Electronic device for capturing high dynamic range images, and operating method thereof

1 . An electronic device, comprising:

a camera apparatus;

a display;

at least one processor; and

memory storing instructions, that, when executed by the at least one processor, cause the electronic device to:

obtain, through the camera apparatus, a first image and at least one image in which a parameter for a high dynamic range (HDR) is changed with respect to the first image;

obtain a first HDR image using the first image and the at least one image;

display, on the display, a first preview image corresponding to the first image and a second preview image corresponding to the first HDR image;

while displaying the first preview image and the second preview image, display, on the display, a user interface for changing at least one of an exposure value, white balance, shutter speed, or ISO sensitivity of the first HDR image; and

based on identifying a user input to the user interface while the first preview image and the second preview image are being displayed, display the second preview image, which is generated based on the at least one of the exposure value, white balance, shutter speed, or ISO sensitivity changed by the user input, as the second preview image in place of the first preview image.

2 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to display the first preview image and the second preview image overlapping.

3 . The electronic device of claim 2 , wherein the instructions, when executed by the at least one processor, cause the electronic device to display the second preview image in a smaller size than the first preview image.

4 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:

obtain an image corresponding to the first image through a first camera included in the camera apparatus; and

obtain the first image and the at least one image through a second camera included in the camera apparatus.

5 . The electronic device of claim 4 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:

obtain the image corresponding to the first image in a first time period through the first camera; and

obtain the first image in the first time period and the at least one image in a second time period different from the first time period, through the second camera.

6 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to obtain the first image in a first time period and the at least one image in a second time period different from the first time period, through any camera included in the camera apparatus.

7 . The electronic device of claim 6 , wherein the instructions, when executed by the at least one processor, cause the electronic device to:

resize the first image and the at least one image obtained through the any camera; and

obtain the first HDR image using the resized first image and the resized at least one image.

8 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to obtain the first HDR image using at least two of the first image, a second image in which an exposure degree is increased by a second exposure value with respect to the first image, and a third image in which the exposure degree is decreased by the second exposure value with respect to the first image.

9 . The electronic device of claim 8 , wherein the instructions, when executed by the at least one processor, cause the electronic device to, based on the exposure degree being changed into a third exposure value in response to the user input, obtain the second image using at least two of the first image, a fourth image in which the exposure degree is increased by the third exposure value with respect to the first image, and a fifth image in which the exposure degree is decreased by the third exposure value with respect to the first image.

10 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor, cause the electronic device to capture an image based on the second preview image through the camera apparatus, based on a user input requesting to capture an HDR image.

11 . A method for operating an electronic device, the method comprising:

obtaining, through a camera apparatus included in the electronic device, a first image and at least one image in which a parameter for a high dynamic range (HDR) is changed with respect to the first image;

obtaining a first HDR image using the first image and the at least one image;

displaying, on a display included in the electronic device, a first preview image corresponding to the first image and a second preview image corresponding to the first HDR image;

while displaying the first preview image and the second preview image, displaying, on the display, a user interface for changing at least one of an exposure value, white balance, shutter speed, or ISO sensitivity of the first HDR image; and

based on identifying a user input to the user interface while the first preview image and the second preview image are being displayed, displaying the second preview image, which is generated based on the at least one of an exposure value, white balance, shutter speed, or ISO sensitivity changed by the user input, as the second preview image in place of the first preview image.

12 . The method of claim 11 , wherein displaying the first preview image and the second preview image includes displaying the first preview image and the second preview image overlapping.

13 . The method of claim 11 , wherein displaying the first preview image and the second preview image includes displaying the second preview image in a smaller size than the first preview image.

14 . The method of claim 11 , wherein obtaining the first image and the at least one image includes:

obtaining an image corresponding to the first image through a first camera included in the camera apparatus; and

obtaining the first image and the at least one image through a second camera included in the camera apparatus.

15 . The method of claim 14 , wherein obtaining the first image and the at least one image includes:

obtaining the image corresponding to the first image in a first time period through the first camera; and

obtaining the first image in the first time period and the at least one image in a second time period different from the first time period, through the second camera.
