monitored, initializing the preview parameter list, and sequentially updating the shooting parameters stored in the preview parameter list by using one group of shooting parameters in the multiple groups of shooting parameters according to a preset time interval.
That is, when it is monitored that the gradual change preview function is started, the shooting parameters currently stored in the preview parameter list are cleared, and the shooting parameters stored in the preview parameter list are sequentially updated by using one of the multiple groups of shooting parameters according to a preset time interval. For example, the image preview of the gradation effect is performed again.
Optionally, the monitoring whether the preview function is turned on further includes: and if the gradual change preview function is not started, generating a frame image acquisition request according to preset shooting parameters, and acquiring and displaying a frame image corresponding to the frame image acquisition request according to the frame image acquisition request. The preset shooting parameters refer to the default shooting parameters of the shooting application.
In some embodiments of the present application, as shown in fig. 4, the execution of step 102 may further include steps 401 to 403.
In step 401, sequentially using one of the multiple sets of shooting parameters to update the shooting parameters stored in the preview parameter list according to a preset time interval;
in step 402, it is determined whether the last group of shooting parameters in the plurality of groups of shooting parameters is used to update the shooting parameters stored in the preview parameter list;
in step 403, after determining that the shooting parameters stored in the preview parameter list are updated by using the last shooting parameter of the multiple sets of shooting parameters, the shooting parameters stored in the preview parameter list are updated by sequentially using one set of shooting parameters of the multiple sets of shooting parameters again according to a preset time interval.
That is to say, the image preview of the gradual change effect may be an image preview of a gradual change effect executed in a cycle when it is monitored that the gradual change preview function is started, that is, each group of shooting parameters in the multiple groups of shooting parameters may be updated into the preview parameter list in each cycle period, so as to achieve the effect of the cyclic gradual change preview, and it is not necessary to start the gradual change preview function again after the image preview of the gradual change effect is completed, so as to perform the image preview of the next gradual change effect, but to directly perform the image preview of the next gradual change effect, thereby further improving the adjustment efficiency of the frame image shooting parameters in the image preview process.
It should be noted that, for simplicity of description, the foregoing method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present application is not limited by the order of acts described, and that some steps may occur in other orders or concurrently in the embodiments herein. For example, the step 103 is a step continuously executed after the camera application is turned on, that is, the step 103 is performed simultaneously with the steps 101 and 102.
