And through the hue value and the skin color saturation, the skin color parameter of the target character is more comprehensively extracted.
The calculation module is used for calculating the first difference value and the second difference value between the first skin tone value and the second skin tone value and between the first skin tone value and the third skin tone value respectively; after the extraction module obtains the skin tone value of the target character, the calculation module calls a function, data corresponding to the first skin tone value and the second skin tone value are brought into a calculation formula, difference values between the first skin tone value, the second skin tone value and the third skin tone value are further calculated, and difference values between the first skin tone value, the second skin tone value and the third skin tone value are calculated. Namely, the skin color difference between the first target person, the second target person and the third target person is judged.
The comparison module compares the first difference value and the second difference value with the preset threshold value; after the calculation is completed, the comparison module further compares the calculated first difference value and the calculated second difference value with a preset threshold value arranged in the intelligent terminal. Wherein, the first difference value and the second difference value are both an absolute value; the preset threshold value is a standard for measuring the difference between the first skin tone value, the second skin tone value and the third skin tone value.
The receiving module is used for receiving the photographing instruction;
when a user needs to shoot a current preview image, a shooting instruction is sent to the intelligent terminal, and the shooting instruction comprises: single, double click, long press, swipe, etc. And after receiving a photographing instruction sent by a user, the receiving module executes photographing and captures a preview image displayed in the current interface.
When the first difference value and the second difference value are both greater than the preset threshold value, the exchanging module randomly exchanges the first skin tone value of the first target character, the second skin tone value of the second target character and the third skin tone value of the third target character according to the photographing instruction to generate the updated image.
In the process of executing the photographing instruction by the intelligent terminal, the exchange module further obtains a comparison result of the first difference value and the second difference value which are calculated in advance and a preset threshold value. When the first difference value and the second difference value are both larger than a preset threshold value, namely, the comparison module judges that the skin colors of the first target character, the second target character and the third target character are different to a certain degree, the exchange module executes a photographing instruction and further exchanges numerical codes corresponding to the first tone value, the second tone value and the third tone value at will so as to realize the skin colors of the first target character, the second target character and the third target character at will and generate an updated image. In the updated image, the first skin tone value is applied to the second target person or the third target person, the second skin tone value is applied to the first target person or the third target person, and the third skin tone value is applied to the second target person or the third target person.
Preferably, the exchanging module is further in communication connection with the extracting module, and further exchanges the skin tone value of the target person and further exchanges the skin tone saturation of the target person.
In order to ensure that the skin color after the swapping is completely consistent with the skin color in the preview image, and more truly restore the skin color between the swapping target objects, the numerical code swapped by the swapping module in this embodiment further includes a numerical code representing the saturation of the skin color of the target person.
Preferably, the photographing system further comprises a storage module;
the storage module is in communication connection with the comparison module and the receiving module;
and when the difference value is smaller than or equal to the preset threshold value, the storage module stores the preview image according to the photographing instruction.
In a preferred embodiment, the photographing system further comprises a storage module, and the storage module is in communication connection with the comparison module and the receiving module. When the comparison module judges that at least one of the first difference value and the second difference value is smaller than or equal to a preset threshold value, namely, the difference between at least two of the first skin tone value, the second skin tone value and the third skin tone value is smaller, the exchange module does not execute skin tone exchange, and after the receiving module receives a photographing instruction, the storage module stores the preview image in the intelligent terminal according to the photographing instruction.
By adopting the photographing method and the photographing system based on the intelligent terminal, provided by the invention, the skin color value of the target person in the preview image can be extracted, and when the difference of the skin color values among the target persons is larger than a preset threshold value, the skin color values of the target persons are automatically exchanged, so that the skin color exchange among the target persons is realized, and the interestingness of photographing is further increased.
It should be noted that the embodiments of the present invention have been described in terms of preferred embodiments, and not by way of limitation, and that those skilled in the art can make modifications and variations of the embodiments described above without departing from the spirit of the invention.
