Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with a self-timer and / or a remote control receiving function, and more particularly, to a multi-point camera which selects a distance measuring point from a plurality of distance measuring points and displays the distance measuring result. The present invention relates to a camera having a distance measuring function.

[0002]

2. Description of the Related Art Conventionally, photography using a self-timer has been widely performed. This is to set a self-timer state in which a self-timer is used prior to taking a picture and then operate a release button of the camera to perform a picture taking operation after a predetermined time. A technique proposed in recent years, for example, Japanese Patent Laid-Open No. 2001-1748
No. 92 publication proposes a distance measuring point selecting device in a multi-point distance measuring area, in which a distance measuring area selecting device is arranged in proximity to a release button, and this selecting device also serves as a release button. It is a thing.

Further, for example, the photographer himself / herself takes a subject (person,
The photographer 2 operates the camera 3 fixed to the tripod 4 to operate the camera 3 fixed on the tripod 4 as shown in FIG. There are usually many situations in which one is trying to enter. For that purpose, first, the viewfinder screen observed by the photographer 2 with the camera 3 is made to have a composition as shown in FIG. 8B, for example. Then, the photographer 2 looks into the viewfinder of the camera 3 and adjusts the distance measurement points in advance for the subject at a finite distance. After that, by activating the self-timer and arranging at the location shown by the dotted line in FIG. 8B, a photograph in which the subject is in focus as shown in FIG. 8C can be easily taken.

[0004]

Next, as shown in FIG. 9A, there is no target finite subject (for example, in the case of a subject at infinity such as a landscape), and the photographer 2 takes a picture screen. Imagine a situation where you are trying to get inside. For example, this is a viewfinder screen as shown in FIG. In this case as well, the photographer 2 images the position where he / she appears in the form of the dotted line when determining the composition, and adjusts it to the target distance measuring point.

However, in the prior art, no specific example is described in the case of shooting in the remote control mode or the self mode using the remote control terminal (remote controller) 3, and the target (distance measuring point) can be confirmed. I cannot do it from the front of the camera. Therefore, as shown in FIG. 9C, no one has confirmed the moment of photographing with the finder, and therefore the photographer (that is, the subject) 2 cannot judge whether or not a photograph can be taken with a desired composition. Therefore, it often results in a failure photograph as shown in FIGS. 9 (d) and 9 (e).

The present invention has been made in view of the above problems, and an object of the present invention is to provide a camera which can roughly adjust the position of a subject when the photographer himself / herself becomes a subject in the self mode or the remote control mode. There is.

[0007]

In order to solve the above problems and achieve the object, the present invention takes the following means. Therefore, the camera of the present invention is a camera having a multi-point (multi-point) distance measuring function, and has means for selecting a desired distance measuring point and means for displaying the distance measuring result at the selected distance measuring point. However, the arrangement of each component is devised so that the distance measurement result can be easily recognized from the subject side.

That is, according to the first aspect, the distance measuring means having a plurality of distance measuring points and the distance measuring point selecting means for selecting a desired distance measuring point from the plurality of distance measuring points are mounted. In this camera, it is proposed that the display means for displaying the distance measurement result at the selected distance measurement point is arranged in front of the camera.

According to the second aspect, the distance measuring means having a plurality of distance measuring points, the display means for displaying the distance measuring result at the selected distance measuring point, and the self mode for switching between the self timer mode and the normal photographing mode. A camera including a switching means, wherein the display means operates when the self-timer mode is selected and the distance measurement result at the distance measurement point is a distance longer than a predetermined distance. To propose.

According to the third aspect, the distance measuring means having a plurality of distance measuring points, the distance measuring point selecting means for selecting a desired distance measuring point from the plurality of distance measuring points, and the remote control receiving means. We propose a camera that does not receive a remote control signal when the distance measurement result at a selected distance measurement point is longer than a predetermined distance.

[0011]

Next, referring to FIG. 3B, the distance measuring device 6 will be specifically described. For example, the distance measuring sensor 202 (C) at the distance measuring point at the center C is the distance measuring light receiving lens 2
The light projecting lens 20 that is arranged behind 03 and forms a pair.
Infrared light emitting diode (iRED) projected through 4
The reflected light of the 205 (C) light from the subject 300 is received. The light receiving lens 203 and the light projecting lens 204 are separated by the distance between the principal points of these two lenses (base line length s).

Here, when the focal length of the light receiving lens 203 (that is, the distance from the light receiving lens principal point to the distance measuring sensor) is represented by fj, the infrared signal light reflected and returned from the subject at a distance L is returned. , The light is incident on the sensor at a position separated by x with respect to the optical axis of the light receiving lens 203. Therefore, the relationship between the distance L and the incident position x on the sensor can be expressed by the following formula from the principle of triangulation. L = (s × fj) / x (Equation 1).

The distance measuring sensor 202 (C) is an optical position detecting element (PS) which is an element for detecting the incident position of the infrared signal light.
D) is used. Normally, in addition to the projected light (signal light) returned from the subject to the distance measuring sensor 202, steady light (steady light) illuminating the subject 300 also enters, so the distance measuring sensor 202 If the circuit connected to (C) does not remove this stationary light component, the correct signal light position x
Is not required.

The distance measuring sensor 202 (C) is a photoelectric conversion element having a predetermined resistance layer, and outputs two current signals which change according to the incident position and the incident light amount. As described above, this includes the stationary light component in addition to the signal light, so
The output of the distance measuring sensor 202 (C) is the Nch steady light removing circuit 206 and the Fch steady light removing circuit 20 that remove the steady light component.
Connected to 7.

This Nch stationary light removal circuit 206 (Fch
In the stationary light removing circuit 207, the output signal of the preamplifier 208 for current amplification is supplied to the compression circuit 209 including a compression diode, and the hold amplifier 210 adjusts the output level so that the compression voltage becomes a constant value. However, it is a circuit for controlling the base potential of the transistor 211.

By such feedback control, a current flows in the transistor 211 by the amount of the stationary light. Therefore, since the emitter resistance 212 is connected between the emitter of the transistor 211 and the ground, when the voltage of the emitter resistance 212 and the emitter connection point (position M) is monitored by the AD conversion circuit 216, it is constantly measured. The amount of light incident on the distance sensor 202 (C), that is, the amount of stationary light can be measured. This result is CPU
Input to 1.

In the distance measuring device 6 shown in FIG. 3B, the infrared light emitting diode 205 (C) as a light projecting element is controlled to emit light by the timing circuit 213 and the light projecting control driver 217, and at the same time the hold amplifier 210 is operated. Its function is OF
The signal photocurrent, which is signal-amplified by the preamplifier 208, is input to the compression circuit 209. The above has described the case of one of the two outputs of the distance measuring sensor 202, but the configuration and output method of the other (Fch stationary light removal circuit 207) are also the same as those described above.

The signals (iN, iF) from the two electrodes are
It is input to the ratio calculation circuit 215 through the above circuits. The ratio calculation circuit 215 calculates the difference between the two signal lights and inputs the result to the CPU 1. The signal current at position x is
It can be expressed by the following relational expression. x∝iN / (iN + iF) (Equation 2).

Therefore, if the result of iN / (iN + iF) is input to the CPU, x can be obtained and the subject distance L can be obtained from (Equation 1). In addition to the above, in this range finder, two sets of light receiving elements (202
(L, R)) and the light projecting element (205 (L, R)) are combined, and the timing circuit 213 is instructed by the instruction from the CPU 1.
Each is controlled by. The obtained distance measurement result is
Left (L), center (C), right (R) in that order, Lh,
Represented as Lc, Lm, etc.

FIG. 4 is a flow chart showing the camera sequence, and the photographing operation procedure of the camera in the first embodiment will be described. First, in step S1, it is determined whether or not the 1st. Release switch is ON / OFF (S1). When it is determined that it is ON (the 1st. Release button is pressed), the process proceeds to the next step S2, and OF
If it is determined that F (1st. Release button is not pressed), this step S1 is repeated.

In steps S2 to S4, photometry is performed using the photometry device 5 (S2), the distance measuring points are read, and the distance measurement is performed at the distance measuring points desired by the photographer (S3). Distance measurement is performed using the device 6 (S4). In step S5, it is determined whether the 2nd release switch is ON or OFF (S5). If it is determined to be ON (the 2nd release button has been pressed), the process proceeds to the next step S6, and OFF (the 2nd release button has not been pressed).
If it is determined that this step S5 is repeated.

In step S6, the status information of the self-SW is read (S6), and in step S7, the following branch judgment is made based on the status information (S7). That is, when the self SW is OFF (normal shooting mode), the process branches to step S13. When the self-SW is ON (self-shooting mode), the process proceeds to the next step S8. In step S8, distance measurement is performed using the distance measuring device 6 at the distance measurement point designated in step S3 (S8).

Here, in step S9, the above step S
The distance measurement result (LDATA) obtained in 8 is displayed. Photographer
The (subject) will confirm the position of the photographer himself based on the distance measurement result (LDATA) (S9). In step S10, the distance measurement result (LD
ATA) is compared with a predetermined distance stored in the EEPROM 26 mounted on the camera (S10). If the distance is longer than the predetermined distance, the above step S8 is performed.
Return to and re-range and display. When the distance is shorter than the predetermined distance, the process proceeds to step S11. In step S11, the operation of the self-timer starts and the self-LED starts blinking (S11). In step S12, the time from the start of the self-operation is counted and compared with a predetermined time (S
12). If it is shorter than the predetermined time, this step S12
Is repeated again. When the predetermined time has elapsed, the blinking of the self LED is stopped and the process proceeds to the next step S13.

In steps S13 to S15, focusing is first performed based on the current zoom position obtained from the output of the zoom position detection circuit 13 and the distance measurement result (LDATA) obtained in step S4 or step S8. The LD motor of the lens (LD) is driven (S13). Next, the shutter drive circuit 10 controls a known shutter mechanism to perform exposure (S14). Then, the feeding motor drive circuit 12 is driven to wind up one frame, and a series of photographing operations is completed (S15). Then, in preparation for the next shooting, the process returns to step S1 and the same sequence is repeated again.

As described above, in the first embodiment, the distance measurement result display means (that is, the distance measurement result display device 114) for displaying the distance measurement result is mounted on the front surface of the camera, so that the distance measurement desired by the photographer is performed. Since the distance measurement result at the point can be notified to the subject, the distance measurement result display device can determine whether or not the subject position at the time of shooting is approximately correct even in a shooting scene in which the photographer himself / herself becomes the subject. It can be recognized by looking at 114, and its position can be correctly determined.

(Modification 1) The above-described first embodiment may be modified as follows. For example, in the first embodiment,

(RMSW) 31 is added. Therefore, if this RMSW 31 is turned on to switch to the remote control mode, remote operation can be performed using a wireless remote control terminal (not shown) (hereinafter referred to as "remote control").

Next, the photographing operation procedure in the second embodiment will be described with reference to the flowchart showing the camera sequence in FIG. In step S201, it is determined whether or not the 1st. Release switch is turned on (S20).
1). If it is determined to be ON (the 1st. Release button is pressed), the process proceeds to the next step S202, and if it is determined to be OFF (the 1st. Release button is not pressed), this step S201 is repeated.

In steps S202 to S203,
First, photometry is performed using the photometric device 5 (S202). After that, the distance measuring points are read, and the distance measuring is performed at the distance measuring points desired by the photographer (S203).
Distance measurement is performed using the distance measuring device 6 (S204).

In step S205, it is determined whether the second release switch is ON (S205). ON
If it is determined that the 2nd release button has been pressed, the process proceeds to the next step S206, and if it is determined to be OFF (the 2nd release button has not been pressed), this step S2
Repeat 05.

From step S206, the state information of the remote control mode switch 31 (hereinafter abbreviated as "remote control SW") is first read (S206), the state of this remote control SW is determined (S207), and the remote control SW is turned off (normal photographing). Mode), the process proceeds to step S214. When the remote control SW is ON (remote control shooting mode), the process proceeds to the next step S208 to turn off the remote control receiving circuit (S208).

In step S209, distance measurement is performed using this distance measuring device (S209). In step S210, the distance measurement result obtained in step S209 is displayed and output to the distance measurement result display device provided on the front surface of the camera (S2).
10). The photographer (subject) will confirm the position of himself / herself on the composition based on the distance measurement result.

In step S211, the above step S2
The distance measurement result obtained in step 09 is compared with the predetermined distance data stored in the EEPROM (S211). As a result, when the distance is shorter than the predetermined distance data, the process proceeds to the next step S212. If the distance is longer than the predetermined distance data, the process returns to step S209 to perform re-ranging. In step S212, the CPU 1 turns on the remote control signal receiving circuit (S212). The remote control signal may not be received when the distance measurement result at the selected distance measurement point is longer than the predetermined distance.

In steps S213 to S215,
First, it is determined whether or not a remote control signal is received (S21
3) If received, the LD motor drive amount is determined from the distance measurement data obtained in step S209 or step S203 and the current zoom position, and the LD motor is driven (S214). Then, the shutter is controlled to perform exposure (S215), and one frame is wound up (S215).
216), and a series of shooting operations ends. After that, the process returns to step S201 to prepare for the next shooting, and the same sequence is repeated again.

As described above, in the second embodiment, the distance measurement result display means for displaying the distance measurement result is mounted on the front surface of the camera to notify the subject of the distance measurement result at the distance measurement point desired by the photographer. Therefore, even if the photographer himself / herself is the subject, it is possible to judge whether or not the subject position at the time of shooting is approximately correct. Furthermore, even if the remote control can be used, if it is determined that the subject position at the time of shooting does not meet the predetermined conditions, the remote control signal is not accepted, and the exposure operation when the subject position is incorrect Can be prevented.

(Modification 2) The above-described second embodiment can be modified as follows, and an effect equivalent to that of the second embodiment can be expected. In the above-described embodiment, the display device for displaying the distance measurement result is separately provided, but the self-LED used in the above-described first embodiment may be used, for example. Further, for example, in the flowchart of FIG. 7, the distance measurement result is displayed in step S210, but instead of displaying the distance measurement result, the blinking cycle of the self LED may be changed to notify the subject. Alternatively, at the same time, it may be notified that the remote control signal is not received.

(Other Modifications) First Embodiment and Second Embodiment
The embodiment may be modified in other ways. For example, in each of the above-described embodiments, the distance measurement result and the EEPR are obtained during the self operation.
I am comparing with the predetermined distance stored in the OM,
A switching means for switching the predetermined distance may be separately mounted. In this case, the photographer (ie, the subject himself) inputs the distance from the camera to the subject, so that the subject position of the photographer can be adjusted more accurately. Further, the case where the number of distance measuring points is 3 has been described, but it goes without saying that the same operation can be performed even when there are four or more distance measuring points.
