Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, clear and definite, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 1, Fig. 1 is the flow chart of preferred embodiment of the processing method of a kind of LCD TV moving image of the present invention compensation.
Step S110 presets motion picture refresh cycle threshold value, and with this motion picture refresh cycle threshold value storage that sets.
For example, the user is when using LCD TV to watch image with motion picture, the user can set motion picture refresh cycle threshold value in advance by the mode of remote controller or panel button, and this motion picture refresh cycle threshold value that will set stores the LCD TV that the user opens into.Enter thus step S120.
Step S120, when the operational order that receives the user is opened LCD TV moving image compensate function, then the sheet source category of current broadcast is obtained in control, and whether judges in the current picture motion picture and have that the lamp switch frequency is higher than described predefined motion picture refresh cycle threshold value in a certain viewing area.
Namely when setting by remote controller or panel button, the user opens LCD TV moving image compensate function, preset and stored picture refreshing cycle threshold value through above step S110 again, so, when liquid crystal television system receives the user and opens the operational order of LCD TV moving image compensate function, then LCD TV can at first be controlled and obtain in progress source category of current LCD TV, namely whether belongs to the TV programme with motion picture; And whether continue to judge in the current picture motion picture, and to judge whether that especially the switching frequency of lamp in a certain viewing area is higher than predefined motion picture refresh cycle threshold value noted earlier; And continuation enters step S130 thus.
Step S130, when judging that current picture is that the lamp switch frequency is higher than described predefined motion picture refresh cycle threshold value in motion picture and a certain viewing area, then being identified as motion picture needs compensation model.
Judge that by the step S120 of front the switching frequency that obtains having in the in progress picture of current LCD TV lamp in a certain viewing area is higher than motion picture refresh cycle during threshold value that sets in advance storage, so, just current in progress tv programme picture is identified as motion picture needs compensation model to liquid crystal television system in this step S130, enters step S140 at this.
Step S140 needs compensation model when being identified as motion picture, then controls the current picture refreshing cycle is adjusted into described predefined motion picture refresh cycle threshold value.
In this step, because current in progress tv programme picture is identified as motion picture needs compensation model, then system's control is adjusted into described predefined motion picture refresh cycle threshold value with the current picture refreshing cycle, be that system is reduced to the current picture refreshing cycle motion picture refresh cycle threshold value that has arranged, namely by the Intelligent Recognition of system to motion picture, minimizing motion picture demonstration frame number reaches and promotes clearness, picture is unlikely to refresh too fast like this, avoids conditions of streaking.
The processing method of described LCD TV moving image compensation wherein, also comprised before described step S110: arrange one for the menu item of opening LCD TV moving image compensate function in LCD TV in advance.
Because common LCD TV does not arrange and uses compensate function before this, so, as realizing above each step procedure, so just need to arrange one for the menu item of opening LCD TV moving image compensate function in LCD TV in advance, to make things convenient for the user whether selecting opening movement image compensation function, thereby when watching the motion class television image for the further realization of user by LCD TV, motion picture is clear and smooth more.
The processing method of described LCD TV moving image compensation, wherein, described source category comprises: motion class program and competitive sports.
Because the user is when the TV programme of using LCD TV to receive to watch with motion picture, be mainly motion class program and competitive sports, and the characteristics of these programs to be reproduction times mostly be that one section or segmentation continue the long time, therefore, mainly be the sheet source category of motion class program and competitive sports in the processing method of selecting the compensation of application LCD TV moving image.
The processing method of described LCD TV moving image compensation, wherein, described lamp is the LED lamp.
Mentioned lamp switch frequency in a certain viewing area among the step S120 in front, wherein the lamp here is mainly the LED lamp that uses in the LCD TV.
Fig. 2 is the flow chart of the concrete Application Example of a kind of LCD TV moving image of the present invention processing method of mending.As shown in Figure 2, the present invention describes as an example of a kind of LCD TV example, and then the flow chart of this embodiment may further comprise the steps:
Step S310, user normally start LCD TV, make it be in normal operating conditions, and then the user opens LCD TV moving image compensate function by remote controller or panel button by the methodological function entrance of LCD TV motion compensation, and then changes step S320 over to.
Step S320, user are that default meets the LCD TV threshold value of a usual better motion picture refresh cycle of playing by remote controller or panel button.Enter step S330.
Step S330 when the user sets this better motion picture refresh cycle threshold value that meets the LCD TV normal play for system after, sends operational order to system the motion picture refresh cycle threshold value adding system that this sets in advance is stored; And enter step S340.
Step S340, according to above-mentioned steps S310, S320, S330, system will obtain the above default and storing moving picture refresh cycle threshold value of finishing this moment, and will identify the in progress picture of active user's liquid crystal TV set according to above the setting, mainly the program source classification of current broadcast is distinguished, determine whether to belong to motion class program or competitive sports, will enter so step S350 and judge.
Whether step S350 has in this judges the motion picture of LCD TV that the refresh cycle has surpassed the threshold value that presets storage in the scope of certain viewing area, if the judgment is No, then continues to return recognition detection; If the judgment is Yes, then enter next step S360 and continue to finish corresponding function setting.
Step S360, because having judged, previous step S350 obtain having in the motion picture the interior refresh cycle of certain viewing area scope to surpass the threshold value that presets storage, at this moment, the threshold value of current refresh cycle is set by system, make it to meet the refresh cycle requirement of motion picture, corresponding promoting clearness.Then enter step S370.
Step S370 has finished smoothly that by above-mentioned steps the threshold value that meets the current motion picture refresh cycle being set, and then withdraws from thus the function system of LCD TV motion compensation.
Therefore, the processing method of a kind of LCD TV moving image compensation that the embodiment of the invention provides, by system motion pattern Intelligent Recognition, minimizing motion picture demonstration frame number reaches and promotes clearness, thereby so that motion picture clear and smooth more, reach the ghost of removing the previous frame image, the effect that improves dynamic definition, the degree that human eye is difficult to perception is down in the image hangover, also reduced energy consumption.
