Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera, and more particularly to a camera capable of switching between a normal i shadow mode and a v1 trimming mode, which has a narrower printable range.

Conventionally, the above-mentioned camera has already been proposed in Japanese Unexamined Patent Publication No. 54-26721.

The camera proposed in the above publication is configured so that when +7 printing mode is specified, a horizontally long range is printed by reducing the normal shooting range by the same ratio both vertically and horizontally. has been done.

However, in order to obtain a vertically long print using such a camera, the camera must be rotated 90 degrees and photographed in a so-called vertical position. However, when photographing in this vertical position, there is a drawback that operating members such as a chanterelle release button arranged on the top surface of the camera body become difficult to operate, resulting in poor operability of the camera. Furthermore, the 7-ray flashlight is usually mounted on the camera body so that it illuminates the subject from above the camera body, so if you use the flash to shoot vertically, the printed photo will be illuminated from the horizontal direction of the subject. Since the light is being illuminated, the shadows may look unnatural and the photo may look strange.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a camera that can easily obtain portrait-oriented prints without changing the camera's posture, and does not result in poor operability or unnatural-looking photographs. It's about doing.

In order to achieve this objective, the present invention is based on the idea of obtaining a vertical print by using the trimming mode V of a camera having the above-mentioned trimming mode. , a mode selection means for selecting between the normal shooting mode and a cropping mode in which the printed area is narrower than the normal shooting mode, and when the trimming mode is selected, 1. The present invention is characterized by comprising a trimming instruction means for storing a signal instructing to print the range on the film.

Therefore, according to the present invention, it is possible to obtain a portrait print by specifying the trimming mode.
@1 There is no need to change the posture of the camera in order to get a print, and the operability of the camera becomes worse.
This eliminates the possibility of obtaining unnatural photographs.

13 to 17 are 70-charts showing the operation of the microcomputer (CPU). Microcomputer (CPU)
Normally, in order to reduce power consumption, the device is in a so-called standby state (not shown) in which unnecessary internal operations are stopped. Therefore, as mentioned above, the switch (Sl
) etc. When an interrupt is applied from the interrupt terminal (INT, ), the microcontroller (c p u > starts its operation.) First, when an interrupt is applied from the interrupt terminal (INT, ), Disable timer interrupts (step #1),
Prevent the following processing from being interrupted by timer interrupts.

Next, check whether the interrupt is caused by the hoisting switch (S4) from (P I , ) + (step #2),
If the hoisting switch (S4) +
Enter the winding routine. If the interruption is not caused by the winding switch (S4) (step #3), it is determined whether or not it is caused by opening the backing, and in that case, proceed to step #4 and set the film counter to 0''. Make it.

Hereinafter, in steps #5 to #8't', the cause of the interruption is confirmed by checking the input port (PIX) in order. Then, if this interrupt is caused by the switch (Sl), the first
Proceed to the photometry routine shown in Figure 4. Also, in step #6r, if this interrupt selects the trimming selection button (3) from 11:2 to 2 inches (S in), change the shooting mode. First, press the switch (S,). If it is determined that the interruption is due to an operation, the process proceeds to step knob #10, where it is determined whether or not the trimming mode is currently specified, and if the trimming mode is not specified, the process proceeds to step #12.

Furthermore, in step #7, this interrupt is set to the self-timer setting (S,
), set the self-timer mode in step #11, and in step #8, set the self-timer mode with the switch (S,) linked to the imprint mode switch button (2), use the Stereo knob #9 to set the self-timer mode. Change the embedded mode in sequence.

Then, once you have finished checking such interrupts, you can

By outputting R,)(D R2)(D R,) to the liquid crystal display device d(L D ,)(L D 2)(L D ,), the self-timer setting state and trimming mode can be changed. The presence or absence of selection, imprint data, etc. will be displayed.

Thereafter, timer interrupts are enabled in step #25. If an interrupt request is generated by the timer during the above processing, the interrupt will be generated at this point.

If there is no timer interrupt, it returns to the state of rffi after entering the interrupt from the it1 interrupt terminal 'T-(INT,).

If the switch (S,) is turned on in step #5,
fjS14 performs processing according to the photometry routine shown in FIG. In the photometry routine 1 shown in FIG. 14, first,
Step #26 stops boosting the voltage in the control circuit (FC), and step #27 stops the voltage boost at the output terminal (po,).
By setting the voltage to °L'', the transistor (TR,) is made conductive and power is supplied to each circuit from the power supply line ('cc).Here, the measurement circuit (LM) is connected to the power supply line (Vc).
When power is supplied from c), photometry starts. and,

The AF start signal is output from the amplifier #29 through the output terminal (PO, .

) to start the distance detection operation.

Next, in step #30, the date and time displayed in the display mode of the liquid crystal display (LD) is reset, and in step #31, the microcomputer (CPU) corresponding to the selected imprint mode is reset. By outputting data from the calendar timing function to the liquid crystal display device (L D ), the imprint data set at that time is displayed.

In steps #32 and #33, the switch (S2) is ON.
This is a routine that waits until the shirt release button (1) is pressed until the 2F sentence is reached, and the release switch (
When S2) is turned on, the process moves to the release routine shown in FIG. If the photometry switch (Sl) is turned off without the release switch (S2) being turned on, the time display mode is set again in which the date, hour, and minute are displayed in step #34, and the date, hour, and minute are displayed in step #35. By outputting data from the calendar timekeeping function of the microcomputer (cpu), the display on the liquid crystal display (LD) is changed to display the date, hour, and minute. Then step #36
Then, the timer interrupt is enabled and the process returns to the state before entering the interrupt routine from the interrupt terminal (INT).

When ON of the release switch (S2) is detected in step #32, the process advances to step #37 in Figure 1fi15, where the operation of the distance measurement and lens control circuit (AF) is completed and the AF completion signal is sent to the input terminal (p r , , ) are entered, and then proceed to the next step. When the AF completion signal is input, the process proceeds to step #38 to determine whether it is in self-timer mode. If so, it proceeds to step #3 and after 10 seconds, if it is not self-timer mode, it immediately Proceeding to step #40, the release signal is output from the output terminal (po2) to the exposure calculation control circuit (EC), and in step #41, a signal is output from the output terminal (pos) to start the lens start magnet. (RMg) is excited to start extending the lens and start the release operation.

When the lens start magnet (RMg) is excited, the lens begins to move one step to adjust the focal point, and the amount of movement is monitored by the distance measurement and lens control circuit (AF), based on the calculation result of the subject distance. The lens is stopped at an appropriate position by a lens stop magnet (LMg). When the lens is stopped, a distance signal related to the subject distance is sent from the distance measurement and lens control circuit (AF) to the exposure calculation control circuit (EC), and when this distance signal is input, the exposure calculation control circuit (EC) A shutter control signal is sent to the shutter control circuit (SC). The shutter control circuit (SC) excites this shutter control (shank control magnet (SMg) when receiving the signal H, and the shutter opening operation is started. On the other hand, inside the exposure calculation control circuit (EC), the demagnetization of the shutter control magnen) (SMg) and the light emission timing of the 7 ranoshu (8) are calculated based on the exposure calculation results and the flashmatic calculation results based on the distance signal. , when it becomes appropriate, it outputs to the shutter control circuit (SC) and the 7-lash control circuit (FC).

Furthermore, the microcomputer (c p u ) performs exposure control by the exposure calculation control circuit (EC) (during which time, data is imprinted and a mark is placed on the film indicating that photography has been performed in trimming mode). Record to.

First, in step #42, it is determined whether or not data forwarding is turned off, and if it is not, step #42 is performed.
43, the output signal of the output terminal (PO,) is set to "14" for an appropriate time to cause the lighting lamp (LP) to emit light (steps #44 and #45).

Next, in step #46, it is determined whether or not the trimming mode is set, and if it is the vertical trimming mode, the lamp (LE) is emitted by the output signal from the output terminal (PO,) in step #47. and imprint marks indicating that it is in vertical trimming mode on the film (steps #48 to #4), and in step #50, the exposure completion signal from the exposure calculation control circuit (EC) is transferred to the input terminal (P
After waiting for input to T, , , ), the process returns to FIG. 13 and proceeds to the winding routine.

In the winding routine of FIG. 13, first, in step #15,
The film winding motor (M) is started by the winding signal from the output terminal (PO6) of the microcomputer (CPU), and winding continues until the switch (S4), which is turned off when winding of one frame is completed, is turned off. (Step #16>. Then, when the winding operation for one frame of film is completed and the switch (S4) is turned off, step #17
In order to turn off the hoisting motor (N1), a brake signal is generated from the output terminal (po,), and the brake is applied to stop the motor.

Next, in step #18, the 7 runciu control circuit (FC)
The boosting operation is restarted, and "1" is added to the film counter in step #19. Here, if the camera's 'g &
I am afraid that it was detected in step #20 that the
If it is detected in step #21 that the film is not wound, the film counter is set to "0" in step #22 so that the count value does not advance.

Then, in step #23, the time display mode is reset, and in step #2.1, the output is output to the driver circuit <DR,).

Each of the signals is transmitted to a photometric zoom lens control device (64) that switches the magnification of the photometric zoom lens (ML). And both zoom lenses (ML>
In (PL), when the vertical trimming mode is specified at the time of photographing, the photometry range on 7 frames and the enlargement magnification to photographic paper are switched. Also, the signal (c
) is also transmitted to the film rotation device (74), and the film is rotated by 90°. Configuring it as follows: With this configuration, even if the shooting mode is set to specify a portrait screen when shooting, it will be possible to accurately meter only the area that will be printed.

When the magnification switching of the photometric zoom lens (M+,...) by the photometric zoom reflex control device (61) is completed, the completion is indicated (No. 7 (d) indicates the exposure by the exposure calculation circuit (6G). The second exposure calculation involves a photometry circuit (68) that receives light from the frame at the print position via a photometry zoom lens (ML).
The color balance and exposure amount are calculated based on the output of the frame. The color balance information expressed here is transmitted as a signal (c) to the filter control device (70) and used for color balance adjustment, and the exposure amount information is transmitted as a signal (') to the lamp control device (70). The signal (8) indicating the end of photometry is also transmitted from the exposure calculation circuit (66) to the lamp control circuit (50). The signal is transmitted and the lamp (LA) is temporarily turned off.

Next, the filter control device (70) is the photometric circuit (68)
Color filter (CF) according to color balance information from
When the seventh step is completed, the filter control a device (70) sends a signal (1
1) will be shown.

This signal (11) is connected to a lamp control circuit (50), a shutter control device f which controls the opening of a shank (ps) disposed at the end of the photographic paper (pp) at the printing position.
f (72).

Immediately after the signal (11) is input, the shunter control device (72) starts opening the shutter (ps), and the lamp control device (50) starts to open the shutter (ps) immediately after the signal (11) is input. After a certain period of time for the PS) to fully open, the lamp (LA) is turned on to print.The lighting time and light intensity of the lamp (LA) are adjusted according to the exposure amount information. It is configured to be controlled by a lamp control circuit (50).

Then, when printing by the lamp (LA) is finished,
The lamp control circuit (50) outputs an exposure completion signal (i) after turning off the lamp (LA). In response to this exposure completion signal (j), the film rotation device (52) starts feeding the film, and also starts the shutter control device (72).
) makes Nyanota (ps) leap. Furthermore, when the film rotating device (74) rotates the film 90° to print a frame designated with the R trimming mode, it rotates the film 90° in the opposite direction to return it to its original state.

Furthermore, this exposure completion signal (j) causes the photographic paper transport VC to
The printer (80) feeds the photographic paper (PP) to the right in the figure in preparation for the next print. Also, this exposure completion signal (j
), the screen edge detection device (56), the wart number reading device (58), the exposure calculation circuit (66), and the filter control device (70) are reset and prepared for the next printing. Then, the printed photographic paper is sequentially stored in a photographic paper storage device (not shown). In this manner, in the automatic printer according to this embodiment, appropriate printing is automatically performed according to the designated photographing mode.

(Left below) 1 nephew! As described in detail above, the present invention includes a mode selection means for selecting between a normal shooting mode and a trimming mode in which the area to be printed is narrower than the normal shooting mode, and when the trimming mode is selected, the normal 4Q shadow mode is selected. The film is characterized in that it has a trimming instruction means for storing in the film a signal instructing to print a vertically long range for a horizontally long print in the case of a horizontally long print. By specifying , you can easily obtain portrait prints without changing the camera's position. I don't have to worry about it.
