Abstract: According to one embodiment, an information processing device for analysis of images from a camera positioned to view a checkout apparatus includes a control unit. The control unit is configured to perform an analysis of a first sub-area of images from the camera to detect a movement of an operator or merchandise at the checkout apparatus. The control unit outputs a notification of non-registration if the analysis of the first sub-area of the images indicates that an item of merchandise has arrived at a post-registration storage place of the checkout apparatus from a pre-registration storage place of the checkout apparatus without passing through a registration region. The control unit adjusts a boundary position between the first sub-area and a periphery area in the images from the camera based on how often the operator or the merchandise is detected as crossing the boundary position.
