Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

The photographing processing method described below may be implemented by a mobile terminal, that is, the mobile terminal may perform the respective steps of the photographing processing method of the exemplary embodiment of the present disclosure, in which case the photographing processing apparatus described below may be disposed in the mobile terminal.

The mobile terminal disclosed by the disclosure includes but is not limited to a mobile phone, a tablet computer, a smart wearable device and the like.

Fig. 1 schematically shows a flowchart of a photographing processing method of an exemplary embodiment of the present disclosure. Referring to fig. 1, the photographing processing method may include the steps of:

and S12, acquiring preview image data of a camera of the mobile terminal in a first output mode, and detecting the distance between a target object and the mobile terminal in the current shooting scene according to the preview image data.

After the camera is turned on and before shooting is performed, the camera may be usually in a preview state in which the camera may output preview image data.

The present disclosure does not limit the kind of the camera on the mobile terminal as long as the camera can have different output mode functions. The output mode described in the present disclosure may be understood as a mode in which captured image data is output in a certain pixel. It should be understood that in the description of the present disclosure, the pixels corresponding to different output modes are different, and the output resolution of different output modes can be considered to be different.

When the camera performs preview, an output mode with relatively low pixels is often adopted, and this output mode is referred to as a first output mode by the present disclosure. Correspondingly, the output mode of the relatively high pixels is denoted as the second output mode.

Taking a camera with 6400 ten thousand pixels as an example, the output mode may include an output with 1600 thousand pixels and an output with 6400 thousand pixels. Normally, if a camera of 6400 ten thousand pixels is in a preview state, 1600 ten thousand pixels are output. In the case of a camera having 6400 ten thousand pixels, the first output mode according to the present disclosure may be a mode in which image data is output at 1600 ten thousand pixels, and the second output mode may be a mode in which image data is output at 6400 ten thousand pixels.

The mobile terminal may detect a distance of a target object from the mobile terminal in a current shooting scene using the preview image data.

For the process of determining the target object, according to some embodiments of the present disclosure, the mobile terminal may identify each object in the current shooting scene by using the preview image, and determine a type corresponding to each object. Specifically, the type corresponding to each object may be determined by using methods such as edge detection and neural network, for example, the type may include buildings, people, cars, flowers and plants, and the like. Next, an object occupying the largest proportion of the area of the preview image may be determined as a target object from among objects whose types belong to a preset type. For example, the preview image includes 5 objects, which are respectively denoted as object a, object B, object C, object D, and object E, and if the preset type is human, in this case, object a and object D are human, and the area occupation ratio of object a in the preview image is 25%, and the area occupation ratio of object D in the preview image is 30%, then object D is the target object. It should be understood that the preset type may be set by the user, and the present disclosure is not limited thereto.

For the process of determining the target object, according to other embodiments of the present disclosure, a preview image may be displayed on an interface of the mobile terminal. In this case, in response to a selection operation of the user for a region in the preview image, an object corresponding to the selected region may be determined as the target object. For example, if the preview image includes a cat, and the user clicks an area corresponding to the cat on the interface of the mobile terminal, the cat may be used as the target object.

It should be understood that the target object is an object that the user focuses on or is interested in the current shooting scene.

After the target object is determined, the distance from the target object to the mobile terminal can be detected by using the preview image data. Specifically, the distance detection may be implemented by using, for example, a similar triangle method, however, the present disclosure does not limit the specific process of detecting the distance, and may also implement the distance detection between the target object and the mobile terminal by using other monocular distance measurement methods.

S14, if the distance between the target object and the mobile terminal is larger than a distance threshold value, switching the output mode of the camera to a second output mode, and outputting the shot image by using the second output mode; wherein the pixels of the first output mode are lower than the pixels of the second output mode.

In an exemplary embodiment of the present disclosure, the pixels of the first output mode are lower than those of the second output mode, and still take a camera of 6400 ten thousand pixels as an example, the first output mode may be a mode of outputting image data at 1600 ten thousand pixels, and the second output mode may be a mode of outputting image data at 6400 ten thousand pixels.

In step S14, the distance of the target object detected in step S12 from the mobile terminal may be compared with a distance threshold, and it may be determined whether to switch the output mode of the camera according to the comparison result. The distance threshold may be set to a fixed value by a manufacturer of the mobile terminal when the mobile terminal leaves a factory, or may be set by a user, for example, 1 meter, which is not limited by the present disclosure.

According to some embodiments of the present disclosure, if a distance of the target object from the mobile terminal is greater than a distance threshold, the output mode of the camera may be switched from the first output mode to the second output mode, and the photographed image may be output using the second output mode.

According to further embodiments of the present disclosure, if the distance of the target object from the mobile terminal is less than or equal to the distance threshold, the texture complexity of the target object may be determined from the preview image data. The texture represents the visual characteristics of the homogeneous phenomenon in the image and reflects the surface structure organization arrangement attribute with slow change or periodic change on the surface of the object.

Specifically, the average of the sum of squares of the differences between the pixel values of each pixel point and the adjacent pixel points in the target object may be calculated, and the average may be used as the texture complexity of the target object.

Other methods of calculating texture complexity, such as texture complexity analysis based on image gradients, may be envisioned by those skilled in the art. However, these schemes for calculating the complexity of the texture should fall within the scope of the present disclosure under the concept of the present disclosure.

Next, one output mode may be selected from the first output mode and the second output mode according to the texture complexity of the target object to output the photographed image.

In one case, if the texture complexity of the target object is equal to or less than a texture complexity threshold, the photographed image is output using the first output mode. The texture complexity threshold may be manually set in advance, and the disclosure does not limit specific values.

Further, in this case, it is also possible to convert the captured image output in the first output mode into an image corresponding to the pixels in the second output mode and output it. Specifically, the captured image output in the first output mode may be input into a pre-configured up-scaling (Upscale) hardware module, so as to obtain an image corresponding to the pixel in the second output mode. Still taking a camera with 6400 ten thousand pixels as an example, an image with 1600 ten thousand pixels output in the first output mode can be input into the hardware module, and an image with 6400 ten thousand pixels can be obtained and output. Therefore, the camera keeps the output of high pixels, and the output is ensured to be consistent.

In another case, if the texture complexity of the target object is greater than the texture complexity threshold, the output mode of the camera may be switched to the second output mode, and the photographed image may be output using the second output mode.

It is easily understood that the output data of the photographed image may be encoded to generate, for example, a picture in jpeg format.

The shooting processing procedure of the present disclosure will be explained below with reference to fig. 2.

In step S202, the mobile terminal may detect a distance from the target object to the mobile terminal according to preview image data output by the camera previewing in the first output mode; in step S204, it is determined whether the distance between the target object and the mobile terminal is greater than a distance threshold, if so, step S210 is performed, and if not, step S206 is performed.

In step S206, the mobile terminal may determine the texture complexity of the target object; in step S208, it is determined whether the texture complexity is greater than a texture complexity threshold, if so, step S210 is performed, and if not, step S212 is performed.

In step S210, the mobile terminal switches the output mode of the camera from the first output mode to the second output mode, and outputs the captured image.

In step S212, the mobile terminal outputs the photographed image using the first output mode; in step S214, the captured image output in step S212 using the first output mode is converted into an image corresponding to the pixels of the second output mode and output.

It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
