Patent ID: 8269874

Claim:
An image display system comprising: an image input apparatus; and an image display apparatus that is connected with the image input apparatus and displays an image obtained by the image input apparatus, the image input apparatus including: an image pickup unit that images a subject, a movable holding unit that holds the image pickup unit and can be selectively brought into an imaging state where the subject can be imaged and a non-imaging state where the subject is not imaged when the entire length of the movable holding unit is shortened to the shortest length without detaching the image pickup unit from the movable holding unit, a state detection unit that detects whether the movable holding unit is in the imaging state or the non-imaging state; and a control unit that brings the image input apparatus and the image display apparatus into a disconnected state where a transmission path for transferring data between the image input apparatus and the image display apparatus is logically disconnected when the state detection unit determines that the movable holding unit is in the non-imaging state, and brings the image input apparatus and the image display apparatus into a connected state where the transmission path is logically connected when the state detection unit determines that the movable holding unit is in the imaging state.
