Abstract
The invention discloses a video image enhancement method applied to players. The method includes the steps: step 1, adopting a video image detection unit of a player to monitor definition of video images, and when a low-illuminance video image in the video images is detected, extracting the indistinct video image; step 2, subjecting the low-illuminance video image to enhancement, namely extracting a luminance component and a reflection component of a frame of image in the video, calculating an illuminance component of the image according to the luminance component and the reflection component, enhancing the illuminance component, and calculating the luminance component of the image according to the new information of the enhanced illuminance component; step 3, acquiring image parameters according to the calculated new luminance component of the image, calculating enhancement parameters of the image, and reconstructing the image to obtain an enhanced image; step 4, by the same means, subjecting the next frame of image of the video images to image enhancement and image reconstruction until enhancement of the whole indistinct video image is realized.
Description
Technical field
The present invention relates to a kind of video image enhancing method be applied in player.
Background technology
No matter be often need to use video player to play video in teaching or office, realize the object of presentization office and teaching.But in the process of carrying out video playback, often there is the unsharp phenomenon of video image, make user need repeatedly to play video and again watch, waste so very much the time of user.Therefore we adopt video image processing technology to process video image.And the video and graphic disposal route of prior art needs a lot of step mostly when processing video image, based on multiple computing method, take a long time the enhancing that just can realize video image, and strengthen after image still clear not.
Summary of the invention
According to prior art Problems existing, the invention discloses a kind of video image enhancing method be applied in player, comprise the following steps:
Step 1: the video images detection unit installed on a player is monitored the sharpness of video image in real time, when the low-light (level) image in video image being detected, extracts this unsharp video image;
Step 2: carry out strengthening process to above-mentioned low-light (level) video image: the luminance component and the reflecting component that extract a two field picture of this video, its luminance component is calculated according to luminance component and reflecting component, luminance component is strengthened, according to the luminance component of the new illumination component information computed image after enhancing;
Step 3: the new luminance component according to this two field picture calculated obtains image parameter, calculates the enhancing parameter of this two field picture, rebuilds this two field picture, the image after being enhanced;
Step 4: in the manner described above, carries out image enhaucament and image reconstruction until realize the enhancing of whole unintelligible video image to the next frame image of this video image.
When carrying out strengthening calculating luminance component to the luminance component of image: the product equaling reflecting component and luminance component according to luminance component calculates.
The described genetic algorithm that adopts when strengthening luminance component realizes the enhancing of luminance component.
Adopt the video image enhancing method be applied in player disclosed by the invention, sharpness process is carried out to the video image play in player, brightness enhancing and image reconstruction are carried out to the video image in player, finally realizes the sharpness process of video.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the process flow diagram of the inventive method.
Embodiment
For making technical scheme of the present invention and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear complete description is carried out to the technical scheme in the embodiment of the present invention:
The video image enhancing method be applied in player as shown in Figure 1, comprises the following steps:
Step 1: the video images detection unit installed on a player is monitored the sharpness of video image in real time, when the low-light (level) image in video image being detected, extracts this unsharp video image;
Step 2: carry out strengthening process to above-mentioned low-light (level) video image: the luminance component and the reflecting component that extract a two field picture of this video, its luminance component is calculated according to luminance component and reflecting component, luminance component is strengthened, according to the luminance component of the new illumination component information computed image after enhancing;
Step 3: the new luminance component according to this two field picture calculated obtains image parameter, calculates the enhancing parameter of this two field picture, rebuilds this two field picture, the image after being enhanced;
Step 4: in the manner described above, carries out image enhaucament and image reconstruction until realize the enhancing of whole unintelligible video image to the next frame image of this video image.
Further, when carrying out strengthening calculating luminance component to the luminance component of image: the product equaling reflecting component and luminance component according to luminance component calculates.
Further, the described genetic algorithm that adopts when strengthening luminance component realizes the enhancing of luminance component.
The video image enhancing method be applied in player disclosed by the invention, the unclear video image carrying out playing can be extracted at short notice, image enhaucament and image reconstruction process are carried out to each two field picture of this video image, finally obtains video image clearly.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
Claims (3)
