Description

FIXED VIDEO DEVICE

  The present invention relates to a fixed video device, such as a fixed video camera (electronic photographic device) in which the image signals of the captured or reproduced images can be directly input to an image processing device such as a

personal computer.

  Various fixed video cameras are known in which images (images or graphics) are recorded in the form of electrical signals as well as various fixed video playback devices in which the images taken (recorded) by a fixed video camera are displayed or printed. The expression "Fixed video device" which will be used later includes the fixed video camera as well as the fixed video reproduction device. In a current computer, in particular in a personal computer, not only the information consisting of numerical values and of letters, but also image information can be processed. Image information, for example, image data read by an image reader is input to a personal computer via a transmission interface placed inside the personal computer. The transmission interface used is usually standardized (by

example RS-232C or SCSI, etc.).

  The standard (criterion) for the emission of images in a fixed video device is not, however, identical to the standard for the transmission interface mentioned above. To enter the recorded image of the fixed video device into a personal computer in the form of image data, it is thus necessary to place a transmission interface

  image data inside the personal computer.

  Since the image data transmission interface placed in the personal computer however includes a signal processing circuit in addition to the similar signal processing circuits placed in the fixed video apparatus, the circuit arrangement becomes generally complex, from so that the number of steps to accomplish signal processing is increased, leading to deteriorated image signals. The main object of the present invention is to create a fixed video apparatus comprising an image input / output device in which the recorded image signals can be directly input to an image processing device such as a computer. personal, it does not have an interface

image signal transmission.

  To achieve the above-mentioned object, in accordance with the present invention, there is created a fixed video apparatus comprising an image signal emission means for outputting an electrical image signal, comprising a signal conversion means for convert the image signal to an image data signal which can be processed by an external image processing device and an interface which outputs the image data signal to the

  external image processing device.

  With this arrangement, the electrical image signal recorded in the fixed video apparatus can be input to an image processing device such as a personal computer not having a specific interface for the

  picture signal as picture data.

  In the case of a fixed video apparatus comprising a recording function and a reproduction function, the apparatus comprises an interface which receives and transmits a signal of image data from and to an external image processing device and signal converting means for converting the image signal which is read by the reproducing means into an image data signal or for converting the image data signal input from the interface into a signal image that can be

  recorded on the recording medium.

  With this arrangement, the image data processed by the personal computer can be saved in

the video camera

  The invention is also applied to a fixed video camera. Another object of the present invention is thus to create a compact fixed video camera in which the still image can be input to the Ilmage processing circuit.

  not having an image interface.

  To achieve the above-mentioned object, in accordance with another object of the present invention, there is created a stationary video camera comprising a camera body which has an image forming means for converting an image of an object to be taken into a electrical image signal, recording means for recording the image signal on a recording medium and reproducing means for reading the image signal recorded on the recording medium and an adapter which is detachably mounted on the camera body and which includes signal converting means for converting the image signal extracted from the recording medium by the reproducing means into an image data signal which can be processed by an external image processing device and an interface which outputs the image data signal to the

image processing device.

  With this construction, when the adapter is removed from the camera body, an image can be taken by a compact fixed video camera without the adapter, similar to a conventional fixed video camera. When the adapter is mounted on the camera body, the image captured by the camera can be input to the image processing device, such as a personal computer without an image interface, in the form of a

image data.

  Preferably, the camera body includes an external output terminal from which the image signal is supplied and the adapter includes an image input terminal which can be connected to the output terminal of the

camera body.

  The invention will be described below in detail with reference to the accompanying drawings, in which FIG. 1 is a block diagram of a first embodiment of a fixed video device in accordance

  is connected, in accordance with the present invention.

  Fig. 1 shows an example of a control circuit of a fixed video apparatus 10 comprising an image signal input device in accordance with the present

invention.

  A video signal consisting of a luminance signal and a color signal, etc., is input from, for example, a fixed video camera (CCD imaging device> etc. to an input terminal 11 of the fixed video apparatus 10. The video signal input from the image input terminal is processed to be divided into a luminance signal and a color signal in a signal processing circuit. image 13, is frequency modulated by a frequency modulation circuit 15, is amplified by a recording amplifier 17 and is then applied to a magnetic head 21 via a selection switch 19. The processed signal is recorded on a predetermined track of a magnetic recording disc 23 as a recording medium by the magnetic head 21. The image signal processing circuit 13, the frequency modulation circuit 15, the amplifier d 'record 17 and head my genetics 21 constitute a device for recording

image signal.

  The magnetic disc 23 is rotated at a constant speed by a servo motor 25 which is driven by a servo circuit 27. The servo circuit 27 controls the speed of rotation of the servo motor 25 and the alignment of the magnetic head 21 in accordance with the pulse signals emitted from a

coil PG 29.

  The operations of the image signal processing circuit 13, the switching action of the selection switch 19 and the control of the motor as well as the alignment control of the servo circuit 27 are carried out by a system control unit 31. The system control unit 31 usually consists of a microcomputer which generally controls the operation of the components or devices of the fixed video apparatus, in accordance with the program stored in the internal ROM.

  incorporated in the microcomputer.

  The image signal recorded on the magnetic disk 23 is read by the magnetic head 21 and is then delivered to the reproduction amplifier 33 via the selection switch 19. The image signal consisting of a signal luminance and of a color signal, amplified by the reproduction amplifier 33 is demodulated by a frequency demodulation circuit 35 and is then processed to become a video signal by an image signal processing circuit 37. The video signal is output to an image output terminal 39. When an image input terminal of a TV screen 61 is connected to the image output terminal 39, the image can thus be viewed on the TV screen 61 (fig. 4). The magnetic head 21, the reproduction amplifier 33, the frequency demodulation circuit 35 and the processing circuit

  image signal 37 constitutes a reproduction device.

  A functional part 41 has various switches (not shown) which are connected to the control unit of the system to actuate the start and the end of the recording and of the reproduction of the fixed video apparatus. A display portion 43 indicates various functions of the fixed video apparatus such as "recording in progress", "playback in progress", or the recording track or the playback track, etc. the indication is controlled by the system control unit 31. The construction mentioned above is

  similar to that of conventional fixed video equipment.

  The following examination will focus on the interface which is one of the most important characteristics of the

present invention.

  An A / D converter 45 which converts the analog luminance signal and the analog color signal supplied by the frequency demodulation circuit 35 into a digital luminance signal and into a digital color signal and delivers the digital signals to the RAM 47 as a buffer memory. the intermediate of a data bus is connected to the output of the frequency demodulation circuit 35. The luminance and color signals for an image plane are successively written in the RAM 47 for each pixel unit. After writing the image signals for an image plane to RAM 47, the written luminance and color signals are processed to become digital image signals which can be output to the personal computer by a digital signal processing circuit 53. The processed digital image signals are successively read and then delivered to an interface driving circuit 49 by

  the data bus intermediary.

  The interface 49 driver circuit converts

2647 6 1 4

  digital image signals from RAM 47 as standard communication signals predetermined to be output to an interface connector 51. That is, image data signals are output from the connector interface 51. As a result, if the interface connector 51 is connected to an interface connector of the personal computer 53 the image signals recorded on the magnetic disk 23 are input to the computer

  staff 63 in the form of image information.

  An interface line driver 49 can input and output the image data so that when the image data signals are supplied to it through the interface connector 51, the data signals d are output to RAM 47. The image data signals are successively written to RAM 47

  for each pixel, similar to reproduction.

  The image data for each image plane written in RAM 47 is processed to become digital image signals which can be recorded on a magnetic disk 23 by the digital signal processing circuit. The digital image signals are successively extracted from the RAM 47 and are converted into analog image signals constituted by the luminance signals and the color signals by the D / A converter circuit 55 to be

  delivered to the frequency modulation circuit 15.

  In a manner similar to the image signals supplied from the image signal processing circuit 13, the analog image signals are frequency modulated by a frequency modulation circuit 15, are amplified by the amplifier d 17 and are saved

  on the magnetic disc 23 by the magnetic head 21.

  The operations performed by the A / D converter 45, the RAM 47, the interface line driver 49 and the D / A converter 55 are controlled by the digital signal processing circuit 53. The processing circuit signal signal 53 is usually made up of a microcomputer which operates the A / D converter 45, writes and extracts data to and from RAM 47, processes digital image signals written to RAM 47 and operates the circuit interface line driver 49 as well as the D / A converter 55, in association with the control unit of the system 31. The reproduction and recording operations via the interface connector 51 are carried out by the functional part 41. Although the control unit of the system 31

  and the digital signal processing circuit 53 are.

  arranged separately in the illustrated embodiment,

  these can be constituted by the same microcomputer.

  Although the foregoing discussion has been directed to a fixed video apparatus, having a recording function, the present invention can be applied to a fixed video apparatus for reproduction only, having no recording function, as can be see it from the second embodiment of this

  invention, described below and shown in FIG. 2.

  The circuit arrangement of the second embodiment shown in FIG. 2 does not include the image input terminal 11, the image signal processing circuit 13, the frequency modulation circuit 15, the selection switch 19 nor the D / A converter circuit 55. Furthermore, the construction of the second embodiment is similar to that of the first embodiment shown in FIG. 1. In fig. 2, the components corresponding to those of the first embodiment shown in FIG. 1 are designated by

same reference numbers.

  The composite image signals which are read by the magnetic disk 23 through the magnetic head 21 are amplified by the reproduction amplifier 33 and are demodulated in frequency by the frequency demodulation circuit 35 to be supplied to the processing circuit.

  image signal 13 and to the A / D converter 45.

  The image signals consisting of the luminance signal and the color signal are processed to become video signals in the image signal processing circuit.

  37 and are then delivered to the image output terminal 39.

  The image signals sent from the frequency demodulation circuit 35 to the A / D converter 45 are converted into digital signals and are written to the

  RAM 47 through the data bus for each pixel.

  The digital image signals written in RAM 47 are processed to become digital image signals which can be output to the personal computer by the digital signal processing circuit 53. The digital image signals are successively read and delivered to the interface line driver 49 through the data bus. In the interface line driver 49, the digital image signals are converted into predetermined standard communication signals to be supplied to the interface connector 51 in the form of image data signals. If an interface connector of the personal computer 63 is connected to the interface connector 51, digital image signals are input to the computer

  staff 63 in the form of image data signals.

  Fig. 3 shows a control circuit in accordance with a third embodiment of the present invention. The third embodiment shown in FIG. 3 includes an interface for communication with a personal computer but does not include a normal image output terminal. In fig. 3, the components corresponding to those in the first or second embodiment are designated by the same reference numbers. The image signals recorded on a predetermined track of the magnetic disc 23 are read by the magnetic head 21 and supplied to the reproduction amplifier 33 in which the image signals are amplified. The amplified image signals are then frequency demodulated by the image signal processing circuit (frequency demodulation circuit) 37 and are supplied to the A / D converter 45 and to the synchronous separation circuit 57. The signals image input to the A / D converter 45 are converted to digital image signals and are written successively to RAM 47. The synchronous signals are divided from the image signals in the synchronous separation circuit 57 so that the signals synchronous

  are delivered to the system control unit 59.

  The system control unit 59 successively writes the digital luminance signal and the digital color signal which are transmitted from the A / D converter 45 to the RAM 47 for each pixel, in accordance with the synchronous signals. The system control unit 59 comprises a microcomputer which generally controls the

  flxe video device operations.

  The digital image signals for an image plane written in the RAM 47 are processed to obtain digital image signals which can be supplied to the personal computer by the system control unit 59 and are successively supplied to the line interface driver 49 through the data bus. The digital image signals are converted to standard communication image signals predetermined by the interface line driver 49 to be supplied to the connector.

interface 51.

  The fixed video device of the third embodiment shown in FIG. 3 comprising the interface capable of inputting the image signals recorded as image data to an external image processing device, the image signals can be input to a personal computer which does not have an interface

  specific for image signals.

  In the third embodiment, because the image signals are converted into image data which can be input to the personal computer without going through the image signal processing circuit 37, the circuit layout is slmplified, in comparison with the interface for image data placed in the personal computer and the number of signal processing steps can thus be reduced, leading to a lower

  deterioration of image signals.

  In the first embodiment, the image data can be saved in the still video apparatus after various processing, such as composition of the image data, insertion of letters, etc., is performed by the personal computer, so that the recorded picture data can be viewed on the TV screen or printed out. That is, the fixed video device can be used as an external image data memory of

the personal computer.

  In other words, in the first embodiment, since the image data can be input and output, the fixed video apparatus serves as an external data memory for the personal computer and that the images taken by a fixed video camera can be restored after the various image processing have been

  performed by the personal computer.

  It should be appreciated that the present invention is not limited to the above-mentioned embodiment in which a personal computer interface is provided and can be used with a workstation, an available computer, a word processor, a fax machine or other image processing devices

  able to process image data.

  As can be seen from the above, the fact that the fixed video apparatus of the present invention can communicate with an external image processing device not having an interface for image data, it is possible to widen the field

  application of the present invention.

  Application to a fixed video camera.

  The following discussion will be oriented towards a mode

  of implementation applied to a fixed video camera [fig. 5 to 7)}.

  In fig. 6, the fixed video camera comprises a camera body 111 and an image input / output adapter 161 which can be removably mounted on the camera body 111. The camera body 111 is provided on its upper surface with a disc housing 115 in which a magnetic disc 23 (fig. 5} is loaded and a trigger button 117. The camera body 111 includes a lens 119 (fig. 5) placed on its front surface. rear surface of the camera body 111 are placed a viewfinder (an eyepiece thereof) 121, a display panel 123 for indicating the photographic data, function switches 125 which regulate the photographic conditions, the photographic track and the track On a side face of the camera body 111 are placed a connector 127 which serves as an image output terminal and

connection elements 129.

  On the side face of the image input / output adapter 161 are placed a connector 163 which can be connected to the connector 127 of the camera body 111 and connection elements 165 which can be adapted inside or on the connection elements 129 of the camera body 111 to make the image input / output adapter 161 integral with the camera body 111. The connection elements 129 and 165 can be connected so

removable to each other.

  The image input / output adapter 161 is provided on its rear face with function switches 167 which control the transmission and on its opposite lateral face with an interface 169 corresponding to the interface of

the personal computer.

  The following description will apply more

  particularly to the internal circuit construction of the

  fixed video camera shown in fig. 6 (fig. 5).

  An object image to be taken which is formed on an image plane of an image forming device 131 by a lens 119 is converted into image signals (luminance signal and color signal) for each unit of pixel by the image former 131, so that the image signals are supplied to the image signal processing circuit 133 in which the image signals are processed to become an image signal consisting of a luminance signal and a color signal. The image signal is frequency modulated by a frequency modulation circuit 135 and is then amplified by a recording amplifier 137. The amplified image signal is supplied to a magnetic head 141 via a switch selection 139. The image signal is recorded on a predetermined track of the magnetic disc 23 by the magnetic head 141. The image signal processing circuit 133, the frequency modulation circuit 165, the recording amplifier 137 and the magnetic head 141 form a device for recording

image signal.

  The magnetic disc 23 is rotated for a servomotor 143 which is in turn driven by a servo circuit 145. The servo circuit 145 controls not only the rotation of the servomotor 143 but also the alignment of the magnetic head 141, in accordance with the pulse signals from a

coil to PG 149.

  The composite image signals recorded on the magnetic disk 23 are read by the magnetic head 141 and are then output to the reproduction amplifier 151

  via selection switch 139.

  The composite image signals amplified by the reproduction amplifier 151 are demodulated by a frequency demodulation circuit 153 and then are processed to become video signals which are supplied to the image output terminal 139. When a terminal d The image input from a TV screen is connected to the image output terminal 139, the recorded image can be seen on the TV screen. The magnetic head 141, the reproduction amplifier 151, the frequency demodulation circuit 153 and the image signal processing circuit 155 form a device for

reproduction.

  The image signal processing circuits 133 and 155, the switching function of the selection switch 139, the control of the servomotor and of the alignment by the servo circuit 145 are controlled by a system control unit 149. The system control unit 149 usually consists of a microcomputer which generally controls the functions of the components of the fixed video camera in accordance with the

  program stored in the microcomputer ROM.

  The function switches 125 and the trigger switch 117 are connected to the system control unit 149. The system control unit 149 actuates the selection switches 139, positions the recording track or the playback track and sets the photographic mode to take an image and save it in accordance with the operation of the

trigger button 125.

  The display panel 123 indicates information relating to the various functions of the fixed video camera, such as "RECORDING", "REPRODUCING", the recording track or the playback track, or the photographic mode, etc. The lndicatlon

  is controlled by the 149 system control unit. The construction mentioned above is similar to the construction

  a conventional fixed video camera. The following discussion will focus on an image input / output adapter 161 which is one of the most significant features of the present invention. The output of the frequency demodulation circuit 153 is connected to an image output terminal 127a of a

  connector 127 in the form of an external output terminal.

  The control terminal of the system control unit 149

  is connected to a control terminal 127b of connector 127.

  It follows that the image signals (luminance signal and color signal) demodulated by the frequency demodulation circuit 153 are input to the output terminal of Image 127a. The connector 163 of the image input / output adapter 161 comprises an image input terminal 163a and a control terminal 163b corresponding respectively to the

  image input terminal 127a and to control terminal 127b.

  The image input terminal 163a and the control terminal 163b are respectively connected to an A / D converter circuit

  171 and to a digital signal processing circuit 177.

  The output of the A / D converter 171 is connected to a RAM 173, an interface line driver and the digital signal processing circuit 177 through a data bus. The digital signal processing circuit 177 includes a microcomputer which generally controls the functions of the A / D converter circuit 171, the RAM 173 and the line driver

interface 175.

  A luminance signal and a color signal, output from the frequency demodulation circuit 153, are input to an A / D converter circuit 171 through an image output terminal 127a and the output terminal. image entry 163a. The luminance signal and the color signal are converted into digital signals by the A / D converter circuit 171 to be delivered to the RAM 173. That is to say that the luminance signals and the color signals for a single plane d are successively written in RAM 173 as a pixel unit of signals

digital.

  The digital image signals for an image plane written to RAM 173 are processed to become the digital image data signals which can be output to the personal computer. The digital image data signals are then successively read and then supplied to the interface line driver 175 via the data bus. Interface line driver 175 converts digital image signals to predetermined standard transmission signals

  which are delivered to the interface connector 169.

  That is, the image data signals are output from the interface connector 169. As a result, if the interface connector 169 is connected to an interface connector of the personal computer 63, the image recorded on the magnetic disk 23 can be entered to

  the personal computer 63 in the form of image data.

  The reproduction function, as mentioned above, is started by the function switch 137 which is connected to the digital signal processing circuit 177. When the transmission is started by the function switch 137, the digital signal processing circuit 177 delivers the reproduction start signal to the control unit of the system 149 via the control terminals 163b and 127b. The system control unit 149 launches the reproduction function in response to the playback launch signal received in order to read the image signals from an image plane recorded on the magnetic disc 23 through the reproduction device, so that the image signals are supplied from the terminal

  Image output 127a at the image input terminal 163a.

  The image signals input to the image input terminal 163a are converted into image data through the A / D converter circuit 171, RAM 173 and the line interface driver. 175 then

  are output from the interface connector 169.

  The reproduction track is positioned by the function switch 117 of the camera body 111 in the illustrated embodiment. Alternatively, the reproduction track can be positioned by the

  function 167 of the image input / output adapter 161.

  As can be understood from the above, in accordance with the present invention, when the image input / output adapter 161 is mounted on the camera body 111, the recorded image signals can be input to the personal computer in the form of image data. The image input / output adapter 161 can be removed from the camera body 111 in photography

  normal in order to compact the camera.

  In the illustrated embodiment shown in FIG. 5, since the image signals are converted into image data which can be input to the personal computer without passing through the image signal processing circuit 133, the arrangement of the circuit is made simpler than the interface for the image data placed inside the personal computer, so that the number of signal processing steps can be reduced,

  leading to less deterioration of the image signals.

  The present invention is not limited to the Illustrated embodiments mentioned above and can be

variously modified.

  For example, if the output of the image training device 131 is directly connected to the image output terminal 127a, the captured image can be directly input to the personal computer without passing through the

magnetic disc 23.

  If the camera body 111 has a function of recording image signals from an external device, the image input / output adapter 161 can be constructed so as to convert the image data from from the personal computer into image signals which are input to the camera body 111. In this construction, the image processed by the personal computer can be recorded on the magnetic disk 23 and the recorded image can be viewed

  by a TV screen or can be printed.

  In addition, in the case of a fixed video camera in which not only image signals but also audio signals can be recorded, since the image input / output adapter can be removably mounted on the camera body, in accordance with the present invention, a separate adapter which has a sound input / output device incorporated therein can be selectively mounted on the camera body of the fixed video camera in order to enter and exit the audio signals. It is also possible to incorporate the sound input / output device into the image input / output adapter. As can be seen from the

  previous description, the fixed video camera in accordance

  with the present invention can communicate with an external image processing device which does not have a specific interface for image signals by mounting the image input / output adapter of the present invention on the body camera. Removing the image input / output adapter from the camera body makes it possible to

  take an image with a conventional compact camera.
