Abstract: Embodiments disclose an image generating method and a dual-lens device. The method includes determining a first processing parameter and a second processing parameter. The first processing parameter is different from the second processing parameter. The method also includes acquiring, according to the first processing parameter, a first image captured at a first moment by a first image sensor corresponding to a first lens, and acquiring, according to the second processing parameter, a second image captured at the first moment by a second image sensor corresponding to a second lens. When a photographing operation instruction is received, the acquired first image and the acquired second image are synthesized to generate an image.
