In addition, Fig. 5 represents, the detailed components of aforesaid automatic focusing and remote control receiving unit.Wherein, automatic focusing and remote control receiving unit 202 are by the prime amplifier 221 that is connecting light receiving element PSD; The multiplexer 222 that is connecting prime amplifier 221 and CPU (central processing unit) 201; The bandpass filter 223 that is connected with multiplexer 222; The amplifier 224 that is connected with bandpass filter 223; The integrator 225 that is connected with multiplexer 222 with amplifier 224; Comparer 226 formations such as grade that are connected with CPU (central processing unit) 201 with integrator 225.
Below, the remotely controlled cameras of aforementioned formation is further stated.
At first, add power supply, make CPU (central processing unit) 201 begin out work, remote-controlled launcher 1 does not separate from camera body, then the remote control mode switch S
W1Be failure to actuate, promptly do the photography of subject usually with the typical CCD camera state.Therefore, only need being contained in the shutter release switch S on the remote-receiver 20
W2State judge.
If shutter release switch S

But, if the remote control shutter release S of emitter 1
1Be failure to actuate, in the time of can not detecting remote signal, then CPU (central processing unit) 201 continues the holding state of maintenance to the remote signal of remote-controlled launcher 1.
If owing to the action of aforesaid motor makes the camera lens action, and the subject focus is done to regulate automatically, then CPU (central processing unit) 201 is carried out the subsequent action of subject.
Shown in Fig. 6 (c), between the remote signal that senses remote-controlled launcher 1, again through the action of just photographing behind the certain hour, its reason be this will make that the user is desirable must oneself desirable attitude, and be unlikely to take the photograph into factitious photo.
Aforesaid automatic focusing and remote control receiving unit 202 not only can be more accurate because light receiving element SPD has utilized CCD electric charge integrated device the signal of detection remote-controlled launcher 1 and the reflected signal of subject, but also can be used as the light receiving element that transmits that is used to detect remote-controlled launcher 1, utilize with adding optical conductor that light intensity changes internal feature and detect the signal of the emission of remote-controlled launcher 1.
The camera that the present invention who works in a manner described is remote-controlled, in order to detect remote signal, another remote control receiving unit can be set, and utilize the ultrared light receiving element that can detect that is provided with for automatic focusing to detect the remote-control transmitting signal, thereby can realize the remote control of camera action.Therefore, the formation of camera is oversimplified, miniaturization, this is very beneficial for reducing the camera cost of manufacture, can realize the advanced of middle-grade phase mechanical goods.
In addition because the remote-control transmitting signal is applied directly on the light-receiving member of the red ejected wave that just detects subject reflection, therefore make to the sensing range when this detects subject reflected signal more distant location carry out remote control and also become possibility.
