The processor 150 can execute the recording in storage. The program codes, software modules, instructions, etc. in the device 140 are used to implement the method for adjusting the display effect according to the embodiment of the present invention.

FIG. 2 is a flowchart of a method for adjusting a display effect according to an embodiment of the present invention. Referring to FIG. 2 , the method of this embodiment is applicable to the display system 10 in the above-mentioned embodiment. The following describes how to control the display effect of the first display screen 110 according to the user's line of sight in this embodiment in combination with various elements in the display system 10 . detailed steps.

In step S201 , the processor 150 detects the gaze position of the user on the first display screen 110 through the gaze sensing device 130 . In detail, the processor 150 can obtain the sight line information through the sight line sensing device 130, and the above sight line information can include sight line direction, eye position information, face orientation, pupil position, etc., and the above sight line information determines the user's first A gaze position on the display screen 110 is displayed. The gaze position may include a screen coordinate position on the first display screen 110 or a partial display area on the first display screen 110 .

In step S202 , the processor 150 acquires the indicated position of the input device 120 on the first display screen 110 . The input device 120 can indicate a pointing position on the first display screen 110 in response to the user's operation. The above-mentioned indicated position may include a touch position or a mouse/cursor position, and so on. For example, the user can indicate the mouse position on the first display screen 110 by controlling the mouse. Alternatively, the user may indicate one or more touch positions on the first display screen 110 through a stylus.

In step S203, the processor 150 configures at least one attention area on the first display screen 110 according to the gaze position and the indicated position. Here, the display area of the first display screen 110 may include at least one area of interest and a non-concerned area that does not overlap with the area of interest. Specifically, when the user manipulates the display system 10 , in addition to the gaze position determined according to the gaze information, the processor 150 can also refer to the mouse position or the touch position to identify at least one area of interest of the user on the first display screen 110 . The area of interest is a partial area of the display area of the first display screen 110 . The present invention does not limit the shape of the region of interest, which can be a rectangle or an ellipse or the like. The non-attention area and the attention area do not overlap with each other, and the non-attention area surrounds the attention area. In other words, the non-focus area may be other partial areas other than the focus area in the display area of the first display screen 110 .

In step S204 , the processor 150 performs blurring processing on the non-focus area on the first display screen 110 . In some embodiments, the processor 150 may configure the image resolution of the display image in the area of interest to be higher than the image resolution of the display image in the non-focus area area. In some embodiments, the processor 150 may reduce the definition of the non-interest area by using the image processing function of the GPU, so as to perform blurring processing on the non-interest area on the first display screen 110 . The aforementioned sharpness may include sharpness, contrast, resolution, or a combination thereof. In other words, the displayed content in the area of interest that the user pays attention to is clear, but the displayed content in the non-attention area is blurred. Based on this, since the intentional voyeur cannot know the actual attention area of the user in real time and accurately, they cannot clearly view the screen content displayed on the first display screen 110 . In this way, the effect of protecting the privacy of use can be achieved without disturbing the user.

In some embodiments, the processor 150 may further configure the ambiguity of different regions in the non-interest region to increase in stages with the region of interest as the center. Specifically, the non-interest area may include a first sub area and a second sub area, and the first sub area surrounds the attention area and the second sub area surrounds the first sub area. The processor 150 can control the first sub-area on the first display screen 110 to display with the first blur degree, and control the second sub-area on the first display screen 110 to display with the second blur degree. Here, the first blurriness is different from the second blurriness. In other words, the processor 150 may configure different display parameters for the first sub-area and the second sub-area, so as to control the first sub-area and the second sub-area to be displayed with different blurring degrees respectively.

For example, FIG. 3 is a schematic diagram of adjusting the display effect according to an embodiment of the present invention. Referring to FIG. 3 , the first display screen 110 displays images in the display area R1 . After the processor 150 determines a certain region of interest F1 in the display region R1 according to the gaze position or/and the indicated position of the input device 120, the processor 150 may further divide the non-interested region NF into the first sub-region NF1 and the second sub-region NF1 Area NF2. The first sub-region NF1 surrounds the region of interest F1 and the second sub-region NF2 surrounds the first sub-region NF1. Therefore, the processor 150 can control the first sub-area NF1 to display with the first blur degree, and control the second sub-area NF2 to display with the second blur degree. Here, the first blurriness is different from the second blurriness. In other words, in some embodiments, the processor 150 may configure the image resolution of the display images in the first sub-area NF1 to be higher than the image resolution of the display images in the second sub-area NF2. From another point of view, the area of interest F1 is displayed at the first image resolution; the first sub-area NF1 is displayed at the second image resolution; and the second sub-area NF2 is displayed at the third image resolution . Here, the first image resolution is higher than the second image resolution, and the second image resolution is higher than the third image resolution. However, FIG. 3 is only an example, and the size and shape of the region of interest F1, the first sub-region NF1 and the second sub-region NF2 are only examples, and are not intended to limit the present invention.

In some embodiments, the processor 150 can determine the distance between the gaze position and the pointing position. Then, the processor 150 may determine the number and area of the attention area according to the distance. In other words, the number and area of the attention area can be determined according to the distance between the gaze position and the pointing position. In this way, even if the pointing position of the mouse is not close enough to the gaze position, it is convenient for the user to find the mouse or cursor on the first display screen 110 . Alternatively, when the gaze position is quite close to the indicated position, it means that the user is concentrating on a specific display area, and thus the range of the attention area can be expanded.

In some embodiments, according to the distance between the gaze position and the pointing position, the processor 150 may decide to configure two smaller ROIs or configure one larger ROI. In detail, if the distance between the gaze position and the pointing position is smaller than the threshold value, the number of attention areas is one and the area of the attention areas is the first area. The above threshold value can be set according to actual requirements, which is not limited in the present invention. On the other hand, if the distance between the gaze position and the pointing position is not less than the critical value, the number of attention areas is two and the area areas of the attention areas are the second area and the third area, respectively. The first area is larger than the second area and the third area. The second area of the area of interest associated with the gaze location may be larger than the third area of the area of interest associated with the indicated location.

For example, FIG. 4A and FIG. 4B are schematic diagrams of adjusting the display effect according to an embodiment of the present invention. Referring to FIG. 4A , the processor 150 can obtain the gaze position P1 through the line of sight detection device 130 and obtain the indicated position P2 of the input device 120 (a mouse is used here as an example). If the distance between the gaze position P1 and the pointing position P2 is not less than the threshold value, the processor 150 can configure the attention area F2_1 according to the gaze position P1 and configure the attention area F2_2 according to the pointing position P2. The gaze position P1 and the pointing position P2 may be, for example, the center points of the attention area F2_1 and the attention area F2_2, respectively. In addition, the processor 150 may configure the area of the area of interest F2_1 to be A pixels, and configure the area of the area of interest F2_2 to be B pixels, where the integer A is greater than the integer B.

On the other hand, referring to FIG. 4B , similarly, the processor 150 can acquire the gaze position P3 through the sight line detection device 130 and acquire the indicated position P4 of the input device 120 . If the distance between the gaze position P3 and the pointing position P4 is smaller than the threshold value, the processor 150 may configure the attention area F2_3 according to the gaze position P1 and the pointing position P4. For example, the center point of the line connecting the gaze position P1 and the pointing position P2 may be the center point of the attention area F2_3. In addition, the processor 150 may configure the area of the region of interest F2_3 to be C pixels. Here, the integer C is greater than the integer A and the integer B.

However, the implementation of the present invention is not limited to the above description, and the contents of the above-mentioned embodiments may be appropriately changed according to actual needs. For example, in another embodiment of the present invention, the electronic device can also adjust the display effect of another display screen according to the sight lines of multiple users. Hereinafter, another embodiment will be described in detail.

The difference is that the display system 50 of this embodiment further includes a second display screen 160 .

The second display screen 160 is a display device that can provide a display function, such as a liquid crystal display, a light emitting diode display, a field emission display, an organic light emitting diode display or other types of displays, and the present invention is not limited thereto. The second display screen 160 is, for example, a desktop monitor externally connected to a notebook computer, a tablet computer, a mobile phone, or the like. Alternatively, the first display screen 110 and the second display screen 160 may be respectively implemented as display devices of two notebook computers. Alternatively, the display system 50 including the first display screen 110 and the second display screen 160 may be implemented as a notebook computer with dual screens.

FIG. 6 is a flowchart of a method for adjusting a display effect according to an embodiment of the present invention. Referring to FIG. 6 , the method of this embodiment is applicable to the display system 50 in the above-mentioned embodiment. The following describes the detailed steps of adjusting the display effect in this embodiment in combination with various elements of the display system 50 .

In step S601 , the processor 150 detects the gaze position of the user on the first display screen 110 through the gaze sensing device 130 . In step S602 , the processor 150 obtains the indicated position of the input device 120 on the first display screen 110 . In step S603, the processor 150 configures at least one attention area on the first display screen 110 according to the gaze position and the indicated position. In step S604 , the processor 150 performs blurring processing on the non-focus area on the first display screen 110 . The operations of steps S601 to S604 are similar to those of steps S201 to S204 in FIG. 2 , and are not repeated here.

It should be noted that, in step S605 , in response to the user watching the second display screen 160 , the processor 150 detects another gaze position of the user on the second display screen 160 through the line-of-sight sensing device 130 . Next, in step S606 , the processor 150 configures another attention area on the second display screen 160 according to another gaze position on the second display screen 160 . The display area of the second display screen 160 includes another area of interest and another area of non-interest that does not overlap with the other area of interest. Specifically, in some embodiments, the processor 150 may determine that the user is viewing the first display screen 110 or the second display screen 160 according to the sensing data of the sight line detection device 130 , so as to determine the user viewing the first display screen 110 or the second display screen 160 according to the sensing data of the sight line detection device 130 The measurement data is used to obtain the gaze position on the first display screen 110 or another gaze position on the second display screen 160 .

In some embodiments, the line-of-sight sensing device 130 may include a first line-of-sight sensor disposed on a screen edge of the first display screen 110 and a second line-of-sight sensor disposed on a screen edge of the second display screen 160 . The first line-of-sight sensor and the second line-of-sight sensor may be a sensing device such as an RGB camera, an infrared camera, or an eye tracker, which can track a user's line of sight. The processor 150 can determine that the user is viewing one of the first display screen 110 and the second display screen 160 according to the sensing data of the first line of sight sensor and the sensing data of the second line of sight sensor.

In one embodiment, when both the first line of sight sensor and the second line of sight sensor are eye trackers, the processor 150 can determine whether the user is watching the first display screen 110 according to the line of sight vectors output by the two eye trackers or the second display screen 160. Alternatively, in an embodiment, when both the first line-of-sight sensor and the second line-of-sight sensor are RGB cameras, the processor 150 can calculate the depth information of the user according to the facial images provided by the two RGB cameras, and According to the depth information and the face orientation and pupil position in the face image, it is determined that the user is viewing the first display screen 110 or the second display screen 160 .

In step S607 , the processor 150 performs blurring processing on another area of interest on the second display screen 160 and configures another area of interest on the second display screen 160 to provide an enlarged display effect. Based on the flow of FIG. 6 , in one embodiment, in response to the user viewing the first display screen 110 , the processor 150 may determine the area of interest on the first display screen 110 and determine the area of interest on the second display screen 160 for the entire display area of the second display screen 160 The blurring process is performed with the non-interested area on the first display screen 110 . In one embodiment, in response to the user viewing the second display screen 160, the processor 150 may determine another area of interest on the second display screen 160, and determine the entire display area of the first display screen 110 and the second display screen Another area of non-interest on 160 is blurred.

It is worth mentioning that, in this embodiment, the processor 150 may further configure another area of interest on the second display screen 160 to provide an enlarged display effect. In other words, as the user's line of sight pans on the second display screen 160, another area of interest will move with the line of sight and display the content of the screen in an enlarged manner. In some embodiments, the processor 150 may acquire the depth information of the user relative to the second display screen 160 and determine the magnification ratio of the enlarged display effect according to the depth information of the user relative to the second display screen 160 . The magnification will increase with the depth information. For example, when both the first line-of-sight sensor and the second line-of-sight sensor are RGB cameras, the processor 150 can calculate the depth information of the user according to the facial images provided by the two RGB cameras. The processor 150 can determine the magnification by looking up the table according to the depth information. In this way, if the screen size of the second display screen 160 is small or far away from the user, the user can clearly see the displayed content while protecting privacy.

For example, FIG. 7 is a schematic diagram of a method for adjusting a display effect according to an embodiment of the present invention. Referring to FIG. 7 , in this embodiment, it is assumed that the line-of-sight sensing device 130 includes an RGB camera 111 disposed on the first display screen 110 and an RGB camera 161 disposed on the second display screen 160 . The processor 150 can determine that the user is viewing the second display screen 160 according to at least two facial images captured by the RGB camera 111 and the RGB camera 161 respectively, and estimate the depth information of the user accordingly. Then, the processor 150 can estimate the gaze position on the second display screen 160 according to the facial images, and determine the attention area F7 on the second display screen 160 accordingly. Afterwards, the processor 150 may enlarge and display the display content in the area of interest F7, and perform blurring processing on the display content of the non-interest area NF7. At the same time, the processor 150 may perform blurring processing on the display content of the display area R7 in the first display screen 110 .

To sum up, in the embodiment of the present invention, the area size, position and number of the area of interest can be dynamically determined according to the user's line of sight and the indicated position of the input device. By clearly displaying the content in the area of interest and blurring the content in the non-concerned area, it can prevent others from peeping at the private information displayed on the display screen without affecting the user's operating experience and display brightness and color. In addition, in the application scenario of multiple display screens, the area of interest can be configured to provide an enlarged display effect, and the magnification ratio of the enlarged display effect can be determined according to the user's depth information, so that the user can more clearly see the small size of the screen or the distance The display content of the display screen is farther away, and at the same time, the display content that the user does not pay attention to is prevented from being peeped by others.
