Detailed Description
In order to make the purpose, technical solution and advantages of the present application more clearly and clearly understood, the technical solution in the embodiments of the present application will be described below in detail and completely with reference to the accompanying drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the embodiment of the present invention, the term "display device" may also be referred to as a display, or may be referred to as a display screen or a screen in a popular manner. Is an apparatus that can output an image.
When the display device displays an image, the problem of the difference of the visual angles exists, so that two Gamma tables act on sub-pixels of the displayed image according to a preset sample plate in a space domain, and the problem of the difference of the visual angles is improved by using the pixel space brightness average on the premise of not influencing a front visual angle Gamma curve, as shown in fig. 1.
Wherein, two Gamma tables are respectively: the first Table, also called H Table, is shown in fig. 2; the second Table, also called L Table, is shown in fig. 3.
In the present application, the pixel signs of two adjacent sub-pixels in the preset template are different, and the preset template includes two pixel signs, which are respectively a first sign, also called as H sign, and a second sign, also called as L sign; fig. 4 is a schematic diagram of a default template in the present application.
In one possible implementation, the "H" and "L" flags may also be replaced with "1" and "0", where the first Table is again the "1" Table; the second Table is also "0" Table, so those skilled in the art can use various forms for naming two Gamma tables and two pixel flags, and details are not described herein.
When the luminance processing is performed on the images of consecutive frames in the spatial domain, each frame of image performs the luminance processing on the image according to the pixel flag in the preset template, so that the sub-pixels at the same position use the same Gamma Table for the luminance processing, as shown in fig. 5. Therefore, when the display displays images, the display condition that sub-pixels are alternately bright and dark occurs, and a graininess feeling is generated.
At present, the balance problem of visual angle and granular sensation in the related technology is mutually sacrificed according to different requirements, for example, if the visual angle of a wide visual angle is required to be larger, the granular sensation is sacrificed; on the contrary, if the granular sensation is weak, the viewing angle is relatively small.
In order to realize the balance problem of visual angle and granular sensation, namely, reduce the granular sensation of image display and improve the quality of displayed images while improving the problem of image distortion caused by narrow side viewing angle, the method provides two Gamma tables which are switched in an airspace and a time domain, realizes the brightness balance of the airspace and the time domain, realizes the brightness average in the airspace and improves the side viewing angle; the brightness is averaged in the time domain, the granular sensation is eliminated, and the image quality of a displayed image is improved.

As shown in fig. 6, a method for displaying an image according to an embodiment of the present application includes:
step 600, determining the pixel mark of each sub-pixel in the display image, wherein the pixel marks of two adjacent sub-pixels in the same frame of display image are different, and the pixel marks of the sub-pixels at the same position in the two adjacent frames of display image are different.
In the present application, the TCON control board determines the pixel flag of each sub-pixel in the display image according to the preset template.
In the present application, if the first sub-pixel in the first row in the preset template is the first mark (H mark), the second sub-pixel in the first row is the second mark (L mark), the third sub-pixel in the first row is the first mark, the fourth sub-pixel in the first row is the second mark, and so on;
the first sub-pixel in the second line is the second mark, the second sub-pixel in the second line is the first mark, the third sub-pixel in the second line is the second mark, the fourth sub-pixel in the second line is the first mark, and so on;
the pixel flag order of each sub-pixel in the third row is the same as the pixel flag order of each sub-pixel in the first row, and the pixel flag order of each sub-pixel in the fourth row is the same as the pixel flag order of each sub-pixel in the second row, as shown in detail in fig. 4.
Of course, in the present application, it is also possible to provide: the first sub-pixel in the first row is the second mark, the second sub-pixel in the first row is the first mark, the third sub-pixel in the first row is the second mark, the fourth sub-pixel in the first row is the first mark, and so on;
the first sub-pixel in the second row is the first mark, the second sub-pixel in the second row is the second mark, the third sub-pixel in the second row is the first mark, the fourth sub-pixel in the second row is the second mark, and so on. That is, the set pixel flag is opposite to the pixel flag of each sub-pixel shown in fig. 4, and the description of the drawings will not be used here.
If the first frame image in the present application determines the pixel flag of each sub-pixel in the display image according to the preset template, at this time:
the first sub-pixel in the first row is a first mark, the second sub-pixel in the first row is a second mark, the third sub-pixel in the first row is a first mark, the fourth sub-pixel in the first row is a second mark, and so on;
the first sub-pixel in the second row is the second mark, the second sub-pixel in the second row is the first mark, the third sub-pixel in the second row is the second mark, the fourth sub-pixel in the second row is the first mark, and so on.
In the present application, the second frame image determines the pixel flag of each sub-pixel in the display image according to the target sample, the target sample is determined according to the preset sample, the pixel flag of the sub-pixel at the same position in the target sample is different from the pixel flag of the sub-pixel at the same position in the preset sample, and at this time, the pixel flag of the sub-pixel at the same position in the second frame image is different from the pixel flag of the sub-pixel at the same position in the first frame image.
In the second frame image:
the first sub-pixel in the first row is the second mark, the second sub-pixel in the first row is the first mark, the third sub-pixel in the first row is the second mark, the fourth sub-pixel in the first row is the first mark, and so on;
the first sub-pixel in the second row is the first mark, the second sub-pixel in the second row is the second mark, the third sub-pixel in the second row is the first mark, the fourth sub-pixel in the second row is the second mark, and so on.
Therefore, when a plurality of frames of images are displayed continuously, the pixel marks of two adjacent sub-pixels in the same frame of display image are different, and the pixel marks of the sub-pixels at the same position in the two adjacent frames of display image are different.
In the present application, the Gamma Table includes a first Table and a second Table. When the first Table is set to process the sub-pixels, the brightness of the sub-pixels is increased; and when the second Table processes the sub-pixels, the brightness of the sub-pixels is reduced.
In the present application, after the pixel flag of the sub-pixel is determined, when the luminance processing is performed on the display image by the preset Gamma Table according to the pixel flag of the sub-pixel:
if the pixel mark corresponding to the sub-pixel in the display image is the first mark, processing the brightness of the sub-pixel corresponding to the first mark through the first Table;
and if the pixel mark corresponding to the sub-pixel in the display image is the second mark, processing the brightness of the sub-pixel corresponding to the second mark through the second Table.
In the present application, the first Table and the second Table of the Gamma Table are determined as follows:
predefining a first Table and a second Table;
performing brightness processing on the image according to a preset sample plate through a first Table and a second Table which are designed in advance;
the method comprises the steps of setting a preset sample plate, carrying out brightness processing on a first sub-pixel by adopting a first Table, carrying out brightness processing on a second sub-pixel by adopting a second Table, after carrying out brightness processing on each sub-pixel in a display image, determining whether the brightness value of the processed image meets a preset brightness value or not based on a brightness tool, adjusting the first Table and the second Table if the brightness value does not meet the preset brightness value, carrying out brightness processing on each sub-pixel in the display image again by adopting the adjusted first Table and the adjusted second Table until the brightness value of the processed image meets the preset brightness value, and determining the first Table and the second Table when the preset brightness value is met as the first Table and the second Table in the Gamma Table.
Note that the brightness tool of the present application is CA 310.
As shown in fig. 7, for a schematic diagram of image display provided in the embodiment of the present application, it can be known from fig. 7 that the brightness of two adjacent sub-pixels in the spatial domain is different, so that the brightness averaging is achieved, and the side viewing angle is improved; different Gamma tables are adopted on the sub-pixels at the same position in two adjacent frames of images in the time domain, so that the brightness is averaged, the granular sensation is eliminated, and the image quality of the displayed image is improved.
Therefore, when the image after brightness processing is displayed, the sub-pixels on each frame of image in the spatial domain are alternately processed by adopting the first Table and the second Table, and the sub-pixels at the same position on the continuous multi-frame image in the time domain are switched by adopting the first Table and the second Table, so that the phenomenon of insufficient charging of the sub-pixels is caused, as shown in fig. 8, when the first curve is that the second Table is switched to the first Table, the target brightness value cannot be directly reached when the image is displayed due to insufficient charging of the pixels; the second curve is that when the second Table is switched to the first Table, the OD factor is increased, so that the target brightness value can be reached immediately when the next frame image is displayed.
As shown in fig. 9, when the first curve is that the first Table is switched to the second Table, the target brightness value cannot be directly reached when the image is displayed due to insufficient charging of the pixels; the second curve is that when the first Table is switched to the second Table, the OD factor is increased, so that the target brightness value can be reached immediately when the next frame image is displayed.
In the present application, the OD factor is determined according to the correspondence between the pixel values of the sub-pixels of the two adjacent frames of display images and the OD factor, and the correspondence may be stored in the form of a table, as shown in fig. 10.
In the application, when the OD factor is determined according to the corresponding relationship between the pixel values of the sub-pixels of the two adjacent frames of display images and the OD factor, if the pixel values of the sub-pixels of the two adjacent frames of display images are not stored in the corresponding relationship, two pixel values close to the pixel values are searched in the corresponding relationship, and the OD factor is determined according to the two close pixel values.
For example, the pixel value of the sub-pixel of the previous frame display image is 88, and the pixel value of the sub-pixel of the current frame display image is 96; as can be seen from the correspondence relationship in fig. 10: the pixel value 88 is not included in the pixel values of the sub-pixels of the display image of the current frame, and therefore the pixel values of the sub-pixels of the display image of the previous frame are determined to be 80 and 96. At this time, according to the pixel value of the sub-pixel of the previous frame display image being 80 and the pixel value of the sub-pixel of the current frame display image being 96, the determined OD factor is 100; and determining the OD factor to be increased currently according to the OD factors determined twice, wherein the OD factor is 96 according to the pixel value of the sub-pixel of the previous frame display image being 96 and the pixel value of the sub-pixel of the current frame display image being 96.
It should be noted that fig. 10 is merely an example, and the data set in the present application may be smaller than that shown in fig. 10.
