`1994 issue of the "Photographic Industries" magazine, pages
`12 to 15, describes an image recording apparatus which is
`capable of both recording a silver salt picture and recording
`an image signal.
`[0005] To achieve a more advanced versatility, an image
`shooting apparatus is desired to have, in addition to the
`above described conventional functions, a various modes of
`operation, such as a mode in which silver salt shooting and
`video movie shooting can be performed simultaneously, a
`mode for reproducing a video, a mode for shooting a
`still-picture video, an edit mode for editing information
`recorded on a silver salt film and other modes.
`[0006] However, since such an image shooting apparatus
`has various and complicated functions, it is necessary to
`indicate on a display such as a viewfinder what operation is
`currently being performed and what are the current states of
`the items needed for editing, such as individual identifica-
`tion number, frame number, date, time, print aspect ratio,
`whether or not in process of movie recording, and other
`items, so that such information is notified to the user and
`recorded on a recording medium.
`
`[0007] In this case, when still-image shooting is per-
`formed during video movie shooting, for example, the
`apparatus is expected to be capable of searching for still-
`picture shooting information during reproduction. Accord-
`ingly, in order for the user to recognize the existence of the
`still-picture on a recording medium, the apparatus is also
`expected to be capable of displaying the still-picture shoot-
`ing information in a display unit.
`[0008] In one conventional image shooting apparatus,
`reproduction conditions are changed at the recording by
`index data recorded in a data area of a recording medium so
`that a reproduced screen can be automatically changed from
`a normal screen to a wide screen according to the index data
`recorded in a data area secured in a recording medium.
`[0009] However, in the conventional apparatus, reproduc-
`tion conditions are changed according to the data from the
`data area indeed, but only to change the screen from the
`normal screen to the horizontally extended wide screen.
`Accordingly, even though it is possible to display a still
`picture in the display unit, it is not possible to display
`still-picture shooting information by use of the automatic
`normal/wide screen switching function.
`[0010] Another conventional image shooting apparatus
`performs a date search, that is, it searches the data area for
`a turning point of date to reproduce the portion starting from
`the turning point for around 10 seconds for a searching
`purpose.
`
`[0011] However, in the conventional apparatus, it is not
`possible to display still-picture shooting information by use
`of the function for searching for a turning point of date to
`reproduce the portion starting from the turning point for a
`while for a searching purpose.
`[0012] To achieve information display, in a conventional
`video camera, the index data recorded in a data area secured
`on a recording medium is recorded in one portion at the top
`of a DAT (Digital Audio Tape system) tape.
`[0013] However, in this conventional camera, since the
`index data is placed in one portion at the top of a DAT tape,
`it is possible to efficiently retrieve shooting information
`indeed, but it is not possible to perform silver salt shooting,
`because a function as a still camera is not provided. Accord-
`ingly, even if the above described method is applied to an
`image shooting apparatus functioning as both a video cam-
`era and a still camera, it is not possible to record shooting
`information on a silver salt picture.
`
`[0014] In such an image shooting apparatus which func-
`tions as both a still camera and a video camera, it is often
`necessary to confirm shooting records by contrasting still
`pictures and a video picture immediately or in a certain time
`lag after shooting. It is also necessary to record information
`representing a relationship between the still pictures and the
`video picture as a database after shooting.
`[0015] As a conventional example, Japanese Laid-Open
`Utility Model No. S63-192773 and Japanese Laid-Open
`Patent No H5-75902 disclose an image shooting apparatus
`in which only frame numbers of a silver salt film are mixed
`as a character signal into an image signal. Moreover, Japa-
`nese Laid-Open Patent No. 3-27173 discloses a camera
`equipped with an electric display device functioning also as
`a viewfinder, in which only release viewing can be per-
`formed by use of the electric display device.
`[0016] However, in the former image shooting apparatus,
`in order to cope with the case where a plurality of silver salt
`films are used simultaneously with one magnetic tape serv-
`ing as a image recording medium, only frame numbers of a
`silver salt film is mixed as a character signal with an image
`signal, and the frame numbers are superimposed on the
`image signal when displayed. Accordingly, it is difficult to
`retrieve entries in the database and, in particular, to cope
`with the case where a silver salt film is exchanged at its
`midpoint leaving the remaining portion unused. Moreover,
`in the latter camera, since it does not have a function as a
`video camera, an image signal cannot be recorded.
`
`SUMMARY OF THE INVENTION
`[0017] An object of the present invention is to provide an
`image shooting apparatus with a still camera which is
`provided with a function for displaying still-picture shooting
`information in a display unit when it is necessary to search
`a recording medium for still-picture shooting information
`during reproduction in the case where still-picture shooting
`is performed during video movie shooting.
`[0018] Another object of the present invention is to pro-
`vide an image shooting apparatus with a still camera in
`which shooting information of silver salt shooting is
`recorded in one place as index data.
`[0019] Still another object of the present invention is to
`provide an image shooting apparatus functioning as both a

`
`still camera and a video camera, in which entries of a
`database can be easily retrieved.
`[0020] To achieve the above object, one aspect of an
`image shooting apparatus of the present invention is pro-
`vided with a silver salt picture shooting section having a
`silver salt picture recording function and a silver salt infor-
`mation recording function, a video picture shooting section,
`a video signal recording section for recording a video signal
`obtained by the video picture shooting section and video
`information on the recording medium, a video signal repro-
`duction section for reproducing the video signal and video
`information from the recording medium, an electric display
`device for displaying the video picture and video informa-
`tion reproduced by the video signal reproduction section, a
`shooting information provider for outputting various items
`of information as to shooting, and an information input
`section for inputting the various items of information into
`the shooting information provider by the video signal
`recording section.
`[0021] According to the above construction, it is possible
`to record silver salt information when a silver salt picture is
`recorded, whereas it is also possible to record video infor-
`mation when video signal is recorded. The silver salt infor-
`mation thus inputted during recording can be displayed on
`the electric display device. For example, when silver salt
`picture shooting is performed during video movie shooting,
`the thus shot image can be displayed as a still image during
`reproduction of the video, with reproduction conditions
`being varied in accordance with the data from the data area.
`Consequently, it is possible to observe an image of silver salt
`shooting before developing the image, by searching for,
`extracting and then reproducing data of the still image of the
`time when silver salt shooting was performed.
`[0022] According to another feature of the present inven-
`tion, the image shooting apparatus of the present invention
`is provided with a silver salt picture shooting section having
`a silver salt picture recording function and a silver salt
`information recording function, a video picture shooting
`section, a video signal recording section for recording a
`video signal obtained by the video picture shooting section
`and video information, a silver salt film individual identifi-
`cation number/frame number provider for outputting an
`individual identification number and a frame number of a
`silver salt film used as a recording medium for the silver salt
`picture shooting section, and an index data recording section
`provided separately from the video signal recording section
`for recording index data which is an aggregate of shooting
`information during silver salt shooting.
`[0023] According to the above construction, it is possible
`to record silver salt information when a silver salt picture is
`recorded, whereas it is also possible to record video infor-
`mation when video signal is recorded. Since the silver salt
`information thus inputted during recording is recorded in the
`index data recording section, the silver salt information can
`easily be retrieved by searching the index data recording
`portion. Accordingly, it is not necessary to search a film or
`a recording medium from end to end in order to retrieve
`silver salt information.
`[0024] According to still another feature of the present
`invention, the image shooting apparatus is provided with a
`silver salt picture shooting section including a silver salt
`picture recording means and a silver salt information record-
`
`ing means, a video signal recording section including a
`video signal recording means and a video information
`recording means, and a silver salt film individual identifi-
`cation number/frame number output means for outputting an
`individual identification number and a frame number to a
`silver salt film used as a recording medium of the silver salt
`picture shooting section.
`
`[0025] According to the above construction, it is possible
`to record silver salt information when a silver salt picture is
`recorded, whereas it is also possible to record video infor-
`mation when video signal is recorded. Simultaneously with
`recording, a silver salt film individual identification number
`and a frame number are additionally inputted. This makes it
`possible to record the individual identification number on
`the silver salt film, so that images taken by the still camera
`can be observed as image signals immediately or in a certain
`time lag after shooting, and so that information representing
`relationships between the still pictures and the video picture
`can be recorded as a database after shooting. Further, in
`contrast to a conventional construction where frame num-
`bers are superimposed on the image signal, the individual
`identification number and the frame number are recorded as
`an information signal into the image signal, so that entries in
`the database can be easily retrieved.

`
`DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`[0061] Hereinafter, an embodiment of the present inven-
`tion will be described with reference to the drawings. FIG.
`1 schematically shows the structure of the embodiment. As
`shown in FIG. 1, the image shooting apparatus according to
`the present embodiment includes a camera body C, a main
`lens L, and a lighting and flashing unit F (hereinafter
`referred to as "flash-and-light"). The video shooting optical
`system and the sliver salt (silver halide) shooting optical
`system, which will be described later, are formed of com-
`mon structural members.
`
`[0062] In the following description of the embodiment, for
`easier reference between the description and the drawings,
`the reference designations of the components of the camera
`body C begin with C, those of the main lens L begin with L,
`those of the flash-and-light F begin with F, and those of the
`operation unit COP provided in the camera body C begin
`with COP.
`[0063] Although the main lens L and the flash-and-light L
`are constructed separately from the camera body C in this
`embodiment, the present invention includes a structure in
`which the camera body C and the main lens L, the camera
`body C and the flash-and-light F, or these three portions are
`formed as one unit. The video shooting optical system and
`the silver salt shooting optical system may be formed
`separately from each other.
`
`[0064] FIG. 2 schematically shows the structure of the
`optical system of this embodiment. In FIG. 2, light from a
`subject passes through the main lens L, and has its quantity
`controlled by a main lens aperture diaphragm Lll. Then, the
`light is split by a pellicle mirror C04 into a first light path
`leading to a film C08 when a shutter C07 opens and a second
`light path branching off from the first light path in the
`pellicle mirror C04 and leading through a condenser lens
`CIO, a reflecting mirror C11 and an ND filter C13 to a relay
`lens C14. AX represents an optical axis extending from the
`subject toward the main lens L.
`
`[0065] The light coming from the subject and having been
`directed along the second light path toward the relay lens
`C14 has its quantity controlled by a relay aperture dia-
`phragm C18, travels through an optical low-pass filter C16
`and an infrared ray (IR) cut filter C17, and then reaches a
`CCD (charge coupled device) image sensor C21, which
`serves as a photoelectric converter. Although the CCD
`image sensor C21 shown in FIG. 2 is of a single-plate type,
`a CCD image sensor of a multiple-plate type may be used.
`
`[0066] The first light path is a light path for still shooting
`by use of a silver salt film. The second light path is a light
`path for movie shooting by use of a video recording
`medium. As shown in FIG. 1, silver salt shooting sections
`C06 to C09 and video signal shooting sections C21 to C27
`are provided in the camera body C.

`
`[0067] First, the structure of the main lens L will be
`described below, with reference to FIG. 1. L01 and L03
`represent operation rings manually operated by the user. L01
`represents a focusing operation ring and L03 represents a
`zooming operation ring. L13 represents a stationary barrel.
`L02 and L04 represent operation ring condition detectors
`which detect rotation of the operation rings L01 and L03,
`respectively. Typically, the detectors L02 and L04 comprise
`encoders.
`
`[0068] L05 represents a focal length detector for detecting
`the focal length of the main lens L. L06 represents a lens
`microcomputer serving as a operational controller of the
`main lens L. L07 represents a zooming motor for zooming
`the main lens L. LOB represents a zooming motor monitor
`for detecting the rotation condition of the zooming motor
`L07. The monitor L08 comprises, for example, a photo-
`interrupter.
`
`[0069] L09 represents a focusing motor for focusing the
`main lens L. L10 represents an AF/MF switching button for
`switching between automatic focusing and manual focusing.
`L11 represents a main lens aperture diaphragm. L12 repre-
`sents a main lens aperture diaphragm controller. The main
`lens aperture diaphragm controller L12 includes a stepping
`motor for actuating the aperture diaphragm, and an aperture
`condition detector.
`
`[0070] The focusing and zooming operation rings L01 and
`L03 are fitted on the peripheral surface of the stationary
`barrel L13 to be rotatable about the optical axis of the main
`lens L. Rotation of the focusing operation ring L01 activates
`power focusing. Rotation of the zooming operation ring L03
`activates power zooming.
`
`[0071] Next, the structure of the camera body C will be
`described below. C01 represents a camera microcomputer
`serving as a operational controller of the camera body C. The
`camera microcomputer C01 exchanges information with the
`main lens L through data/power-supply contacts C30. As to
`the flash-and-light F, the camera microcomputer C01
`exchanges information with the operational controller F01
`of the flash-and-light F through contacts provided in an
`accessory shoe C20. The external view of the shoe C20 for
`attaching an external flash-and-light is shown in FIG. 3.
`
`[0072] C05 represents an AF auxiliary mirror provided at
`the rear of the above-mentioned pellicle mirror C04. The
`subject light having passed through the main lens L is split
`by the pellicle mirror C04, and then travels along the first
`light path until further split by the AF auxiliary mirror C05
`and directed to a focus detector CO2. The focus detector CO2
`transmits focus information to the camera microcomputer
`CO. The focus information processed by the camera micro-
`computer C01 is transmitted to the lens microcomputer L06,
`which then issues a command for driving the focusing motor
`L09 to perform focusing.
`
`[0073] C06 represents a shutter driver which opens and
`closes the shutter C07 in response to a command from the
`camera microcomputer C01. More specifically, the camera
`microcomputer C01 issues a command signal to the shutter
`driver C06 based on information from the operation unit
`COP, a brightness detector C12 and others. C08 represents a
`film, whose surface is exposed to the light having travelled
`along the first light path through the opening created by the
`releasing of the shutter C07 so that a latent image of the
`
`subject is formed thereupon. C09 represents a film advanc-
`ing controller for driving an incorporated motor to wind and
`rewind the film.
`
`[0074] The light split by the pellicle mirror C04 and
`having travelled along
