Detailed Description
The technical solutions of the embodiments of the present invention are described in detail with reference to the drawings and the specific embodiments, and it should be understood that the specific features of the embodiments and the embodiments of the present invention are detailed descriptions of the technical solutions of the embodiments of the present invention, and are not limited to the technical solutions of the embodiments of the present invention, and the technical features of the embodiments and the embodiments of the present invention may be combined with each other without conflict.
In a first aspect, in order to solve the problem that when a display displays a certain still image for an excessively long time, pixels of a portion of the display displaying the still image are easily overheated, so that the pixels of the still image remain on the display, the present invention includes a method for processing an image of the display, as shown in fig. 1, the method comprising:
step 101 of controlling the display of a still image on the display.
Specifically, controlling the display of a still image on the display includes: step 201: and receiving the electric signal of the image and controlling the display to display the image.
More specifically, an electrical signal of the image is received, and the display is controlled to display the image. The display is provided with a signal receiving module and a signal conversion module, and can acquire an electrical signal of an image through the signal receiving module, and output the image after converting the electrical signal through the signal conversion module, so that the image is displayed on the display. Wherein, the display includes but is not limited to: cell-phone, panel computer, intelligent wrist-watch, virtual reality equipment, display device.
As shown in fig. 2, the controlling of displaying a still image on the display further includes: the state of the image displayed on the display is detected 202.
Specifically, detecting the state of an image displayed on a display may be achieved by two alternative implementations:
in a first alternative implementation, through step 301: calculating the time when the image is still at any position of the display;
step 302: judging whether the time for which the image is static at any position of the display is greater than or equal to a first preset time or not;
if the time for which the image is static at any position of the display is greater than or equal to a first preset time, determining that the image displayed on the display is in a static state;
and if the time for which the image is static at any position of the display is less than the first preset time, determining that the image displayed on the display is in a motion state.
In a second alternative implementation, as shown in fig. 3, through step 303: calculating the total number of the image frames displayed by the display in a second preset time;
step 304: judging whether the total frame number of the images displayed by the display in the second preset time is smaller than a first preset value or not;
if the total frame number of the images displayed by the display in the second preset time is smaller than the first preset value, determining that the images displayed on the display are in a static state;
and if the total frame number of the images displayed by the display in the second preset time is greater than or equal to the first preset value, determining that the images displayed on the display are in a motion state.
By the method, whether the image is static on the display can be judged, for example, within 1 second, the display should display 60 frames of images, and if the second preset time is also 1 second, and the display displays 5 frames of images within another 1 second, it indicates that the image displayed on the display is static within a certain time. If the display shows 60 frames of images in another 1 second, it may indicate that the images shown on the display are moving within that 1 second. Therefore, whether the image displayed on the display is static or moving can be judged by calculating the total frame number of the image displayed by the display in the second preset time.
When it is detected that the image displayed on the display is in a still state, it is possible to control the pixels of the image to move from the original pixel position to the target pixel position over at least two frames and adjust the pixel values of the pixels of the image at the target pixel position, via step 102.
Specifically, by the above method, the pixels of the image are controlled to move from the original pixel positions to the target pixel positions by at least two frames, thereby avoiding the pixels of the image from remaining at the original pixel positions when the pixels of the image are moved from the original pixel positions to the target pixel positions by one frame.
By the method, the pixel value of the pixel of the moved image at the target pixel position is adjusted, so that the display effect of the moved image is effectively improved, and the phenomenon that when the display displays a certain static image for more than a preset time, the pixel of the static image part displayed on the display is overheated, the pixel of the static image possibly remains on the static image part displayed on the display, and the pixel of the static image part displayed on the display is burnt out due to worse condition, so that the pixel of the static image part cannot be displayed is avoided.
In an alternative implementation manner, as shown in fig. 4, the method for processing an image of a display according to an embodiment of the present invention further includes:
step 401: the original pixel location information for the pixels of the image is identified from the pre-stored data center by a pixel location information matching algorithm.
Specifically, the original pixel location information for the pixels of the image includes identifying that the pixels of the image are specifically located at specific coordinates displayed by the display, such as at row i, column j.
Step 402: and according to the original pixel position information of the pixels of the image, acquiring a moving path bound by the pixels containing the image moving from the original pixel position to the target pixel position according to a preset pixel position matching algorithm.
If the moving path is one, the pixel of the image is controlled to move from the original pixel position to the target pixel position through at least two frames along the moving path according to step 403;
if the moving path is two or more, step 404, prompting the user to select one moving path from the moving paths, step 405, and adopting the moving path corresponding to the user selection result, then controlling the pixel of the image to move from the original pixel position to the target pixel position at least through two frames along the moving path.
Specifically, the movement path to which the pixel of the acquired image moves from the original pixel position to the target pixel position through the above method specifically includes, as shown in the figure, a movement path that can be selected when the pixel of the acquired image moves from the position of a specific coordinate a (i-th row, j-th column) of the display to the position of another specific coordinate B (i + 1-th row, j-1-th column) of the display, and the pixel of the control image can move from the original pixel position to the target pixel position through at least two frames along the above movement path by moving from a specific coordinate a point to a specific coordinate B point through a square as shown in (1) in fig. 6, (2) parallelogram in fig. 6, or (3) octagon in fig. 6.
In an alternative implementation manner, in step 403 or 404, the moving the pixel of the image from the original pixel position to the target pixel position through at least two frames along the moving path specifically includes:
step 501: identifying whether the pixels of the image are edge pixels from a pre-stored data center according to the original pixel position information of the pixels of the image and a pixel position information matching algorithm;
if the pixel of the image is an edge pixel, adjusting the pixel value of the pixel of the image at the target pixel position according to the preset edge pixel feathering algorithm in the step 502;
if the pixel of the image is a non-edge pixel, the non-edge pixel eclosion algorithm is preset according to step 503 to adjust the pixel value of the pixel of the image at the target pixel position.
It should be noted that, for example, if the display receives all the row electrical signals of the image in sequence, the position of the pixel of the image displayed after the first row electrical signal and the last row electrical signal are converted is the edge pixel position, then the display receives all the column electrical signals of the image in sequence, the position of the pixel of the image displayed after the first column electrical signal and the last column electrical signal are converted is the edge pixel position, the pixels of all the edge pixel positions are all indexed as edge pixels, the positions of the pixels of the image displayed after the other electrical signals are converted are non-edge pixel positions, and the pixels of all the non-edge pixel positions are indexed as non-edge pixels. Therefore, when the location information of the pixels of the image is recognized from the pre-stored data center according to the pixel location information matching algorithm, it can be recognized whether the pixels of the pixel location of the image are edge pixels.
In an alternative implementation manner, if the pixel of the image is an edge pixel, the pixel value of the pixel of the image at the target pixel position is adjusted according to the edge pixel feathering algorithm preset in step 502, as shown in fig. 5, which specifically includes:
step 601: acquiring an original pixel value of an image at a specific coordinate of a target pixel position (i-th row and j-th column) from a pre-stored data center according to a pixel position information matching algorithm;
if the original pixel value P (i, j) of the image at the target pixel location is zero,
then, in step 602: adjusting the pixel value of the pixel of the image at the target pixel position by P' (i, j) × a × P (i, j);
if the original pixel value P (i, j) of the image at the target pixel location is greater than or equal to zero,
then, in step 603: adjusting the pixel value of a pixel of the image at the target pixel position by P' (i, j) (1-a) × P (i, j);
wherein: p (i, j) is the pixel value when the specific coordinate of the pixel of the image before the adjustment is located at the position of the (i-th row and j-th column), P' (i, j) is the pixel value when the pixel of the image after the adjustment is located at the position of the target pixel (i-th row and j-th column), a is the gray scale weight of each frame required by the pixel of the image to move from the original pixel position to the target pixel position (i-th row and j-th column), the gray scale weight of each frame is equal to 1 divided by x, wherein x represents the preset number of frames required by the pixel of the image to move from the original pixel position to the target pixel position (i-th row and j-th column), and x is more than or equal to 2.
It should be noted that, the pre-stored data center also stores pixel values corresponding to the positions of the pixels of the image, for example, when the display receives all the electrical signals of the image in sequence and converts all the electrical signals to the output image, the image is stored at the same time at the pixel positions corresponding to the display. Thus, with the above method, for example, when the original pixel value P (i, j) of the image at the target pixel position is zero, if the number of preset frames required to move the pixel of the image from the original position to the target pixel position is 10 frames, a is 1/10 ═ 0.1, and if P' (i, j) ═ a (P (i, j) × 0.1 × 0, the pixel value of the adjusted image at the target pixel position is 0 as well.
If the number of frames required to move the pixel of the image from the original position to the target pixel position is 10 frames when the original pixel value P (i, j) of the image at the target pixel position is 100, a is 1/10 ═ 0.1, and the pixel value of the pixel of the adjusted image at the target pixel position is 90 when P' (i, j) ═ 1-a × P (i, j) ═ 0.9 ═ 100 ═ 90. In the above method, the predetermined number of frames required to move the pixel of the image from the original position to the target pixel position is 5 frames, and if a is 1/5 ═ 0.2, (1-a) P (i, j) is 0.8 × -100 ═ 80 according to P' (i, j), the pixel value of the pixel of the adjusted image at the target pixel position is 80.
In an optional implementation manner, if the pixel of the image is a non-edge pixel, the non-edge pixel feathering algorithm is preset according to step 503 to adjust the pixel value of the pixel of the image at the target pixel position, as shown in fig. 5, which specifically includes:
step 701, respectively acquiring pixel values of pixel specific coordinates of an image at a (ith row, jth-1 column) position and a (ith row, jth column) position from a pre-stored data center according to a pixel position information matching algorithm;
step 702, adjusting the pixel value of the pixel of the image at the target pixel position according to P' (i, j) ═ a × P (i, j-1) + (1-a) × P (i, j);
wherein: p (i, j) is the pixel value when the specific pixel coordinate of the image before the adjustment is located at the (i-th row, j-th column) position, P (i, j-1) is the pixel value when the specific pixel coordinate of the image after the adjustment is located at the (i-th row, j-1-th column) position, P' (i, j) is the pixel value when the pixel of the image after the adjustment is located at the target pixel position (i-th row, j-th column), a is the gray scale weight of each frame required for the pixel of the image to move from the original pixel position to the target pixel position (i-th row, j-th column), the gray scale weight of each frame is equal to 1 divided by x, wherein x represents the preset frame number required for the pixel of the image to move from the original pixel position to the target pixel position (i-th row, j-th column), and x is more than or equal to 2.
By the above method, for example, the pixel values P (i, j) of the image having the pixel specific coordinates at the (i-th row, j-1-th column) position P (i, j-1) and the (i-th row, j-th column) position P (i, j) are 90 and 100, respectively; if the preset frame number required for moving the pixel of the image from the original position to the target pixel position is 10 frames, a is 1/10 ═ 0.1, and according to P' (i, j) ═ a × P (i, j-1) + (1-a) × P (i, j) ═ 0.1 + 90+0.9 ═ 100 ═ 99, the pixel value of the pixel of the adjusted image at the target pixel position is 99. In the above method, the predetermined number of frames required to move the pixel of the image from the original position to the target pixel position is 5 frames, and if a is 1/5.2, the pixel value of the adjusted pixel of the image at the target pixel position is 98 according to P' (i, j) a P (i, j-1) + (1-a) P (i, j) 0.2 + 90+0.8 + 100.
Specifically, by the method in any one of the above-mentioned optional implementation manners, the pixel of the image is controlled to move from the original pixel position to the target pixel position by at least two frames, so that the pixel of the image is prevented from remaining at the original pixel position when the pixel of the image is moved from the original pixel position to the target pixel position by one frame. And the display effect of the image after the movement is effectively improved by adjusting the pixel value of the pixel of the image after the movement at the target pixel position.
In a second aspect, in order to eliminate the pixel residue of the image on the display and effectively improve the display effect of the image after the movement by moving the image displayed by the display and adjusting the pixel value of the pixel of the image after the movement at the target pixel position, the present invention further includes an apparatus for processing the image of the display, as shown in fig. 7, the apparatus includes:
a display for displaying a still image;
and the control output module is used for controlling the pixel of the image to move from the original pixel position to the target pixel position by at least two frames and adjusting the pixel value of the pixel of the image at the target pixel position.
Specifically, the display is provided with a signal receiving module and a signal conversion module, and can acquire an electrical signal of an image through the signal receiving module and convert and output the electrical signal through the signal conversion module, so that the image is displayed on the display. Displays include, but are not limited to: cell-phone, panel computer, intelligent wrist-watch, virtual reality equipment, display device.
The display may be configured to receive an electrical signal of an image and display the image, where the image may be a still image or a moving image.
In an alternative implementation, the apparatus for image processing of a display further includes a motion detection module configured to detect a state of an image displayed on the display.
It should be noted that the motion detection module may detect whether the image displayed on the display is in a still state or a motion state through two alternative implementations.
In a first optional implementation manner, the motion detection module is specifically configured to:
calculating the time when the image is still at any position of the display;
judging whether the time for which the image is static at any position of the display is greater than or equal to a first preset time or not;
if the time for which the image is static at any position of the display is greater than or equal to a first preset time, determining that the image displayed on the display is in a static state;
and if the time for which the image is static at any position of the display is less than the first preset time, determining that the image displayed on the display is in a motion state.
In a second optional implementation manner, the motion detection module is specifically configured to:
calculating the number of image frames displayed by the display in a second preset time;
judging whether the number of frames of the image displayed by the display in the second preset time is smaller than a first preset value or not;
if the frame number of the image displayed by the display in the second preset time is smaller than the first preset value, determining that the image displayed on the display is in a static state;
and if the frame number of the image displayed by the display in the second preset time is greater than or equal to the first preset value, determining that the image displayed on the display is in a motion state.
The motion detection module may determine whether the image is still on the display, for example, within 1 second, the display should display 60 frames of images, and if the second preset time is also 1 second, and the display displays 5 frames of images within another 1 second, it indicates that the image displayed on the display is still within a certain time. If the display shows 60 frames of images in another 1 second, it may indicate that the images shown on the display are moving within that 1 second. Therefore, whether the image displayed on the display is static or moving can be judged by calculating the total frame number of the image displayed by the display in the second preset time through the motion detection module.
In an alternative implementation, the pixels of the image displayed on the display are moved when the motion detection module finds that the image displayed on the display is in a static state. The device for processing the display image also comprises a moving path processing module and an information processing module;
the information processing module is used for identifying original pixel position information of pixels of the image from a pre-stored data center according to a pixel position information matching algorithm;
the moving path processing module is specifically configured to:
according to original pixel information of pixels of the image identified by the information processing module, a moving path bound by the pixels containing the image moving from an original pixel position to a target pixel position is obtained according to a preset pixel position information matching algorithm;
if the moving path is one, the control output module controls the pixels of the image to move from the original pixel position to the target pixel position through at least two frames along the moving path;
if the moving paths are two or more than two, the control output module prompts a user to select one moving path from the moving paths, and the pixels of the image are moved from the original pixel position to the target pixel position at least through two frames by adopting the moving path corresponding to the user selection result.
It should be noted that the movement path processing module is configured to acquire a movement path to which pixels of the image move from the original pixel position to the target pixel position, and specifically includes, as shown in fig. 6, a movement path that can be selected by the movement path processing module when the pixels of the image move from a position of a specific coordinate a (i-th row, j-th column) of the display to a position of another specific coordinate B (i + 1-th row, j-1-th column) of the display, and the pixels of the image can be controlled by the output module to move from a specific coordinate a point to a specific coordinate B point along the movement path at least through two frames by moving the pixels of the image from the original pixel position to the target pixel position through a square as shown in (1) in fig. 6, (2) a parallelogram in fig. 6, or (3) an octagon in fig. 6.
In an optional implementation manner, in order to adjust a pixel value of a pixel of an image at a target pixel position, the apparatus for processing an image on a display further includes an edge pixel position determining module, which is specifically configured to:
identifying whether the pixel is an edge pixel from a pre-stored data center according to the original pixel position information of the pixel of the image identified by the information processing module and a pixel position information matching algorithm;
if the pixel of the image is an edge pixel, controlling an output module to adjust the pixel value of the pixel of the image at the target pixel position according to a preset edge pixel eclosion algorithm;
if the pixel of the image is a non-edge pixel, the control output module adjusts the pixel value of the pixel of the image at the target pixel position according to a preset non-edge pixel eclosion algorithm.
It should be noted that, for example, if the display receives all the row electrical signals of the image in sequence, the position of the pixel of the image displayed after the first row electrical signal and the last row electrical signal are converted is the edge pixel position, then the display receives all the column electrical signals of the image in sequence, the position of the pixel of the image displayed after the first column electrical signal and the last column electrical signal are converted is the edge pixel position, the pixels of all the edge pixel positions are all indexed as edge pixels, the positions of the pixels of the image displayed after the other electrical signals are converted are non-edge pixel positions, and the pixels of all the non-edge pixel positions are indexed as non-edge pixels. Therefore, when the location information of the pixels of the image is recognized from the pre-stored data center according to the pixel location information matching algorithm, it can be recognized whether the pixels of the pixel location of the image are edge pixels.
In an optional implementation manner, the information processing module is further configured to obtain, from a pre-stored data center, an original pixel value of the image at a specific coordinate of the target pixel position in (i-th row, j-th column) according to a pixel position information matching algorithm;
when the pixels of the image are edge pixels, the control output module is specifically configured to:
if the original pixel value P (i, j) of the image at the target pixel position is zero, adjusting the pixel value of the pixel of the image at the target pixel position according to P' (i, j) (1-a) × P (i, j);
if the original pixel value P (i, j) of the image at the target pixel position is greater than or equal to zero, adjusting the pixel value of the pixel of the image at the target pixel position according to P' (i, j) ═ a × P (i, j);
wherein: p (i, j) is the pixel value when the specific coordinates of the pixels of the image before the adjustment are located at the position (i th row, j th column), P' (i, j) is the pixel value when the pixels of the image after the adjustment are located at the target pixel position (i th row, j th column), a is the gray scale weight of each frame required by the pixels of the image to move from the original pixel position to the target pixel position (i th row, j th column), the gray scale weight of each frame is equal to 1 divided by x, wherein x represents the preset number of frames required by the pixels of the image to move from the original pixel position to the target pixel position (i th row, j th column), and x is more than or equal to 2.
With the above-described device, for example, when the original pixel value P (i, j) of the image at the target pixel position is zero, if the number of preset frames required to move the pixel of the image from the original position to the target pixel position is 10 frames, a is 1/10 ═ 0.1, and if P' (i, j) ═ a (i, j) ═ 0.1 × 0, the pixel value of the adjusted image at the target pixel position is 0.
If the number of frames required to move the pixel of the image from the original position to the target pixel position is 10 frames when the original pixel value P (i, j) of the image at the target pixel position is 100, a is 1/10 ═ 0.1, and the pixel value of the pixel of the adjusted image at the target pixel position is 90 when P' (i, j) ═ 1-a × P (i, j) ═ 0.9 ═ 100 ═ 90. In the above method, the predetermined number of frames required to move the pixel of the image from the original position to the target pixel position is 5 frames, and if a is 1/5 ═ 0.2, (1-a) P (i, j) is 0.8 × -100 ═ 80 according to P' (i, j), the pixel value of the pixel of the adjusted image at the target pixel position is 80.
In an optional implementation manner, the information processing module is further configured to obtain, according to a pixel location information algorithm, pixel values of pixels of the image, which are specifically located at an (i, th (j-1)) position and an (i, th) position, from a pre-stored data center respectively;
when the pixels of the image are non-edge pixels, the control output module is specifically configured to:
adjusting the pixel value of the pixel of the image at the target pixel position according to P' (i, j) ═ a × P (i, j-1) + (1-a) × P (i, j);
wherein: p (i, j) is the pixel value when the specific pixel coordinate of the unadjusted image is at the (ith row, jth column) position, P (i, j-1) is the pixel value when the specific pixel coordinate of the adjusted image is at the (ith row, jth column) position, P' (i, j) is the pixel value when the pixel of the adjusted image is at the target pixel position (ith row, jth column), a is the gray scale weight of each frame required for the pixel of the image to move from the original pixel position to the target pixel position (ith row, jth column), the gray scale weight of each frame is equal to 1 divided by x, wherein x represents the preset frame number required for the pixel of the image to move from the original pixel position to the target pixel position (ith row, jth column), and x is more than or equal to 2.
With the above arrangement, for example, the pixel values P (i, j) of the image at the (i-th row, j-1-th column) position P (i, j-1) and the (i-th row, j-th column) position P (i, j) are 90 and 100, respectively; if the preset frame number required for moving the pixel of the image from the original position to the target pixel position is 10 frames, a is 1/10 ═ 0.1, and according to P' (i, j) ═ a × P (i, j-1) + (1-a) × P (i, j) ═ 0.1 + 90+0.9 ═ 100 ═ 99, the pixel value of the pixel of the adjusted image at the target pixel position is 99. In the above method, the predetermined number of frames required to move the pixel of the image from the original position to the target pixel position is 5 frames, and if a is 1/5.2, the pixel value of the adjusted pixel of the image at the target pixel position is 98 according to P' (i, j) a P (i, j-1) + (1-a) P (i, j) 0.2 + 90+0.8 + 100.
Specifically, with the apparatus in any one of the above-described alternative implementations, the pixels of the image are moved from the original pixel positions to the target pixel positions by at least two frames, so that the pixels of the image are prevented from remaining at the original pixel positions when the pixels of the image are moved from the original pixel positions to the target pixel positions by one frame. And the pixel value of the pixel of the image after the movement at the target pixel position is adjusted, so that the display effect of the image after the movement is effectively improved.
