Abstract: Methods and apparatuses are provided for synchronizing data by an electronic device. A first operation characteristic of a first image sensor of the electronic device and a second operation characteristic of a second image sensor of the electronic device are identified. At least one of a first access period of a first row of the first image sensor and a second access period of a second row of the second image sensor is changed, based on a difference between the first operation characteristic and the second operation characteristic, to synchronize the first access period and the second access period. The second row corresponds to the first row. Image data corresponding to the first row is acquired through the first image sensor based on the synchronized first access period. Image data corresponding to the second row is acquired through the second image sensor based on the synchronized second access period.

Abstract: An apparatus and method for adjusting camera exposure are disclosed. The apparatus includes an electronic device The electronic device includes a camera, a display, and a processor. The processor is configured to receive a first user input for selecting a first area of a preview image from a first screen for displaying the preview image, to identify an exposure state of the selected first area responding to the first user input, to provide a second screen for displaying a portion of the preview image corresponding to the first area if the exposure state of the selected first area is an over-exposure state, to receive a second user input for selecting a second area of the preview image from the second screen, and to adjust an exposure of the preview image based on the exposure state responding to the second user input.
