Abstract

The invention discloses a resolution ratio acquiring method and device of an external camera of an android system. The resolution ratio acquiring method includes acquiring all supported resolution rates of the external camera by a video driving layer, and converting the supported resolution rates of the external camera into a character string list containing resolution rate information; calling the character string list and writing the same into a camera application attribute of the android system; matching and calculating according to size of a preview interface of a camera application of the android system and the supported resolution rates of the external camera, and selecting the most matching resolution rate as resolution rate of the preview interface. By the resolution ratio acquiring method and device, different supported resolution rates of the external camera can be displayed by the camera application of the android system, the resolution rate of the external camera can be better matched with a display screen of an android system terminal, compatibility of the android system for the external camera is improved, and display effect is greatly improved.

Description

technical field [0001] The present invention relates to mobile terminal equipment, in particular to a method and device for acquiring the resolution of an external camera connected to an android system. Background technique [0002] With the popularization of mobile terminals, especially 3G smart phones, many applications are integrated on the mobile terminal, such as Internet access function, camera function and video camera function and so on. Take the terminal using the android system as an example. On the android system, the camera application has become more and more popular. Due to the limitations of the android system, when using the camera, the system itself cannot use the resolution supported by the inserted camera. To update dynamically, only fixed resolution can be supported. When different cameras are inserted, the application layer cannot obtain the resolution list supported by the currently inserted camera. The existing technology is that if the bottom layer ...
