Summary:Devices and methods employing dual target auto exposure. An imaging device is disclosed, and includes an illumination subsystem operative for projecting an illumination pattern; an aiming subsystem operative for projecting an aiming pattern; an imaging subsystem comprising an image sensor array and an imaging assembly used for focusing an image to the image sensor array; a housing comprising the illumination subsystem and the imaging subsystem. The device is configured to acquire a first plurality of images exposed in the illumination period of the illumination pattern based on a first control parameter, adjust the first control parameter for a subsequent image in the first plurality of images based on a previous image in the first plurality of images, acquire a second plurality of images exposed in the non-illumination period of the illumination pattern based on a second control parameter, adjust the first control parameter for a subsequent image in the second plurality of images based on a previous image in
