Claim Text:
1. A camera for capturing an image of an object, comprising: a first light source; a second light source; an image-sensing system comprising at least a first image sensor; a multiple branch optical system that transmits outgoing light from the first and second light sources to the object, and transmits incoming light from the object to the image-sensing system, the multiple branch optical system comprising an autofocusing element that varies the focus of the incoming light; an image display; a controller that controls the operation of the first and second light sources, controls acquisition of images by the image-sensing system, and controls the display of images on the image display, the controller activating the first light source and using the resulting captured image to automatically adjust the image exposure parameters and automatically adjust the variable power optical element to improve the image focus, and the controller then activating the second light source and acquiring one or more images of the object while the second light source is activated; and a closed loop control system having image shift as an input, where the control system determines the magnitude and direction of frame shift from a nominal center and generates a control signal that is used to modify the optical system to move the image back toward the nominal center.
