Abstract

A monitor transmits the monitored image signals which have been obtained by imaging subjects to be monitored corresponding to terminals of image signals from a plurality of image pickup apparatuses to the corresponding terminals, respectively. At the terminals, the monitored image signals which have been obtained by imaging subjects to be monitored corresponding to the terminals are respectively received to display the monitored image signals thus received, respectively.

wherein said plurality of terminals each having a unit for receiving as its input a monitored image signal which has been obtained by imaging an associated one of the subjects to be monitored corresponding to an associated one of said terminals from said monitor, and a display unit for displaying thereon the monitored image signal thus received, and

wherein said monitor further has a unit for obtaining relative positional relationship between the subjects to be monitored on the monitored image signals and associated ones of said image pickup apparatuses which imaged the subjects to be monitored based on the monitored image signals, a unit for recording therein positional information of the obtained positional relationship, and a unit for displaying thereon either the positional information of the subjects to be monitored or position movement information thereof based on the obtained positional relationship.

2. A monitored image signal delivering system according to claim 1, wherein identification markers corresponding to the subjects to be monitored are attached to the subjects to be monitored, respectively,

wherein said controller further has a unit for detecting the identification markers attached to the subjects to be monitored, respectively, and a unit for identifying associated ones of said terminals corresponding to the detected identification markers, and

wherein said controller transmits the monitored image signals to the identified terminals, respectively.

3. A monitored image signal delivering system according to claim 2, wherein said identification markers are label identification information corresponding to the subjects to be monitored.

4. A monitored image signal delivering system according to claim 2, wherein identification markers which are the identification markers corresponding to the subjects to be monitored, respectively, and which can be imaged using said image pickup apparatuses are respectively attached to the subjects to be monitored,

wherein said monitor further has a unit for detecting images of the identification markers from the image signals which have been obtained by imaging the identification markers, and a unit for identifying the associated ones of said terminals corresponding to the detected identification markers, and

wherein said monitor transmits the image signals each having the image of the identification marker in the form of the monitored image signals to the identified terminals.

5. A monitored image signal delivering system according to claim 4, wherein the identification markers are either identification codes used to specify the subjects to be monitored, respectively, or names of the subjects to be monitored.

6. A monitored image signal delivering system according to claim 4, wherein said monitor further includes a memory for storing therein the positional information of the correspondence relationship between said terminals and the identification markers of the subjects to be monitored, and a unit for transmitting the image signal having the image of the identification marker in the form of the monitored image signal to the identified terminal by referring to said memory.

7. A monitored image signal delivering system according to claim 1, wherein members with each of which the passage through a gate is checked are attached to the subjects to be monitored, respectively, and

wherein said monitor further has a gate apparatus for detecting that the member has passed through said gate, and said image pickup apparatuses for imaging the subject to be monitored having said detected member attached thereto.

8. A monitored image signal delivering system according to claim 1, wherein members with each of which the passage through a gate is checked are attached to the subjects to be monitored, respectively, and
