Also, the door 1 on the back side of the grip part
By opening 6, the power supply battery can be replaced.

In FIG. 1, which shows an outline of the electric configuration of the still camera 1, the operation of the still camera 1 is performed by a photographic camera controller 20 and a digital camera controller 22.
Is controlled by These controllers 20, 22
Is composed of a CPU, which is a main component of the microcomputer.
According to a sequence program written in the OM 23, a series of operations required for photographing is controlled. The digital camera controller 22 exchanges control signals and data with the photographic camera controller 20, and also controls the operation when the image sensor captures a subject image in accordance with a sequence program in the program ROM 23.

The photographic camera controller 20 includes an exposure control circuit 24, a lens moving mechanism 25, and a film feeding mechanism 2.
6. Control the operation of the magnetic recording / reproducing circuit 27. For controlling these operations, signals obtained from a photoelectric perforation sensor (hereinafter, referred to as a PF sensor) 30 and an external sensor input unit 31 are referred to, and signals from an operation input unit 32 such as a shutter button 7 and a key input unit 14 are referred to. Is referred to.

The exposure control circuit 24 includes an external sensor input unit 31
The opening and closing of the program shutter 34 is controlled based on the photometric data from. The photometric data has a value corresponding to the subject luminance measured through the photometric window 6. The lens moving mechanism 25 performs zooming of the photographing lens 3 based on a zoom operation signal from the operation input unit 32, and focuses the photographing lens 3 based on distance measurement data from the external sensor input unit 31. The distance measurement data has a value corresponding to the object distance measured by the projection / reception units provided on both sides of the finder objective window 4. Note that zooming is performed not only on the photographing lens 3 but also on the finder optical system 36 provided behind the finder objective window 4.

The film feeding mechanism 26 feeds one frame of the photographic film 8a every time the photographing is completed. IX-24
Since the photographic film 8a used in the 0-type photographic film cartridge has two perforations per frame, the PF sensor 30 detects the passage of the perforations by detecting the passage of the perforations. can do. By counting the detection signals obtained for each frame feed, the number of frames to be shot can be determined. The number of shot frames is sequentially updated in the RAM 29,
It is used as information for a frame number counter, and is used as frame number information when writing image data described later.

A transparent magnetic recording layer is applied to the entire back surface of the photographic film 8a. Then, the magnetic recording / reproducing circuit 27 supplies a recording signal to the magnetic head 35 during the one-frame feeding after the photographing is completed, whereby the magnetic head 35 moves the photographing frame out of the photographing screen of the photographing frame. The additional information related to the photographic image of the frame is written. This additional information includes, in addition to exposure data such as the shutter opening / closing time and the presence / absence of strobe shooting, shooting date / time data, designation data for designating a print size, the number of prints, and a title. These data are written after being converted into binary signals for magnetic recording by contrast with the data ROM 36.

The magnetic head 35 is also used for reproduction, and the read binary signal is decoded by the photographic camera controller 20 in contrast to the data ROM 36. At the head of the photo film 8a, an ID code attached to the photo film cartridge 8 is magnetically recorded in advance. Then, after the photographic film cartridge 8 is loaded into the camera, the ID code is read when the film is automatically fed to set the first frame on the exposure aperture, and is written into the RAM 29. In addition, a photoelectric bar code reader is provided in the loading chamber of the photo film cartridge 8, and the ID is transmitted from the bar code 10a.
A code may be read.

An area type image sensor 39 is provided on the image forming surface of the finder optical system 38. Since the finder optical system 36 has a short focal length and the image sensor 39 has a resolution of about 200,000 to 400,000 pixels, the finder optical system 38 does not need to be focused. Also, it is possible to capture a subject image that is almost satisfactory within the depth of focus. The driving of the image sensor 39 is performed by the sensor driver 40 under the control of the digital camera controller 22.

Under the control of the digital camera controller 22, the charge accumulation time of the image sensor 39 is feedback-controlled through an image signal processing circuit 41, an A / D converter 42, and an image data processing circuit 44, which will be described later. It is automatically adjusted in accordance with this, but photometric data from the external sensor input unit 31 can be used for this control.

An image signal from the image sensor 39 is input to an image signal processing circuit 41. Imaging signal processing circuit 41
Performs an R, G, B color separation after amplifying an image pickup signal to an appropriate level by an automatic gain controller or the like.
The image signal for each color is digitally converted by the A / D converter 42 and then input to the image data processing circuit 44. The image data processing circuit adjusts white balance,
Image data for one screen is created by performing signal processing such as matrix operation. By sending the image data for one screen to the LCD driver 45 one after another, the finder image is displayed on the liquid crystal display monitor 12 as a moving image.

The buffer memory 46 has a shutter button 7
The image data at the time when the photograph was taken by the operation described above is stored for one screen. The image data thus stored is processed by the image data processing circuit 44 for I / O control I / O.
The data is written in a built-in memory 48 built in the camera via an / O port 47 in advance. When writing this image data, the photo camera controller 20
From M29, an identification code consisting of an ID code and a frame number of the photo film cartridge 8, and additional information such as designated data and exposure data preset at the time of photographing are read. Then, these pieces of information are transmitted to the image data processing circuit 44 via the digital camera controller 22 and written into the built-in memory 48 together with the image data.

As described above, under the control of the digital camera controller 22, the image data processing circuit 44 not only functions as a means for converting an image pickup signal into image data, but also writes image data into the buffer memory 46, It also functions as data recording means for writing the identification code into the built-in memory 48. The built-in memory 48
380,000 pixel image sensor 3
The image data obtained from the image data 9 can be photographed on the photographic film 8a by applying standard quality JPEG compression to the image data 40.
The size is set to, for example, 2 MB to 4 MB in accordance with the maximum number of frames (for one photo film).

The font ROM 50 stores font data for displaying characters and marks on the liquid crystal display monitor 12. Then, for example, the liquid crystal display monitor 1
In order to display the number of frames taken on the photo film 8a in the photo film controller 2, the photo camera controller 20
The frame number is read from 9 and transmitted to the digital camera controller 22. Digital camera controller 2
Reference numeral 2 denotes a font ROM 50, which captures font data for displaying a frame number.
Enter 4 The image data processing circuit 44 supplies the input font data to the LCD driver 45 together with the image data. Thereby, the frame number is displayed on the liquid crystal display monitor 12 together with the finder image.

Similarly, various kinds of information can be displayed on the liquid crystal display monitor 1.
2 can be displayed. In a camera using a IX-240 type photo film cartridge, the standard size of a photo print is a high definition size (89 mm × 15 mm).
8mm), but also panoramic size (89mm x 254mm) or C size (89mm)
(* 127 mm) print service is also possible. The print size is determined by the user, but when the key input unit 14 specifies the print size at the time of photographing, the font data for masking corresponding to the specified size is read out and displayed on the liquid crystal display monitor 12. By doing so, the range to be printed can be confirmed in advance on the finder screen (see FIG. 6).

The operations of the photographic camera controller 20 and the digital camera controller 22 are controlled by operation of the key input unit 14 or key input operation from a personal computer connected via the connector 15 irrespective of photographing. can do. Therefore, for example, image data can be transferred bidirectionally between the hard disk of the personal computer and the built-in memory 48, or the developed photographic film 8 can be transferred.
Only when “a” is loaded, the film can be fed to an appropriate frame position, and the information recorded on the magnetic recording layer at an arbitrary frame position can be read.

The operation of the still camera 1 will now be described with reference to the flowchart of FIG. Open / close lid 9
Is released and the photographic film cartridge 8 is loaded into the cartridge chamber in the camera body 2. Thereafter, when the cover 9 is locked in the closed position, the light blocking cover opening / closing mechanism incorporated in the camera operates to open the light blocking cover closing the film entrance of the cartridge 8b. Subsequently, the film feeding mechanism 26 operates to drive the spool of the cartridge 8b in the film feeding direction, and sends out the photographic film 8a from the cartridge 8b.

When the PF sensor 30 detects that the perforation of the first frame has moved to a predetermined position, the operation of the film feeding mechanism 26 is stopped and the first frame is stopped.
The frame is set in the exposure aperture. During the initial feeding period of the film, the magnetic head 35 moves the photographic film 8.
Information is read from the magnetic recording layer a. The read information includes an ID code commonly assigned to the photo film 8a and the cartridge 8b, the type of the photo film 8a, and the number of shots.

The information read from the magnetic recording / reproducing circuit 27 is decoded by the photo camera controller 20.
The data is written to the RAM 29. Information on the type of the photo film 8a and the number of shots can be used for controlling the exposure of the photo camera and setting the upper limit of the number of shots counter. The ID code is used when recording image data in a memory as described later.

When the liquid crystal display monitor 12 is erected and the power switch 13 is turned on, the sensor driver 40 operates according to a command from the digital camera controller 22 to start capturing a subject image. Image sensor 39
Is input to an image data processing circuit 44 via an imaging signal processing circuit 41 and an A / D converter 42 to generate image data. This image data is supplied to the liquid crystal display monitor 12 via the LCD driver 45, and the liquid crystal display monitor 12 displays the subject image. Under the control of the digital camera controller 22, the imaging and display of the subject image are performed sequentially, so that the user can perform framing while observing the display image on the liquid crystal display monitor 12.

To set designated data such as the print size and the number of prints, the additional information setting key of the key input unit 14 is operated. Thereby, the initial setting of the designated data is displayed on the liquid crystal display monitor 12. In this initial setting, for example, the print size is H size, the number of prints is 1,
The title is pear, and these designated data 56
Is superimposed on the subject image and displayed on the liquid crystal display monitor 12 as shown in FIG.

Items that can be changed include an arrow-shaped cursor 57.
Is displayed, the cursor-moving key of the key input unit 14 is operated to move the arrow-shaped cursor 57 to the designated data to be changed. For example, if the designated data to be changed is “print size”, the arrow-shaped cursor 57 is moved to “print size”, and then the enter key of the key input unit 14 is pressed. The characters "H", "C", and "P" are arranged in the vertical direction, and the other designated data is not displayed (B). This time, the arrow cursor 58 is displayed on the right side of “H”, “C”, and “P”, so that the cursor movement keys are operated to move the arrow cursor 58 to “H”, “C”, and “P”. Adjust to one.

When the arrow-shaped cursor 58 is moved to "H", a screen corresponding to the high definition size as it is initially set is displayed on the liquid crystal display monitor 12 (A). When the arrow cursor 58 is moved to "C", the font RO
The masking format data is called from M50, a pair of C masks 61 are displayed on the left and right ends of the screen of the liquid crystal display monitor 12, and the conventional size print range is displayed (B). Similarly, the arrow-shaped cursor 58 is moved to “P”
, A pair of P masks 62 are displayed at the upper and lower ends of the screen of the liquid crystal display monitor 12, and a panoramic size print range is displayed (C). These masks 61, 6
Numeral 2 is, for example, a semi-transparent gray so that the lower subject image can be seen through.

When the desired print size, for example, the conventional size is displayed, the movement of the arrow-shaped cursor 58 is stopped and the enter key of the key input unit 14 is pressed. Thereby, a pair of C
Except that the application mask 61 is still displayed on the left and right edges of the screen, the screen becomes the screen on which the other designated data 56 is displayed, as in (A). To set a title, similarly to the print size setting, when the arrow-shaped cursor 57 is moved to "Title" and the enter key is pressed, a plurality of titles are displayed. Cursor 5
What is necessary is just to press 8, and to press the decision key.

In order to set the number of prints,
When the cursor 57 is moved to "number of prints" and the enter key is pressed, the number next to "number of prints" blinks. When the cursor movement key is operated in this state, the number is increased by an upward operation, and the number is decreased by an downward operation. When the enter key is pressed while a desired number is displayed, the number changes from a blinking state to a normal display state. After the print size, title, and number of prints have been specified in this manner, if the arrow-shaped cursor 57 is positioned on the <setting end> 56a on the screen and the enter key is pressed, the specified data 56 is hidden, and these specifications are hidden. Data is in RAM 29
Is written to. As will be described later, these designations can be changed even after all photographing is completed and the photo film 8a is developed, and the designation operation does not have to be forcibly performed. When the designation operation is not performed, the designated data 56 of the initial setting is written in the RAM 29 as it is.

When the shutter button 7 is operated for photographing, the photographing lens 3 is focused by pressing the shutter button halfway, and the distance measurement data at that time is input to the exposure control circuit 24. When the shutter button 7 is fully depressed, the exposure control circuit 24 opens and closes the program shutter 34 to take a picture. The full-press signal of the shutter button 7 is also input from the photographic camera controller 20 to the digital camera controller 22, and in response thereto, image data for one screen taken at that time is transferred to the buffer memory 46. .

After the operation of the program shutter 34 is completed, the photo camera controller 20 operates the film feeding mechanism 26 to perform a film one frame feeding process. During this one-frame feed of the film, the magnetic head 35 is driven by the magnetic recording / reproducing circuit 27, and data is recorded outside the photographing screen at the photographing frame position. The information recorded here includes exposure data, shooting date and time data, and frame number data in addition to the designated data. The frame number data is stored in the RAM 2
9 corresponds to the frame number count data updated for each photographing.

When the data recording on the magnetic recording layer is completed by the magnetic recording / reproducing device 27 and the feeding of one frame of the film is completed, the digital camera controller 22 inputs an image data recording command to the image data processing circuit 44. I do. As a result, the image data for one screen stored in the buffer memory 46 is transferred to the built-in memory 48 via the I / O port 47 and written there.

In the process of recording image data, the photographic camera controller 20 is connected to the digital camera controller 2.
2 reads out the additional information, the ID code, and the frame number data which have been written in the RAM 29 in response to the request from the controller 2, and transfers them to the digital camera controller 22. The combination of the ID code and the frame number is used as an identification code of image data for one screen, and is written in the built-in memory 48 together with the image data.

FIG. 5 shows a memory map of the internal memory 48.
In the area starting from the address "A000", header information of the built-in memory 48, that is, identification code, additional information, a starting address of a writing area of image data described later, data indicating a memory capacity of each area, and the like are written. Have been. Then, the identification code determined by the photographing of the first frame is written in the identification code area starting with the start address “B000”, and the image data of the first frame is written in the first image data area starting with the start address “D000”. Written.

The built-in memory 48 is further provided with an additional information area starting with the head address "C000", in which the magnetic head 35 is mounted with the photographic film 8a.
The same data as the designated data or the like recorded on the magnetic recording layer is written. The number of bits of data to be written in each of the identification code area and the additional information area is determined to be a fixed number of bits per frame, and the memory capacity is determined so that 50 frames of data can be written. Similarly, the memory capacity of the image data area is constant for each screen.

By repeating the above-described photographing and image data writing processing, the photographic film 8a becomes one.
The frame is digested frame by frame, and the identification code, additional information, and image data are sequentially written into the built-in memory 48.
Then, the photographing is performed at the last frame position of the photo film 8a, and when the image data is written into the built-in memory 48 together with the identification code and the additional information, the processing for one photo film is completed.

The photographic camera controller 20 gives a film rewind command to the film feeding mechanism 26, whereby the exposed photographic film 8a is rewound to the cartridge 8b. When the rewinding is completed, the cartridge 8b
The film entrance is closed by a light-shielding lid, and the opening / closing lid 9 is opened so that the photographic film cartridge 8 can be taken out. The photographic film cartridge 8 is subjected to a developing process. The built-in memory 48 stores image data and additional information for the same number of frames as the number of frames photographed on the photographic film 8a.

The photographic film 8a having undergone the development processing is
It is stored again in the same cartridge 8b and returned to the user. When the user wants to change the designated data (including the default setting) set at the time of photographing, for example, the print size, the photographic film cartridge 8 containing the developed photographic film 8a is loaded into the cartridge chamber of the still camera 1. To load. Immediately thereafter, it is detected that the photo film cartridge 8 has been used, and a warning to that effect is displayed on the liquid crystal display monitor 12. When the reproduction key of the key input unit 14 is operated, the digital camera controller 22 And the ID code of the loaded photo film cartridge 8 and the I code stored in the built-in memory 48.
Check with D code.

If the ID code of the photographic film cartridge 8 does not match the ID code stored in the built-in memory 48, the digital camera controller 22
Displays a warning on the liquid crystal display monitor 12. If they match, the image data is sequentially read out from the built-in memory 48 one frame at a time to read the image data.
2 is displayed. At this time, the frame number data and additional information of each photographed frame are also read out from the built-in memory 48 and displayed on the liquid crystal display monitor 12 so as to be superimposed on the display image.

When the desired image is displayed, the reproduction key is operated again to stop the frame advance. If this display image is designated as the conventional size, for example, as shown in FIG.
1 is displayed. Next, when the additional information setting key of the key input unit 14 is pressed, in addition to the specified data 56 specified by the user at the time of photographing (including the default data),
Exposure data 64 and shooting date data 65 automatically recorded at the time of shooting are displayed.

As in the case of photographing, since the item of the designated data 56 in which the arrow-shaped cursor 57 is displayed is in a changeable state, the cursor-moving keys of the key input unit 14 are operated to move the designated designated data to the desired designated data. Move the cursor 57. Since the exposure data 64 and the shooting date data 65 cannot be changed, the arrow cursor 57 does not move to each item of the exposure data 64 and the shooting date data 65 even if the cursor movement key is operated.

To change the print size,
When the arrow key 57 is moved to "print size" and the enter key is pressed, the characters "H", "C", and "P" are arranged side by side in the "print size", and other additions are made. The information is hidden (B). When the cursor cursor is operated to move the arrow-shaped cursor 58 to a desired “P”, the P mask 62 is displayed instead of the C mask 61 (C). Thereafter, when the enter key of the key input unit 14 is pressed, the designation mask 56, the exposure data 64, and the shooting date data 6 are displayed as shown in FIG.
5 is displayed.

Next, the arrow cursor 57 is set to <end of setting>.
When the enter key of the key input unit 14 is pressed according to 56a,
The newly specified data 56 is overwritten in the additional information area of the built-in memory 48. After this, still camera 1
Is driven out of the cartridge 8b, and the corresponding photographic frame (the photographic frame whose frame number 55 is 19 in this embodiment) is conveyed to the aperture position at a high speed. While one frame is fed toward a shooting frame (frame number 55 is a shooting frame of 18), the magnetic recording / reproducing circuit 27 uses the magnetic head 35.
Is driven, and the changed additional information is overwritten on the magnetic recording layer of the photographic film 8a.

The liquid crystal display monitor 12 displays the photographic film 8
Irrespective of the conveyance of a, as shown in FIG. 8, the captured image and the designated data 56, the exposure data 64, and the photographing date data 65 are displayed as they are, so that the designated data 56 can be changed again. When the reproduction key of the key input unit 14 is pressed again from this state, the frame number 55 changes, and at the same time, the image data corresponding to the frame number 55 is called from the built-in memory 48, and the captured image is displayed on the liquid crystal display monitor 1.
2, the designated data 56 of each captured image can be changed in the same manner as described above.

In the embodiment described above, the specified data of the additional information is rewritten by loading the developed photo film cartridge, but before the photo film cartridge is taken out of the still camera after the photographing is completed, the image data is stored in the built-in memory. The additional information may be read and the designated data may be rewritten. Further, all the additional information written to the magnetic recording layer at the time of photographing is written in the built-in memory, but a part of the additional information, for example, only the designated data may be used.
Also, a removable memory card may be used instead of or in combination with the built-in memory. In this case, the memory capacity can be easily expanded, and if a plurality of memory cards are used for replacement, image data and additional information can be stored and managed indefinitely. Further, in the above embodiment, the memory capacity of the built-in memory is one photo film, but it is needless to say that the memory capacity may be two or more.

Although the above embodiment is directed to an IX-240 type photographic film cartridge, the present invention is not limited to this photographic film cartridge, and a unique ID code is attached to the photographic film cartridge. In addition, any photographic film cartridge having a function of storing a developed photographic film in a roll form can be applied in exactly the same manner. In addition, the mask is translucent gray, but the present invention is not limited to this, and may be, for example, a black halftone dot.

As a further developed form, it is also effective to incorporate a memory in the photo film cartridge 8 and write the image data, additional information and identification code written in the built-in memory 48 into this memory. In this case, the photographic film cartridge 8 containing the developed photographic film becomes a memory for storing low-quality image data for index image reproduction, and at the same time holds high-quality image information photographed on the photographic film. Memory. Therefore, the correspondence between the index image and the high-quality photographic image is complete, and the operability when performing post-processing can be made very simple. Also,
In this case, since the photo film, the image data, and the additional information are integrated, the ID code can be omitted.

As described above, the still camera of the present invention writes image data and additional information taken at the same time as taking a picture in a memory, reads out the image data and the additional information from the memory after the shooting, and writes the read data on a liquid crystal display monitor. Since the additional information is set again while being displayed, and the additional information written on the magnetic recording layer of the photographic film is rewritten, it is easy to specify the additional information again even after the image is taken. As a result, there is no need to set additional information forcibly at the time of photographing, so that there is no risk of missing a photo opportunity in snap photographing or the like that requires quickness.

Further, the image data and additional information taken at the same time as the photographing are written in the memory of the photo film cartridge, and after the photographing, the image data and the additional information are read out from the memory, and the additional information is set while being displayed on the liquid crystal display monitor. Since the additional information written on the magnetic recording layer of the photo film is rewritten, the correspondence between the recorded image data and the additional information and the photo film is reliably maintained, so that another photo film cartridge can be used. Even after shooting or after a long period of time, additional information can be changed easily and reliably.
