Abstract

An electronic device including a camera and an operation method of the electronic device are provided. The electronic device includes display circuitry, a camera disposed on a rear surface of the display circuitry, a memory, and at least one processor electrically connected to the display circuitry, the camera, and the memory and being configured to identify camera driving information set for the camera, identify a shutter speed included in the set camera driving information, change set display driving information such that a time of a non-emission interval of the duty cycle of the display circuitry is greater than the shutter speed, and based on the changed display driving information, control a driving of the camera.

First claim

What is claimed is:

1 . An electronic device comprising:
display circuitry; a camera disposed on a rear surface of the display circuitry; memory storing instructions; and at least one processor including processing circuitry, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
identify camera driving information set with regard to the camera,
identify a shutter speed included in the set camera driving information,
identify, based on the identified shutter speed, whether to change set display driving information,
based on a value of the shutter speed being greater than a value of a time of a non-light-emitting interval of a duty cycle of the display circuitry, change at least one of a screen refresh rate, a duty cycle or a duty ratio included in the set display driving information, and
based on the shutter speed, control a driving of the camera within the time of the non-light-emitting interval that has been changed to a value greater than the value of the shutter speed in response to the change in at least one of the screen refresh rate, the duty cycle or the duty ratio.

2 . The electronic device of claim 1 ,
wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
set an image capture timing of the camera within the changed time of the non-light-emitting interval or change the set image capture timing, and
provide a synchronization signal for synchronization between the display circuitry and the camera to each of the display circuitry and the camera to start image capturing of the camera at the image capture timing within the non-light-emitting interval, and
wherein the synchronization signal is generated based on information regarding the time of the non-light-emitting interval and the image capture timing.

3 . The electronic device of claim 1 ,
wherein the camera driving information comprises the shutter speed, wherein the display driving information comprises at least one of a refresh rate, a duty cycle, or a duty ratio, wherein, whether to change the set display driving information, is identified additionally based on the time of the non-light-emitting interval, and wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
control the camera to be driven based on the identified shutter speed within the time of the non-light-emitting interval changed according to the changed display driving information, and
control the camera not to be driven during a time of a duty cycle light-emitting interval.

4 . The electronic device of claim 3 ,
wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
based on the value of the shutter speed being greater than the value of the time of the non-light-emitting interval of the duty cycle of the display circuitry, change at least one of the refresh rate or the duty ratio included in the set display driving information such that the value of the time of the non-light-emitting interval is larger than the value of the identified shutter speed, and
wherein the time of the non-light-emitting interval is changed according to a change in the refresh rate or a change in the duty ratio.

5 . The electronic device of claim 3 , wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
based on the value of the shutter speed being less than or equal to the value of the time of the non-light-emitting interval of the duty cycle of the display circuitry, maintain the set display driving information, and based on the set display driving information, control the driving of the camera based on the shutter speed within the time of the non-light-emitting interval.

6 . The electronic device of claim 1 , further comprising:
a display, wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
change a refresh rate of pixels of a pixel line in a first region of the display corresponding to a region in which the camera is disposed, and
maintain the refresh rate of pixels of a remaining region excluding the first region to be a refresh rate included in the set display driving information.

7 . The electronic device of claim 1 , further comprising:
a display, wherein the instructions, when executed by the at least one processor, individually or collectively further cause the electronic device to:
control pixels in a first region of the display corresponding to a region in which the camera is disposed at a timepoint at which an image is captured and a second region comprising a peripheral region of the first region as black such that the pixels in the first region and the second region do not emit light, and
maintain display driving information of pixels in a remaining region excluding the second region to be the set display driving information.

8 . The electronic device of claim 1 ,
wherein the camera comprises an under display camera (UDC), wherein at least a part of the camera is disposed under a display panel of the display circuitry, and wherein the camera is disposed between the display panel and a substrate.

9 . The electronic device of claim 1 , wherein the instructions, when executed by the at least one processor individually or collectively, further cause the electronic device to:
change the identified shutter speed included in the set camera driving information to be identical to or smaller than an off-duty time to prevent an occurrence of light interference of the display circuitry during an on-duty time.

10 . The electronic device of claim 9 , wherein the instructions, when executed by the at least one processor, further cause the electronic device to:
based on the identified shutter speed, control both the on-duty time and the off-duty time of the duty cycle corresponding to an image capture timing as black such that no light is emitted during the on-duty time and the off-duty time.

11 . A method performed by an electronic device, the method comprising:
identifying camera driving information set with regard to a camera disposed on a rear surface of display circuitry of the electronic device; identifying a shutter speed included in the set camera driving information; identifying, based on the identified shutter speed, whether to change set display driving information; based on a value of the shutter speed being greater than a value of a time of a non-light-emitting interval of a duty cycle of the display circuitry, changing at least one of a screen refresh rate, a duty cycle or a duty ratio included in the set display driving information; and based on the shutter speed, controlling a driving of the camera within the time of the non-light-emitting interval that has been changed to a value greater than the value of the shutter speed in response to the change in at least one of the screen refresh rate, the duty cycle or the duty ratio.

12 . The method of claim 11 , further comprising:
setting an image capture timing of the camera within the changed time of the non-light-emitting interval or changing the set image capture timing; and providing a synchronization signal for synchronization between the display circuitry and the camera to each of the display circuitry and the camera to start image capturing of the camera at the image capture timing within the non-light-emitting interval
