Patent ID: 6977677

Claim:
An imaging apparatus comprising: imaging means ( 1 , 5 ); optical means (la) for receiving and forming an image on said imaging means which generates an image signal from said image; a/d converting means ( 3 ) for a/d-converting said image signal; signal processing means ( 4 ) for processing said image signal from said a/d converting means to generate a digital video signal; communication means ( 6 ) for transmitting said digital video signal to a transmission line and receiving a clock signal and timing data transmitted through said transmission line, said timing data indicating a communication timing; clock signal detection means ( 6 d ) for detecting said clock signal received by said communication means; timing signal generation means ( 7 - 10 ) for generating timing signals from said detected clock signal to control said imaging means, said a/d converting means, said signal processing means, and said communication means; and communication control means ( 11 ) for detecting a communication timing from said timing data, judging whether said communication timing is detected within a predetermined condition, and controlling said timing signal generation means to stop transmitting said digital video signal when said communication timing is not detected within said predetermined condition.
