Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the primary camera shooting of Android system framework, be divided into from top to bottom: application layer 11, ccf layer 12, hardware abstraction layer 13 and driving layer 14, usually by Binder, call back function or system call contact, described driving layer 14 contacts by I/O control command and hardware device between layers.Described ccf layer 12 comprises the Parameter(parameter) function module 121, described hardware abstraction layer comprises Camera Parameter module (camera parameter) 131 and CameraHal interface 132.
The present invention is under the primary camera shooting of the existing Android system as shown in figure mono-framework, makes improvement, realizes the adjusting to the image quality attribute.
Fig. 2 shows the realization flow of a kind of camera image quality control method based on the android platform that the embodiment of the present invention 1 provides, and details are as follows:
Concrete, application layer receives user's image quality and regulates request, the adjusting parameter value that described request comprises image quality attribute and described image quality attribute, described image quality attribute comprises contrast, brightness, saturation etc., described adjusting parameter value comprises that the user regulates fixed number value really is set by application program.
Application layer receives user's image quality regulate request after, the image quality attribute that comprises in described request and the adjusting parameter value of image quality attribute are sent to ccf layer.
Preferably, in the Parameter of ccf layer module (parameter module) 121, create the first interface module, described first interface module is interface function module (such as the setControlParamete function module), described interface function module is transmitted two parameters, one is the image quality attribute, and one is the adjusting parameter value that the user arranges.Described interface function receives the adjusting parameter value of described image quality attribute and image quality attribute.Parameters setParameters module in the development hardware level of abstraction in the CameraHal interface, the attribute information of the hardware camera that needs are regulated adds in this function.Described first interface module, by calling the parameters module of described expansion, is transferred to hardware abstraction layer by the adjusting parameter value of described image quality attribute and described image quality attribute.
The described image quality attribute of step 203, the transmission of hardware abstraction layer sink block rack-layer and the adjusting parameter value of described image quality attribute, and it is transferred to and drives layer.
Preferably, in the camera parameter Camera of camera hardware abstraction layer Parameter module, create the first sign (such as the KEY_XXX_VALUE sign) and the first module (such as the getControlParameterValue function module).Be transferred to the image quality attribute of hardware abstraction layer and the adjusting parameter value of described image quality attribute by described the first sign indicia framing rack-layer, described the first sign is what in the camera parameter Camera of hardware abstraction layer Parameter module, to create.The parameters module of described expansion is obtained the image quality attribute of described the first sign institute mark and the adjusting parameter value of described image quality attribute by calling described the first module.Driving layer to create the second module (such as the v4l2SetControl function module), the parameters module of described expansion is again by calling the second module that drives layer, and the adjusting parameter value of the image quality attribute of described the first sign institute mark of obtaining and described image quality attribute is transferred to and drives layer.
Drive layer to receive the described image quality attribute of hardware abstraction layer transmission and the adjusting parameter value of described image quality attribute by the second module, and the described image quality attribute of hardware camera is adjusted to the adjusting parameter value of described image quality attribute, thereby complete the adjusting of the image quality attribute that camera is obtained.
