Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart of a photographing method according to an embodiment of the present disclosure, and as shown in fig. 1, the photographing method applied to a terminal includes the following steps:
s11, based on a detected photographing instruction, acquiring and generating a first image queue and a second image queue with the same image content; the data size of the single-frame images in the second image queue is smaller than that of the single-frame images in the first image queue;
s12, determining a target image from the first image queue, and performing image quality optimization processing on the target image;
s13, determining an image with the same generation time as the generation time of the target image in the second image queue as a thumbnail of the target image;
s14, when an operation instruction acting on the thumbnail is detected, outputting a target image after image quality optimization processing.
In an embodiment of the present disclosure, a terminal includes: smart phones, cameras, tablet computers, or wearable electronic devices, etc. The mobile terminal is provided with an image acquisition component, and shooting is realized through the image acquisition component. Taking a mobile phone as an example, the image acquisition assembly comprises a front camera and a rear camera in the mobile phone.
In step S11, the terminal collects and generates a first image queue and a second image queue having the same image content based on the detected photographing instruction. The photographing instruction may be a touch instruction detected by the terminal, or a voice instruction detected by the terminal. In addition, the data amount of the single-frame image in the second image queue is smaller than the data amount of the single-frame image in the first image queue, for example, the number of pixels of the single-frame image in the second image queue is smaller than the number of pixels of the single-frame image in the first image queue, or the image resolution of the single-frame image in the second image queue is smaller than the image resolution of the single-frame image in the first image queue.
In an embodiment of the disclosure, the single frame image in the first image queue may be an image stored in the terminal for display to a user or for information interaction with other applications, and the single frame image in the second image queue may be a preview image on a display interface of the terminal. The terminal may also synchronously save the generation time of each image when generating the first image queue and the second image queue having the same image content.
In step S12, the terminal determines a target image from the first image queue, and performs image quality optimization processing on the target image.
In one embodiment, the image quality optimization processing for the target image includes:
denoising the target image; and/or the number of the groups of groups,
performing distortion correction processing on the target image; and/or the number of the groups of groups,
and performing color correction processing on the target image.
In the embodiment of the present disclosure, the image quality optimization processing for the target image includes denoising processing, for example, denoising processing for the image may be performed using a method such as an average filter or wavelet transform. The image quality optimization processing for the target image may also include distortion correction processing such as distortion correction based on perspective transformation, or the like. In addition, the image quality optimization processing for the target image may also include color correction processing, such as processing for removing purple fringing. However, the image quality optimization processing performed on the target image by the present disclosure is not limited to the above, and may include, for example, contrast adjustment and the like.
In some embodiments, the image quality optimization processing of the target image may further include, but is not limited to, at least one of:
image shake eliminating processing;
image contrast enhancement processing.
In step S13, the terminal determines, as a thumbnail of the target image, an image having the same generation time as the generation time of the target image from the second image queue, to output the target image after the image quality optimization processing when an operation instruction acting on the thumbnail is detected in step S14.
As described above, when the terminal generates the first image queue and the second image queue, the generation time of each image is synchronously saved, so that after the target image is determined from the first image queue, the thumbnail of the target image can be determined from the second image queue based on the generation time. When the terminal detects an operation instruction for the thumbnail, the terminal can output the target image after the image quality optimization processing.
In an application supporting photographing, for example, after a photographing instruction detected by a terminal generates a first image queue and a second image queue, a target image and a thumbnail may be determined, so that a user may determine whether the target image after the image quality optimization process in the cache is sent to the other party through the thumbnail.
In one embodiment, the method further comprises:
the target image is stored into an album after being subjected to image quality optimization treatment;
and outputting the target image after the image quality optimization processing if the operation instruction acting on the thumbnail is detected, wherein the method comprises the following steps:
and if the operation instruction acting on the thumbnail is detected, reading the target image subjected to the image quality optimization processing from the album and outputting the target image.
In the embodiment of the disclosure, the target image after the image quality optimization processing can be saved to an album application, namely, saved locally at the terminal, so that the user can conveniently view the target image at any time. When the image is obtained based on the photographing instruction, the user can conveniently check the image through the thumbnail associated album application, so that after the operation instruction acting on the thumbnail is detected, the target image after the image quality optimization processing is read from the album and output.
In the embodiment of the present disclosure, since the thumbnail and the target image are generated by being acquired at the same time, the image content of the thumbnail and the image content of the target image are identical. In the present disclosure, the image quality of the target image is changed without changing the content of the image, so that the content of the thumbnail image is the same as the content of the target image after the image quality is optimized.
Based on the same image content, when the terminal detects an operation instruction for the thumbnail to output the target image after the image quality optimization processing, for example, when the terminal displays the target image after the image quality optimization processing, the jump when switching from the thumbnail to the target image after the image quality optimization processing can be reduced, and thus the user experience can be improved.
In addition, the thumbnail is from the second image queue, the images in the second image queue are generated together with the images in the first image queue after the photographing instruction is detected, no additional algorithm processing is needed to be executed to obtain the thumbnail, and no jump exists, blurring and other processing is not needed to be carried out on the thumbnail, so that time consumption can be reduced, and user experience is improved.
In one embodiment, the determining the target image from the first image queue includes:
if the first image queue comprises a single frame image, determining the single frame image as the target image;
and if the first image queue comprises a plurality of images, selecting an image meeting a preset condition from the plurality of images as the target image.
In the embodiment of the disclosure, when the terminal generates the first image queue based on the photographing instruction acquisition, a single-frame image can be generated and a multi-frame image can be generated. If the generated first image queue comprises a single frame image based on the current photographing instruction, determining the single frame image as a target image; if the first image queue generated based on the current photographing instruction comprises a plurality of images, selecting an image meeting a preset condition from the plurality of images as a target image.
It can be understood that, based on the current photographing instruction, a first image queue including one frame of image is generated, so that a target image is determined, and the processing speed of the scheme of the present disclosure can be improved; based on the current photographing instruction, a first image queue comprising a plurality of frames of images is generated, and an image meeting a preset condition is selected from the first image queue as a target image, for example, the generated first frame of image may not have complete image content or poor image quality, or some frames of images may have poor image quality, etc., so that the method and the device can improve the acquisition quality of the target image, thereby improving the user experience.
In one embodiment, selecting an image satisfying a preset condition from the multi-frame images as the target image includes:
selecting an image satisfying a predetermined number from the multi-frame images as the target image; or,
and selecting an image meeting preset image quality from the multi-frame images as the target image.
In this embodiment, the image satisfying the predetermined number is, for example, an intermediate frame image determined in accordance with the camera performance as the target image, the image content of which is complete and the image quality is superior. And the image satisfying the preset image quality is, for example, an image of normal exposure or the like.
Because the target image is an image to be output after the image quality optimization processing, for example, the image is displayed to a user for viewing, the method and the device determine the target image in the first image queue comprising the multi-frame images in the two modes, and can improve the image quality of the obtained target image, thereby improving the photographing experience of the user.
In one embodiment, selecting an image satisfying a preset image quality from the multi-frame images as a target image includes:
and sorting the image quality of the multi-frame images, and selecting the image with the best quality or higher than a quality threshold as a target image.
For example, the terminal stores an image quality score of each frame image, and an image with the best quality or higher than a quality threshold can be selected as a target image according to the image quality score.
In one embodiment, the image quality optimization processing for the target image includes:
and after determining the thumbnail of the target image, performing image quality optimization processing on the target image.
In the embodiment of the disclosure, after the thumbnail of the target image is determined, the target image is subjected to image quality optimization processing, so that after the terminal detects a photographing instruction, the terminal can feed back a thumbnail to a user first, and user experience is improved. Meanwhile, in the gap of displaying the thumbnail or in the gap of detecting the operation instruction acting on the thumbnail to the target image after switching to the image quality optimization processing, the background can synchronously perform the image quality optimization processing on the target image, so that the time from the detection of the photographing instruction to the acquisition of the target image after the image quality optimization processing can be shortened as a whole, and the user experience can be improved.
After detecting the operation instruction for the thumbnail, the present disclosure may read the target image after the image quality optimization process from the album and output the target image as described above. However, since the thumbnail of the present disclosure is generated soon, the target image may be still subjected to the image quality optimization processing upon detection of the operation instruction. In this case, based on detection of an operation instruction for the thumbnail, the thumbnail may be temporarily displayed on the display screen based on the size of the display screen, for example, the image content of the thumbnail is displayed full screen. And when the background completes the optimization processing of the target image, storing the target image into the album, and replacing the thumbnail on the display screen with the target image after the optimization processing in the album. It can be understood that by the method, before the target image with optimized image quality is not generated, photographing content can be displayed immediately based on the detected operation instruction, so that the use experience of a user can be improved.
In one embodiment, the method further comprises:
and after the thumbnail of the target image is determined, outputting prompt information of the photographing state.
In the embodiment of the disclosure, after determining the thumbnail of the target image, the terminal outputs prompt information of the photographing state. In one embodiment, the prompt information of the photographing state includes at least one of the following:
photographing sound;
and shooting the animation.
The photographing sound may be a sound perceived by the user and representing that the terminal performs photographing, such as "clicking" for example, and the photographing animation is a picture that the user can observe that the display page of the display screen of the terminal flickers. It can be understood that, because the time consumption for determining the thumbnail is shorter, prompt information of the photographing state is output after the thumbnail is determined, so that a user can quickly know that the terminal is executing a photographing instruction, and the use experience of the user can be improved.
In embodiments of the present disclosure, after determining the thumbnail, the thumbnail may be displayed on a display screen for user operation. It should be noted that the thumbnail may be displayed after the photo movie is displayed. Further, the display position of the photographing animation and the display position of the thumbnail may be different, for example, the photographing animation is displayed in a center area of a display screen of the terminal, and the thumbnail may be displayed in a corner of the display screen.
Fig. 2 is an exemplary illustration of a photographing method, as shown in fig. 2, the photographing method applied to a terminal includes the following steps:
s101, detecting shooting instructions of a user.
In an embodiment of the present disclosure, a processor of the terminal may detect a photographing instruction of a user.
S102, issuing shooting instructions to the bottom camera.
After the processor of the terminal detects the shooting instruction of the user, the shooting instruction is sent to the camera application, so that the camera application executes shooting.
S103, the bottom camera executes a photographing process to generate an original photo.
The photographing process includes Auto Focus (AF), auto exposure (Automatic Exposure, AE), and Auto white balance (Automatic white balance, AWB), also referred to as a 3A process. In this embodiment, the original photo is for subsequent saving to the album application.
S104, the original photo is processed by algorithms such as multi-frame noise reduction, distortion correction and the like.
S105, returning the processed photos to the camera application.
S106, the camera application plays photographing sound and executes photographing animation.
S107, the camera application saves the large graph, then generates a thumbnail according to the large graph, and updates the thumbnail.
The large image is the image processed by the algorithm.
S108, detecting an operation instruction for the thumbnail, and jumping to the album display large image.
From the above steps, the original photo is processed and then is stored as a thumbnail, and all operations are serial, so that the time consumption is long; and the user must wait until the camera application receives the large image and then check the large image by clicking the thumbnail after the large image is stored, so that the user experience is poor.
Fig. 3 is an exemplary illustration of a photographing method, as shown in fig. 3, the photographing method applied to the terminal includes the following steps:
s201, detecting a shooting instruction of a user.
In an embodiment of the present disclosure, a processor of the terminal may detect a photographing instruction of a user.
S202A, intercepting a preview frame.
S202B, issuing shooting instructions to the bottom camera.
After the processor of the terminal detects the shooting instruction of the user, the shooting instruction is sent to the camera application, so that the camera application executes shooting.
S203A, receiving and saving the preview frame, and simultaneously playing the photographing sound and the animation.
S203B, the bottom camera executes a photographing process to generate an original photo.
In this embodiment, the original photo is for subsequent saving to the album application.
S204A, generating a thumbnail according to the stored preview frame and updating.
S204B, carrying out algorithm processing on the original photo.
For example, the original photograph is subjected to denoising, distortion correction and the like.
S205A, detecting an operation instruction for the thumbnail, and jumping to the album.
S205B, returning the large graph to the camera application.
The large image is the image processed by the algorithm.
S206A, displaying an image.
It should be noted that the image seen by the user at this time is not a true large image, but a preview frame.
S206B, the camera application saves the large image and notifies the album.
S207A, the album blurs the preview frame to prompt the user that the large image is being generated.
S207B, displaying a large picture by the album, and removing blurring.
As can be seen from the above steps, since the preview frame is displayed on the display screen of the current image frame and the large image is based on the image processed by the algorithm, there may be inconsistency between the current preview frame and the large image, and thus, a frame jump may occur. Especially when shooting a moving object, the currently displayed image frame can change immediately due to the motion of the object, so that jump can be more serious, and the user experience is affected. In addition, because the thumbnail obtained based on the preview frame and the large image stored in the album are processed in two ways, when the user clicks the thumbnail, the large image may not be generated and completed, and the fuzzy processing of the thumbnail by the scheme also affects the user experience in consideration of the jump of the content.
To overcome the shortcomings in the second and third diagrams, the present disclosure provides a new photographing method, and fig. 4 is an exemplary diagram of a photographing method of the present disclosure, as shown in fig. 4, the photographing method includes the following steps:
s301, detecting a shooting instruction of a user.
In an embodiment of the present disclosure, a processor of the terminal may detect a photographing instruction of a user.
S302, shooting instructions are issued to the bottom camera, and two paths of streams are issued.
After the processor of the terminal detects the shooting instruction of the user, the shooting instruction is sent to the camera application, so that the camera application executes shooting. The disclosed processor also issues two-way streams to inform the camera that two-way images need to be generated. One path is a normal large-image data stream, for example, the size of a single-frame image is 12 megabits (M) or 48M, and the data stream is a data stream corresponding to a first image queue for storing a large number of images; the other path is the data flow of the thumbnail, the data volume is smaller, and the data flow is generally equal to the data volume of the preview frame, and the data flow is the data flow corresponding to the second image queue for storing the images with small quantity.
S303, the camera executes a photographing flow to generate an original photo.
In an embodiment of the present disclosure, generating the original photograph includes generating a first image queue and a second image queue having the same image content.
S304, before the algorithm is performed, the key frame is reported.
In this embodiment, the key frame is the target image of the present disclosure. If the first image queue comprises a single-frame image, determining the single-frame image as a key frame; if the first image queue comprises a plurality of images, selecting images meeting preset conditions from the plurality of images as key frames.
S305A, taking frames of thumbnail images from small data stream, playing shooting sound and animation.
In this embodiment, a frame from a small data stream to a thumbnail, specifically, an image having the same generation time as that of a key frame is selected from the second image queue, and the image is determined as a thumbnail.
After the frame of the thumbnail is determined, shooting sound and animation can be played, and the user terminal is prompted to be in a shooting state.
S305B, returning the large graph processed by the algorithm to the camera application.
In this embodiment, the large image processed by the algorithm is the target image processed by the image quality optimization, and the target image is saved to the camera application.
S306A, storing the thumbnail and updating.
