Description

Technical Field

[0001] The embodiments of the present application relate to the field of information technology, and in particular to a method, device and medical equipment for improving image display stability. Background Art

[0002] In information technology, after receiving data from a sender, a receiver often needs to visualize the received data, that is, generate a corresponding image based on the data provided by the background using tools such as a rendering engine, and display the image, which may be in the form of an animation.

[0003] In a real-time communications scenario, a sender continuously sends data at a predetermined frequency over a period of time. The data is transmitted to a receiver through a communication network. The receiver visualizes the data and displays a continuous animation on the display.

[0004] For example, in the field of medical equipment, medical equipment continuously detects to obtain the physiological parameters of the detected object and sends the physiological parameters to the receiving end. The medical staff at the receiving end can understand the physiological parameters of the detected object through the images displayed on the monitor.

[0005] In addition, in some other scenarios, the transmitting end may send data as a video stream to the receiving end, and the receiving end processes the data to display the video on a display.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0007] The inventors of the present application discovered that the frequency at which a transmitter sends data to a receiver sometimes fluctuates, and the communication quality of a communication network sometimes fluctuates. As a result, the frequency at which a receiver receives data (or the time interval between receiving two segments of data) also fluctuates, causing the video or animation displayed by the receiver to be discontinuous (i.e., unstable image display).

[0008] In order to solve at least the above-mentioned technical problems or similar technical problems, the embodiments of the present application provide a method, an apparatus and a medical device for improving the stability of image display. In the method, the display duration of the image corresponding to the data is set according to the change information of the time interval for receiving data at the receiving end. Thus, even if there is jitter in the receiving frequency of the data, such jitter can be absorbed by adjusting the display duration of the image, thereby avoiding the problem of discontinuity in image display.

[0009] According to one aspect of an embodiment of the present application, a method for improving image display stability is provided, the method comprising:

[0010] Calculating information on changes in the time interval at which the receiving end receives data within a predetermined time period; and

[0011] The display duration of the image corresponding to the data received by the receiving end after the predetermined time period is set based on the change information.

[0012] According to one aspect of an embodiment of the present application, a device for improving image display stability is provided, the device comprising:

[0013] a change information calculation device, which calculates the change information of the time interval of receiving data at the receiving end within a predetermined time period; and

[0014] A setting device is used to set the display time of the image corresponding to the data received by the receiving end after the predetermined time period based on the change information.

[0015] According to one aspect of an embodiment of the present application, a storage medium storing a computer-readable program is provided, wherein the computer-readable program enables a computer to execute the method for improving image display stability described in the aforementioned aspect.

[0016] According to one aspect of an embodiment of the present application, a medical device is provided, comprising the device for improving image display stability as described in the aforementioned aspect.

[0017] The beneficial effect of the embodiments of the present application is that even if there is jitter in the data receiving frequency, such jitter can be absorbed by adjusting the display duration of the image, thereby avoiding the problem of discontinuous image display.

[0035] Embodiments of the first aspect

[0036] The embodiment of the first aspect of the present application provides a method for improving image display stability.

[0037] Figure 1 is a schematic diagram of a method for improving image display stability according to an embodiment of the first aspect, such as Figure 1 As shown, the method includes:

[0038] Operation 101, calculating change information of a time interval for receiving data at a receiving end within a predetermined time period; and

[0039] Operation 102: Setting, based on the change information, a display duration of an image corresponding to data received by the receiving end after the predetermined time period.

[0040] Based on the embodiment of the first aspect of the present application, the display duration of the image corresponding to the data is set according to the change information of the time interval for receiving data at the receiving end. Therefore, even if the receiving frequency of the data at the receiving end is jittered, such jitter can be absorbed by adjusting the display duration of the image, thereby avoiding the problem of discontinuous image display.

[0041] In at least one embodiment, a receiving end may receive data from a sending end. Figure 2 is a schematic diagram of the receiving and sending ends. Figure 2 As shown, the transmitting end 201 can send data to the receiving end 202 at a predetermined frequency, and the receiving end 202 receives the data sent by the transmitting end 201 through the communication network 203. The transmitting end 201 can be, for example, a device for detecting physiological parameters of an organism (for example, an ultrasonic detection probe, a heart rate detection instrument, etc.), and the receiving end 202 can have a display 204 or the receiving end 202 can be connected to the display 204, so that the image corresponding to the data received by the receiving end 202 can be displayed on the display. The data received by the receiving end 202 can be converted into an animation based on the tool of the rendering engine, or the data received by the receiving end 202 is a video stream, and a video can be formed by appropriately processing the video stream. The communication network 203 can be a wired communication network or a wireless communication network, etc. In addition, the transmitting end 201 and the receiving end 202 can be used not only for medical purposes, but also in other fields, such as traffic monitoring, transaction information monitoring, etc.

[0042] Figure 3 It is a schematic diagram of the data received by the receiving end and the corresponding image. Figure 3 As shown, it is assumed that the receiving end 202 receives a set of data in a time period, the set of data has n segments, n is a natural number, and the n segments of data are represented as d1, d2, d3, ..., d n ;

[0043] The time when the receiving end 202 receives each segment of data is b1, b2, b3, ..., b n ;

[0044] For the kth (k is a natural number less than or equal to n) segment of data in the group of data, the receiving time interval X between two adjacent segments of data k Represented as X k =b k -b k-1 ;

[0045] Assume that the predetermined time interval for sending each segment of data by the sender 201 is T s , T s For example, 1000ms;

[0046] Since the frequency of data transmission by the transmitting end 201 may fluctuate and / or the communication quality of the communication network 203 may fluctuate, the receiving time interval X of each segment of data received by the receiving end 202 may be greater than the receiving time interval X of each segment of data received by the receiving end 202. k Relative to the scheduled transmission time interval T s There is fluctuation, which reflects the change of the time interval for receiving data by the receiving end 202. The fluctuation is expressed as the receiving time interval X of adjacent data. k The scheduled sending time interval T s The difference between k , the difference Y k It can be represented as Y k =X k -Ts;

[0047] For this set of data, the difference Y k can be accumulated, and the accumulated difference △Y can be the sum of the absolute values ​​of the differences in the set of data. For example, the accumulated difference △Y is expressed as

[0048] △Y=|Y1|+|Y2|+|Y3|+……+|Y n |;

[0049] The images corresponding to each segment of data are represented as p1, p2, p3, ..., p n ;

[0050] The predetermined display time of each image may be expressed as T, for example, T=1000 milliseconds (ms);

[0051] The actual display time of each image in the display 204 can be represented as t1, t2, t3, ..., t n ;

[0052] There may be a deviation between the scheduled display time and the actual display time of each image. Therefore, for this set of data, the deviation can be accumulated, and the accumulated deviation ΔA can be expressed as

[0053] △A=T-t1+T-t2+T-t3+……+Tt n ;

[0054] In the above operation 102 of the present application, based on the change information of the time interval of receiving data by the receiving end 202 within the predetermined time period, the display time length of the image corresponding to the k-th data segment based on the time sequence in at least one group of data received by the receiving end 202 after the predetermined time period can be set (where k is a natural number, and k is less than or equal to the number of data segments n in the group of data). For example, based on the predetermined display time length T, the display time length T of the image corresponding to the k-th data segment is set to m Thus, the display duration of the image corresponding to the k-th segment of data can be used to digest the change in the time interval of the above-mentioned received data, thereby ensuring the display continuity of the entire group of images.

[0055] In a specific example, k can be 1, that is, the display duration of the image corresponding to the first segment of data based on the time sequence in a set of data is set. Since the user of the display 204 will pay more attention to the continuity of the playback or drawing of a video or animation in the middle period of time, the user is more likely to pay attention to the change in the display duration of the image corresponding to the first segment of data, which can improve the user experience. In addition, the present application may not be limited to this. For example, k may also be equal to n, that is, the display duration of the image corresponding to the last segment of data based on the time sequence in a set of data is set, which can also improve the user experience.

[0056] In addition, in operations 101 and 102 of the present application, the predetermined time period may refer to a time period for the receiving end 202 to receive a set of data, or a time period for receiving two or more sets of data, or a time period for receiving F sets of data, where F is an integer greater than zero or a non-integer.

[0057] In the following description, an example is given in which k is 1 and the predetermined time period is a time period in which the receiving end 202 receives a group of data. This description is applicable to other situations.

[0058] In at least one embodiment, specific implementations of operation 101 and operation 102 differ according to conditions of data received by the receiving end 202 .

[0059] Figure 4 This is a diagram of Operation 101. Figure 5 is a schematic diagram of operation 102 .

[0060] In at least one example, if the receiving end 202 does not receive data at at least one predetermined time within or before the predetermined time period, it is determined that the time interval for receiving data (or the frequency of receiving data) at the receiving end 202 fluctuates, and thus, operation 101 may include the following steps: Figure 4 The operation shown.

[0061] The predetermined time may be a time predetermined by the receiving end 202 to receive data, for example, a time set according to a protocol between the receiving end 202 and the sending end 201 at which the receiving end 202 can receive data.

[0062] In at least one example, if the receiving end 202 does not receive data at Q1 (for example, Q1 is a natural number) predetermined moments within the time length corresponding to receiving a set of data, then it is determined that the frequency of receiving data fluctuates; otherwise, it is determined that the frequency of receiving data does not fluctuate.

[0063] In at least another example, if the receiving end 202 receives data at Q2 (for example, Q2 is a natural number) predetermined moments within the time length corresponding to receiving a set of data, then it is determined that the frequency of receiving data has not fluctuated; otherwise, it is determined that the frequency of receiving data has fluctuated.

[0064] like Figure 4 As shown, operation 101 may include the following operations:

[0065] Operation 1011: Calculate the receiving time interval X of multiple pairs of adjacent segment data received by the receiving end 202 within a predetermined time period. k For example, for the data received in the predetermined time period, calculate X1, X2, ..., X n ;

[0066] Operation 1012: Calculate each receiving time interval X k The scheduled time interval T for sending data with the sender s The difference Y k For example, for the data received in the predetermined time period, according to Y k =X k -Ts, calculate n difference values ​​Y k , that is, Y1, Y2, ..., Y n ;as well as

[0067] Operation 1013: n difference values ​​Y k The absolute value of the largest absolute value difference |Y max |As the change information of the time interval for receiving data within the predetermined time period.

[0068] In at least one example, Figure 5 As shown, operation 102 may include the following operations:

[0069] Operation 1021: Set the updated buffer duration buffer according to the above change information m ;as well as

[0070] Operation 1022: Add the updated buffer duration to the scheduled duration. m , minus the buffer duration before the update m-1 , get the display time T m The display duration is the display duration of the image corresponding to the kth data segment based on the time sequence in a group of data received by the receiving end 202 after the predetermined time period.

[0071] Among them, in operation 1021: the updated buffer duration buffer m Can be equal to change information |Y max |The value of, that is, buffer m＝ |Y max |; or, the updated buffer duration buffer m Can be equal to change information |Y max | plus the time it takes for the display 204 used to display the image to display one frame of the image (i.e., 1fpsTime), that is, buffer m＝ |Y max |+1fpsTime, thus, updating the buffer duration by 1fpsTime can accommodate the image discontinuity caused by the display frame rate.

[0072] In addition, in operation 1021, the value may be divided by a predetermined value, rounded up, and then multiplied by the predetermined value, thereby increasing the buffer m Precision, the predetermined value can be 10 or 100 or other values. For example, after the above processing, the updated buffer length buffer m can be expressed as: or,

[0073] It should be noted that, when the operation 1021 is performed for the first time after the initial buffering time buffer0 is set, the buffering time buffer before updating m-1 Equal to the initial buffer length buffer0.

[0074] In operation 1022, the predetermined duration includes: a first predetermined duration, or a second predetermined duration, or the sum of the first predetermined duration and the second predetermined duration. The first predetermined duration is the predetermined display duration of an image corresponding to a segment of data, that is, the aforementioned predetermined display duration T. The second predetermined duration is the predetermined display duration T of an image corresponding to each segment of data in a group of data received by the receiving end 202 and the actual display duration (that is, the aforementioned t1, ..., t n ), that is, the above △A = T-t1 + T-t2 + T-t3 + ... + Tt n, that is, the second predetermined time length is the aforementioned accumulated deviation ΔA.

[0075] In a specific embodiment, when the predetermined time length is equal to the sum of the first predetermined time length T and the second predetermined time length ΔA, the display time length T calculated in operation 1022 is m It can be expressed as the following formula (1):

[0076] T m =T+ buffer m - buffer m-1 +△A (1)

[0077] In at least one example, when it is determined that the time interval (or the frequency of receiving data) at the receiving end 202 fluctuates, T is calculated based on formula (1). m , due to buffer m The value is greater than buffer m-1 , so the display duration is T m is increased, thereby, by extending the display duration of the image corresponding to the kth (for example, the first) data to digest the change in the time interval for receiving data, thereby ensuring the display continuity of the entire group of images.

[0078] Figure 6 This is another diagram of Operation 101. Figure 7 is another schematic diagram of operation 102 .

[0079] In at least one other example, within or before the predetermined time period, if the receiving end 202 receives data from the transmitting end 201 at multiple predetermined moments within a first predetermined time period (for example, the first predetermined time may be greater than the aforementioned predetermined time period), it is determined that the time interval for receiving data (or the frequency of receiving data) at the receiving end 202 fluctuates slightly or does not fluctuate. Thus, Figure 6 As shown, operation 101 may include the following operations:

[0080] Operation 1011: Calculate the receiving time interval X of multiple pairs of adjacent segment data received by the receiving end 202 within a predetermined time period. k For example, for the data received in the predetermined time period, calculate X1, X2, ..., X n ;

[0081] Operation 1012: Calculate each receiving time interval X k The scheduled time interval T for sending data with the sender s The difference Y k For example, for the data received in the predetermined time period, according to Y k =Xk -Ts, calculate n difference values ​​Y k , that is, Y1, Y2, ..., Y n ;as well as

[0082] Operation 1013a: multiple (eg, n) difference values ​​Y k The average of the absolute values ​​of As the change information of the time interval for receiving data within the predetermined time period.

[0083] For example, in operation 1013a, for the data received in the predetermined time period, n difference values ​​Y k The average of the absolute values ​​of is represented as

[0084] In addition, regarding Figure 6 For instructions on operations 1011 and 1012, refer to Figure 4 In addition, the first predetermined time period may be a time period during which the receiving end 202 receives one group of data or two or more groups of data. For example, the first predetermined time period is a time period during which the receiving end 202 receives three groups of data. The specific length of the first predetermined time period may be set by the user.

[0085] In at least one other example, Figure 7 As shown, operation 102 may include the following operations:

[0086] Operation 1021a: Set the updated buffer duration buffer according to the above change information m ;as well as

[0087] Operation 1022a: Add the updated buffer duration to the scheduled duration. m , minus the buffer duration before the update m-1 , get the display time T m The display duration is the display duration of the image corresponding to the kth data segment based on the time sequence in a group of data received by the receiving end 202 after the predetermined time period.

[0088] Among them, in operation 1021a, the change information is Updated buffer duration buffer m Can be equal to change information The value of Or, the updated buffer duration buffer m Can be equal to change information The value of plus the time for the display 204 used to display the image to display 1 frame of image (i.e., 1fpsTime), that is, Therefore, updating the buffer duration by 1fpsTime can accommodate image discontinuities caused by the display frame rate.

[0089] In addition, in operation 1021a, the value may be divided by a predetermined value, rounded up, and then multiplied by the predetermined value, thereby increasing the buffer m Precision, the predetermined value can be 10 or 100 or other values. For example, after the above processing, the updated buffer length buffer m can be expressed as: or,

[0090] In operation 1022a, the predetermined duration includes: a first predetermined duration, or a second predetermined duration, or the sum of the first predetermined duration and the second predetermined duration. The first predetermined duration is the predetermined display duration of an image corresponding to a segment of data, that is, the aforementioned predetermined display duration T. The second predetermined duration is the predetermined display duration T of an image corresponding to each segment of data in a group of data received by the receiving end 202 and the actual display duration (that is, the aforementioned t1, ..., t n ), that is, the above △A = T-t1 + T-t2 + T-t3 + ... + Tt n , that is, the second predetermined time length is the aforementioned accumulated deviation ΔA.

[0091] In a specific embodiment, when the predetermined time length is equal to the sum of the first predetermined time length T and the second predetermined time length ΔA, the display time length T calculated in operation 1022a is m It may be the same as the above formula (1).

[0092] In at least one other example, when it is determined that the time interval (or the frequency of receiving data) of the receiving end 202 for receiving data fluctuates slightly or does not fluctuate, T is calculated based on formula (1). m At this time, due to the buffer m-1 The value is greater than or equal to buffer m , so the display duration is T m is shortened, thereby improving the timeliness of image display while ensuring the display continuity of the entire set of images.

[0093] In addition, in at least one other example, if the updated buffer duration buffer m Less than or equal to the initial buffer duration buffer0 (for example, buffer0 is 100ms), that is, buffer m ≤buffer0, the display time T is no longer calculated based on formula (2) m, but will display the duration T m Set to the predetermined display time (or the first predetermined time) T, thereby setting the buffer time buffer m The minimum value of the display duration T can be set m In addition, in the buffer m ≤buffer0, the display duration T can also be calculated m The parameters involved in the process are reset or cleared, thus saving storage resources.

[0094] The method for improving image display stability of the present application is described below with reference to an example.

[0095] Figure 8 This is a schematic diagram of the processing flow of this example. Figure 8 As shown, the processing flow includes:

[0099] Operation 804: Calculate the absolute value |Y according to the data received by the receiving end 202 within the predetermined time period max | As the change information of the time interval for receiving data within the predetermined time period, for example, using Figure 4 The operations 1011, 1012 and 1013 shown calculate the absolute value |Y max |;

[0103] Operation 808: Determine buffer m Is it less than or equal to the initial buffer duration buffer0 (i.e., whether buffer m ≤buffer0), if "yes", proceed to operation 809, otherwise proceed to operation 810; when implementing operation 808, the value of buffer can be compared with buffer0. If buffer has been updated, the value of buffer is buffer m , if buffer has not been updated, the value of buffer remains as the initial value buffer0;

At this time, the display time of the image is T. m , where T m It can be the display time T set based on the most recent operation 806. m (That is, the display time length T set when the previous determination that the time interval for receiving data fluctuates) m ); in addition, if the time interval for receiving data does not fluctuate, then the display duration of the image in operation 813 is the predetermined display duration (or, the first predetermined duration) T.

[0109] The above operations 801 to 813 can be performed repeatedly.
