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 invention discloses an online detection device for incense string filter sticks, and specifically relates to the technical field of cigarette detection. This includes an image acquisition module, a control module and a touch display screen. The image acquisition module includes two sets of detection heads and a mounting bracket. The two sets of detection heads are respectively fixed on the mounting brackets, and are respectively facing the end face of the incense wire filter rod to be tested for image acquisition. The detection head includes a light source, an industrial camera, an optical lens and a transparent window group. The image acquisition module simultaneously collects the images of the two end faces of the incense wire filter rod to be tested through the industrial camera and sends them to the control module after preliminary processing. The control module controls the image acquisition module. The collected images are processed to determine whether there are defects such as missing incense thread and center position deviation in the incense filter rod, and output a shutdown alarm or rejection signal according to the judgment result, and the touch display is used to display operating information and set parameters. Prevent unqualified products from flowing into the packaging link from the source, reduce material consumption, and reduce production costs.

Embodiments of the present invention provide a photographing method and a mobile terminal, which relate to the field of communication technology, and solve the problem of poor supplementary light effect in the existing photographing method. Wherein, the shooting method includes: displaying a preview image on the first screen of the mobile terminal, acquiring subject brightness information, background brightness information, and white balance information of the preview image; , determine the brightness of the supplementary light; determine the color temperature of the supplementary light according to the white balance information; and control the second screen of the mobile terminal to emit bright light according to the brightness of the supplementary light and the color temperature of the supplementary light. The photographing method in the embodiment of the present invention is applied to a mobile terminal.

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.

The invention discloses an iris recognition device, a recognition method and a light supplementing method with a supplementary light function. The device comprises: a collection module for collecting human eye images; When setting the definition, send a control signal to the supplementary light module; the supplementary light module is arranged on one side or both sides of the acquisition module, and is used to rotate according to the control signal, so that the optical axis of the supplementary light module is aligned with the human body. In the eye area, the angle range of the rotation is within 37-53 degrees, and the angle range is the angle range between the optical axis of the supplementary light module and the line formed by the connection between the supplementary light module and the acquisition module.
