Abstract: A method to maximize use of the field of view for an imaging system is provided herein. An imaging device can be part of the imaging system and include a detection unit and an alignment unit. The method includes capturing an initial image of an object and then calculating a rotational angle and zoom factor for the object in order to maximize the object's footprint within the field of view. Once the calculations are complete a computer can instruct the detection and alignment units to reconfigure their orientations relative to the object.

Abstract: Systems and methods generate a projected image at an optimal exposure time. Images are captured different exposure times. Pixels that satisfy an intensity threshold percentage for each image are selected. The intensity values of the selected pixels are then evaluated to determine whether the selected pixels are distributed above a lower intensity threshold and below an upper intensity threshold. The linear relationship is projected to determine an optimal exposure time that has an optimal exposure time duration that exceeds each exposure time duration associated with each of the captured images when the linear relationship exists between each of the captured images. A projected image associated with the optimal exposure time is generated from one or more of the captured images.
