  • Patent number: 8764533
    Abstract: Spotlight information that contains at least coordinate information indicating a coordinate at which an object is positioned is generated in accordance with a selection operation for selecting the object. A spotlight screen, including a spotlight illuminating region for receiving an operation input and a darkened region for receiving a request to cancel the selection operation, is displayed in accordance with the generated spotlight information. The received selection operation is determined in a case where a selection of the spotlight illuminating region is received. A predetermined region having its center at a coordinate at which the object is positioned is determined as the spotlight illuminating region. A predetermined region including a coordinate on which an object, for which the selection operation is not received, exists is determined as the darkened region in a case where there is the object within the spotlight illuminating region.
