Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. Thus, the various sequences in the specification and drawings are for the purpose of describing certain embodiments only and are not intended to imply a required sequence unless otherwise indicated where such sequence must be followed.
The numbering of the components as such, e.g., "first", "second", etc., is used herein only to distinguish the objects as described, and does not have any sequential or technical meaning. The term "connected" and "coupled" when used in this application, unless otherwise indicated, includes both direct and indirect connections (couplings).
The ultrasound imaging apparatus provided by the present application, as shown in fig. 1, includes an ultrasound probe 30, a transmission/reception control circuit 40, a beam synthesis module 50, an IQ demodulation module 60, a processor 20, a human-computer interaction device 70, and a memory 80.
The ultrasonic probe 30 includes a transducer (not shown) composed of a plurality of array elements arranged in an array, the plurality of array elements are arranged in a row to form a linear array, or are arranged in a two-dimensional matrix to form an area array, and the plurality of array elements may also form a convex array. The array elements are used for emitting ultrasonic beams according to the excitation electric signals or converting the received ultrasonic beams into electric signals. Each array element can be used for realizing the mutual conversion of the electric pulse signal and the ultrasonic beam, thereby realizing the transmission of ultrasonic waves to the detected target tissue (such as an interested area in the biological tissue of organs, tissues, blood vessels, fetuses and the like in a human body or an animal body) and also being used for receiving the echo of the ultrasonic waves reflected back by the tissue. In performing ultrasonic detection, which array elements are used for transmitting ultrasonic beams and which array elements are used for receiving ultrasonic beams, or the array elements are controlled to be time-slotted for transmitting ultrasonic beams or receiving echoes of ultrasonic beams by the transmission control circuit 410 and the receiving control circuit 420. The array elements participating in ultrasonic wave transmission can be simultaneously excited by the electric signals, so that the ultrasonic waves are transmitted simultaneously; or the array elements participating in the ultrasonic wave transmission can be excited by a plurality of electric signals with certain time intervals, so that the ultrasonic waves with certain time intervals are continuously transmitted.
The user selects a suitable position and angle by moving the ultrasonic probe 30 to transmit ultrasonic waves to the tissue X to be measured and receive echoes of the ultrasonic waves returned by the tissue X to be measured, and outputs ultrasonic echo signals, which are channel analog electric signals formed by using the receiving array elements as channels and carry amplitude information, frequency information and time information.
The transmit control circuit 410 is configured to generate a transmit sequence according to the control of the processor 20, the transmit sequence being configured to control some or all of the plurality of array elements to transmit ultrasonic waves to the target tissue, and the transmit sequence parameters include the position of the array element for transmission, the number of array elements, and ultrasonic beam transmission parameters (e.g., amplitude, frequency, number of transmissions, transmission interval, transmission angle, wave pattern, focusing position, etc.). In some cases, the transmit control circuitry 410 is further configured to phase delay the transmitted beams to cause different transmit elements to transmit ultrasound at different times so that each transmitted ultrasound beam can be focused at a predetermined region of interest. In different operation modes, such as a B image mode, a C image mode, and a D image mode (doppler mode), the parameters of the transmit sequence may be different, and the echo signals received by the receive control circuit 420 and processed by the subsequent modules and corresponding algorithms may generate a B image reflecting the tissue anatomy, a C image reflecting the tissue anatomy and blood flow information, and a D image reflecting the doppler spectrum image.
The receiving control circuit 420 is configured to receive the ultrasonic echo signal from the ultrasonic probe and process the ultrasonic echo signal. The receive control circuit 420 may include one or more amplifiers, analog-to-digital converters (ADCs), and the like. The amplifier is used for amplifying the received echo signal after proper gain compensation, the amplifier is used for sampling the analog echo signal according to a preset time interval so as to convert the analog echo signal into a digitized signal, and the digitized echo signal still retains amplitude information, frequency information and phase information. The data output by the receive control circuit 420 may be output to the beamforming module 50 for processing or to the memory 80 for storage.
The beam forming module 50 is connected to the receive control circuit 420 through signals, and is configured to perform beam forming processing such as corresponding delay and weighted summation on the echo signal, because distances from the ultrasonic receiving point in the measured tissue to the receiving array elements are different, channel data of the same receiving point output by different receiving array elements have delay differences, delay processing is required, phases are aligned, and weighted summation is performed on different channel data of the same receiving point, so as to obtain ultrasonic image data after beam forming, where the ultrasonic image data output by the beam forming module 50 is also referred to as radio frequency data (RF data). The beam synthesis module 50 outputs the radio frequency data to the IQ demodulation module 60. In some embodiments, the beam forming module 50 may also output the rf data to the memory 80 for buffering or saving, or directly output the rf data to the processor 20 for image processing.
Beamforming module 50 may perform the above functions in hardware, firmware, or software, for example, beamforming module 50 may include a central controller Circuit (CPU), one or more microprocessor chips, or any other electronic components capable of processing input data according to specific logic instructions, which when implemented in software, may execute instructions stored on a tangible and non-transitory computer readable medium (e.g., memory) to perform beamforming calculations using any suitable beamforming method.
The IQ demodulation module 60 removes the signal carrier by IQ demodulation, extracts the tissue structure information included in the signal, and performs filtering to remove noise, and the signal obtained at this time is referred to as a baseband signal (IQ data pair). The IQ demodulation module 60 outputs the IQ data pair to the processor 20 for image processing.
In some embodiments, the IQ demodulation module 60 further buffers or saves the IQ data pair output to the memory 80, so that the processor 20 reads the data from the memory 80 for subsequent image processing.
The IQ demodulation module 60 may also perform the above functions in hardware, firmware or software, and in some embodiments, the IQ demodulation module 60 may also be integrated with the beam synthesis module 50 in a single chip.
The processor 20 is used for a central controller Circuit (CPU), one or more microprocessors, a graphics controller circuit (GPU) or any other electronic components configured to process input data according to specific logic instructions, and may control peripheral electronic components according to the input instructions or predetermined instructions, or perform data reading and/or saving on the memory 80, or may process input data by executing programs in the memory 80, such as performing one or more processing operations on acquired ultrasound data according to one or more working modes, the processing operations including, but not limited to, adjusting or defining the form of ultrasound waves emitted by the ultrasound probe 30, generating various image frames for display by a display of the subsequent human-computer interaction device 70, or adjusting or defining the content and form of display on the display, or adjusting one or more image display settings (e.g., ultrasound images, graphics processing data, etc.) displayed on the display, Interface components, locating regions of interest).
The acquired ultrasound data may be processed by the processor 20 in real time during a scan or treatment as echo signals are received, or may be temporarily stored on the memory 80 and processed in near real time in an online or offline operation.
In this embodiment, the processor 20 controls the operations of the transmission control circuit 410 and the reception control circuit 420, for example, controls the transmission control circuit 410 and the reception control circuit 420 to operate alternately or simultaneously. The processor 20 may also determine an appropriate operation mode according to the selection of the user or the setting of the program, form a transmission sequence corresponding to the current operation mode, and send the transmission sequence to the transmission control circuit 410, so that the transmission control circuit 410 controls the ultrasound probe 30 to transmit the ultrasound wave using the appropriate transmission sequence.
The processor 20 is also operative to process the ultrasound data to generate a gray scale image of the signal intensity variations over the scan range, which reflects the anatomical structure inside the tissue, referred to as a B-image. The processor 20 may output the B image to a display of the human-computer interaction device 70 for display.
The human-computer interaction device 70 is used for human-computer interaction and comprises an input device and a display. The display is used for outputting visual information. The input device is used for receiving input of a user.
The existing ultrasonic imaging devices have more and more functions, and a considerable number of scenes need to be switched in function, for example, in the ultrasonic scanning, the image modes are as follows: b image mode, C image mode, D image mode (doppler mode), etc., and a doctor needs to select a desired image mode among these image modes for an ultrasound scan. For another example, after scanning to obtain an ultrasound image, measurement needs to be performed in multiple ways, and a doctor may need to perform measurement in one way and then perform measurement in another way, which also needs to switch the measurement ways frequently. Therefore, the input device is required to be capable of providing not only the operation of switching the function to the user but also various input operations to the user under each function. In the present invention, the input device is used for receiving an input from a user, and includes at least a trackball (710 in fig. 2 and 3) or a touchpad (720 in fig. 4 and 5), and further, the input device may further include a touch screen disposed on the display, in other words, the display is a touch display. The functions of the trackball and the touch pad are basically the same, one of the ultrasonic imaging devices is used as a part of the input device, and the trackball 710 is mainly taken as an example in the following embodiments for description.
Further, as shown in fig. 6, the method for controlling the ultrasonic imaging device to switch functions by the processor 20 includes the following steps:
step 1, the processor 20 displays the ultrasound image on the display interface of the display, and simultaneously displays the function prompt bar, which is shown in fig. 7. The function prompt bar displays at least two function icons, such as a first function icon and a second function icon. Wherein each function icon corresponds to a function of the trackball or the touch pad, respectively. Three function icons are shown in fig. 7. The function icons are arranged in a preset order, and the function icons arranged in the preset order form an icon bar 751. The function and the function icon are in a mapping relation, and the arrangement sequence of the function icons is basically the switching sequence of the function. In this embodiment, the function prompt bar is displayed in a lower central position of the ultrasound image, so as to avoid influencing the user to focus on the ultrasound image as much as possible.
The function icons displayed by the function prompt bar at the same time can be all function icons with switchable functions, so that the switching is convenient for users; the function icons displayed by the function prompt bar at the same time can also be part of all the function icons with switchable functions, so that the space occupied by the display interface is saved; the present embodiment will be described with reference to the latter example. For example, there are 5 functions that can be switched, that is, the function prompt bar can display 5 function icons, only 3 of the function icons are simultaneously displayed in the icon bar 751 in fig. 7, and with the function switching, one function icon that is not displayed before is displayed, and the corresponding one displayed function icon is hidden.
The arrangement order of the function icons can be set according to needs, for example, after initialization, the function icons are arranged according to the use frequency, the higher the frequency is, the higher the use frequency of the function icon is, the icon bar 751 is a bar, the function icon with the highest use frequency is located in the middle of the icon bar 751, the function icons with the second use frequency are respectively located on two sides of the middle function icon, and so on, the arrangement according to the use frequency is realized.
The processor 20 displays the first function icon corresponding to the currently activated function in a differentiated manner on the display interface of the display, taking fig. 7 as an example, where the first function icon corresponding to the currently activated function is C.
The cursor editing function corresponding to the trackball or the touch pad is different under different image modes or different measuring modes of the ultrasonic imaging device, so that the function switching of the invention is not only the cursor editing function corresponding to the trackball or the touch pad, but also the function of the ultrasonic imaging device.
And 2, switching the functions corresponding to the function icons by the processor 20 according to the switching instruction received by the input device. Specifically, the processor 20 closes the function corresponding to the first functional icon and activates the function corresponding to the second functional icon according to the preset sequence according to the first switching instruction received by the input device, cancels the differentiated display of the first functional icon, and differentially displays the second functional icon. Compared with the function icons corresponding to other unactivated functions, the function icons corresponding to the currently activated functions are displayed in a differentiated mode, so that a user can observe the currently activated functions in a striking mode conveniently, and corresponding functions can be executed rapidly through a track ball or a touch pad. A trackball or touchpad is used to perform the activated function. For example, as shown in fig. 7, the currently activated function C, the function of the trackball or the touchpad, is to move the cursor to select a region of interest on the ultrasound image, and to switch to the function B, which corresponds to switching the value of the measurement parameter.
The first switching instruction may be generated by pressing a button of the input device, by scrolling a trackball in a specific direction, by sliding (finger) on a touch pad in a specific direction, or by clicking an icon on a touch screen of the display when the display is a touch display, or the like, and the clicked icon may be an icon for triggering the switching instruction, such as an arrow icon to the left or right, or may be a function icon itself. In this embodiment, the input device further includes a first button a disposed adjacent to the trackball or touch pad.
The switching of the function can be triggered by only one button or two buttons, and the invention is explained by two embodiments respectively.
In the first embodiment, only the first button a is used to switch the function, and the first button a is used to trigger the first switching instruction. The icon bars 751 may be arranged side-to-side as shown in fig. 7. The switching of the function icons (corresponding to the switching of the functions) is performed according to the arrangement sequence of the function icons, since the switching is performed only by the first switching instruction in this embodiment, the function icons are switched to the left or right in general, and when the functions are continuously switched in one direction (for example, the left side) of the function prompt bar, the corresponding function icons are displayed in a loop. For example, there are A, B, C, D, E five function icons, the arrangement order of the function icons is the order of ABCDE, the icon bar 751 displays three function icons B, C, D after initialization, when the currently activated function is B, the B icon is differentially displayed (as shown in fig. 8), when the first button a is pressed, the function corresponding to the B icon is closed and the function corresponding to the a icon is activated, the differential display of the B icon is cancelled, and the icon bar 751 displays A, B, C three function icons, and the a icon is differentially displayed; if the first button a is pressed again, similarly, according to the sequence of arrangement of the function icons (the next function of the a icon is the E icon), the currently activated function a is closed and the next function of the function is activated, that is, the function a is closed, the function E is activated, the a icon is not displayed differently, the icon bar 751 displays C, D, E three function icons and the icon E is displayed differently, so that not only can the function switching be visualized, but also the function cyclic switching (the function and the function icon are in a corresponding relationship, that is, the cyclic switching of the function icons on the display interface) is realized.
The icon bar 751 is provided with a first identifier 752 at a first end thereof, and the first identifier 752 is used to prompt the user that the next function to be switched is a function corresponding to a function icon adjacent to the currently differentially displayed function icon and close to the first end. The first indicator 752 may be an icon for prompting the function to switch the direction, such as an arrow in fig. 7, or may be a character indicator, such as B in fig. 10, where the character may be an abbreviation of the name of the function. If a touch screen is used to generate a switching command, a first switching command may be triggered by clicking on the first identifier 752.
In a second embodiment, the method further includes step 3: the processor 20 closes the function corresponding to the first functional icon and activates the function corresponding to the third functional icon according to the preset sequence according to the second switching instruction received by the input device, cancels the differential display of the first functional icon, and differentially displays the third functional icon. And the user operation corresponding to the generation of the first switching instruction is different from the user operation corresponding to the generation of the second switching instruction. Namely, the user can switch the function by at least two operation modes, which is very convenient. The second switching instruction may be generated by pressing a button of the input device, by scrolling a trackball in a specific direction, by sliding (finger) on a touch pad in a specific direction, or by clicking an icon on a touch screen of the display when the display is a touch display, or the like, and the clicked icon may be an icon for triggering the switching instruction, such as an arrow icon to the left or right, or a function icon itself. In this embodiment, as shown in fig. 2 to 4, the input device includes not only the first button a but also the second button b, and the functions are switched by the buttons a and b. The second button b is used for triggering a second switching instruction. The second button b is disposed adjacent to the trackball or touch pad. That is, when the second button b is pressed, the function corresponding to the first function icon is closed and the function corresponding to the third function icon is activated according to the sequence of the arrangement of the function icons, and the differential display of the first function icon is cancelled and the third function icon is differentially displayed.
In this embodiment, there are two ways to switch functions, which are described below.
In a first mode, although the first button a and the second button b are two buttons, the switching direction of the function is the same when the first button a is pressed and the second button b is pressed, that is, the second function icon and the third function icon are both the function icons adjacent to the first function icon and near the first end of the icon bar 751. In this way, the second function icon and the third function icon may be the same icon and correspond to the same function. For example, the currently activated function is C (C is considered to be the first function icon), the function prompt bar is shown in fig. 7, pressing the first button a closes the function C, activates the function B (B is considered to be the second function icon), and the function prompt bar changes to fig. 8; since function B is the currently activated function, icon B can be viewed as the first function icon, and pressing the first button a turns off function B, activating function a (a is viewed as the second function icon). When the currently activated function is C (C is regarded as the first function icon), the function prompt bar is shown in fig. 7, and when the second button B is pressed, the function C is closed, the function B is activated (B is regarded as the third function icon), and the function prompt bar changes to fig. 8; since function B is the currently activated function, icon B can be regarded as the first function icon, and pressing the second button B closes function B and activates function a (a is regarded as the third function icon). Of course, the second function icon and the third function icon may be different icons corresponding to different functions. For example, the currently activated function is C (see fig. 7), and when the first button a is pressed, the function C is closed, the function B is activated, and the function prompt bar changes to fig. 8; when the first button a is pressed again, the function B is closed and the function A is activated. When the currently activated function is C, the function prompt bar is shown in FIG. 7, and when the second button b is pressed, the function C is closed, the function A is activated, and when the second button b is pressed, the function A is closed, and the function D is activated. The second switching command corresponds to a jump switch. By the arrangement, the functions can be conveniently switched by the buttons no matter a right-handed user or a left-handed user.
In the case of an adult with open fingers, the distance that the thumb and pinky can span is s; the first button a and the second button b are spaced apart by a distance s, which may be a statistical mean. That is, the first button a and the second button b are spaced apart to allow an adult to operate with one hand, so that the user can perform blind operation. The first button a and the second button b may be symmetrically disposed on the left and right sides of the trackball or the touch pad as shown in fig. 2, or may be disposed on the front and rear sides of the trackball or the touch pad as shown in fig. 3.
As shown in fig. 7, a first identifier 752 is disposed at a first end of the icon bar 751, and the first identifier 752 is used to prompt the user to switch the next function to a function icon adjacent to the currently differentiated displayed function icon and close to the first end. In an alternative embodiment, the second end of the icon bar 751 can also be provided with a first marker 752. The first label 752 may be an icon for prompting a function to switch direction, e.g., the arrow of 752 in FIG. 7 indicates that the next function is function B to the left of the currently active function C; the first identification 752 may also be a character identification, e.g. B in fig. 10 at 752 indicates that the next function is function B to the left of the currently active function C, and the character may be an abbreviation for the name of the function. Similarly, if a touch screen is used to generate a switch command, the first switch command may be triggered by clicking on the first indicator 752.
In the second mode, the switching direction of the functions is opposite to that of the second button b after the first button a is pressed, namely, the second function icon is a function icon adjacent to the first function icon and close to the first end of the icon bar 751, and the third function icon is a function icon adjacent to the first function icon and close to the second end of the icon bar 751. For example, the currently activated function is C (C can be seen as the first function icon), the function hint column is shown in fig. 7, pressing the first button a closes function C, activates function B (B can be seen as the second function icon), the function hint column becomes fig. 8, and due to the now activated function B, function icon B can be seen as the first function icon, and pressing the first button a closes function B, activates function a (a can be seen as the second function icon). When the currently activated function is C (C can be seen as the first function icon), the function prompt bar is seen in fig. 7, and when the second button b is pressed, the function C is closed, the function D is activated (D can be seen as the third function icon), and the function prompt bar changes to fig. 9; due to the function D activated at this time, the function icon D can be regarded as a first function icon, and when the second button b is pressed, the function D is turned off and the function E is activated (E can be regarded as a third function icon). This arrangement facilitates quick switching to a desired function by the user.
The distance and the position of the first button a and the second button b are the same, preferably, the positions of the first button a and the second button b are related to the arrangement of the icons, for example, when the icons are arranged left and right, the first button a and the second button b are respectively positioned on the left side and the right side of the track ball or the touch pad, so that the blind operation of a user can be conveniently realized. For another example, the icons are arranged up and down, and the first button a and the second button b are respectively located on the front side and the rear side of the track ball or the touch pad, as shown in fig. 3 and 5. Of course, the arrangement of the icons on the display interface is not limited to left and right or up and down, and other forms, such as arc, can be adopted.
As shown in fig. 7, a first identifier 752 is disposed at a first end of the icon bar 751, and the first identifier 752 is used to prompt the user to switch the next function to a function icon adjacent to the currently differentiated displayed function icon and close to the first end. A second end of the icon bar 751 is provided with a second identification 754; the second indication 754 is used to prompt the user to switch to a next function that is a function corresponding to a function icon adjacent to the currently differentiated displayed function icon and near the second end. That is, the first 752 and the second 754 identifiers are different. The first label 752 may be an icon for prompting a function to switch direction, e.g., the arrow of 752 in FIG. 7 indicates that the next function is function B to the left of the currently active function C; the first identification 752 may also be a character identification, e.g. B in fig. 10 at 752 indicates that the next function is function B to the left of the currently active function C, and the character may be an abbreviation for the name of the function. The second identifier 754 may be an icon for prompting a function to switch direction, for example, an arrow in 754 in fig. 7 indicates that the next function is the function D to the right of the currently activated function C; the second identifier 754 may also be a character identifier, e.g., D in 754 in fig. 10 indicates that the next function is the function D to the right of the currently activated function C, and the character may be an abbreviation for the name of the function. Therefore, the function of next switching of the user is well prompted by setting the first identifier and the second identifier. If a touch screen is used to generate a switching instruction, the first switching instruction may be triggered by clicking on the first identifier 752 and the second switching instruction may be triggered by clicking on the second identifier 754.
The above description provides various operation modes for switching the functions, and actually, the activated function icons may be displayed differently, for example, the differentiated display of the function icon corresponding to the currently activated function by the processor 20 on the display interface includes: at least one of size differentiation display, color differentiation display, brightness differentiation display, and filler differentiation display. The size is differentiated, for example, the size of the activated function icon is larger than the size of the non-activated function icon. The color differentiation displays, for example, the color of the activated function icon is different from the color of the inactivated function icon, which is more vivid and distinct. The brightness difference is displayed, for example, the background of the whole function prompt bar is dark, such as black, the brightness of each function icon is higher than that of the background, and the brightness of the activated function icon is higher than that of the inactivated function icon. The filler is displayed differently, for example, the activated function icon is filled with the filler to be distinguished from the non-activated function icon. In the present invention, the processor 20 also displays the third identifier 753 corresponding to the currently activated function in the vicinity of, for example, directly below, the function icon, so as to highlight the activated function icon more. In this embodiment, the third flag 753 includes a function character of a currently activated function; as shown in fig. 7, the currently activated function icon is C, and the third flag 753 immediately below it is "C".
As mentioned above, there are various ways of displaying the differential display, and there are also various processes, and the following two examples are used for illustration.
In one embodiment, all switchable function icons are displayed simultaneously in icon bar 751, and all function icons are quiescent. When the function is continuously switched in one direction of the function presentation bar, it is equivalent to cycle through all the functions. For example, B, C and D are all functions that need to be switched, the current function prompt bar is in FIG. 8, the currently activated function is the leftmost function B, and the function is switched to the rightmost function D when the function prompt bar changes to FIG. 9. The processor 20 canceling the differentiated display of the first function icon and the differentiated display of the second function icon includes: hiding the function character corresponding to the first function icon, and displaying the corresponding function character near the second function icon. Likewise, the processor 20 canceling the differentiated display of the first function icon and the differentiated display of the third function icon includes: hiding the function character corresponding to the first function icon, and displaying the corresponding function character near the third function icon.
In one embodiment, only partially switchable function icons are simultaneously displayed in the icon bar 751, that is, the number of function icons displayed in the icon bar 751 is fixed and is less than the total number of function icons. The processor 20 canceling the differentiated display of the first function icon and the differentiated display of the second function icon includes: hiding the function character corresponding to the first function icon, and displaying the corresponding function character near the second function icon. Likewise, the processor 20 canceling the differentiated display of the first function icon and the differentiated display of the third function icon includes: hiding the function character corresponding to the first function icon, and displaying the corresponding function character near the third function icon. If the function icon corresponding to the function needing to be switched by the switching instruction is not in the icon bar 751, the function icon corresponding to the function needing to be switched by the switching instruction needs to be displayed in the icon bar 751, and the function icon on the opposite side of the function icon needs to be hidden, so that the number of the function icons displayed in the icon bar 751 is ensured to be unchanged.
In one embodiment, the function prompt bar 751 further comprises a static differential display area among all the function icons, wherein the differential display area is sized to substantially cover one function icon. The processor 20 canceling the differentiated display of the first function icon and the differentiated display of the second function icon includes: and moving the first functional icon out of the differential display area, and moving the second functional icon into the differential display area. Likewise, the processor 20 canceling the differentiated display of the first function icon and the differentiated display of the third function icon includes: and moving the first functional icon out of the differential display area, and moving the third functional icon into the differential display area. For example, all the function icons move simultaneously in the direction opposite to the switching direction along with the switching of the functions, and accordingly, a previously hidden function icon is newly displayed in the icon bar, and a previously displayed function icon is correspondingly hidden. Taking fig. 7 as an example, a first switching instruction is received, which may activate the function B or may activate the function D, that is, the first switching instruction may correspond to a left switching function or a right switching function; assuming that function B is activated, all function icons move rightwards at the same time, the activated function is changed to B, the position of the original B icon is replaced by the A icon, the C icon moves to the position of the original D icon, and the D icon is hidden. Similarly, taking fig. 7 as an example, the received second switching instruction may activate function B or activate function D, that is, the second switching instruction may correspond to the left switching function or the right switching function; assuming function D is activated, all function icons move to the left at the same time, the activated function becomes D, and the three icons on the icon bar become CDE in turn. The function icon entering the differentiation display area is a function icon corresponding to a currently activated function, and the processor 20 performs differentiation display only on the function icon in the differentiation display area and displays a corresponding character identifier near the function icon.
In summary, in the function switching manner provided by the invention, the function prompt bar is in a bar shape, occupies a small display area, can be well adapted to the ultrasonic desktop computer and the portable computer, and can make a user clearly see the currently activated function and know the next switched function, thereby facilitating the user to switch the functions. And through the setting of button, the user can switch over the function through blind operation even, has improved the efficiency that the supersound was swept and has looked into.
In an optional embodiment, if a touch screen is correspondingly installed on the display, function switching may be performed in a manner shown in fig. 11, specifically, the method includes:
step 1', the processor 20 displays a function prompt bar on a display interface of the display; wherein, the function prompt bar simultaneously displays at least two function icons. Similarly, the function prompt bar may display only a part of the function icons at the same time, which is substantially the same as the above embodiment, in which the switching instruction is generated by the first button a and the second button b, and the switching instruction is generated by the touch screen in this embodiment, and other details are the same, so details are not described here. Of course, the function prompt bar may also display all the function icons, and the latter is taken as an example for explanation in this embodiment, and all the function icons are tiled in the function prompt bar. Each function icon corresponds to one function of the track ball or the touch pad respectively, and a first function icon corresponding to the currently activated function is displayed in a differentiated mode.
Step 2', when the processor 20 receives a selection instruction input by the user through the touch screen, that is, the user clicks the function icon corresponding to the function to be activated on the touch screen, the processor 20 closes the function corresponding to the first function icon and activates the function corresponding to the function icon selected by the selection instruction, cancels the differentiated display of the first function icon, and differentially displays the function icon selected by the selection instruction. The user can directly select the function icon to activate the required function, which is also very convenient.
