BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a video tape recorder, with a camera
integrated therein and a video camera. In particular, the invention
relates to a video tape recorder with a camera integrated therein and a
video camera each capable of recording a predetermined title and a voice
associated therewith on a recording medium when an object is shot.
2. Description of the Prior Art
In a VTR with an integrated camera, it has been a common practice that when
an object is shot, a title associated with a scene thereof or a date is
superimposed onto a screen so that the title or the date can be recorded.
For operations to record the title and the date, there has been proposed a
VTR with a camera integrated therein having a so-called superimpose
function in which a title created, for example, by a printing operation is
shot by means of a video camera so as to stored beforehand and the image
thus shot in a memory disposed in the camera. After an operation to shoot
an object is started, the title stored in the memory is read out so as to
be inserted or superimposed onto a screen thus produced. However, in using
such an apparatus each time the operator conducts a shooting operation, it
is necessary to create a title, which hence imposes the problem of
preparing a title production on the operator.
In addition, in the case where the operator selects a desired title from a
plurality of titles thus produced and stored in the memory, it has been
conventionally required to operate three kinds of buttons including a
forward (+) button, a reverse (-) button, and a decision button, for
example; consequently, the title selection has been an extremely difficult
operation.
Furthermore, conventionally, in the case when shooting of an object, a
predetermined voice is desired to be recorded together with an image of
the object on a recording medium, it is required that a tape recorder is
used to effect a playback operation to reproduce a predetermined voice
recorded beforehand on a tape so as to collect the reproduced voice by
means of a microphone disposed in the video tape recorder, thereby
recording the voice together with the image thus shot. In consequence, in
addition to the video tape recorder, a tape recorder is required to be
prepared to generate the voice. This is inconsistent. Moreover, there has
been a problem that during an operation to collect the voice or tone
produced through a playback operation of the tape recorder, an
environmental noise is also recorded on the recording medium.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a video tape
recorder with a camera integrated therein and a video camera each capable
of recording a title and a predetermined voice associated therewith on a
recording medium when an object is shot.
According to the present invention, there is provided a video tape recorder
in which a video signal obtained by imaging an object and an audio signal
gathered for the imaging operation are recorded on a recording medium.
There is a record means for recording the video signal and the audio
signal on the recording medium and title image data store means for
storing therein a plurality of title image data items. Selection data
input means is operated by an operator to input an indication of a title
image data item selected from the plural title image data items stored in
the title image data store means. Control means are used for controlling
said record means and said title image data store means, said control
means being responsive to an indication supplied from the operator by use
of said selection data input means for reading out a selected title image
data item from said title image data store means so as to deliver the
title image data to said record means together with the video signal
developed by imaging the object, thereby enabling the title image data
item to be recorded on the recording medium together with the video signal
developed by imaging the object.
In addition, according to the present invention, there is provided a video
camera which produces a video signal obtained by imaging an object and an
audio signal gathered for the imaging operation comprising title image
data store means for storing therein a plurality of title image data
items. Selection data input means are operated by an operator to input an
indication of a title image data item selected from the plural title image
data items stored in the title image data store means, and control means
are used for controlling said title image data store means. Said control
means being responsive to an indication supplied from the operator by use
of said selection data input means for reading out a selected title image
data item from said title image data store means, thereby enabling the
title image data item to be produced together with the video signal
developed by imaging the object.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, description will be given of an embodiment
according to the present invention.
FIG. 1 shows an embodiment in which the present invention is applied to a
video tape recorder including a camera integrated therewith. In this
embodiment, a video tape recorder having a camera integrated therewith 100
hias an imaging function, an image recording function, and a playback
function. The video tape recorder 100 comprises a digital title memory 34
for storing therein a plurality of titles and a digital voice memory 16 in
which voice or audio data associated with the titles are stored. In this
apparatus, a title selected in response to a title selection conducted by
the operator from the titles stored in the digital title memory 34 is
inserted into an imaged screen; furthermore, a music piece or a voice
associated with the title is read from the voice data stored in the
digital voice memory 16 so as to be recorded on a video tape together with
the title at the same time.
There is disposed an imaging section 10 including a lens of an optical
system and a solid-state imaging device, not shown, such as a
charge-coupled device such that in response to control signals from a
system controller 20, an optical image of an object focused through the
lens is converted into a video signal so as to produce a composite video
signal of the standard color television format including a luminance
signal, a color difference signal, and a synchronizing signal, which is
then transmitted to a digital titler section 12.
The digital titler 12 is connected to the digital title memory 34 storing
therein fixed titles in the form of digital data, for example, "Wedding
Ceremony", "Athletic Meeting", "Children's Day", "Christmas Party", and
"the New Year" associated with occasions where objects and object scenes
are to be frequently shot.
Moreover, the digital titler section 12 is connected to the imaging section
10, a recording section 14, and the system controller 20. Based on a title
indicate signal received from the system controller 20, the digital titler
12 reads out an indicated title from the plural fixed titles stored in the
digital title memory 34 such that a signal of the title is mixed with the
video signal supplied from the imaging section 10 and that the resultant
signal is sent to the recording section 14, thereby displaying the title
superimposed onto the picture represented by the video signal. The mixed
signal from the digital titler 12 is also delivered to an electronic
viewfinder, EVF 32 so that the title is superimposed onto the imaged
picture displayed on the electronic viewfinder 32.
In the digital voice memory 16, there are stored appropriate music pieces
associated with the respective titles stored in the digital title memory
34, for example, "Seikurabe (Japanese Children's song)" for the fixed
title "Children's day", and "Jingle Bells" for the fixed title "Christmas
party".
The video tape recorder 100 includes a microphone 26, an amplifier 28 for
amplifying an audio signal supplied from the microphone 26, and an
analog-to-digital, AD converter 30 for converting the audio signal from
the amplifier 28 into a digital signal. The analog-to-digital converter 30
produces an output, which is connected to the digital voice memory 16 and
the recording section 14.
A digital voice playback section 18 is responsive to a control signal from
the system controller 20 so as to read out specified data from the music
pieces or voice or audio data stored in the digital voice memory 16,
thereby effecting a playback on the data. The reproduced signal is sent to
the recording section 14.
The recording section 14 modifies the video signal received from the
digital titler 12 and the audio signal supplied from the digital voice
playback section 18 into a signal to be recorded on a video tape and
delivers the obtained signal to a tape recording mechanism 24. The tape
recording mechanism 24 includes a tape drive mechanism such as a rotary
head cylinder and a motor necessary to record the video and audio signal
on a video tape and a tape install section in which the video cassette
tape is to be mounted. The mechanism 24 is driven according to a control
signal supplied from the system control section 20.
The recording section 14 is responsive to a control signal delivered from
the system control section 20 to supply the tape drive mechanism 24 with
the video signal which is generated by the imaging section 10 and which is
mixed with a fixed title in the digital titler 12. The tape recording
mechanism 24 records the video signal via a video head onto a video track
of a video cassette tape installed in the tape install section. In
addition, a recording signal of the voice fed from the digital voice
playback section 18 is recorded via an audio signal recording head onto an
audio track of the video cassette tape.
The system control section 20 is advantageously constituted with a
microcomputer, CPU and is connected to the imaging section 10, the
operating section 22, the tape recording section 24, and the digital voice
playback section 18. The system controller 20 supplies the respective
sections of the video tape recorder 100 with various control signals
depending on the connection states of the switches disposed in the
operator's console 22.
The operating section 22 is arranged in an outer surface of a casing of the
video tape recorder 100 with a camera integrated therein as shown in FIG.
2 and includes a record switch for inputting indications of initiation and
termination of the recording operation, a title select switch 52 for
selecting a fixed title stored in the digital memory of the digital titler
12, and a title record switch 54 for recording a selected title.
Incidentally, the title select switch 52 has a function to indicate two
operations. Namely, a first function is employed to supply an indication
to output the menu of a fixed title from the digital memory of the digital
titler 12 onto the electronic viewfinder 32, whereas a second function is
adopted to select a title from the title menu displayed on the electronic
viewfinder 32.
These switches are operated by the operator who effects a shooting
operation.
The electronic viewfinder 32 has a small-sized Braun tube so as to receive
a video signal supplied from the imaging section 10 via the digital titler
12 or a video signal mixed with a fixed title from the digital titler 12,
thereby displaying a resultant picture.
Next, description will be given of operatios of the video tape recorder 100
with a camera integrated therein.
Referring to FIGS. 3 and 4, there is shown an example of the case where a
title and a music piece associated therewith are inserted into an imaged
picture so as to record a resultant image on a recording medium.
When the operator turns the main power of the video tape recorder 100 on,
the system control section 20 delivers a control signal to the imaging
section 10, which then converts an optical image of an object focused
through the lens into a video signal, produces therefrom a composite video
signal conforming to the standard color television format, and then
supplies the resultant video signal to the digital titler 12. The
composite video signal is transmitted via the digital titler 12 to the
recording section 14 and to the electronic viewfinder 32. This operation
is continuously achieved until the main power is turned off regardless of
the connection state of the recording switch 56.
As shown in FIG. 3, when the title selection switch 52 of the operator's
panel 22 is set to ON by the operator, the system controller 20 sends a
control signal to the digital titler 12 so as to call for a menu of fixed
titles stored in the digital memory of the digital titler 12, thereby
displaying the menu on a display screen 80 of the electronic viewfinder
32. In this situation, a cursor 82 is indicated at either one of the fixed
titles to enable the operator or user to select a title. Thereafter, when
the operator activates the title selection switch 52, the sytem control
section 20 shifts the cursor 82 downward by a title line on the display
screen 80. In consequence, the user operates the switch 52 until a title
to be inserted into the imaged screen appears on the screen and selected.
For example, in the case where the operator desires to select a title
"Children's Day", the switch 52 is operated until the cursor 82 comes to
the position of the "Children's Day".
When the record switch 56 is activated, the system controller 20 controls
the recording section 14 and the tape recording mechanism 24 to initiate a
recording operation of the image onto the video cassette tape.
When the title record switch 54 is additionally operated, the system
controller 20 sends a control signal to the digital titler 12, which
inturn converts digital data of the title "Children's day" thus selected
into analog data through a digital-to-analog conversion so as to mix the
converted recording signal with a video signal supplied from the imaging
section 10. The mixed video signal is fed via the recording section 14 to
the tape recording mechanism 24 so as to be recorded via the video head
onto a video track of a video cassette tape installed in the tape mount
section.
In this situation, the system controller 20 also supplies a control signal
to the digital voice playback section 18, which then reads out data of a
music piece associated with the title "Children's Day" from the data of
music pieces stored in the digital voice memory 16 such that the obtained
data undergoes a playback operation to produce an audio signal to be
transmitted to the recording section 14. The audio signal is converted
into a recording signal in the recording section 14 and is then sent to
the tape recording mechanism 24 so as to be recorded on an audio track of
the video cassette tape mounted in the tape install section.
Incidentally, the title is recorded on the video cassette tape so as to be
displayed on the screen before the music piece associated therewith is
finished, so that the recording of the title is completed when the music
performance is terminated. In addition, as shown in FIG. 4, while a title
and a music piece are being recorded on a tape, the title is supplied to
the electronic viewfinder 32 so that a musical note symbol 84 indicating
the performance of the music piece is displayed on the display screen 80.
A voice or tone of the music piece is delivered to an earphone terminal,
not shown, which enables the user to confirm the playback of the music
piece.
As described above, a title and a music piece corresponding thereto are
recorded on a video cassette tape together with a image signal.
In short, the video tape recorder 100 having a camera integrated therewith
according to the present invention is provided with the digital title
memory 34 for storing therein a plurality of fixed titles and a digital
voice memory 16 in which music pieces corresponding to the respective
fixed titiles or voices beforehand stored in association therewith are
stored. When the title selection switch 52 and the title recording switch
54 are operated for connections thereof, a title menu is displayed on the
electronic viewfinder 32; thereafter, when the operator selects a title of
the menu, a music piece or a voice associated with the selected title is
recorded on a video cassette tape together with the title at the same
time.
In consequence, while the operator is recording an object by visually
checking an image thereof through the electronic viewfinder 32, through an
operation to activate the title selection switch 52 and the title
recording switch 54, a desired title can be easily inserted into an
obtained scene in which the title is to be displayed; furthermore, a music
piece or a voice associated with the selected title is recorded on a video
cassette tape together with the title at the same time.
Incidentally, when the recording of the music piece or the voice associated
with the title is completed in the video tape recorder 100 having a camera
integrated therewith according to the present invention, there is
naturally conducted a normal recording by means of an external microphone
58 mounted on the video tape recorder 100; moreover, while a title is
being recorded on a tape, it is possible to simultaneously effect the
recording of a music piece or a voice and the recording operation through
the external microphone 58.
In addition, in the video tape recorder 100 according to the present
invention, when a title is selected, a music piece or a voice associated
with the selected title is recorded on a video cassette tape at the same
time; moreover, it is also possible to provide a selecting function so as
to record only the title or only the musicpiece or voice on the recording
medium.
Furthermore, if the video tape recorder 100 according to the present
invention is provided with the conventional superimpose function described
above, namely, a function in which a title beforehand shot by the operator
and recorded in a memory is inserted into a produced image screen, it is
possible to implement a camera having a broader applicability.
Moreover, according to this embodiment, although the digital title memory
34 and the digital voice memory 16 are installed in the video tape
recorder 100 with a camera integrated therein, the apparatus may also be
configured such that the apparatus is provided with a connector section
for connecting an external memory to the apparatus so as to store the
plural fixed titles and voice data associated therewith respectively
stored in the digital title memory 34 and the digital voice memory 16 and
that the external memory is then connected to the connector section,
thereby developing the function above.
Although the description of the present invention has been given with
reference to the embodiment in an example of a video tape recorder 100
with a camera integrated therein, the present invention is applicable to,
in addition to the VTR having an integrated camera, a video camera of a
separated type, a disk camera, and other cameras.
According to the present invention, since the video tape recorder 100 with
a camera integrated therein is provided with title image data store means
for storing therein image data of a plurality of titles and voice data
store means in which voice data associated with these titles are stored,
it is possible for the user to insert a desired title through a simple
operation when a video signal is recorded; furthermore, the voice can be
inserted together with the title.
While the present invention has been described with reference to the
particular illustrative embodiments, it is not to be restricted by those
embodiments but only by the appended claims. It is to be appreciated that
those skilled in the art can change or modify the embodiments without
departing from the scope and spirit of the present invention.
