Camera module control method and device based on WIFI (Wireless Fidelity) network

Abstract

The invention provides a camera module control method and device based on a WIFI (Wireless Fidelity) network. The method comprises the steps of detecting whether a master MIPI (Mobile Industry Processor Interface) frequency employed by a currently working camera module carries out co-channel interference on a WIFI channel or not when it is detected that terminal equipment in the WIFI network starts a camera function and it is determined that an application scene of the camera function belongs to a video communication scene, starting a frequency hopping mechanism when it is detected that a channel of the master MIPI frequency carrying out the co-channel interference on the WIFI channel is a video communication channel of the application scene, and controlling the camera module to switch toa preset backup MIPI frequency. Under the condition of not influencing a video, the master MIPI frequency is hopped to a frequency which is not overlapped with a WIFI frequency, the co-channel interference of the camera module on a WIFI antenna in the video communication scene under the WIFI of a user is solved, and the hardware cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a camera module control method and device based on a WIFI network. Background technique [0002] Video chatting has become very popular at present. Under the condition of Wireless Fidelity (WIFI), users generally like to use mobile phone video chatting. However, since the camera module and WIFI antenna are basically located on the top of the mobile phone, the mobile industry processing The MIPI (Mobile Industry Processor Interfac, MIPI) frequency and its multiplier frequency have great interference to WIFI. Domestic 2.4G WIFI has only 13 channels, if there is interference, it will have a great impact on users. [0003] In related technologies, there are generally two ways to solve the interference problem between the camera module and the WIFI antenna. One way is hardware shielding measures, which prevent interference by spraying electromagnetic interference (Elec...

Problems solved by technology

The software MIPI frequency movement must refer to the recommended MIPI frequency range of the IC in the module. At the same time, the MIPI frequency change is also closely related to the imaging effect. In order to achieve the perfect rendering effect of the rear camera, the camera module will not be able to move after the MIPI frequency is changed. However, when performing video communication through WIFI, the network speed of the WIFI network is inconsistent with the video quality, and a single MIPI frequency appears to be contradictory in the composite scene of WIFI video calls, and the user's video call experience is not good.
