Example one
Fig. 3 is a flowchart of a photographing regulating method according to a first embodiment of the present invention. A method for regulating photographing, the method comprising:
s1, acquiring a preview picture of a second image and a first image picture of a first image, wherein the preview picture is generated after the first image picture;
s2, if the correlation between the preview picture and the first image picture exceeds a preset threshold value, executing image processing operation on the first image picture;
s3, synchronously displaying the processed first image picture in the display area of the preview picture;
and S4, showing the difference characteristics of the preview picture and the first image picture through the display area.
In this embodiment, first, a preview screen of a second image and a first image screen of a first image are acquired, wherein the preview screen is generated after the first image screen; then, if the correlation between the preview picture and the first image picture exceeds a preset threshold value, executing image processing operation on the first image picture; then, synchronously displaying the processed first image picture in a display area of the preview picture; finally, the difference characteristics of the preview picture and the first image picture are shown through the display area.
In this embodiment, first, a preview screen of a second image and a first image screen of a first image are acquired, wherein the preview screen is generated after the first image screen. It can be understood that the scheme is applicable to the intelligent terminal device with a shooting function, taking a mobile phone as an example, the first image is acquired through a front camera or a rear camera of the mobile phone, and if the imaging effect of the first image is not satisfactory to a user, when the user returns or restarts a shooting process, the second image is continuously acquired. It is understood that the first image and the second image of the present scheme respectively refer to an imaging taken at the previous time and an imaging taken at the subsequent time in two consecutive photographing processes.
In this embodiment, after a preview screen of a second image and a first image screen of a first image are acquired, if a correlation between the preview screen and the first image screen exceeds a preset threshold, an image processing operation is performed on the first image screen. The image processing operation performed on the first image picture is to perform highlighting processing on a picture obtained by previous shooting, so that a user can compare and contrast the picture in a subsequent second shooting process, for example, highlighting a contour feature of a shot object in an image sharpening manner, or increasing relevant image parameters of a missing effect of the shot object according to an actual effect of the shot object.
In this embodiment, after the image processing operation is performed on the first image picture, the processed first image picture is synchronously displayed in the display area of the preview picture. As described in the foregoing example, after the first image is processed, in order to facilitate the reference for the second shooting operation, the first image is displayed in a manner of being overlaid on the preview image area of the second shooting operation, it is understood that in order to facilitate the display of the first image serving as the reference, it is necessary to avoid that the first image may block the preview image of the second shooting operation, and therefore, the transparency of the first image serving as the reference is processed, so that the user can observe the preview image of the second image and the processed first image at the same time.
In this embodiment, after the processed first image screen is displayed in synchronization with the display area of the preview screen, the difference characteristics between the preview screen and the first image screen are shown in the display area. Similarly, as described in the above example, after the transparency of the first image frame serving as a reference is processed, the user can observe the preview frame of the second image and the processed first image frame at the same time, and by observing the difference characteristics, such as imaging effect, exposure, focusing point, composition mode and other shooting factors, the user can correct the dissatisfied difference characteristics in the second shooting process in real time, thereby preventing the user from repeatedly shooting multiple pictures and then performing post-screening.
The method has the advantages that the preview picture of the second image and the first image picture of the first image are obtained; then, if the correlation between the preview picture and the first image picture exceeds a preset threshold value, executing image processing operation on the first image picture; then, synchronously displaying the processed first image picture in a display area of the preview picture; finally, the difference characteristics of the preview picture and the first image picture are shown through the display area. The humanized photographing regulation and control scheme is realized, the photographing time of the user is reduced, the user can conveniently obtain the required photographing effect, and the time and the energy waste in the photo comparison and screening process are avoided.

In this embodiment, first, a preview screen of a second image and a first image screen of a first image are acquired, wherein the preview screen is generated after the first image screen. It can be understood that the scheme is applicable to the intelligent terminal device with a shooting function, taking a mobile phone as an example, the first image is acquired through a front camera or a rear camera of the mobile phone, and if the imaging effect of the first image is not satisfactory to a user, when the user returns or restarts a shooting process, the second image is continuously acquired. It is understood that the first image and the second image of the present scheme respectively refer to an imaging taken at the previous time and an imaging taken at the subsequent time in two consecutive photographing processes.
Optionally, the scene recognition (or one or more shooting objects) refers to condition detection of whether to perform contrast shooting or not during shooting, when a user finishes shooting a first picture and prepares to shoot a second picture, the system detects information in the camera at the moment, and if the second picture is consistent with the first picture shot scene; a contrast photograph is entered.
Optionally, the scene coincidence refers to comparing data of two photos, and if the similarity of the data of the two photos exceeds 90%, the second photo to be taken is considered to coincide with the scene of the previous photo.
Optionally, the switch for taking a picture by contrast is in the setting item, if the user does not need such a function, the switch can be turned off in the setting, and then the scene recognition and the function of taking a picture by contrast will not be performed later.
Optionally, when the detected scene is consistent and ready to enter the contrast photographing, a message may be popped up to inquire the user whether to enter the contrast photographing mode, and if the detected scene is consistent, the user enters the contrast photographing by clicking a photographing key. If the user wants to cancel, the user presses the 3s photographing key for a long time, the contrast photographing is quitted, the camera is started for the time, the whole process is carried out, the contrast photographing function is closed, and therefore scene detection and user inquiry are not carried out.
Optionally, if the user enters the contrast photographing process, the whole process of starting the camera does not inquire whether to enter contrast photographing, and the whole process starts contrast photographing by default. And comparing the next photo to be shot with the previous photo, if the scenes are consistent, performing contrast photographing by default, and if the scenes are inconsistent, automatically quitting.
The embodiment has the advantages that the relevance judgment operation is controlled through the preset items; then, if the correlation determination operation is started, the correlation determination operation is continuously executed through the preset item in one shooting period. The scheme has the advantages that the more humanized photographing regulation and control scheme is realized, the photographing time of the user is reduced, the user can conveniently obtain the required photographing effect, and the time and energy waste in the photo comparison and screening process is avoided.
