Method for collecting image through optical accessory and terminal equipment

The embodiment of the invention discloses a method for collecting an image through an optical accessory and terminal equipment, is applied to the technical field of terminal equipment, and can solve the problems that in the prior art, when terminal equipment obtains data in a microscope or a microphone or other devices, special devices need to be configured, the implementation complexity is high, and the cost is high. A camera is arranged on a first surface of the terminal device, an optical accessory is arranged on the outer side of the camera on the first surface, so that the camera collects an imaging picture of the optical accessory, and the method comprises the following steps: detecting a first distance between the optical accessory and the camera; if the first distance is smaller than the first preset distance, starting a target application program corresponding to the optical accessory on the terminal equipment; and acquiring an imaging picture of the optical accessory through the camera to obtain a t
