The electronic make-up mirror device includes a screen, an image capturing device and a gesture sensor. The method includes following steps. An initial image is captured by using the image capturing device, and an initial frame including the initial image is displayed through the screen. The initial image is analyzed to obtain a foreground object and a background image, where the foreground object includes a face image. A background selection frame is displayed through the screen in response to a first operation according to whether the first operation performed to the initial frame is received. The foreground object and a predetermined background image are integrated in response to reception of a second operation performed to the background selection frame, so as to generate an integrated image, and a switched result frame including the integrated image is displayed. ## Claims ### Claim 1 A background switching method, adapted to an electronic make-up mirror device, wherein the electronic make-up mirror device comprises a screen, an image capturing device and a gesture sensor, the background switching method comprising: capturing an initial image by using the image capturing device, and displaying an initial frame including the initial image through the screen; analyzing the initial image to obtain a foreground object and a background image, wherein the foreground object comprises a face image; displaying a background selection frame through the screen in response to a first operation according to whether the first operation performed to the initial frame is received; and integrating the foreground object and a predetermined background image in response to reception of a second operation performed to the background selection frame, so as to generate an integrated image, and displaying a switched result frame comprising the integrated image through the screen. ### Claim 2 (depends on 1) The background switching method as claimed in claim 1, wherein the first operation comprises: identifying first gesture information according to whether the gesture sensor acquires the first gesture information; and generating a first input instruction when the first gesture information is complied with a first predetermined gesture, such that the screen displays the background selection frame. ### Claim 3 (depends on 1) The background switching method as claimed in claim 1, wherein the second operation comprises: identifying second gesture information according to whether the gesture sensor acquires the second gesture information; and generating a second input instruction when the second gesture information is complied with a second predetermined gesture, so as to execute a background selection function. ### Claim 4 (depends on 3) The background switching method as claimed in claim 3, wherein the second operation further comprises: identifying third gesture information according to whether the gesture sensor acquires the third gesture information; and generating a third input instruction when the third gesture information is complied with a third predetermined gesture, and confirming a selection result of the background selection function to determine the predetermined background image. ### Claim 5 (depends on 4) The background switching method as claimed in claim 4, wherein the second operation further comprises: identifying fourth gesture information according to whether the gesture sensor acquires the fourth gesture information; and generating a fourth input instruction when the fourth gesture information is complied with a fourth predetermined gesture, ending the background selection function, and displaying the switched result frame through the screen. ### Claim 6 (depends on 1) The background switching method as claimed in claim 1, wherein the step of analyzing the initial image to obtain the foreground object and the background image comprises: analyzing the initial image according to a Gaussian mixture model, so as to obtain the foreground object and the background image. ### Claim 7 (depends on 1) The background switching method as claimed in claim 1, wherein the step of analyzing the initial image to obtain the foreground object and the background image comprises: determining a position of the face image in the initial image to determine a contour, and distinguishing the foreground object and the background image in the initial image according to the contour. ### Claim 8 An electronic make-up mirror device, comprising: a screen; a processor, coupled to the screen; and an image capturing device, coupled to the processor, configured to capture an initial image, and displaying an initial frame comprising the initial image through the screen, wherein the processor analyzes the initial image to obtain a foreground object and a background image, and the foreground object comprises a face image, wherein the processor displays a background selection frame through the screen in response to a first operation according to whether the first operation performed to the initial frame is received, wherein the processor integrates the foreground object and a predetermined background image in response to reception of a second operation performed to the background selection frame, so as to generate an integrated image, and displays a switched result frame comprising the integrated image through the screen. ### Claim 9 (depends on 8) The electronic make-up mirror device as claimed in claim 8, further comprising: a gesture sensor, wherein the first operation refers to that the processor identifies first gesture information according to whether the gesture sensor acquires the first gesture information, and generates a first input instruction when the first gesture information is complied with a first predetermined gesture, such that the screen displays the background selection frame. ### Claim 10 (depends on 8) The electronic make-up mirror device as claimed in claim 8, wherein the second operation refers to that the processor identifies second gesture information according to whether the gesture sensor acquires the second gesture information, and generates a second input instruction when the second gesture information is complied with a second predetermined gesture, so as to execute a background selection function. ### Claim 11 (depends on 10) The electronic make-up mirror device as claimed in claim 10, wherein the second operation further refers to that the processor identifies third gesture information according to whether the gesture sensor acquires the third gesture information, and generates a third input instruction when the third gesture information is complied with a third predetermined gesture, so as to confirm a selection result of the background selection function, and determine the predetermined background image. ### Claim 12 (depends on 11) The electronic make-up mirror device as claimed in claim 11, wherein the second operation further refers to that the processor identifies fourth gesture information according to whether the gesture sensor acquires the fourth gesture information, and generates a fourth input instruction when the fourth gesture information is complied with a fourth predetermined gesture, so as to ends the background selection function, and display the switched result frame through the screen. ### Claim 13 (depends on 8) The electronic make-up mirror device as claimed in claim 8, wherein the processor analyzes the initial image according to a Gaussian mixture model, so as to obtain the foreground object and the background image. ### Claim 14 (depends on 8) The electronic make-up mirror device as claimed in claim 8, wherein the processor determines a position of the face image in the initial image to determine a contour, and distinguishes the foreground object and the background image in the initial image according to the contour.
