Summary of the invention
The technical problem to be solved in the present invention is, causes the defective of meaningless energy consumption during at the above-mentioned broadcast rest image of existing plasm TV, and a kind of plasm TV power-economizing method and device are provided.
The present invention solves a kind of technical scheme that its technical matters adopts: a kind of plasm TV power-economizing method is provided, comprises the steps:
(a) picture signal of input is handled;
(b) judge whether described input picture is rest image, if rest image execution in step (c) then, otherwise execution in step (d);
(c) start display screen reducing power consumption pattern;
(d) display image.
In plasm TV power-economizing method of the present invention, described step (b) further comprises: whether the duration of judging a width of cloth picture in the described input picture surpasses 1 second, if then it is defined as rest image, otherwise is defined as live image.
In plasm TV power-economizing method of the present invention, described step (d) further comprises: drive display screen so that image is shown.
In plasm TV power-economizing method of the present invention, described method further comprises: continue received image signal is carried out above-mentioned judgement till the shutoff signal input.
The present invention solves another technical scheme that its technical matters adopts: construct a kind of plasm TV energy saver, described device comprises:
Be used for image is judged the rest image detection module of detection;
Be used for display screen is carried out the screen power control module of power control; And,
Be used to drive the screen driver module of display screen;
Wherein, described screen driver module and rest image detection module link to each other with the screen power control module respectively.
In plasm TV energy saver of the present invention, described screen power control module communicates to connect with the screen driver module.
In plasm TV energy saver of the present invention, described device also comprises the microprocessor that is used to coordinate each module inter-working, and described rest image detection module and screen power control module are connected with microprocessor communication respectively.
In plasm TV energy saver of the present invention, described microprocessor communicates to connect with the screen driver module.
Implement plasm TV power-economizing method of the present invention and device; has following beneficial effect: can detect screen automatically and rest image whether occur; when detecting rest image; automatically switch to the reducing power consumption pattern of screen; under the situation that the user does not discover, play effect energy-conservation and the protection screen.
Various advantage of the present invention, various aspects and character of innovation, and the details of the embodiment of example shown in it will describe in detail in following description and accompanying drawing.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structured flowchart of plasm TV energy saver one preferred embodiment of the present invention;
Fig. 2 is the flow chart of steps of plasm TV power-economizing method one preferred embodiment of the present invention.
Embodiment
Specific embodiments of the invention relate to plasm TV power-economizing method and device.The method of the invention comprises judges that to determine whether being rest image, pattern reaches energy-conservation effect with this if rest image then starts the display screen reducing power consumption to received image signal after handling to it.
Fig. 1 is the structured flowchart of plasm TV energy saver one preferred embodiment of the present invention.As shown in Figure 1, the described device of present embodiment comprises: rest image detection module 11, screen power control module 12, microprocessor 13 and screen driver module 14.
Wherein rest image detection module 11 is a corn module of the present invention, and this module determines whether it is rest image by treated input picture is judged, so that carry out subsequent operation.Concrete determination methods is as follows: when picture signal is imported, picture signal after treatment can enter into rest image detection module 11, if a width of cloth picture duration of this picture signal surpassed for 1 second, then this module can determine that it is rest image, otherwise it is considered as live image.Microprocessor 13 can receive the feedback information of rest image detection module 11 to determine the power controlling grade of screen power control module, when microprocessor 13 receives the information for still picture of being exported by the rest image detection module, just can send corresponding steering order to screen power control module 12, so that it starts display screen reducing power consumption pattern; If rest image detection module 11 is a live image information to microprocessor 13 transmissions, just then microprocessor 13 can adopt the normal frequency controlling grade by the control flow power control module.
In specific embodiments of the invention, screen driver module 14 communicates to connect with microprocessor 13, and according to the power grade information from screen power control module 12 that receives display screen is driven.
In addition, in other specific embodiments of the present invention, rest image detection module 11, screen power control module 12 and microprocessor 13 can be integrated on the chip piece, the image that this chip mainly is responsible for finishing among the present invention is judged, and the display screen power mode selects, and drives display screen according to the definite power grade of judged result and institute by coupled screen driver module.
Fig. 2 is the flow chart of steps of plasm TV power-economizing method one preferred embodiment of the present invention.Flow process starts from step 201, in step 201, the picture signal of input is handled so that carry out subsequent operation; In step 202, judge whether input picture is rest image, if a width of cloth picture duration surpassed for 1 second, judge that then it is a rest image, otherwise be live image, if rest image then flow process enter step 203 and start display screen reducing power consumption pattern, otherwise flow process skips to step 204; In step 204, drive display screen image is shown; Flow process enters step 205 subsequently, judges whether still to have picture signal input in step 205, continues input picture is judged if there is then flow process return step 201, finishes otherwise enter step 206 flow process.
