Abstract

An electronic device according to various embodiments comprises a camera module, a communication module, and a processor electrically connected to the camera module and the communication module, wherein the processor acquires an exposure value for an image inputted using the camera module, acquires lighting control-related information from at least one lighting device on the basis of a network connected using the communication module, and can generate a signal for adjusting at least one piece of the lighting control-related information of the at least one lighting device on the basis of the exposure value and a preset lighting control-related information set value. In addition, other embodiments are possible.

First claim

The invention claimed is:

1. An electronic device comprising:
a camera module;
a display;
a communication module; and
a processor electrically connected with the camera module, the display and the communication module,
wherein the processor is configured to:
control the display to display a preview image inputted through the camera module;
obtain an exposure value for the preview image;
obtain lighting control-related information from at least one lighting device through a network connected by using the communication module;
control the display to display the lighting control-related information obtained from the at least one lighting device, in response to identifying that a face is detected from the preview image;
in response to a selection of a lighting effect, control the display to display the preview image to which an image effect corresponding to the selected lighting effect is applied; and
generate a signal for adjusting at least one piece of the lighting control-related information of the at least one lighting device based on the exposure value and a preset lighting control-related information setting value corresponding to the selected lighting effect, in response to a photographing signal input.

2. The electronic device of claim 1 , wherein the lighting control-related information of the at least one lighting device includes an active state of the at least one lighting device, an inactive state of the at least one lighting device, position information of the at least one lighting device, a direction the at least one lighting device faces, an amount of light of the at least one lighting device, a color of the at least one lighting device, or a color temperature of the at least one lighting device.

3. The electronic device of claim 1 , wherein the lighting control-related information setting value includes information about whether the at least one lighting device is activated or deactivated, a position value of the at least one lighting device, a direction the at least one lighting device faces, a light amount value of the at least one lighting device, a color value of the at least one lighting device, or a color temperature value of the at least one lighting device.

4. The electronic device of claim 1 , wherein the processor is configured to:
control the display to display lighting control-related information of a lighting device located within a preset distance from the electronic device, and
control the display to display the lighting control-related information of the lighting device located within the preset distance to be included in the preview image.

5. The electronic device of claim 1 , wherein the processor is configured to:
control the display to display icons indicating a position and a direction of a lighting device located within a preset distance from the electronic device and the lighting control-related information of the lighting device located within the preset distance, when the lighting device located within the preset distance is not directly displayed in a photographic viewing angle (composition) of the camera module.

6. The electronic device of claim 1 , wherein the processor is configured to:
after capturing an image based on the photographing signal input,
generate a signal for changing the adjusted at least one piece of the lighting control-related information into the at least one piece of the lighting control-related information in a state previous to the adjustment.

7. The electronic device of claim 1 , wherein the processor is configured to:
after capturing an image based on the photographing signal input,
generate a signal for maintaining the adjusted lighting control-related information.

8. The electronic device of claim 1 , wherein the processor is further configured to control the display to display a lighting effect icon in response to identifying that the face is detected from the image.

9. A control method of an electronic device comprising a
display, a camera module and a communication module, the control method comprising:
displaying, on the display, a preview image inputted through the camera module obtaining an exposure value for the preview image;
obtaining lighting control-related information from at least one lighting device by using the communication module;
displaying, on the display, the lighting control-related information obtained from the at least one lighting device, in response to identifying that a face is detected from the preview image;
in response to a selection of a lighting effect, displaying, on the display, the preview image to which an image effect corresponding to the selected lighting effect is applied; and
generating a signal for adjusting at least one piece of the lighting control-related information of the at least one lighting device based on the exposure value and a preset lighting control-related information setting value corresponding to the selected lighting effect, in response to a photographing signal input.

10. The control method of claim 9 , wherein the lighting control-related information of the at least one lighting device includes an active state of the at least one lighting device, an inactive state of the at least one lighting device, position information of the at least one lighting device, a direction the at least one lighting device faces, an amount of light of the at least one lighting device, a color of the at least one lighting device, or a color temperature of the at least one lighting device.

11. The control method of claim 9 , wherein the lighting control-related information setting value includes information about whether the at least one lighting device is activated or deactivated, a position value of the at least one lighting device, a direction the at least one lighting device faces, a light amount value of the at least one lighting device, a color value of the at least one lighting device, or a color temperature value of the at least one lighting device.

12. The control method of claim 9 , further comprising displaying, on the display, lighting control-related information of a lighting device located within a preset distance from the electronic device to be included in the preview image.

13. The control method of claim 9 , further comprising displaying, on the display, icons indicating a position and a direction of a lighting device located within a preset distance from the electronic device and the lighting control-related information of the lighting device located within the preset distance.
