This publication describes techniques for image-capture devices (e.g., smartphones, laptops, tablets) to automatically zoom in on object(s) of interest in a photographic scene. In aspects, through utilization of a machine-learned technique (e.g., a Visual Saliency Model), an Automatic Zoom Manager can detect a visual saliency region within an image, generate a bounding box enclosing the visual saliency region, and calculate an appropriate zoom ratio. The Automatic Zoom Manager can then implement the calculated zoom ratio to automatically achieve a suitable zoom for the photographic scene.
