However, a normal camera for photography cannot take a number of shots exceeding the number of frames of the photographic film. When shooting the number of frames of the film for shooting, it is necessary to replace the film for the next shooting. Therefore, hesitate to shoot while worrying about the number of remaining frames,
You may miss important photo opportunities, such as taking time to exchange films. On the other hand, in a normal electronic camera, since the photographed result is electronically recorded image data, the image cannot be used or stored as a developed film (negative or positive). In addition, it is not possible to take a picture a number of times exceeding the capacity of a memory medium such as smart media, and if the image data is deleted without being backed up, the opportunity to reproduce the taken image is permanently lost. Also, if it is a negative film, you can bring it to a print service store and make 50 or more copy prints in 1 minute, and the print unit price is about 10 yen / sheet, but you can bring in a memory medium and use image data with an inkjet printer. When asked to print, it takes 1 minute to print one sheet, and the print unit price exceeds 100 yen.

On the other hand, in the cameras disclosed in Japanese Patent Laid-Open Nos. 61-215538 and 61-73116, the photographic film is exposed at the same time when the electronic image is taken, so that the number of frames of the photographic film is increased. Because the number of shots is limited, unnecessary shots and unsuccessful shots remain on the developed film. Further, the cameras disclosed in Japanese Patent Application Laid-Open Nos. 10-93849 and 11-127409 cannot make additional printing using general printing paper. It is an object of the present invention to provide an electronic camera that can easily use existing services such as mass copying and free enlargement by utilizing existing developing and printing service shops and print factories in any town. .

SUMMARY OF THE INVENTION An electronic camera with a printer according to the present invention includes a photographic optical system which allows light from a photographic subject to enter and forms an image on a predetermined image forming plane, and an image forming plane of the photographic optical system. In an electronic camera having an image sensor arranged and a storage means for accumulating image data of a plurality of shots captured using the image sensor, a cartridge is held so that it can be taken in and out, and an unexposed film for photography is pulled out to form a latent image. After formation, the film mechanism is stored again in the original cartridge, latent image printer means for exposing and forming a latent image corresponding to image data on the photographic film by determining the light emission amount for each pixel, and a plurality of shots accumulated in the storage means A control circuit for supplying the latent image printer means with image data manually or automatically selected from the above image data to form a latent image on the unexposed photographic film. A.

[0006]

In the electronic camera with a printer of the present invention, only the necessary image data selected from the image data stored in the storage means is recorded as a latent image on the photographic film by using the latent image printer. The photographic film on which the latent image has been recorded is brought to an existing photofinishing service store as in the case of directly photographing on the photographic film, and processed into a film such as a negative or positive film and a photographic paper print.

1 is an explanatory view of an electronic camera with a printer according to a first embodiment, FIG. 2 is an explanatory view of a latent image printer, FIG. 3 is an explanatory view of a light source, and FIG. 4 is supplied to the latent image printer. FIG. 6 is an explanatory diagram of image data according to the present invention. As shown in FIGS. 1 and 2, the electronic camera with a printer 10 according to the first embodiment converts a captured image captured by the solid-state image sensor 12 into image data and converts the captured image into a memory medium, as in a normal electronic camera. Accumulate at 15. Then, using the image data selected from the memory medium 15, the latent image of the photographed image is recorded for each frame of the photographing film 35. The latent image is recorded by the R generated by the light source 25.
The scanning of the scanning line 34 is performed by scanning the GB light with the polygon mirror 31, and the film 35 for photographing is sent to arrange the scanning lines 34 to expose the frame surface.

The photographing optical system 11 includes a plurality of lenses, an aperture and a shutter arranged in the pupil of the lens group,
A projected image of the subject is formed on the image pickup surface of the image pickup device (CCD) 12. The A / D converter 13 samples the analog voltage signal output from the image sensor 12 and converts it into digital data. The CPU 14 forms image data of a captured image based on the digital data input from the A / D converter 13 and stores the image data in the memory medium 15. The memory medium 15 is a flash memory device called “smart media”. Memory medium 15
Is detachably inserted into the main body of the electronic camera 10 with a printer, and is detached while holding the image data of the captured image,
It is possible to transfer image data by connecting to an external computer alone. The liquid crystal monitor 16 reproduces the image signal input from the CPU 14. At the time of shooting, the images captured by the solid-state image sensor 12 are displayed on the LCD monitor 16 every moment.
When a moving image is displayed in and the shutter operation is performed, the captured still image is displayed in place of the moving image for a few seconds.

The I / O circuit 21 stabilizes the operation signals of various switches and inputs them to the CPU 14. The mode switch 17 turns on the power of the electronic camera 10 with a printer.
Used to set / OFF and use mode. There are three setting contents: a shooting mode for newly electronically shooting a subject, a printing mode for recording a latent image of image data stored in the memory medium 15 on the shooting film 35, and a power-off. The confirmation switch 18 in the photographing mode is used for shutter operation input. The confirmation switch 18 in the print mode is used for an operation input for starting latent image recording. The selection switches 19 and 20 are used for switching the image displayed on the liquid crystal display 16 (scrolling the image data).

The two sets of pinch rollers 28 are used for the cartridge 3
The photographic film 35 pulled out from 0 is sandwiched before and after the exposure position of the scanning line 34 and rotated at a constant speed to give a constant feed speed to the photographic film 35. The cartridge 30 is housed in the main body of the electronic camera with a printer 10 so that it can be taken in and out. Like a normal film camera,
When the cartridge 30 is stored in the electronic camera 10 with a printer, the leading end of the photographic film 35 is pulled out by a motor mechanism (not shown) and is wound around the take-up reel 29 through the space between the pinch rollers 28. When the unexposed frames of the photographic film 35 are exhausted, the feeding is reversed to collect the photographic film 35 wound on the take-up reel 29 into the cartridge 30 again. The take-up reel 29 winds up the photographic film 35 that has been pulled out from the cartridge 30 and exposed by the scanning line.

The control circuit 27 receives the print command and the image data from the CPU 14, and feeds the photographing film 35, rotates the polygon mirror 31, and rotates the light source 25.
Is controlled to print out the latent image of the photographed image on the unexposed frame of the photographing film 35. The control circuit 27 rotates the polygon mirror 31 at a constant rotation speed and sets the rotation speed of the polygon mirror 31 to 1 per second.
Shooting film 35 at a constant rate of per second multiplied by 50 μm
Is sent to the take-up reel 29 to be taken up. Also, C
An analog voltage signal is formed from the RGB density data of the pixel row for each scanning line of the image data sent from the PU 14, and the analog voltage signal is supplied to the light source 25.

The light source 25 uses the RGB analog voltage signals to cause the RGB light emitting diodes to emit light to generate independent RGB radiation beams. The collimator lens 26 converts the RGB radiation beam light emitted from the light source 25 into parallel light. The polygon mirror 31 scans the parallel light emitted from the collimator lens 26 to form a scanning line 34 having a length corresponding to the frame width of the photographic film 35. The f-theta lens 32 converges the parallel light scanned by the polygon mirror 31 onto the scanning line 34 to form a scanning (exposure) spot. The mirror 33 bends the scanning beam emitted from the f-theta lens 32 in a direction at right angles and makes it enter the photosensitive surface of the photographing film 35. The control circuit 27 starts supplying an analog signal to the light source 25 at the phase position of the polygon mirror 31 where the scanning spot falls on one end of the scanning line 34.

The read head 38 is formed by arranging a plurality of reflected light sensors. The I / O circuit 39 creates code data from the outputs of the plurality of reflected light sensors to generate CP data.
Input to U14. In the reading head 38, the reflected light sensor discriminates the contact pattern (mirror pattern) formed on the side surface of the cartridge 30 bit by bit, and the CPU 14 generates code data for specifying the type of the photographic film 35.
To read. The CPU 14 corrects the image data for printing by specifying the sensitivity of the photographic film 35 based on the read code data. Thereby, the light source 25
The variation range of the analog voltage signal supplied to the film is adapted to the film sensitivity, and the light emission level of the light source 25 is set lower in the high sensitivity film than in the low sensitivity film. In addition, the CPU 14
Identifies the number of printable frames based on the read code data, and when the number of prints matches the number of frames, instructs the Patrone 30 to start collecting the photographic film 35. Further, the negative / positive characteristics of the film are identified based on the read code data, and in the case of a positive film, the RGB density gradation in the image data for printing is reversed.

As shown in FIG. 3, the light source 25 includes a substrate 41.
The RGB integrated light emitting diode 43 is mounted on the.
In the light emitting diode 43, RGB light emitting diode chips 44 are wired on a ceramic base and molded with a transparent resin. A light-shielding film 42 is formed on the surface of the transparent resin mold.
Are formed on the light-shielding film 42 so as to correspond to the RGB light-emitting diode chips 44, and three rectangular openings 45 each having a side of 25 μm are formed. Each of the three square openings is R
It becomes an emission spot of GB and is projected one-to-one onto the photosensitive surface of the photographic film.

Of the R, G, and B radiation beams emitted from the rectangular aperture 45, the light incident on the collimator lens 26 is scanned by the polygon mirror 31 as parallel light, and is further incident on the f-theta lens 32, and on the scanning line 34. Independent exposure spots 46 of RGB are formed at. Since the focal lengths of the collimator lens 26 and the f-theta lens 32 are set equal to each other to form a one-to-one projection optical system, the size of the exposure spot 46 is equal to the size of the rectangular aperture 45, and R
The spacing of the GB exposure spots 46 is equal to the spacing of the square openings 45.

As shown in FIG. 4, the CPU 14 shifts the RGB pixel position of the image data selected by referring to the liquid crystal monitor 16 in the opposite direction by the distance corresponding to the RGB exposure spot 46. Create the data,
It is supplied to the control circuit 27. Specifically, the space between the square openings 45 is 600 μm, and the size of the square openings 45 is 25 μm.
The G (B) bitmap value is shifted by 24 pixels multiplied by m in the positive (negative) direction of the scanning line. As a result, the RGB exposure spots 46 of the same pixel are overlapped on the scanning line 34, and the RGB pixel shift when performing scanning exposure with the three independent RGB exposure spots 46 is offset.

The printer-equipped electronic camera 10 of the first embodiment.
Then, when the mode switch 17 is set to shooting, a moving image of a subject condition that can be shot can be displayed on the liquid crystal monitor 16 to wait for a photo opportunity. When the confirmation switch 18 is pressed in this state, the photographed image is converted into compressed image data, and reference information (photographing number or the like) is attached to the memory medium 15.
Recorded in. On the other hand, when the mode switch 17 is set to print, the CPU 14 calls the oldest image data stored in the memory medium 15 and reproduces the image on the liquid crystal monitor 16. When the selection switch 20 is pressed in this state, the next oldest image data is reproduced and the selection switch 1
When 9 is pressed, the image data of the latest image data is reproduced. The selection switch 20 corresponds to the feeding in the numerical order, and the selection switch 19 corresponds to the feeding in the reverse order.

In this way, by operating the selection switches 19 and 20 with reference to the liquid crystal monitor 16, the image data to be printed is selected. Then, the LCD monitor 16
Confirm switch 18 with the desired captured image being played back.
When is pressed, the CPU 14 instructs the control circuit 27 to start printing, converts the image data into print image data, and sends the print image data. The control circuit 27 performs scanning line exposure on the photographic film 35 with the print image data to record a photographic image as a latent image.

The printer-equipped electronic camera 10 of the first embodiment.
According to the method, the photographed image is converted into image data and the memory medium 15
Since the images are recorded in No. 2, the shooting shots can be overlapped without worrying about the number of frames of the shooting film 35, and there is no fear of missing a photo opportunity by worrying about the number of frames of the shooting film 35. Then, when the photographing is completed or when the photographing is completed, by referring to the liquid crystal monitor 16 and selecting the image data, only the necessary photographed image is taken.
Since the latent image is recorded on the recording film 35, it is not necessary to waste the photographing film 35 for unnecessary photographed images such as defocusing, improper exposure and poor composition. Then, the film for photographing 35 on which the carefully selected photographed image is recorded as a latent image can be rewound to the cartridge 30 and collected and processed in the existing photo processing facility through the developing and printing service shop located anywhere, so that it can be freely expanded /
Services such as reduced printing and mass printing are available at low cost.

Further, the latent image recording on the photographic film 35 is carried out at a film feed speed of 25 μm / scanning line using a scanning spot of 25 μm square, so the resolution of the latent image recording is about 1000 dpi vertically and horizontally. Even if it is doubled and reprinted, a fine reprinted print of 200 dpi or more can be obtained. Further, since the latent image is recorded on the photographing film 35, the length of the scanning line 34 is only 25 mm. Therefore, the polygon mirror 31 and the f-theta lens 32 are smaller than those for plain paper printer and instant film exposure. In addition, a lightweight, compact, and inexpensive latent image printer can be configured. Further, as shown in FIG. 3, since the length of the scanning line 34 is short, the collimator lens 26 and the light emission spot mask 42 are formed.
Is also shortened, and as a result, the “ratio of being incident on the collimator lens 26 and being converged on the scanning spot 46” in the total light emission amount of the light emitting diode 44 is high. Therefore,
It is possible to configure a high-speed and energy-saving latent image printer that rotates the polygon mirror 31 at high speed while reducing the current supply to the light emitting diode 44. Further, the read head 38 is provided to provide a contact point pattern (mirror pattern) of the cartridge 30.
Is read and reflected in the exposure conditions for latent image recording, the image quality after development is not impaired by the difference in sensitivity, and photographic films with various sensitivities can be used without troublesome setting for each sensitivity. Further, even if shooting is performed to the full capacity of the memory medium 15, if the printed image data is erased, it is possible to secure a free space and stack shooting shots. In other words, the number of times of shooting “capacity of memory medium 15 + number of film frames” which is larger than the number of film frames than the capacity of the memory medium 15 is possible. Further, since the image pickup device which is much smaller than the film frame area is used for image pickup, the image pickup optical system 11 having the same performance as that of a camera which directly exposes the film can be constructed in a small size, a light weight and a low cost. In addition, the volume (cavity) of the optical system occupied in the camera is reduced, and the degree of freedom in external design is increased.

The memory medium 15 may be a removable memory device other than the "smart medium" or a recording device such as a floppy (registered trademark) disk drive.
It may be a semiconductor element that is fixed on the circuit board and cannot be taken out, or a RAM element that loses data when the power is turned off. Further, the latent image printer system may be a scanning system other than a polygon mirror, or may be a combination of a linear dot device such as an LED dot array, a liquid crystal dot array + light source, an organic EL dot array and a film feeding mechanism.
Further, it may be in a form of contact exposure or projection exposure of a photographed image displayed on an image device such as a liquid crystal projector or a CRT. Further, in the first embodiment, the photographer selects a print image by referring to the liquid crystal monitor 16, but the CPU 14
Alternatively, the automatic selection may be performed by automatically identifying image data with out-of-focus or poor exposure and removing it from print candidates. In addition, the contact pattern of the cartridge may be identified by the presence or absence of electrical conduction between the brush contact and the brush metal, and instead of the contact pattern, it is provided adjacent to the contact pattern. You may read the barcode. Instead of the cartridge, a magnetic recording pattern or a punch hole pattern formed on the photographic film itself may be read. Alternatively, the mode switch 17, the selection switches 19 and 20, and other input switches (not shown) may be displayed on a liquid crystal monitor with a touch panel as an image, and switch input may be performed by touching the screen.

FIG. 5 is a rear view of the printer-equipped electronic camera of the second embodiment. On the front side of the printer-equipped electronic camera 50 of the second embodiment, the same photographing optical system, image sensor and mode switch as those of the first embodiment are arranged. Then, as in the first embodiment, an electronic circuit including a memory medium for accumulating image data of a plurality of shots, a CPU, and a latent image printer are arranged inside. Then, the film cartridge of the photographic film is held in the inner space of the lid 66 on the back surface so that it can be taken in and out.

A 3-inch type liquid crystal monitor 51 is arranged above the rear surface of the electronic camera 50 with a printer. Similar to the first embodiment, the liquid crystal monitor 51 fully displays one moving image and one still image during shooting, and also one entire selected captured image during printing. In addition to this, a new reduced image 52 of 15 mm × 11 mm can be added up to 1 here.
A list of up to 6 can be displayed. By operating the selection switches 53 and 54, the cursor displayed on the reduced image 52 of the liquid crystal monitor 51 can be moved forward and backward.
If the selection switch 53 is pressed with the cursor at the position 001, the page moves to the previous page (the last page if there is no previous page), and if the selection switch 54 is pressed with the cursor at the position 016, the next page is displayed. 1 starting with 017
Six reduced images are displayed on the liquid crystal monitor 51.

The switch 55 displays all the image data accumulated in the memory medium as 16 reduced images. The switch 56 displays the entire reproduced image of the image data selected by the cursor on the liquid crystal monitor 51. Switch 57
Is the print selection for the image data at the cursor position,
The switch 59 is used to cancel the print selection for the image data at the cursor position. The switch 60 is used when analyzing the image data and automatically adjusting the correction of the image data for printing (operating condition of the latent image printer). The switches 61 and 62 are used when the exposure level of the print is adjusted with reference to the image displayed on the entire surface of the liquid crystal monitor 51. The switch 63 is for inputting the start of printing. The switch 64 is for inputting designation of negative / positive reversal exposure.

In the electronic camera with a printer of the second embodiment, when the switch 55 is pressed in the print mode, the liquid crystal monitor 5
In FIG. 1, 16 reduced images of the image data accumulated in the memory medium are displayed in order from the oldest, and the reduced image at the position 001 is displayed with the cursor overlaid. In this state,
Operate the selection switches 53 and 54 to move the cursor,
When the switch 57 is operated over the reduced image of the image data to be printed, the image data is registered in the print group. The reduced image of the registered image data is displayed dark as indicated by the diagonal lines. If in doubt, it is possible to operate the switch 56 and switch to full-screen display of one sheet for detailed examination. CP of electronic camera with printer
Similarly to the first embodiment, U recognizes the number of remaining frames of the photographic film, and continues to operate the selection switches 53, 54 and the switch 57 within the limit of the number of remaining frames to display a plurality of image data. Can be registered in a print group.

After that, when the switch 58 is operated, up to 16 reduced images of the image data registered in the print group are displayed on the liquid crystal monitor 51, and the reduced image at the position 001 is displayed with the cursor overlaid thereon. When the cursor is moved and the switch 59 is operated in this state, the image data at the cursor position is removed from the print group. If the switch 55 is operated in this state, a reduced image of unselected image data is also displayed. It is possible to add to the print group by placing the cursor on the reduced image for which designation has been forgotten and operating the switch 57.

In this way, when the switch 63 is operated with one or more image data registered in the print group, all the image data in the print group are printed out on the photographic film as they are. However, the print results can be corrected by operating the switches 60, 61, 62, 64 and 65. For example, when the switch 58 is operated to display the reduced image of the print group on the liquid crystal monitor 51 and the cursor is moved to select one image data and the switch 56 is operated, the image data is displayed on the liquid crystal monitor 51. Is displayed in full. When the switch 60 is operated in this state, the CPU of the electronic camera with printer is
Is an image that reads the maximum and minimum density values that actually exist in image data, shifts the maximum value to the maximum side, shifts the minimum value to the minimum side, and shifts the halftone to an intermediate state between them. Perform processing. The image processing result is displayed on the liquid crystal monitor 51, and if the user does not like it, the switch 60 can be operated again to restore the original state.

When one screen of the image data is displayed on the liquid crystal monitor 51 and the switch 61 is operated, image processing for giving a positive gamma characteristic to the image data is performed, the overall brightness level is increased, and the density level of the image is increased. Is reduced. Display the image data on the LCD monitor 51 one by one and switch 6
When 2 is operated, image processing for imparting a negative gamma characteristic to image data is performed, the overall luminance level is lowered, and the density level of the image is raised. When the image data is entirely displayed on the liquid crystal monitor 51 and the switch 64 is operated, the image processing of negative / positive inversion is performed on the image data. In this way, if the switch 63 is operated after performing the image processing on the required image data, the latent image is printed out based on the corrected image data.

According to the electronic camera with a printer of the second embodiment, a plurality of selected image data are collectively listed,
Since additional selection and selection cancellation can be performed, the image data to be latent image-recorded on the photographic film can be selected with sufficient consideration. For example, in the case of dividing the image data accumulated in the memory medium into a plurality of photographic films for latent image recording,
It is possible to distribute highly satisfactory image data to a plurality of photographic films without excess or deficiency. In addition, the image data accumulated in the memory medium can be image-processed to record a latent image, so a latent image of a high-quality photographed image in which defects during photography (errors in illumination and diaphragm, exposure failure due to backlight, etc.) are corrected You can record. Furthermore, since latent image recording can be performed using image data that has been negative-positive inverted, it is possible to create a slide film using a normal negative film or a negative film using a normal positive film.

[0030]

According to the present invention, since the photographed result is obtained as an undeveloped photographed film, the photographed result can be stored in the form of a negative film or a slide film. In addition, by using existing photofinishing service shops and existing print factories everywhere, it is possible to quickly and inexpensively use services such as mass copying and free enlargement. Further, since the photographed image is converted into image data and stored, the photographed shots can be overlapped without worrying about the number of frames of the photographing film. In addition, when shooting is completed or at the end of a stage, the image data to be recorded as a latent image on the shooting film is selected, so a high-value shooting film containing only the necessary shot images can be obtained, out of focus, improper exposure, It is not necessary to waste shooting film for unnecessary shot images such as poor composition.
