Abstract

The invention provides a method for quickly starting dual cameras, wherein the method is applied to a mobile terminal with a first camera and a second camera. The method for quickly starting dual cameras comprises the steps of receiving a dual-camera start request, controlling a main processor and a coprocessor to calibrate and configure the first camera and the second camera, controlling the main processor to respectively open the data stream of the first camera and the data stream of the second camera after the calibration and the configuration of the first camera and the second camera, and completing the startup of the dual cameras. The invention also provides a corresponding mobile terminal. Based on the method for quickly starting dual cameras, the calibration and the configuration of the first camera and the second camera are conducted mainly by means of the main processor and the coprocessor. Therefore, the consumed time of the dual cameras during the serial start-up process is reduced. The start-up speed of the dual cameras is accelerated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for quickly starting a dual camera and a mobile terminal. Background technique [0002] As users have higher requirements for the camera function of mobile terminals, more and more mobile terminals adopt the design of dual cameras. [0003] At present, the startup process of the dual cameras (for example, the first camera and the second camera) of the mobile terminal includes that the main processor performs verification and configuration on the first camera and the second camera respectively. Specifically, the main processor executes the following steps serially: first allocate the internal memory of the first camera and the second camera, and secondly, identify the IDs of the first camera and the second camera (camera identification) identification), then set the configuration parameters of the first camera and the second camera, then set the initialization par...
