Description

Shooting method and related equipment Technical Field The application relates to the technical field of terminals, in particular to a shooting method and related equipment. Background Currently, electronic devices such as mobile phones and tablet computers are equipped with cameras, and users can trigger the electronic devices to shoot images, record videos and the like through the cameras. In addition to the camera, a switching power supply is usually disposed on a main board of the electronic device, and the switching power supply can be used for converting the voltage output by a battery of the electronic device into the voltage required by the corresponding functional module during operation, wherein the functional module comprises a loudspeaker, a display screen, a microphone and the like. However, when shooting by a camera, some switching power supplies are easy to become interference sources, and image quality is affected, so that a dark stripe phenomenon occurs in an image. Disclosure of Invention The application provides a shooting method and related equipment, which can solve the problem that some switching power supplies are easy to cause dark stripes of images when shooting through a camera. The technical scheme is as follows: in a first aspect, a photographing method is provided and applied to an electronic device, and the method includes: And under the condition that the target switching power supply is started, matching the CDS frequency of the first camera with the switching frequency of the target switching power supply in the starting process of the first camera, so that the CDS frequency and the switching frequency of the target switching power supply are in a frequency multiplication relationship, and the target switching power supply is an interference source of the first camera. Illustratively, the first camera is camera a, which is the primary camera. In this way, by matching the CDS frequency with the switching frequency of the switching noise to cancel the switching noise in the CDS system calculation process, the phenomenon that the image appears black streaks due to the switching noise of the switching power supply is improved without increasing the cost. As an example of the present application, matching the CDS frequency of the first camera with the switching frequency of the target switching power supply includes adjusting the CDS frequency according to the switching frequency of the target switching power supply in the case where the number of the target switching power supplies is one, and adjusting the switching frequencies of the plurality of target switching power supplies according to the CDS frequency in the case where the number of the target switching power supplies is a plurality. In this way, according to the number of target switching power supplies, it is determined to adjust the CDS frequency or adjust the switching frequency of the target switching power supplies so that the CDS frequency matches the switching frequency of the target switching power supplies without affecting the operation of the target switching frequency as much as possible. As an example of the present application, in the case where the number of the target switching power supplies is one, adjusting the CDS frequency according to the switching frequency of the target switching power supplies includes multiplying the switching frequency of the target switching power supplies by a preset value to obtain a first CDS frequency in the case where the number of the target switching power supplies is one, and adjusting the CDS frequency to the first CDS frequency. Therefore, the CDS frequency and the switching frequency of the target switching power supply are in a multiplied frequency relationship, so that switching noise can be eliminated in the calculation process, and the aim of inhibiting the switching noise is fulfilled. As an example of the present application, in case that the number of the target switching power supplies is plural, adjusting the switching frequencies of the plural target switching power supplies according to the CDS frequency includes multiplying the values of the CDS frequency by different preset values, respectively, to obtain plural target switching frequencies, each of which is within a preset switching frequency range, in case that the number of the target switching power supplies is plural, and adjusting the switching frequencies of the plural target switching power supplies based on the plural target switching frequencies. Therefore, the switching frequency of each target switching power supply can be respectively adjusted to different values according to the requirements, and the switching frequency of each adjusted target switching power supply is in a preset switching frequency range, so that the output stability of the target switching power supply is ensured. As an example of the application, the first camera is controlled to be mapped when the target switching po
