Abstract: Scanning apparatuses and related methods capable of locating object to be scanned are disclosed. One of the proposed scanning apparatuses includes: a tray for supporting objects to be scanned, wherein the tray is provided with a machine detectable mechanism; a detecting module for detecting a pattern of the machine detectable mechanism; a control circuit coupled to the detecting module for identifying at least target area on the tray according to the detecting result of the detecting module and for setting scan parameters according to a location of the at least one target area; and a scanning module coupled to the control circuit for scanning the at least one target area according to the scan parameters.
