Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising" does not exclude the presence of additional identical elements in a process, method, article, or apparatus that comprises the element.
Example 1
The embodiment of the invention provides an OSD interface color self-adaptive adjustment method, which is suitable for equipment such as televisions, conference sets, projection equipment, display screens and the like, and the equipment displays video signals, picture signals and the like input into the equipment through a (man-machine) interaction interface.
Referring to fig. 1, the method for adaptively adjusting the OSD interface color specifically includes the following steps:
s1, responding to an OSD interface display instruction, acquiring an area for displaying the OSD interface in the interactive interface, and marking the area as an OSD interface display area;
S2, acquiring a color value of a picture in the OSD interface display area, and marking the color value as a first picture background color value;
S3, adjusting the color of the OSD interface according to the background color value of the first picture;
And S4, displaying the OSD interface after color adjustment in the OSD interface display area and placing the OSD interface in the upper layer of the picture.
Specifically, the OSD interface is generally used for displaying state information, setting options and other related information of the device, when the information needs to be acquired, an OSD interface display instruction is often sent to the device through a remote controller or a touch key in an interactive interface, when the device receives the OSD interface display instruction, a specific area where the OSD interface is to be displayed in the interactive interface is first determined and recorded as an OSD interface display area, a color value of a current picture in the OSD interface display area is acquired, an OSD interface color is set based on the color value of a picture background in the OSD interface display area, so that the OSD interface forms a sufficient contrast with a background picture color of a next layer thereof, the adjusted OSD interface is displayed in the OSD interface display area, and the adjusted OSD interface is ensured to be positioned on an upper layer of the current picture, so that a user can clearly see interface content when operating the OSD interface without interference of the background picture.
In one embodiment, before adjusting the color of the OSD interface according to the first picture background color, the method further includes:
s0, setting the transparency of the OSD interface according to a preset transparency value.
Specifically, in order to further improve the visual effect and adaptability of the OSD interface, the transparency of the OSD interface is first adjusted according to a preset transparency value before the color of the OSD interface is adjusted according to the background color of the first picture. The transparency is set to make the OSD interface not only have enough contrast to ensure visibility, but also to integrate with the background picture, thereby reducing interference to the overall visual effect. By setting a proper transparency value, the OSD interface can avoid being too abrupt on the premise of ensuring clear identification of the user, and the visual experience and operation feeling of the user are improved. The preset transparency value can be determined according to user preference or actual application scene, and the operating system of the device adjusts the transparency of the OSD interface according to the preset transparency value to achieve the required transparency effect.
Referring to fig. 2, in one embodiment, the method further comprises:
s5, after a preset time interval, acquiring a color value of a picture in the OSD interface display area, and marking the color value as a second picture background color value;
s6, judging whether the difference value between the second picture background color value and the first picture background color value is larger than or equal to a preset threshold value;
s7, if not, executing the step S5, and if yes, executing the step S8:
And S8, setting the first picture background color value to be equal to the second picture background color value, executing the steps S3 to S4, and then jumping to the step S5.
Specifically, when the OSD interface is displayed for a long time, or when the OSD interface (such as a side bar of a conference machine or an OSD interface such as an electronic compass) is required to be suspended on the upper layer of the picture in the process of playing the picture, the color value of the picture in the OSD interface display area is obtained again at a preset time interval (for example, every second or every 5 seconds) in the process of displaying the OSD interface, and the new color value is recorded as the second picture background color value. Judging whether the difference value of the second picture background color value and the first picture background color value is larger than or equal to a preset threshold value, if the difference value is smaller than the preset threshold value, indicating that the color change of the background picture is not obvious, the OSD interface color does not need to be readjusted, if the difference value is larger, meaning that the color of the background picture is obviously changed, setting the first picture background color value to be equal to the second picture background color value at the moment, then adjusting the color value of the OSD interface according to the first picture background color value, refreshing the interactive interface, and refreshing the OSD interface to dynamically adjust the color of the OSD interface according to the picture color change.
Referring to fig. 3, in one embodiment, the obtaining the color value of the picture in the OSD interface display area, denoted as the first picture background color value, includes:
S21, obtaining RGB values of each pixel of a picture in the OSD interface display area;
s22, obtaining the first picture background color value according to the average value of the RGB values of each pixel.
Specifically, to accurately acquire the background color value of the first picture, the RGB value of each pixel of the current picture in the region is first acquired. Specifically, by scanning all pixels of the current picture in the OSD interface display area, the values of three color components of red (R), green (G), and blue (B) for each pixel are extracted. Then, the RGB values of these pixels are counted and calculated to obtain an average value of the RGB values of all the pixels. The average value represents the overall color characteristics of the picture in the display area of the OSD interface, and in this way, the color condition of the picture in the display area of the OSD interface can be accurately reflected, so that a reliable data base is provided for the subsequent adjustment of the color of the OSD interface.
In one embodiment, the weighted average calculation can be further performed on the RGB values of each pixel according to the importance of different positions in the OSD interface display area (for example, the weights of the user's line of sight concentrated area and the edge area are different), so as to more accurately reflect the color characteristics of the user's actual attention area to improve the accuracy of OSD interface color adjustment.
Referring to fig. 4, in an embodiment, the color distribution of the picture in the OSD interface display area may be further analyzed, and the primary color and secondary color of the background color are identified by counting the distribution and proportion of the primary color of the picture in the area, and the OSD interface color is adjusted by combining these information, so as to ensure that the OSD interface can maintain good contrast and visual effect under various background conditions. The method comprises the following specific steps:
s23, obtaining RGB values of all pixels of a picture in the OSD interface display area;
s24, carrying out quantization processing on RGB values of all pixels;
for example, 256 levels of RGB values may be compressed to 16 or 32 levels by dividing the continuous color values into discrete intervals, making color analysis more efficient;
s25, counting the quantized RGB values to generate a color histogram;
The color histogram represents the number of pixels of different colors (RGB values) in the OSD interface display area and the distribution condition thereof, and each color value corresponds to a count and represents the frequency of the color in the OSD interface display area;
s26, obtaining a color value with highest frequency according to the color histogram, marking the color value as a dominant hue color value, and marking a color value with frequency as a minor hue color value;
in other embodiments, the primary and secondary hues may also be distinguished by setting a preset threshold, such as a primary hue if the frequency of color occurrence exceeds the threshold.
S27, obtaining a weighted average color value according to the dominant hue color value and the minor hue color value, namely the first picture background color value:
and determining corresponding weighted values according to the frequency proportion of occurrence of the primary tone and the secondary tone so as to determine weighted average color values of the primary tone and the secondary tone, wherein the weighted average color values are the first picture background color values.
Referring to fig. 5, in one embodiment, the adjusting the color of the OSD interface according to the first picture background color value includes:
s31, acquiring an OSD interface color value according to the first picture background color value and a preset color correction value;
s32, setting the color of the OSD interface according to the color value of the OSD interface.
Specifically, the preset color correction value is used for ensuring that the color of the OSD interface and the background color form enough contrast, so that the OSD interface is more clearly visible when displayed. The calculation formula for calculating the OSD interface color value according to the first picture background color value and the preset color correction value is as follows:
OSD interface color value=first picture background color value±preset color correction value;
the preset color correction value can be adjusted according to actual conditions or user preferences and the like so as to adapt to different background pictures.
Further, one or more of color saturation, contrast, and brightness of the OSD interface is determined according to the illumination intensity of the current environment, and illustratively, when the illumination intensity is acquired to be 900lux, the color saturation is moderately increased (for example, 20% is increased), the color is made more vivid, the contrast is enhanced (for example, 30% is increased), the visibility in a high-light environment is ensured, the brightness is reduced (for example, 10% is reduced), and visual fatigue caused by excessive brightness is avoided. The adjusted color value and the attributes (saturation, contrast and brightness) of the OSD interface are applied to the OSD interface, so that the OSD interface is always clearly visible and has good visual effect under the current illumination condition.
In summary, the method for adaptively adjusting the color of the OSD interface according to the embodiment of the present invention includes obtaining an OSD interface display area in an interactive interface in response to an OSD interface display instruction, obtaining a color value of a picture in the OSD interface display area, and marking the color value as a first picture background color value, adjusting the color of the OSD interface according to the first picture background color value, displaying the color-adjusted OSD interface in the OSD interface display area, and placing the OSD interface in an upper layer of the picture. According to the method, the picture color value in the display area of the OSD interface is obtained to dynamically adjust the color of the OSD interface, so that the color of the OSD interface can be distinguished from the background picture color and can be adapted to the background picture color, the problem of visibility of the OSD interface is solved, the defect of attractive appearance caused by using an OSD interface which is not transparent and has special color is avoided, clear display and attractive appearance of the OSD interface under various background pictures are realized, and the use experience of a user is remarkably improved. Whether the user watches a film, displays the PPT or performs other operations, the OSD interface can automatically adapt to the background picture change, better visual effect is provided, and the accuracy and the overall experience of the user operation are improved.
