Below in conjunction with Fig. 1 the modules of set-top box of the present invention is elaborated.
Real time operating system module 4 is the embedded OS module in implementation, and this module and is realized complicated function so that set-top box moves.In this set-top box, real time operating system module 4 is operation platforms of running environment module 3, comprising modules such as process control, storage controls.
The function of modules has been introduced separately in the front, but also interknits between these four modules.Application layer module 1 mainly is to receive the data that image engine module 2 transmits, and is applied to application program, and the feedback result of application program operation also can return to image engine module 2 and carry out associative operation; Image engine module 2 receives on the one hand from the feedback information of application layer module 1 and processes, and it is the application program operation that the result that will process on the other hand gives the upper strata; 3 operation platforms that image engine module 2 is provided of running environment module receive the operation information from image engine module 2, call simultaneously the system function of real time operating system module 4; 4 of real time operating system modules provide the system function interface of running environment module 3, receive simultaneously the operation information from running environment module 3, do relevant treatment.
Can know image engine module residing position in whole set top box embedded environment by top implementation process, and know the effect that it is brought into play in whole environment.Specifically further introduce image engine module 2 below in conjunction with Fig. 2.
Memory bus is connected with the memory of set-top box, is used for data transfer;
The central processing unit of system bus and set-top box (Central Processing Unit, CPU) links to each other, and carries out the operation of data and processes;
Image processing module is used for resolving order and the image that passes from memory bus, and output image carries out the bilateral filtering operation to suitable two-sided filter.
Fig. 2 is that the structure of image engine module of the set-top box of the embodiment of the invention forms schematic diagram, and as shown in Figure 2, memory bus mainly is responsible for data storage, and it interconnects with memory, carries out data transfer.In native system, the data of memory stores can be images, arrive image processing module by memory bus and carry out the processing of data.
Memory bus links to each other with image processing module, carries out data transfer.Data owner will comprise order data and view data, and memory bus sends order data to image processing module, and image processing module carries out the loading of order, and recognition command also carries out the operation of the corresponding command.Memory bus can send view data on the other hand to image processing module, and image processing module carries out the load operation of image, carries out the processing of image according to order, and carries out the mutual of data by the operation that writes back.
System bus links to each other with the CPU of set-top box, mainly carries out the operation of data and processes, and the speed of the CPU speed of service also will determine the efficient of whole image engine module.
Image processing module is the nucleus module in this method system, and it is to carry out the core that image is processed, from order and the image that memory bus transmits, and the operation that the parsing of process image processing module just can be correlated with.
The structure of image processing module as shown in Figure 3 forms schematic diagram, and image processing module mainly comprises image process controller, pixel operation unit, color conversion unit, pretreatment unit and two-sided filter.
Wherein, image process controller is used for resolving and carrying out the order that passes from memory bus, and carries out the loading of the loading Color Channel of pixel; The pixel operation unit is used for loading biography from the image pixel of memory bus and carries out pixel operation, sends the result after the operation to image process controller; Color conversion unit is used for loading biography from the color of image passage of memory bus and carries out the color conversion operation, sends the result after the operation to image process controller; Pretreatment unit is used for the data of carrying out after pixel operation and the color conversion are carried out preliminary treatment, and obtains pretreated data; Two-sided filter is used for that pretreated data are carried out bilateral filtering to be processed, and acquisition can be carried out the data of output display.
In image processing module, most important part is image process controller (Image processingController, IPC), is responsible for passing parsing and the execution from the order of memory bus, carrying out the loading of pixel and the work such as loading of Color Channel, is unusual part and parcel.Simultaneously, it also needs two-sided filter is selected, and output image is to suitable two-sided filter and carry out filtering operation.
The operation of pixel mainly loads and passes from the image pixel of the memory bus line operate of going forward side by side, and the result that then will operate returns to image process controller.
Color conversion mainly be responsible for to load passes from the color of image passage of the memory bus line operate of going forward side by side, and the result that then will operate returns to image process controller.
This have more intense adaptability with pixel with the method that color is separated, and no matter is that black and white or coloured image can operate by this framework.Simultaneously, because some filter processed pixels or only process color, therefore this method also is conducive to the processing of filter.
To carry out a preliminary treatment by the data after pixel operation and the color conversion, and then the result is consigned to two-sided filter carry out bilateral filtering operation.By preliminary treatment, be conducive to accelerate the bilateral filtering operation, and can obtain reasonable filter effect.
Data after processing by two-sided filter can be carried out output display, simultaneously, can come carry out the mutual of data to memory bus by writing back operation.
Implement the embodiment of the invention, the bilateral filtering technology is applied in the image engine of set-top box, then the function of enhanced machine top box image engine well can realize the application such as high definition demonstration, 3D broadcast, video conference, strengthens display effect and the image quality of Digital Television.
One of ordinary skill in the art will appreciate that all or part of step in the whole bag of tricks of above-described embodiment is to come the relevant hardware of instruction finish by program, this program can be stored in the computer-readable recording medium, storage medium can comprise: read-only memory (ROM, Read Only Memory), random access memory (RAM, Random Access Memory), disk or CD etc.
In addition, more than the set-top box based on bilateral filtering that the embodiment of the invention is provided be described in detail, used specific case herein principle of the present invention and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
