Abstract
The invention discloses a method capturing intelligent television pictures. The method capturing intelligent television pictures comprises the following steps: receiving picture capture requests; judging whether the television is performing picture capture operation or not, if performing, then performing waiting till confirming that the television is not performing picture capture operation; correlating input video signals and a core video space, starting conversion of the core video space to the video signals, and locking the video signals; inquiring a corresponding core video space corresponding to picture data capture requirement mapping according to data size of the core video space; and dynamically applying an internal memory in a user space and completing data copy from a core space to the user space. The method capturing intelligent television pictures can achieve capture pictures which users interest in under the condition of not increasing complete machine cost and can conveniently perform performance optimization and change.
Description
Technical field
The invention belongs to the digital image processing techniques field, be specifically related to the method that a kind of intelligent TV set picture is caught.
Background technology
Along with the development of Intelligent flat TV tech and the increase of audio frequency and video information source quality and quantity, the information that the user can obtain also increases thereupon at present.When the user sees interested information, for satisfying personalized demand, the demand that picture is caught has in real time been proposed.
In traditional television set, way adopts hardware mode usually, is finished by television set microprocessor controls external module or control chip build-in function module the data of image data acquisition and conversion are processed, and the interested picture of user is caught.
Making arranges in pairs or groups to hardware in this way certain requirement, namely can increase certain complete machine cost, and because the curing of particular hardware function can only be carried out the performance adjustment to open adjustment parameter, therefore is not easy to optimization and the change of performance.
Summary of the invention
Technical problem to be solved by this invention is: propose the method that a kind of intelligent TV set picture is caught, can realize catching of to user picture interested in the situation that do not increase the complete machine cost, solve that picture in the conventional art catches that cost is high, the technological deficiency of the optimization of performance and change inconvenience.
The present invention solves the problems of the technologies described above the technical scheme that adopts:
The method that a kind of intelligent TV set picture is caught may further comprise the steps:
Receive picture and catch request;
Judge whether television set is carrying out picture and catching operation, if just wait for, until confirm
Television set does not carry out picture and catches operation;
Incoming video signal and kernel sdi video are associated, open the kernel sdi video to the conversion of this vision signal, and lock this vision signal;
Size of data inquiry and view data intercepting to the kernel sdi video require kernel sdi video corresponding to mapping;
In user's space, dynamically apply for internal memory and finish kernel spacing to the data copy of user's space.
The invention has the beneficial effects as follows: because this method is to adopt the software kernel of intelligent TV set to carry out picture to catch, therefore overcome the dependence to the specific hardware module, saved this part hardware cost.Simultaneously, because therefore the flexibility that can utilize software inhouse parameter and programmed algorithm to adjust can carry out optimization and the change of performance easily.
Description of drawings
Fig. 1 is flow chart of the present invention.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, the method that a kind of intelligent TV set picture is caught may further comprise the steps:
Receive picture and catch request;
Judge whether television set is carrying out picture and catching operation, if just wait for, until confirm that television set does not carry out picture and catches operation, namely adopt the mutex mechanism of control to solve the multithreading stationary problem;
In the present embodiment, intelligent TV set has adopted the operating system based on Linux, therefore safeguard that under Linux one deck kernel memory headroom is as sdi video, incoming video signal and kernel sdi video are associated, open the kernel sdi video to the conversion of this vision signal, and lock this vision signal;
Size of data inquiry and view data intercepting to the kernel sdi video require kernel sdi video corresponding to mapping;
In user's space, dynamically apply for internal memory and finish kernel spacing to the data copy of user's space.
Realize obtaining of view data by above step, then can take following steps to realize coding and the preservation of view data are processed:
View data is carried out color space transformation and to the view data processing of encoding, in the present embodiment, color space transformation is to be transformed into yuv format from rgb format;
The data and the corresponding packing header that encode are saved in the memory device of television set together.
In the processing procedure of whole view data, picture signal is carried out the Lock locking, and after the release of waiting for, unsuccessfully return, finish dealing with, then picture signal is carried out Unlock and separate locking.
The present invention adopts the kernel transformation of the way and the software algorithm to Linux, has broken away from the dependence to the specific hardware module, does not therefore need to increase independent hardware cost.
The software implemented process can realize performance optimization and change at an easy rate, as: by changing compression ratio and changing quantization table and coding schedule, can better compress data; By changing software algorithm, can realize compressing to the support of new picture format with according to new picture format.
Process by coding and preservation to view data, the picture of catching can with intelligent TV set in the signal environment effective integration, generate suitable carrier chrominance signal form and video coding and storage form, so that the application of subsequent expansion function, for example the user can be presented at the picture of storing on the start-up picture as personalized Logo after the image-region storage is specified in crawl.
