Abstract: The present disclosure relates to an electronic device. The electronic device may comprise an image sensor and a processor connected to the image sensor electrically. The processor can generate a first image based on an electric signal generated by the image sensor. A first contrast value for the first image is calculated. A brightness value of the brightest point in a first area centered at a first point included in the first image is stored as a brightness value of the first point. A second image is generated based on the stored brightness values a weighted value is determined for each point according to the brightness value of each point included in the second image. A second contrast value is calculated based on the determined weighted value of each point and the first contrast value.

Abstract: An electronic device of an embodiment of the present document may include a camera including a lens assembly, at least one sensor configured to detect a movement of the camera or the lens assembly, and a processor electrically connected to the camera and the at least one sensor. The processor may determine an exposure value that will be applied when photographing using the camera, obtain image frames, based on the exposure value, obtain movement information on the camera or the lens assembly by using the at least one sensor while the image frames are being obtained, determine an image stabilization strength, based on the exposure value and the movement information, and perform video digital image stabilization (VDIS) for the image frames, based on the image stabilization strength.

Abstract: An electronic device is provided. The electronic device includes a first camera, a second camera spaced apart from the first camera, and a processor. The processor is configured to obtain a first image of external objects using the first camera, obtain a second image of the external objects using the second camera, identify a specified object in which pieces of depth information are generated from among the external objects included in the first image and the second image based on phase difference comparison between the first image and the second image, then select depth information about the specified object among the pieces of depth information based on a degree of spreading of a point corresponding to the specified object included in at least one of the first image and the second image, and generate depth information about the external objects including the specified object using the selected depth information.
