Abstract

PROBLEM TO BE SOLVED: To predict whether or not strobe light emission is performed before photographing and to execute photographing considering a photographing state by controlling the actuation of a light emitting means so that whether or not the strobe light emission is performed may be distinguishably expressed by the difference of the emitted light color of the light emitting means. SOLUTION: When a low-speed synchro mode, a bulb synchro mode or a daylight synchro mode being an exposure mode in which a stroboscope emits light is selected or a first or a second automatic mode is selected and a CPU discriminates that it is necessary to drive a strobe light emission part 5, whether or not charge required for the strobe light emission of the part 5 is completed is discriminated. When an answer is YES, a red light emitting diode RD is continuously lit. Meanwhile, when a bulb mode or a low-speed shutter mode being an exposure mode in which the stroboscope does not emit the light is selected or the first or the second automatic mode is selected and the CPU discriminates that it is unnecessary to drive the part 5, a green light emitting diode GD is continuously lit.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a camera.

[0002]

2. Description of the Related Art A camera equipped with a strobe device (strobe) is known. For example, this camera has an auto mode in which the strobe emits light (drive) automatically in dark places or backlight, a daylight sync mode in which the strobe emits light regardless of the light place or dark place, and a forced suppression of strobe light emission. A plurality of exposure modes such as a low-speed shutter mode are provided, and a photographer (user) selects a desired exposure mode from among the plurality of exposure modes to take an image.

An exposure mode is selected by rotating a rotary dial called an "exposure selection dial". Specifically, illustrations and characters indicating the respective exposure modes are drawn on the exposure selection dial along the circumferential direction of the upper surface of the dial. A desired exposure mode is selected by matching illustrations and characters corresponding to the exposure mode with the index.

Further, a light emitting diode for emitting light of a predetermined color (one color) is provided below the exposure selection dial corresponding to the index position of the camera body.

[0005] A central control circuit (CPU) provided in the camera body controls lighting of the light emitting diode when an exposure mode is selected by a photographer.

[0006] The photographer recognizes the currently selected exposure mode based on the illustrations and characters displayed by the light emitting diodes.

For example, a desired print image such as a print image with an aspect ratio of 3: 4, a print image on a wide screen, or a print image on a landscape screen (panorama screen) can be obtained.

On the right side of the upper surface of the camera in FIGS. 1 and 2 (on the left hand side when the photographer looks through the finder of the APS camera 100), a strobe light emitting section 5 is provided.

When the main switch (power switch) is off (non-shooting), the strobe light emitting section 5 is housed in the camera body and protected by the strobe cover 6. When the switch is turned on (at the time of photographing), it takes a posture protruding from the camera body as shown in FIG. 1 in order to allow the subject to be irradiated with strobe light. Then, when the main switch is turned off, the strobe light emitting unit 5 is stored again in the camera body.

A protector 7 is provided on the front of the camera. The protector 7 is provided to cover the lens 8 during non-photographing, thereby protecting the lens 8 from external dust and impact.

As shown in FIG. 1, an embossed portion 7a formed by embossing is provided below the protector 7.

FIG. 2 shows a state in which the protector 7 is closed and not photographing. When photographing is performed, the photographer puts a finger on the embossed portion 7a and puts the protector 7 on. Slide in the direction of arrow A (opening direction) shown in FIG.

Is provided. The exposure mode selection signal (information about the exposure mode) formed by the code plate 22 and the connection piece 23 is transmitted to the central control circuit (CP) in the camera body via the first flexible substrate 24.
U) (control means).

At the center of the exposure selection dial 1, a shutter button 2 having a substantially T-shaped cross section is provided. The shutter button 2 is urged by an elastic member 25 such as a spring so that the operation surface 2a is positioned on the same plane as the exposure selection dial 1 when not pressed.

A shutter switch 26 is provided on the first flexible board 24. The shutter switch 26 includes a contact 262 and a cover for covering the contact.
And an elastic body 261 having conductivity such as a spring.

During photographing, the photographer presses the shutter button 2 against the urging force of the elastic member 25. When the shutter button 2 is pressed in the first step, the photographer presses the shutter button 2. The bottom surface (the bottom surface of the rod-shaped portion having a substantially T-shaped cross section) is the elastic body 26 of the shutter switch 26.
Touch 1. That is, the first stage of the shutter switch 26 is turned on.

When the shutter button 2 is pressed in the second step, the shutter button 2 is pressed down integrally with the elastic body 261 in contact with the bottom surface, and the elastic body 261 is elastically deformed. The lower surface contacts the contact 262. That is, the second stage of the shutter switch 26 is turned on. Using this as a trigger, the CPU performs predetermined photographing control such as iris opening control and film winding.

On the lower side of the exposure selection dial 1 in FIG. 3, a red light emitting diode (LED) RD and a green light emitting diode (LED) GD are arranged side by side. Each of the light emitting diodes RD and GD is provided with an exposure selection dial 1 respectively.
3, that is, between the shutter button 2 and the index 3.

Each of the light emitting diodes RD and GD is connected to the CPU through a second flexible substrate 28, respectively.
Is connected to As will be described later, the CPU determines the actual shooting state based on the information on the exposure mode selected by the exposure selection dial 1 and the amount of light (photometric information) measured by the light receiving unit 10 and performs each of the light emission. The operation (light emission) of the diodes RD and GD is controlled.

The exposure selection dial 1 is provided with a hole 27 for guiding the light emitted by each of the light emitting diodes RD and GD to the back side of the dial 21. The hole 27 is emitted by each of the light emitting diodes RD and GD. The illustration and the characters are illuminated and displayed by irradiating the illustration and the characters from the back side of the dial 21 through the holes 27.

The red light emitting diode RD and the green light emitting diode GD constitute light emitting means.

In the present invention, the hole 27 is formed, for example, by
You may change to the window part formed with the member which has light transmittance.

The APS camera 100 has a total of seven exposure modes: a first auto mode, a second auto mode, a low speed sync mode, a bulb sync mode, a bulb mode, a daytime sync mode, and a low speed shutter mode. As described above, a desired exposure mode can be selected from these exposure modes by using the exposure selection dial 1.

As shown in FIG. 2, the dial 21 of the exposure selection dial 1 has "AUT" indicating the first auto mode.
"O" and "AUT" representing the second auto mode.
"O" and an illustration of the human eye, an illustration of a person and the moon indicating the low-speed sync mode, an "B" and an illustration of the zigzag arrow indicating the valve sync mode, and "B" indicating the valve mode. Characters and
An illustration of a zigzag arrow indicating the daytime sync mode and an illustration of a prohibition mark indicating the low-speed shutter mode with the zigzag arrow superimposed thereon are drawn along the circumferential direction of the dial 21.

The first and second auto modes are respectively
This is an exposure mode selected when the strobe light-emitting unit 5 automatically emits light in a dark place or in backlight.

In the first and second auto modes, photometry is performed at the time of photographing, and it is determined whether or not to drive (flash) the strobe light emitting unit 5 based on the result.

Therefore, when the first and second auto modes are selected, the actual shooting conditions are as follows.
There are a first photographing state in which photographing is performed by driving the strobe light emitting unit 5, and a second photographing state in which photographing is performed without driving the strobe light emitting unit 5.

In the second auto mode, main emission is performed immediately after the pre-emission, and so-called "red-eye", in which red light is reflected by blood vessels in the eyeball by flash emission photography and the pupil is reproduced red, is prevented. (Red-eye reduction function).

On the other hand, in the first auto mode, the red-eye reduction function does not work.

Therefore, the second auto mode is selected when performing imaging using the red-eye reduction function, and the first auto mode is selected when performing imaging without using the red-eye reduction function.

The low-speed sync mode is, for example, an exposure mode that is selected when photographing a person with a sunset in the background.
By driving the strobe light emitting unit 5 and irradiating the person with the light from the strobe light emitting unit 5, the mode is a mode in which the evening scene and the person can be photographed in a well-balanced manner. In the low-speed sync mode, the red-eye reduction function operates.

The valve synchro mode is an exposure mode in which the shutter is kept open while the shutter button 2 is being pressed, and the strobe light emitting unit 5 is driven in synchronization with the pressing operation of the shutter button 2. In the valve synchro mode, the red-eye reduction function works.

The valve mode is an exposure mode in which the shutter is kept open while the shutter button 2 is being pressed, and the strobe light emitting unit 5 is not driven.

The daytime synchro mode is an exposure mode in which the strobe light emitting unit 5 is driven regardless of the brightness of the photographing place. For example, when a person wearing a hat becomes dark except for backlighting, such as when photographing a person wearing a hat. This is the exposure mode to be selected when it is lost.

On the other hand, the low-speed shutter mode is an exposure mode in which the strobe light-emitting unit 5 is not driven even in a dark place. This is the exposure mode to be selected when you want to perform.

Next, the operation and circuit configuration of the APS camera 100 will be described. FIG. 5 shows a red light emitting diode RD and a green light emitting diode GD of the APS camera 100.
6 is a flowchart showing the drive control operation of the first embodiment. Hereinafter, description will be made based on this flowchart.

The APS camera 100, as described above,
When the protector 7 shown in FIG. 1 is slid in the direction of the arrow A (opening direction), the main switch is turned on. When the main switch is turned on, the strobe light emitting unit 5 is charged to the battery power. At the same time, the flowchart shown in FIG. 5 starts and proceeds to step S1.

After or before the slide operation of the protector 7, the photographer selects the desired exposure mode by rotating the exposure selection dial 1 to set a desired illustration or character to the position of the index 3. However, in step S1, the CPU detects the selected exposure mode. The CPU detects the exposure mode based on the exposure mode selection signal (information on the exposure mode) formed by the code plate 22 and the connection piece 23 shown in FIG. Next, the process proceeds to step S2.

In step S2, the CPU determines whether or not the selected exposure mode is an exposure mode in which the strobe does not emit light (an exposure mode in which photographing is performed without driving the strobe).

More specifically, in the case of the APS camera 100, a bulb mode and a low-speed shutter mode are provided as exposure modes that do not emit a flash, and when the exposure mode that does not emit a flash is selected, that is, If the determination is YES, the process proceeds to step S13, and if the exposure mode in which the flash is not emitted is not selected, that is, if the determination is NO, the process proceeds to step S3.

In step S3, the CPU determines whether the selected exposure mode is the first auto mode or the second auto mode. If YES, the process proceeds to step S4, and if NO, the process proceeds to step S4. Proceed to S6.

In step S4, the photometric switch is turned on. Thereby, photometry is performed via the light receiving unit 10, and thereafter, the process proceeds to step S5.

In step S5, as a result of the photometry performed through the light receiving unit 10, the CPU determines whether or not it is necessary to drive the strobe light emitting unit 5 (light emission of the strobe). If YES, the process proceeds to step S6. Proceed, if no, step S
Proceed to 13.

Step S6 is the same as step S3.
When the PU is determined to be NO, that is, when a low-speed sync mode, a bulb sync mode, or a daylight sync mode, which is an exposure mode that emits a flash (an exposure mode in which the flash is driven to perform shooting), is selected, or , The first auto mode or the second auto mode has been selected, and the step proceeds when the CPU determines in step S5 that the strobe light emitting unit 5 needs to be driven.

In step S6, the CPU determines whether or not the charging necessary for the flash emission of the flash emission unit 5 has been completed (the charging state of the flash emission unit 5). If the charging is not completed, the process proceeds to step S8, and if YES, that is, if the charging required for strobe light emission is completed, the process proceeds to step S7.

When the CPU proceeds to step S7, the CPU continuously lights the red light emitting diode RD (continuously emits light).
And the process proceeds to step S9.

By turning on the red light emitting diode RD, the photographer is in the first photographing state in which photographing is performed by driving the strobe before (prior to) photographing (the strobe is driven during photographing). And that the charging required for strobe light emission has been completed can be easily and reliably grasped.

When the CPU proceeds to step S8,
The red light emitting diode RD is intermittently turned on (intermittently emits light), that is, blinks, and the process proceeds to step S9.

The photographer, by the blinking of the red light emitting diode RD, is in the first photographing state in which the photographing is performed by driving the strobe before photographing, and the charge necessary for the strobe light emission is not completed. Can be grasped easily and reliably.

On the other hand, in step S13, if the CPU determines YES in step S2, that is, the bulb mode or the low-speed shutter mode, which is the exposure mode in which the strobe is not fired (exposure mode in which photographing is performed without driving the strobe), is selected. Is performed, or when the first auto mode or the second auto mode is selected, and the CPU determines in step S5 that the driving of the strobe light emitting unit 5 is unnecessary, the process proceeds to the next step.

When the CPU proceeds to step S13,
The green light emitting diode GD is continuously turned on (continuously emits light), and the process proceeds to step S9.

By turning on the green light emitting diode GD, the photographer can easily be in the second photographing state in which photographing is performed without driving the strobe before photographing, that is, the strobe is not driven during photographing. And it can be grasped reliably.

Here, lighting control of the red light emitting diode RD and the green light emitting diode GD will be described.

FIG. 4 is a circuit diagram showing a configuration example of a lighting drive system for the red light emitting diode RD and the green light emitting diode GD.

As shown in the figure, the red light emitting diode R
The D light emitting diode GD and the green light emitting diode GD each have an anode connected to the anode of the power supply 40 and a cathode connected to the IC switch 41 connected to the cathode of the power supply 40 via the resistors R1 and R2. I have.

The IC switch 41 is controlled to be switched by a CPU 42.
Controls the switching of the IC switch 41 to the red light emitting diode RD in step S7, and controls the switching of the IC switch 41 to the green light emitting diode GD in step S13. Thus, in step S7, the red light emitting diode RD is turned on through the IC switch 41 to emit red light, and in step S13, the green light emitting diode GD is turned on through the IC switch 41. Green light is emitted.

The red light and the green light emitted by the light emitting diodes RD and GD are applied to the back side of the dial 21 of the exposure selection dial 1 through the hole 27 shown in FIG.
As a result, red or green light is emitted outside the camera body via a predetermined exposure mode display portion of the exposure selection dial 1, that is, predetermined illustrations and characters drawn on the dial 21 of the exposure selection dial 1. , The illustration or character is displayed in red or green.

In step S8, the CPU 42
Controls the IC switch 41 to switch to the red light emitting diode RD side so that the red light emitting diode RD emits light intermittently.

As described above, after executing step S7, step S8 or step S13, step S9
Proceed to.

In step S9, the CPU determines whether or not the photographer has rotated the exposure selection dial 1 to select a new exposure mode. If YES, the process proceeds to step S10.

In step S10, the red light emitting diode R
D and the green light emitting diode GD are turned off, and thereafter, the process returns to step S1, and the above-described routines after step S1 are repeatedly executed. Thus, in the exposure mode newly selected by the photographer, the lighting control of the red light emitting diode RD or the green light emitting diode GD is performed. If NO is determined in the step S9, the process proceeds to a step S11.

In step S11, the CPU determines whether or not the protector 7 shown in FIG. 1 has been slid in the direction of arrow B (closing direction) to turn off the main switch.

If NO in step S11, the process returns to step S9, and repeats the above-described routines until the main switch is turned off. If YES, the process proceeds to step S12.

In step S12, the red light emitting diode RD and the green light emitting diode GD are turned off.

The turning off of the red light emitting diode RD and the green light emitting diode GD is controlled by the CPU 4 shown in FIG.
2 is performed by controlling the IC switch 41 to be in the neutral state, and turning off the red light emitting diode RD or the green light emitting diode GD that is in the conductive state.

With the above, all the routines shown in the flowchart of FIG. 5 are completed. As described above, according to the APS camera 100, the illustration and characters of the exposure selection dial 1 corresponding to the exposure mode selected by the photographer are illuminated and displayed, so that the exposure mode selected by the photographer is photographed. People can be clearly recognized.

In the APS camera 100, when the actual (current) photographing state is the first photographing state in which strobe light emission is performed at the time of photographing, red light is used, and strobe light emission is performed at the time of photographing. When there is no second shooting state, the illustration and the characters of the exposure selection dial 1 corresponding to the exposure mode selected by the photographer are illuminated and displayed in green light.

The photographer can predict or recognize the actual photographing state (the presence or absence of strobe light emission at the time of photographing) before photographing due to the difference in the emission colors, and perform photographing in consideration of this photographing state. It can be carried out.

For example, by notifying the person to be photographed that flash light is emitted before photographing, the person to be photographed can be prepared for the strobe light emission, thereby closing the eyes. Inconveniences such as photographing can be prevented.

In the APS camera 100, when the actual photographing state is the first photographing state in which strobe light emission is performed at the time of photographing, if the charging required for strobe light emission is completed, red light emission is performed. The diode RD lights continuously,
If the charging necessary for strobe light emission is not completed, the red light emitting diode RD is intermittently lit, so that the photographer can easily and reliably determine whether or not the charging has been completed before shooting. Can be grasped.

Also, in the APS camera 100, the same light emitting means displays the exposure mode selected by the photographer and the presence or absence of strobe light emission.
The display of the exposure mode and the display of the presence / absence of strobe light emission can be performed without increasing the number of parts.

Further, since the presence or absence of strobe light is distinguished by the difference in emission color, the photographer can recognize it very easily.

In the APS camera 100, when the photographer looks at one place, that is, the part indicated by the index 3 on the dial 21 of the exposure selection dial 1, at the same time, the photographer selects the exposure mode selected by the photographer. The presence or absence of strobe light can be recognized.

Next, a second embodiment of the camera of the present invention will be described. FIG. 6 shows a second embodiment in which the camera of the present invention is applied to an APS camera, and is a cross-sectional view taken along line DD in FIG.

As shown in FIG. 6, in the APS camera 100 of the second embodiment, a red light emitting diode RD and a green light emitting diode GD are provided below the index 3 in FIG.

The indicator 3 is formed of a member having light transmittance. At the lower side of the indicator 3 in FIG. 6, a hole 30 for guiding the light emitted by each of the light emitting diodes RD and GD to the back side of the indicator 3 is provided.

The light emitted by the red light emitting diode RD or the green light emitting diode GD is applied to the back side of the index 3 through the hole 30 and passes through the index 3. Thus, the indicator 3 emits red or green light.

The photographer must be in the first photographing state in which the strobe is driven and photographing is performed before photographing when the red light emitting diode RD is turned on and the indicator 3 emits red light.
That is, it is possible to easily and reliably grasp that the strobe is driven at the time of imaging.

[0105] The photographer has a green light emitting diode GD.
Lights up and the indicator 3 emits green light, so that it is easy and assured that the camera is in the second shooting state in which shooting is performed without driving the strobe before shooting, that is, the strobe is not driven during shooting. You can figure out.

In the present invention, the hole 30 is formed by, for example,
You may change to the window part formed with the member which has light transmittance.

Similarly to 0, the exposure mode selected by the photographer can be visually confirmed by the illustration and characters of the exposure selection dial 1 indicated by the index 3, and the photographer can determine the exposure mode by the difference in the emission color of the index 3. Before shooting, it is possible to predict or recognize the presence or absence of strobe light emission at the time of shooting, and to perform shooting in consideration of the presence or absence of strobe light emission.

For example, in the present invention, a light emitting diode of another color (for example, a blue light emitting diode, a yellow light emitting diode, etc.) may be provided instead of the red light emitting diode RD and the green light emitting diode GD.

Further, in the present invention, the light emitting means is not limited to the light emitting diode, but may be constituted by various light emitting elements such as an EL element.

Further, in the present invention, the light emitting means may be configured to emit light of three or more colors, and the three or more photographing states may be distinguished from each other by different emission colors.
