Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.
"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled.
The applicant has found that when an image formed by a medical device is observed by a medical device display device, a high-brightness display device is required for a medical worker to see more image details, which is important for auxiliary diagnosis (such as breast examination) by a medical device such as an X-ray machine. However, if the medical staff works in front of the high-brightness display device for a long time, the eye fatigue of the medical staff is accelerated, and the attention of the medical staff is not focused, so that the efficiency and even the accuracy of the diagnosis work are affected.
The applicant has also found that it is generally necessary to use an additional sensing element in the prior art, and to decide whether to trigger the backlight adjustment (brightness adjustment) of the display device of the medical apparatus according to the sensing signal of the sensing element. However, not only does this require additional provision of the sensing element, but it is also likely to cause an error due to misjudgment of the sensing element. For example, the sensing element senses that there is a user nearby, but the user does not necessarily intend to observe the display content of the display device, so that the accuracy of backlight adjustment of the display device is not high.
Therefore, how to use the backlight more economically and efficiently while maintaining a high brightness display will be a new requirement for medical-grade display devices following the DICOM standard.
The contents of the various exemplary embodiments of the present invention are described below with reference to the accompanying drawings.
Referring first to fig. 1, fig. 1 is a schematic flow chart of a brightness adjustment method for a display device of a medical apparatus according to an embodiment of the invention. In the embodiment shown in fig. 1, the brightness adjustment method 100 for the display device of the medical apparatus includes:
step S110: identifying content to be displayed and determining a display category; and
step S120: and sending the brightness control signal to the display device.
In step S110, a content to be displayed is identified and a display category to which the content to be displayed belongs is determined. Generally, different contents may be displayed using the medical device display apparatus according to application scenarios. The application scenarios described above can be, for example, an operating room, a radiograph reading room, etc., and the present invention is not limited thereto. Meanwhile, the operation mode of the medical equipment display device is different, and the display content is also different. For example, the present invention is not limited to the pre-configuration mode, the exposure mode, the viewing mode, and the maintenance mode. The invention aims to automatically identify different display contents, such as image contents such as 'display image window', video contents such as 'display video window', and character contents such as 'display patient registration information window', by using an image system of medical equipment. In other words, in the illustrative embodiment, the display content may include, but is not limited to, image content, video content, textual content, and the like. In an embodiment, for example, the display device may be set to display with the highest brightness in a ZOOM-out (ZOOM) mode, which is not limited by the invention.
According to the requirement of practical application, the display category corresponding to the content to be displayed can be preset. In an embodiment, a set of display luminances may be preset, wherein each display luminance corresponds to one or more display categories. For example, a set of display brightness may be preset corresponding to the above-exemplified contents of images, videos, texts, etc., and the set of display brightness may include image display brightness, video display brightness, text display brightness, etc. Alternatively, the set of display luminances may also include a high display luminance, a low display luminance, and the like luminance division. The high display brightness is brightness meeting the brightness requirement of medical staff for reading images or videos and other imaging data, and the low display brightness is brightness meeting the requirement of the medical staff for browsing characters and other information with low brightness requirements or low brightness of the power-saving mode when effective contents are not displayed. Those skilled in the art can select and set different display brightness according to the actual application requirements, for example, three levels of brightness, i.e., high, medium, and low, can be set to respectively correspond to the power saving mode when the medical care personnel reads the image information and the text information and does not display the effective content, and the invention is not limited thereto.
In step S120, a brightness control signal is sent to the display device according to a preset display brightness corresponding to the display category. Thereby, the backlight of the display device is selected and set correspondingly by judging the display content.
The invention uses the automatic image recognition technology, controls the display device to adjust the brightness according to different requirements of different application scenes and different display contents on the brightness, can reduce the energy consumption of the display device and improve the operation efficiency, and obviously prolongs the service life of the display device while ensuring the stable image quality. In addition, a user can preset different application scenes according to the requirement on the brightness, the control device of the medical equipment can automatically identify the current application scene, and the display device is controlled to output the preset backlight brightness.
The invention can adjust the backlight brightness of the display device by automatically identifying the display content without changing the main hardware structure (such as power supply control, liquid crystal panel and backlight structure) of the current medical equipment or display device. In practice, the skilled person can adapt the backlight control unit and the related firmware of the display device according to the actual application needs. Specifically, when the display device receives various brightness control signals sent by an image system of the medical equipment, the backlight control unit of the display device reads the input signals and outputs the control signals according to the set logic, and the control signals are sent to the backlight working circuit of the display device, so that the brightness of the display device is adjusted to the required backlight level.
The technical solution provided by the present invention can be flexibly applied by those skilled in the art according to the needs, for example, the backlight change switching can be set to occur simultaneously with the application scene switching, and can be further set to keep the brightness unchanged in the same application scene, so that the brightness switching hardly has obvious influence on the user (such as medical staff). For example, the image content may be kept displayed with high brightness at all times while the doctor reads the film.
The present invention further provides a medical device, and in an embodiment, the medical device may be various X-ray machine devices or CT devices, which is not limited thereto.
