Abstract
Image data from a camera is used to identify one or more items in a dynamic field of view for item identification and tracking. The camera focus setting may be adjusted to different depth of field based on estimated distances to the items within the image data. After adjusting the focus setting, additional image data may be collected to capture a sharper image of the item and ensure sufficient clarity for item recognition based on item identifiers visible on the items within the image data.
