First, an electronic device is provided, as shown in fig. 1, where fig. 1 is a schematic structural diagram of an embodiment of the electronic device. The electronic device 101 of this embodiment at least includes a first camera 102 and a second camera 103, where the first camera 102 is configured to obtain first image data of a shooting object 104, and the second camera 103 is configured to obtain second image data of the shooting object 104.
In this embodiment, the electronic device 101 may further acquire the depth of view image of the captured image according to the first image data and the second image data by using a preset image processing algorithm, but the process of generating the depth of view image is slow, and a user generally needs to wait for several seconds to load and view the captured image from the gallery, so that the user experience is poor.
To solve the above problem, the present application further provides an image display method, as shown in fig. 2, and fig. 2 is a schematic flow chart of a first embodiment of the image display method of the present application. The method of the present embodiment is used for the electronic device 101, and specifically, the method of the present embodiment includes the following steps:
step S201: first image data of the photographic subject 104 is acquired by the first camera 102, and second image data of the photographic subject 104 is acquired by the second camera 103.
The first camera 102 of this embodiment is a main camera of the electronic device 101, and is mainly used for ensuring the imaging quality of a shot image, and the second camera 103 is an auxiliary camera of the electronic device 102, and is mainly used for providing stereoscopic parallax with the main camera so as to calculate depth-of-field information.
The first camera 102 and the second camera 103 are color cameras. Of course, in other embodiments, the first camera and the second camera may also be a black and white camera, a depth camera, a wide-angle lens, a telephoto lens, or the like.
Step S202: a preview image of the photographic subject 104 is acquired from the first image data and displayed on the display screen of the electronic apparatus 101.
Alternatively, as shown in fig. 3, fig. 3 is a specific flowchart of step S202 in the image display method of the embodiment of fig. 2. The method of the embodiment specifically comprises the following steps:
step S301: when the image preview instruction is monitored, a preview image of the photographic subject 104 is acquired according to the first image data.
The preview image of the present embodiment is generated directly from the first image data, the process does not involve fusion processing of a plurality of captured images, the process is relatively simple, and the resolution of the preview image is not high, so that it takes a short time to generate the preview image.
Specifically, the present embodiment may implement step S301 by a method as shown in fig. 4, where the method of the present embodiment includes the following steps:
step S401: pixel information of a plurality of pixel points is obtained from the first image data.
An optical image generated by the photographic subject 104 through the lens of the first camera 102 is transmitted onto the image sensor surface and then converted into an electric signal, which is converted into digital image data after analog-to-digital conversion. The first image data is composed of a plurality of pixel points, and the electronic device 101 may select some or all of the pixel points from the first image data.
Step S402: a preview image of the photographic subject 104 is generated from the pixel information.
The pixel information includes pixel position information, gray information, color information, and the like. In general, the larger the number of acquired pixels is, the slower the speed of generating the preview image is, and the higher the resolution of the preview image is.
Step S302: the preview image is loaded and displayed on the display screen of the electronic device 101.
After the user photographs the photographic object 104 through the first camera 102 and the second camera 103, the user usually needs to open the gallery immediately to check the photographed image, and as can be seen from the above analysis, it takes a long time to obtain the depth of field image of the photographic object 104 according to the first image data and the second image data, in order to meet the requirement of the user to check the photographed image immediately, when an image preview instruction is detected, that is, when the user needs to check the photographed image, the preview image of the photographic object 104 is obtained according to the first image data, and the time required to generate the preview image and load the preview image in the gallery is very short due to the low resolution of the preview image,
specifically, the embodiment may load the image by using the waterfall flow, and may also load the image according to time or shooting location, that is, the image is loaded into the corresponding image file according to time or shooting location, so that the image viewing management is facilitated, and the user experience is improved.
Step S203: the first image data and the second image data are subjected to fusion processing to obtain a depth-of-field image of the photographic subject 104, and the preview image on the display screen is switched to the depth-of-field image.
Alternatively, as shown in fig. 5, fig. 5 is a specific flowchart of step S203 in the image display method of the embodiment of fig. 2. The method of the embodiment specifically comprises the following steps:
step S501: the depth information of the photographic subject 104 is acquired from the first image data and the second image data.
The depth of field is a distance range between the front and rear of the subject measured by imaging in which a clear image can be obtained at the front edge of the camera, that is, a clear image appearing in a range between the front and rear of the focal point after the completion of focusing, and this distance range is called depth of field. The distance between the aperture, the lens and the object is an important factor affecting the depth of field.
Because the first image data and the second image data are obtained by shooting with the first camera 102 and the second camera 103 respectively, and a certain distance exists between the first camera 102 and the second camera 103, so that the parallax caused by the first image data and the second image data can be calculated according to the principle of triangulation distance measurement to obtain the depth information of the same shot object 104 in the first shot image and the second shot image, namely the distance between the shot object 104 and the plane where the first camera 102 and the second camera 103 are located.
Step S502: and acquiring the depth image of the shooting object 104 according to the first image data and the depth information.
Specifically, the scene in the focal plane in the first image data may be retained by a preset algorithm, and then the remaining portion may be subjected to blurring processing or the like according to the depth information.
The smaller the difference between the first image data and the second image data is, the more accurate the depth-of-field image is acquired.
In other embodiments, the steps S501 and S502 may be implemented by the following method:
and blurring the frame image corresponding to the first image data according to a preset blurring rule and the depth information.
Specifically, in order to realize the blurring effect, after the distance between each pixel point in the shot object and the camera is obtained, the definition of the scenery in the focusing plane is kept through a preset algorithm, and the blurring processing is performed on the rest parts according to the distance between the rest parts and the camera, so that the blurring effect can be simulated.
Step S503: and loading the depth image and displaying the depth image on a display screen.
The image loading method in step S503 is the same as that in step S302, and is not described herein.
It should be noted that step S202 and step S203 of the present embodiment are performed simultaneously, that is, the electronic device 101 executes step S202 and step S203 in parallel. As can be seen from the above analysis, the time taken for the electronic device 101 to execute step S202 is significantly shorter than the time taken to execute step S203, and after the depth image of the photographic subject 104 is generated, the electronic device 101 switches the preview image displayed on the display screen to the depth image. Therefore, the user can view the captured image in time after the photographing is finished, and can finally view the depth image of the photographic subject 104.
Different from the prior art, after the camera acquires the image data of the shooting object, the preview image of the shooting object can be rapidly acquired so as to check the image of the shooting object, the preview image does not need to be acquired after the depth image is generated, and the depth image needs to be generated for a long time.
The present application further proposes an image display method of the second embodiment, as shown in fig. 6, the method of the present embodiment includes the steps of:
step S601: the first camera is used for collecting first image data of the shot object, and the second camera is used for collecting second image data of the shot object.
Step S601 is the same as step S201 described above, and is not described herein again.
Step S602: and acquiring first depth-of-field information of the first image data, and matching the first depth-of-field information with first preset depth-of-field information.
The first preset depth of field information is respectively used for judging whether image factors such as the definition of a frame image acquired by the first camera and the like reach a threshold value required for the image quality; the first preset depth of field information can be automatically updated according to the definition information corresponding to the actual shooting object.
Step S603: and if the matching fails, acquiring focusing information of the first camera, and adjusting the focusing information of the first camera to control the first camera to perform focusing adjustment.
The first camera is controlled to perform focusing adjustment so as to obtain a first image meeting the image quality requirement.
Step S604: and acquiring a preview image of the shooting object according to the first image data, and displaying the preview image on a display screen of the electronic equipment.
Step S604 is the same as step S202, and is not described herein.
Step S605: and acquiring second depth-of-field information of the second image data, and matching the second depth-of-field information with second preset depth-of-field information.
The second preset depth of field information is respectively used for judging whether image factors such as the definition of a frame image acquired by the second camera and the like reach a threshold value required for the image quality; the second preset depth of field information can be automatically updated according to the actual definition information corresponding to the shooting object.
Step S606: and if the matching fails, acquiring focusing information of the second camera, and adjusting the focusing information of the second camera to control the second camera to perform focusing adjustment.
And focusing adjustment is carried out by controlling the second camera so as to obtain a second image meeting the image quality requirement.
Step S607: and performing fusion processing on the first image data and the second image data to acquire a depth of field image of the shooting object, and switching the preview image on the display screen into the depth of field image.
Step S607 is the same as step S203 described above, and is not described herein again.
In other embodiments, the execution sequence of steps S606 and S607 and steps S602, S603 and S604 are not limited.
Different from the prior art, the method of the embodiment can improve the definition of the preview image and the depth image on the basis of the method of the embodiment.
In one embodiment, as shown in fig. 7, for a bi-shot photograph, the gallery display picture (image) will be loaded twice:
a primary loading process: firstly, after a user takes a double-shot picture, if the user enters a gallery from a camera to check the picture just taken, the gallery can load the picture for the first time, a preview picture in the original double-shot data is extracted, the preview picture is low in resolution, only a thumbnail overview of the picture just taken is displayed, and the user can see the shot scene in time without waiting. Without this loading, the user needs to wait for a long time in the background to process the blurred picture.
And (3) secondary loading process: meanwhile, in the background double-shot data synchronous processing, after the double-shot algorithm operation is completed, the image library is loaded with secondary images, the rendered depth-of-field images are loaded, the virtual images are displayed, the user feels that the images become clearer, and the depth-of-field effect can be seen. However, the user does not feel a large amount of algorithm operation in the background, waiting is not needed, and smooth experience can be provided for the user.
