x=0; Under the situation that only detects the change in zoom, d
x=d
y=0; Under the situation that only detects the rotation behavior, a=1.
Lock-on signal generation device 13 is from the change information that detected by change detecting device 12 and produce the lock-on signal of the vision signal that is hunted down of the part object that is used to obtain the panorama object at preceding lock-on signal.For example, as shown in Figure 5, in lock-on signal generation device 13, at lock-on signal x, y and a of preceding generation and current use

p, new lock-on signal x, y and a
pBe provided to the lock-on signal of wherein storing with renewal from its 13a at front signal, they are output to dispensing device 14 simultaneously.When image capture apparatus 1 carries out image do not catch when handling, in front signal memory 13a, storing predetermined lock-on signal as initial value.Such as the center x of the transducer in Fig. 2, y and at the half value a of maximum zoom amount
pWhen image capture apparatus 1 begins to catch processing, at initial value signal x, y and a in front signal memory 13a
pBe used as lock-on signal and send to remote image sensing apparatus 2.
When the value of information converting hour, for example work as d
x=1 o'clock, the image of the part object of the panorama object that shows on the portable terminal device 3 that has been equipped with video camera remained basically unchanged; In order to handle this point, preferably provide round off part 13e, 13f and 13g, by them, if d
x, d
yWith the predetermined value of a less than them, then d
xAnd d
yBe rounded to 0, a is rounded to 1, and they are provided to addition part 13b and 13c and the part 13d that multiplies each other.Described abandon the above-mentioned predetermined value that is provided with among part 13e, 13f and the 13g in the neutralization of described discarded part branch according to the use pattern of this remote display system and different.Under the situation of the part object that shows remote scene, described predetermined value is selected as bigger, and prevents that at using system they are selected as less under the situation of error behavior of space; For for example d
x, when its minimum be 5 or more hour it to be considered round down be 0.
Generally, it is not preferred upgrading the lock-on signal that will send to remote image sensing apparatus 2 when frame of each reception, because its increases treating capacity.Even carry out renewal for each frame, the user also is difficult to perceive the change in the part subject image that is received.Therefore, can come at interval to send lock-on signal by reasonable time to remote image sensing apparatus 2.Can come suitably to determine this time interval according to the use pattern of system: for example, when changing quickly the situation of object is under the situation at traffic monitoring, be per 1/10 second; When object was scenery, for example per 1/3 second was every several seconds in some cases.For this reason, update instruction part 12d for example is provided in change detecting device 12, and receive buffer storage 12a and come to catch the vision signal on every side of a frame predetermined update time at interval in response to the instruction from update instruction part 12d, change-detection part 12c is to come change detected information update time at interval.Perhaps, receive the content of buffer storage 12a for each frame update of vision signal on every side, and when detecting change information, the content that receives buffer storage 12a is sent at preceding frame memory 12b at every turn.When all changes information that detects in change-detection part 12c is zero, promptly as d in this example
x=d
y=0 and during a=1, needn't produce and send lock-on signal to the remote image sensing apparatus, in the remote image sensing apparatus, also needn't produce lock-on signal.Can only optionally produce and send lock-on signal corresponding to having experienced those change informations that change.
In remote image sensing apparatus 2, the lock-on signal that is received by signal receiving device 23 is imported into image acquiring apparatus shown in Figure 4 24, and the previous lock-on signal that receives is stored among the storage area 24a with the new lock-on signal that receives.According to the lock-on signal in storage area 24a of renewal like this, image acquiring apparatus 24 is extracted in the vision signal of the part object in the panorama object of being taken by omnirange video camera 21.For example, the output of the imageing sensor 7 of omnirange video camera 21 is as shown in Figure 2 from always according to treating that lock-on signal (benchmark pixel position signalling) is extracted in its center (benchmark) and has pixel (x, the state of the vision signal in a frame zone 71 y) is always changed into according to the lock-on signal that upgrades and is extracted in the state of vision signal that its center has a frame zone 72 of pixel (x ', y ').In the example of Fig. 2, the shooting direction out of plumb ground that has been equipped with the portable terminal device 3 of video camera changes, and zoom amount and shooting direction also not only turn right, i.e. change information d
