Fig. 1 is a view of an application scenario of the flash control method in one embodiment. As shown in fig. 1, the application environment includes an electronic device 100. The electronic device 100 is provided with a camera 120 and a flash array 140, where the flash array includes at least three flashes arranged according to a preset rule. The flash array has at least two light patterns formed by at least three flashes. Supplementary lighting may be performed by the flash array 140 when the electronic device performs photographing through the camera 120. Of course, flash array 140 may also be used as a flashlight or a breathing light. Specifically, the electronic device may obtain at least two lighting modes; respectively configuring the flash lamp array into at least two lighting modes; and controlling the flash lamp array to switch between at least two lighting modes for working, thereby realizing the control of the flash lamp.
In one embodiment, a flash lamp array is provided, which includes at least three flash lamps arranged according to a preset rule; at least three flashlamps in the array of flashlamps are divided into at least two combinations of flashlamps; the flash lamp array has at least two lighting modes formed by at least three flash lamps; at least two flash lamp combinations in the flash lamp array can be switched to work between different lighting modes.
Specifically, the flash lamp array includes at least three flash lamps arranged according to a preset rule. The shape of the flash lamp array may be designed according to a position of a flash lamp reserved in the overall design of the electronic device, for example, the shape of the flash lamp array may be designed to be rectangular, elliptical, regular polygonal, circular, or the like, which is not limited in this application. At least three flash lamps can be arranged in the flash lamp array, and the number of the flash lamps in the flash lamp array is not limited in the application. Because of the different sizes of the flash lamps, the number of the flash lamps which can be arranged in the flash lamp array is different.
The at least three flash lamps in the flash lamp array are arranged according to a preset rule, and may be arranged according to the same distance and the same angle between the at least three flash lamps, and certainly, the at least three flash lamps may not be arranged according to the same distance and the same angle completely, for example, in order to adapt to the corresponding arrangement of the reserved positions of the flash lamps.
Wherein at least three flashes in the flash array are divided into at least two flash combinations. The lighting device can be divided into regular flash lamp combinations to realize regular recyclable lighting effects, and can also be divided into irregular flash lamp combinations to realize irregular recyclable and diversified lighting effects. At least three flashlamps in the flash lamp array are divided into at least two flash lamp combinations, so that each flash lamp combination can be separately controlled, for example, a switch of each flash lamp combination is separately controlled, or an electrifying parameter of each flash lamp combination is separately controlled, and the like. For example, as shown in fig. 2, a schematic structural diagram of a flash array in one embodiment is shown. The flash lamp array comprises nine flash lamps which are arranged according to a preset rule, wherein one circle in the figure represents one flash lamp, and the nine flash lamps form a square structure.

The luminance effect corresponding to the fourth mode is as shown in fig. 6(d), and only the flash combination a and the flash combination b of the flash array are operated in the fourth mode. And a 2-level current is configured for flash combination a and a 1-level current is configured for flash combination b.

And a 2-level current is configured for flash combination a and a 1-level current is configured for flash combination c.
The luminance effect corresponding to the sixth mode is as shown in fig. 6(f), in the sixth mode, only the flash combination a in the flash array is in operation, and 2-level current is configured for the flash combination a.
Several lighting modes with similar brightness effects can be screened out from the 27 lighting modes, and flash lamp combinations corresponding to the lighting modes and current parameters of the flash lamp combinations are obtained. The brightness effect can be comprehensively evaluated by calculating the central illumination and the peripheral uniformity corresponding to each lighting mode, and several lighting modes with close brightness effects can be screened out.
The flash lamp array is controlled to switch under the several lighting modes with similar brightness effect, so that the similar brightness effect can be realized. If a certain flash lamp in a certain lighting mode is damaged, the lighting mode can be automatically skipped, so that the stability of the flash lamp array is improved. If two lighting modes of the lighting modes with close brightness effects use the damaged flash lamp, and the other lighting modes do not use the damaged flash lamp, the electronic device can control the flash lamp array to switch among the other lighting modes, and automatically skip the lighting mode using the damaged flash lamp.
In the embodiment of the application, a first current parameter, a second current parameter and a third current parameter are respectively configured for each flash lamp combination, so that the flash lamp combination after current configuration is obtained. And combining the different flash lamp combinations after the current value is configured to obtain at least two lighting modes of the flash lamp array. And then the at least two flash lamp combinations in the flash lamp array can be controlled to switch between at least two lighting modes for working. Therefore, the lighting effect of one or two large traditional flashlights can be realized, meanwhile, the single flashlight can be prevented from being continuously lighted for a long time, and the service life of the flashlights is prolonged. If the switching is performed in several lighting modes with similar brightness effects, the similar brightness effects can be realized, and the difference caused by mode switching is not easy to be perceived by a user.
In one embodiment, when an odd number of flash lamps are included in the flash lamp array, dividing at least three flash lamps in the flash lamp array into at least two flash lamp combinations includes:
at least three flashes in the flash array are divided into at least one central flash combination including a flash in the center of the flash array and at least one non-central flash combination including flashes other than the central flash combination.
Specifically, in one case, when an odd number of flash lamps are included in the flash lamp array, at least three flash lamps in the flash lamp array are divided into at least two flash lamp combinations. And the divided flash lamp combinations form a central symmetrical graph by taking the central point of the flash lamp array as a symmetrical center.
Thus, at least three of the flash lamps in the flash array can be divided into at least one central flash lamp combination including the flash lamp located in the center of the flash array and at least one non-central flash lamp combination including the flash lamps except the central flash lamp combination. For example, for the nine flashlights in fig. 2, the flashlights 5 in the nine flashlights are divided into a flashlight combination a, which is a central flashlight combination. Flash 2, flash 4, flash 6, and flash 8 are divided into flash combination b, and flash 1, flash 3, flash 6, and flash 9 are divided into flash combination c. The two flash lamp combinations are non-center flash lamp combinations.
Of course, for a flash array arranged in a 5 × 5 square, the same applies to at least one central flash combination including a flash at the center of the flash array and at least one non-central flash combination including a flash other than the central flash combination. In this case, the central flash combination may be composed of only the flash lamp located at the center of the flash array, and of course, the central flash combination may also be composed of the flash lamp located at the center of the flash array and the flash lamps located in the immediate vicinity of the flash lamp. This is not limited in this application.
In another case, when even number of flash lamps are included in the flash lamp array, dividing at least three flash lamps in the flash lamp array into at least two flash lamp combinations includes: at least three flash lamps in the flash lamp array are evenly divided into at least two flash lamp combinations. I.e. the number of flashes included in each flash combination is the same.
In the embodiment of the application, when the flash lamp array comprises odd flash lamps, at least three flash lamps in the flash lamp array are divided into at least one central flash lamp combination and at least one non-central flash lamp combination, the central flash lamp combination comprises the flash lamp positioned in the center of the flash lamp array, and the non-central flash lamp combination comprises the flash lamps except the central flash lamp combination. And the divided flash lamp combinations form a central symmetrical graph by taking the central point of the flash lamp array as a symmetrical center. When the flash lamp array comprises even flash lamps, at least three flash lamps in the flash lamp array are uniformly divided into at least two flash lamp combinations. Therefore, the central illumination and the peripheral uniformity of the whole flash lamp array can be considered under different lighting modes to form uniform light.
In one embodiment, controlling the flash array to operate by switching between at least two lighting modes comprises:
under the light supplement state, controlling the flash lamp array to switch between at least two light-on modes with approximate brightness effect to work; alternatively, the first and second electrodes may be,
under the state of a flashlight, controlling the flash lamp array to switch between at least two lighting modes with similar brightness effects to work, wherein the switching time length is less than the visual delay time length; alternatively, the first and second electrodes may be,
and under the state of breathing the lamp, controlling the flash lamp array to switch between at least two lighting modes with different brightness effects to work.
Specifically, under the light supplement state, the flash lamp array is controlled to switch between at least two lighting modes with relatively close brightness effects to work. Thus, an approximate brightness effect can be achieved, making the difference caused by mode switching less noticeable to the user.
In the fill-in state, a frame of image is generally taken for fill-in once, that is, the flash array is turned on once (for a short time), and the lighting mode does not need to be switched during the fill-in period. In the flashlight state, the flash lamp array is continuously turned on (for a long time), and the mode switching is needed during the lighting period. In this case, in order to make the user less likely to perceive the difference caused by the mode switching, one of the modes is selected to switch in the mode with the brightness effect close to that of the other mode, and the switching time duration is shorter than the visual delay time duration.
And under the state of breathing the light, the control flash lamp array switches between at least two kinds of bright light modes with different brightness effects to work. Wherein, the breathing lamp means that the light gradually changes from bright to dark under the control of the microcomputer, and people feel as if breathing. The function of informing and reminding can be played through the light change of the breathing lamp. Therefore, the central illumination and the peripheral uniformity corresponding to each lighting mode can be calculated, the brightness effect can be comprehensively evaluated through the central illumination and the peripheral uniformity, the lighting modes with different brightness effects are selected, and the flash lamp array can be controlled to switch between at least two lighting modes with different brightness effects to work, so that the effect of informing and reminding is achieved through the change of the light of the breathing lamp.
In the embodiment of the application, under the light supplementing state, the flash lamp array is controlled to switch between at least two lighting modes with relatively close brightness effects to work. Thus, an approximate brightness effect can be achieved, making the difference caused by mode switching less noticeable to the user.
And in the flashlight state, the mode with the brightness effect close to that of the flashlight is selected for switching, and the switching time length is shorter than the visual delay time length. Therefore, an approximate brightness effect can be realized, a user cannot easily perceive the difference caused by mode switching, and the lighting interruption cannot be recognized by human eyes when the lighting is continuously performed.
And under the breathing lamp state, select the bright lamp mode that the luminance effect is different from above-mentioned multiple flash lamp mode, just can control the flash lamp array and switch between two kinds of bright lamp modes that the luminance effect is different and carry out work to the light change through breathing the lamp plays the effect of notice warning.
