obtaining an effect gain control value according to a first environment shooting effect value of at least one first scanning image and a second environment shooting effect value of at least one second scanning image;
selecting a target scanning image from at least one first scanning image according to the effect gain control value, and setting a target environment shooting effect value of the target scanning image;
and displaying the target scanning image after the target environment shooting effect value is set on a current preview interface of the mobile terminal.
It will be understood by those skilled in the art that all or part of the steps of the above method may be performed by instructions, or by instructions controlling associated hardware, which may be stored in a computer-readable storage medium and loaded and executed by a processor. To this end, the present invention provides a storage medium, in which a plurality of instructions are stored, and the instructions can be loaded by a processor to execute the steps of any embodiment of the photo taking method provided by the present invention.
Wherein the storage medium may include: read Only Memory (ROM), Random Access Memory (RAM), magnetic or optical disks, and the like.
In order to better use the mobile terminal 100 provided in the above embodiment, so that the mobile terminal 100 processes an image according to an environment where an object to be photographed is located and an environment between the object to be photographed and the mobile terminal in a process of photographing a picture, thereby improving an effect of the photographed image, the present invention provides a picture photographing method, which is applied to the mobile terminal 100, and a flowchart of the picture photographing method is shown in fig. 3, and the specific steps may be as follows:
and a scanning step S1O1, scanning the object to be shot and the auxiliary shot object to obtain at least one first scanning image of the object to be shot and at least one second scanning image of the auxiliary shot object, wherein the distance between the object to be shot and the mobile terminal is greater than the distance between the auxiliary shot object and the mobile terminal.
It is easy to understand that, during the image scanning process of the mobile terminal, an auxiliary shooting object between the object to be shot and the mobile terminal is determined, and a second scanned image of the auxiliary shooting object is obtained through scanning, so that when the first scanned image of the object to be shot is processed subsequently, the image data of the second scanned image is used for comparison.
And an obtaining step S1O2, obtaining an effect gain control value according to a first environment shooting effect value of at least one first scanning image and a second environment shooting effect value of at least one second scanning image.
It is understood that, in the embodiment, the second scanned image is used as a reference image, and the effect gain control value indicates a deviation value between the first environmental capture effect value of the first scanned image and the second environmental capture effect value of the second scanned image used as the reference image, and the effect gain control value determines a manner of subsequent adjustment of the first scanned image by the mobile terminal.
It should be noted that, when the mobile terminal scans a plurality of first scanned images and a plurality of second scanned images, the average value is obtained by performing weighted calculation on a plurality of first environment photographic effect values of the plurality of first scanned images, the average value is obtained by performing weighted calculation on a plurality of second environment photographic effect values of the plurality of second scanned images, and then the subsequent calculation step is performed.
For example, the obtaining step S1O2 may specifically include:
a first calculation substep, performing weighted calculation on the first environment shooting effect value according to a first preset formula to obtain a first average environment shooting effect value, and performing weighted calculation on the second environment shooting effect value according to the first preset formula to obtain a second average environment shooting effect value;
and a second calculation substep of dividing the first average environmental photographic effect value by the second average environmental photographic effect value to obtain an effect gain control value.
It is easily understood that the effect gain control value is greater than 1 and less than 1, which correspond to the first environmental capture effect value of the first scanned image being higher and lower than that of the second scanned image.
And a selecting and setting step S1O3, selecting a target scanning image from at least one first scanning image according to the effect gain control value, and setting a target environment shooting effect value of the target scanning image.
It should be noted that, in order to reduce power consumption generated when the terminal performs subsequent image adjustment, when there are multiple first scanned images, the terminal selects one first scanned image with the first environmental capture effect value closest to the second environmental capture effect value of the second scanned image as a target scanned image according to the calculated effect gain control value, and then performs image adjustment.
For example, the selecting and setting step S1O3 may specifically include:
a first selection substep of selecting a first scanned image corresponding to a first environment shooting effect value with the minimum value as a target scanned image when the effect gain control value is greater than 1;
and a second selection substep of selecting the first scanned image corresponding to the first environmental shooting effect value with the largest value as the target scanned image when the effect gain control value is smaller than 1.
It is easily understood that, when the effect gain control value is greater than 1, it means that the first environmental capture effect value of the first scanned image is higher than that of the second scanned image, and therefore, of the plurality of first scanned images, the first scanned image closest to the second environmental capture effect value of the second scanned image is the image with the lowest value of the first environmental capture effect value; when the effect gain control value is smaller than 1, it means that the first environmental imaging effect value of the first scanned image is lower than that of the second scanned image, and therefore, the first scanned image closest to the second environmental imaging effect value of the second scanned image among the plurality of first scanned images is the image with the highest value of the first environmental imaging effect value.
It should be noted that, after the target scan image is selected and the magnitude relationship between the effect gain control value and 1 is determined, the target environment shooting effect value of the target scan image may be set.
For example, the selecting and setting step S1O3 may further include:
a reduction setting substep of setting a target environment photographic effect value of the target scanned image to be a product of a first environment photographic effect value with a minimum value and an effect gain control value;
and an enhancement setting substep, setting the target environment shooting effect value of the target scanning image to be the product of the first environment shooting effect value with the maximum value and the effect gain control value.
It will be readily appreciated that the reduction setting sub-step is a step subsequent to the first selection sub-step and the enhancement setting sub-step is a step subsequent to the second selection sub-step.
And a display step S1O4, displaying the target scanning image after the target environment shooting effect value is set on the current preview interface of the mobile terminal.
It is easy to understand that, when displaying an image, the mobile terminal may select to only occupy a portion of the terminal display screen to display the target scanned image after the target environment shooting effect value is set, for example, 50% of the terminal display screen is occupied for image display, and the remaining 50% of the terminal display screen is used for providing an image editing key for a user of the mobile terminal to modify and beautify the image.
It should be noted that, when the position of the object to be photographed changes, the mobile terminal needs to scan again to determine the object to be photographed, and then photograph the object.
For example, after the step S1O4 is displayed, the method further includes:
a detection step of detecting that the position of an object to be shot changes;
returning to the execution step, returning to the execution scanning step S1O1.
Different from the prior art, the invention provides a photo shooting method which is applied to a mobile terminal and comprises the following steps: performing image scanning on an object to be shot and an auxiliary shooting object to obtain at least one first scanning image of the object to be shot and at least one second scanning image of the auxiliary shooting object, wherein the distance between the object to be shot and the mobile terminal is greater than the distance between the auxiliary shooting object and the mobile terminal; obtaining an effect gain control value according to a first environment shooting effect value of at least one first scanning image and a second environment shooting effect value of at least one second scanning image; and then, the target scanning image after the target environment shooting effect value is set is displayed on a current preview interface of the mobile terminal, so that the mobile terminal can process the image according to the environment of the object to be shot and the environment between the object to be shot and the mobile terminal in the process of shooting the picture by the mobile terminal, and the effect of the shot image is improved.

It is understood that, in the embodiment, the second scanned image is used as a reference image, and the effect gain control value indicates a deviation value between the first environmental capture effect value of the first scanned image and the second environmental capture effect value of the second scanned image used as the reference image, and the effect gain control value determines a manner of subsequent adjustment of the first scanned image by the mobile terminal.
It should be noted that, when the mobile terminal scans a plurality of first scanned images and a plurality of second scanned images, the average value is obtained by performing weighted calculation on a plurality of first environmental photographic effect values of the plurality of first scanned images, the average value is obtained by performing weighted calculation on a plurality of second environmental photographic effect values of the plurality of second scanned images, and then the subsequent calculation step is performed.

the first calculating subunit 21 is configured to perform weighted calculation on the first environment shooting effect value according to a first preset formula to obtain a first average environment shooting effect value, and perform weighted calculation on the second environment shooting effect value according to the first preset formula to obtain a second average environment shooting effect value;
the second calculating subunit 22 is configured to divide the first average environmental capture effect value by the second average environmental capture effect value to obtain an effect gain control value.
It is easily understood that the effect gain control value is greater than 1 and less than 1, which respectively correspond to the first environmental capture effect value of the first scanned image being higher and lower than that of the second scanned image.
(3) Selection and setting module 30
A selecting and setting module 30, configured to perform a selecting and setting step S103, namely, selecting a target scanned image from the at least one first scanned image according to the effect gain control value, and setting a target environment shooting effect value of the target scanned image.
It should be noted that, in order to reduce power consumption generated when the terminal performs subsequent image adjustment, when there are multiple first scanned images, the terminal selects one first scanned image with the first environmental capture effect value closest to the second environmental capture effect value of the second scanned image as a target scanned image according to the calculated effect gain control value, and then performs image adjustment.
Further, referring to fig. 5, the selecting and setting module 30 may specifically include:
a first selecting subunit 31, configured to select, when the effect gain control value is greater than 1, a first scanned image corresponding to a first environmental shooting effect value with a smallest value as a target scanned image;
the second selecting sub-unit 32 is configured to select the first scanned image corresponding to the first environmental shooting effect value with the largest value as the target scanned image when the effect gain control value is smaller than 1.
It is easily understood that, when the effect gain control value is greater than 1, it means that the first environmental capture effect value of the first scanned image is higher than that of the second scanned image, and therefore, of the plurality of first scanned images, the first scanned image closest to the second environmental capture effect value of the second scanned image is the image with the lowest value of the first environmental capture effect value; when the effect gain control value is smaller than 1, it means that the first environmental imaging effect value of the first scanned image is lower than that of the second scanned image, and therefore, the first scanned image closest to the second environmental imaging effect value of the second scanned image among the plurality of first scanned images is the image with the highest value of the first environmental imaging effect value.
It should be noted that, after the target scan image is selected and the magnitude relationship between the effect gain control value and 1 is determined, the target environment shooting effect value of the target scan image may be set.
For example, the selection and setting module 30 may further include a fade setting unit and an boost setting unit, wherein:
the attenuation setting unit is used for setting a target environment shooting effect value of the target scanning image to be the product of a first environment shooting effect value with the minimum value and an effect gain control value;
the enhancement setting unit is used for setting the target environment shooting effect value of the target scanning image to be the product of the first environment shooting effect value with the maximum value and the effect gain control value.
It will be readily appreciated that the reduction setting unit is connected to the first selection subunit 31 and the enhancement setting unit is connected to the second selection subunit 32.
(4) Display module 40
And the display module 40 is configured to perform the display step S104, that is, display the target scanning image after the target environment shooting effect value is set on the current preview interface of the mobile terminal.
It is easy to understand that, when displaying an image, the mobile terminal may select to display the target scanned image after the target environment shooting effect value is set by only occupying a part of the terminal display screen, for example, the terminal display screen occupying 50% displays the image, and the remaining 50% of the terminal display screen is used to provide an image editing key for a user of the mobile terminal to modify and beautify the image.
It should be noted that, when the position of the object to be photographed changes, the mobile terminal needs to scan again to determine the object to be photographed, and then photograph the object.
For example, the photo capture device further comprises a detection module for:
after a target scanning image with a set target environment shooting effect value is displayed on a current preview interface of the mobile terminal, detecting that the position of an object to be shot changes;
the scanning step S101 is executed back.
