Abstract
Information codes each having a predetermined size, in which specific information for specifying the type of item is recorded, are provided by using shelf boards at positions where the respective types of the items are displayed on a display shelf. When two or more information codes whose specific information is read are included in one captured image captured by an imaging unit while no detected code is stored in the storage unit, the relative positional relationship among the two or more information codes is detected based on the sizes of the information codes. Further, when the captured image is determined as a partially undetected state, in which an undetected code is included together with at least one detected code, the relative positional relationship of the undetected code relative to the detected code is detected based on the size of the reference code.
