Abstract: According to various embodiments, an electronic device includes an image sensor, a memory, and a processor. The processor is configured to control the electronic device to: obtain a plurality of image frames including external light and an external object at a first designated frame rate using the image sensor, based on a capturing signal; identify a frequency of a flicker related to the external light source; generate first section images for at least a part of a time for which the plurality of image frames are obtained using frames selected from the plurality of image frames corresponding to a second designated frame rate based at least on the frequency, the second designated frame rate being lower than the first designated frame rate; generate second section images for at least a part of the time for which the plurality of image frames are obtained in response at least to a designated input using image frames obtained at the first designated frame rate after the designated input from among the plurality of image frames; and generate moving image data including at least the first section images and the second section images.

Abstract: An electronic device is provided and includes an image sensor including a first unit pixel including a first micro-lens and a plurality of first photodiodes facing each other with a first color filter interposed between the plurality of first photodiodes, and a second unit pixel including a second micro-lens and a plurality of second photodiodes facing each other with a second color filter interposed between the plurality of second photodiodes, a camera module including the image sensor, and a processor operatively connected with the image sensor. The first unit pixel includes a first photodiode, a second photodiode, a third photodiode, and a fourth photodiode, which are disposed in a square shape such that a horizontal number of photodiodes is identical to a vertical number of photodiodes. The second unit pixel includes a fifth photodiode, a sixth photodiode, a seventh photodiode, and an eighth photodiode, which are disposed in a square shape such that a horizontal number of photodiodes is identical to a vertical number of photodiodes. The image sensor identifies an operation setting and an external environmental condition of the camera module and, upon identifying that the operation setting is a preview mode and the external environmental condition is a high luminous environment, identifies a first area signal corresponding to a signal of the first photodiode and the second photodiode, which are concatenated with each other and included in the first unit pixel, and identifies a second area signal that corresponds to a signal of the fifth photodiode, included in the second unit pixel, corresponding to a location of the first photodiode and the sixth photodiode, included in the second unit pixel, corresponding to a location of the second photodiode, and forms first auto focus (AF) information based on the first area signal and the second area signal.

Abstract: Methods and apparatuses are provided in which a first image frame is obtained by exposing and reading out a first plurality of pixels corresponding to a first region of interest (ROI) via a first image sensor. While the first image frame is being obtained, a control signal is obtained for changing the first ROI to a second ROI based on an image frame obtained from the second image sensor. In response to the obtained control signal, a second image frame continuous from the first image frame is obtained by exposing and reading out a second plurality of pixels corresponding to the second ROI via the first image sensor.
