The invention discloses an intelligent LED (light-emitting diode) video synchronizing impulse stroboscopic supplemental lighting device. The device is composed of an electronic circuit and a shell, wherein the electronic circuit has the following structure: a 220V alternating current is connected with a 24V switching power supply and a synchronization generator, the 24V switching power supply is connected with an LED lamp matrix and a +12V power supply circuit, the +12V power supply circuit is connected with a +5V power supply circuit, a light ray detection circuit is connected with a signal processing circuit, a signal input circuit is connected with the signal processing circuit, the signal processing circuit is connected with a signal output circuit, and the signal output circuit is connected with the LED lamp matrix through an actuator. With the adoption of the device provided by the invention, the phenomena of dazzling, uneven exposure and streaking can be effectively avoided, the synchronous exposure with a frame of a camera and frequency multiplication output of light can be realized, and the problem that the color of the red light in an image shot by a monitoring camera changes from red to yellow during the red light signal of traffic lights is solved.

The disclosure relates to a supplementary light device, a calibration method, a device, a storage medium and a device for supplementary light, and relates to the field of image acquisition technology. The supplementary light device includes: at least two first supplementary lights, and at least two second supplementary lights For the lamp and the lens, the color temperature of the first supplementary light and the color temperature of the second supplementary light are different, and the lens covers at least two first supplementary lights and at least two second supplementary lights according to a preset positional relationship , so that the light emitted by at least two first supplementary lights and at least two second supplementary lights can pass through the lens, the first current is applied to at least two first supplementary lights, and the at least two second supplementary lights A second current is applied to the lamp to adjust the central bright spot of the supplementary light device by controlling the first current and the second current, and the central bright spot is the position with the highest color temperature in the light emitted by the supplementary light device. It can improve the yield efficiency of production, reduce costs, and can evenly fill light and improve the fill light effect.

The invention relates to the technical field of electronics, and discloses a light supplementing method in photographing based on screens and electronic equipment. In the invention, the light supplementing method in photographing based on the screens comprises the following steps: providing a light supplementing selection screen when a command of opening a front camera is received, wherein the light supplementing selection screen comprises a plurality of preset light supplementing items; when a user selects one of the preset light supplementing items, receiving the preset light supplementing item selected by the user and acquiring a light supplementing picture corresponding to the preset light supplementing item; when a photographing command is received, displaying the light supplementing picture continuously on the screens at preset duration, and photographing pictures within the preset duration. According to the light supplementing method in photographing based on the screens and the electronic equipment provided by the invention, when the front camera is used for photographing, the eyes are not dazzled and the light supplementing is uniform, and various scenes can be simulated to perform light supplementing and photographing; in addition, the light supplementing cost is lower, and the appearance beauty of the equipment can be improved.
