Dot pattern recognizing device and content executing device

摘要

Disclosed is a device for recognizing a dot pattern, including: a dot pattern recognizing unit configured to recognize a first dot pattern and a second dot pattern on a recording medium, on which a dot pattern is formed; a location information extracting unit configured to extract first location information from the first dot pattern, and extract second location information from the second dot pattern; a communication unit configured to transmit the first location information and the second location information to the content executing device; and a controller configured to control the dot pattern recognizing unit, the location information extracting unit, and the communication unit, in which the first dot pattern is a dot pattern recognized when the device is spaced apart from the recording medium, and the second dot pattern is a dot pattern recognized when the device is in contact with the recording medium.

主权项

1. A device for recognizing a dot pattern, comprising:
a dot pattern recognizing unit configured to recognize a first dot pattern and a second dot pattern on a recording medium, on which a dot pattern is formed, in stages; a location information extracting unit configured to extract first location information from the first dot pattern, and then extract second location information from the second dot pattern; a communication unit configured to transmit the first location information to a content executing device, and then transmit the second location information to the content executing device; a recognition mode setting unit configured to set the device so that the device is operated in a first recognition mode set to recognize only the second dot pattern according to the amount of charge left in a battery, or in a second recognition mode set to recognize the first dot pattern and the second dot pattern; and a controller configured to control the dot pattern recognizing unit, the location information extracting unit, the communication unit, and the recognition mode setting unit, wherein the first dot pattern is a dot pattern recognized when the device is spaced apart from the recording medium, and the second dot pattern is a dot pattern recognized when the device is in contact with the recording medium.
