Therefore, according to the scheme, the display can be ensured to accord with medical digital imaging and communication standards, and the display effect of the abnormal display area on the display can be eliminated.
The display correction method provided by the embodiment of the application will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a display correction method, including steps S101 to S105, wherein:
s101, determining a correction level for correcting the display brightness of an abnormal display area based on the display difference information of the abnormal display area and a normal display area in the target display when the target display displays a solid-color picture;
among them, the target display may be a display device such as an LCD (Liquid Crystal Display, liquid crystal display device), an OLED (Organic Light Emitting Display, organic light emitting diode display device), or the like. In one implementation, the target display may be a medical display.
The solid-color screen may be a screen when the display displays a gray-scale image corresponding to any gray-scale level, or the solid-color screen may be a single-color screen, for example, a solid-red screen, a solid-green screen, or a solid-blue screen, which may be all of them.
When the display is normal and no abnormal display area exists, the brightness information of pixels at each position of the display should be the same when the display is displaying a pure-color picture. In the case where the display has an abnormal display area, for example, a dead pixel area, the brightness information displayed by each pixel in the abnormal display area is different from the brightness information displayed by each pixel in the normal display area, for example, too bright or too dark, and at this time, in order to eliminate the influence of the abnormal display area on the display effect of the display, the correction level for correcting the display brightness of the abnormal display area may be determined based on the display difference information between the abnormal display area and the normal display area in the target display when the target display displays the solid-color picture.
Alternatively, the display difference information of the abnormal display area and the normal display area may be difference information of color temperature and/or brightness information, and further may be adjusted by correction data such as color temperature and brightness, and the abnormal display correction level of the target display may be determined by the light filling gain. Wherein, the determined abnormal display correction level can eliminate the influence of the abnormal display area on the display effect of the target display. Alternatively, the display difference information between the abnormal display area and the normal display area may be a difference between the luminance information of the abnormal display area and the luminance information of the normal display area. The luminance information of the abnormal display area may be luminance information displayed by any one of the pixels in the abnormal display, or the luminance information of the abnormal display area may be an average value of luminance information displayed by the pixels in the abnormal display. Similarly, the luminance information of the normal display area may be the luminance information displayed by any one of the pixels in the normal display, or the luminance information of the normal display area may be the average value of the luminance information displayed by the pixels in the normal display. The luminance information may be a luminance value or information representing a luminance value, as is all right.
The correction level for correcting the display luminance of the abnormal display area is used for correcting the digital excitation level of each pixel in the abnormal display area so that the display luminance of each pixel in the abnormal display area is the same as the display luminance of each pixel in the normal display area. The abnormal display area is an area on the target display in which an abnormality is displayed, and the normal display area is a display area on the target display other than the abnormal display area. Exemplary embodiments. As shown in fig. 2, an embodiment of the present application provides a schematic diagram of a target display, in fig. 2, a hatched area is an abnormal display area in the target display, and an area other than the hatched area in fig. 2 is a normal display area.
In one implementation manner, in order to determine a correction level for correcting the abnormal display area, image data when the target display displays a solid-color picture may be acquired in advance, and then, after acquiring the image data when the target display displays the solid-color picture, the abnormal display area of brightness in the target display may be determined as the abnormal display area based on the image data when the target display displays the solid-color picture.
The image data of the target display when displaying the solid-color image may be an image acquired by capturing the target display with an external camera, or may also be a screenshot of a display window obtained by performing a screenshot operation on the target display.
In one implementation, an area where a pixel in the target display whose pixel value does not match a specified pixel value is located may be determined as an abnormal display area based on image data when the target display displays a solid-color screen. The specified pixel value is a pixel value of theoretical display corresponding to the solid-color picture. For example, if the solid-color image is a gray-scale image corresponding to a gray-scale level of 100, the pixel value of the theoretical display corresponding to the solid-color image is gray-scale level of 100; for another example, if the solid-color picture is a solid-red picture, the pixel value of the theoretical display corresponding to the solid-color picture is R:255G:0B:0. If the image data includes pixels whose pixel values do not match the specified pixel values, it may be determined that there is an abnormality in the display of the pixels, so that an area in the target display where the pixels whose pixel values do not match the specified pixel values may be used as an abnormal display area. It is emphasized that it is possible that the above mentioned matching between the pixel values refers to the same between the pixel values or that the difference between the pixel values is smaller than a specified threshold.
Optionally, in one implementation manner, in order to improve efficiency of determining the abnormal display area, binarization processing may be performed on the image data when the target display displays the solid-color image, so as to obtain binarized image data, and further, connected domain identification is performed on the binarized image data, so as to determine each connected domain in the binarized image data, and an area corresponding to each connected domain in the target display is determined as a display area with abnormal brightness in the target display.
Optionally, after the connected domain identification is performed on the binarized image data, the position information of each connected domain in the binarized image data may be determined as the abnormal region position information, and then the region indicated by each abnormal region position information in the target display is determined as the display region with abnormal brightness in the image data. The position information of the connected domain may be the pixel coordinates of each power failure of the identification frame where the connected domain is located, or the center point coordinates of the identification frame. Alternatively, the position information of the connected domain may be a set of pixel coordinates of each pixel in the connected domain, or a pixel coordinate of a pixel at a geometric center point of the connected domain. This is all that is possible.
In one implementation manner, the image data may be imported into an OpenCV (open computer vision) library function, binarized to obtain binarized image data, and the number of connected domains (i.e., the number of bright points and/or the number of dark points) in the binarized image data is calculated, and then compared after the outer contour calculation, so as to determine the connected domains as an abnormal display area of the target display. Optionally, under the condition that an abnormal display area exists, the pixel centroid coordinates of the abnormal display area can be calculated through a centroid coordinate formula, and the position information of each connected area is calculated by combining the physical width and height of the display and the actual resolution. And further determining the area indicated by the position information of each abnormal area in the image data as the display area with abnormal brightness in the target display.
S102, when a target display is utilized to sequentially display a plurality of gray-scale images, the actual brightness information and the digital excitation level corresponding to each gray-scale image are utilized to construct a corresponding relation curve between the brightness information and the digital excitation level, and the corresponding relation curve is used as a first display characteristic curve;
the target display may be controlled to sequentially display a plurality of gray-scale images before executing the step, where the gray-scale image is an image when each pixel image in the target display displays the same gray-scale, and for example, gray-scale images with gray scales of 10, 50, 100, 150, 200, and 256 may be sequentially displayed. Where gray scale is the value of the digital actuation level of a display control pixel, generally speaking, the greater the gray scale of a pixel, which means the greater the digital actuation level required by the pixel. When the gray level to be displayed by a certain pixel in the target display is 10, the target display needs that the digital excitation level of the pixel is the digital excitation level corresponding to the gray level 10. In short, the gray scale can be understood as luminance information which is theoretically required to be displayed by the target display and is regulated by the digital excitation level, and the actual luminance information is the luminance information which is actually displayed when the target display displays according to the luminance information which is theoretically required to be displayed, for example, the luminance is often different from the actual luminance information, for example, the luminance is larger or smaller, and the display characteristic curve needs to be corrected.
In order to adjust the display characteristic curve of the target display, the display characteristic curve currently utilized by the target display needs to be determined first, optionally, the target display can be controlled to sequentially display a plurality of gray-scale images, and when the target display is further utilized to sequentially display the plurality of gray-scale images, the corresponding actual brightness information and digital excitation level of each gray-scale image are used to construct a corresponding relation curve between the brightness information and the digital excitation level, and the corresponding relation curve is used as a first display characteristic curve, and the first display characteristic curve can be understood as the display characteristic curve currently utilized by the target display, which possibly does not accord with the medical digital imaging and communication standards due to the influence of various factors, so that the correction is needed.
In one implementation manner, when a target display sequentially displays a plurality of gray-scale images, an actual brightness information corresponding to each gray-scale image can be obtained through a brightness meter, and when the target display sequentially displays the plurality of gray-scale images, a digital excitation level corresponding to each gray-scale image can be determined through a mode of reading the target display, so that a first display characteristic curve of the target display is constructed based on the actual brightness information corresponding to each gray-scale image and the digital excitation level.
The brightness meter is an optical collection device, such as CS150 and CA410, and can collect color data such as color coordinates, brightness, color temperature, tristimulus values, etc., and brightness information collected by the brightness meter is more accurate than brightness information determined based on image data.
S103, correcting the characteristic curve of the first display based on a standard DICOM curve to obtain a characteristic curve of the second display;
after determining the first display characteristic, the first display characteristic may be corrected based on the standard DICOM curve.
Optionally, for each standard luminance information in the standard DICOM curve, determining actual luminance information matched with the standard luminance information from the actual luminance information corresponding to each gray-scale image, as target luminance information, further determining a digital excitation level corresponding to the target luminance information based on the first display characteristic curve, as a digital excitation level corresponding to the standard luminance information, and constructing a corresponding relation curve between the luminance information and the digital excitation level based on each standard luminance information in the standard DICOM curve and the determined digital excitation level corresponding to each standard luminance information, as the second display characteristic curve.
The standard DICOM curve is a correspondence between standard luminance information and gray scale (which can also be understood as a digital excitation level) conforming to the digital imaging and communication standards of medicine. The standard brightness information is the brightness information required to be displayed by the medical display according to the DICOM standard.
For example, the standard DICOM curve includes standard luminance information including: standard luminance information a1, standard luminance information a2, standard luminance information a3; the actual luminance information corresponding to each gray-scale image includes luminance information b1, luminance information b2, luminance information b3 and luminance information b4, and in the first display characteristic curve, luminance information b1 corresponds to digital excitation level c1, luminance information b2 corresponds to digital excitation level c2, luminance information b3 corresponds to digital excitation level c3, and luminance information b4 corresponds to digital excitation level c4. The actual luminance information matching the standard luminance information a1 is determined from the luminance information b1, the luminance information b2, the luminance information b3, and the luminance information b4, for example, the luminance information b1 is determined as the target luminance information, and the digital excitation level corresponding to the luminance information b1 in the first display characteristic curve is the digital excitation level c1, and the digital excitation level c1 is the digital excitation level corresponding to the luminance information b 1. The standard luminance information a2 and the standard luminance information a3 are similar to the standard luminance information a1, and will not be described again.
Alternatively, the actual luminance information that matches the standard luminance information may be the same actual luminance information as the standard luminance information. Alternatively, the actual luminance information matching the standard luminance information may be actual luminance information satisfying a predetermined luminance difference condition with respect to the luminance difference information between the standard luminance information, and the luminance difference information may be information indicating a difference value of the luminance information. The specified difference condition may include that the luminance difference information between the specified luminance information and the standard luminance information is minimum; and/or the brightness difference information between the standard brightness information and the standard brightness information is smaller than a specified difference information threshold. The above specified difference information threshold may be determined on demand.
And S104, correcting the digital excitation level corresponding to each piece of brightness information in the second display characteristic curve based on the correction level to obtain a third display characteristic curve.
Since the display brightness of each pixel in the abnormal display area is different from the display brightness of each pixel in the normal display area, the second display characteristic curve cannot be directly used as the display characteristic curve of each pixel in the abnormal display area in the target display, and in order to further eliminate the influence of the abnormal display area on the display effect of the display, after the second display characteristic curve is obtained, the digital excitation level corresponding to each brightness information in the second display characteristic curve can be corrected based on the correction level to obtain the third display characteristic curve.
In one implementation manner, for each luminance information in the second display characteristic curve, the correction level may be used to adjust the digital excitation level corresponding to the luminance information in the second display characteristic curve to obtain an adjusted digital excitation level corresponding to the luminance information, and then based on each luminance information in the second display characteristic curve and the adjusted digital excitation level corresponding to each luminance information, a corresponding relation curve between the luminance information and the digital excitation level is constructed as the third display characteristic curve.

In the second display characteristic curve, the luminance information a1 corresponds to the digital driving level c1, and the correction level is k, and in the third display characteristic curve, the digital driving level corresponding to the luminance information a1 is the digital driving level c1+k. Optionally, when the abnormal display area is brighter, the correction level is negative, so as to reduce brightness information of the abnormal display area, and when the abnormal display area is darker, the correction level is positive, so that brightness information of the abnormal display area is improved, and influence of the abnormal display area on display effect of the display is eliminated.

In the scheme provided by the embodiment, after the first display characteristic curve is corrected based on the standard DICOM curve to obtain the second display characteristic curve, the digital excitation level corresponding to each piece of brightness information in the second display characteristic curve is corrected according to the correction level of the abnormal display area to obtain the third display characteristic curve, so that each pixel in the normal display area in the target display is corrected by using the second display characteristic curve, and each pixel in the abnormal display area in the target display is corrected by using the third display characteristic curve, and both the normal display area and the abnormal display area of the display can be ensured to meet the medical digital imaging and communication standards. Further, by correcting the correction level, when the third display characteristic curve is used for correcting each pixel in the abnormal display area in the target display, the display of each pixel in the abnormal display area can be corrected, so that the influence of the abnormal display area on the display effect of the display is eliminated. Therefore, according to the scheme, the display can be ensured to accord with medical digital imaging and communication standards, and the display effect of the abnormal display area on the display can be eliminated.
