Abstract: An imaging device, and a method for automatic focus in said imaging device is disclosed. The imaging device comprises a first imaging system with a first lens system, a second imaging system with a second lens system, and an autofocus controller. The imaging device and the method are respectively able to perform a step by step autofocus search with the first lens system and the second lens system on the basis of a search parameter. Thereby, the autofocus controller obtains a result of an objective function for each of the first lens system and the second lens system after each autofocus search step, and updates the search parameter depending on the obtained results of the objective function for each of the first lens system and the second lens system.

Abstract: A method and a multi-camera system for obtaining pictures with improved image quality. At least two cameras are used for each capturing an image, and a fast shooting mode is employed. The fast shooting mode may work in a preprocessing mode, in which the captured image of highest sharpness is acquired as a final picture, or may work in a post processing mode, in which multiple captured images are acquired, and are then post-processed to obtain a final picture of high image quality. In both modes it may be automatically determined, whether to activate the fast shooting mode or not. The determination is based on a relative movement of the multi-camera system to an object of interest, or is based on a shooting behavior of the user.
