Detailed Description
The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings, not all of them.
Example one
Fig. 1 is a flowchart of an image display parameter adjusting method according to an embodiment of the present invention. The method and the device for adjusting the image display parameters are applicable to the situation of determining the image display parameters of the image to be adjusted on the intelligent terminal, and are particularly suitable for the situation of determining the image display parameters of the image to be adjusted on the intelligent terminal with the touch screen function. The method can be executed by the image parameter adjusting device provided by the embodiment of the invention, the device can be realized by software and/or hardware, and the device can be integrated on various user terminals or servers. Referring to fig. 1, the method of the embodiment of the present invention specifically includes the following steps:
s110, receiving control operation acting on at least one functional area in a preset image adjusting icon, wherein the image adjusting icon is displayed in a current display interface.
The icon may be any icon in a current display interface of the intelligent terminal, and the preset image adjusting icon is an icon that can be used for adjusting an image display parameter in the icons, where the image display parameter may be a color tone, a brightness, a contrast, a Window Width (Window Width), a Window Level (Window Level), and the like. Of course, it can be understood by those skilled in the art that the image adjustment icon may be an icon directly displayed in the current display interface, or may be an icon that can be displayed after receiving a corresponding trigger instruction. In this embodiment, the image adjustment icon may be displayed in the image display area.
The control operation may be an operation acting on a current display interface of the intelligent terminal, and for example, the control operation may be divided into a mouse control operation, a touch operation, a somatosensory remote control operation, and the like according to an input mode; the method can be divided into click operation, sliding operation, pressing operation or a combination of any of the operations according to the execution type; it may also be divided into a single operation, a plurality of operations, a continuous operation, etc. in terms of the number of executions. In addition, at least one functional region in the preset image adjustment icon may be a mode region, a selection region, a scale region, a parameter identification region, and the like. Different parameter adjustment functions can be implemented when the same control operation acts on different functional areas.
Therefore, when a control operation of a user on at least one function area in the preset image adjusting icon is received, the functions corresponding to the control operation and the function area can be realized. The implementation manner of receiving the control operation can be determined by any prior art, and is not described herein again.
And S120, determining image display parameters of the image to be adjusted in the current display interface according to the current function area corresponding to the control operation.
The image to be adjusted may be one image of at least one image in the current display interface, such as a medical image, a human face image, a landscape image, and the like. The image display parameters of the image to be adjusted may be adjustable, and the image display parameters to be adjusted may be brightness, contrast, Window Width (Window Width), Window Level (Window Level), and the like.
Then, the method for determining the image to be adjusted may be determined according to the corresponding relationship between the preset image adjustment icon matched with the control operation and each image in the current display interface; the adjustment can also be determined according to the control operation acting on the preset image to be adjusted in the current display interface. Further, according to the input mode, execution type, execution times, action position and the like of the control operation acting on the image adjusting icon and the current function area corresponding to the control operation, the image display parameters matched with the image to be adjusted can be determined.
Optionally, when the control operation includes a sliding operation, the window width and/or the window level of the image to be adjusted in the current display interface may be directly determined according to the sliding direction of the sliding operation corresponding to the current functional region. For example, the window width and/or window level may be adjusted incrementally or incrementally depending on the particular direction of the sliding operation.
And S130, adjusting the image to be adjusted according to the image display parameters.
The image to be adjusted can be adjusted based on the image display parameters, and illustratively, the display effect of the medical image can be adjusted based on Window Width (Window Width), Window Level (Window Level), contrast, brightness, and the like.
In order to better understand the specific implementation process of the above steps, the following describes an exemplary method for adjusting image display parameters according to this embodiment with reference to a specific example. The exemplary illustration is described from the perspective of user operation and the perspective of intelligent terminal response, respectively, for the same application scenario.
Illustratively, the description from the user operation perspective may be: the current display interface of the intelligent terminal may have at least one Computed Tomography (CT) image, and different images may be used to display structures of different parts of the body, such as skull, lung, liver, soft tissue, and the like, and may also be used to display images of different slices of the same part of the body, such as cross-sectional images, coronal images, and sagittal images. Taking 3 tomographic images of the skull in the current display interface as an example, then, in order to clearly display the structure to be observed in each image, the user can adjust the window width and window level display parameters related to each image to realize the purpose. The method for adjusting the parameters can be as follows:
if the image adjustment icon matched with the window width and the window level parameter is not displayed in the current display interface or is displayed but not in an applicable state, the icon can be made applicable through any trigger operation, for example, clicking a trigger button or inputting a shortcut key. Of course, if the icon is directly in the applicable state, the above-mentioned trigger operation need not be executed. Of course, it is understood that the image adjustment icons matched with the window width and the window level may be one, two or more. The exemplary description takes an image adjustment icon as an example, that is, the window width and the window level can be adjusted simultaneously by one icon.
Further, if each image has an image adjusting icon matched with the image adjusting icon for adjusting the window width and the window level, the user can determine the image to be adjusted and the image display parameters by respectively controlling each image adjusting icon; if each image is matched with an image adjusting icon for adjusting the window width and the window level, the user can directly control the image adjusting icon to determine the image display parameters of each image to be adjusted. The control operation applied to the image adjustment icon may be a click operation, a slide operation, a press operation, or a combination of any operations. The user can control the image adjustment icon multiple times based on the above steps until the requirement is met.
Then, the response angle of the smart terminal corresponding to the user operation may be: if the intelligent terminal receives an instruction for triggering an image adjusting icon for adjusting the window width and the window level, activating the image adjusting icon; and if the control operation acting on the image adjusting icon is received, determining the image to be adjusted matched with the current display interface and the image display parameter acting on the image to be adjusted according to the control operation, and adjusting the image to be adjusted according to the image display parameter. Of course, it is understood that the adjusted image display parameters may also be associated with other devices, for example, in the field of radiotherapy, the image display parameters for radiotherapy may be communicated with a radiotherapy system, a radiotherapy machine, etc.
According to the technical scheme of the embodiment of the invention, the control operation acting on at least one functional area in the preset image adjusting icon is received, so that the control operation can be distinguished from the conventional gesture operation directly acting on the image to be adjusted; and determining image display parameters of the image to be adjusted in the current display interface according to the current functional area corresponding to the control operation, and adjusting the image to be adjusted according to the image display parameters, so that the image display parameters can be adjusted in a diversified manner based on different control operations. According to the technical scheme, the image display parameters can be flexibly adjusted based on the preset image adjusting icons, so that functions of browsing and zooming images and image display parameter adjusting functions can be flexibly applied, and confusion and conflict of functions are avoided.
An optional technical solution, in the method for adjusting image display parameters, may further include: when the instruction corresponding to the control operation is a switching instruction, switching the display mode of the image adjusting icon, wherein the display mode can comprise a moving mode and a fixed mode. The image adjusting icon in the moving mode can move, so that a user can move the icon to any position, and the problem that the browsing of the image is influenced when the icon is fixed at the set position is avoided; the image adjustment icon in the fixed mode may be kept fixed to facilitate adjustment of the image display parameter according to the control operation, avoiding a possibility that the control operation for adjusting the image display parameter and the operation for moving the image adjustment icon are mixed up. The step setting has the advantage that the display mode of the image adjusting icon can be switched according to the requirement of a user, so that the browsing of the image and the adjustment of the image display parameters are not interfered with each other.
Illustratively, the image adjustment icon is exemplified by a circular button as shown in fig. 2A, which expands from the center and may include a mode area 1 and a selection area 2. When the image adjustment icon is in the fixed mode, when a control operation acts on the mode area 1, the mode area 1 may be changed, for example, the mode area 1 may be moved toward the direction in which the slide operation slides, as shown in fig. 2B. Alternatively, when a control operation is applied to the mode area 1, the adjustment direction of the current image display parameter may also be indicated by setting an arrow, as shown in fig. 2C.
When a switching instruction for display mode switching is received, for example, when the mode area 1 is clicked, switching between the moving mode and the fixed mode can be realized. The mode areas 1 in different modes may have different representation forms, such as different colors, etc., in order to distinguish the display modes.
Before specifying the specific meanings of the various embodiments described below, an understanding of "end point", "start point", "coordinates of end point" and "coordinates of start point" is set forth herein:
wherein, the starting point and the ending point can be understood as: when the control operation is a sliding operation, the first action point of the sliding operation may be regarded as a start point, and the last action point may be regarded as an end point, or of course, the center point of the image adjustment icon may be directly regarded as a start point, and the last action point may be regarded as an end point; when the control operation is single click operation, the central point of the image adjusting icon can be used as a starting point, and the action point of the single click operation can be used as an end point; when the control operation is a two-click operation, the action point of the first click operation may be taken as a start point, and the action point of the second click operation may be taken as an end point.
Wherein the coordinates of the start point and the coordinates of the end point may be based on coordinates in the following X-Y coordinate system: illustratively, a coordinate system is established with the center point of the image adjustment icon as an origin, the lateral direction as an X-axis, the longitudinal direction as a Y-axis, the right and upper directions as positive directions, and the left and lower directions as negative directions. For example, as shown in fig. 2A, a coordinate system is established, with the center point of the pattern area 1 as an origin, the horizontal direction as an X axis, and the longitudinal direction as a Y axis, and coordinate values on the X axis and the Y axis have a corresponding relationship with the number of pixels. Optionally, the user may adjust the corresponding relationship between the coordinate values and the number of pixels, for example, the coordinate values are increased by 1 or decreased by 1 every time a pixel passes through. Wherein the lateral direction may be used to represent the window width and the longitudinal direction may be used to represent the window level.
Example two
The present embodiment is optimized based on the first embodiment. In this embodiment, "determining image adjustment parameters of an image to be adjusted in a current display interface" is specifically optimized to "determining image display parameters of an image to be adjusted in a current display interface based on a preset distance adjustment method; the method for adjusting the distance comprises the following steps of determining image display parameters of an image to be adjusted in a current display interface based on a preset distance adjusting method, wherein the image display parameters comprise: determining a difference value of the coordinates of the end point and the coordinates of the start point corresponding to the control operation in the transverse direction and/or the longitudinal direction; and determining a change value according to the difference value and the set change rate, and obtaining an image display parameter according to the change value and the basic value. "the method of this embodiment may specifically include the following steps:
and receiving a control operation acting on at least one functional area in a preset image adjusting icon, wherein the image adjusting icon is displayed in the current display interface.
Determining a difference value between the coordinates of the end point and the coordinates of the start point corresponding to the control operation in the lateral direction and/or the longitudinal direction. The difference in the lateral direction and/or the longitudinal direction of the control operation may be determined from the coordinates of the end point and the coordinates of the start point of the control operation. Then, the difference in coordinates of the start point and the end point defined in the above-mentioned coordinate system has a positive or negative score. For example, taking the difference in the lateral direction as an example, the difference is a positive number when the end point is right of the start point; otherwise, the difference is negative.
Of course, it can be understood by those skilled in the art that when the image display parameter of the image to be adjusted has a large variation range, for example, the window width and the window level may range from minus thousands to plus thousands, the termination point corresponding to the control operation may be located outside the image adjustment icon, in other words, the termination point may be located inside the selection area 2 or outside the selection area 2.
And determining a change value according to the difference value and the set change rate, and obtaining an image display parameter according to the change value and the basic value. Where the set rate of change may be a change in an image display parameter for a difference in unit coordinates, the change may be a product of the difference and the set rate of change, which may also have a positive or negative score. In addition, the basic value may be a parameter before the current image display parameter adjustment, and the adjusted image display parameter may be the sum of the variation value and the basic value, or may be in other calculation manners.
And adjusting the image to be adjusted according to the image display parameters.
In order to better understand the specific implementation process of the above steps, the following description proceeds to an exemplary description of the image display parameter adjustment method of the present embodiment based on the above specific example.
As shown in fig. 2D, the image display parameter adjustment method is described with a slide control operation as an example on the basis of the above-described buttons: the pattern area 1 is controlled and slid toward the lower right, the coordinates a (x1, y1) of the start point and the coordinates B (x2, y2) of the end point can be determined according to the sliding operation, and further the image display parameters can be adjusted based on the number of pixels moved in the lateral direction and the longitudinal direction by the sliding operation, respectively. Illustratively, when the sliding operation moves 20 pixels in the horizontal direction in the positive direction and moves 60 pixels in the vertical direction in the negative direction, the set change rate is 2, the window width basic value is 1400, and the window level basic value is 400, then the adjusted window width value is 1400+20 × 2 or 1440, and the adjusted window level value is 400-60 × 2 or 280.
According to the technical scheme of the embodiment of the invention, the change value of the image display parameter can be determined according to the difference value of the control operation in the transverse direction and/or the longitudinal direction and the set change rate, and the adjusted image display parameter can be further determined by combining with the basic value, so that the operation is convenient and the observability is strong.

In this embodiment, "determining image adjustment parameters of an image to be adjusted in a current display interface" is specifically optimized to "determining image display parameters of an image to be adjusted in a current display interface based on a preset angle adjustment method; the method for determining the image display parameters of the image to be adjusted in the current display interface based on the preset angle adjusting method comprises the following steps: determining an included angle between a straight line formed based on the starting point and the ending point and the transverse direction and/or the longitudinal direction according to the coordinates of the starting point and the coordinates of the ending point corresponding to the control operation; and determining a change value according to the included angle and the set change rate, and obtaining an image display parameter according to the change value and the basic value. "the method of this embodiment may comprise the steps of:
and receiving a control operation acting on at least one functional area in a preset image adjusting icon, wherein the image adjusting icon is displayed in the current display interface.
And determining an included angle between a straight line formed based on the starting point and the end point and the transverse direction and/or the longitudinal direction according to the coordinates of the starting point and the coordinates of the end point corresponding to the control operation.

Furthermore, the angles of the different quadrants defined in the above coordinate system may have positive and negative components. For example, as shown in fig. 2D, the angle from the positive direction of the X-axis is positive, and the angle from the negative direction of the X-axis is negative; similarly, the included angle between the Y-axis positive direction and the Y-axis negative direction is positive, and the included angle between the Y-axis negative direction and the Y-axis positive direction is negative. The coordinate system in the above exemplary illustration may divide the image adjustment icon into four different quadrants, and from the upper right corner, the counterclockwise rotation may be divided into a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant, respectively. Then, taking the fourth quadrant as an example, the angle between the straight line AB in the fourth quadrant and the transverse direction is positive, and the angle between the straight line AB and the longitudinal direction is negative.

In addition, the basic value may be a parameter before the current image display parameter adjustment, and the adjusted image display parameter may be the sum of the variation value and the basic value, or may be in other calculation manners. The angle, the set rate of change, and the like may have other meanings.
Then, in the second embodiment, the determination of the image display parameters of the image to be adjusted in the current display interface based on the preset distance adjustment method is described in detail, and in the third embodiment, the determination of the image display parameters of the image to be adjusted in the current display interface based on the preset angle adjustment method is described in detail. However, it is understood that, in an alternative embodiment, it is determined whether the preset distance adjustment method or the preset angle adjustment method is performed according to a received trigger instruction for determining an adjustment method, or whether the preset distance adjustment method, the preset angle adjustment method, or a method of mixing a distance and an angle is performed according to a received trigger instruction for determining an adjustment method (for example, in embodiment four). The step setting has the advantage that a specific adjusting method can be selected according to the requirements of the user so as to better conform to the use habits of the user.
And adjusting the image to be adjusted according to the image display parameters.
According to the technical scheme of the embodiment of the invention, the change value of the image display parameter can be determined according to the included angle of the control operation in the transverse direction and/or the longitudinal direction and the set change rate, further, the adjusted image display parameter can be determined by combining the basic value, the operation is convenient, and the observability is strong.
An optional technical solution, where the change value is determined according to the included angle and the set change rate, may specifically include the following steps:
and acquiring the stay time of the control operation at the end point corresponding to the control operation.
The control operation may be a click operation or a slide operation. The action point of the clicking operation acting on the image adjusting icon can be regarded as a starting point and can also be regarded as an end point; and the first action point of the sliding operation acting on the image adjustment icon may be regarded as a start point and the last action point may be regarded as an end point. And acquiring the stay time of the control operation at the end point corresponding to the control operation, in other words, acquiring the stay time of the click operation at the action point or the stay time of the sliding operation at the end point, so as to determine different change values according to the stay time.

Where the set rate of change may be coordinated with the angle when the angle may be used to represent the frequency of change of the image display parameter, illustratively, when the set rate of change is 2 and the angle is-30 deg., it may be considered that the change value is-2 every 30 milliseconds. Further, according to the stay time of the control operation at the termination point corresponding to the control operation, the change value of the image display parameter can be calculated. The adjusted image display parameter may then be the sum of the variation value and the basic value, but may also be calculated in other ways. The scheme has the advantages that the adjusted image display parameters are determined according to the stay time, and the diversity of image adjustment is increased.
For example, as shown in fig. 2D, when determining the image display parameters of the image to be adjusted in the current display interface based on the preset angle adjustment method, the image display parameters may be adjusted based on the angles of the sliding operation with the transverse direction and the longitudinal direction, respectively. For example, when the straight line formed by the start point a (x1, y1) and the end point B (x2, y2) makes an angle of 60 ° with the transverse direction, makes an angle of-30 ° with the longitudinal direction, and the set rate of change is 2, the window width may be considered to be changed by 2 every 60 milliseconds, the window level may be considered to be changed by-2 every 30 milliseconds, and when the dwell time is 1.2 seconds, the window width basic value is 1400, and the window level basic value is 400, the adjusted window width is 1400+ (1200/60) < 2 > 1440, and the adjusted window level is 400- (1200/30) < 2 > 320.
