Camera parameter reading-writing method and apparatus as well as terminal device

The invention provides a camera parameter reading-writing method and apparatus as well as a terminal device. The method comprises the steps of reading a camera parameter class of a hardware platform by utilizing a software system interface, and obtaining character strings; analyzing the character strings to obtain all groups of the character strings; taking each group of the character strings in all the groups of the character strings as a node, and linking the nodes to obtain a data source queue; and initializing an interface menu by utilizing the data source queue for enabling the interface menu to display options containing camera parameters and camera parameter values, so that a user can perform reading-writing on the camera parameters through the interface menu. Therefore, the technical problem of incapability of performing reading-writing on specific camera parameters of each hardware platform in the prior art is solved. 本发明提供了相机参数读写方法、装置和终端设备，利用软件系统接口读取硬件平台的相机参数类，获得字符串之后，对字符串进行解析，获得各组字符串，进而将各组字符串中的每组字符
