Receiver, shutter glasses, and communication system

Shutter glasses having a right eye shutter and a left eye shutter, the shutter glasses comprising:

• a communication device which receives data incoming intermittently;
• a first control circuit which analyzes the data received by the communication device to identify whether or not a predetermined reference timing signal pattern is present in the data;
• and
• a timer part which counts a clock from an initial value, generates control signals for opening and closing the respective right and left eye shutters according to a resulting count value, and if the count value reaches a predetermined interval value, resumes counting the clock at the initial value, the timer part changing the initial value to reduce a count of the clock between the initial value and the interval value if the first control circuit identifies the predetermined reference timing signal pattern to be present.

A communication system comprising:

• a transmitter which intermittently transmits data containing a predetermined reference timing signal pattern;
• and
• a receiver that includes a communication device which receives the data,
• the receiver including
• a first control circuit which analyzes the data received by the communication device to identify whether or not the predetermined reference timing signal pattern is present in the data, and
• a timer part which counts a clock from an initial value, generates a control signal for a device to be controlled according to a resulting count value, and if the count value reaches a predetermined interval value, resumes counting the clock at the initial value, the timer part changing the initial value to reduce a count of the clock between the initial value and the interval value if the first control circuit identifies the predetermined reference timing signal pattern to be present.
