In, the mapping relations can carry out Initialize installation when terminal is dispatched from the factory, and be stored in the memory function module of terminal, work as user
When needing to use the mapping relations, directly acquiescence mapping relations are selected to set by interactive interface, for example, by ring when terminal is dispatched from the factory
In mapping relations between border brightness value and the rotary speed of rotatable camera are stored in terminal system by mapping table
In depositing.In another embodiment, the acquisition of the mapping relations includes the interactive interface by terminal, and it is bright that user is manually entered environment
Mapping relations between angle value and the rotary speed of rotatable camera, it is stored in the internal memory in terminal system.Again
In one embodiment, the acquisition of the mapping relations can be obtained by way of network share, and terminal is carried out into network connection,
The mapping relations searched between the ambient brightness value and the rotary speed of rotatable camera, will be certainly by way of network share
The mapping relations list of definition or document are uploaded to network share to other people, or mapping relations are downloaded by way of network share
List or document.
, can be by setting reflecting between ambient brightness value and the rotary speed of rotatable camera using the embodiment of the present invention
Relation is penetrated, during the rotatable camera of terminal is rotated, when the image that rotatable camera photographs is colour
During image, the coloured image is converted into gray level image, calculates the mean flow rate of gray level image or presetting for gray level image
The mean flow rate in region, and as ambient brightness value, by the environment for the image for photographing current rotatable camera
Compared with difference between brightness value and the ambient brightness value for the image that its former frame rotatable camera photographs, with adjustment
The rotary speed of rotatable camera, realize more accurately speed carry out rotary taking, finally control rotatable camera
Rotated according to the rotary speed after adjustment, improve image quality, improve the effect of shooting.
One of ordinary skill in the art will appreciate that realize all or part of flow in above-described embodiment method, being can be with
The hardware of correlation is instructed to complete by computer program, described program can be stored in a computer read/write memory medium
In, the program is upon execution, it may include such as the flow of the embodiment of above-mentioned each method.Wherein, described storage medium can be magnetic
Dish, CD, read-only memory (Read-Only Memory, ROM) or random access memory (Random Access
