A method for image acquisition may be provided. The method may include sending an exposure instruction to a plurality of image sensors. The method may further include controlling exposure time periods of at least one exposure group to obtain a plurality of frame images based on the exposure instruction. For each of the at least one exposure group, the exposure group may include a plurality of exposure regions corresponding to the plurality of image sensors, imaging positions corresponding to the plurality of exposure regions may be the same, and the exposure instruction may cause that a relationship between midpoints of exposure time periods of the plurality of exposure regions in the exposure group satisfies a condition.

Systems and methods for controlling exposure time periods for image acquisition

The present disclosure relates to systems and methods for exposure control. The systems and methods may obtain a target frame brightness value of the image. The systems and methods may also obtain an exposure mode of the electronic device. The systems and methods may also obtain an exposure table corresponding to the exposure mode. The systems and methods may also determine a target value, corresponding to the target frame brightness value, for each of the one or more exposure parameters based on the exposure table. The systems and methods may also adjust one or more of the at least one lens, the at least one exposure-time controller, and the at least one sensor according to the target values of the one or more exposure parameters.
