Wearable devices include, for example, smartwatches, smart bracelets, pedometers, etc.

[0035] Combination Figure 1 As shown, this disclosure provides a method for automatically adapting to a display screen, including:

[0036] S01, the electronic device obtains the size parameters of the target display screen and the display parameters of the display content on the current display screen.

[0037] S02, the electronic device determines the display area and display size of the display content on the target display screen based on the size parameters and display parameters.

[0038] In this technical solution, the electronic device determines the ideal display parameters of the content on the target display screen based on the size parameters of the target display screen and the display parameters of the content on the current display screen. In practical applications, the display area of ​​the content on the target display screen can be determined by the distance of the content from the height-related edge and the distance of the content from the width-related edge on the target display screen. In practical applications, the display size of the content on the target display screen can be the target width and the target height of the content.

[0039] S03, the electronic device iteratively adjusts the size of the displayed content so that the displayed content is displayed in the display area according to the display size.

[0040] In this technical solution, the electronic device iteratively adjusts the size of the displayed content, which can be done by adjusting the height and width of the displayed content proportionally. The adjustment range of each iteration cycle can be understood as the adjustment step size of the current iteration cycle.

[0041] The method for automatically adapting to a display screen provided in this disclosure obtains the size parameters of the target display screen and the display parameters of the content to be displayed on the current display screen, determines the ideal display parameters of the content on the target display screen, and performs proportional iterative adjustments to the content by calculating the rate of change of width and height during the adjustment process. This effectively reduces the impact of image distortion, improves the accuracy of adjustment control, and enhances the user experience.

[0042] Optionally, the size parameters of the target display screen include the width and height of the target display screen; the display parameters of the display content on the current display screen include the width of the display content, the height of the display content, the width of the current display screen, the height of the current display screen, and the relative position of the display content on the current display screen.

[0043] In some alternative implementations, combined with Figure 2 As shown in the embodiments of this disclosure, another method for automatically adapting to a display screen may include:

[0044] S11, the electronic device obtains the size parameters of the target display screen and the display parameters of the display content on the current display screen.

[0045] S12, the electronic device determines the display area and display size of the display content on the target display screen based on the size parameters and display parameters.

[0046] S13, the electronic device acquires the display orientation of the displayed content and the display orientation of the target display screen.

[0047] S14, if the display orientation of the displayed content is inconsistent with the display orientation of the target display screen, the electronic device rotates the displayed content to be consistent with the display orientation of the target display screen.

[0048] S15, the electronic device iteratively adjusts the size of the displayed content so that the displayed content is displayed in the display area according to the display size.

[0049] In practical applications, when adapting an image from a mobile phone screen to a computer screen, the mobile phone screen is the current display, and the computer screen is the target display. The image's display orientation on the mobile phone screen is the horizontal direction of the coordinate system, while the computer screen's display orientation is the vertical direction. That is, after obtaining the size parameters of the computer screen and the image's display parameters on the mobile phone screen, the image's display orientation needs to be rotated to match the computer screen's orientation. It should be understood that during this rotation, the image's size and position information remain unchanged.

[0050] In this way, by pre-adjusting the display orientation of the content to match that of the target display screen, the display content can avoid failing to achieve the expected display effect during the screen adaptation process, thus providing a basis for subsequent adjustments to the display content.

[0051] Optionally, based on size parameters and display parameters, the electronic device determines the display area and display size of the displayed content on the target display screen, including:

[0052] Calculate c1 = c2 × α1 to obtain the target height c1 of the displayed content;

[0053] Calculate c3 = c4 × α2 to obtain the target width c3 of the displayed content;

[0054] Calculate d1 = d2 × α1 to obtain the distance d1 of the displayed content on the edge of the target display screen related to its height;

[0055] Calculate d3 = d4 × α2 to obtain the distance d3 of the displayed content on the side of the target display screen related to its width;

[0056] The display size of the content on the target display screen is determined according to the target height c1 and the target width c3;

[0057] Based on distances d1 and d3, determine the display area of ​​the content on the target display screen;

[0058] Where α1 represents the height conversion coefficient of the displayed content, α2 represents the width conversion coefficient of the displayed content, c2 represents the height of the displayed content on the current screen, c4 represents the width of the displayed content on the current screen; d2 represents the distance of the displayed content on the current screen relative to the height, and d4 represents the distance of the displayed content on the current screen relative to the width; where α1 is determined based on the height of the target screen and the height of the current screen, and α2 is determined based on the width of the target screen and the width of the current screen.

[0059] Optionally, the electronic device determines α1 based on the height of the target display screen and the current display screen height, including:

[0060] calculate Obtain the height conversion factor α1 of the displayed content;

[0061] Where a1 represents the height of the target display screen and b1 represents the height of the current display screen.

[0062] Optionally, the electronic device determines α2 based on the width of the target display screen and the width of the current display screen, including:

[0063] calculate Obtain the width conversion factor α2 of the displayed content;

[0064] Where a2 represents the width of the target display screen and b2 represents the width of the current display screen.

[0065] In practical applications, when adapting a text box from a smartwatch screen to a mobile phone screen, the smartwatch screen is the current display, and the mobile phone screen is the target display. It should be understood that the text box has automatic line wrapping, and the font size adjusts according to the text box size. The smartwatch screen can be 35 mm wide and 40 mm high, while the mobile phone screen can be 70 mm wide and 160 mm high. The width and height of the text box can be expressed in millimeters, centimeters, or other units of length, or they can be represented by the distance between corresponding points related to the text box's width or height within the coordinate area of ​​the current display screen. This application does not impose specific limitations on this, as long as it reflects the width and height of the text box. If the current width of the text box is 4 and the current height is 7, based on the above size parameters, the height conversion factor α1 of the displayed content is 4, and the width conversion factor α2 of the displayed content is 2. Therefore, the target height c1 of the displayed content is determined to be 28, and the target width c3 of the displayed content is determined to be 8.

[0066] In this way, by calculating the height conversion factor and the width conversion factor of the displayed content, the display size of the displayed content in the ideal display parameters of the target display is determined, providing a data basis for subsequent adjustments to the displayed content.

[0067] In this technical solution, the distance d2 of the displayed content relative to the height of the current display screen and the distance d4 of the displayed content relative to the width of the current display screen can be determined based on the relative position of the displayed content on the current display screen. It should be understood that, when the relative position of the displayed content on the current display screen is known, the distance between the displayed content and the edge representing the height of the current display screen can be obtained, which is equivalent to d2; similarly, it should be understood that, when the relative position of the displayed content on the current display screen is known, the distance between the displayed content and the edge representing the width of the current display screen can be obtained, which is equivalent to d4.

[0068] Optionally, the distance d2 of the displayed content on the edge related to the height of the current display screen can be the distance between the center point of the displayed content and the edge representing the height of the current display screen.

[0069] Optionally, the distance d2 of the displayed content on the edge related to the height of the current display screen can be the distance between any point on one edge of the displayed content and the edge representing the height of the current display screen.

[0070] Optionally, the distance d4 of the displayed content on the edge related to the width of the current display screen can be the distance between the center point of the displayed content and the edge representing the width of the current display screen.

[0071] Optionally, the distance d4 of the displayed content on the edge related to the width of the current display screen can be the distance between any point on one edge of the displayed content and the edge representing the width of the current display screen.

[0072] In practical applications, when adapting an image from a computer screen to a smart TV screen, the computer screen is the current display, and the smart TV screen is the target display. With both the computer screen and the smart TV screen placed vertically on the ground, the side closest to the ground is considered the bottom edge of the display, the side opposite the bottom edge is considered the top edge, and the two edges adjacent to the bottom edge are considered the first and second side edges, respectively. That is, the distance from any point on one edge of the image to the first or second side edge of the computer screen is equivalent to the distance d2 of the displayed content on the current screen relative to its height in this technical solution; the distance from any point on one edge of the image to the bottom or top edge of the computer screen is equivalent to the distance d4 of the displayed content on the current screen relative to its width in this technical solution. It should be understood that the distance from the point on the image that is identical to the determined d2 to the first or second side of the smart TV display screen is equivalent to the distance d1 of the display content on the target display screen relative to its height in this technical solution; the distance from the point on the image that is identical to the determined d4 to the bottom or top side of the smart TV display screen is equivalent to the distance d3 of the display content on the target display screen relative to its width in this technical solution.

[0073] In this way, by determining the distance of the displayed content to the height-related edge of the target display screen, and the distance of the displayed content to the width-related edge of the target display screen, the display area of ​​the displayed content in the ideal display parameters of the target display screen is determined, providing a data basis for the subsequent adaptation of the displayed content to the target display screen.

[0074] In some alternative implementations, combined with Figure 3 As shown, this disclosure provides an iterative adjustment flowchart in which an electronic device iteratively adjusts the size of displayed content, including:

[0075] S21, the height β of the displayed content is adjusted for the i-th time. i and the width δ of the displayed content i .

[0076] S22, determine the height change rate Eβ of the displayed content after the i-th adjustment. i and the rate of change of width Eδ i .

[0077] S23, if Eβi or Eδ i If a change in value occurs (positive or negative), stop adjusting the height and width of the displayed content; otherwise, continue adjusting the height β of the displayed content for the (i+1)th time. i+1 and the width δ of the displayed content i+1 Where i is a positive integer greater than 0.

[0078] Optionally, the height β of the displayed content is adjusted for the i-th time. i ,include:

[0079] Calculate β i =β i-1 +e i1 Get the height β of the displayed content after the i-th adjustment. i ;

[0080] Where, β i-1 This indicates the (i-1)th adjustment of the displayed content height, e i1 This indicates the step size for iteratively adjusting the height of the displayed content in the i-th iteration.

[0081] Optionally, the width δ of the displayed content is adjusted for the i-th time. i ,include:

[0082] Calculate δ i =δ i-1 +e i2 Obtain the width δ of the displayed content during the i-th adjustment. i ;

[0083] Where, δ i-1 This indicates the (i-1)th adjustment of the width of the displayed content, e i2 This indicates the step size for iterative adjustment of the displayed content width in the i-th iteration.

[0084] In this technical solution, it should be understood that e i1 With e i2 The value of can be positive or negative.

[0085] In practical applications, when adapting a text box from a computer screen to a mobile phone screen, the computer screen is the current display, and the mobile phone screen is the target display. It should be understood that the height β of the displayed content is adjusted starting from the i-th time. i and the width δ of the displayed content i Previously, the text box's height was determined by its position on the computer screen, and its width by its position on the mobile phone screen. In practical applications, the height β of the displayed content is adjusted starting from the i-th time. i and the width δ of the displayed content iPreviously, if the height of the text box was 50 and the width was 30, the first iteration of height adjustment for the displayed content would have a step size e. 11 The value is negative 10, and the step size e is adjusted in the second height iteration of the displayed content. 21 The value is negative 5, and the first iteration of the width adjustment step is e. 12 The value is negative 6, and the first iteration of the width adjustment step is e. 22 The value is -3. After the first adjustment, the corresponding β1 value is 40 and δ1 value is 24. After the second adjustment, the corresponding β1 value is 35 and δ1 value is 21, and so on for the remaining adjustments.

[0086] Optionally, e i1 e i2 The proportional relationship is the same as that of β0 and δ0.

[0087] Where β0 represents the height of the displayed content on the current screen, and δ0 represents the width of the displayed content on the current screen.

[0088] In some alternative implementations, e i1 With e i2 The value can be preset.

[0089] Optionally, e i1 With e i2 The value can be fixed.

[0090] Optionally, e i1 With e i2 The value can be variable.

[0091] In some alternative implementations, e i1 The value of satisfies |e i1 |greater than|e i+11 |,e i2 The value of satisfies |e i2 |greater than|e i+12 |

[0092] In practical applications, it should be understood that, in order to reduce the number of operations performed by electronic devices, the e in the initial stage of iteration... i1 With e i2 The absolute value of the value should be greater than e before the iteration stops. i1 With e i2 The absolute value of the value, i.e., e 11 The absolute value is greater than e 21 The absolute value of e; 12 The absolute value is greater than e 22 The absolute value of.

[0093] By using height and width iteration adjustment steps that are proportional to the width and height of the displayed content on the current screen, the width and height of the displayed content can be adjusted proportionally. This effectively reduces the impact of image distortion, improves the accuracy of adjustment control, and enhances the user experience.

[0094] Optionally, the electronic device determines the height variation rate Eβ of the displayed content in the following manner. i and the rate of change of width Eδ i :

[0095] calculate Obtain the height change rate of the displayed content after the i-th adjustment. Where t is the sampling period of the iterative adjustment.

[0096] Optionally, the electronic device determines the width variation rate Eδ of the displayed content in the following manner. i :

[0097] calculate Obtain the rate of change of the width of the displayed content after the i-th adjustment. Where t is the sampling period of the iterative adjustment.

[0098] In practical applications, if Eβ i or Eδ i The fact that adjustments to the height and width of the displayed content cease when a positive or negative value changes can be understood as determining Eβ. i-1 With Eβ i The positive or negative value state, or to determine Eδ i-1 With Eδ i The positive and negative states, in Eβ i-1 With Eβ i , or Eδ i-1 With Eδ i If the positive or negative value of Eβ changes, the adjustment of the height and width of the displayed content stops. It should be understood that during the adaptation process from the current display to the target display, if the size of the current display is smaller than the size of the target display, Eβ is adjusted in each iteration. i With Eδ i It's a gradual reduction process; if the current display size is larger than the target display size, Eβ is adjusted in each iteration. i With Eδ i It's a gradual process. In Eβ i or Eδ i When the positive or negative value of a certain term in Eβ changes, that is, when the change occurs... i or Eδ i The corresponding adjusted height or width of the displayed content reaches or exceeds the display size. It should be understood that in Eβ... ior Eδ i When one of the terms takes a value of zero, it is equivalent to Eβ. i or Eδ i The width or height of the corresponding display content achieves the ideal display parameters for the content on the target display screen.

[0099] In this way, by judging whether the positive or negative value of the height change rate or width change rate of the displayed content changes after the i-th adjustment, the termination condition of the iterative adjustment process of stopping the displayed content can be used to effectively avoid data oscillations that occur when the displayed content fails to reach the display size in the ideal display parameters of the target display screen without distortion.

[0100] Combination Figure 4 As shown in the embodiments of this disclosure, another method for automatically adapting to a display screen is provided, including:

[0101] S31, the electronic device acquires the size parameters of the target display screen and the display parameters of the display content on the current display screen.

[0102] S32, the electronic device determines the display area and display size of the display content on the target display screen based on the size parameters and display parameters.

[0103] S33, the electronic device performs its first iterative adjustment to the size of the displayed content.

[0104] S34, the electronic device obtains the display content height iteration adjustment step size, display content width iteration adjustment step size, and the current size of the display content when the first iteration adjustment stops.

[0105] S35, when the height and width change rates of the displayed content change in the first iteration change state change, the electronic device determines the second iteration adjustment step size of the displayed content height and the second iteration adjustment step size of the displayed content width based on the iterative adjustment step size of the displayed content height and the iterative adjustment step size of the displayed content width.

[0106] In practical applications, it should be understood that after the first iteration of adjusting the size of the displayed content, the size of the displayed content has reached or is close to the display size. That is, the change in the height and width change rates of the displayed content during the first iteration can be understood as the size of the displayed content approaching the display size.

[0107] S36, the electronic device performs a second iteration to adjust the current size of the displayed content so that the displayed content is displayed in the display area according to the display size.

[0108] In this way, by obtaining the size parameters of the target display screen and the display parameters of the content to be displayed on the current display screen, the ideal display parameters of the content on the target display screen are determined. By calculating the rate of change of width and height during the adjustment of the display content, and by performing two different iterative adjustments on the display content, the impact of image distortion is further reduced, the accuracy of adjustment control is improved, and the user experience is enhanced.

[0109] Optionally, the step size for the second iteration adjustment of the display content height and the second iteration adjustment step size of the display content width are determined based on the iterative adjustment step size of the display content height and the display content width, including:

[0110] With a fixed coefficient, reduce the iteration adjustment step size of the display content height and the iteration adjustment step size of the display content width at the stop state of the first iteration adjustment; use the reduced iteration adjustment step size of the display content height as the iteration adjustment step size of the second iteration adjustment of the display content height; use the reduced iteration adjustment step size of the display content width as the iteration adjustment step size of the second iteration adjustment of the display content width.

[0111] In this technical solution, the fixed coefficient can be 17%, 20%, 5% or other values, and this application does not make a specific limitation on it.

[0112] In practical applications, if the display content height is adjusted by a step size of 20 and the display content width by a step size of 15, with a fixed coefficient of 10%, when the first iteration of adjustment stops, then the second iteration of adjustment for the display content height will be 2 and the second iteration of adjustment for the display content width will be 1.5.

[0113] In this way, by obtaining the size parameters of the target display screen and the display parameters of the content to be displayed on the current display screen, the ideal display parameters of the content on the target display screen are determined. By calculating the rate of change of width and height during the adjustment of the display content, and by performing two different iterative adjustments on the display content, the impact of image distortion is further reduced, the accuracy of adjustment control is improved, and the user experience is enhanced.

[0114] In some alternative implementations, combined with Figure 5 As shown, this disclosure provides a flowchart of another iterative adjustment. The electronic device performs a second iterative adjustment to the current size of the displayed content, including:

[0115] S41, the height β of the displayed content is adjusted for the j-th time. j and the width δ of the displayed content j .

[0116] S42, determine the height change rate Eβ of the displayed content after the j-th adjustment. j and the rate of change of width Eδj .

[0117] S43, if Eβ j or Eδ j If a change in value occurs (positive or negative), stop adjusting the height and width of the displayed content; otherwise, continue adjusting the height β of the displayed content for the (j+1)th time. j+1 and the width δ of the displayed content j+1 .

[0118] Where j is a positive integer greater than 0.

[0119] Optionally, the height β of the displayed content is adjusted for the j-th time. j ,include:

[0120] Calculate β j =β j-1 +e j1 Obtain the height β of the displayed content after the j-th adjustment. j ;

[0121] Where, β j-1 This indicates the (j-1)th adjustment of the displayed content height, e j1 This indicates the step size for iteratively adjusting the height of the displayed content in the j-th iteration.

[0122] Optionally, the width δ of the displayed content is adjusted for the j-th time. j ,include:

[0123] Calculate δ j =δ j-1 +e j2 Obtain the width δ of the displayed content during the j-th adjustment. j ;

[0124] Where, δ j-1 This indicates the (j-1)th adjustment of the displayed content width, e j2 This indicates the step size for iterative adjustment of the displayed content width in the j-th iteration.

[0125] Optionally, the height variation rate Eβ of the displayed content is determined as follows: j and the rate of change of width Eδ j :

[0126] calculate Obtain the height change rate of the displayed content after the j-th adjustment. Where t is the sampling period of the iterative adjustment.

[0127] Optionally, the width variation rate Eδ of the displayed content is determined as follows: j :

[0128] calculate Obtain the rate of change of the width of the displayed content after the j-th adjustment. Where t is the sampling period of the iterative adjustment.

[0129] In practical applications, it should be understood that before the electronic device performs a second iteration to adjust the current size of the displayed content, the dimensions corresponding to the current size of the displayed content are the current sizes of the displayed content at the state where the first iteration stopped. That is, the height and width of the displayed content at the time the first iteration stopped.

[0130] In this way, by obtaining the size parameters of the target display screen and the display parameters of the content to be displayed on the current display screen, the ideal display parameters of the content on the target display screen are determined. By calculating the rate of change of width and height during the adjustment of the display content, and by performing two iterative adjustments of different lengths on the display content, the impact of image distortion is further reduced, the accuracy of adjustment control is improved, and the user experience is enhanced.

[0131] In some alternative implementations, combined with Figure 6 As shown in the embodiments of this disclosure, another method for automatically adapting to a display screen may include:

[0132] S51, the electronic device obtains the size parameters of the target display screen and the display parameters of the text box on the current display screen.

[0150] It should be understood that the position of the text box on the current screen is fixed. By using the text box as a reference, the distance between the first line of characters and the two sides of the text box can be determined, and thus the character display area of ​​the first line of characters on the current screen can be determined.

[0151] In some alternative implementations, the reference is the current display screen, and obtaining the character display area of ​​the first line of the text box on the current display screen includes:

[0152] Get the distance d between the first line of characters and the two edges of the current display screen. a With distance d b .

[0170] Where, δ k-1 This indicates the (k-1)th adjustment of the displayed content width, e k This indicates the step size for iterative adjustment of the displayed content width in the kth iteration.

[0171] In practical applications, the character size of the first line of characters in a text box on the current display screen can be 14pt, 20pt, small four, five, or other expressions used to indicate character font size; this application does not specifically limit this. It should be understood that e k It can be represented as 1pt or a font size, e k The value of Eδ can be positive or negative. It should be understood that during the adaptation process from the current display to the target display, if the size of the current display is smaller than the size of the target display, Eδ is adjusted in each iteration. k It's a gradual reduction process; if the current display size is larger than the target display size, Eδ is adjusted in each iteration. k It is a gradual process of increase.

[0172] Optionally, the width variation rate Eδ of the first line of characters in the text box is determined as follows: k :

[0177] In practical applications, it should be understood that... Figure 6In S54, the display parameters of the first line of characters in a text box on the current screen can be obtained. Figure 4 S36 is executed after the second iteration adjusts the current size of the displayed content. The displayed content mentioned in S36 corresponds to the text box mentioned in S54. Subsequent execution steps are the same as... Figure 6 The same applies to S54 to S57, and will not be repeated here.

[0178] In this way, when the displayed content is a text box, and the text size does not adjust with the size of the text box, after iterative adjustments of the text box are completed, the text within the text box is adjusted to fit the target display screen. This improves the accuracy of adjustment control and enhances the user experience.
