Description

Image display system and image display method
Technical Field
The present invention relates to the field of image display technologies, and in particular, to an image display system and an image display method.
Background
In a conventional flat panel display device, a structure of a display panel generally includes a plurality of pixels, each of which generally includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, i.e., each of which includes red, green and blue (RGB) sub-pixels. Each pixel realizes the gray scale adjustment of the pixel as a whole through the color adjustment of the red, green and blue sub-pixels, thereby realizing the display of a color image.
Accordingly, the image data inputted in the conventional display device is usually a plurality of RGB format data (i.e., RGB data … …, i.e., R sub-pixel gray scale, G sub-pixel gray scale, B sub-pixel gray scale … …), i.e., each pixel is provided with R sub-pixel gray scale, G sub-pixel gray scale, and B sub-pixel gray scale. However, as the structure of the display panel is more and more diversified, many display panels in the prior art do not include sub-pixels of three primary colors of red, green and blue for each pixel. For example, in a relatively large number of display panels, the sub-pixel structure is in RGBG form, and in this sub-pixel structure, two adjacent pixels each include a complete G sub-pixel, and both R and B sub-pixels are shared. In this case, if the image data input by the display device is still a plurality of RGB format data, there is a problem that the display cannot be performed or display is erroneous.
Therefore, how to reliably display an image in the case where there is a mismatch between the display panel structure and the input image data becomes a problem to be solved by those skilled in the art.

Detailed Description
The image display system and the image display method according to the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
[ EXAMPLES one ]
Please refer to fig. 1, which is a flowchart illustrating an image display method according to a first embodiment of the present invention. As shown in fig. 1, the image display method includes:
step S10: acquiring original image data, wherein the original image data comprises a plurality of original RGB form data (namely original RGB data, original RGB data and original RGB data … …, namely original R sub-pixel gray scale, original G sub-pixel gray scale, original B sub-pixel gray scale, original R sub-pixel gray scale, original G sub-pixel gray scale and original B sub-pixel gray scale … …), and the original RGB form data comprises original odd RGB form data displayed corresponding to odd columns and original even RGB form data displayed corresponding to even columns;
step S11: removing the R sub-pixel gray scale and the B sub-pixel gray scale in the original even RGB form data;
step S12: and converting the R sub-pixel gray scale and the B sub-pixel gray scale in the original odd RGB form data to obtain corresponding converted RGB form data, wherein the R sub-pixel gray scale and the B sub-pixel gray scale in the converted RGB form data can be shared by two pixels, namely the odd pixel corresponding to the (original odd RGB form data) and the even pixel adjacent to the odd pixel.
The converted RGB form data and the G sub-pixel gray scale left in the original even RGB form data form new image data together, and the new image data is RGBG form data
Here, the RGBG-form data may be formed by removing the R sub-pixel gray scale and the B sub-pixel gray scale in the original even RGB-form data among the received RGB-form data and transforming the R sub-pixel gray scale and the B sub-pixel gray scale in the original odd RGB-form data, so that the structure of the display panel may be matched with the input image data, thereby enabling the display panel to reliably display an image.
In this embodiment of the present application, converting R sub-pixel gray scale and B sub-pixel gray scale in original odd RGB format data to obtain corresponding converted RGB format data, where the R sub-pixel gray scale and B sub-pixel gray scale in the converted RGB format data can be shared by two pixels, namely an odd pixel and an even pixel adjacent to the odd pixel, of the corresponding odd pixel, and the two pixels include: converting R sub-pixel gray scale in original odd RGB form data to enable the R sub-pixel gray scale in the converted RGB form data to be shared by two pixels, namely corresponding odd pixels and even pixels in front of the odd pixels; and transforming the gray scale of the B sub-pixel in the original odd RGB form data, so that the gray scale of the B sub-pixel in the transformed RGB form data can be shared by the corresponding odd pixel and two pixels of the even pixel behind the odd pixel.
Here, in a display panel in which the sub-pixel structure is in an RGBG format, two adjacent pixels each include a complete G sub-pixel, and both R and B sub-pixels are shared, and in particular, the B sub-pixel of the k-th pixel is shared with the (k +1) -th pixel, the R sub-pixel of the (k + 2) -th pixel is shared with the (k +1) -th pixel, and k is an odd number; accordingly, when the R sub-pixel gray scale and the B sub-pixel gray scale in the original odd RGB format data are transformed, the R sub-pixel gray scale in the transformed RGB format data can be shared by the corresponding odd pixel and two pixels of the even pixel before the odd pixel, and the B sub-pixel gray scale in the transformed RGB format data can be shared by the corresponding odd pixel and two pixels of the even pixel after the odd pixel.
Further, the gray scale of the R sub-pixel in the original odd RGB form data is transformed according to the gray scale of the R sub-pixel in the original odd RGB form data and the gray scale of the R sub-pixel in the original even RGB form data before the original odd RGB form data. That is, the R-sub-pixel gray scale in the RGB format data after conversion takes into account the R-sub-pixel gray scale in the original odd RGB format data before conversion and the R-sub-pixel gray scale in the original even RGB format data before the original odd RGB format data before conversion, and thus the R-sub-pixel gray scale in the RGB format data after conversion takes into account the display effect of two pixels sharing the R-sub-pixel gray scale in the RGB format data after conversion.
Correspondingly, the gray scale of the B sub-pixel in the original odd RGB form data is converted according to the gray scale of the B sub-pixel in the original odd RGB form data and the gray scale of the B sub-pixel in the original even RGB form data after the original odd RGB form data. That is, the B-sub-pixel gray scale in the RGB format data after the conversion takes into account the B-sub-pixel gray scale in the original odd RGB format data before the conversion and the B-sub-pixel gray scale in the original even RGB format data after the original odd RGB format data before the conversion, and thus the B-sub-pixel gray scale in the RGB format data after the conversion takes into account the display effect of two pixels sharing the B-sub-pixel gray scale in the RGB format data after the conversion.
In one embodiment of the present application, the R sub-pixel gray scale in the original odd RGB format data is transformed specifically using:
if the difference value between the R sub-pixel gray scale in the original odd RGB form data and the R sub-pixel gray scale in the original even RGB form data in front of the original odd RGB form data is less than a first parameter, the R sub-pixel gray scale in the original odd RGB form data is transformed into: an average value of R sub-pixel gray levels in the original odd RGB pattern data and R sub-pixel gray levels in the original even RGB pattern data preceding the original odd RGB pattern data.
Specifically, the method can be expressed by the following formula:
if, | LuR (i) -LuR (i-1) | < beta 1;
then, lur (i)' (lur (i) + LuR (i-1))/2.
Where, lur (i) represents the R sub-pixel gray scale in the original odd RGB format data, LuR (i-1) represents the R sub-pixel gray scale in the original even RGB format data preceding the original odd RGB format data, lur (i)' represents the R sub-pixel gray scale in the RGB format data after conversion, and beta1 represents the first parameter. The first parameter is an index for identifying dispersion, and is preferably a standard deviation of gray levels of all R sub-pixels in the original image data (multiple pieces of original RGB format data).
If the difference value between the gray scale of the R sub-pixel in the original odd RGB form data and the gray scale of the R sub-pixel in the original even RGB form data before the original odd RGB form data is larger than a first parameter, and the gray scale of the R sub-pixel in the original odd RGB form data is smaller than the difference value between the gray scale of the R sub-pixel in the original odd RGB form data and the gray scale of the R sub-pixel in the original even RGB form data before the original odd RGB form data, transforming the gray scale of the R sub-pixel in the original odd RGB form data into: the product of the R sub-pixel gray scale in the original odd RGB form data, the ratio of the minimum value to the maximum value of the R sub-pixel gray scale in the original odd RGB form data and the R sub-pixel gray scale in the original even RGB form data before the original odd RGB form data, and a first coefficient.
Specifically, the method can be expressed by the following formula:
if, | LuR (i) -LuR (i-1) | > beta1& LuR (i) < | LuR (i) -LuR (i-1) |;
