[0019] The specific embodiments of this invention will be described in more detail below with reference to the schematic diagrams. The advantages and features of this invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this invention.
[0020] Figure 1 This is a block diagram of a screen display control device 100 provided according to an embodiment of this case.
[0021] This invention provides a screen control device 100, applicable to an electronic device 10, the electronic device 10 having a touch screen 12, the touch screen 12 being adapted to display a screen 200. In one embodiment, the electronic device 10 may be a portable electronic device, such as a smartphone, tablet computer, laptop computer, etc.
[0022] The screen display control device 100 includes an interface layer setting unit 120, a display area setting unit 140, and an interface layer status control unit 160.
[0023] The interface layer setting unit 120 is adapted to set an interface layer 210 on the top layer of the screen 200 in response to a start command EN. In one embodiment, the interface layer setting unit 120 may remove the interface layer 210 in response to an end command DIS.
[0024] The display area setting unit 140 is adapted to obtain a first touch trajectory TT1 through the interface layer 210, the first touch trajectory TT1 corresponding to a first area A1 of the screen.
[0025] The interface layer state control unit 160 is adapted to identify a shielding region AS based on the first region A1 and change the opacity of the interface layer 210 corresponding to the shielding region AS.
[0026] In one embodiment, the shielded area AS is the portion of the image 200 other than the first area A1. However, this embodiment is not limited to this.
[0027] In one embodiment, the interface layer state control unit 160 can reduce the transparency of the portion of the interface layer 210 corresponding to the shielded area AS, adjusting it from an opaque state with a transparency of 1 to a completely transparent state with a transparency of 0. In the opaque state, the image content of the shielded area AS will be completely shielded by the interface layer 210.
[0028] Please refer to the above as well. Figure 2 , Figure 2 This is a flowchart of a screen display control method provided according to an embodiment of this case. This screen display control method is applicable to an electronic device 10, which has a touch screen 12 adapted to display a screen 200. This screen control method can be used for... Figure 1 The screen display control device 100 shown includes the following steps.
[0029] First, as described in step S220, in response to a startup command EN, the screen control mode is entered, and an interface layer 210 is set at the top of the screen 200. This step can be performed by the interface layer setting unit 120.
[0030] Please refer to the above as well. Figure 3 , Figure 3It is a display Figure 2 An embodiment of step S220 in the process.
[0031] As shown in the left half of the figure, a sensor (not shown) can be installed on the back cover of the electronic device 10 (as shown in the smartphone). The user can input the start command EN by tapping the back cover of the electronic device 10. After receiving the start command EN, the interface layer setting unit 120 immediately displays the interface layer 210 on the screen 200 of the touch screen 12 on the front of the electronic device 10.
[0032] This interface layer 210 is located on top of the screen 200, shielding the user from touch control of other applications within the screen 200. In one embodiment, as shown in the figure, this interface layer 210 may have a control area with multiple control options 212 (only one is shown in the figure) for the user to select. These control options 212 may include, for example, options for selection, options for ending screen control, etc.
[0033] Subsequently, as described in step S240, a first touch trajectory TT1 is obtained through the interface layer 210. The first touch trajectory TT1 corresponds to a first area A1 of the screen 200. In one embodiment, this first touch trajectory TT1 is a closed trajectory with its ends connected, and the first area A1 is the area surrounded by the first touch trajectory TT1. This step can be performed by the display area setting unit 140.
[0034] Next, as described in step S260, a shielded region AS is identified based on the first region A1. This step can be performed by the interface layer state control unit 160.
[0035] Then, as described in step S280, the transparency of a portion of the interface layer 210 corresponding to the shielding region AS is changed.
[0036] Please refer to the above as well. Figure 4 , Figure 4 show Figure 2 An embodiment of steps S260 and S280.
[0037] As shown in the figure, in this embodiment, the preset state of the interface layer 210 is transparent. The interface layer state control unit 120 is adapted to change the portion of the interface layer corresponding to the shielded area AS (that is, the part outside the first area A1) from transparent to shielded, while the first area A1 remains transparent. The first area A1 contains the screen content that the user wants to share.
[0038] Secondly, the color of the masked portion of the interface layer 210 can be set according to the user's actual needs. For example, the color of the masked portion of the interface layer 210 can be black or white.
[0039] In this case, the screen display control mode can be selected by clicking on the control option 212 on the interface layer 210 to choose how to define the first area A1.
[0040] Please refer to the above as well. Figures 5A to 5C , Figures 5A to 5C This document shows three embodiments of the first area A1 defined in this case.
[0041] exist Figure 5A In the illustrated embodiment, the first touch trajectory TT1 is a closed trajectory with its ends connected. The first region A1a follows the direction of the first touch trajectory TT1 completely and is the area enclosed by the first touch trajectory TT1. This first region A1a can be any pattern.
[0042] exist Figure 5B In the illustrated embodiment, the first area A1b is preset to be square (or rectangular). The user can input a first touch trajectory TT1 via touch, and the display area setting unit 140 will form a corresponding square area as the first area A1b based on the first touch trajectory TT1.
[0043] In another embodiment, the user can further change the position or size of the first area A1b by dragging the square area (which can be understood as the first touch trajectory TT1). Specifically, the user can change the position of the first area A1b by dragging the touch points inside the square area; and can change the size and shape of the first area A1b by dragging the touch points of the outer frame of the square area.
[0044] exist Figure 5C In the illustrated embodiment, the first region A1c is preset to be circular (or elliptical). The user can input a first touch trajectory TT1 via touch. The display area setting unit 140 will form a corresponding circular region as this first region A1c based on the first touch trajectory TT1.
[0045] In another embodiment, the user can further change the position or shape of the first region A1c by dragging the circular area via touch (which can be understood as inputting the first touch trajectory TT1). Specifically, the user can change the position of the first region A1c by dragging the touch points inside the circular area; and can change the size and shape of the first region A1c by dragging the touch points on the outer frame of the circular area.
[0046] Please refer to the above as well. Figure 6 , Figure 6 show Figure 2 Another embodiment of steps S260 and S280.
[0047] In the foregoing Figure 4In the embodiment shown, the preset state of the interface layer 210 is a transparent state. The interface layer state control unit 120 identifies the area outside the first region A1 as the shielded region AS and changes the portion of the interface layer 210 corresponding to the shielded region AS (the part outside the first region A1) from the transparent state to the shielded state.
[0048] In contrast, in this embodiment, the preset state of the interface layer 210 is also transparent. However, the interface layer state control unit 120 treats the first region A1 as a shielded region AS and increases the transparency of the portion of the interface layer 210 corresponding to the first region A1, changing the portion of the interface layer 210 corresponding to the first region A1 from a transparent state to a shielded state, while the other portions of the interface layer 210 remain transparent. The first region A1 contains screen content that the user does not wish to share.
[0049] Finally, as described in step S290, in response to an end command DIS, the screen control mode is exited, and the interface layer 210 is removed. At this time, the screen 200 will return to its original unmasked state. This step can be performed by the interface layer setting unit 120.
[0050] Please refer to the above as well. Figure 7 , Figure 7 show Figure 2 An embodiment of step S290 in the process.
[0051] As shown in the figure, the control options 212 presented by the interface layer 210 may include an end option (i.e., the "X" option in the figure). The user can generate an end command DIS by clicking the end option to exit the screen control mode of this invention. However, this invention is not limited to this. In other embodiments, the user can also use the preset unlocking modes in the electronic device 10, such as password, facial recognition, fingerprint, pattern, etc., to exit the screen control mode.
[0052] Figure 8 This is a block diagram of a screen display control device 800 provided according to another embodiment of this case.
[0053] exist Figure 1 In this embodiment, the display area setting unit 140 is adapted to obtain the first touch trajectory TT1 through the interface layer 210 to define the first area A1. The interface layer state control unit 160 confirms a shielding area AS based on the first area A1 and changes the transparency of a portion of the interface layer 210 corresponding to the shielding area AS.
[0054] In contrast, the display area setting unit 840 of the screen display control device 800 in this embodiment can sequentially acquire multiple touch tracks (e.g., the first touch track TT1 and the second touch track TT2) through the interface layer 210. These touch tracks can correspond to multiple different areas (e.g., the first area A1 and the second area A2). The interface layer state control unit 860 identifies a shielded area AS based on these areas (e.g., the first area A1 and the second area A2) and changes the transparency of a portion of the interface layer 210 corresponding to the shielded area AS.
[0055] Please refer to the above as well. Figure 9 , Figure 9 This is a flowchart of a screen display control method provided according to another embodiment of this case. This screen display control method is applicable to... Figure 8 The screen display control device 800 shown. This screen display control method includes the following steps.
[0056] First, as described in step S920, in response to a startup command EN, the screen control mode is entered, and an interface layer 210 is set at the top of the screen 200. This step can be performed by the interface layer setting unit 820.
[0057] Subsequently, as described in step S940, a first touch trajectory TT1 is obtained through the interface layer 210, and the first touch trajectory TT1 corresponds to a first area A1 of the screen 200. This step can be performed by the display area setting unit 840.
[0058] Next, as described in step S950, a second touch trajectory TT2 is obtained through the interface layer 210. The second touch trajectory TT2 corresponds to a second area A2 of the screen 200. This step can be performed by the display area setting unit 840.
[0059] Then, as described in step S960, a shielding region AS is identified based on the first region A1 and the second region A2. This step can be performed by the interface layer state control unit 860.
[0060] Subsequently, as in step S980, the transparency of a portion of the interface layer 210 corresponding to the shielded region AS is changed. This step can be performed by the interface layer state control unit 860.
[0061] Finally, as described in step S990, the screen control mode is exited in response to an end command DIS, and the interface layer 210 is removed. This step can be performed by the interface layer setting unit 820.
[0062] The aforementioned steps S920 and S990 are similar Figure 2 Steps S220 and S290 are not described in detail here.
[0063] Please refer to the above as well. Figure 10 , Figure 10 show Figure 9 The first embodiment of steps S940 to S980.
[0064] In this embodiment, where the second region A2 does not overlap with the first region A1, the first region A1 and the second region A2 are regarded as two independent regions. The part of the screen 200 outside the first region A1 and the second region A2 is regarded as the shielded region AS. The transparency of the part of the interface layer 210 corresponding to the shielded region AS is increased, so that it changes from a transparent state to a shielded state.
[0065] Please refer to the above as well. Figure 11 , Figure 11 show Figure 9 The second embodiment of steps S940 to S980.
[0066] In the case where the second region A2 overlaps with the first region A1, this embodiment generates a third region A3 by extending the outer contour of the first region A1 from the second region A2. The part of the screen 200 located outside the third region A3 is regarded as the shielding region AS, and the transparency of the part of the interface layer 210 corresponding to the shielding region AS is increased, so that it changes from a transparent state to a shielding state.
[0067] The third region A3 can be considered as a combination of the first region A1 and the second region A2. This operation can be achieved using the "union" operation in Boolean operations.
[0068] The aforementioned embodiment considers the area outside the third region A3 as the shielding region AS. However, this embodiment is not limited to this. In other embodiments, the third region A3 may also be considered as the shielding region AS.
[0069] Please refer to the above as well. Figure 12 , Figure 12 show Figure 9 The third embodiment of steps S940 to S980.
[0070] When the second region A2 overlaps with the first region A1, this embodiment can generate a fourth region A4 by reducing the outer contour of the first region A1 based on the second region A2. The part of the image 200 located outside the fourth region A4 is regarded as the shielding region AS, and the transparency of the part of the interface layer 210 corresponding to the shielding region AS is increased, so that it changes from a transparent state to a shielding state.
[0071] The fourth region A4 can be considered as being formed by excluding the second region A2 from the first region A1. This operation can be achieved using the "difference" operation in Boolean operations.
[0072] The aforementioned embodiment considers the area outside the fourth region A4 as the shielding region AS. However, this embodiment is not limited to this. In other embodiments, the fourth region A4 may also be considered as the shielding region AS.
[0073] In another embodiment, the user can control the screen display control device 800 to adopt the area division method of the aforementioned embodiments by selecting control options on the interface layer 210.
[0074] It is worth noting that, in the preceding Figures 10 to 12 The embodiment described herein illustrates a screen display control method when two touch trajectories (i.e., the first touch trajectory TT1 and the second touch trajectory TT2) correspond to two different regions (i.e., the first region A1 and the second region A2), but this invention is not limited to this. The screen display control device 800 and screen display control method of this invention can also be applied to usage scenarios where more touch trajectories are acquired. For example, if three touch trajectories are acquired and three regions are divided, these three regions can be treated as independent regions to determine the parts of the interface layer 210 that require transparency adjustment. Furthermore, if these regions overlap, the union or difference of these regions can be used to determine the parts of the interface layer 210 that require transparency adjustment, according to the aforementioned principle.
[0075] Using the screen control device 100, 800 and screen control method provided in this case, users can easily and intuitively activate the interface layer 210 and input the first touch trajectory TT1 to confirm the shielded area AS. In this way, unwanted content on the screen 200 can be quickly shielded to protect personal privacy, while allowing users to share the screen 200 with peace of mind.
[0076] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes and modifications without departing from the concept and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
