SV camera 30 is combined with theTV telephone adapter 33, the combiningdetection contacts voltage detection circuits 47 and 48 to fail. The combiningvoltage detection circuits 47 and 48 convert the combining voltage into digital signals so as to transmit them to the corresponding CPUs as detection signals. When theCPU 7 of theSV camera 30 detects the thus-supplied signal, theSV camera 30 temporarily stops its camera operation but commences an operation to serve as an image input and recording device for the TV telephone. As shown inFIG. 1 , theTV telephone adapter 33 is provided with the chargingcircuit 46 for theSV camera 30 so that charging of thebattery 45 of theSV camera 30 is commenced simultaneously docking. The SV camera and the TV telephone adapter thus combined with each other operate while performing communication by means of their CPUs via the command I/Os -
FIG. 8 illustrates the configuration of the manipulation switches according to this embodiment. Referring toFIG. 8 ,reference numeral 30 represents the SV camera, 33 represents the TV telephone adapter and 34 represents a shutter switch for thecamera 30, theshutter switch 34 acting as a memory freeze switch when combining has been completed.Reference numerals camera 30, the twoswitches Reference numeral 38 represents a Rec trigger switch for recording data to thefloppy disk 5, which is a recording medium and which is loaded into thecamera 30.Reference numeral 39 represents a TV telephone transmission switch and 40 represents a switch for selecting an input signal for any of three inputs, that is, the input for the camera system, that for the floppy system (according to this embodiment, it is expressed as “SV” because the SV floppy disk is employed) and that for an external system. When any of the above-described switches is depressed, the corresponding CPU discriminates this fact so as to perform a control operation by means of communication.FIG. 10 illustrates the status of wiring arranged in the command I/Os -
FIG. 11 is a flow chart which illustrates the contents of the command interface when the switch for theSV camera 30 is depressed. In a state where no switch is depressed, an “I/F Enable/{overscore (Disable)}” signal is enabled. When any of the switches for thecamera 30 is depressed, the CPU7 for thecamera 30 sets any of theinternal switches switches TV telephone adapter 33 confirms that the above-described two signals have been activated, it disables the “I/F Enable/{overscore (Disable)}” signal at the command I/O9 to make a response. When the CPU7 of theSV camera 30 detects a response signal thus-transmitted, the CPU10 discriminates that the command wait state has been realized and it transmits a Clock signal and a command data signal which is in synchronization with the Clock signal so as to supply command information to the CPU10. If, for example, thefreeze switch 34 shown inFIG. 8 is depressed, the SV camera side CPU7 switches over theinternal switches 27 to 29 in accordance with setting of theinput signal switch 40 before it issues a freeze command to the adapter side CPU10 (in a case where the address UP and DOWN switches 35 and 36 are depressed, the command issue can be eliminated). The CPU10, which has received the above-described signal, reads the command in response to a synchronization signal before it interprets the command to execute it. In a case where no error takes place after the execution, the “I/F Enable/{overscore (Disable)}” signal is again enabled before camera side CPU7 is acquainted with the completion of the execution. If an error has taken place, an “Error” signal is, as shown inFIG. 13 , activated to transmit/return error information as “Data” which is in synchronization with “Clock” before the “I/F Enable/{overscore (Disable)}” signal is again enabled to complete the communication. When the camera side CPU7 for theSV camera 30 detects the “Error” signal, it reads error data before it confirms a fact that the “I/F Enable/{overscore (Disable)}” signal has been enabled. Then, it again enables the “I/F Enable/{overscore (Disable)}” signal at the command I/O8 to complete the communication. If no error has taken place, the fact that the “I/F Enable/{overscore (Disable)}” signal at the command I/O9 has been enabled is confirmed as shown inFIGS. 11 and 12 before it enables the “I/F Enable/{overscore (Disable)}” signal at the command I/O8 to complete the communication. The communication protocol is arranged to act as described above when the manipulation switch for theSV camera 30 is depressed. - Also, in a case where the switch for the
TV telephone adapter 33 is depressed, command data is communicated so that the adapter side CPU10 causes the camera side CPU7 to operate correspondingly. Since the difference from the above-described case lies in only a fact that the switch is set after the command has been issued from theTV telephone adapter 33 because theinternal switches camera 30. All of the other operations are performed in accordance with the same protocol.FIGS. 14 and 15 respectively illustrate a flow chart and a time chart concerning the above-described operation. Since the construction is arranged in such a manner that the SV camera and the TV telephone adapter shown inFIGS. 11 and 12 are replaced with each other, their descriptions are omitted here. - The flow of an image signal and setting of the internal switches in each of the operational modes will now be described.
-
FIG. 3 illustrates the flow of the signal when the freeze signal is depressed. In the freeze operational mode, the CPU10 discriminates the input signal to be frozen in accordance with theinput signal switch 40. In a case where the camera has been set, an image signal transmitted from the CCD1 passes through the imagepickup processing circuit 2 so as to be converted into a color difference signal before it is received by theswitch 29 via theswitch 27. In a case where the SV is set by theinput signal switch 40, areproduction signal 6 supplied from thefloppy disk 5 is reproduced by thehead 4. The reproduction signal thus-read passes through theswitch 28 before it is, by thereproduction processing circuit 6, converted into a color difference signal which can be frozen in theimage memory 17. The converted signal is then supplied to theswitch 29. As described above, the image signal from the camera or the SV passes through theswitch 29 before it is received by the A/D converter 15 so as to be converted into a digital signal. The digital signal thus-obtained is supplied to thememory controller 16. Thememory controller 16 fetches the thus-supplied digital signal into theimage memory 17 in accordance with the command issued from the CPU10 so that the freeze operation is completed. In a case where an external 16 input signal is frozen, an image signal supplied through the VIDEO IN is converted into a color difference signal by thedecoder 20 before it is converted into a digital signal by the A/D converter 21. The digital signal thus-obtained is then supplied to the memory controller. The memory controller fetches the above-described digital signal into theimage memory 17 in accordance with a command issued from the CPU10 so that the image signal is frozen. - An operation of displaying the throughput image and that of displaying the memory image will now be described.
FIG. 4 is a flow chart which illustrates the flow of the signal for use in the above-described operation. When the “through/memory” display switch is depressed, the CPU10 first discriminates that the state is the through display mode or the memory display mode. In a case of the through display mode, theinput signal switch 40 is used to discriminate the input signal to be through-displayed. The result of this discrimination is any of the through display of the camera image, the through display of the SV reproduction image or the through display of the external input image. The image signal flows as follows, but the flow from each device to thememory controller 16 is omitted here because it is the same as that which takes place in the above-described freezing operation: the image signal supplied to thememory controller 16 passes through the memory controller in which it is not subjected to any operation before it is transmitted to the D/A converter 18. The image signal is again converted into the analog signal in the D/A converter 18 before it is converted into a video signal by theencoder 19. The video signal thus-obtained is transmitted through a VIDEO OUT terminal. In a case of the memory display, the data in theimage memory 17 is read by thememory controller 16 in synchronization with the video signal before it is converted into an analog signal by the D/A converter 18. The analog signal thus-obtained is transmitted through the VIDEO OUT terminal. Thus, the through image and the memory image are through-displayed. - Then, the flow of the signal at the time of an operation of recording (Rec) data to the
floppy disk 5 will now be described with reference toFIG. 5 . When theRec switch 38 is depressed, the CPU10, similar to the above-described freezing operation, discriminates the device which has transmitted the signal to be recorded, the discrimination being made in accordance with the action of theinput signal switch 40. In a case where data supplied from the camera is recorded, the signal supplied from the CCD1 is converted into the color difference signal by the imagepickup processing circuit 2 before it is supplied to theswitch 27. In a case where data supplied from theimage memory 17 is recorded, the content of theimage memory 17 is read by thememory controller 16 before it is D/A-converted by the D/A converter 14 so as to transmit it to theswitch 27. In a case where data of an external input signal is recorded (EXT), a signal supplied through the VIDEO IN terminal is made to be a difference signal by thedecoder 20 before it is transmitted to the A/D converter 21. Then, it passes, in the form of the digital signal, through thememory controller 16 before it is again converted into the analog signal by the D/A converter 14. The analog signal is then transmitted to theswitch 27. The signal thus-supplied to theswitch 27 is converted into a signal to be recorded on thefloppy disk 5 by therecord processing circuit 3 before it passes through theswitch 28. As a result, data is recorded on thefloppy disk 5 by thehead 4. - The flow of the data transmission will now be described with reference to
FIG. 6 . When thetransmission switch 39 disposed in the manipulatingportion 13 is depressed, the CPU10 discriminates it so that a transmission sequence is commenced. In the transmission sequence, pixel data at an arbitrary address, which corresponds to the transmission mode, is sequentially read from theimage memory 17 by using thememory controller 16. Data thus-read out is transmitted to the D/A converter 22 by the CPU10 before it is converted into an analog signal. Then, it is, by themodulation circuit 23, modulated in synchronization with the carrier and in accordance with the transmission format for the TV telephone before it is transmitted to the NCU24. The NCU24 performs terminative and unbalanced/balanced conversions to transmit the above-described signal to the telephone circuit. The transmission sequence is constructed as described above. - The receiving sequence will now be described with reference to a flow chart shown in
FIG. 7 . The data receiving operation is completely automated while eliminating the provisions of switches. Data supplied to the NCU24 through the telephone circuit is subjected to the terminative and unbalanced/balanced conversions in the NCU24 before it is supplied to thedemodulation circuit 25. The signal is then converted into the video rate signal in thedemodulation circuit 25 before it is digital-converted by the A/D converter 26 so as to be read by the CPU10. The signal read by the CPU1 is transmitted to thememory controller 16 so that it is written to an address in anarbitrary image memory 17 which corresponds to the transmission mode. The data receiving sequence is constructed as described above. - The basic operation according to this embodiment is arranged as described above. However, the present invention is not limited to this. For example, a modification may be employed in which the signal supplied from the
floppy disk 5 is fetched by a means which freezes it to theimage memory 17 before thefloppy disk 5 is interchanged so as to record it by a means capable of recording the signal in theimage memory 17 to anotherfloppy disk 5. In this case, data dubbing and editing can be performed. Another structure may be employed in which thephotodetector 12 is provided for enabling all of the switches to be operated in a remote-control manner, such that data is read through the I/O11 by the CPU10 to perform the above-described operations. - Other Embodiments
- Another method of the interface to be established between the
SV camera 30 and theTV telephone adapter 33 will now be described with reference toFIG. 9 , this method being able to be employed as an alternative to the method of the command interface according to the first embodiment shown in FIGS. 1 to 8. This embodiment is arranged to be different from the above-described method in which hand shaking is performed by means of the command I/O but it is arranged in such a manner that the CPU10 for theTV telephone adapter 33 controls the overall operation. When theSV camera 30 and theTV telephone adapter 33 are combined with each other, the TV camera side CPU7 is perfectly separated from the other I/O devices by abus controller 50 so that it is brought into an independent state. However, a microcomputer bus (an address bus, a data bus and the like) for theTV telephone adapter 33 is connected by aconnector 49 so that each I/O device of thecamera 30 is brought into a state under control of the CPU10. As a result, the CPU10 is enabled to perform all of the controls such as scanning of the manipulation switches of the two elements, input the image and the operation of the floppy disk. As a result, problems which can take place due to the hand shake operation, such as the time lag, can be overcome. The most significant advantage obtainable from this method lies in that no structure must be provided for software for thecamera 30 to act when theTV telephone adapter 33 is connected, and thereby a load required to develop it can be reduced. - As described above, according to this embodiment, the TV telephone adapter is combined with the SV camera to constitute a still image TV telephone apparatus, and the camera is enabled to act as the image input apparatus and image recording apparatus. As a result, the subject to be photographed can be varied considerably and filing and search of the image can be completed easily. Therefore, a photograph taken at the time of a tour by the user can easily be transmitted to friends, or a photograph of a baby of the user can also easily be transmitted to the user's parents living far away. Furthermore, if the
TV telephone adapter 33 is previously connected to a monitor TV, the necessity of connecting theSV camera 30 to the monitor TV for the purpose of reproducing the image can be eliminated. Therefore, a user who cannot easily establish the wire connection can easily produce the image. Also, charging can be performed simply by placing theSV camera 30 on theTV telephone adapter 33. Therefore, charging can be easily performed while eliminating a necessity of performing a particular charging operation. - Although the recording medium for use in the recording portion comprises the SV floppy disk according to the above-described embodiments, the present invention is not limited to this. Another recording medium, for example, an optical disk or a tape-like medium may be employed. As an alternative to this, a solid memory, for example, a semiconductor memory or a Bloch line memory may be employed.
- Although the analog circuit is employed as the telephone circuit according to the above-described embodiments, it may be replaced by a digital circuit such as an ISDN. In this case, the NCU is used for the ISDN circuit.
- Although the adapter for transmitting a still image is employed as the TV telephone adapter for use to serve as the public circuit adapter according to the above-described embodiments, an adapter for transmitting movable images may be used in place of the above-described adapter. The necessity lies in that it can be mounted on a detachable camera and it is able to transmit an image signal supplied from the camera or transmit the same reproduced from a record reproducing portion of the camera.
- Although the attachment/detachment detection means is structured as shown in
FIG. 2 , the present invention is not limited to this. Another method, for example, a method for simply detecting the state of the switch, may be employed. - As described above, according to the above-described embodiments, the camera having the image pickup portion and the recording portion is made to be detachable from the image transmission adapter. Therefore, the subject can freely be photographed and the image obtained by photographing can be transmitted through a public circuit.
- Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form may be changed in the details of construction and the combination and arrangement of parts may be modified without departing from the spirit and the scope of the invention as hereinafter claimed.
