Technical Field
The invention relates to the technical field of OLED televisions, in particular to a station caption adjusting method, an OLED television and a storage medium.
Background
An Organic Light-Emitting Diode (OLED) television is an Organic self-luminous television (RGB color signals are directly displayed by OLED diodes, and there is almost no problem of the viewing angle of liquid crystal), which does not need a backlight source.
However, the OLED television also has its own drawbacks, because it is a cable television, when the cable television is played, the position of the fixed station logo in the television program is in a static highlight state, and the fixed station logo will generate a static afterimage after being played for a long time (this is determined by the characteristics of the OLED television, because the OLED television has no backlight source, each pixel point is an LED, and when the same color is displayed at the position of the fixed station logo, the afterimage will be generated, and the color and brightness of the pixel in the area of the position of the fixed station logo are not changed for a long time, the afterimage is very easily generated). Because the picture in the television program is moving, the television screen end cannot process the fixed station caption position (fixed pixel position) in the moving picture to prevent the occurrence of the afterimage.
In order to prevent the occurrence of the residual image or to the slight residual image, the existing OLED television generally performs the residual image elimination processing (for example, current compensation is performed on the sub-pixel or the TFT device by adjusting the current) at the screen end after the television is in a standby state, and performs the residual image compensation; and meanwhile, when the video is played, the television software performs pixel shift processing on the signal image at intervals (the pixel shift is the whole television picture, and the whole image is moved to the left and moved to the right and moved to the upper and moved to the lower by a plurality of pixel positions in the display range of the television) so as to reduce the occurrence probability of the ghost.
However, the existing OLED television ghost compensation only has a function of alleviating the OLED ghost problem, and cannot completely eliminate the problem, and for a serious burned-out pixel area (an area where a still picture is displayed for a long time and a ghost appears is called a burned-out pixel area), even if the serious burned-out pixel area is compensated, the pixel drift is only a few pixel spaces to move, and a large color block and a large station mark position cannot be eliminated.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the station caption adjusting method according to the preferred embodiment of the present invention includes the following steps:
and step S10, reading the brightness parameter of the pixels of the video screen in real time, wherein the brightness parameter of the pixels of the video screen is the pixel color brightness parameter value of each pixel in the screen.
Please refer to fig. 2, which is a flowchart of step S10 in the station caption adjusting method according to the present invention.
As shown in fig. 2, the step S10 includes:
s11, reading the brightness parameter of the screen pixel of the current frame image after the screen input;
and S12, reading the brightness parameters of the video pixels of the current frame image every n frames.
Specifically, the station caption adjusting method is applied to the OLED television, the OLED television can ensure that the picture is not distorted, and can realize wide-angle viewing, the material is lighter and thinner, the television can be made to be small in size, the method is more suitable for domestic consumer markets, and the market development trend is also met.
When the OLED television is started and screen input is carried out (the screen is a television screen representing the OLED television), the brightness parameters of the pixels of the screen are read in real time through a Chip SOC (System on Chip, which means that the Chip is a product and is an integrated circuit with a special target, wherein the integrated circuit comprises a complete System and embedded software, and the brightness parameters of the pixels of the screen are pixel color brightness parameter values of each pixel in the screen, and specifically comprise display color and brightness parameters of each pixel in the screen.
Specifically, after the OLED television is normally started, the screen input is carried out, the chip SOC reads the screen pixel brightness parameters (mainly pixel color brightness parameter values) of the current frame image, and the screen pixel brightness parameters of the current frame image are continuously read after n frames are spaced.
And step S20, comparing the change of brightness parameters of the screen pixels in the screen area within the set time, and determining the fixed station caption area.
Please refer to fig. 3, which is a flowchart of step S20 in the station caption adjusting method according to the present invention.
As shown in fig. 3, the step S20 includes:
s21, comparing pixel color brightness parameter values of brightness parameters of video screen pixels in two frames of images separated by n frames, and judging whether a fixed station caption candidate area is searched;
s22, if yes, confirming the fixed station caption pixels in the fixed station caption candidate area, and judging whether the continuous occurrence frequency of the fixed station caption pixels in the fixed station caption candidate area reaches a set threshold value;
and S23, determining the fixed station caption area when the set threshold is reached.
Specifically, the change of the brightness parameters of the video pixels in the video area (i.e. the image difference of the brightness parameters of the video pixels in the video area) is compared within a set time (for example, the set time may be 30 seconds), that is, the image difference is analyzed by comparing the brightness parameters of the color of the pixels, for example, the image difference in the time period may be known by comparing the brightness parameters of the video pixels in real time or at regular time, where the image difference refers to the difference between a fixed area and a non-fixed area in the video. Further, comparing pixel color brightness parameter values of brightness parameters of video pixels in two frames of images which are separated by n frames, namely judging whether a fixed logo candidate area (the candidate area is the area of the suspected fixed logo area) appears according to the image difference.
When a fixed station caption candidate area does not appear (for example, each video or program does not have a station caption, and if a video played by connecting a television with a U disk or an APP does not have a station caption, the situation exists), continuously reading the brightness parameter of the video pixel of the current frame image after n frames of intervals and comparing the brightness parameter with the brightness parameter of the video pixel of the frame image of the previous n frames for judgment until the fixed station caption candidate area is searched.
When the fixed station caption candidate area appears, the fixed station caption candidate area is searched, the pixel position of the fixed station caption in the fixed station caption candidate area is accurately read through the chip SOC, after the interval of m frames, the chip SOC reads the brightness parameters of the fixed pixel bits in the candidate area of the fixed station logo again for comparison, judging whether the continuous occurrence frequency of the fixed station caption pixels in the fixed station caption candidate area reaches a set threshold value or not through continuous multiple comparison, namely, whether the continuous occurrence frequency of the fixed station caption pixels in the fixed station caption candidate area reaches the set threshold value N is judged, where N is a preset constant, preferably 3 ≦ set threshold N ≦ 30, for example when the set threshold N is 10, when the number of continuous occurrences of the fixed logo pixels in the fixed logo candidate region reaches 10 times, it may be determined that the fixed logo region is the fixed logo position.
Further, if the continuous occurrence frequency of the fixed station caption pixels in the fixed station caption candidate area is judged not to reach the set threshold value N, returning to the re-screen pixel analysis, and re-searching the fixed station caption candidate area.
And step S30, adjusting the pixel brightness of the fixed station caption area, and performing marginalization processing on the fixed station caption area.
Please refer to fig. 4, which is a flowchart of step S30 in the station caption adjusting method according to the present invention.

s31, reducing the pixel brightness of the fixed station caption area by a preset value;
and S32, performing marginalization processing on the fixed station caption area, weakening the boundary of the fixed station caption area, and performing screen output after integrating the adjusted pixels of the fixed station caption area with screen parameters.
Further, after the fixed station caption area is determined, in order to improve accuracy, the determined fixed station caption area may be subjected to coverage expansion processing, specifically: carrying out coverage area expansion processing on the determined fixed station caption area, and merging a plurality of preset pixels adjacent to the pixels of the fixed station caption area into the fixed station caption area to form a new fixed station caption area; (ii) a Wherein, preferably, 1 ≦ predetermined constant ≦ 50. That is, in order to prevent the missing detection of the fixed logo pixels due to the pixel drift, the coverage of the detected logo fixed pixel region is enlarged by the chip SOC, for example, several adjacent pixels (for example, 30 pixels, i.e., 1 ≦ predetermined constant ≦ 50) that identify the fixed logo pixels are all counted as the fixed logo pixels, and then the chip SOC merges these fixed logo pixels into the fixed logo region to form a new fixed logo region.
Then, the chip SOC controls the pixel brightness of the station logo area, that is, reduces the pixel brightness of the fixed station logo area (for example, reduces the brightness by half), and then performs marginalization processing on the fixed station logo area, where the image edge is an important feature of an image, and is a discontinuous part of distribution of characteristics (such as pixel gray scale, texture, and the like) in the image, and the characteristics around the image have a step change or a ridge change; most of the information of an image is concentrated in the edge part of the image, the edge structure and the characteristics of an image are often important parts for determining the image characteristics, another definition of an image edge refers to a collection of pixels whose surrounding pixels have discontinuous gray-scale variations, the edge being widely present between an object and the background, between an object and an object, therefore, the edge is an important feature of image segmentation, image understanding and image recognition, the image marginalization processing is mainly used for enhancing the contour edge, the detail and the gray level jump part in the image to form a complete object boundary, so as to achieve the purpose of separating the object from the image or detecting the area representing the surface of the same object, and finally, integrating the pixel parameters after the station caption pixel processing with the view screen parameters and outputting (namely finally outputting the adjusted view screen data).
Further, as shown in fig. 5, the whole process of detecting and adjusting the station caption in the present invention is as follows:
step S101, screen input is performed;
step S102, reading a brightness parameter of a video pixel of a current frame image, reading the brightness parameter of the video pixel of the current frame image every n frames, and comparing pixel color brightness parameter values of the brightness parameter of the video pixel in two frames of images which are separated by n frames;
step S103, judging whether a fixed station logo candidate area is searched, if so, executing step S104, otherwise, returning to execute step S102;
step S104, confirming fixed station caption pixels in the fixed station caption candidate area;
step S105, judging whether the continuous occurrence frequency of the fixed logo pixels in the fixed logo candidate area reaches a set threshold value, if so, executing step S106, otherwise, returning to execute step S102;
step S106, determining the fixed station caption area (fixed station caption position);
step S107, the coverage area of the determined fixed station caption area is expanded, and a plurality of preset constant pixels adjacent to the pixels of the fixed station caption area are merged into the fixed station caption area to form a new fixed station caption area;
step S108, reducing the pixel brightness of the fixed station caption area by a preset value, and performing marginalization processing on the fixed station caption area to weaken the boundary of the fixed station caption area;
and step S109, integrating the adjusted pixels of the fixed station caption area with the view screen parameters and then outputting the view screen.
