[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a system according to the present embodiment. A photographic lens for forming a subject image includes a positive lens 1 and a negative lens 3, and an aperture mechanism 2 is disposed in the photographic lens. The aperture mechanism 2 is driven and controlled by an aperture drive circuit 12. I have. A half mirror 4 is provided behind the negative lens 3, and a part of the subject light reflected by the half mirror 4 forms an image on an area sensor 15 through an imaging lens system 14.

The area sensor 15 is controlled by the area sensor drive circuit 13, converts the formed subject image into an analog video signal, and outputs the analog video signal to the signal processing circuit 22. The signal processing circuit 22 performs predetermined signal processing including conversion of the analog processing signal into a digital signal. The signal processing circuit 22 includes a video memory 21 and a liquid crystal monitor (hereinafter, referred to as a liquid crystal monitor)
LCD monitor 23, and a non-volatile memory 26 via a data bus 24. The signal processing circuit 22 transfers the processed signal to the video memory 21 and the nonvolatile memory 26, and the electronic image stored in the video memory 21 is displayed on the LCD monitor 23.

The non-volatile memory 26 retains an electronic image even when the power of the camera body is turned off, and is therefore convenient as an electronic image recording medium. Further, when the nonvolatile memory 26 is configured to be freely attachable to the camera body,
When the storage capacity of the memory is exceeded, it is easy to replace the memory. Note that using a volatile memory instead of the nonvolatile memory 26 as a storage medium
This is possible by providing a backup power supply,
By using a non-volatile memory, the subject image can be stored even when the power of the camera is turned off, which is convenient. If an electrically rewritable memory is used as the non-volatile memory, additional rewriting can be performed when the storage capacity is exceeded, which is convenient.

Further, the brightness of the subject is measured using an analog signal of the area sensor 15. For the photometry, the analog signal is digitized by the signal processing circuit 22 and then transmitted to the CPU 27 via the data bus 24. Further, a movable mirror 5 having a half mirror at a substantially central portion is provided behind the half mirror 4, and a sub-mirror 32 is provided on a central rear portion of the movable mirror 5 so as to reflect object light downward. It is provided in.

On the optical path reflected by the sub-mirror 32, a separator optical system 16 composed of two lenses for separating two images is arranged in a direction perpendicular to the drawing. A line sensor 17 is disposed at a position where the subject image is formed by the separator optical system 16, and the line sensor 17 is connected to a line sensor drive circuit 19. These sub-mirror 32, separator optical system 16, line sensor 17
Thus, a focus detection device based on a known phase difference method is configured, and the CPU 27 obtains an interval between two images based on a signal input via the line sensor drive circuit 19, and drives the focus to a focus position. The driving amounts of the photographing lenses 1 and 3 are calculated.

Each of the lenses 1 and 3 of the photographing lens is provided with a zoom / focus drive circuit 11 for controlling a drive source for a focus adjustment operation and a zooming operation. The zoom / focus drive circuit 11 has an encoder (not shown) that generates a signal in accordance with the movement of each lens. The CPU 27 adjusts the focus based on the calculated drive amount and the encoder output. I do. On the reflected light path of the movable mirror 5, a focusing plate 29, a pentaprism 30, and a finder eyepiece optical system 31 are arranged. The reason for providing the above-mentioned optical finder in addition to the LCD monitor 23 for monitoring the subject is that the camera operator takes a picture rather than taking a picture while looking at the LCD monitor 23.
This is because taking a picture while looking through the optical viewfinder improves the holding performance of the camera and makes camera shake less likely.

The above-mentioned movable mirror 5 is a mirror driving circuit 18
, And the shutter 6 is driven by a shutter drive circuit 20. At the time of observation for determining the composition, the movable mirror 5 is lowered, and when the release button 38 (see FIG. 4) for instructing exposure start is pressed in two steps, the movable mirror 5 is raised and the shutter 6 is opened. In this state, a subject image is formed on the silver halide film 7 and is exposed. The CPU 27 calculates the aperture value and the shutter speed of the aperture 2 for obtaining the proper exposure based on the subject luminance value output from the signal processing circuit 22 and the film sensitivity detected by a film sensitivity detection circuit (not shown). Shutter 6
Is driven at the calculated shutter speed.

A magnetic recording layer is formed on the silver halide film 7, and a magnetic head 8 is arranged so as to be in contact with the magnetic recording layer. The magnetic head 8 has a function of magnetically recording various information and a function of reading information magnetically recorded on a film, and the magnetic head drive circuit 9 controls writing and reading. A film drive circuit 10 is provided in the camera body.

The focus drive circuit 11 is connected by a data bus 24 and exchanges data. The operations of these drive circuits and the like are controlled by the CPU 27 as a whole.

Next, the operation of the camera when loading a film will be described with reference to the flowchart shown in FIG. First, when a film cartridge is loaded in the camera of the present invention, a film loading subroutine is called from a main routine (not shown), and it is determined whether or not a film cartridge storage lid (not shown) is closed (step S1). If it is determined that the cartridge is present, in step S2, a barcode provided on the cartridge is read. The barcode indicates the ISO sensitivity of the film and the exposure state of the film. The exposure state means that the film is completely unexposed, all frames have been exposed, only some of all the frames have been exposed, and after the development process has been performed in the developing station, and in that order, unexposed, exposed Called, partially exposed, and developed.

Next, in step S3, the feeding of the film is started, and the control according to the exposure state of the film is performed.
In step S4, it is determined whether the image has been developed or exposed. If the image has been developed or exposed, step S5
Then, the identification code of the film magnetically recorded in the film reader unit (not shown) is read, the first frame is searched (step S6), and the feeding is stopped (step S1).
0), and returns to the main routine (not shown) (step S1)
5). The film is not photographed because the exposed state is developed or exposed. Therefore, after reading the identification code of the film as described above, the feeding may be stopped or the film may be rewound.

The above identification code is a code for identifying the film cartridge loaded in the camera on the camera side, and is magnetically recorded in a film reader (not shown) when the film cartridge is first loaded in the camera. . This identification code is formed based on, for example, camera ID data and date, and is recorded as a code unique to the cartridge. In addition, when an identification code is assigned to each cartridge in advance by a film manufacturer, for example, when a bar code is displayed on the side of the cartridge, or when a serial number is recorded on a magnetic recording portion of the film for each individual cartridge. If so, this can be used.

If it has not been developed or exposed in step S4, it is determined in step S7 whether or not partial exposure has been completed.
If the partial exposure has been completed, in step S8, the identification code of the film magnetically recorded in the film reader unit (not shown) is read, and the head is searched for unexposed frames (step S9), and the process branches to step S10. Stop film feeding. As described above, in steps S5 and S8, since the identification code can be read when the film is loaded, the corresponding image can be displayed immediately.

Next, if it is determined in step S7 that partial exposure has not been completed, it is determined in step S11 whether or not partial exposure has been performed.
A film identification code is magnetically recorded on a film reader (not shown), and the first frame is searched (step S1).
3), branch to step S10. In step S11,
If it is not unexposed, it does not belong to any exposure state,
It is determined that there is an abnormality, and a predetermined abnormality process is performed in step S14.

When it is determined in step S11 that the film is not exposed, only the identification code is recorded, and the identification code is not read out. Is not stored in the non-volatile memory 26, so that unnecessary operations are omitted.

Next, the photographing sequence in this embodiment will be described with reference to FIG. This shooting sequence is executed in response to the release switch being turned on by operating the exposure start instruction operation member 38. First, silver halide photography and electronic imaging are performed in parallel (step S61,
S62). Here, in the silver halide photography, after the diaphragm 2 is stopped down, the shutter 6 is opened, thereby exposing the silver halide film 7 to the subject image. In the electronic imaging, the image signal from the area sensor 15 is read in parallel with the exposure of the subject image on the silver halide film 7. Next, in step S63, processing such as compression of the electronic image data is performed.

Subsequently, a head address for storing the electronic image data in the nonvolatile memory 26 is set from the identification code of the film cartridge and the photographing frame number of the silver halide film (step S64), and the set address is set. The electronic image data is stored based on the address (step S6).
5). Therefore, in order to load an exposed film cartridge into the camera and display an electronic image corresponding to a specific frame on the LCD monitor 23, a nonvolatile memory is used based on the identification code of the film cartridge and the number of the frame to be displayed. What is necessary is just to search 26 addresses.

The push buttons 42, 43, and 44 and the electronic dial 41 are operation members for selecting a screen or setting information according to the present invention.

FIG. 5 shows a display example on the LCD panel 40 when a developed film is loaded in the camera. The operation method of the operation member of FIG. 4 will be described together. When the developed or exposed film is loaded in the camera, the identification code of the film is read out as described with reference to FIG. 2, and the electronic image corresponding to the identification code and the information set in the past are stored in the nonvolatile memory 26. The electronic image corresponding to the first frame of the film and information set in the past are displayed. If there is no information set in the past, a predetermined initial value is displayed. At this time, when the electronic dial 41 is operated, an electronic image corresponding to an arbitrary frame is selectively displayed.

FIG. 5A is an electronic image corresponding to the first frame of the film, FIG. 5B shows information that can be set by the operator, and FIG. 5A is superimposed on FIG. 5A, and the electronic image displayed on the LCD panel 40 is as shown in FIG. 5C. "FLAME N" in the figure
"O" indicates the number of frames, 100 indicates the number of additional prints, "TITLE" indicates the title of the photographed frame, "LANGUAGE" indicates the language of the title, "COLOR" indicates the color correction information, and are items that can be set by the operator. DATE ”
This is a shooting date and time corresponding to the shooting frame. In the example of FIG.
It shows that the number of frames is 1, the number of additional prints is 0, there is no title, there is no language, there is no color correction, and the shooting date and time is November 1, 1996.

As described above, the subject image and the data to be recorded corresponding to the subject image are simultaneously displayed on the LCD panel 40, and the photographer can check the subject image and the recorded data at the same time, which is convenient.

Next, the procedure for setting the information will be described. A button 42 is an operation button for turning on / off the data input mode. When the operation button is operated to set the data input mode, the number of shot frames, the number of additional prints, the title of the shot frame,
It is possible to select one of the setting items of the language / color correction information and to select the content of each of the setting items. After setting the data input mode, when the button 43 is pressed, the setting items are scrolled in sequence each time the button 43 is pressed,
The operator selects a desired setting item.

When the electronic dial 41 is rotated after the setting item is selected, the setting content of the setting item can be selected. For example, the number of reprints is
"0", "1", "2", "3", "5", titles are none, "congratulations", "entrance ceremony", "wedding",
Languages are none, "Japanese", "English", "German",
Color correction may be none, "red", "green", "blue", or the like. Note that the color correction designates which color of red, green, and blue should be emphasized for the print finish. When the information setting is completed and the setting end button 44 is pressed, the information set for each frame is magnetically recorded on each corresponding frame, the film is rewound, and the data input mode is released. The set information is also stored in the nonvolatile memory 26.

When the film on which the above information is magnetically recorded is sent to a developing laboratory, color correction set for each frame and printing of a title in the set language are performed, and printing is performed for the number of additional prints. In the above description, the case where a developed or exposed film is loaded is described.However, when a partially exposed film is loaded, only the electronic image corresponding to the exposed frame is displayed and information is set. When an unexposed film is loaded, information setting is prohibited because there is no electronic image corresponding to the film.

FIG. 6 is a flowchart for explaining the processing of the operation system. A switch processing subroutine is called from a main routine (not shown).
It is determined whether the identification code read in step S5 is stored in the nonvolatile memory 26 (step S2).
1). If the read identification code is stored, the corresponding electronic image is also stored, so the flow advances to step S23 to call a subroutine for image reading. If the identification code is not stored, the process proceeds to step S23. Proceed to S43. In this case, the fact that no image is stored may be displayed on the LCD monitor 40 before proceeding to step S43.

Next, an image reading subroutine S23
First, as shown in FIG. 7, based on the read identification code, an area where an electronic image corresponding to the film currently loaded in the camera is stored is searched from the nonvolatile memory 26, and the area is searched. Specify (Step S
51). Next, the address corresponding to the first frame is searched in the searched area (step S53), and the electronic image stored at this address and the information set in relation to this electronic image are read. (Step S55), the read electronic image and information are displayed on the LCD monitor 23 (Step S57), and the process returns to the routine shown in FIG. 6 (Step S59).

In this flow, since the first frame is located at the beginning (step S6 in FIG. 2), the electronic image corresponding to the first frame is automatically read out first. Of course, an electronic image or the like corresponding to the frame designated by is read out. Also, as shown in this flow, the electronic image of the first frame is not automatically read out, and the electronic dial 4
After arbitrarily specifying a film frame in step 1, the electronic image of the specified frame may be read. Further, the display is not limited to the display for each frame, but all or a plurality of frames of the film cartridge corresponding to the identification code may be displayed in a list, and the electronic dial 41 may be selected from the list.

Returning to the flow shown in FIG. 6, step S2
At 5, the states of the operation buttons 42, 43, 44, the electronic dial 41, and other switches (not shown) are read. Next, it is determined whether or not the operation button 42 has been pressed (step S27). When it is determined that the operation button 42 has been pressed, the mode is set to the data input mode (step S29). It becomes possible to select. When the operation button 42 is pressed again in the data input mode, the data input mode is released.

Next, it is determined whether or not the operation button 43 has been pressed (step S31). If it is determined that the operation button 43 has been pressed, setting items such as the number of additional prints and the title of the photographed frame are switched (step S33). Next, it is determined whether the electronic dial 41 has rotated (step S35). If it is determined that the electronic dial 41 has rotated, the setting contents are scrolled according to the amount of rotation. In
This number changes (step S37). Next, it is determined whether or not the operation button 44 has been pressed (step S39). If it is determined that the operation button 44 has been pressed, setting end processing such as magnetic recording and film rewinding of the set information to the corresponding frame is executed (step S39). S41). Other switch processes are performed in step S43, and the process returns in step S45.
