Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
An embodiment of the present invention provides an image processing method, as shown in fig. 1, the method includes:
An image is a picture with visual effect, and in some computer image formats, an image may be composed of multiple image layers superimposed. An image layer is also understood to mean an image, for example, when an image is composed of 1 image layer, the image and the image layer may be identical.
The first color and the second color may include colors that can be recognized or set by a display device (e.g., a display screen of a mobile phone, a display screen of a smart mobile device, an LED electronic display device, etc.).
The target to be displayed may refer to a content that may be highlighted at a preset position on the currently displayed background image, including, but not limited to: characters, symbols, patterns, icons, or any combination of the above elements. The background image displayed at the present time may refer to a desktop background image currently displayed on a display device (not shown in the drawings), an incoming call interface background image, or other operation interface background images, and may also be an interface image of an application program, or the like.
In one embodiment, generating the first image is: generating a layer comprising the target with a first color according to a preset position of the target to be displayed on the background image; generating the second image is: and generating a layer comprising the target with a second color according to the preset position of the target to be displayed on the background image. Therefore, the position of the object in the first layer is the same as the position of the object in the second layer, but the color is different. Furthermore, in the first layer, the pixels are transparent, i.e. without content, except for said object having the first color. Also in the second layer, the pixels are transparent, i.e. without content, except for said object having the second color.
The first color and the second color may be opposite colors, and taking Red Green Blue (RGB) color mode as an example, the result of adding the RGB color of the first color and the RGB color of the second color is white (255, 255, 255). In practical applications, common combinations of opposite colors may be selected as the first color and the second color, for example: if the first color is white (255, 255, 255), the second color is black (0, 0, 0); if the first color is red (255, 0, 0), the second color is (0, 255, 255); if the first color is magenta (255, 0, 255), the second color is green (0, 255, 0).
And 12, combining the first image and the currently displayed background image to generate a third image, wherein in the third image, the target with the first color is reserved at least in an area with a color difference with the background image being above a preset threshold value.
And in the third image, the region except the region of the target with the first color and the background image with the color difference above a preset threshold value is completely and transparently displayed or has no other display content.
The image display effect is realized in such a way that image elements of the background image appear in a region outside the target, the target displays a first color in a region with the color difference between the first color and the background image being above a preset threshold, and the rest regions of the target display a second color.
In some embodiments, the first color may be black and the second color may be white.
In some embodiments, the target may be text.
The color difference may include a numerical difference between pixel points of the picture in a color mode, and common color modes include: RGB mode, print Color (CMYK) mode, color model (Lab) mode, and the like. Taking the RGB mode as an example, the color difference between the pixels can be obtained by comparing the values of the pixels in the three R/G/B color channels, the luminance of the pixels can be calculated by a general luminance calculation formula, and the direct color difference of the pixels can be obtained by comparing the luminance of the pixels.
In one embodiment, the step 12 includes:
carrying out binarization processing on the background image to obtain a fifth image;
and combining the first image and the fifth image to generate the third image, wherein the target with the first color is reserved at least in an area with the color difference with the fifth image being above a preset threshold value.
In some embodiments, combining the first image and the fifth image to generate the third image comprises: and performing masking processing on the first image by using the fifth image to generate the third image.
In some embodiments, when the background image is binarized, parameters such as a binarization radius and the like may be optimized, including: setting a binarization radius according to the width of a line (such as a character stroke) of a target; the minimum/maximum binarization radius is set according to the maximum/minimum width of the target line (e.g., character stroke). The binarization radius refers to that when the binarization processing process is executed, image optimization processing can be further performed, and the image optimization processing comprises the following steps: and (5) image denoising processing. For example, to avoid the extreme drastic black-white change of the image pixel points, the noise points with radius/width smaller than n pixels after binarization are filtered by means of mean filtering, median filtering, gaussian filtering and the like, that is, the noise points are filtered in the region with drastic color change to remove the noise points; the area with violent light and shade change can be reduced, the color transition of the target is more natural, and the visual effect is better.
In one embodiment, the step 12 includes:
carrying out gray level transformation on the background image to obtain a sixth image;
the gray scale transformation is to convert a color image into a gray scale image. The gray scale transformation methods that can be selected are the weighting method, the averaging method, and the maximum method. Taking the RGB color mode as an example: the weighting method is to calculate the weighted arithmetic mean of the RGB values of each pixel point of the image to obtain the GRAY value, and the general formula can be expressed as GRAY ═ 0.3 × R +0.59 × G +0.11 × B; the average method is to calculate the arithmetic mean of the RGB values of each pixel point of the image to obtain the GRAY value, and the formula can be represented as (R + G + B)/3 ═ GRAY; the maximum value method is to select the maximum value of the RGB values of the pixel points as the gray value, and the formula can be expressed as max (R, G, B).
Determining transparency values of at least part of pixels according to the gray values of at least part of pixels in the sixth image;
and generating the third image by combining the first image and the gray value, wherein the target with the first color is reserved at least in an area with the color difference with the sixth image being above a preset threshold value.
The preset threshold value, for example, the RGB color mode, may be 255. For example, when the grayscale value of the sixth image is 255, the region of the object having the first color whose grayscale value is 0 remains; or, when the grayscale value of the sixth image is 0, the region of the object having the first color with the grayscale value of 255 remains.
In some embodiments, the determining the transparency value of at least some pixels in the sixth image according to the gray scale value of the at least some pixels further includes:
and determining a transparency value of a target pixel according to a gray value of the target pixel in the sixth image, wherein the target pixel is a pixel of which the color difference between the gray value and the target with the first color is below the preset threshold.
And the transparency value is used for representing the transparency of the target pixel. Taking the RGB color scheme as an example, the transparency value can be divided into 256 levels, i.e. 0-255, where 0 is transparent and 255 is opaque. And the range of gray values can also be represented as 0-255, where black is 0 and white is 255. Therefore, as the gray value of the target pixel in the sixth image is closer to white, the transparency of the target pixel is closer to opaque.
In some embodiments, said combining said first image and said transparency values to generate said third image comprises:
introducing the transparency values into the first image, generating the third image.
The introducing of the transparency value into the first image means determining the transparency of the first image according to the transparency, for example, substituting the transparency value into an Alpha channel of the first image. Such that the closer the first color of the area of the first image having the first color is to white in the background image, the closer the first color is to opaque, the closer the first color of the area of the first image having the first color is to black in the background image, the closer the first color is to transparent.

Then, the processed black text layer is superimposed and displayed on the background image and the white text layer, that is, the result shown in fig. 9 is obtained, and the black and white change of the text is not abrupt change but continuous gradual change.
In one embodiment, when performing the gradation processing on the background image, the contrast adjustment is performed on the region of the intermediate luminance, the gray region having a luminance close to white is adjusted to white, the region having a luminance close to black is adjusted to black, and the gray region having a middle luminance is adjusted to gray. For example: the gray scale values are 0 to 255, the area with the luminance of 170 or more is adjusted to white, the area with the luminance of 85 or less is adjusted to black, and the other area is adjusted to gray of the gray scale 127 (for only one reference, the parameter may be adjusted according to the luminance change degree of the background picture).
