DESCRIPTION OF THE PREFERRED EMBODIMENTS As a feature of the present invention, this camera is provided with a "demo mode", abbreviated as "demo shooting mode", in addition to a first memory area strictly corresponding to the number of shot frames. A second memory area is separately provided for the demo shooting mode in which overwriting is optional after the demo shooting,
The device is devised so that it can be used properly as a storage means. Less than,
An embodiment will be described in detail for a camera capable of both digital photography and film photography according to the present invention.

FIG. 1 is a block diagram showing a configuration of a camera as one embodiment of the present invention. Control means 100
Is composed of a first control means 10 for mainly controlling the film photographing operation and a second control means 20 for mainly controlling the digital image photographing operation, together with a part for performing overall control of the entire camera. The first control means 10 and the second control means 20 are communicably connected to each other.

The first control means 10 includes a release SW 11 and a zoom SW 12 each including a dedicated operation member.
And a film photographing optical system 13 and a film photographing means 14 for exposing a silver halide film to a subject image for photographing.
And a switching means 15 for selectively switching a predetermined photographing mode or display mode, and a film presence / absence detecting means 16 for detecting the presence of a film cartridge.

The second control means 20 includes an image pickup optical system 23 and an image pickup means 24 for electronically picking up an image of a subject, an image display means 25 for displaying and outputting the picked-up image, and a storage means. First memory area 2 for storing an image corresponding to a scene shot on film
1 and a second memory area 22 for storing an image that does not correspond to a shooting scene on film.

The actual appearance of the camera of this embodiment is as shown in FIG. 2A when viewed obliquely from the rear, and has a display form as shown in FIG. 2B. In this camera, a memory card having the first memory area 21 and the second memory area 22 can be detachably used as external storage means. Also, in the screen of the image display means 25,
A display “24” corresponding to the number of frames as indicated by reference numeral 25a in FIG. 2A and a display “2001 316” as indicated by reference numeral 25b are output. On the other hand, as indicated by reference numeral 25c in FIG. 2B, a warning message "NO FILM" indicating that there is no film is output to the film presence / absence detecting means 1.
6 is set to be output based on the detection result.

The film presence / absence detecting means 16 detects whether or not there is a film in the patrone chamber.
It is made in a structure as shown in FIGS. That is, in order to read DX information formed on the surface of the loaded film cartridge 50, a plurality of DX detection sections 31 having a corrugated shape as shown in the drawing are arranged side by side on the peripheral wall surface in the cartridge room, and Is arranged so that conduction with the contact of the predetermined circuit 40 is established. Further, the mutual contact relationship changes due to the force f applied when the film cartridge 50 is loaded adjacent to the position orthogonal to the DX detection section 31, and for example, the cartridge detection unit arranged so as to cut off the conduction. The film section 32 is provided to constitute the film presence / absence detecting means 16.

That is, the structural features of the present invention include:
The storage unit is divided into two parts, a first memory area 21 for storing an image corresponding to film shooting, and an image not corresponding to a shooting scene on the film (that is, an image of a demo shooting).
And the second memory area 22 for storing the same. The operational control of the present invention is characterized in that images obtained in the film photographing mode and the electronic photographing mode are individually stored in the memory so as to correspond to the number of frames (frames) at the time of photographing in the display mode. An attempt is made to store and reproduce data under control for appropriately managing the area.

For this reason, the operation of the camera of this embodiment is controlled as follows. That is, the focal length of the film photographing optical system 13 is changed according to the operation of the zoom SW 12. Further, the presence / absence of a film in the camera is detected by the film presence / absence detection means 16, and when the release SW 11 is operated when there is a film, the film photography means 14 is controlled according to the presence / absence of the film to carry out photography. At this time, communication is made to the second control means 20 to communicate an imaging request for an image equivalent to a scene shot on film. In the second control means 20, the image information passed through the image pickup optical system 23 is picked up by the image pickup means 24 and stored in the first memory area 21 as an image.

If the release switch 11 is pressed when there is no film, the film is not exposed, but the same operation as when there is a film is performed. This is one shooting mode called "demo mode" for short. Such an operation has no meaning as a film shooting because no film is contained, but for example, an inspection test at the time of factory shipment, or when the user tried to purchase the camera, he operated this camera at the store of the camera store Since it performs the same operation as when there is a film at the time, the feeling of use can be confirmed, which is very effective.

Even in the case of the demonstration shooting without such a film, the communication to the second control means 20 is performed and the exposure to the film is not performed because there is no film.
The imaging request of the image at the timing when 1 is pressed is communicated. In the second control means 20, after the image information passing through the image pickup optical system 23 is picked up by the image pickup means 24, this image is
The image is stored in the memory area 22 as a “demo-compatible image”.
Since there are two storage areas for images as described above, an image captured in synchronization with film shooting and an image at the time of demonstration shooting are stored respectively. The captured image information is displayed and output by the image display means 25.

After photographing, photographing mode display mode switching means 1
When the display mode is set by the manual operation of No. 5, the image stored in the predetermined memory area of the storage means is displayed on the image display means 25 by the second control means 20. When the film presence / absence detecting means 16 detects that the film is in the patrone room, an image corresponding to the film in the first memory area 21 is displayed. This allows a user, a photographer, to check a scene shot on the film before developing the film.

For example, when the photographer operates the mode setting SW of the switching means 15 after photographing the 24th frame, 24
The image of the frame is displayed. Zoom S in display mode
W12 functions as a display image change SW, and a zoom-down SW (hereinafter, ZDSW) constituting the zoom SW 12
Abbreviation), the 23rd frame, the 22nd frame,
The image can be changed to an image corresponding to a film image having a small number of frames, such as the 21st frame. Also, zoom SW1
Similarly, the zoom-up SW (hereinafter abbreviated as ZUSW) constituting No. 2 can be changed to an image corresponding to a film image having a large number of frames such as the 23rd frame and the 24th frame.

As described above, the zoom SW 12 has both the meaning of up / down of zooming and the meaning of up / down of the number of frames of a display image. Both of them are up and down, so that operation is not lost. It is natural. Since the image corresponds to the film, it does not become smaller than the first frame even if it is downed by the ZDSW. Similarly, ZUSW
Even if they are sequentially up, they will not be larger than the largest frame shot. Further, by displaying only the image corresponding to the film, it is possible to prevent the user from seeing the displayed image and misunderstanding that the film was shot.

More specifically, a description will be given of a process of updating the number of frames corresponding to the demo mode and the film photographing mode and the memory area (number) in which images are stored. FIG. 4 shows the transition of the display mode of the demonstration shooting and the film shooting in this camera. In the demo mode without film (during demo shooting), when the user switches to the display mode by the shooting mode display mode switching means 15, an image previously shot in the demo mode is displayed. An image corresponding to the film frame used and two types of images corresponding to the demo shooting are stored in a predetermined memory area. The film has already been taken out, but the user sometimes wants to check the image of the taken out film, and such a camera is convenient because both images can be displayed. If desired, both images can be displayed by operating the zoom SW 12 as described above.

As shown on the left side of FIG. 4, when the images photographed in the demo mode are sequentially displayed at first, when the ZUSW is pressed, about 11 frames are photographed and stored in the film photographing corresponding to the film. The display target moves to the first frame, and by further pressing, the second frame, the third frame, ...,
And an image corresponding to a large number of frames can be displayed. It should be noted that, even if the image is raised by the ZUSW, it is not larger than the largest frame (the eleventh frame in this case).
Conversely, when the ZDSW is pressed, the number of frames gradually decreases,
The display target shifts from the frame corresponding to the film to the frame corresponding to the demo mode. In the demo mode, for example, if the user does not like the image corresponding to the memory area (number) 45 and wants to overwrite the same area, the ZDSW or ZU
After displaying the memory area 44 with SW, release SW
When imaging is performed by the operation of 11, the memory area is
(No.) 45 is overwritten with a new image.

As shown on the right side of FIG. 4, after photographing 11 frames of film, after photographing in the demo mode with the film removed, the photographing mode is switched to the display mode to electronically photograph in the demonstration mode. The images can be displayed as demo shooting frames sequentially by operating the ZDSW. Further, images as film shooting frames can be sequentially displayed by operating the ZUSW.

That is, in this camera, an image is written in a predetermined memory area of the storage means in accordance with photographing, and thereafter read and overwritten as necessary, and appropriate display control based on the display mode is performed as described above. I have. Therefore, in the image shooting and the image storage, it is possible to provide a convenient and effective function corresponding to a use mode in which only the image to be left is stored in the storage means while making full use of the display mode and the shooting mode.

The operation of the camera according to this embodiment will be described below with reference to FIGS. First, FIG. 5 shows the operation timing of this camera in a release sequence, and also shows the transition of photographing with a film and digital photographing with an electronic image sensor in a time-series manner. The first control means (hereinafter, silver halide CPU) 10 for controlling the silver halide film photographing is operated by half-pressing the first RSW (1st. Release SW) of the first stage constituting the release SW 11, and is further depressed to the second stage. When it is detected that the 2RSW (2nd. Release SW) of the eye is operated, the photographing using the silver halide film is executed, and the second control means (hereinafter, digital CPU) 20 for digital photographing control is executed. Communication is performed, and digital images are stored by electronic imaging.

More specifically, when the 1RSW is turned on at the timing shown in the release sequence, the silver halide CPU 10 as the first control means executes the photometry and then forms the digital CPU 20 as the second control means. Start the digital section. The reason for starting here is to save power.
That is, since the digital section digitally processes a very large amount of image data, the digital CPU 20 and related ICs and the imaging CCD and CMOS sensors need to operate at high speed, and thus consume a large amount of current. Similarly, the image display unit 25 using a liquid crystal or the like for the display unit also consumes a large amount of current when a backlight is required. Therefore, these units are basically put in a sleep state so as not to be operated except when necessary, to save power. Therefore, it is set so that a portion corresponding to only the above-described release operation or display output is activated.

When the fact that the 1RSW has been half-pressed is communicated, the digital section of the digital CPU 20 starts fetching one frame of image data following the initialization as shown in FIG. And ND filters to control exposure. At this time, if there is no strobe light, the exposure can be properly performed only on the digital side. However, if the strobe light is used, information such as the subject distance and the G No. of the strobe is required.
0 is stored in the digital CPU 2
0 to control the ND filter appropriately.

Further, when the 2RSW is pressed at the timing shown in the release sequence, the silver halide CPU 10 advances the photographing lens to focus on the subject, and performs communication for terminating the lens extension. This communication means that the shutter control preparation is OK. Next, the digital CPU 2 is used to adjust the flash emission timing.
A signal is sent at a timing of one frame before 0. When strobe light emission is performed, strobe light emission can be performed when all the pixels of the image pickup means 24 are exposed.

Then, after the lens is loaded, when the winding of the silver halide film 51 is started, a communication for starting the winding is sent. The digital CPU 20 writes and stores the captured image in a predetermined memory area of the storage means. Finally, the silver halide CPU10
After the completion of film winding, the digital CPU 20 waits for the end of image storage, issues a sleep request, stops the operation of the digital unit, and controls power saving so as to reduce current consumption.

As described above, in the camera according to the present embodiment in which the second control means 20 performs control subordinately under the initiative of the first control means 10, the camera is made for each function as exemplified in FIG. The control program subroutine is running. <
Each subroutine having a name in> is the above silver halide C
The PU (first control means) 10 and the digital CPU (second control means) 20 communicate communication contents composed of a header and subsequent data information as shown in the figure. Specifically, the number of bytes (length, format) differs according to each communication content. The numerical value in the first byte indicates the type of communication. The last byte is for a checksum. Here, the lower 8 bits when summed are represented by hexadecimal # A5.
By making the value H, it is determined whether or not the communication has been correctly performed.

The outline of the function of each subroutine is listed below. <DG_DSP>: Sends data required for display by the digital CPU. Sent when the digital CPU is activated, immediately after a zoom operation, when a mode change, rewinding, or the like is desired to be performed, or when the digital CPU is activated. Note that D_DGFCO corresponds to the number of the memory area, and the silver halide CPU determines the presence / absence of various switches and films, and specifies the memory area for storing and displaying an image with D_DGFCO.

<DG_1R>: Signals that 1RSW is turned on. <DG_AE>: Sends the photometric value at the end of photometry. <DG_AF>: Sends data on the presence or absence of a strobe and exposure at the end of ranging. The digital CPU determines the content of the communication and controls the ND filter.

<DG_2R>: Signals that 2RSW is turned on. <DG_SHT>: Informs that lens extension is completed, that is, shutter control preparation is OK. <One frame before light emission>: Precise timing is required, so a predetermined terminal (P_P in this example) is used instead of data communication.
The timing is transmitted based on a change in the edge of the BUSY terminal.

<DG_WD>: Communication before winding. Tell the date of shooting to put the date on the image. <DG_SLP>: Sleep request. Requests operation stop of digital section. <DG_CLR>: A request to delete a film-compatible image. It communicates when a new film is loaded and autoloaded, and erases the image corresponding to the previous film. However,
In the demo mode, overwriting is performed for each frame, so such erasure communication is unnecessary.

FIG. 7 is a table showing specific data processing of the number of frames and the memory area and areas such as flag names and table names used at that time. D_FCO: The number of frames of the film. D_DEMOFCO: Memory area for demo mode. D_DGFCO: Memory area for digital images.

When the battery is loaded or the barrier is opened, the number of frames stored in the non-volatile memory (EEPROM) is read out to the D_FCO, and the number of frames "41" for the demo mode is changed to the D_DEM.
Written to OFCO. After that, the process is divided into left and right processes based on whether there is a film or in the demo mode.

When there is a film, the number of frames D of the film
D_DGFCO is calculated based on _FCO. When 1RSW is pressed, D_FCO is set to D_DGFCO.
When the winding is completed, D_FCO is counted up.
D_FCO contains the number of frames to be shot next. D
When the display mode is set by pressing the SPSW, D_FCO-1, which is the number of frames shot immediately before, is set.
D_DGFCO is decremented when ZDSW is pressed, and incremented when ZUSW is pressed. "
1 "to D_FCO-1. DSPS
Even if W is pressed again to cancel the display mode, D_DG
The FCO does nothing.

In the demo mode without a film, the D_DGF is based on the memory area D_DEMOCO in the demo mode.
Calculate CO. D_DEMOF when 1RSW is pressed
Set CO to D_DGECO. When the image storage is completed after photographing, the D_DEMOFCO is counted up. D_DEMOCO contains the number of the memory area of the image to be captured next. When the display mode is set by pressing the DSPSW, the memory area number D of the frame captured immediately before is displayed.
_DEMOFCO-1 is set. When ZDSW is pressed, D_DGECO is decremented.
When it is "1", it is set to "45", and when it is "1", it is D_DEMO
FCO. As a result, the first frame of the film becomes a frame for demonstration shooting. D_DG when ZUSW is pressed
FCO is incremented, but D_DEMOFCO
When it is equal to "1", it is set to "1", and at most D_FCO-1. As a result, the frame of the film is displayed from the frame of the demo shooting.

When the display mode is released by pressing the DSPSW again, D_DGFCO + 1 is added to D_DEMOFCO
Set to. In the demo mode, even if the display mode is pressed by pressing the DSPSW and the display mode is released by pressing the DSPSW, D_DEMOFCO-1 → D_DGFCO, D
_DGFCO + 1 → D_DEMOFCO, and D_D
EMOFCO does not change. However, in the display mode, Z
When the display frame is changed to another frame in the demo shooting area by the DSW or ZUSW and then the expression mode is released, the memory area for the next demo shooting can be changed.

Next, the control procedure of the camera control program according to the present embodiment will be described with reference to the flowcharts illustrated in FIGS. FIG. 8 is a main flowchart of the camera control program. This control program is operated by a CPU as a first control means 10 for controlling the camera as a whole, and is executed while calling a plurality of subroutines as exemplified in FIGS. Specifically, when the main power supply of the camera is turned on, the main routine starts. And first,
At the same time as initializing a memory area such as a RAM (S1), each flag is reset to 0 (S2), and zoom is reset to a wide state (S3).

From step S4, the display is initialized (S4: (DSPCSET)), the demo mode is checked (S5), and photometry is performed (S6). In step S7, it is determined whether or not the rear lid of the camera body is closed and there is a film (S7). If not, the flag indicating the demo mode is set to 1 (S8), and the process proceeds to step S14. On the other hand, since the mode is not the demo mode, the flag is set to 0 (S9), the change of the rear lid is determined (S10), and if there is no change, the process proceeds to step S14. S11), auto-loading is performed (S12), and the process stands by until digital image clearing is completed (S13).

In step S14, it is determined whether or not the barrier of the camera body is open (S14). If not, the zoom is retracted (S15) and the display is turned off (S16).
The process returns to step S1.

On the other hand, if the barrier is open, display processing (S17), input of a key matrix (S18), and counting of display time (S19) are performed, and the time is determined (S20). Here, when 4 minutes have elapsed, the zoom is set to the wide state (S21), and the display is turned off (S2).
2) Returning to step S4, if 4 minutes have not elapsed yet, charging is performed (S23).

From step S24, it is first determined that the release operation is half-pressed (S24), and a predetermined release process is performed (S25: (RLS)). Then, it is determined whether or not it is the film end (S26). If not, the process returns to step S4. If it is the film end, rewind is performed (S28), and the process returns to step S4.

From step S29, a zoom SW operation is determined (S29). If there is a ZUSW or ZDSW operation, a predetermined zoom control is performed (S30), and the process returns to step S4. After the mode change process (S31: (MCHAN)), after stopping 32 msec. (S32), the process returns to step S7.

The flowchart of FIG. 9 shows a subroutine (RLS) relating to the above-described release processing. It is assumed that the details of this processing proceed according to the procedure shown in the figure, and here, an outline including a characteristic portion will be described. The following processing is performed using the above-described flags and tables. That is, following the temperature measurement and photometry performed by the thermistor for AF, determination of the demo shooting mode, battery check and charging for strobe light emission, and distance measurement and AE processing are performed. Then, taking into account close-up photographing and the amount of light and red eye at that time, focus adjustment and narrowing down are performed to photograph, and images are sequentially stored in a predetermined memory area.

Similarly, the flowchart of FIG. 10 is a subroutine (MCHAN) relating to the mode change processing of the camera according to the present embodiment, and is performed as follows using the above-described flags and tables. When the mode is changed, first, the control of the frame number of the corresponding digital photographed image is advanced while updating the display counter based on the operation of the zoom SW. If there is no zoom SW operation for a predetermined period, the process is started after clearing the zoom SW ON time counter. As long as there is no communication damage, the DSP (display) mode proceeds according to the procedure shown in the figure.

The flowchart of FIG. 11 shows a subroutine (DSPCTS) related to the setting processing of the display counter.
ET), the value of the display counter is set as shown in the drawing based on whether or not the camera is in the self mode, and then the zoom SW ON time counter is cleared to 0. In the flowchart of FIG. 12, a subroutine (TCOUNTDG) relating to count-up processing of the digital display time counter is performed.
In addition to the updating of the number of frames, the updating of the time counter is performed according to the procedure shown in the figure.

FIG. 13 is a flowchart showing a subroutine (L) relating to a display process of an image photographed digitally.
DISPDG), and is processed in the following procedure.
First, if the camera is not charging, the digital photographed image is displayed according to the request, the digital CPU is activated, and then the digital mode is displayed. After a predetermined display time has elapsed, the power supply to the digital CPU is turned off and the sleep mode is resumed. Let it be in a state.

FIG. 14 (a) shows a flowchart relating to the digital mode display processing. First, in the case of the demo mode, only the flags are set as shown in the figure, but other modes, for example, DSP ( In the case of the (display) mode, each of the flags is set by identifying the composition line mode, the film mode or the digital mode. at the same time,
In accordance with the flag, a mark indicating each mode as shown in FIG. 14B is displayed to notify the user.

In the film mode, the digital section does not start. Therefore, current consumption can be reduced, which is effective when the remaining battery power is small. The digital mode is a mode for communication with a personal computer, and the digital section is always kept activated. Use an external power supply when necessary.

Next, FIGS. 15A to 15D enumerate subroutines relating to the updating process of the memory area (D_DGFCO) of the camera of this embodiment. It should be noted that the setting and updating of the number of frames can be referred to together with the explanatory diagram of FIG. 4, and the conditions for updating the number of frames can be referred to the list of FIG.

The flowchart of FIG. 15A is a subroutine relating to the setting of the number of frames for digital display. The update condition in the demo mode is as follows: when the value corresponding to the address of the memory area is 41 frames or more, 45 frames are used. Is set to The flowchart of FIG. 15B is a subroutine related to the addition of the number of frames for shooting in the demo mode, and scrolls between 41 frames of the update condition and 50 frames.

The flowchart in FIG. 15C is a subroutine relating to the subtraction of the number of frames of the digital photographed image, and is updated at the 41st frame as an update condition in the demo mode.
Similarly, the flowchart of FIG. 15D is a subroutine related to the addition of the number of frames of the digital photographed image, and sequentially updates the number of frames up to the number of films in modes other than the demo mode.
In the demo mode, the camera updates the shot frame.

Finally, the digital C of the camera of this embodiment is
A time chart for PU activation and communication, and power supply control to the digital unit will be described with reference to FIGS. 16 (a) and 16 (b). In accordance with the timing shown in FIG. 16A, the activation and communication of the digital unit are performed. First, in order to activate the digital unit, the power supply control signal PWCNT of the digital unit is set to “L (Low)”, and power is supplied.
The digital CPU 20 is started by setting the reset terminal RESET of the PU 20 to “L” and releasing the reset state. Also to communicate, shake hand signal,
When a communication request is made with the change of READY from “H (High) → L” and the change of BUSY is changed from “L → H”, SDAT is synchronized with the SCLK clock timing.
A transmits data by A.

When the operation of the digital CPU 20 is stopped, a sleeve request is made at the RESET timing shown in FIG. 16B, and the digital CPU 20 is brought into a stoppable state. And PW
The power is turned off by setting CNT to 'H'.
