Abstract
The invention discloses a method to intelligent eliminating ghost. It includes the following steps: digitalizing the image processing signal; judging the image whether static according to the image signal; judging the last display time span whether exceeding the preset value; if the span time exceeding the preset value, supplying light emitting function recovering chance for the imate. Thus, the light emitting function of the high brightness area would maintain longer, and because naked eye is not sensitive to the small and slow change of location and brightness, it doesn't influence the visual effect and can effectively decrease the chance of having ghost. Thus, the using life of the monitor would be prolonged.
Description
[technical field]:
The present invention relates to a kind of intelligence and eliminate the method for ghost.
[background technology]:
The long-time width of cloth still frame that shows of all display devices, the capital causes the regional luminous efficacy of long-time exhibit high brilliance little by little to be lower than the zone of long-time demonstration low-light level, in the course of time, when showing other pictures, just see the afterimage of former still frame, can be referred to as the still image ghost phenomena, or burn and iron phenomenon (burn in).This phenomenon ratio of some display device (as plasma display PDP, CRT projection cathode-ray tube, the reflective panel LCOS of monocrystalline silicon) is easier to take place.How to lower the chance of occurrence of ghost, be a technical matters that needs to be resolved hurrily the serviceable life that prolongs display device.
[summary of the invention]:
Purpose of the present invention is exactly in order to solve the problem that above rest image can produce ghost, to provide a kind of intelligence to eliminate the method for ghost.
The present invention realizes that the scheme of above-mentioned purpose is: a kind of intelligence is eliminated the method for ghost, it is characterized in that, comprises the steps: 1) the digitized processing picture signal; 2), judge whether this image is still frame according to picture signal; 3) judge that whether the lasting demonstration time of this still frame is above predetermined value T
04) if the lasting demonstration time of this still frame surpass predetermined value T
0, then intermittence is recovered chance for this rest image provides luminous efficacy.Describedly the mode that luminous efficacy recovers chance is provided pixel back and forth moves at a slow speed in order to adopt, the brightness circulation slowly reduces enhancings, one of multiple processing mode such as white scroll bar circulating rolling, intermittence display reminding language etc. handles picture signal.
Adopt the beneficial effect of above scheme: because adopt that pixel back and forth moves at a slow speed, the brightness circulation slowly reduces enhancings, one of multiple processing mode such as white scroll bar circulating rolling, intermittence display reminding language etc. handles picture signal, intermittently recover chance for image provides luminous efficacy, it is much permanent to make the luminous efficacy of high-brightness region to keep; Simultaneously, because the variation of human eye position and brightness to the trickle of image and slowly is very insensitive, therefore video vision effect not, and reduced the chance of occurrence of ghost effectively, prolonged the serviceable life of display device greatly.
[description of drawings]:
Fig. 1 is a theory diagram of the present invention.
Fig. 2 is a process flow diagram of the present invention.
[embodiment]:
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
It is that long-time accumulation forms that the present invention utilizes still image ghost phenomena (burning irons phenomenon), as long as intermittence provides luminous efficacy to recover chance, the luminous efficacy of high-brightness region can be kept much permanent; And very insensitive this two specific character of variation of human eye position and brightness to the trickle of image and slowly and in conjunction with the high-speed computation ability of integrated circuit proposes the method that a kind of effective intelligence is eliminated ghost, as shown in Figure 1, 2, comprises the steps:
1) digitized processing picture signal;
2), judge whether this image is still frame according to picture signal;
3) judge that whether the lasting demonstration time of this still frame is above predetermined value T
0
4) if the lasting demonstration time of this still frame surpass predetermined value T
0, then intermittence is recovered chance for this rest image provides luminous efficacy.
Step 2 wherein) judge that whether this image is that the method for still frame is: each is represented with 8 bits with R, the G of each pixel, B, if R, G, B value have only the bit and the previous moment of hanging down 3 that conversion is arranged, it is static then to look this pixel; If it is still frame more than or equal to static then this image of pixel in the scope of 20 row * 20 row that this image has arbitrary.
Wherein the step 4) discontinuous for the step that rest image provides luminous efficacy to recover chance is:
If 4-1) the lasting demonstration time of this still frame is greater than predetermined value T
0, be made as a few minutes, then just do the reciprocal mobile at a slow speed mode of the pixel of discovering least easily earlier and recover luminous efficacy, promptly pixel is just to move one or several pixel every a period of time, gets back to original point left to the right, upwards,, downwards as the whole elder generation of shielding; If 4-2) the lasting demonstration time of this still frame is greater than predetermined value T
1, promptly surpass half an hour, the mode that then adopts brightness slowly to reduce, brightness was that one-period slowly reduces to recover luminous efficacy with per ten minutes; If 4-3) the lasting demonstration time of this still frame is greater than predetermined value T
2, surpass one hour, then adopt the mode of white scroll bar circulating rolling to recover luminous efficacy, the luminous situation that white scroll bar can the forcibly changing pixel at this moment, though image is subjected to the interference of white scroll bar, can also show and watch; If 4-4) the lasting demonstration time of this still frame is greater than predetermined value T
3, surpass two hours, then adopt the mode of display reminding language at intermittence to remind the user to change signal or shutdown, if not reaction of user, then shutdown automatically in 20 minutes.
Step 2) judge in this image whether be still frame method can also for: the static degree of still image factor fs presentation video is set, image is divided into several macro blocks, each macro block can be a pixel or several composition, each macro block and macro block on every side and front and back field constantly compares computing, draws continuous intravenous as factor fs.Be made as A such as R, G, the weighting of B value or not weighted array (ratio of each weighting coefficient can be 1: 1: 1, also can decide according to actual conditions) with each pixel, | A
T+1-A
t| represent that each pixel changes the fs=1/ ∑ in the brightness of adjacent moment
n 0| A
T+1-A
t| the static degree of presentation video regional extent, with fs and S
0Compare, if still image factor fs is greater than predetermined value S
0Judge that then this image is a still frame.
S wherein
0Be the data of under long-term experiment, verifying out, different display screens is had different data, for example: the S of 42V2 screen
0Be 0x3A.
If still image factor fs is smaller or equal to predetermined value S
0, and continue to show a period of time, promptly continue the demonstration time greater than predetermined value T
0, the probability that forms the still image ghost is very little, and picture intelligence does not need directly to deliver to display device through handling and shows; If still image factor fs is greater than predetermined value S
0, but continue the demonstration time smaller or equal to predetermined value T
0, the probability that forms the still image ghost is also very little, and picture intelligence is directly delivered to display device without processing and is shown.
