Detailed Description of the Invention

[0001]

[0002]

2. Description of the Related Art Conventionally, in a camera having a red-eye mitigation function and mode switching, the red-eye mitigation pre-emission light source is not turned on when the red-eye mitigation mode function is not used, and the second stroke switch of the release switch is used. When the SW2 is turned on, the shooting operation is started at the same time.

On the other hand, when the red-eye mitigation mode function is used, even if the first and second strokes of the release switch are turned on, the pre-light emission for red-eye mitigation is performed for a predetermined time required for the red-eye mitigation as a shooting preparation operation. The timing is such that the light source is turned on, the release operation is prohibited while the light source is turned on, and the photographing operation is performed after a predetermined lighting time has elapsed.

[0004]

However, in the above-described conventional example, when the red-eye reduction mode is selected, the red-eye reduction light source is turned on for a predetermined time required for red-eye reduction as a shooting preparation operation, and a predetermined time during which the light source is turned on. The shooting operation is prohibited only by turning on the red-eye reduction light source, and the camera is ready to shoot after a predetermined period of time, so it is possible to shoot when the battery is exhausted or the environment is low. The recycle time until the red-eye reduction light source is turned on is longer, and the recycle time required for shooting preparation when the red-eye reduction light source is turned on is longer because the red-eye reduction light source is turned on after the main capacitor is charged to a predetermined voltage. There was a drawback that a situation that would miss

Therefore, the object of the invention described in claim 1 is to:
Especially when the battery is extremely drained or when shooting in a low-temperature environment, the second shot during continuous shooting can achieve both the effect of red-eye reduction and the reduction of the time lag until release, which may miss a shutter chance. It is to provide a camera that improves operability.

Further, an object of the present invention as set forth in claim 2 is to similarly take continuous shots from the third shot to the nth shot when the battery is extremely consumed or when shooting is performed in a low temperature environment. In each shot, it is to provide a camera that improves the operability by achieving both the effect of red-eye reduction and shortening the time lag until release.

Further, an object of the present invention as set forth in claim 3 is to provide each of the third shot to the nth shot as long as continuous shooting is possible, when the battery is exhausted or shooting is performed in a low temperature environment. It is an object of the present invention to provide a camera that improves the operability by achieving both the effect of red-eye reduction and the shortening of the time lag until the release by a simplified control.

Further, the object of the invention described in claims 4 and 5 is that the recycle time after the second shot predicted during continuous shooting differs from the time when the actual charging completion voltage is reached, and an error occurs in the predicted value. Even in the case, it is to provide a camera that can continue shooting without any trouble.

According to this structure, each recycle time from the third shot to the nth shot predicted by the predictive calculation means is stored in the memory each time, and the predicted shot refers to the recycle time stored in the memory, and the red eye Lighting control can be performed at the timing when the light source is turned on for a predetermined time during the charging operation and turned off at the same time as the charging is completed.

If the exposure time is shorter than the time required to reach the charge completion voltage, the release operation is performed before the actual charge completion voltage is reached.

According to this structure, even if the predicted and stored recycle time deviates to a direction shorter than the time required to reach the actual charging completion voltage, if the exposure is sufficient, the red-eye is kept for a predetermined time in accordance with the predicted recycle time. Turn on the light source,

According to this structure, even if the predicted and stored recycle time deviates to a direction longer than the time at which the actual charge completion voltage is reached, the red eye light source is lit and turned off for a time shorter than a predetermined time and at the same time corrected. Release operation can be performed.

FIG. 2 is a flowchart of the operation of the camera shown in FIG.

Next, the operation will be described with reference to FIG. First, is it in red-eye reduction mode? , The state of the red-eye reduction mode switch 13 is detected (S101). If the red-eye mitigation mode switch 13 is in the on state, the red-eye mitigation mode is set, and the process proceeds to S102. If the switch 13 is in the off state, a known camera sequence for not performing the known red-eye mitigation function is performed.

Further, in the case of the red-eye reduction mode, is it the continuous shooting mode? The state of the continuous shooting mode switch 16 is detected (S102). If the continuous shooting mode switch 16 is in the on state, the continuous shooting mode is entered and the process proceeds to S103. If the switch 16 is in the off state, a known camera sequence in which the continuous shooting function is not performed.

Then, in the continuous shooting mode, is the first stroke switch SW1 (11) on? Is determined (S103). If SW1 is off, it will be in a standby state until it becomes an on signal, and if SW1 is on, S
Proceed to 104.

Next, the power supply voltage for confirming the camera operation is checked by the SW1 and the battery check voltage detection circuit 17 (S104). If the power supply voltage value is less than or equal to the predetermined voltage value, the voltage is checked again by SW1 and the battery check voltage detection circuit 17, and if the power supply voltage value is greater than or equal to the predetermined value, the process proceeds to S106 (S105).

The distance of the main subject is detected by the distance measuring circuit 6 (S106), and the brightness of the main subject is measured by the photometric circuit 7 (S107). Brightness is determined by comparing the brightness information obtained in S107 with a predetermined brightness (S108). If the brightness is equal to or higher than a predetermined brightness, the input of the second stroke switch SW2 is determined (S109), and if SW2 is turned on, the photographing operation is started (S133).

If the brightness is dark in the determination of S108, the strobe light emission mode is set and the main capacitor is charged (S1).
10). It is determined whether or not the main capacitor has been charged, and the main capacitor is charged until the charging is completed (S111). When charging is completed, it is determined whether or not the shutter release second stroke switch SW2 is turned on (S112). SW
If 2 is off, it will be in a standby state until it becomes an on signal,
When SW2 is turned on, the lamp 2 which is the light source for red-eye reduction
To turn on or blink the transistor 3 by making it conductive (S113). A timer is started in order to measure the lighting or blinking time of the light source required for red-eye reduction as a shooting preparation operation (S114). FIG. 3 is an explanatory diagram of the optimum lighting time of the red-eye light source lamp shown in FIG.

In FIG. 3, the main subject pupil diameter when the main subject looks at the lamp 2 after the lamp 2 of the light source for red-eye reduction is turned on or blinks is plotted on the vertical axis, and the lighting time of the lamp 2 is plotted on the horizontal axis. As is clear from FIG. 3, the optimum lighting time of the lamp 2 for producing the effect of red-eye reduction is T ₁ , and at this time, the pupil diameter of the main subject is H _MIN and the minimum. And the red-eye phenomenon will be alleviated. In the present embodiment, the lighting time T ₁ is set to “1.5 seconds” which is said to be most effective for red-eye reduction, but this lighting time timer setting can be arbitrarily changed by software or the like. Is.

Then, is it within 1.5 seconds after the lamp 2, which is the red-eye reduction light source, starts lighting or blinking? Judge,
If it is still less than 1.5 seconds, the light source lamp 2 maintains the lighting state until 1.5 seconds have elapsed (S114). When 1.5 seconds have passed, the control transistor 3 is turned off and the lamp 2 of the red-eye reducing light source is turned off (S115). Then, the photographing operation by the release switch SW2 is started (S11).
6).

Next, the continuous shooting operation of the first shot and the second shot in the continuous shooting mode using the red-eye reducing function of the camera sequence will be described in detail.

In the continuous shooting mode, first, the flash control circuit 4 charges the main capacitor, and at the time of charging, time counting for measuring the recycling time is started (S117).

The charging voltage of the main capacitor is set to A in the CPU 1.
A / E converter (not shown) or a passive element such as a Zener diode in the flash control circuit 4 is used to detect whether or not the charging completion voltage has been reached. If the charging completion voltage has not been reached, the voltage is boosted to reach the charging completion voltage, and if the charging completion voltage has been reached, the recycle time required to complete charging is measured by the clock circuit 14 (S118).

Based on the recycle time and the battery check voltage measured here, the CPU 1 performs a predictive calculation of the recycle time required for the next continuous shooting shot (second shot), and the calculation result is sent from the CPU 1 to the memory circuit 1.
5 and set "FLAG 1" to indicate that the recycling data has been set (S11).
9). It is determined whether or not the second stroke SW2 for shutter release is on (S120). If SW2 is off, it will be in a standby state until it is turned on, and if SW2 is on, the routine proceeds to S121.

Next, the lamp 2, which is the light source for red-eye reduction, is turned on or blinks by setting the transistor 3 in the conductive state (121). A timer is started to measure the lighting or blinking time of the light source required for red-eye reduction as a shooting preparation operation (S122). Lamp 2 which is a red-eye reduction light source
It is checked whether or not T1 = 1.5 seconds has elapsed since the start of lighting or blinking. If it is within 1.5 seconds, the red-eye light source lamp 2 maintains the lighting state until 1.5 seconds have elapsed. When 1.5 seconds have elapsed from the start of lighting, the control transistor 3 is turned off and the red-eye light source lamp 2 is turned off (S123).

At the same time, the second shot in the continuous shooting mode is prepared before the shutter release. First, the second shot recycle data predicted and stored in S119 is read with reference to FLAG1 (S124), and the battery check voltage detection circuit 17 checks the power supply voltage for camera operation confirmation (S125). Prepare to shoot the second shot. The battery check here is the same as the previous time, and if the power supply voltage is equal to or lower than the predetermined value, the voltage is checked again, and if the power supply voltage is equal to or higher than the predetermined value, the process proceeds to S128 (S128).
126). When it is determined that the preparation for the second shot is completed, the shooting operation for the first shot by the SW2 input is started and the shutter release is performed (S128).

Then, the second shot in the continuous shooting mode is entered. In synchronization with the shutter release of the first shot, the second
Charging of the main capacitor at the shot starts. During the charging operation, the lamp 2 which is the light source for red-eye reduction is turned on by the control transistor 3 1.5 seconds before the time to reach the charging completion voltage of the predicted recycling time (S12).
9). A timer is started to judge whether the lighting or blinking time of the red-eye light source lamp 2 has passed 1.5 seconds (S13
0), if T ₁ = 1.5 seconds has not elapsed, the lighting state is maintained until 1.5 seconds elapse, and when 1.5 seconds elapses, the control transistor 3 is turned off to reduce the red eye. The lamp 2 which is the light source is turned off (S131). The charging voltage of the main capacitor reaches the charging completion voltage by the flash control circuit 4 in synchronization with the lapse of the lighting time of 1.5 seconds, the shooting operation of the second shot in the continuous shooting mode is started, and the shutter release is performed ( S132).

First and second in such continuous shooting mode
Each timing of shots will be described in more detail with reference to FIGS. 4 and 5 below.

FIG. 4 is a timing chart showing the lighting timing of the red-eye light source lamp.

FIG. 5 is a timing chart of the recycle time and the lighting of the red-eye light source lamp. FIG. 4 shows the relationship between the ON timing of the release switch for each shot and the lighting timing of the light source lamp 2 in the continuous shooting mode. First, the release switch SW1 (11) is turned on, the red-eye light source lamp 2 is turned on 1.5 seconds before the exposure, and the red-eye light source lamp after the optimum time T ₁ = 1.5 seconds shown in FIG. 3 has elapsed. Release switch SW in synchronization with turning off 2
2 shows the timing at which the shutter release by 2 (12) is performed.

FIG. 5A shows the recycle time of the first shot main capacitor, the shutter release point, and the lighting timing of the red-eye light source lamp 2 in the red-eye reduction and continuous shooting modes. This corresponds to the operation of the first shot, and when the charging of the main capacitor starts, the charging time to the predetermined charging completion voltage value Vstop (9.5 seconds in this example) by the timing circuit 14 is synchronized with the start of charging. And release switch S
By inputting W2, the red-eye reduction light source lamp 2 is lit or blinked for 1.5 seconds, and then shutter release is performed.

Here, since it is assumed that the battery is significantly worn or used in a low temperature environment, the charging time is 9.5 seconds, and then the red-eye reduction light source is turned on or blinked for 1.5 seconds for recycling. The example shows that the time requires 11.0 seconds.

FIG. 5B also shows the recycle time of the second shot, the shutter release point and the lighting timing of the light source lamp 2, and the main capacitor of the second shot is charged in synchronization with the shutter release of the first shot. However, the CPU 1 calculates the recycle time of the second shot predicted and stored at the time of the first shot by FLA.
If it is referred to from G1, and the recycling time is 10 seconds, the time required to reach the predetermined charging completion voltage Vstop (1
0 seconds), the red-eye light source lamp 2 starts to turn on or blink 1.5 seconds before, and 1.5 seconds later, the charging voltage reaches a predetermined Vsto.
Upon reaching p, the light source lamp 2 for red-eye reduction is turned off, and the shutter release for the second shot is performed. Therefore, the recycling time of the second shot (10
Seconds) is 1 from the 11 second recycle time of the first shot.
It will be shortened in seconds.

Although the flowchart of FIG. 2 shows an example of continuous shooting of two images up to the second shot, the recycle time of the next third shot is predicted and calculated during the shooting operation of the second shot by the same procedure. And prepare to shoot, the third
Set the number of continuous shots to 3 or more so that the calculation of the recycle time of the next 4th shot is performed during the shooting operation of shots to proceed with the preparation for shooting, and the recycle time of the next shot is predicted one after another. If shooting preparation is performed, the n-th shot recycle time is predicted from the (n-1) -th shot recycle time.
It enables continuous shooting up to the shot.

As described above, in the example given in the first embodiment, the charging time of the main capacitor for the second shot is set to 10.0 seconds, which is 0.5 seconds longer than that of the first shot, but the second shot is recycled. As for the time, assuming that the lighting or blinking time of the red-eye reduction light source lamp 2 is the same as 1.5 seconds of the first shot, the time could be shortened to 10.0 seconds, so in the continuous shooting mode, the red-eye reduction effect and the time lag until release are reduced. Both shortening was achieved.

(Second Embodiment) Next, a second embodiment will be described.

In the first embodiment, in the red-eye reduction mode and the continuous shooting mode, the recycle time of the second shot is predicted and calculated from the recycle time of the first shot, and the predicted charging completion time is 1.5. A configuration is described in which the red-eye light source lamp 2 is turned on or blinks two seconds before, the red-eye light source lamp 2 is turned off in synchronization with the completion of charging, and the shutter is released. In addition, in addition to the third shot during the second shot, Predict resurrection time, that is, nth
The continuous shooting method of predicting the recycling time of the nth shot during one shot has been described.

The difference from the second embodiment is that in the red-eye reduction and continuous shooting modes, the recycle time of the nth shot is predicted from the recycle time of the immediately preceding shot, the (n-1) th shot. No, not first
From shot recycle time, 2nd shot to nth shot
This is the point that a calculation method for predicting and calculating all shot recycle times is used. Other than that, the basic configuration is the same as that of the first embodiment, and all the drawings in FIGS. 1 to 5 are also common, so the configuration of these drawings and the operation description of each drawing are omitted.

As described above, according to the second embodiment,
Since the prediction calculation process is simplified as compared with the first embodiment, the lighting control and continuous shooting control of the red-eye reduction light source can be simplified, and the processing time can be shortened, so that the efficiency can be improved.

(Third Embodiment) Next, a third embodiment will be described.

The third embodiment is a countermeasure when an error occurs between the predicted recycle time of the shot and the actual recycle time in the red-eye reduction and continuous shooting modes. Each of FIGS. 1 to 5 is common to the first embodiment.

When the actual recycle time does not reach the charge completion voltage with respect to the estimated recycle time, the lowest emission voltage of the xenon tube 5 in the flash control circuit 4 is sufficiently lower than the charge completion voltage. However, the correction processing in such a case will be described in more detail below.

FIG. 6 is a time chart of the recycling time of the camera according to the third embodiment of the present invention.

FIG. 6A shows an example in which the predicted recycling time is shorter than the actual recycling time. In this case, since the xenon tube 5 having a low minimum emission voltage is used, if the exposure is sufficient, the predicted recycling time remains unchanged. The red-eye light source lamp 2 is turned on 1.5 seconds before the end time and turned off after 1.5 seconds, and at the same time, shutter release is performed.

FIG. 6B shows an example in which the predicted recycling time is predicted to be longer than the actual recycling time. If the predicted value reaches the charging completion voltage Vstop as described above, T ₁ = 1.5 seconds. Is shortened to 1.3 seconds, and the red-eye light source lamp 2 is corrected so that the control transistor 3 is turned on / off by a control signal from the CPU 1 to turn on or blink.

As described above, in the third embodiment, even if an error occurs between the estimated recycle time and the actual recycle time, the correction processing is performed so as not to interfere with the photographing, so that a reliable red-eye mitigation function can be obtained. It guarantees continuous shooting with, shortens the time lag until release, and improves the operability of the camera.

[0056]

As described above, according to the first aspect of the invention, the second shot is recycled based on the battery check voltage and the recycling time of the first shot in the continuous shooting mode in flash photography. By predicting and calculating the time, and turning on the red-eye lamp during the charging operation and turning it off when charging is complete, the red-eye reduction effect and the release effect can be achieved in the second shot when the continuous shooting is performed when the battery is exhausted or at low temperatures. It is possible to improve both the operability of the camera and the shortening of the time lag.

According to the second aspect of the present invention, the recycle time of the third shot is based on the battery check voltage and the recycle time of the second shot in the continuous shooting mode in flash photography, By predicting and calculating the recycle time of the nth shot based on the battery check voltage and the recycle time, starting the lighting of the red-eye lamp during the charging operation and turning it off when the charging is completed,
It is possible to improve the operability of the camera by making the red-eye mitigation effect and shortening the time lag until release compatible both in the third shot and the n-th shot when continuous shooting is performed when the battery is significantly consumed or when operating at low temperatures. .

According to the third aspect of the invention, in the continuous shooting mode in flash photography, the recycle time of the second shot to the nth shot is predicted and calculated based on the battery check voltage of the first shot and the recycle time. By starting the lighting of the red-eye lamp during the charging operation and turning it off when the charging is completed, both the red-eye mitigation effect and the shortening of the time lag until the release are achieved in each shot after the second shot by the simplified control. The operability of the camera can be improved.

According to the invention of claim 4 or 5, when the predicted recycle time of the shot has an error from the actual recycle time, the release is performed before the charge completion voltage is reached, or the red-eye lamp is turned off. Since the lighting time is shortened below the predetermined time to be corrected, even if an error occurs in the estimated recycling time value in the continuous shooting mode of flash shooting, the shooting can be continued without any trouble.
