All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It is also to be understood that the terminology used in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
The embodiment of the invention provides a highlighting and highlighting method for an image selected area, which is mainly applicable to a display, such as a mini-led display, for example, in which brightness of each area block of a backlight partition can be independently adjusted.
As shown in fig. 1, the method for highlighting the selected region of the image includes the steps of: S10-S30.
S10, acquiring an image selected area of the mouse cursor in real time.
The PACS image is displayed on a mini-led display through a host computer such as a computer, at the moment, a doctor moves a mouse to search a desired part from the image, and an image selection area can be obtained through the position selected by the doctor through the mouse.
It should be noted that, the selection condition herein may be determined according to the actual situation, for example, when the time that the mouse cursor stays in a certain image area reaches a preset time, it represents that the image area is selected, and the size of the selected area in this selection manner may be preset, that is, how large an area around the mouse cursor is centered may be set as the size of the selected area. Also, for example, a selection condition of clicking a left button or a right button of the mouse, or the like, is selected by clicking, double clicking, or the like, and the size of the selected area in this selected manner may be set in advance, that is, how large an area around the center of the mouse cursor is may be set as the size of the selected area. For another example, the selection mode may directly use the frame selection range as the size of the selection area by dragging the frame selection range with the mouse as the selection condition.
S20, determining the backlight area of the display where the image is located according to the selected area of the image.
In one embodiment, the step S20 specifically includes the following steps: S201-S204.
S201, generating a binarized picture matched with the resolution of the display.
The generated binarized picture acts as a yes mapping, i.e. synchronizing the highlight area selected by the mouse cursor into the backlight partition of the display. The resulting binarized picture is matched to the resolution of the display, ensuring that for each possible point on the screen there is a corresponding point on the binarized picture. This ensures that the highlighting will be accurately overlaid to the corresponding position on the screen.
S202, marking an image selected area of a mouse cursor in the binarized picture.
Since the picture is binarized, meaning that each pixel is not black or white (or not 0 or 1), this approach greatly simplifies the processing logic. In this case, 0 represents a normal backlight area, and 1 represents a highlight area where an increase in brightness is required. And marking the pixel point of the image selected area of the mouse cursor as 1, namely marking the area marked as 1 in the picture as the image selected area.
S203, mapping the selected image area into an area block of the backlight partition.
Since the backlight module of the mini-LED liquid crystal panel can be logically divided into a plurality of small area blocks of backlight partitions, each area block is composed of a group of LED lamps, and the brightness can be controlled independently. The area that needs to be highlighted (delta) (the area where the pixel point marked 1 in the binarized graph is located) is mapped onto each area block of the backlight module.
S204, counting the number and the position sequence of the area blocks of the mapped backlight partition to obtain the backlight area of the display where the selected area of the image is located.
Each block of the area mapped to the need for highlighting will be counted and its sequence of positions in the backlight module recorded.
For steps S201-S204, the binary image is used as a map, and the processing speed of the binary image is very fast due to only two states, which allows the highlight area on the display to be dynamically adjusted in response to the movement of the mouse cursor. Meanwhile, the backlight area block needing to improve the brightness can be directly identified, and complex color information is not required to be processed, so that the processing difficulty is simplified. In addition, when the mouse moves, the binarized picture is updated according to the current position of the mouse, so that the highlight is synchronous with the cursor of the mouse and reflected on the display in real time, and the highlight area which can cope with real-time change is ensured.
S30, carrying out brightness enhancement treatment on the backlight area of the display where the image selected area is located, wherein the brightness of the image selected area after the brightness enhancement treatment is higher than that of the image unselected area.
In one embodiment, the step S30 specifically includes the following steps: S301-S302.
S301, setting a brightening factor.
The brightness enhancement factor refers to a numerical parameter used to adjust the brightness level, and may be a multiplier or an increment value.
S302, adjusting the area blocks of all the mapped backlight partitions according to the brightness enhancement factors so as to realize brightness enhancement processing on the backlight area of the display where the selected area of the image is located.
It should be noted that, the brightness enhancement factors that can be allocated to all the area blocks of all the backlight partitions according to the actual needs may be the same or different, for example, if the allocation is different, the brightness of a certain part of the area blocks is increased to a first brightness value, and the rest is increased to a second brightness value, where the brightness of the first brightness value and the second brightness value are different, which has the advantage that the brightness enhancement factors can be set according to the preference of the doctor, and further improves the use experience of the doctor.
The autonomous operation of moving the mouse by the doctor is used for determining the local brightening position, so that the doctor can flexibly select in the use process, and the condition for carefully analyzing the details of the PACS image is provided, thereby being beneficial to more accurately diagnosing the illness state of the patient and improving the diagnosis efficiency and accuracy of the doctor. In addition, the method is independent of the image signal input by the user, namely, is not influenced by the type of the image input signal, and does not influence the quality of the image.
In an embodiment, step S10 further includes the steps of: S5-S6.
S5, judging whether to enter a highlighting mode.
If yes, go to step S10, if no, go to step S6.
And S6, if not, displaying the image according to the preset normal brightness.
For steps S5-S6, the design herein achieves mode selectivity, and the doctor can choose whether to enter the highlighting mode according to his own needs, so that the use is more humanized.
The embodiment of the application also provides an image selection area highlighting and highlighting device, which is used for executing the steps in any embodiment of the image selection area highlighting and highlighting method.
