In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
The technical solution of the present invention is described in detail below with specific embodiments, where the terminal device in the following embodiments of the present invention is an intelligent terminal with a camera, such as a smart phone, a self-timer camera, a tablet computer, or a Personal Digital Assistant (PDA), and the terminal device in the following embodiments of the present invention generally further has a display screen capable of displaying real-time taken images or displaying photos. The following specific embodiments of the present invention may be combined, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a flowchart of a photographing processing method according to an embodiment of the present invention. The photographing processing method provided by the embodiment is suitable for the condition of photographing through a front camera of the terminal device, the method can be executed by the photographing processing device, the photographing processing device is realized in a mode of combining hardware and software, and the photographing processing device can be integrated in a processor of the terminal device and used for being called by the processor. As shown in fig. 1, the method provided by this embodiment may include:
and S110, acquiring image data through a front camera of the terminal equipment.
The terminal equipment used at present generally has a photographing function and also has the capability of performing post-processing on a photographed image, such as beauty processing, picture mirror processing and the like. The photographing processing method provided by each embodiment of the invention is mainly applied to the image processing process after photographing through the front-facing camera, and no matter which photographing mode is adopted, firstly, the camera is required to obtain the image data in the photographing field range, and further processing is executed on the basis of the obtained image data. The specific application scenario may be, for example: the self-shooting is carried out through a front camera of the smart phone.
It should be noted that the embodiments of the present invention may be applied to a photographing scene equivalent to a front-facing camera, for example, a camera in a smart phone is a rotary camera, and when the camera is rotated to the same side as a display screen, the camera is used as the front-facing camera, for example, a display screen of some micro single cameras may be rotated by 180 degrees, and a photographing effect after rotating the display screen is equivalent to a photographing effect of the front-facing camera. In the following embodiments of the present invention, the front-facing camera and the camera having the same photographing effect as the front-facing camera are collectively referred to as the front-facing camera, and will not be described in detail below.
And S120, detecting the characteristic information of the image data to obtain a detection result.
In the embodiment, the image data in the shooting field of view has been acquired by the front camera, and shooting with the front camera is usually self-portrait, i.e. the image data may have human face, scenery or other contents in the image data. In this embodiment, the detection result is a basis for processing image data acquired by the front-facing camera, and the feature information is a key parameter for performing detection.
In an application scenario of performing detection, the feature information may be an object to detect image data, in which case, the feature information is a specific detection result, for example, the feature information includes one or more items of face information and text information; in another application scenario of performing detection, the feature information may be a detection target value preset in the terminal device, that is, a comparison parameter for performing detection, for example, the detected target value is face information, and it is detected whether the image data has content related to the face information during detection, where the detection result is usually the presence or absence of data content related to the feature information. In the different application scenarios, the detection execution principles and modes are different, and the obtained detection results are also different; however, the detection is performed for the purpose of determining the manner in which the image data acquired by the front camera is processed.
It should be noted that the present invention is not limited to the above-mentioned several specific ways of performing detection, and as long as the key data for determining the image processing way can be obtained by detecting the image data, the detection behavior of the present invention can be taken; for example, a specified region in the image data is detected.
And S130, carrying out mirror image processing or neglecting mirror image processing on the image data according to the detection result.
In the present embodiment, the detection result of the image data has been acquired, and the detection result may be in different forms and contents, whichever form of the detection result has a key factor in determining how to process the image data. For example, in this embodiment, the mode of performing photographing is usually self-photographing, a face is in a photographing field, in this case, the detection result is, for example, face information or face information in image data, and at this time, in order to meet the requirement of what a user sees in self-photographing is what he obtains, the terminal device may perform mirror image processing on the image data; for another example, when the user performs self-shooting through the front camera, the shooting field of view has text content, or the text content occupies a large proportion of the shooting field of view, such as a background billboard or a text on a person's clothing, at this time, if the image data is subjected to mirror image processing, the text in the generated picture is in a state of opposite left and right, like the text on a printing plate, and the reality of the picture is poor, in this case, the mirror image processing can be omitted for the image data, that is, the shot picture can output a correct text effect, and the text content conforming to the reading habit is obtained. In the embodiment, the detection result is used as the trigger condition for turning on or off the mirror image processing function, so that the self-adaptive switch of the mirror image function in the self-photographing image processing process can be realized, the subjectivity of manual judgment is avoided, and the complex operation process is also avoided.
In the conventional manner of performing self-photographing through a front camera, a common implementation manner is as described in the above background art, a function switch is set for a camera of a terminal device, and a mirror image processing function is turned on or turned off through setting by a user, which requires the user to subjectively judge a processing manner suitable for current photographing and perform manual setting operation by the user, the operation of manually setting the function switch is complicated, the position of the function switch needs to be found, and setting positions of the function switch by different self-photographing application programs may be different; in addition, the setting of function switch may need to be changed according to judgment in the photographing process, a complex experience effect of photographing setting is brought to a user, and the photographing efficiency and the intelligence are poor.
The photographing processing method provided by this embodiment obtains image data through a front-facing camera of a terminal device, detects characteristic information of the image data to obtain a detection result, and performs mirror image processing or ignores the mirror image processing on the image data obtained by the front-facing camera through the detection result, and this embodiment uses the detection result of the image data as a trigger condition for turning on or turning off a mirror image processing function, thereby implementing an adaptive switch for the mirror image function in the image processing of the front-facing camera, and simultaneously avoiding a user from executing a complicated setting operation, and solving the problem that in the prior art, in a processing mode of photographing by using the front-facing camera, the mirror image processing function is turned on or turned off through the setting of the user, since the user needs to subjectively judge a processing mode suitable for the current photographing and performs a manual setting operation by the user, thereby leading the photographing operation steps to be complicated, and the problem of picture distortion easily occurs.
Further, in the shooting process of the front-facing camera in the prior art, the user is required to judge the processing mode suitable for the current shooting by himself, the user judgment has certain subjectivity, and the judgment is easy to cause misunderstanding for the user, especially for the user who does not know the mirror image function, if the mirror image function is turned on by default in the terminal device, the problem of shooting distortion can occur when characters are shot, and if the mirror image function is turned off by default, the user may not be satisfied with the self-shooting effect, resulting in the complaint of the user.
Optionally, the feature information in the embodiment shown in fig. 1 is a detection result, and on the basis of the embodiment shown in fig. 1, S120 in this embodiment may be replaced with: detecting the characteristic information in the image data, and obtaining a detection result comprising the characteristic information, wherein the characteristic information comprises one or more items of face information and character information.
In this embodiment, the detected feature information, that is, the detection result, may be different information or a combination of different information, for example, if the detected feature information is face information, the image data is processed in a mirror image manner; for another example, if the detected feature information is character information, the image data is processed by omitting the mirror image processing. Obviously, the principle that the mirror processing function is started when the face is photographed and the mirror processing function is stopped when the characters are photographed is followed in the embodiment, that is, the authenticity of the photographed picture is ensured as much as possible in different application scenes.
In a more complex case of the present embodiment, the detected feature information includes a combination of face information and text information, and the analysis processing can be performed according to the feature information. As shown in fig. 2, which is a flowchart of another photographing processing method according to an embodiment of the present invention, in this embodiment, a reference region is set in image data acquired by a front-facing camera, the face information includes a position and a size of a face region, and the text information includes a position and a size of a text region. As shown in fig. 3, which is a schematic diagram of image data obtained by the photographing processing method provided in the embodiment shown in fig. 2, a field of view region and a reference region of the front camera are identified in the diagram, the reference region is generally located at a center position of the field of view region, and a size and a position of the reference region may be changed by a user setting, in a specific implementation of this embodiment, S130 may include:
s131, determining the position relation and the proportional relation between the face area and the character area and the reference area according to the position and the size of the face area and the position and the size of the character area.
And S132, when the ratio of the face area occupying the reference area is greater than a first threshold value, carrying out mirror image processing on the image data.
And S133, when the ratio of the character area occupying the reference area is greater than a second threshold value, ignoring mirror image processing on the image data.
In this embodiment, the position and size of the face region, the position and size of the text region, and the reference region may be in the format of image information, and the position and size of the different regions may also be in the format of data information, such as coordinates of image boundary points; the terminal equipment determines which information in the image is more important based on the ratio of the face area or the character area occupying the reference area, and the information is used as a basis for determining the processing mode. For example, when a user takes a self-timer, a human face usually occupies a large range of a reference area, and at this time, mirroring can be performed; for another example, when a user holding a reward certificate takes a self-timer, the content of the certificate is expected to be embodied, at this time, a larger range of the reference area is occupied by characters in the certificate, and the mirroring process can be omitted to ensure the correctness of the characters of the certificate.
It should be noted that the first threshold and the second threshold in this embodiment may be set to be the same data or different data, but generally cannot be set to be data that may have conflicts in the application, for example, setting the first threshold to be 40% and the second threshold to be 35%, there may be conflicts, and setting the first threshold to be 50% and the second threshold to be 60%, there may be no conflicts; in addition, S132 and S133 in this embodiment are alternatively executed.
It should be further noted that the embodiment shown in fig. 2 is a possible implementation manner of the present invention, and the present invention does not limit the specific manner of turning on or off the mirror image processing function under the condition that the feature information includes a combination of face information and text information, for example, a proportional relationship between a face region and a text region in the entire field of view may be determined, and for example, the focus range may be used as a reference region.
Optionally, the feature information in the embodiment shown in fig. 1 may also be a detection target value preset in the terminal device, where the feature information is, for example, face information or text information, and on the basis of the embodiment shown in fig. 1, S120 in this embodiment may be replaced with: and detecting the image data and judging whether the image data has data content meeting the characteristic information.
