Here, it can be understood that each flash lamp can emit light only by power supply, each flash lamp can be set with corresponding control switch, and the on and off of the control switch can be controlled by a processor of the terminal; the implementation manner of the control switch may be various, and the embodiment of the present invention is not limited.

Here, the driving current of the flash lamp means a current input to the flash lamp, and the driving voltage of the flash lamp means a voltage across the flash lamp; it is understood that the light emission luminance of the flash lamp is enhanced when the driving current or the driving voltage is increased, whereas the light emission luminance of the flash lamp is weakened.

In an alternative example, an adjustable resistor may be provided in the power supply circuit of the flash lamp, and the increase of the driving current or the driving voltage of the flash lamp is controlled by the adjustable resistor, and the resistance value of the adjustable resistor may be controlled by the processor of the terminal.

Step 302: and receiving the adjusted flash lamp parameters.

In actual implementation, when a terminal user adjusts the flash lamp parameters, the adjusted flash lamp parameters can be input to the terminal through a user input unit of the terminal, so that a processor of the terminal can acquire the adjusted flash lamp parameters.

Step 303: and when a shooting instruction is received, controlling the first flash lamp and the second flash lamp to emit light according to the adjusted parameters of the flash lamps.

Here, the photographing instruction may be an instruction generated by clicking a photographing button of the photographing interface.

Optionally, the terminal user may adjust the flash lamp parameter for multiple times, display an expected shooting effect during each adjustment, and determine that the current adjusted flash lamp parameter is the final flash lamp parameter when the terminal user determines that the expected shooting effect meets the requirement; therefore, parameters of the flash lamp can be freely adjusted according to actual requirements, and the shooting effect is improved.

It should be noted that the scheme described above by adjusting the light emission of the two flash lamps is only an exemplary scheme, and the embodiment of the present invention does not limit the number of flash lamps; when the number of the flash lamps is greater than 2, the above-mentioned scheme of adjusting the light emission of the two flash lamps can be referred to, and details are not described here.

The method for adjusting the supplementary lighting of the terminal comprises the following steps of firstly, when the camera of the terminal is determined to work, displaying prompt information, wherein the prompt information is used for prompting a terminal user to adjust parameters of a flash lamp, and the parameters of the flash lamp comprise: the driving parameters of the first flash lamp and the second flash lamp are driving current or driving voltage; then, receiving the adjusted parameters of the flash lamp; and finally, when a shooting instruction is received, controlling the first flash lamp and the second flash lamp to emit light according to the adjusted parameters of the flash lamps. Therefore, for various shooting environments, the parameters of the flash lamps can be adjusted according to the user instruction, and shooting is further performed based on the adjusted parameters of the flash lamps, so that the embodiment of the invention can be suitable for various shooting environments, and the shooting effect of the current shooting environment can be improved.

Second embodiment

In order to further embody the object of the present invention, the first embodiment of the present invention is further illustrated.

The process of the light supplement adjusting method for the terminal according to the second embodiment of the present invention may include:

step A1: acquiring captured image history data including: n flash parameters and N shot images; the N captured images include: an image is taken based on each of N flash parameters, N being an integer greater than 1.

That is, N flash parameters each including a driving parameter of the first flash and a driving parameter of the second flash may be determined in advance; determining N flash lamp parameters, and determining a driving parameter value every first set interval from the minimum value to the maximum value of the driving parameter of the first flash lamp; determining a driving parameter value every second set interval from the minimum value to the maximum value of the driving parameter of the second flash lamp; and randomly combining each driving parameter value corresponding to the first flash lamp with each driving parameter value corresponding to the second flash lamp to obtain a plurality of flash lamp parameters.

For example, the driving parameters of the first flash lamp and the second flash lamp are driving currents, the minimum value of the driving current of each flash lamp is 150mA, and the maximum value of the driving current of each flash lamp is 900 mA; at this time, the driving current of the first flash lamp is 150mA to 900mA, and the driving current of the second flash lamp is 150mA to 900mA, and the parameters of the flash lamps are obtained by taking 10mA as intervals respectively.

In practical implementation, the first set interval and the second set interval can be set according to actual requirements, and when the values of the first set interval and the second set interval are smaller, the number N of the obtained flash lamp parameters is larger; conversely, when the values of the first set interval and the second set interval are large, the number N of the derived flash lamp parameters is small.

Step A2: similar to the implementation of step 301, the detailed description is omitted here.

Step A3: the implementation manner is the same as that of step 302, and is not described herein again.

Step A4: when the adjusted flash lamp parameters are received, when the flash lamp parameters matched with the adjusted flash lamp parameters exist in the shot image historical data according to a preset matching rule, obtaining a specific shot image in the shot image historical data; wherein the specific shot image is: and shooting images corresponding to the flash lamp parameters matched with the adjusted flash lamp parameters.

Illustratively, the preset matching rule may include:

the difference value of the adjusted flash lamp parameter and the driving parameter of the first flash lamp of any flash lamp parameter in the historical data of the shot image is smaller than a first set threshold value; and,

For example, the driving parameter is a driving current, and in the adjusted parameters of the flash lamps, the driving current of the first flash lamp is 352mA, and the driving current of the second flash lamp is 505 mA; in one flash lamp parameter of the historical data of the shot image, the driving current of a first flash lamp is 350mA, and the driving current of a second flash lamp is 510 mA; the first set threshold and the second set threshold are 7mA, and at the moment, flash lamp parameters matched with the adjusted flash lamp parameters in the shot image historical data are determined according to a preset matching rule.

Fig. 6 is a schematic diagram of a user input interface according to an embodiment of the present invention, and as shown in fig. 6, a terminal displays "please input a first setting threshold and a second setting threshold", and provides a corresponding input box and a determination button.

For the acquisition mode of the specific shot image, in one example, shooting may be performed in advance based on each flash lamp parameter in the shot image history data, to obtain each shot image of each flash lamp parameter in the shot image history data, that is, in the shot image history data, the correspondence between the shot image and the flash lamp parameter is determined; thus, when the flash parameter matching the adjusted flash parameter is determined, the specific shot image can be easily determined.

Step A5: and displaying the specific shot image.

In actual implementation, the current preview photographing screen may be replaced with a specific photographing image.

Here, the effect of showing the specific shot image is: the end user is enabled to determine whether the specific shot image meets the requirement, for example, by determining whether the specific shot image has defects such as dark, bright or low contrast.

Optionally, when the user determines that the specific shot image does not meet the requirement, the flash lamp parameter may be adjusted again, so that the specific shot image corresponding to the current flash lamp parameter may be displayed again;

when the user judges that the specific photographed image satisfies the requirement, the current adjusted flash parameters are determined to be the final flash parameters, and step a6 is performed.

Step A6: the implementation manner is the same as that of step 303, and is not described herein again.

Optionally, parameters of the flash lamp corresponding to various ambient color temperature parameters may be predetermined;

that is, for different ambient color temperature parameters, corresponding flash lamp parameters are set; the set parameters of the flash lamp need to ensure that a better shooting effect can be obtained when shooting is carried out on the corresponding ambient color temperature parameters; in practical implementation, the flash parameters of various ambient color temperature pairs can be determined by shooting at various ambient color temperature parameters.

It can be seen that, in the embodiment of the present invention, it may be first determined whether a flash lamp parameter matching the adjusted flash lamp parameter exists in the captured image history data, and then, a mode of adjusting the flash lamp parameter is selected according to the determination result, that is, whether a user directly inputs the adjusted flash lamp parameter or determines the adjusted flash lamp parameter according to the current ambient color temperature parameter is selected, so that the light supplement adjustment mode may be flexibly determined.

It can be understood that, when matching is performed according to a preset matching rule, if the matching success rate needs to be increased, the value of N may be increased, for example, the value of N may be 1000.
