Description
Technical Field
The invention relates to the technical field of image processing, in particular to a method for removing moire fringes in an image detection process.
Background
In a display panel such as a liquid crystal panel or an organic EL panel, images and/or videos are displayed by different switching patterns of pixels (pixels) having R (red), G (green), and B (blue) sub-pixels, wherein three primary colors of R (red), G (green), and B (blue) constituting light are generally used, and a part of products are added with W (white) or Y (yellow) to obtain a wider color gamut or brightness expression. In general, in such a display panel, it is inevitable that there is a variation in processing accuracy in the manufacturing process, resulting in display unevenness.
The display unevenness is roughly classified into luminance unevenness and color unevenness. The uneven brightness causes brightness gradient between adjacent pixels; the relative luminance relationship of R, G, B (W, Y) where color unevenness occurs in each pixel has a gradient.
In particular, in the organic EL panel processing process, it is difficult to make the thickness of the organic compound layer uniform for each pixel, and therefore, the characteristic of regional display unevenness due to the non-uniform thickness of the organic compound layer is likely to occur.
As a countermeasure against this, patent document (CN105575326A) proposes a luminance measurement method of acquiring a luminance matrix of a display panel at least three gray levels; determining a brightness uniform area and a brightness non-uniform area according to the brightness matrix; measuring an actually measured Gamma curve of the brightness uniform region, and calculating a fitting Gamma value corresponding to each pixel point in the brightness non-uniform region at least three gray scales according to the brightness matrix; respectively fitting according to the actually measured Gamma curve and the fitted Gamma value to obtain a fitted Gamma curve of each pixel point in the area with uneven brightness; and performing brightness calibration on the area with uneven brightness according to the fitted Gamma curve of each pixel point. Through the mode, the invention can improve the precision of calibrating the uneven brightness and improve the calibration efficiency.
Patent literature (WO2013159377 a1) proposes another detection method, which obtains spatial illuminance values generated at a plurality of positions of a detection machine when a backlight module arranged on the detection machine is in a standard luminance, and takes the spatial illuminance values as standard spatial illuminance values (S201); acquiring real-time spatial illuminance values generated by the backlight module at the plurality of positions (S202); comparing the real-time spatial illumination value with the standard spatial illumination value to determine whether the backlight module is abnormal (S203). The detection method adopts the illuminance measuring instrument to replace a brightness measuring instrument, so that the cost is saved.
However, in all of the above methods, it is necessary to use a solid-state imaging device (CCD or CMOS) camera having a periodic arrangement to capture an image of a display panel having pixels arranged periodically, and in this case, the period of the camera pixel arrangement and the period of the display panel arrangement cannot be matched with each other, and thus, the captured images interfere with each other, and such interference fringes are referred to as Moire (Moire) in the art.
If the luminance of a pixel is measured based on a captured image in which moire has occurred, the luminance may not be measured correctly because the luminance of a pixel located at a position corresponding to moire on a display panel is measured to be too dark, and the like.
To cope with this, patent document (CN106664359A) discloses a method of capturing an image in a state where moire (M) generated at the time of focusing and capturing is generated, removing a spatial frequency component corresponding to the moire (M) from the captured image with a high-pass filter (12) to generate a1 st image, capturing the image out of focus with a camera (2), applying a low-pass filter (13) to the captured image to generate a2 nd image, and combining the 1 st image and the 2 nd image to generate a3 rd image in which the moire (M) is eliminated or suppressed. However, the method of removing moire in patent document 2 is complicated in operation and requires a special machine table.
