Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

An anti-candid apparatus 100 for an electronic device according to an embodiment of the first aspect of the present application is described below with reference to the drawings.

Referring to fig. 1 and 2, according to the anti-candid apparatus 100 for an electronic device according to an embodiment of the first aspect of the present application, the electronic device 200 includes a body portion 210 and a controller, and the anti-candid apparatus 100 may include: the camera module 1.

Specifically, the camera module 1 may be provided on the body part 210, the camera module 1 is electrically connected to the controller, and the camera module 1 includes: a laser transmitter 11 and a laser receiver 12. The laser transmitter 11 may be used to emit laser light outwards (e.g. towards the target object 2); the laser receiver 12 is used for receiving the laser light reflected by the target object 2 to the laser receiver 12.

When a preset shooting instruction is detected, the power of the laser transmitter 11 is increased to acquire the current environment information. For example, the pre-shooting instruction here may be that the user prepares to shoot with the anti-candid device 100 in the present application to detect whether a candid device exists in the surrounding environment. The power of the laser emitter 11 may be controlled by the controller, and the controller may increase the power of the laser emitter 11 according to the current environment information, so as to make the emitting distance of the laser longer.

And judging whether object information with the matching degree with preset object information larger than a preset threshold exists in the current environment information. For example, the current environment information refers to information of a detected surrounding environment, the preset object information may be standard information for comparison pre-stored when a candid camera exists in the surrounding environment, and the preset threshold may be adaptively set as needed.

And if the target object information with the matching degree larger than the preset threshold exists, sending indication information aiming at the target object information. For example, by comparing the current environment information with the preset object information, if the matching degree of the current environment information and the preset object information is greater than the target object information of the preset threshold, sending indication information 3 for the target object information, and using the indication information 3 to remind a user that there may be candid equipment around the user.

According to some embodiments of the present application, the target object 2 may be, for example, a candid camera or the like. The candid camera device can be a candid camera or a candid camera and the like. When the candid camera exists in the surrounding environment, the anti-candid camera 100 for the electronic equipment according to the embodiment of the application can send the indication information aiming at the candid camera to the user, so that the personal privacy can be ensured.

The camera module 1 is a system structure composed of a projector and a camera, for example, a structured light camera group. The projector is used for projecting specific light information to the surface of an object and the background, and the specific light information is collected by the camera. The projector of the structured light is generally a laser emitter, and the emission distance of the laser can be further increased through power adjustment. When the laser irradiates the candid camera, the cat eye effect appears on the surface of the camera, and the camera can be identified.

According to the anti-candid camera device 100 for the electronic device in the embodiment of the first aspect of the present application, when a preset shooting instruction is detected, the power of the laser emitter 11 of the camera module 1 is increased to collect current environmental information; judging whether object information with the matching degree with preset object information larger than a preset threshold exists in the current environment information or not; and if the target object information with the matching degree larger than the preset threshold exists, sending indication information aiming at the target object information. The indication information can remind the user that the candid photographing device possibly exists around the user.

In the algorithm, a "detection mode" can be added to the photographing function, after the mode is entered, the page of the electronic device 200, such as a mobile phone, is similar to a video page, the mobile phone automatically increases the laser emission power, when a suspicious target object appears in front of the lens, the mobile phone screen is similar to a 'recognized face' during photographing, and the suspicious target object is actively highlighted. At this time, the user can further confirm whether the suspicious target object is the candid shooting device.

In some embodiments of the present application, the preset shooting instruction is a spy mode provided on the electronic device 200. For example, the electronic device 200 may have a reconnaissance mode, and the preset shooting instruction may be provided on the electronic device 200.
