For example, the display unit 102 can be a display panel of the electronic device 100. The photographing unit 104 may be a camera mounted on the electronic device 100. The processing circuit can be a central processor of the electronic device. The input unit 108 can be a touch panel of the electronic device 100 or other component having an instruction input function. The memory unit 110 can be a memory in the electronic device 100. In some embodiments, display unit 102 and input unit 108 can be integrated into a single component (eg, a touch display panel).

The electronic device 100 is used to simulate the field of view of a photographing device. In this way, the user can know the imaging field of view of the imaging device in advance through the electronic device 100 when the imaging device has not been mounted. In some embodiments, the photographic device is an IP camera.

FIG. 2 is a schematic diagram of the appearance of an electronic device 100 according to an embodiment of the disclosure. The user can install a specific application software (application; APP) on the electronic device 100 in advance to simulate the shooting field of the photographing device by using the application software. As shown in FIG. 2, when the application software installed on the electronic device 100 is turned on, the corresponding user interface is displayed on the display unit 102. The user interface includes at least a pull-down menu 1022 and an image display area 1026. In some embodiments, the user interface further includes another pull down menu 1024.

When the application software is turned on, the photographing unit 104 of the electronic device 100 is simultaneously turned on. At this time, if the user points the photographing unit 104 toward a specific scene (not photographed), the image of the specific scene will be displayed on the image display. Area 1026 is shown. That is to say, the image on the image display area 1026 changes depending on the position of the user and the facing direction of the photographing unit 104.

The drop down menu 1022 contains a plurality of options. These options correspond to different photographic devices, respectively. In other words, the user can select the brand, model or combination of the photographic device to be simulated through the pull-down menu 1022.

The drop down menu 1024 contains a plurality of options. These options correspond to different lenses. In other words, in addition to selecting the photographic device to be simulated through the pull-down menu 1022, the user can also select the lens that is matched with the photographic device through the pull-down menu 1024. For example, the user can select a lens with different focal lengths through the pull-down menu 1024. The focal length is, for example, 14 mm or 20 mm, but the disclosure is not limited thereto. Since different focal lengths will affect the size of the field of view, when the user selects a lens with a different focal length, the corresponding field of view size may change.

In other embodiments, the drop down menu 1022 includes a plurality of options. These options correspond to the fields of view of different photographic devices, respectively. In other words, the user can select the size of the field of view of the imaging device to be simulated through the pull-down menu 1022, for example, 1080p, 720p or 4K, but not limited thereto.

Next, please refer to Figure 1 and Figure 2 together. When the user operates the input unit 108 to select the imaging device to be simulated through the pull-down menu 1022, the input unit 108 transmits the selection signal D1 to the processing circuit 106. The selection signal D1 corresponds to the photographing device selected by the user. If the user selects the photographing device to be simulated through the pull-down menu 1022 and selects the lens of the specific focal length through the pull-down menu 1024, the selection signal D1 corresponds to the photographing device selected by the user and the lens of the selected specific focal length.

Then, after the processing circuit 106 receives the selection signal D1, if the selection signal D1 corresponds to the camera device selected by the user, the processing circuit 106 can search the database 200 according to the selection signal D1 to search for the selected one from the database 200. The field of view V1 of the photographing device (hereinafter referred to as the first field of view). If the selection signal D1 corresponds to the camera selected by the user and the lens of the selected specific focal length, the processing circuit 106 can search the database 200 for the field of view V1 after the selected camera is matched with the selected lens according to the selection signal D1. The database 200 can be a server of a manufacturer of the photographic device or another storage device that stores the field of view V1.

The field of view V2 of the photographing unit 104 (hereinafter referred to as a second field of view) may be stored in the memory unit 110 in advance. When the application software is turned on, the second field of view V2 is transmitted to the processing circuit 106. The field of view V2 of the photographing unit 104 is the field of view V2 of the image acquired by the photographing unit 104.

The processing circuit 106 compares the field of view V1 of the selected imaging device with the field of view V2 of the image to produce a field of view comparison result. In some embodiments, the field of view V1 and the field of view V2 are each a value, so the processing circuit 106 can compare the value of the field of view V1 with the value of the field of view V2.

Next, the processing circuit 106 controls the display unit 102 to display the image acquired by the photographing unit 104 and the simulated photographing field of the selected photographing device based on the visual field comparison result. This section will be detailed below.

FIG. 3 is a schematic diagram of an image display area 1026 of the electronic device 100 according to an embodiment of the present disclosure. When the field of view comparison result is that the first field of view V1 is smaller than the second field of view V2, the field of view V1 representing the selected imaging device is smaller than the field of view V2 of the imaging unit 104 of the electronic device 100. at this time, The processing circuit 106 controls the display unit 102 to simultaneously display the image P1 and the frame line F1 acquired by the photographing unit 104 on the image display area 1026 in accordance with the field of view comparison result. Further, the processing circuit 106 has the area framed by the control frame line F1 smaller than the area of the image P1. That is to say, the image P1 is separated by the frame line F1 from the frame inner area A11 and the frame outer area A12. The frame inner area A11 is the simulated field of view of the selected photographing device. In this way, the user can know that when the photographing device is located at the position of the electronic device 100, the photographing field that the photographing device can capture is smaller than the photographing field of the electronic device 100 by viewing the image display area 1026.

In this way, the user can know the shooting field of view when the photographing device is located at the position of the electronic device 100 by looking at the image display area 1026. By the above method, the user can select an appropriate photographic device according to his needs, so as to avoid that the photographic device does not meet the user's needs until the photographic device is installed. Further, by the above-described method, since the user can move while holding the electronic device 100, the convenience and mobility of the simulation process can be improved.

FIG. 4 is a schematic diagram of an image display area 1026 of the electronic device 100 according to an embodiment of the present disclosure. Figure 4 is similar to Figure 3. In brief, when the first field of view V1 is smaller than the second field of view V2, the image P2 is separated by the frame line F2 from the frame inner area A21 and the frame outer area A22. The frame inner area A21 is the simulated photographing field of the selected photographing device.

In some embodiments, in order to make the frame inner region A21 more easily recognized by the user, the processing circuit 106 can control the transparency of the frame inner region A21 and the transparency of the frame outer region A22 to be different. In other words It can be said that the transparency of the image located in the outer area A22 of the frame line can be higher than the transparency of the image located in the inner area A21 of the frame line. Alternatively, the transparency of the image located in the outer area A22 of the frame line may be lower than the transparency of the image located in the inner area A21 of the frame line.

In some other embodiments, in order to make the frame inner area A21 more easily recognized by the user, the processing circuit 106 may control the brightness of the frame inner area A21 and the brightness of the frame outer area A22 to be different. In other words, the brightness of the image located in the outer area A22 of the frame line may be higher than the brightness of the image located in the inner area A21 of the frame line. Alternatively, the brightness of the image located in the outer area A22 of the frame line may be lower than the brightness of the image located in the inner area A21 of the frame line.

It should be particularly noted that the thick lines and thin lines drawn in FIG. 4 are used to indicate that the two areas (the frame inner area A21 and the frame outer area A22) have different transparency or brightness.

FIG. 5 is a schematic diagram of an image display area 1026 of an electronic device 100 according to an embodiment of the present disclosure. In some embodiments, when the field of view comparison result is that the first field of view V1 is greater than the second field of view V2, the field of view V1 representing the selected camera device is greater than the field of view V2 of the camera unit 104. At this time, the processing circuit 106 controls the display unit 102 to simultaneously display the image P3 and the frame line F3 on the image display area 1026 according to the field of view comparison result. The frame line F3 is the boundary of the image display area 1026. The frame line F3 corresponds to the simulated field of view of the selected camera device.

Since the field of view V2 of the photographing unit 104 is smaller than the field of view V1 of the photographing device, the processing circuit 106 correspondingly reduces the image to be displayed, and controls the display unit 102 to display the reduced image P3, so that the image is displayed. P3 is located inside the frame line F3.

In addition, the processing circuit 106 controls the display unit 102 to display a black area B between the frame line F3 and the image P3. The black area B is used to represent a field of view that the photographing apparatus can photograph and that the photographing unit 104 cannot capture. In this way, the user can know by viewing the image display area 1026 that when the photographing device is located at the position of the electronic device 100, the photographing field that the photographing device can capture is larger than the photographing field of the electronic device 100.

Please also refer to Figures 3 to 5. In some embodiments, the processing circuit 106 controls the display unit 102 to display that the center point C1 of the image is aligned with the center point C2 of the frame line. It should be noted that, in some other embodiments, the processing circuit 106 can control the display unit 102 to display that the center point C1 of the image is not aligned with the center point C2 of the frame line.

In the first diagram, in step S602, an image is acquired by the photographing unit 104 of the electronic device 100. In step S604, the first field of view V1 corresponding to the photographing device is received by the electronic device 100. In step S606, the second field of view V2 of the image and the first field of view V1 are compared by the electronic device 100 to generate a field of view comparison result. In step S608, the electronic device 100 simultaneously displays the image and a simulated shooting field corresponding to the photographing device according to the field of view comparison result.

The above examples include sequential steps, but the steps are not It must be executed in the order shown. Performing these steps in a different order is within the scope of this case. In addition, within the spirit and scope of the embodiments of the present disclosure, the steps may be added, replaced, changed, and/or omitted as appropriate.
