Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of an ambulatory medical terminal provided in an embodiment of the present application. Referring to fig. 1, the mobile medical terminal may include a housing 01, a lens module 02, and a light emitting assembly 03.
Wherein, the housing 01 of the mobile medical terminal may be provided with a first through hole (not shown in fig. 1) and a second through hole (not shown in fig. 1). The second via may be disposed proximate to the first via. The lens module 02 may be disposed in the first through hole, and the light emitting element 03 may be disposed in the second through hole. Correspondingly, the light emitting element 03 can be disposed next to the lens module 02.
Optionally, the lens module 01 may be an optical zoom lens module.
Further, as shown in fig. 1, the mobile medical terminal may further include: a volume adjusting key 04, a power supply key 05, a data line interface 06 and a loudspeaker 07 which are arranged on the shell 01.
The embodiment of the application provides a brightness adjusting method of a mobile medical terminal, which can be applied to the mobile medical terminal, such as the mobile medical terminal shown in fig. 1. As shown in fig. 1, the mobile medical terminal may include: the light emitting assembly 02 and the lens module 03, referring to fig. 1, the method may include:
In the embodiment of the application, after the mobile medical terminal receives the lens module starting instruction aiming at the mobile medical terminal to start the lens module, the current lens magnification of the lens module can be determined.
And 102, determining the target brightness of the light-emitting component based on the lens magnification.
After the lens magnification of the lens module is determined, the mobile medical terminal can determine the target brightness of the light emitting component of the mobile medical terminal based on the lens magnification. Wherein the target brightness is positively correlated with the lens magnification.
That is, the larger the current lens magnification of the mobile medical terminal is, the stronger the target light-emitting brightness of the light-emitting component is. The smaller the magnification of the lens is, the weaker the target light-emitting brightness of the light-emitting component is. Therefore, on the premise of ensuring the endurance time of the mobile medical terminal, the lens module can be ensured to acquire more image details.
And 103, adjusting the light-emitting brightness of the light-emitting component to the target light-emitting brightness.
After the mobile medical terminal determines the target brightness of the light-emitting component, the brightness of the light-emitting component can be automatically adjusted to the target brightness.
In summary, the embodiment of the present application provides a brightness adjustment method for a mobile medical terminal, where the mobile medical terminal may determine a target brightness based on a lens magnification of a lens module of the mobile medical terminal, and may automatically adjust the brightness of a light-emitting component to the target brightness. Because the brightness of the mobile medical terminal is not required to be manually adjusted by medical staff, the brightness adjusting efficiency of the mobile medical terminal is effectively improved. Moreover, the operation of medical staff can be reduced, so that the user experience of the medical staff when using the mobile medical terminal is improved.
Fig. 2 is a flowchart of another brightness adjustment method for an ambulatory medical terminal according to an embodiment of the present disclosure, where the method may be applied to an ambulatory medical terminal, such as the ambulatory medical terminal shown in fig. 1, and the ambulatory medical terminal may include a lens module 02 and a light-emitting assembly 03. Referring to fig. 2, the method may include:
After receiving a starting instruction for a lens module of the mobile medical terminal, the mobile medical terminal can detect whether the magnification of the lens module changes. If the mobile medical terminal determines that the lens magnification of the lens module is changed, step 202 may be executed. If the mobile medical terminal determines that the lens magnification of the lens module is not changed, step 203 may be executed, that is, the mobile medical terminal may determine the target brightness of the light emitting element directly based on the lens magnification.
In the embodiment of the application, a camera application may be installed in the mobile medical terminal, and the camera application may be a system application or a third party application. If the medical staff needs to use the mobile medical terminal to view the observation object, the medical staff can touch the icon of the camera application on the mobile medical terminal. At this time, the mobile medical terminal can receive a starting instruction for the lens module and can respond to the starting instruction to start the lens module.
Optionally, the mobile medical terminal may display a brightness automatic adjustment switch control. If the medical staff needs to move the medical terminal to automatically adjust the brightness of the light-emitting component after the magnification of the lens module is changed, the medical staff can touch the brightness automatic adjustment switch control. Correspondingly, the mobile medical terminal can respond to the touch operation of the medical staff for the brightness automatic adjustment switch control, and the brightness automatic adjustment function of the mobile medical terminal is started. After the brightness automatic adjustment function is started, the mobile medical terminal can detect whether the lens magnification of the lens module changes or not after receiving a starting instruction for the lens module.
If the medical staff does not need to move the medical terminal to adjust the brightness of the light-emitting component after the magnification of the lens module is changed, the medical staff can touch the brightness automatic adjustment switch control again. Correspondingly, the mobile medical terminal can respond to the touch operation of the medical staff for the brightness automatic adjustment switch control again, and the brightness automatic adjustment function of the mobile medical terminal is forbidden.
For example, referring to fig. 4, the mobile medical terminal may display an automatic brightness adjustment control 01 and a function description 02 of the automatic brightness adjustment control 01, where the function description may be a text "turn on an automatic brightness adjustment switch, and the mobile medical terminal may automatically adjust the brightness of the light emitting component after the magnification of the lens module changes". As shown in fig. 4, the medical staff may touch the brightness automatic adjustment control 01, and the mobile medical terminal may respond to the touch operation to start the brightness automatic adjustment function.
In an optional implementation manner, after the lens module of the mobile medical terminal is started, if the lens module acquires an image of the observation object, the medical staff can touch the zoom key of the mobile medical terminal to adjust the focal length of the lens module. At this time, the mobile medical terminal can receive the zoom instruction for the lens module, and can adjust the lens magnification of the lens module to the lens magnification indicated by the zoom instruction. The mobile medical terminal may then compare the adjusted lens magnification to the lens magnification before adjustment. If the mobile medical terminal determines that the adjusted lens magnification is different from the lens magnification before adjustment, it may be determined that the lens magnification of the lens module is changed, and then step 202 may be performed. If the mobile medical terminal determines that the adjusted lens magnification is the same as the lens magnification before adjustment, it may be determined that the lens magnification of the lens module is not changed, and then step 203 may be performed. The zoom key may be a physical key, or the zoom key may also be a virtual key.
It should be noted that, if the medical staff continuously touches the zoom button for multiple times, correspondingly, the mobile medical terminal may receive multiple zoom instructions, and a time interval between any two adjacent zoom instructions in the multiple zoom instructions is less than the duration threshold. In this case, the mobile medical terminal may adjust the lens magnification of the lens module to the lens magnification indicated by the zoom instruction received the last time. Wherein, the time length threshold value can be pre-stored in the mobile medical terminal.
In another alternative implementation manner, after the lens module of the mobile medical terminal is started, the medical staff may aim the lens module at the observation object. At the moment, the mobile medical terminal can automatically adjust the lens magnification of the lens module. Then, the mobile medical terminal can compare the adjusted lens magnification with the lens magnification before adjustment. If the mobile medical terminal determines that the adjusted lens magnification is different from the lens magnification before adjustment, it may be determined that the lens magnification of the lens module is changed, and then step 202 may be performed. If the mobile medical terminal determines that the adjusted lens magnification is the same as the lens magnification before adjustment, it may be determined that the lens magnification of the lens module is not changed, and then step 203 may be performed.
If the mobile medical terminal determines that the lens magnification of the lens module is changed, the changed lens magnification of the lens module can be determined.
After the lens magnification of the lens module is determined, the mobile medical terminal can determine the target brightness of the light emitting component of the mobile medical terminal based on the lens magnification and the corresponding relation between the prestored brightness and the lens magnification. Wherein, the target brightness of the light-emitting component is positively correlated with the magnification of the lens. That is, the larger the lens magnification is, the stronger the target luminance of the light emitting component is; the smaller the lens magnification, the weaker the target light emission luminance of the light emitting element.
The larger the lens magnification of the lens module is, the stronger the target brightness of the light-emitting component is, so that the light-emitting component can provide stronger light when the lens module collects more detailed images. The light-emitting component can provide a brighter image acquisition environment for the lens module, so that more image details can be acquired by the lens module. Because when the lens magnification of the lens module is small, namely the lens module does not need to collect more image details, the target luminous intensity of the luminous assembly can be weaker, the energy consumption of the mobile medical terminal can be reduced on the premise that the lens module can clearly collect images, and the endurance time of the mobile medical terminal is effectively prolonged.
Optionally, the mobile medical terminal may record the correspondence between the brightness and the lens magnification in a table form. For example, referring to table 1, table 1 shows a correspondence of light emission luminance to lens magnification. As can be seen from table 1, if the lens magnification of the lens module determined by the mobile medical terminal is 0%, that is, the focal length of the lens module is not changed, it can be determined that the target luminance of the light emitting component is 1-level luminance. If the mobile medical terminal determines that the lens magnification of the lens module is 300%, the target brightness of the light-emitting component can be determined to be 5-level brightness. Wherein, the higher the level of the luminous brightness of the luminous component is, the stronger the illumination intensity of the luminous component is.
TABLE 1
Optionally, in this embodiment of the application, after determining the lens magnification of the lens module, the mobile medical terminal may further detect whether the lens magnification is greater than a lens magnification threshold. If the mobile medical terminal determines that the lens magnification is smaller than or equal to the lens magnification threshold, the target light-emitting brightness of the light-emitting component can be determined based on the lens magnification. If the mobile medical terminal determines that the lens module is larger than the lens magnification threshold, the target luminous brightness of the luminous module can be directly determined to be the maximum luminous brightness of the luminous component. The lens magnification threshold may be a maximum lens magnification of the lens module.
For example, assuming that the lens magnification of the lens module determined by the mobile medical terminal is 200%, and the correspondence between the target light-emitting brightness and the lens magnification is shown in table 1, the mobile medical terminal may determine that the target light-emitting brightness of the light-emitting component is 4-level light-emitting brightness.
And step 204, adjusting the light-emitting brightness of the light-emitting component to the target light-emitting brightness.
After the mobile medical terminal determines the light-emitting brightness of the light-emitting component, the light-emitting brightness of the light-emitting component can be adjusted to the target light-emitting brightness.
In the embodiment of the present application, the light emitting assembly may include one light emitting unit. Alternatively, the light emitting assembly may include a plurality of light emitting units, and the plurality of light emitting units may be uniformly arranged in a ring shape.
For a scene that the light-emitting assembly comprises a light-emitting unit, the mobile medical terminal can directly adjust the light-emitting brightness of the light-emitting unit to the target light-emitting brightness. Optionally, the mobile medical terminal may adjust the brightness of the light emitting unit by adjusting the magnitude of the driving current of the light emitting unit.
For a scene in which the light-emitting assembly comprises a plurality of light-emitting units, the mobile medical terminal can adjust the light-emitting brightness of the light-emitting assembly to the target light-emitting brightness through at least one of the following optional implementation manners.
In an optional implementation manner, the mobile medical terminal may adjust the number of the light-emitting units in the light-emitting state in the plurality of light-emitting units, so that the light-emitting brightness of the light-emitting assembly is the target light-emitting brightness. Wherein, the light-emitting brightness of the light-emitting component can be positively correlated with the number of the light-emitting units in the light-emitting state. That is, the greater the number of light-emitting units in a light-emitting state, the stronger the light-emitting luminance of the light-emitting element.
For example, if the light-emitting brightness of any light-emitting unit included in the light-emitting assembly is a fixed value when the light-emitting assembly is in the light-emitting state, after the mobile medical terminal determines the target light-emitting brightness of the light-emitting assembly, the mobile medical terminal may determine the target number of light-emitting units that need to be in the light-emitting state based on the target light-emitting brightness and the light-emitting brightness of the light-emitting units. Then, the mobile medical terminal can light the light-emitting units with the target number, so that the light-emitting brightness of the light-emitting component is the target light-emitting brightness.
In another optional implementation manner, the mobile medical terminal may adjust the light-emitting brightness of at least one of the plurality of light-emitting units in a light-emitting state, so that the light-emitting brightness of the light-emitting assembly is the target light-emitting brightness.
For example, if any light-emitting unit included in the light-emitting device is in a light-emitting state, the light-emitting brightness of the light-emitting unit may vary, that is, the light-emitting brightness of the light-emitting unit is not a fixed value. The mobile medical terminal, after determining the target light-emission luminance of the light-emitting assembly, may determine the specified light-emission luminance of each light-emitting unit based on the target light-emission luminance and the luminance variation range of the light-emitting unit. Then, the mobile medical terminal can adjust the brightness of the light-emitting unit to the specified brightness, so that the brightness of the light-emitting component is the target brightness.
Fig. 5 is a schematic diagram of an observation object displayed by the mobile medical terminal under a first lens magnification provided in an embodiment of the present application, and fig. 6 is a schematic diagram of an observation object displayed by the mobile medical terminal under a second lens magnification provided in an embodiment of the present application. And the first lens magnification is larger than the second lens magnification. As can be seen from comparison between fig. 5 and fig. 6, for the same observation object a, under the first lens magnification, the observation object includes a target observation object a1 on the display screen of the ambulatory medical terminal, and the occupied area of the display area is larger. Under the second lens magnification, the target observed object a1 occupies a smaller area of the display area on the display screen of the ambulatory medical terminal.
Correspondingly, under the magnification of the first lens, the brightness of the light-emitting component of the mobile medical terminal can be stronger than that of the light-emitting component under the magnification of the second lens.
It should be noted that, after the mobile medical terminal adjusts the light-emitting brightness of the light-emitting component based on the lens magnification of the current lens module, if the lens magnification is not changed, the mobile medical terminal may keep the light-emitting brightness of the light-emitting component unchanged.
In the embodiment of the application, after determining the changed lens magnification of the lens module, the mobile medical terminal may further determine the target contrast ratio based on the lens magnification and the corresponding relationship between the contrast ratio and the lens magnification.
Wherein the contrast coefficient is inversely related to the lens magnification. That is, the larger the lens magnification, the smaller the contrast ratio, and the smaller the lens magnification, the larger the contrast ratio.
And step 206, adjusting the contrast of the image acquired by the lens module based on the target contrast coefficient.
After the mobile medical terminal determines the target contrast coefficient, the contrast of the image acquired by the lens module can be adjusted by adopting a contrast enhancement algorithm based on the target contrast coefficient so as to ensure the display effect of the image acquired by the lens module subsequently.
Optionally, the contrast enhancement algorithm may be a neighborhood statistics algorithm, and correspondingly, the target contrast coefficient may be the number of pixels included in the field of each pixel in the image collected by the lens module.
And step 207, displaying the image acquired by the lens module.
In the embodiment of the application, after the lens module collects the image, the mobile medical terminal can display the image collected by the lens module on a display screen of the mobile medical terminal so that medical staff can check the image.
Optionally, the mobile medical terminal can also respond to touch operation of the medical personnel for the photographing key, and store images acquired by the lens module.
Optionally, before displaying the image collected by the lens module, the mobile medical terminal may further perform image sharpening on the image collected by the lens module, so that the image collected by the lens module displayed by the display screen is clearer.
In this embodiment of the application, the process of the mobile medical terminal performing image sharpening on the image collected by the lens module may include: and determining a target sharpening coefficient based on the lens magnification of the lens module, and then carrying out image sharpening on the image acquired by the lens module by adopting an image sharpening algorithm based on the target sharpening coefficient so as to enhance the edge and the outline of the image. Wherein the target sharpening factor may be positively correlated with the lens magnification.
Optionally, the image sharpening algorithm may be a gaussian low-pass filtering algorithm, and accordingly, the target sharpening coefficient is a standard deviation of a gaussian distribution.
It should be noted that, the order of the steps of the brightness adjustment method for the mobile medical terminal provided in the embodiment of the present application may be appropriately adjusted, and the steps may also be increased or decreased according to the situation. For example, step 205 and step 206 may be deleted, that is, after the mobile medical terminal adjusts the light-emitting brightness of the light-emitting component to the target light-emitting brightness, the image collected by the lens module may be displayed. Any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application is covered by the protection scope of the present application, and thus the detailed description thereof is omitted.
In summary, the embodiment of the present application provides a brightness adjustment method for a mobile medical terminal, where the mobile medical terminal may determine a target brightness based on a lens magnification of a lens module of the mobile medical terminal, and may automatically adjust the brightness of a light-emitting component to the target brightness. Because the brightness of the mobile medical terminal is not required to be manually adjusted by medical staff, the brightness adjusting efficiency of the mobile medical terminal is effectively improved. Moreover, the operation of medical staff can be reduced, so that the user experience of the medical staff when using the mobile medical terminal is improved.
