Abstract
An image acquisition arrangement that acquires at least one image of at least one portion of a scene has a camera and an illumination source controlled by a control module. The camera includes an image recording medium and a shutter controllable to enable the image recording medium to acquire the image. The illumination source is configured to illuminate the scene for a selected time period. The control module controls the camera and illumination source to facilitate acquisition of the image by the camera, the control module enabling the shutter to, in turn, enable the image recording medium to acquire the image and contemporaneously to enable the illumination source to illuminate the scene, the time period during which the shutter enables the image recording medium to record an image being a function of the time period during which the at least one illumination source illuminates the scene.
