Embodiments of the present invention provide an information processing method and an electronic device, which are used to solve the technical problem in the prior art that a wallpaper as a background image is similar to an icon of an application program, and the wallpaper interferes with a user finding the icon of the application program.
In the embodiment of the invention, when a first background image is displayed on a display unit of an electronic device, a key image area and a non-key image area on the first background image are determined, then the key image area and the non-key image area are subjected to image processing to obtain a processed second background image, and finally the second background image is displayed on the display unit.
The method for displaying the wallpaper is characterized in that a key image area and a non-key image area of the wallpaper are processed, a processed background image is used as the wallpaper, the key image area of the wallpaper can be highlighted, and meanwhile interference of the wallpaper on an icon of an application program is reduced as much as possible.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The embodiment provides an information processing method, which is applied to an electronic device, wherein the electronic device is provided with a display unit. The electronic equipment can be a smart phone, a tablet computer, a notebook computer and the like, and the display unit can be a touch display screen, a liquid crystal display screen, an LED display screen and the like.
A first background image is displayed on a display unit of the electronic device. The first background image may be a wallpaper set by the electronic device from a factory or a wallpaper customized by a user of the first electronic device. Icons of application programs installed on the electronic device or icons of factory settings of the electronic device are also generally displayed on the wallpaper. If the wallpaper is similar to the icon of the application, the wallpaper may interfere with the user's finding the icon of the application. In order to reduce the interference of the wallpaper on the icon of the application program found by the user as much as possible, the embodiment of the invention provides a wallpaper display mode, wherein the key image area and the non-key image area of the wallpaper are determined, the key image area and the non-key image area are subjected to image processing, the processed background image is used as the wallpaper to be displayed on a display unit, and the interference of the wallpaper on the icon of the application program is reduced as much as possible while the key image area of the wallpaper is highlighted.
Referring to fig. 1, fig. 1 is a flowchart of an information processing method according to an embodiment of the present invention. The method comprises the following steps:
step 11: when a first background image is displayed on the display unit, determining an important image area and a non-important image area on the first background image;
step 12: performing image processing on the key image area and the non-key image area to obtain a processed second background image;
step 13: displaying the second background image on the display unit.
There are various methods for determining the emphasized image region and the non-emphasized image region of the first background image in step 11. One possible approach is face recognition. If the wallpaper is an image with people and scenery, the image area with people can be determined to be a key image area by face recognition, and the scenery is a non-key image area. Another possible method is image matching. The method comprises the steps that some images are customized as key images by the electronic equipment factory settings or the user of the electronic equipment, the wallpaper is matched with the key images, the area matched with the key images in the wallpaper is a key image area, and other areas of the wallpaper are non-key image areas. For example: the user of the electronic equipment defines the cat as a key image, if the wallpaper has the cat, the cat is used as a key image area, and other areas in the wallpaper are used as non-key image areas.
Still another possible method is to determine the emphasized image region and the non-emphasized image region of the first background image according to the user's operation with respect to the display unit. Assuming that the display unit is a touch display unit, a user performs a sliding operation on the touch display unit, and a sliding track is a circle, the background image inside the circle can be determined as a key image area, and the background image outside the circle is determined as a non-key image area; or if the sliding track is a line segment, the background image with a smaller area in the two image areas divided by the line segment is used as a key image area, and the background image with a larger area is used as a non-key image area. If the sliding track is a touch area formed by one touch point generated by a stylus on the touch display unit or a plurality of touch points generated by fingers on the touch display unit, and the key image area and the non-key image area cannot be determined according to the operation of the user, the following method may be adopted:
receiving a predetermined operation of a user for a first display area of the display unit;
determining a first image area corresponding to the first display area in the first background image;
and determining the key image area and the non-key image area according to the first image area.
Determining the key image area and the non-key image area according to the first image area, specifically:
obtaining basic characteristic values of basic pixel points in the first image area;
with the basic pixel point as the center, judging whether pixel points around the basic pixel point are matched with the basic characteristic value;
and collecting the pixel points matched with the basic characteristic values to form the key image area, and collecting the pixel points not matched with the basic characteristic values to form the non-key image area.
Specifically, a first background image is displayed on a display unit of the electronic device, a display area of the display unit is composed of a plurality of touch points, each touch point has unique coordinates, and each touch point corresponds to one pixel point of the first background image. When a user touches the touch unit by using the touch pen to generate a touch point, the electronic device can acquire the coordinates of the touch point, and then can determine the pixel point corresponding to the touch point. And taking the pixel points corresponding to the touch points as basic pixel points, and obtaining the gray value, the brightness value, the color value and the like of the basic pixel points. And then comparing the gray value, the brightness value, the color value and the like of the pixel points around the basic pixel points with the gray value, the brightness value, the color value and the like of the basic pixel points, and if the gray value, the brightness value, the color value and the like of the basic pixel points are similar to the gray value, the brightness value, the color value and the like of the basic pixel points, dividing the surrounding. That is to say, the pixel points corresponding to the touch points are used as seed regions, and the pixel expansion of the image is performed by using a region growing method, so that a complete connected domain can be formed, the expanded region is an important image region, and the other regions are non-important image regions. When a user touches the touch unit with a finger to generate a touch area, all the pixels in the touch area can be used as basic pixels, and the key image area can be determined according to the same method. Except the area of the image of the focus point, the first background image is the area of the non-focus image.
Therefore, in the embodiment of the present invention, the emphasized image region and the non-emphasized image region of the first background image are determined according to the operation of the user on the display unit, and the position of the operation of the user on the display unit is different, so that the determined emphasized image region and the determined non-emphasized image region are different.
In particular, the first background image may be a 3D image. Because the 3D image is obtained by shooting through the double cameras, the 3D image has a depth image, the larger the gray value in the depth image is, the closer the shot object is to the photographer, and the 3D image has a gray threshold value which can distinguish the foreground from the background.
In this embodiment of the present invention, after obtaining the basic feature value of the basic pixel point in the first image region, the method further includes:
judging whether a basic gray value in the basic characteristic values is larger than a preset gray value, wherein the preset gray value is used for distinguishing a foreground from a background of the first background image;
if the basic gray value is larger than the preset gray value, executing the following steps: and with the basic pixel point as the center, judging whether the pixel points around the basic pixel point are matched with the basic characteristic value.
Specifically, if the first background image is a 3D image, after obtaining the gray value, the luminance value, the color value, and the like of the basic pixel point, the gray value of the basic pixel point is first compared with a predetermined gray value, which is the gray value used for distinguishing the foreground and the background of the first background image in the 3D image, if the gray value of the basic pixel point is greater than the predetermined gray value, it is indicated that the image area corresponding to the display area touched by the user is the foreground of the first background image, and then the gray value, the luminance value, the color value, and the like of the pixel points around the basic pixel point are compared with the gray value, the luminance value, the color value, and the like of the basic pixel point, so as to determine the key image.
If the gray value of the basic pixel point is less than or equal to the preset gray value, it is indicated that the image area corresponding to the display area touched by the user is the background of the first background image, and the background of the first background image is divided into two parts: an image composed of pixels having a gray value smaller than that of the basic pixels is a first part, and an image composed of pixels having a gray value between that of the basic pixels and a predetermined gray value is a second part. Blurring the first part, and adding special effects such as light spots and snowing on the second part.
After step 11 is performed, step 12 may be performed, in which the highlight image area and the non-highlight image area are subjected to image processing to highlight the highlight image area of the first background image. There are various methods for performing image processing, and in the embodiment of the present application, there are, but not limited to, the following methods for performing image processing on an emphasized image region and a non-emphasized image region:
the first method comprises the following steps: taking the pixel points in the non-key image area as target pixel points, and determining the average value of the characteristic values of the pixel points around the target pixel points; and setting the average value as the fuzzy characteristic value of the target pixel point.
Specifically, in order to highlight the emphasized image region, image processing may be performed on the non-emphasized image region. Taking the pixel points in the non-key image area as target pixel points, averaging the gray value, the brightness value, the color value and the like of the pixel points around the target pixel points, and setting the average value as the gray value, the brightness value, the color value and the like of the target pixel points. Because the gray value, the brightness value, the color value and the like of the target pixel point are the average values of the gray value, the brightness value, the color value and the like of the surrounding pixel points, the gray value, the brightness value, the color value and the like of the pixel points in the non-key image area after the processing are similar, and a fuzzy effect is formed. Besides blurring the non-key image area, the non-key image area can be blurred, so that the interference of the processed non-key image area on the icon of the application program is greatly reduced.
For example: fig. 2 is a schematic diagram of a first background image according to an embodiment of the invention. Fig. 3 is a schematic diagram of an image obtained by image processing the non-emphasized image region in fig. 2. As can be seen from fig. 3, the emphasized image regions are highlighted, while the non-emphasized image regions are blurred.
In addition, in order to highlight the emphasized image region, the image processing may be performed on the emphasized image region simultaneously with or after the image processing is performed on the non-emphasized image region. And (3) carrying out general image processing methods such as sharpening, edge enhancement and the like on the key image area, and if the key image area is identified as a human face, carrying out special effects such as beautifying, face thinning, whitening and the like.
The second method comprises the following steps: taking the color value with the largest occurrence frequency in the color values of the pixel points in the first background image or the non-key image area as a key color value; and setting the color value of the pixel point in the non-key image area as a target color value, wherein the difference value between the target color value and the key color value is greater than a preset value.
Specifically, the times of occurrence of color values of pixel points on the first background image or the non-emphasized image area are counted, and the color value with the largest occurrence time is used as an emphasized color value. And then, changing the color value of the pixel point in the non-key image area into a target color value with the difference with the key color value larger than a preset value. That is to say, adopt and press black, color filter, select the colour opposite with key colour value as target colour value, the difference of target colour value and key colour value is bigger, and the effect of salient key image area is more obvious. For example: the emphasis color value is yellow, and the color value of the non-emphasis image area can be changed to gray or black.
In order to make the visual effect of the processed image natural and unobtrusive, in the embodiment of the present invention, a third method is further provided:
taking pixel points of an edge area between the key image area and the non-key image area as target edge pixel points; determining an average value of characteristic values of pixel points around the target edge pixel point; and setting the average value as the edge fuzzy characteristic value of the target edge pixel point.
Specifically, smoothing is performed on pixel points at the boundary between the highlight image area and the non-highlight image area. And taking the pixel points at the junction as target pixel points, then averaging the gray values, the brightness values, the color values and the like of the pixel points around the target pixel points, and setting the average value as the gray values, the brightness values, the color values and the like of the target pixel points. Because the gray value, the brightness value, the color value and the like of the target pixel point are the average values of the gray value, the brightness value, the color value and the like of the pixel point at the boundary of the key image area and the non-key image area around the target pixel point, the gray value, the brightness value, the color value and the like of the pixel point in the processed key image area and the non-key image area are similar to form a transition, and the boundary of the non-key image area and the key image area does not appear to be too sharp and unnatural any more.
After step 12 is performed, step 13 may be performed to display the processed image as a second background image on the display unit.
One possible application scenario is: when the display unit of the electronic device is in the screen locking state, the screen locking wallpaper on the display unit is the first background image, as shown in fig. 4. Then, the user performs an unlocking operation with respect to the display unit, and generates a touch area on the display unit, where the touch area corresponds to the image area of the person jacket in fig. 4. And taking the image area of the coat of the person as the center, and performing pixel expansion of the image by using a region growing method, so that a complete connected domain can be formed, wherein the expanded area is the person, the person is determined as an important image area, and the other areas are non-important image areas. And (3) performing line blurring, blackening, color filtering and other processing on the non-key image area, and performing smoothing processing on the edge of the key image area and the non-key image area to obtain a processed image as a second background image, as shown in fig. 5. And after the display unit of the electronic equipment is unlocked, taking the second background image as the unlocked desktop wallpaper. As can be seen from fig. 5, the key image area is highlighted in the second background image, reducing the interference of the background image to the application icon.
In the possible application scenes, when the display unit of the electronic equipment is in a locked state, the display unit displays a first background image as the screen locking wallpaper, when the electronic equipment is unlocked after receiving an unlocking operation of a user, the display unit displays a scene cut animation, the first background image is transited to a second background image, and the second background image is used as the desktop wallpaper after unlocking, so that the wallpaper display effect is excessively natural.
