The output of this photometric circuit is therefore a photometric signal added with the film sensitivity signal, and this signal is input to the base of the transistor (TR,) via a buffer (B). The signal is then logarithmically expanded by a logarithm expansion circuit consisting of a transistor (TR,) and a capacitor (C1).

Here, in the camera that allows trimming according to the present invention, when the area to be printed on the film surface is reduced, for example in the trimming 3 mode, it is the same as in the normal shooting mode where no trimming is performed. When the image is enlarged to the desired size, the enlargement magnification increases. Therefore, blur and flare, which were not noticeable in the normal shooting mode, become noticeable. Therefore, in the camera of this embodiment, the minimum aperture value (that is, the limit value on the open side of the aperture) and the limit value on the slow side of the shutter speed are changed depending on the print range, and the depth of field is increased when performing cropping. At the same time, the shutter speed is increased to prevent camera shake. Note that in this embodiment, a lens shutter that also serves as an aperture is used, so if the minimum aperture value is increased, the shutter speed will be increased accordingly, but the present invention is not limited to this, and the trimming It may be configured such that only the minimum aperture value or only the limit shutter speed is changed depending on the situation.

Table m3 shows the photographing mode, minimum aperture value, and low-speed limit shutter speed in this embodiment.

Table 3 However, here, A vmax is the minimum aperture value, TvII
lin indicates the limit shutter speed on the low speed side. This is the first
It is shown in Figure 8. In Figure 118, the vertical axis is the aperture value, and the vertical axis is the time since the shutter starts opening. In normal shooting mode or trimming 1 mode, the aperture (F value) is 2.8, as shown by (l\). The aperture can be opened or the shutter speed can be slowed down to a combination of shutter speeds of 1/30.

In the trimming 3 mode, as shown in (B), the aperture can only be opened or the shutter speed can be slowed down to a combination of an aperture (F number) of 5.6 and a shutter speed of 1/60. Furthermore, in the close-up mode, only a combination of an aperture (F number) of 16 and a shutter speed of 1/1000 can be set. If proper exposure cannot be obtained with the combination of aperture and shutter speed limited as described above, a flash is automatically emitted. As shown in the lower time chart of Fig. 18, for example, in the case of trimming 2 mode, if an aperture (F number) of 5.6 and a shutter speed of 1760 result in underexposure, the automatic focus adjustment circuit (AF) The control microcomputer (
A signal is emitted from the output terminal (POs) of the CM C') to start the flash, and at the time T2 when the shutter is opened to an aperture (F value) of 5.6, the output terminal (POs) is emitted.
, ) is emitted to initiate the closing operation of the lens shutter.

Here, in this embodiment, the exposure value Ev for switching to flash emission is also configured to be changed depending on the shooting mode. Table 4 shows the relationship between this photographing mode and the exposure value at which flash emission is switched (this is referred to as exposure value Eve).

fjS4 In front unit, exposure value Ev (or Evc) is calculated by calculating subject brightness by BV and film sensitivity by S.
v, aperture value is Av, and shutter speed value is Tv, it is defined as Ev (or Eve) = Bv + 5v = Av + Tv.

FIG. 19 shows the relationship between the fringe value and the shutter speed value when switching to flash light emission.

In Fig. 19, the vertical axis shows the aperture value, the horizontal axis shows the shank speed value, and in the case of normal shooting mode without trimming and trimming 1 mode, the exposure value E is as shown in (Da).
Although the flash is not emitted when v is 8 or more, in the trimming 2 mode, the flash is not emitted only when the exposure value Ev is 10 or more as shown in (Ea). Furthermore, in the case of trimming 3 mode, the flash is not emitted only when the exposure value Ev is the second or higher like (Fa), and in the case of close-up mode, the exposure value Ev is 18 as shown in (Fa). The flash will fire only under the above conditions. This is because when the magnification during enlargement is large, the aperture is made as small as possible to deepen the depth of field.

Next, the control microcomputer (C,
The operation of MC) will be explained based on ν1 based on FIG. FIG. 20 is a 70-chart showing the operation of the camera control microcomputer (CMC) of this embodiment shown in FIG. 16. In FIG. 20, the circuit is reset by a power-on reset when a battery is installed, and then, in step #0, the input/output ports and memory of the control microcomputer (CMC) are all initialized. Here, all output terminals except the output terminal (po, .) of the control microcomputer (CMC) are initially set to output L'', and the shooting mode is initially set to normal shooting mode without cropping or close-up. Jt1g is set. Next step #

Then, in step #2, the signal at the output terminal (po,) of the control microcomputer (CMC) is raised, and the external pressure circuit of the flash circuit (FL) is started to operate. Next, in step #3, external interrupts to the interrupt terminal (INT) of the control microcomputer (CMC) are permitted, and in step #4, the normal stop state is entered.

Then, by pressing the shirt release button (4), pressing the trimming setting button (8), winding the film, and opening/closing the back cover,
When an external interrupt is applied to the interrupt terminal (INT) of C), other external interrupts are prohibited in step #5, and the process proceeds to step #6.

Step #6 (Steps will be omitted below) detects the open/closed state of the winding switch (S4) connected to the input terminal (PI,) of the control microcomputer (CMC), and detects whether the switch (S4) If it is open (OFF) and the film winding is completed, proceed to #7 and input the DX hood information regarding the film sensitivity of the switch (CAS) from the input terminal (PIDX). Then, in #8, the input terminal (PI) is connected to the key switch (S3) that is linked to the trimming setting button (8).
), enter information regarding the shooting mode (cropping size). The details will be described later.

Next, in #9, the open/closed state of the i-lid switch (S5) is detected from the input terminal (P I 5), and if the back cover is open and the back cover switch (S5) is closed, (If ON), proceed to #10 and set the count value of the film counter that counts the number of shots of film to "O".

If the back cover is closed in #9 and the back cover switch (S5) is open (in the case of OFF), the process proceeds to #11 without passing through #10.In #11, the control microcomputer (CMC)
) to the display microcontroller (DMC) from the output terminal (PO, ) for display rewriting, the information necessary for display is transmitted, and the information necessary for display is transmitted to the liquid crystal display device (LCD, ) (
A display is made on the LCD 2).

Then, #2 is the photometry switch (Sl) which is linked from the input terminal (PI, ) to the shirt release button (4).
If the open/closed state of the photometering switch (S, ) is detected, it returns to #1 (OFF) and enters the normal stop state of #4. If the photometry switch (S,) is closed (
ON), #13 turns down the output terminal (PO, ) No. 13 to stop boosting the flash circuit (FL). Then, in #14, the automatic focus adjustment circuit (AF) is activated by the start signal from the output terminal (Pot) of the control microcomputer (CMC), and in #15, the automatic focus adjustment circuit (AF) is activated by the start signal from the output terminal (Pot) of the control microcomputer (CMC).
r2), the open/closed state of the release switch (S2) linked to the shirt release button (4) is detected. Here, if the release switch (S2) is open (OFF), it returns to #2 and repeats the operations from #2 to #15, and the shirt release button (4) is pressed to the second step. Wait until the release switch (S2) is closed. If the closing of the release switch (S2) is detected in #15, the process proceeds to the shank release operation from #16, which will be described later.

On the other hand, if it is detected that the winding switch (S,) is closed (ON) at #6, the winding of the film has not yet been completed, so #38I is rubbed and the flash circuit (FL) is activated. Stop the external pressure of #39
Start the winding routine. At #39, the motor drive circuit (MD) is driven by the signal from the output terminal (PO9) of the control microcomputer (CMC) to start the film winding motor (M) and start winding the film. Then, at #40, the opening/closing state of the winding switch (S,) is detected to detect the completion of film winding,
When film winding is complete, press the winding switch (S,
) is released (OF F ), the motor (M) is driven. Open the winding switch (S4) with #40 (
When OFF) is detected, the rotation of the motor (M) is stopped in #41 to stop film winding, and the process proceeds to #42.

#42 is the input terminal (P) of the control microcomputer (CMC).
I6) detects the open/closed state of the film detection switch (S6), and if no film is loaded and the film detection switch (S6) is closed (ON), #4
In step 5, the information necessary for display is transmitted from the control microcomputer (CMC) to the display microcomputer (DMC), and the process returns to #1.
At #4, the normal stop state occurs. When it is detected in #42 that the film is being wound and the film detection switch (S6) is open (OFF), the process proceeds to #43 and detects the open/closed state of the camera back switch (S). Ru. Then, with #43, the camera back is opened and the camera back switch (S,
) is closed (ON), the process proceeds to #45, transmits the information necessary for display from the control microcomputer (CMC) to the display microcomputer (DMC), returns to #1, and normally stops in #4. state. Furthermore, if the back cover is closed in #43 and the back cover switch (S5) is open (OFF),
Proceed to 44 and set the film counter's cap value to "1"
Then proceed to #45 and transfer the information necessary for display from the control microcomputer (CMC) to the display microcomputer (DMC).
It returns to #1 and enters the normal stop state at #4. That is, this configuration prevents the film counter from incrementing when the back cover of the camera is opened or when no film is loaded.

Ask your dog about the release routine from #16. In #16, first, a photometric signal that takes into account the film sensitivity is input from the A/D converter (A/D> to the input terminal (PIAD) to the control microcomputer (CMC). Therefore, this photometric signal is converted into photometric data. Evm.In #17, in the camera of this embodiment, the exposure value Eve at which the flash is switched is different depending on the shooting mode as shown in FIG. EνC is read from the ROM. Then, in #18, the photometry data Evn+ is compared with the exposure value Evc for switching to flash photography, and Evm>Ev
If e, proceed to #25, which will be described later. On the other hand, Evm>E
If it is not vc, the metering data is lower than the exposure value Evc at which switching to 7-lash shooting is performed, so #1
9 is the input terminal (PI,
) to determine whether the main capacitor for flash emission in the flash circuit (FL) has been fully charged. If this charging is completed, proceed to #20 and set a flash photography flag instructing flash photography. If this charging is not completed yet, #1
Return to #4 and wait for this charging to complete.

In #21, it is determined whether the shooting mode is set to close-a-knob mode, and if it is not close-up mode, in #23, the input terminal (PIAF) is sent from the automatic focus adjustment circuit (AF) to the control microcomputer (CMC). A signal related to the subject distance is inputted via. On the other hand, if it is determined in #21 that the close-up mode is set, the process proceeds to #22 and sends the "F(" signal from the output terminal (PO2) of the control microcomputer (CMC) to the automatic focus adjustment circuit. (AF) to forcibly convert the subject distance signal into a signal corresponding to the closest distance.Then, in #23, similarly, the automatic focus adjustment circuit (AP) is transmitted to the control microcomputer (CMC).
) is inputted with a signal related to the object distance via an input terminal (PIAF).

In #24, the control microcomputer (CMC) connects the terminal (PIA
The value corresponding to the subject distance signal input from F) is stored in the ROM.
, and set it in the light emission timing timer provided inside the control microcomputer (CMC). this is,
This is because, when performing flash photography, the aperture value is determined by the 7-ratio mechanical mechanism according to the subject distance, and the 7-ratio flash timing is determined according to the aperture value, as shown in FIG. 18. Next, in #25, the control microcomputer (CMC) outputs the value according to the shooting mode to RO.
Read from M and set it to the exposure limit timer. This is because in this embodiment, the minimum aperture value and minimum shutter speed are limited depending on the shooting mode.

#26 is the control microcomputer (CMC) output terminal (PO
An imprint signal is output from ll), and the information of each code is imprinted on the outside of the screen of the film depending on the on/off state of the light emitting diode (32a) corresponding to each hood. Then, at #27, the shirt starter magnet (SMg) is excited by the rise of the signal from the output terminal (po, ) of the control microcomputer (CMC), and the series magnet is excited by the signal from the output terminal (POlo). )
(RMg) is started to operate, and the photographing lens is extended after a certain period of time. Then, in #28, the control microcomputer (
The open/closed state of the count switch (S,) is detected from the input terminal (p r,) of the count switch (CMC), and the count switch (
S7) is closed. Here, when the count switch (S7) is closed at the beginning of the shirt release operation, the process proceeds to #29 and the integration of the exposure amount is started. Here, the photometric system of this embodiment has a sub-diaphragm whose aperture diameter changes depending on the amount of light transmitted through the lens shutter, and charging of the capacitor (C1) is started when the integration of the exposure amount starts.

At #30, it is determined whether or not the flash i-shadow 7 lag that instructs flash photography is set, and if the flash photography flag is set, the process proceeds to #31 and starts the above-mentioned light emission timing timer. At the same time, enable timer interrupts and proceed to #32. If the 7-lash shooting flag is not set in #30, proceed directly to #32. Then, in #32, an exposure limiting timer, which is set in advance for one hour according to the appropriate exposure amount, is started, and in #33, it is continuously determined whether or not this timer has exceeded 70-. Here, in this embodiment, since a lens shutter that serves both as an aperture and a shutter is used, the fringe value and shutter speed value are set at the same time by one exposure limiting timer. The aperture and shutter speed may be configured to be controlled separately so that the combinations can be changed in various ways.

When an overflow of the exposure limit timer is detected in #33, the process proceeds to #34 and the control microcomputer (C
The signal at the output terminal (po,) of the MC) rises, the transistor (TR,) becomes conductive, and the shirt starter magnet)
(SMg) is forcibly demagnetized, the shutter that also serves as an aperture is closed, and the exposure is completed. After waiting for a predetermined period of time for the shutter to finish closing in #35, the winding routine starts from #39. return.

Here, the timer interrupt routine in #31 is shown in FIG. 21. First, when a timer interrupt occurs, the timer interrupt is disabled in #36, and in #37, the output terminal (pos. ) rises, a 7-lash light emission signal is issued, the flash is emitted, and the process returns to the original step.

Next, regarding the operation of step #8 in FIG.
It is shown in more detail in the figure. Figure 22 shows 1 and 1. First,
#8-1 detects the open/closed state of the trimming key switch (S), and if the key switch (S3) is closed (ON), proceeds to #8-2 and changes the trimming mode register by one level. Then proceed to #8-3. If the trimming key switch (S3) is open in #8-1, #8
Proceed to #8-3 without going through -2. In #8-3, it is determined from the sensitivity of the loaded film input from the switch (CAS) to the input terminal (PIDX) whether or not the film sensitivity is 15O100O or more.

And if the sensitivity of the film loaded with VC is 150
If it is 100O or more, the process proceeds to #8-4, where it is determined whether the mode is below trimming 2 mode, and if it is below trimming 2 mode, the process is changed to normal photography mode without trimming at #8-5.

On the other hand, the sensitivity of the film loaded in #8-3 (I
If it is determined that the S O is less than 1,000, proceed to #826, and then increase the sensitivity of the film to 5O400.
It is determined whether or not the above is satisfied. If it is above ■5o4oo, proceed to #8-7 and it is determined whether or not the trimming mode is below 3 mode, and if it is below the trimming mode 3 mode, proceed to #8-7.
-8 returns you to normal shooting mode without cropping. #
If the film sensitivity is not 15O400 or higher in 8-6,
And if the trimming mode is not lower than 3 in #8-7, the photographing mode is not particularly changed.

Therefore, according to this embodiment, as shown in FIG. 23, if the sensitivity of the loaded film is less than 15O400, each time the trimming setting button (8) is pressed, the normal shooting mode is changed to the trimming 1 mode. , from trimming 1 mode to trimming 2 mode, from trimming 2 mode to trimming 3 mode, from trimming 3 mode to close-up mode, and from close-up mode to normal shooting mode. (If the trimming setting button (8) is pressed from the trimming 2 mode, the mode returns to the normal shooting mode and the trimming 3 mode and close-up mode are not set.)

Furthermore, if a high-sensitivity film of 1501000 or more is used, pressing the trimming setting button (8) from the trimming 1 mode returns to the normal shooting mode, and the trimming 2.3 mode and close-up mode are not set. This is because the higher the sensitivity of the film, the coarser the grain, so cropping and close-up photography that require a large enlargement magnification become less desirable as the sensitivity of the film increases.
In this embodiment, the trimming limit is set differently depending on the film sensitivity.

Next, the operation of the display microcomputer (DMC) of this embodiment will be explained using fJS charts 70- from Fig. 24 to Fig. 26. First, the display microcomputer (DMC
), all input/output ports and memory are initialized in #46. For example, the clock mechanism built into the display microcontroller (DMC) is initially set to "January 1, 1985".
The photographing mode is initially set to the normal photographing mode, and the count value of the film counter is initially set to "0". Next, #4
At step 7, the stored contents of data necessary for display and imprinting on film are decoded. And #48
This data is transmitted to the liquid crystal drive circuit (LCDR) and displayed on the liquid crystal display device. Respective necessary information is displayed by f(L CD , ) (L CD 2). Then, in #49, all interrupts are enabled, and in #50, the normal stop state is entered.

FIG. 25 is a flowchart showing a timer interrupt to the display microcomputer (DMC), and this timer interrupt is configured to occur every second. First, when a timer interrupt occurs, calendar calculation is performed based on the clock mechanism built in the display microcomputer (DMC) in #51, the calculated data is decoded in I52, and the liquid crystal is driven in #53. It is output to the circuit (LCDR), the display is changed, and the process returns to the original step in #54.

Furthermore, FIG. 26 is a flowchart showing an interrupt for rewriting the display and an interrupt for imprinting a code on the film. First, when the input signal to the interrupt terminal (into) of the display microcomputer (DMC) rises and an interrupt occurs, the timer interrupt shown in FIG. 25 is inhibited at #55.

Here, if a timer interrupt occurs after #55, it is stored in memory, and the interrupt is configured to be executed immediately after the timer interrupt is enabled. Then, in #56, display data such as the count value of the film counter and the shooting mode are input to the input terminal (pi).
D), the data and the 81-inch data are decoded in #57, and the decoded data is outputted to the liquid crystal drive circuit (LCDR) in #58 to display the liquid crystal display device (LCD). Change the display of CD 2) and press #
At step 59, the timer interrupt is enabled and the process returns to the original step.

On the other hand, the interrupt terminal (in
When the input signal to t2) rises and an interrupt occurs, the timer interrupt shown in FIG. 25 is prohibited in #61,
At #62, the open/closed state of the date print selection switch (S8) connected to the input terminal (pil) is detected. If this date print selection switch ($8) is open and date print is not selected, #
The process proceeds to #63, decodes the data corresponding to the code that prohibits printing of the date, and proceeds to #65. On the other hand, #6
If the date print selection switch (S6) is closed in step 2 and date printing is selected, the data corresponding to the date to be printed is decoded in step #64, and the data corresponding to the date to be printed is decoded in step #6.
Proceed to 5.

In #65, the sensitivity of the loaded film is read from the input terminal (piDX) connected to the switch (CAS), and in #66, the code imprinting time (i.e., the light emitting diode) is determined according to the read film sensitivity. (32a)) is determined, and imprinting of the hood is started in #67. When the imprinting time determined in #68 is counted, the imprinting is finished in #6, and the progress timer interrupt is permitted in #59.

Next, we will explain the configuration of the automatic printer included in the system of this embodiment, which automatically prints the film photographed by the camera of this embodiment onto photographic paper.
As shown in the figure. In Fig. 27, (LA) is a lamp for printing, (CF) is a color filter for color balance adjustment corresponding to the three primary colors of red, green, and blue, and (EL) is a lens. The emitted light is filtered through a color filter (
CF) and the film (F) at the printing position through the lens (EL). Then, the light transmitted through this film (F) is projected onto photographic paper (PP) via a printing zoom lens (PL) to perform printing.

The configuration of this automatic printer will be explained below along with its operation.

First, (50) is a lamp control circuit that controls the lighting/extinguishing state of the lamp (LA). It is also used for reading codes imprinted on film, color balance, and photometry for determining exposure.

Reference numeral (52) denotes a film conveyance device that feeds the film photographed by the above-mentioned camera toward the carrier of the printer, and feeds the film (F) to the right in the figure. And of the film being fed out in this right direction? Quality is C

) to the film transport device (52).
) falls, the film advance is stopped and one frame of film is just positioned to be printed. Further, the film frames that have been printed are sequentially wound up by a film winding device (not shown).

Then, when the film feed is stopped, the code reading device (58) is activated by the signal (b) issued from the film transport device (52), and the film (F
) is read by a line sensor (60). That is, the code reading device (58) reads information such as the photographing mode of the frame to be printed, whether or not to print 84 size, and the date to be printed. The shooting mode information read by the code reading device t (58) is transmitted as a signal (c) to the printing zoom lens control device (62) which sets the printing magnification of the printing zoom lens (PL) and the photometry It is transmitted to a photometric zoom lens control device (64) that sets the magnification of the zoom lens (ML). And both zoom lenses (M
For L) (PL), the magnification is set according to the shooting mode information, and if cropping is specified at the time of shooting, the photometry range on the frame and the enlargement magnification on the photographic paper are determined according to the cropping size. It will be done. With this configuration, even if a mode that specifies cropping is set at the time of shooting, it is possible to accurately measure only the area to be printed, and it is possible to enlarge the image to the specified size regardless of the cropping size. can be printed.

Then, the magnification setting of the photometric zoom lens (ML) by the photometric zoom lens control device (64) is completed.

Then, exposure calculation is performed by the exposure calculation circuit (66) in response to the signal (d) indicating the completion. This exposure calculation is performed based on the output of a photometry circuit (68) that receives light from the frame at the print position via a photometry zoom lens (ML), and the color balance and exposure amount according to that frame are calculated. be done. The color balance information calculated here is transmitted as a signal (e) to the filter control device ff1 (70) and used for adjusting the color balance, while the exposure amount information is transmitted as a signal (r) to the lamp control circuit (70). 50) and used to determine the amount of light emitted from the lamp (LA). Further, a signal (g) indicating the end of photometry is also transmitted from the exposure calculation circuit (66) to the lamp control circuit (50), and the lamp (LA) is temporarily turned off.

Ru.

Next, the filter control device (70) sets a color filter (CF) according to the color balance information from the photometric circuit (68), and when this setting is completed, the filter control device (70) indicates that the filter setting is complete. A signal (h) is emitted.

This signal (11) is transmitted to the lamp control circuit (50) and the shutter control device (50), which controls the opening and closing of the shutter (PS) placed in front of the photographic paper (PP) at the printing position.
72), and a date print control device (
74) respectively. Here, information regarding the date printed on the photographic paper is obtained from the food reader (58).
is decoded via a decoder (76) and input to a date print control device (74), and the date print control device (74) uses this information to print a date on a date plate (78) indicating the date to be printed. Set the year, month, and day.

Then, the shutter control device (72) starts opening the shutter (PS), and the lamp control device (50) receives this signal (11). After a certain period of time from when the shutter (PS) is fully opened, the lamp (LA) is turned on and printing is performed. On the other hand, if date printing is selected by the code imprinted on the film, the date printing control device (74
), the lamp (LD) is turned off after a certain period of time from when the signal (h) is input until the shutter (ps) is fully opened.
Turn it on and print the date. Here, (DL)
is a date print lens, and the date set on the date plate (78) is the date print lens (DL).
) is projected onto the photographic paper screen and printed. If printing of the date is not selected by the code imprinted on the film, the lamp (LD) will not be lit and the date will not be printed.

Here, the lighting time of the lamp (LD) for date printing is controlled by the date print control device (74) to be a constant time, and the lighting time for the date printing is controlled to be shorter than the burning time by the lamp (LA). The amount of light emitted from the lamp (LD) is set. On the other hand, the lamp for film printing (LA) is configured such that the lighting time and light intensity are controlled by a lamp control circuit (50) according to exposure amount information.

Then, when printing by the lamp (LA) is finished,
The lamp control circuit (50) outputs an exposure completion signal (j) after turning off the lamp (LA). In response to this exposure completion signal (j), the film transport device (52) starts feeding the film, and the shutter control device r! ! (7
2) causes the shutter (ps) to close.

Furthermore, in response to this exposure completion signal (j), the photographic paper transport device (80) sends out the photographic paper (PP) to the right in the figure.
Be prepared for dog prints. Also, this exposure completion signal (j)
The screen edge detection device (56) and the code reading device (
58), the exposure calculation circuit (66), and the filter control device (70) are each reset to prepare for the next print. Then, the printed photographic paper is sequentially stored in a photographic paper storage device (not shown), and the printing process is performed.

Note that in the camera of this embodiment, the printing date is recorded on the film in the form of a code, so it is difficult to recognize the printing date even if you look at the film as it is. When using reversal film that is rarely printed, the date is of little use even if the date is imprinted on the film as a code.

Therefore, in case a reversal film is used like this, a date imprinting device is built into the camera that imprints the date as a numerical value on the screen of the film as in the past. The date may be configured so that the date is imprinted on the film as a numerical value by this date imprinting device. Here, in order to determine whether a normal negative film is loaded or a reversal film is loaded, it is sufficient to use the film latitude information among the information recorded in the film cartridge. Therefore, The switch of this embodiment (C
Among the film sensitivity information input from AS), information related to film latitude (for example, exposure

t, just do it. Alternatively, the date imprinting device may be manually selected depending on the film loaded.

Furthermore, since printing is not normally performed in the case of a reversal film, it may be configured to prohibit switching to the trimming mode when it is determined that a reversal film is attached. In the example camera, the trimming size can be changed to three types, and the minimum F value (aperture diameter with large fi) and maximum shutter speed are changed according to each trimming size. The invention is not limited to this, and depending on whether trimming is performed or not, the minimum FI itself? 1 word/! +J'F%+Near□,

It may also be configured as follows. In addition, such a limit value may be changed, and the value for issuing a warning such as a camera shake warning may be changed depending on whether or not trimming is performed. Furthermore, in this embodiment, the flash was configured to fire automatically if proper exposure could not be obtained even when the shutter speed reached a limited maximum value. In such a case, the light emitting part of the flash may be configured to protrude from the camera body to encourage the use of the flash.

In addition, for cameras with automatic exposure 11i17111 modes, in the case of the aperture-priority shutter speed automatic control mode that prioritizes the aperture over the set value, restrictions are applied depending on whether or not cropping is performed to the set aperture value. In the case of a program mode in which the aperture is automatically controlled and a shutter speed priority automatic aperture control mode, the calculated aperture value may be configured to be limited.

Furthermore, although the camera of this embodiment is configured so that the aperture and shutter speed change in a triangular shape as shown in FIG. In this case, the height of the trapezoidal shape may be limited to limit the embossed pattern.

Furthermore, although the automatic printer of this embodiment is configured to print data at the corners of the area where the subject is printed, the invention is not limited to this; The image may be configured to be printed in the white frame. Furthermore, if data is also printed within the area where the subject is printed, the color of the printed data may be changed so that the data can be easily distinguished by tq. The configuration may be such that the position is searched for and the data is printed at that position. The optical system for data printing is adjusted so that the position and size of the printed data are adjusted according to the print size, making it easy to check the printed data and minimizing the impact on the printed subject. You may choose not to have one.

Furthermore, the code imprinted on the film may be configured to be imprinted as a magnetic hood on a magnetic recording layer coated on the film. The data imprinted as a code is not limited to the photographing date as in the embodiment, but may also be hour, minute and second data, photographic exposure data, serial number, etc.

Incidentally, in the automatic printer of this embodiment, the printing optical system and the photometric optical system were provided separately.
For example, a photometric light-receiving element may be placed above the shutter (ps) shown in FIG.

In addition, in the above embodiment, the imprint data is configured to be imprinted outside the photographed screen, but the imprint data is not limited to this, but may be placed in a predetermined corner or near the bottom of one screen to be photographed. A shading means is provided to block light from the subject from entering the distribution area, and the shading means is used only when trimming is selected or always.
It may be configured such that the imprint data is imprinted in the light-shielded area.

Furthermore, in the above embodiments, liquid crystal display devices were used for the display within the 7-eye field of view and the display on the top surface of the camera, but the invention is not limited to this. For example, a display using a light emitting diode may be used. You can go. Furthermore, in the above embodiment, even in the normal shooting mode in which no cropping is performed, the liquid crystal display device on the top of the camera displays a display according to the area to be printed. It is also possible to eliminate the display and display the display according to the range to be printed only in the trimming mode. In the above embodiment, even when the trimming mode is set, the magnification of the viewfinder is not changed, but the area to be printed is displayed, but the area outside the area to be printed is displayed on the LCD. N
It may be completed.

Further, in the above embodiment, a push button (8) is provided for setting the photographing mode, but a slide switch or a changeover switch may be used instead.

In the above embodiment, when the close-up mode is set, the photographing lens is set to the closest position, but a close-up position may be provided instead of the closest position. .

Further, in a camera in which the focal length of the photographing lens can be changed, the lens may be configured to be set to the long focal length side when the close-up mode is set.

According to the present invention, the display pattern of the display means is slightly deformed and the trimming range is displayed within the 7-eye field of view. All that is required is to provide a display means to display the image and configure each image display means to perform display according to the set mode, so it is possible to perform smart display at a low cost, and the display is also easy to understand. .
