According to an embodiment, the imaging unit 453 may configure a preview screen including a preview image and a virtual preview image. For example, imaging module 453 may place a preview image in at least a partial area (including the entire area) of the preview screen, and may place a virtual preview image in a partial area (e.g., a top area) of the preview screen. . The imaging module 453 may arrange the virtual preview image with the preview image overlapped. In an embodiment, the imaging module 453 may configure the preview screen with a preview image or a virtual preview image. For example, the imaging module 453 may configure the first preview screen with a preview image, and may configure the second preview screen with a virtual preview image. If there are multiple virtual preview images, there may also be multiple second preview screens.

[87] FIG. 5 illustrates a diagram for describing a method for providing an image on a preview screen related to camera selection using a camera that provides a preview image according to the embodiment.

[88] Referring to FIG. 5, the electronic device (eg, electronic device 101 or electronic device 200) may activate at step 510 the first camera (eg, first camera 231) through the camera control module 410 of the screen display module 400. The first camera has the first viewing angle and may be the camera that was last used by the user. For example, the first camera may be the camera that last provided the preview image through the display (eg, display 160 or display 250) of the electronic device. Those. the first camera may be a camera configured as a photographing camera. According to an embodiment, the first camera may have the largest viewing angle among the plurality of cameras included in the electronic device.

[89] If the first camera is activated, the electronic device can acquire the first image from the first camera through the image acquisition unit 451 of the screen display unit 400 . If the first image is received, the electronic device may display, at step 520, the received first image on a display via the image display unit 455 of the screen display unit 400 . For example, the image display unit 455 may display the first preview screen configured with the first image on the display.

[90] In step 530, the electronic device may determine whether the first input event has been generated via the input receiving module 430 of the screen rendering module 400 . For example, the input receiving module 430 may determine whether the first button input (first button input event) has been received via a physical button included in the input device (eg, input device 150), whether the first voice input (first voice input event) has been received via the microphone included in the input device, whether the first touch input (first single touch event with landing or first single touch event with tear off) was received via the display, or whether an event (multiple touch event with landing) associated with the onset was received pinch gesture input, through the display.

[91] In response to determining that the first input event has not occurred, the electronic device may return to step 520 to display the first image on the display. The electronic device may reacquire the first image from the first camera via the image acquisition module 451 and may display the reacquired first image on a display via the image display module 455.

[92] In response to determining that the first input event has occurred, the electronic device at step 540 may generate a second image by cropping the first image with the imaging module 453 of the screen display module 400, and may display the generated second image on the display via the module 455 image display. The first image may be a reference image and the second image may be a virtual preview image. The second image may include an image corresponding to a second viewing angle that is smaller than the first viewing angle. The second image may include an image (eg, an image that is not cropped) corresponding to the first viewing angle.

[93] According to an embodiment, the virtual preview image (second image) can be generated according to the number of cameras capturing images in the same or similar direction as the photographing direction of the first camera, among the plurality of cameras included in the electronic device. For example, if there are a plurality of cameras capturing images in a direction identical or similar to the photographing direction of the first camera, a plurality of virtual preview images may also be generated. The generated virtual preview images may be cropped according to the viewing angles of a plurality of cameras, respectively. For example, if cameras capturing images in the same or similar photographing direction as the photographing direction of the first camera include a camera (e.g., second camera 232) having a smaller second viewing angle than the first viewing angle and a camera (e.g., a third camera 233) having a smaller third viewing angle than the first viewing angle, the imaging unit 453 may generate a first virtual preview image by cropping the first image according to the second viewing angle, and may generate a second virtual preview image by cropping the first images according to the third viewing angle.

[94] According to an embodiment, the imaging unit 453 may configure a preview screen to be displayed on the display. For example, imaging module 453 may place at least one second image in a partial area of the first preview screen. The imaging unit 453 may place the second image with an overlap on the first image included in the first preview screen. As another example, imaging module 453 may configure at least one second preview screen using at least one second image. For example, when a plurality of second images are generated, a plurality of second preview screens may also be configured.

[95] According to an embodiment, the image display unit 455 may process the display of the second image differently according to the type of the first input event. For example, if the first input event is a button event, a voice event, or a touch input event (e.g., a single touch event with a landing or a single touch event with a lift off), the image display module 455 may display a first preview screen on which at least one second image is located in a partial area of the first preview screen. As another example, if the first input event is an event (e.g., multi-touch touch event with landing) related to the start of a pinch gesture input, the image display unit 455 may display on the display for at least one second a preview screen configured with using at least one second image. According to the distance between touched objects, when the pinch gesture is input, a second preview screen can be displayed on the display including a second image corresponding to a viewing angle that is consistent with said distance.

[96] In step 550, the electronic device may determine whether a second input event has been generated via the input receiving module 430 . For example, the input receiving module 430 may determine whether a second button input (second button input event) was received via a physical button, whether a second voice input (second voice input event) was received via a microphone, whether a second touch input was received (second single event). touch-down or second single-tap-drop event) via the display, or whether an event (simultaneous-touch-multiple-touch-and-land event) associated with the end of pinch gesture input was received via the display.

[97] In response to determining that the second input event has not occurred, the electronic device may return to step 540 to display the second image on the display. The electronic device may reacquire the first image from the first camera via the image acquisition module 451, may regenerate the second image by cropping the reacquired first image via the imaging module 453, and may display the regenerated second image on a display via the image display module 455. The method for displaying the second image may be identical or similar to the description provided at block 540.

[98] In response to determining that a second input event has occurred, the electronic device at step 560 may activate the second camera through the camera control module 410. The camera control module 410 may switch (or configure) the photographing camera from the first camera to the second camera. The second camera has a smaller viewing angle than the first viewing angle and may be a camera selected by the user from the plurality of cameras. For example, if the second touch input occurred at the display position of the first virtual preview image, the second camera may be a camera (eg, the second camera 232) having a second viewing angle, and if the second touch input occurred at the display position of the second virtual preview image, view, the second camera may be a camera (eg, the third camera 233) having a third viewing angle. As another example, when the distance between touch objects is the first distance, if the pinch gesture input ends, the second camera is a camera (for example, the second camera 232) having a second viewing angle, and when the distance between touch objects is the second distance, if the gesture input pinch ends, the second camera may be a camera (eg, third camera 233) having a third viewing angle.

[99] If the second camera is activated, the electronic device can acquire a third image from the second camera through the module 451 image acquisition. If the third image is received, the electronic device at step 570 may display the received third image on the display via the image display module 455 . For example, the image display unit 455 may display a third preview screen configured with the third image on the display.

[100] According to an embodiment, if the camera selected by the user from the plurality of cameras is the first camera, the electronic device may skip step 560 and step 570 and return to step 520 and may display the first image on the display. At this time, the first image may be reacquired.

[101] According to an embodiment, at step 560, the electronic device may deactivate the first camera. For example, the electronic device may deactivate a first camera configured as a photographing camera and may configure a second camera as a photographing camera when the second camera is activated. In some embodiments, the electronic device may switch the first camera to an idle state instead of deactivating the first camera.

If the second image is obtained, the electronic device in step 650 may generate a third image by cropping the second image with the imaging unit 453 of the screen display unit 400, and may display the generated third image on a display through the image display unit 455. The second image may be a reference image and the third image may be a virtual preview image. For example, the third image may include an image corresponding to a first viewing angle and a third viewing angle that are smaller than the second viewing angle. The third image may include an image (eg, an image that is not cropped) corresponding to the second viewing angle. The method for displaying the third image may be identical or similar to the description provided at step 540 of FIG. 5.

[108] In step 660, the electronic device may determine whether a second input event has been generated via the input receiving module 430 .

The camera control module 410 may switch (or configure) the photographing camera from the first camera to the third camera. The third camera has a smaller viewing angle than the second viewing angle and may be a camera selected by the user from the plurality of cameras.

[110] If the third camera is activated, the electronic device can acquire the fourth image from the third camera through the module 451 image acquisition. If the fourth image has been received, the electronic device may, at step 680, display the received fourth image on a display via the image display module 455 .

[111] According to an embodiment, if the camera selected by the user from the plurality of cameras is the first camera, the electronic device may skip step 670 and step 680 and return to step 620 and may display the first image on the display. At this time, the first image may be reacquired.

[112] According to an embodiment, if the camera selected by the user from the plurality of cameras is the second camera, the electronic device may skip step 670 and step 680 and may display the second image obtained from the second camera on the display. At this time, the second image may be reacquired.

[113] According to an embodiment, at 670, the electronic device may deactivate at least one of the first camera and the second camera. For example, the electronic device may deactivate the first camera configured as the photographing camera and may configure the third camera as the photographing camera while activating the third camera. In some embodiments, the electronic device may switch at least one of the first camera and the second camera to an idle state instead of deactivating them.

[114] FIG. 7 illustrates a diagram for describing activation times of a camera that provides a preview image and a camera that configures a preview screen according to an embodiment. In FIG. 7 describes steps identical or similar to those in FIG. 5 and FIG. 6 may be omitted.

For example, the electronic device may deactivate the first camera configured as the photographing camera and may configure the third camera as the photographing camera when the third camera is activated. In some embodiments, the electronic device may switch at least one of the first camera and the second camera to an idle state instead of deactivating them.

[126] FIG. 8 illustrates a diagram for describing a method for configuring a preview screen related to camera selection using a plurality of cameras according to an embodiment. In FIG. 8, a case will be described in which an electronic device (eg, electronic device 101 or electronic device 200) configures a plurality of cameras that acquire a reference image.

[127] Referring to FIG. 8, in step 810, the electronic device may acquire a first image from a first camera (for example, the first camera 231) having a first viewing angle through the image acquisition unit 451 of the screen image providing unit 400, and may acquire a second image from a second camera (for example, second camera 232) having a second viewing angle that is smaller than the first viewing angle.

[128] In step 820, the electronic device may determine whether the third viewing angle of the third camera is greater than the second viewing angle of the second camera via the imaging module 453 of the screen display module 400 . For example, the imaging module 453 may determine whether the third viewing angle is smaller than the first viewing angle and whether it is larger than the second viewing angle.

[129] In response to determining that the third viewing angle is greater than the second viewing angle (e.g., first viewing angle > third viewing angle > second viewing angle), the electronic device may generate a third image in step 830 by cropping the first image according to the third viewing angle, through the imaging module 453, and can display the generated third image on a display (for example, the display device 160 or the display 250) via the image display module 455 of the screen display module 400 . The first image may be a reference image and the third image may be a virtual preview image.

[130] In response to determining that the third viewing angle does not exceed the second viewing angle (e.g., first viewing angle > second viewing angle > third viewing angle), the electronic device at step 840 may generate a third image by cropping the second image in accordance with the third viewing angle through the imaging unit 453, and can display the generated third image on the display through the image display unit 455 of the screen display unit 400 . The second image may be a reference image and the third image may be a virtual preview image.

[131] According to an embodiment, when a preview screen image related to camera selection is provided, if a plurality of reference images are used, the imaging unit 453 generates a virtual preview image corresponding to a certain viewing angle using a reference image corresponding to the viewing angle close (relatively small difference in viewing angles) to a specific viewing angle from among the reference pictures corresponding to a viewing angle larger than the specific viewing angle in order to reduce the loss in image quality. For example, at step 840 of FIG. 8, if the third viewing angle is smaller than the first viewing angle and the second viewing angle, a third image can be formed by cropping the first image that corresponds to the first viewing angle according to the third viewing angle. However, since the second viewing angle is larger than the third viewing angle, and closer to the third viewing angle than to the first viewing angle (the value of the difference between the second viewing angle and the third viewing angle is less than the difference between the first viewing angle and the third viewing angle), the third image, formed by cropping the second image according to the third viewing angle may be better in terms of image quality compared to the third image generated by cropping the first image according to the third viewing angle.

The pinch gesture input 1120 may be the input, by pressing two dots on a display screen using touch objects (eg, two fingers), from moving the touch objects a predetermined distance and then releasing them. For example, the input receiving module 430 may receive a first input event at a time when touch objects are touching the display screen. The pinch gesture input can be divided into pinch input and pinch input according to the direction in which touch objects are moved. In FIG. 11 shows, as in the first state 1101, a state in which pinch input 1120 is performed with a spread in which touched objects move away from each other.
