The microcomputer (μC _FL ) 600 calculates the dimming amount of the flash FL1 in the main light emission based on the light emitting amount of the flash FL1 monitored in the preview mode, and also generates a predetermined V _ref signal corresponding to this dimming amount. The _Vref signal is emitted to the light emission amount monitor circuit 606.
And outputs the variable voltage source VR2 to a predetermined reference voltage value V _ref
Set to.

In the main light emission, when the xenon tube 65 of the light emitting circuit 605 emits light, the monitor circuit 606A monitors the light emission amount, and the collector voltage Vc of the transistor Tr30 decreases according to the light emission amount. Then, when the collector voltage Vc drops below the reference voltage value V _ref , the comparator COMP2 outputs a signal indicating that the flash light emission amount has reached a predetermined light emission amount, that is, a light emission stop signal STP2.

Next, the operation will be described. First, the control operation by the microcomputer (μC1) 1 will be described with reference to FIGS.
2 is used for the explanation. First, various flags will be described. Table 2 shows the name of each flag, the contents of its set state and reset state, and the microcomputer to which the flag is applied.

In the table, the mark "○" indicates "applied" and the mark "-" indicates "not applied". The flag PVF and the flag DPIF are applied to two types of microcomputers, but the processing of each microcomputer is independent of each other, and the states of these flags do not affect the processing of the other microcomputer. .

[Table 3]

FIG. 27 shows an interrupt routine executed when the switch S ₁ , the recording start switch S _REC or the grip switch S _GR is turned on. When an interrupt occurs, the microcomputer (μC1) 1 resets all flags and prohibits other interrupts to this flowchart (# 2, #
4). Then, data indicating the operation states of various switches is input (# 6), and a subroutine "switch data input" (see FIG. 28) is executed to perform control according to those switch operations.

FIG. 28 shows the "switch data input" subroutine. First, it is determined whether the transceiver TX is attached to the camera body 20 and the switch _SREM is turned on (# 30). If the switch S _REM is on, remote control is performed, so the switch data sent from the transceiver RX is stored in the internal RAM of the microcomputer (μC1) 1 (# 32), and if the switch S _REM is off. , Monitor all the switches on the camera body 20 side,
The monitoring result is stored in the internal RAM (# 34),
To return. Any subsequent detection of the state of the switch is determined by the contents stored in this internal RAM.

Returning to FIG. 27, next, it is judged from the switch data stored in the internal RAM whether or not this interrupt is caused by turning on the switch S ₁ (#
8). If the switch S ₁ is on, the process moves to the “S1 ON” subroutine (see FIG. 51) (# 10). If it is not on, it is judged whether or not the switch _SREM of the transceiver TX is turned on (# 12), and if it is on, a subroutine of " _SREM " to perform this control (see FIG. 29). Is executed (# 14), and the switch S _REM
If is not turned on, the video recording switch S _REC
It is determined whether is turned on (# 16). If the moving image shooting switch S _REC is turned on, the moving image subroutine “REC” (see FIG. 60) is executed (# 1
8) If it is not turned on, the "eyepiece" subroutine (see FIG. 30) is executed (# 20), and thereafter, # 2
Go to 2. In # 22, CCD / monitor / recorder 10
The transistor Q1 is turned off to stop the power supply to etc., and further interrupts to this flowchart are returned to the enabled state, and then stopped (# 24, # 26).

FIG. 29 shows the "S _REM " subroutine. First, the "S1 ON" subroutine described later is executed (# 40), and the switch S _{REM of the} transceiver TX is executed.
It is determined whether is turned on (# 42). If it is turned on, a flag SREMF indicating this is set (# 44) and the process returns, and if it is not turned on,
Return as it is.

FIG. 30 shows the "eyepiece" subroutine. First, it is determined from the eyepiece flag SGRF whether or not eyepiece detection is performed (# 50). When the eyepiece detection is not performed, the count value N for timing is returned to "0", and the eyepiece flag SGRF indicating that this flowchart for eyepiece detection is executed is set (# 52, #). 54). Next, microcomputer (μC1)
1 turns on the light emitting element 291 of the eyepiece detection sensor 29 for 10 msec, and inputs data from the light receiving element 292 during that period (# 56, # 58).

Then, it is judged whether or not there is light reception data (# 60). If there is no light reception data, # 62 to # 6.
The process shifts to 6 and it is determined whether or not the state without eyepiece continues for 2 seconds or more. That is, the count value N is incremented, and then it is determined whether N = K _N (#
62, # 64). If N = K _N, it is determined that the state without eyepiece continues for 2 seconds, the eyepiece flag SGRF is reset (# 66), and the process returns. On the other hand, if N = K _N , the process returns to # 56.

If there is light reception data in # 60, it is determined that the photographer is looking into the finder 28, the transistor Q1 is turned on, and power is supplied to various circuits (# 68). Then, after waiting for 10 msec in order to wait for stabilization of the photometric and dimming circuit 9, the photometric data is captured (# 70, # 72). Then, the exposure calculation is performed from the photometric data in # 72 (# 74), then the subroutine "AF-1" (see FIG. 33) is executed to perform automatic focus adjustment (# 76), and then waits for 100 msec. Is performed (# 78).

FIG. 31 shows the "exposure calculation" subroutine. In the exposure calculation, first, it is determined from the result of the shooting mode setting whether the shooting mode is one of the silver salt still mode and the electronic still mode (# 100, # 10).
2) If both modes are not set, data that does not display aperture value (AV) / shutter speed (TV) is set (# 104), and the flow returns without performing exposure calculation.

On the other hand, when the photographing mode is either the silver salt still mode or the electronic still mode (YES in # 100 or # 102), the sensitivity SV of the loaded film is read by the film sensitivity reading device 6 (# 106). ), The exposure value EV (= BV + SV) is obtained by adding the photometric value BV to this (# 108), and the exposure value EV is corrected by adding the exposure correction amount ΔEV _AMB for constant light to this exposure value EV. (# 110).

Subsequently, it is judged whether or not the MFL photographing mode is set (# 112), and if it is not the MFL photographing mode (flag MFLF = 0), the exposure amount of the flash light amount corrected for exposure ( .DELTA.EV _FL) is performed of the correction, and the correction of the flash light quantity, the fed back so as to change the variable voltage source VR as the correction i.e. dimming amount (# 114). The light emission amount itself may be adjusted by this correction amount.

If the MFL photographing mode is set in # 112 (flag MFLF = 0), the flash emission amount itself is corrected, so that the exposure is not corrected and step # 114 is skipped.

Subsequently, the exposure mode is discriminated (# 1
16) In the P mode, it is determined whether or not the main flash FL1 is attached (# 118). If the main flash FL1 is attached, FL exposure calculation is performed based on the exposure value. (# 120), AV / TV
(Aperture value / shutter speed) is calculated. If the main flash FL1 is not attached, based on the presence or absence of the recording mode determined based on the result of the shooting mode setting (# 122), the exposure calculation I for the constant light based on the constant light is performed.
Or, exposure calculation II for ambient light is applied (# 124, # 12
6), AV / TV is required.

FIG. 32 shows an AV / TV program diagram. In this figure, the exposure calculation I for stationary light is represented by a diagram, and the exposure calculation II for stationary light is represented by a diagram. .

In FIG. 32, the diagram shows that the diaphragm has the minimum value A.
Shutter speed is 1/6 between Vmin and maximum value AVmax
Fixed to 0 seconds, diaphragm is below minimum AVmin and maximum A
If Vmax or more, the aperture is set to the minimum value AVmin or the maximum value AVmax.
The shutter speed TV is changed according to the brightness.

This diagram is adapted to the field (screen scanning) period of the television scan, and is used to control the aperture and shutter speed during the shooting of only the moving image or during the shooting preparation. When the aperture reaches the maximum value AVmax, 1 /
Maximum aperture value of AVmax up to shutter speed of 250 seconds
It is controlled as it is. This value of 1/250 seconds is set as the limit of the range that can be viewed on a television as a moving image.

The diagram is for still photography when no moving image is recorded, and the aperture and the shutter speed change at the same rate with respect to the brightness. Instead of this diagram, a program diagram for high speed, a program diagram for prioritizing the aperture opening effect for portraits, etc., or a program diagram for setting a large depth of field may be adopted. Good.

The diagram is a program diagram for still shooting during recording. The point a at 1/250 second and the maximum aperture value AV
It is connected with the b point of max. The purpose of this is to reduce the aperture change when moving from the movie shooting mode to the still shooting, to increase the shutter speed to reduce camera shake and image shake, and to satisfy the continuity of movies. Therefore, the shutter speed is 1/250.
It has been pressed by the second.

If the exposure mode is the A mode, the S mode or the M mode, the well-known exposure calculation is performed to obtain the AV / TV (# 128, # 130, #).
132) and returns.

FIG. 33 shows the "AF-1" subroutine. The AF-1 process is performed so that the main subject is automatically selected when the area detected by the line of sight is not set, and the lens is driven according to the defocus amount of the area selected from the 15 areas. To do.
First, the image data stored on the CCD / monitor / recording unit 10 side is input to the microcomputer (μC1) 1 in response to a read instruction from the microcomputer (μC1) 1 (# 14
0), each defocus amount of 15 areas is calculated based on this input image data (# 142). Then, the area closest to the camera body 20 is selected as the main subject (# 144), and the lens is driven based on the defocus amount (# 14).
6) Return.

Returning to FIG. 30, next, the preparation for photographing is performed at # 80. This "shooting preparation" subroutine is shown in FIG.
It is shown in FIG. Here, first, the line-of-sight is detected, and the area for performing photometry and distance measurement processing is detected (# 150). Next, switch data for selecting various controls is input (# 152). Based on this switch data input, the color temperature change mode setting (# 15
4) and MFL shooting mode setting (# 156), shooting mode setting (# 158), exposure mode setting (# 16)
0) and AV / TV setting (# 162).

AF and AE (including exposure calculation) processing is performed based on the set area, switch data and set control value (# 164), and these data are stored in the main flash FL1 and other areas. Flash FL2
After communication is made between FL3 (# 166), it is output to the microcomputer (microphone C2) (# 168) and the process returns.

Here, the subroutine "line of sight detection" of # 150 will be described with reference to FIG. In the line-of-sight detection, first, it is judged whether or not the switch S _REM of the transceiver TX is turned on (# 170). If the switch S _REM is turned on and the remote control state is set, the fact is displayed on the liquid crystal display unit R8. Is displayed and there is no need to look into the finder, so the function of line-of-sight detection is unnecessary and the process returns. vice versa,
If the switch S _REM is off, the image displayed on the monitor 47 is checked through the finder, so that the process proceeds to step # 172 in order to control the gaze detection.

In # 172, the light emitting portion (infrared LED) in the visual axis detection circuit 2 is turned on for 10 msec, the emitted light is reflected by the eye of the photographer looking into the finder 28 and is received by the infrared area sensor. The received light data is taken in (# 174). The line-of-sight area seen by the photographer's eye is detected from the captured data, and the detected line-of-sight area is captured as an area AR (N) (N = 1 to 16) (# 176).

Next, the area AR (N) becomes the area AR16.
It is determined whether or not (# 178). In the case of the area AR16, it is determined that the area cannot be detected because it is not within the detection area, and it is determined whether or not the timer flag TMF for measuring the time between them is reset to "0"(# 180), and the timer If the flag TMF is reset, after the timer T _AR is reset and started,
The timer flag TMF is set (# 182, # 18
4).

At # 180, the timer flag TMF is set
Timer T_ARIs being timed by
, Skip # 182 and # 184 and move to # 186.
To go. In # 186, timer T_ARHas timed 5 seconds
It is determined whether the timer T _ARIs 5 seconds before
If 5 seconds have passed after turning, the line-of-sight detection area frame 19
Is set and the data for displaying is returned.
(# 188). On the other hand, in # 178, the detected area is
If the area is not AR16, the timer flag TMF is reset.
(# 190) and then the line-of-sight detection area frame 19
The data to be displayed is reset (# 192).

Subsequently, the area AR (N) in which the line of sight has been detected
It is determined whether or not the switch S _SDI for setting or resetting has been turned from off to on (# 19
4). If the switch S _SDI is not turned on from off, the process directly returns. If the switch S _SDI is turned on from off, it is determined whether or not the area reset flag RSTF is set to "1"(# 1).
96). If the area reset flag RSTF is set to "1", this flag is reset to "0",
Next, the current detection area AR (N) is set as the setting area LARN (# 208), the area flag ARF indicating the area designation is set (# 210), and then the process returns.

On the other hand, if the area reset flag RSTF is not set to "1" in # 196, it is determined whether or not the set area LARN and the current detection area AR (N) are equal (# 198). If both areas are equal,
It is determined that the switch S _SDI has been operated to cancel the designated area LARN, the area reset flag RSTF is set to "1"(# 200), and then the line-of-sight detection area frame 19 displayed when the power is turned on. The data for the display is set (# 202), the area flag ARF is reset (# 204), and the flow returns. # 198
If the setting area LARN and the current detection area AR (N) are not equal to each other, it is determined that the switch S _SDI has been operated to set the area, and the process proceeds to # 208.
After R (N) is set as the set area LARN and the area flag ARF indicating the area designation is set (# 208, # 210), the routine returns.

Next, the # 154 "color temperature change mode setting" subroutine will be described with reference to FIG. First,
It is determined whether or not the MFL shooting mode is set (# 220), and if the MFL shooting mode is set (YES in # 220), the color temperature of the main flash FL1 is not changed, and the process immediately returns. To do. MF
The color temperature is not changed when the L shooting mode is set, as described above, because the color temperature changing function is the main flash FL.
1 has the flash FL2, FL3 does not have, so changing the color temperature of the main flash FL1 in the MFL shooting mode will complicate the color temperature of the flash light applied to the subject. This is because the MFL shooting mode and the color temperature change mode cannot be set to overlap each other for avoidance (see the processing of # 234 and # 236 of the MFL shooting mode setting in FIG. 37).

If the MFL photographing mode is not set in # 220 (NO in # 220), it is subsequently determined whether or not the color temperature change switch S _LC is turned from off to on (# 222). If the color temperature change switch S _SDI is not operated (NO in # 222), the instruction regarding the color temperature change of the main flash FL1 has not been input, and therefore the process directly returns.

If the color temperature change switch S _SDI is turned on from off (YES in # 222), it is further determined whether or not the flag LCF indicating the color temperature change mode is set to "1"(# 224), the flag LCF is "1"
If the color temperature change switch S _SDI is operated, it is determined that the color temperature change mode is released, and the flag LCF is reset to “0” (#
226), and returns. On the other hand, the flag LCF is "0".
If the color temperature change switch S _SDI is operated, it is determined that the color temperature change mode is set, and the flag LCF is set to "1"(# 2).
28) and returns.

Subsequently, the subroutine of "MFL shooting mode setting" of # 156 will be described with reference to FIG. First,
It is determined whether or not the flag MFLF indicating the MFL shooting mode is set to "1"(# 230), and the flag M is set.
If the FLF is not set to "1" (NO in # 230), it is determined whether or not the MFL shooting mode setting switch S _MFL is turned from OFF to ON to set the MFL shooting mode (# 232).

If the MFL photographing mode setting switch S _MFL is not operated (NO in # 232), the process returns and the MFL is set.
When the photographing mode setting switch S _MFL is turned on from off (YES in # 232), it is further determined whether or not the flag LCF indicating the color change mode is set to "1"(# 234), and the flag is set. If LCF is set to "1" (color temperature change mode is set), MF
The process returns to prevent duplicate setting of the L shooting mode.

On the other hand, if the flag LCF is not set to "1" in # 234 (the color temperature changing mode is not set), the MFL photographing mode setting switch S is set.
_{The MFL} operation is determined to be the MFL shooting mode setting, the flag MFLF is set to "1"(# 236), and the process returns.

Further, the flag MFLF is "1" in # 230.
If set to, the MFLF shooting mode has already been set, so the MFL shooting mode should be canceled.
It is determined whether or not the shooting mode setting switch S _MFL has been turned on (# 238). If the MFL shooting mode setting switch S _MFL has not been operated, the process returns and the MFL shooting mode setting switch S _MFL has been operated. If so, it is determined that the MFL shooting mode has been canceled, the flag MFLF is reset to "0"(# 240), and the process returns.

Next, the "shooting mode setting" subroutine of # 158 will be described with reference to FIG. First, it is determined whether or not the flag MDTF indicating that the shooting mode is set is set to "1"(# 250), and the flag MDT is set.
If F is not set to "1", it is determined whether or not the shooting mode change switch S _MDT is turned on to set the shooting mode (# 252).

If the photographing mode change switch S _MDT is switched from OFF to ON, it is judged that the photographing mode is set, and the flag MDTF is set to "1"(# 254).
If the shooting mode changing switch S _MDT is not turned on from off, the process returns.

If the flag MDTF is set to "1" in # 250, the photographing mode has already been set, and accordingly the photographing mode number N _M (Table 1) is set according to the operation of the front dial 33 or the rear dial 34. (Reference) is cyclically changed from 1 to 7 (# 256).

When the photographing mode change switch S _MDT is turned from off to on (YES in # 258), the flag MDTF is reset to "0"(# 260) because the setting of the photographing mode is completed, and the process returns. If the shooting mode change switch S _MDT is not operated (# 258: N
O), the process is returned because the shooting mode is being set.

The "exposure mode setting" subroutine will be described with reference to FIG. 39, and the "AV / TV setting" subroutine will be described with reference to FIG.

In the "exposure mode setting" subroutine, it is first determined whether or not the flag MDF indicating that the exposure mode is being set is set (# 270). If the flag MDF is not set, then the exposure is set. It is determined whether the mode change switch S _MD has been turned from off to on (# 272).

If the exposure mode change switch S _MD is turned from off to on (YES in # 272), the flag MDF is set to "1" because the exposure mode is set, while the exposure mode change switch S is set. _{If the MD} is not turned on from off (NO in # 272), the process directly returns.

If the flag MDF is set to "1" in # 270, the exposure modes A, M, S and P are cyclically changed in this order in accordance with the operation of the front dial 33 and the rear dial 34. (# 276). Next, it is determined whether or not the exposure mode change switch S _MD is turned from off to on (# 278), and if the exposure mode change switch S _MD is turned from off to on (YES in # 278), the exposure mode If the setting is completed, the flag MDF is reset to “0” (# 280), the process returns, and if the exposure mode changing switch S _MD has not been operated from OFF to ON (NO in # 278), it remains as it is. To return.

In the "AV / TV setting" subroutine, first, the flag MDF indicating the exposure mode setting, the flag ECRF indicating the exposure correction by the constant light, the flag ECR _FL F indicating the exposure correction by the flash light and the white balance correction are set. It is determined whether or not the respective flags WBF shown are set to "1"(# 290 to # 29).
6) If any one of them is set to "1", it is determined that the mode is set, and the process directly returns. If neither is set to "1"(# 29
(NO in 6), the currently set exposure mode is determined (# 298), and the following processing according to the set exposure mode is performed.

That is, when the exposure mode is the P mode, the shutter speed TV corresponds to the increase / decrease of the aperture value AV.
Performs a so-called P shift process of increasing or decreasing in the opposite direction (# 300). If the exposure mode is the A mode, the aperture value AV is changed (# 302). If the exposure mode is the S mode, the shutter speed TV is changed (#
304). If the exposure mode is the M mode, the aperture value AV is changed by operating the front dial 33 (# 306), and the shutter speed TV is changed by operating the rear dial 34 (# 308). And after these processes, it returns.

Next, the "AF / AE" subroutine will be described with reference to FIG. In this subroutine, first, photometric data is input (# 310), and then G in the image data of R, G, B from the microcomputer (μC2) 100.
(Green) data is input (# 312). Next, it is judged whether or not the control changeover switch S _REM of the transceiver TX is turned on (# 314). If the control changeover switch S _REM is turned on, the line-of-sight detection is not necessary as described above. After executing the subroutine "AF-1" to perform temporary focus detection (# 320), the photometric value BV is captured (# 322), and the exposure calculation is performed based on the photometric value BV (# 324). .

If the control changeover switch S _REM is not turned on (NO in # 314), the line-of-sight area setting switch S
Area flag A based on the operation of _SDI (operation member 30)
It is determined whether RF is reset to "0"(# 316).

If the area flag ARF is reset to "0" (YES in # 316), it is determined whether or not the area reset flag RSTF is set to "1"(# 318). When the area reset flag RSTF is set, it is not known to which area AR (N) the AF processing and the AE processing should be performed. Therefore, the AF / AF operation is performed until the area AR (N) is set next time.
Skip # 320- # 324 to lock the AE,
The focus flag AFEF indicating the focus is reset to "0"(# 326) and the process returns.

If the area reset flag RSTF is reset to "0" (NO in # 318), it means that the area AR (N) has never been set since the power was turned on. In this case, various areas are always set. Considering that it is better not to lock AF / AE so that AF processing and AE processing can be performed on a subject, the above-mentioned subroutine "AF-
1 ”is executed to repeat temporary focus detection (continuous AF), the photometric value BV is taken in each time, and exposure calculation is performed based on the photometric value BV, and then a focus flag indicating focus is obtained. Reset AFEF to "0"(#
320- # 326), and returns.

On the other hand, at # 316, the control changeover switch S
_SDI and (operating member 30) by the area flag ARF is set to "1" (NO in # 316), whether the switch S ₁ is turned on is determined (# 3
28). If the switch S ₁ is not on, the focusing flag AFEF is reset to "0" so as to set the AF mode to continuous for photographing in the eyepiece or the recording photographing mode (# 330). If switch S ₁ is on,
Skip # 330 and proceed to # 332.

At # 332, it is determined whether or not the focus flag AFEF indicating that the focus is once set is set to "1". If the focus flag AFEF is set (YES at # 322), that is, Once in focus, it returns without performing focus detection again (one-shot AF).

If the focus flag AFEF is not set (NO in # 332), focus detection is performed, and it is determined whether or not focus is achieved based on the result (# 334, # 3).
36). If it is not in focus, the taking lens 211 is driven based on the result of focus detection (# 338), # 334.
Then, the focus detection is performed again.

When it is determined that the object is in focus (YES in # 336), the in-focus flag AFEF indicating that the object is in focus is set to "1"(# 338), and photometry is performed (#).
342), and returns.

The "focus detection" subroutine will be described with reference to FIG. 42, and the "photometry" subroutine will be described with reference to FIG.

In focus detection, the set area AR
Defocus amount D in area AR corresponding to (N)
F _N is calculated and the process returns (# 350).

Next, "photometry" will be described. Table 4 is a table showing the relationship between the detected line-of-sight area and the photometric data.

[0192]

[Table 4]

In photometry, first, the subject distance DV is calculated based on the lens extension amount, the focal length f is further taken in, and the image magnification β is calculated from the subject distance DV and the focal length f (# 360). ~ # 364). Then, it is judged whether or not the obtained image magnification β is equal to or larger than a predetermined value K _B (# 366).

If the image magnification β is equal to or larger than the predetermined value K _B , the photometric data of the area AR (N) is output from the CCD / monitor / recording unit 10 based on “Photometry A” in Table 4 above, and the average of them is output. The value is calculated (# 368, # 372). On the contrary, if the image magnification β is less than the predetermined value K _B , the photometric data for the area AR (N) is output based on the “photometric B” in Table 4 and the exposure calculation is performed from the photometric data. It is executed (# 370, # 372). In the above, when the image magnification β is small, the photometric data of a plurality of areas are averaged so that the entire landscape or the like can be photographed appropriately.

Returning to FIG. 30, after the photographing preparation processing is executed, it is judged whether or not the switch S ₁ is turned on (# 82). If switch S ₁ is on,
The "S1ON" subroutine is executed (# 84), and it is further determined whether or not the grip switch S _GR is on (#
86), if the grip switch S _GR is on, then # 80
Return to On the other hand, if the grip switch S _GR is off (NO in # 86), the process proceeds to # 66, resets the flag SGRF to “0”, and then returns.

If the switch S ₁ is not turned on in # 82, it is judged whether or not the recording start switch S _REC for starting the recording of the moving image is turned on (# 88), and the recording start switch S _REC is turned on. If there is, a "REC" subroutine for recording described later is executed (# 90).
On the other hand, if the recording start switch S _REC is not on, the "playback" subroutine is executed (# 92).

Now, the "reproduction" subroutine will be described with reference to FIGS. First, it is determined whether the shooting mode is set to silver salt still or electronic still (# 380, # 382), and when neither shooting mode is set (NO in # 382), preview (preliminary) and posterior Prohibit confirmation control and return. If the shooting mode is either silver salt still or electronic still, to control the preview and post confirmation #
Move to 384. In # 384, it is determined whether or not the flag RECF indicating recording is set to "1". If the flag RECF is set to "1" (during recording), the preview operation by the monitor 47 is performed. And return to prohibit the post-confirmation display operation.

[0198] (if not during recording) flag RECF is "1" if it is not set in, the monitor display instruction switch S _PV is discriminated whether it is from the off state to the on state (# 386), the monitor display instruction switch If _SPV is on from off, the "preview" subroutine (FIGS. 57 and 58) is executed (# 388), and the process returns.

[0199] monitor display instruction switch S _PV is to be turned on from off (NO at # 386), is determined is whether there are more still image display instruction switch S _DPI is turned on from off (# 390), If the still image display instruction switch S _DPI is turned on, the process proceeds to step # 392 to reproduce the stored still image and display it on the monitor 47.

At # 392, it is determined whether or not the flag DPIF indicating that the still image display mode is set is set to "1". If the flag DPIF is set (YES at # 392). , flag DPIF as the operation of the monitor display instruction switch S _PV is released still image display mode is reset to "0"(# 39

Subsequently, the "exposure correction" subroutine (FIGS. 46 and 47) described later is executed to correct the exposure control value (# 412), and the "color correction" subroutine (FIG. 50) described later is executed. By executing the color correction processing of the display image on the monitor 47 (# 414), the calculated exposure correction amount and color correction amount data is output to the microcomputer (μC2) 100 (# 416). # 3
Return to 90.

[0204] In addition, at # 390, unless the monitor display instruction switch S _PV is operated, whether or not the flag DPIF has been set to "1" is determined (# 41
8) If the flag DPIF is reset to "0" (NO in # 418), the process returns.

On the other hand, if the flag DPIF is set (YES in # 418), the process proceeds to # 412, and after exposure correction processing and color correction processing are performed (# 412, # 41).

Return to 390.

The "exposure correction" subroutine will be described below with reference to FIGS. 46 and 47. First, it is judged whether or not the flag ECRF indicating the exposure correction mode in the stationary light shooting is set to "1"(# 42).
0), when the flag ECRF is not set, it is determined whether or not the exposure compensation switch S _{(+/-) AMB} is switched from off to on (# 422), and the exposure compensation switch S _{(+/-) AMB is determined.} # 4 if not turned from off to on
Move to 32. On the other hand, if the exposure compensation switch S _{(+/-) AMB} is switched from OFF to ON (NO in # 422),
The flag ECRF is set to "1"(# 424), assuming that the exposure compensation mode in the constant light photography has been set,
Return to 420.

If the flag ECRF is set in # 420, the exposure correction amount ΔEV _AMB in the constant light is set according to the operation amount of the front dial 33 and the rear dial 34, and then the exposure correction switch S _{(+ It} is determined whether or not the _{/-) AMB} is turned on (# 428). If the exposure compensation switch S _{(+/-) AMB} is not turned on from off, it returns as it is, and if it is turned on from off, the exposure compensation mode is canceled and the flag ECRF is set to "0".
To reset (# 430) and return.

At step # 432, it is judged if the flag ECR _FL F indicating the exposure correction mode in flash light photography is set to "1". If the flag ECR _FL F is not set, the exposure correction switch S
_It is determined whether the _{(+/-) FL} is turned from off to on (# 434). If the exposure compensation switch S _{(+/-) FL} is not turned from off to on, the process returns, and then from off to on. If so, the flag ECR _FL F is set to "1"(# 436), assuming that the exposure correction mode in flash light photography has been set, and the process returns to # 432.

If the flag ECR _FL F is set to "1" in # 423, it is further determined whether or not the flag MFLF indicating the MFL photographing mode is set to "1"(# 438). If the flag MFLF is set, the light emission number N _MF is set according to the operation of the light emission number setting switch S _MFN (# 440), and the light emission number N _IL is set according to the operation of the front dial 33. In accordance with the operation of the dial 34, the exposure correction amount ΔEV _FL of the flash light with respect to the captured image of the emission number N _IL is set (# 442, # 444). The above emission number N _IL
Indicates a photographed image for which exposure compensation is performed, and is designated by a number in the flash emission order, such as a photographed image at the time of the third flash emission.

On the other hand, if the flag MFLF is not set, the light emission number N _IL is set to "1"(# 44

The flag ECR _FL F is reset to “0” as the exposure compensation mode in flash light photography has been canceled (# 45
2) Return.

Next, the color correction processing will be described. There are various types of light sources for taking photographs. FIG. 48
(A) to (d) show a part of their spectral characteristics. Natural daylight is not spectrally biased, but tungsten light is biased in the red region. .

On the other hand, the color film is R (red), G
Each of the three colors of (green) and B (blue) has three photosensitive layers having a sensitivity for each color, and all the colors are produced with this B / G / R ratio. The spectral sensitivity to light that these three layers have can be roughly divided into two types, one is a daylight type that is balanced so that normal colors can be reproduced when taken with natural light or flash light during the day. Yes, the other one is a tungsten type that is balanced so that a normal color can be reproduced when the image is taken with tungsten light.

FIGS. 49 (a) and 49 (b) show examples of the spectral sensitivities of both types. As can be seen from FIG. 49, the daylight type film has a R value higher than that of the tungsten type film. Because of its high sensitivity to light, when taken with tungsten light that has a large amount of R component, the image becomes reddish. This is because human vision has color adaptability and can accurately recognize the color of an object illuminated by tungsten light, whereas color film does not have human-like color adaptability. .

As described above, since the color temperature of the photograph taken on the film is different depending on the light source, it is possible to correct the inappropriate color temperature to an appropriate color temperature while monitoring the color temperature of the photograph before and after photographing. Is extremely useful in photography. In the color correction processing, the image to be captured is displayed on the monitor 47 in order to properly correct the color temperature of the image to be captured before the image is captured, and the display image of this image is displayed according to the operation amount of the switch operation by the operator. The color temperature is corrected.

Next, the "color correction" subroutine is shown in FIG.
Will be explained. First, the flag W indicating the color correction mode
It is determined whether or not BF is set to "1"(# 460), and if the flag WBF is not set, then it is determined whether or not the color correction switch _SWB is turned from off to on (# 462).

If the color correction switch _SWB is on from off, the above flag WBF should be set to set the color correction mode.
Is set to "1"(# 464) and the process returns. On the other hand, if the color correction switch _SWB is not turned on from off, the process skips # 464 and returns.

If the flag WBF is set in # 460, it is determined that the color correction mode is set, and the blue and red correction amounts Δ are set according to the operation of the front dial 33 and the rear dial 34.
B _C and ΔR _C are set (# 466, # 468). Then, it is determined whether or not the color correction switch _SWB is turned from OFF to ON (# 470), and if the color correction switch _SWB is turned from OFF to ON (YES in # 470), the color correction mode is released. Therefore, the flag WBF is reset to "0"(# 472), the process returns, and if the color correction switch _SWB is not operated (NO in # 470), the correction is in progress.
Skip 472 and return.

When the "reproduction" subroutine ends, returning to FIG. 30, it is determined whether or not the grip switch S _GR is turned on (# 86). Grip switch S

If the still image display instruction switch S _DPI is turned on from off, after the display control I for displaying a still image is executed (S16), the process proceeds to S26, and the still image display instruction switch S _PDI is turned on. If not, it is further determined whether or not the flag DPIF indicating the still image display mode is set to "1" (S1).
8) If the flag DPIF is reset to "0" (NO in S18), the process proceeds to S26.

On the other hand, if the flag DPIF has been reset to "1" (YES in S18), the display control II for changing the display is executed (S20), and the "color correction" subroutine described above is executed. Then, the color correction process is performed (S22), the "exposure correction" subroutine is executed to perform the exposure correction process (S24), and then the process proceeds to S26.

At S26, color correction is carried out, and then the above-mentioned marks and characters showing the photographing mode are displayed (S28). Then, the display data from the microcomputer (μC1) 1 for displaying the shutter speed and the photographing mode is output to the microcomputer (μC21) 120 which performs image processing, and further based on the input image data (R, G, B). Then, the aperture value in the moving image is calculated, and the exposure control II is performed based on the calculated aperture value (S30). Further, WB control is performed by the WB control data obtained based on the input image data (R, G, B) (S32), and the process returns to S6.

Next, the "exposure control I" subroutine will be described with reference to FIG. First, the variables N _E and N _T are reset (S40, S42). The variable N _E indicates the number of exposure operations every 1/60 seconds during one shooting, while the variable N _T indicates the required number of exposure operations every 1/60 second during one shooting. is there.

[0256] Then, the microcomputer (.mu.C1) shutter speed TV input from 1 is converted into a real time T _CCD (S44), the shutter speed TV is APEX value 6 or more (corresponding to 1/60 seconds of the shutter speed) It is determined whether or not (S46).

If the shutter speed TV is the apex value 6 or more, the process proceeds to S56 (YES in S46), and if the shutter speed TV is less than the apex value 6 (S4).
NO 6), the variable N _T T _CCD / (1/60) consisting calculated value is set to (S48), are further set the variable N _T is the variable N _AGC (S50). Subsequently, the exposure time T _CCD is set to 1/60 seconds which matches the field time (S5
2) A flag MEXPF indicating that the exposure operation is repeated N _T times in 1/60 seconds is set to “1” (S54).

In this embodiment, moving image shooting and still shooting (including both silver salt still shooting and electronic still shooting) are possible. 1/3 with CCD43 for movie shooting
One field is imaged every 60 seconds, and the captured image is recorded. In still photography,
In particular, when the exposure mode is the P mode and the A mode, an arbitrary shutter speed (exposure time) TV is determined according to the brightness.

When the shutter speed TV is 1/60 seconds or more, in moving image shooting, image pickup is repeated every 1/60 second, and the _AGC 109 adjusts the gain based on the N _AGC. It handles exposure times longer than 60 seconds, while still photography uses 1
Exposure times longer than 1/60 second are addressed by summing multiple minutes of images obtained at every / 60 second exposure.

At S56, the exposure OK signal is output to the microcomputer (μC1) 1. The microcomputer (μC1) 1 starts exposure control based on the photographing method set as described above. Then, it waits for an exposure start signal to be input from the microcomputer (μC1) 1 (S58), and when this signal is input, a flag E indicating that exposure is being performed is performed.
XPF is set to "1" (S60). Subsequently, after the exposure is completed and the flag EXPF is reset to "0" (S62), the process returns.

The detection range in the exposure, WB, and shake detection described later in the moving image shooting mode is the entire range of the line-of-sight detection display frame 19 in FIG. 15, which is different from the range of line-of-sight detection in still image shooting. . The reason for this is that if the brightness and color change due to changes in the exposure and WB detection ranges, the image exposure and color change frequently following this, making it difficult to see the screen in a moving image. This is because if the range of shake detection is narrow, it is difficult to distinguish the shake of the camera itself from the shake (moving body) of the subject.

FIG. 65 shows the CCD / monitor / recording unit 10.
Below is a timing chart to explain the operation of
The outline of the operation will be described with reference to this figure.

First, the case of stationary light photography will be described. In the figure, in the "Operation" of the uppermost, the release switch S ₂ is turned on, data indicating the photographing from the microcomputer (.mu.C1) 1 to the microcomputer (μC2) 100 is output "Data Output". The microcomputer (μC1) 1 performs predetermined control for photographing, and the microcomputer (μC2) 100 receives the above data and performs predetermined control, and then performs “exposure O”.
The “K” signal is returned to the microcomputer (μC1) 1.

When the microcomputer (μC1) 1 receives the exposure OK signal, it waits until the vertical synchronizing signal V _sync of the next cycle is input, and then sends the “exposure start” signal to the microcomputer (μC2).
"Shutter exposure control" in which the aperture is controlled by transmitting to 100 and "iris control", and thereafter the shutter 46 is driven. The microcomputer (μC2) 100 controls the exposure of the CCD 43 at the cycle of the vertical sync signal V _sync of the next cycle.
D exposure control ".

Now, let us say that the image picked up at the first time in the exposure control for each vertical synchronizing signal V _sync is A1, and the second and subsequent times are A2, A3, ..., An. The signal of the first (first cycle) image A1 is the microcomputer (μC2) 100 after the exposure is completed.
The microcomputer (μC21) 120 performs predetermined image processing during the second period based on the signal from and is stored in the frame memories 121 and 122. The exposure control for the next image A2 is performed within the second period.

Here, the exposure time for proper exposure is 1 /
If it is 60 seconds or more, in the third cycle, the microcomputer (μC2) 100 outputs a control signal to the microcomputer (μC21) 120 to “adder ON”, turn on the adder circuit 124, and store in the frame memory 121. The image A2 is added to the image A1 and stored in the frame memory 122. After that, this process is repeated until the exposure control ends (Nth cycle), and the CCD is stored in the frame memory 121.
The image captured in 43 is stored in the frame memory 12
ΣAi (i =
The images 1, 2, ... N) are stored.

At this time, the images stored in the frame memory 121 are sequentially displayed on the monitor 47 in the next cycle to obtain a moving image. The moving image at this time is displayed with a slight underexposure, but when the still image display instruction switch S _DPI is operated, the microcomputer (μC
2) A signal for instructing “display switching” is output from 100 to the microcomputer (μC21) 120, which causes the above ΣAi
The processed still image is displayed with the proper exposure. On the other hand, when the exposure time is 1/60 seconds or less, the image Ai is stored in the frame memory 122 with a delay of one cycle. The image Bi (i = 1, 2, ... N) in the next exposure control is similarly processed.

Next, memory control during flash photography will be described. The exposure time at this time is 1/6
It is 0 seconds or less.

The captured image A1 is stored in the frame memory 122.
Is stored. At this time, the image O _N stored immediately before is stored in the frame memory 121 as it is, and this image is displayed. This is to prevent the noise from appearing to be mixed when only the image captured by flash photography for one cycle is included in the stationary light photography.

Next, referring to FIGS. 66 to 68, "V _sync
The “interrupt” will be described. When the vertical synchronizing signal V _sync is input, it is determined whether or not the flag EXENF indicating the end of exposure is set to "1" (S70). If the flag EXENF is set, it is determined that the exposure control has been completed, the flag EXENF is reset to "0" (S72), and subsequently, data for turning off the adder circuit 124 is set (S74) and input. The image data to be stored is directly stored in the frame memory 121.

Subsequently, the flag 1stF indicating the last exposure during exposure, the flag EXPF indicating during exposure, and the flag MEXPF indicating that the control requires a plurality of exposure operations are reset to "0" (S76). Up to S80), the continuous recording of the moving image is enabled, and further, the data for instructing the restart of the data input to the frame memory 121 is set (S82, S84). These S82, S8
By the processing of 4, the prohibition state of each data input at the time of FL photographing is released.

Subsequently, if the exposure is not being performed in the shooting mode of the silver salt still image or the electronic still image, the shutter speed T
A signal for setting V to 1/60 seconds is output to the timing signal generation circuit (TG1) 101 (S86). Also, A
A signal for automatically setting the GC circuit (AGC (I)) 105 is output, and the AGC circuit (AGC (I)
Signals for setting the gain of (I)) 109 to "1" are output (S88, S90), and a WB control signal is output (S92), and the process proceeds to S124. On the other hand, if the flag EXENF is not set in S70, it is determined whether or not the flag 1stF is set to "1" (S94). If the flag 1stF is set (YES in S94), the final exposure operation is completed, and since it is the next field, the "memory control" subroutine (FIG. 69) is executed to perform the memory control processing. (S96). Then, when the memory control process ends, it is determined whether or not the preview mode is set from the state of the flag PVF indicating the preview mode (S
98), if the preview mode is set (PVF
= 1), the process proceeds to S104, and if the preview mode is not set (PVF = 0), the flag EXENF is set to "1"(# 100), and the process proceeds to S86.

If the flag 1stF is reset to "0" in S94 (NO in S96), it is determined whether or not the flag EXPF is set to "1" (S10).
2) If the flag EXPF is set (during exposure), the process proceeds to S104, and if the flag EXPF is reset (if not exposed), the process proceeds to S86.

Now, the "memory control" subroutine will be described with reference to FIG. First, the microcomputer (μC
1) It is determined based on the input data from 1 whether or not flash photography is performed (S150). In the case of flash photography (YES in S150), a control signal for prohibiting the input of image data is output in order to prohibit the update of the stored contents of the frame memory 111 and the frame memory (I) 121 used when recording a moving image. (S152, S154), and subsequently, data for passing the image data as it is is set in the adder circuit 124 (S156). In this way, by prohibiting the data update and storing and holding the image of the previous screen (corresponding to the image O _N shown in FIG. 66), from one field in continuous continuous light imaging images. It is possible to prevent the noise-like display due to the inclusion of images taken by flash photography in several fields.

On the other hand, if it is not flash photography (S15
0 for NO), skip S152 and S154 and skip to S15
Go to 6.

Subsequently, it is judged from the setting state of the flag PVF whether or not the preview mode is set (S1).
58), if the preview mode is set (PVF
= 1), and it is further determined whether or not the number of preview photographing times N _PV input from the microcomputer (μC1) 1 is 2 or more (160). If N _PV ≧ 2 (YE in S160
S), from the input image data to the frame memory (III) 12
Data for creating new image data by subtracting the image data stored in S3 is set (S162), and S1 is set.
Go to 66. If N _PV <2 (N in S160
O), S162 is skipped and the process proceeds to S166. It should be noted that, in S162, since the input image data was captured using the flash light and the stationary light as the light sources, the image data captured using only the stationary light as the light source, which is stored in the frame memory (III) 123, is input. By subtracting from the image data, the image data captured by using only the flash light as the light source is obtained.

If the preview mode is not set in S158 (PVF = 0), the frame memory (I
Data for storing the image data is set in I) 122 (S164), and the process proceeds to S166. As a result, it is possible to make a post confirmation.

In S166, it is determined whether or not continuous shooting is performed,
If continuous shooting (YES in S166), internal memory 129
Data for instructing memory storage is set (S16
8) The process proceeds to S170, and if it is not continuous shooting (NO in S166), S168 is skipped and the process proceeds to S170.

In S170, it is determined whether or not the photographing mode is the electronic still mode. If the photographing mode is the electronic still photographing mode (YES in S170), data instructing the IC card 51 to store data is set (S172). ), The process returns and is not in the electronic still shooting mode (N in S170
O), skip S170 and return.

66 to 68, and in step S104, the exposure time T _CCD data is output to the timing signal generation circuit (TG1) 101, and then AGC (I) 1
A control signal is output to 05 and its gain is set to 1 (not amplified) (S106). Next, the WB is brought into non-control, and the flag 1stF is set to "1" (S108, S110).

Then, it is judged from the state of the flag MEXPF whether or not the control requires a plurality of exposure operations (S11).
2) If multiple exposure operations are required (MEXP
F = 1), it is determined whether or not the variable N _T is 1 (S11).
4). If the variable N _T is 1, it is the last exposure,
The process proceeds to S120. On the other hand, if the variable N _T is not 1,
The variable N _T is decremented by 1 (S116). At this time, since it is not at least the last exposure, the flag 1st
F is reset (S118), and the process proceeds to S120.

In S120, the variable N _E is incremented by 1, and the AGC circuit (II) 1 is set to optimize the exposure.
The gain of 09 is set to N _AGC (S122). Then, it is determined whether the variable N _E is 3 (S12).
4). If the variable N _E is 3, data for turning on the adder circuit 124 is set (S126), and then the image data stored in the frame memory (II) 122 and the latest data input from the microcomputer (μC21) 120. The image data of is added and the data for instructing the operation to be stored in the frame memory (II) 122 is set (S1).
28). If the variable N _E is not 3, S126 and S128
And skip to S130.

At S130, the microcomputer (μC2) 100
The data set by is the microcomputer (μC21) 120
Then, based on the data from the microcomputer (μC1) 1, it is determined whether the flash shooting in the preview shooting or the flash shooting in the electronic still shooting is performed (S132, S134). If none of the flash photography is performed, shake detection is performed based on G (green) component data input for each field, and shake correction control is performed based on this result (S140), and the return is performed. To do. On the other hand, in the case of flash photography in preview photography or electronic still photography, after the measurement is performed for a predetermined time, for example, 8 msec, a flash light emission signal is output (S136, S138), and S1
Move to 40.

Next, "PV control", "exposure correction" and "color correction" in the preview mode will be described with reference to FIGS.

FIG. 70 shows the "PV control" subroutine. First, it is determined whether or not a signal indicating the end of shooting in the preview mode has been input (S180), and if the shooting in the preview mode has not ended (N in S180).
O), a flag PVF indicating the preview mode
Is set to "1" (S182), the exposure control of "exposure control I" described above is performed (S184), and then the process returns. If shooting in the preview mode is completed (S
If YES in 180), the flag PVF is reset to "0" (S186), and the process returns.

FIG. 71 is a subroutine showing "exposure correction". First, it is determined whether or not the exposure correction amount with the flash light input from the microcomputer (μC1) 1 has changed from the previously input exposure correction value (S19).
0).

If the exposure correction value has changed (YES in S190), the image of the address of (N _IL +3) in the memory with respect to the light emission number N _IL in the multi-flash photography is displayed, and the exposure correction value for that light emission number changes. Amount ΔEV
Data for correcting only _FL is set (S192). If the exposure correction value has not changed (NO in S190), S192 is skipped.

Subsequently, it is judged whether or not the exposure correction amount with the constant light input from the microcomputer (μC1) 1 has changed with respect to the previously input exposure correction value (S19).
4). If the exposure correction value has changed (YES in S194
S), data for correcting the image data in the frame memory (III) 123 by the variation amount ΔEV _AMB is set (S196), and the process returns. If the exposure correction value has not changed (NO in S194), the process skips S196 and returns.

FIG. 72 shows the "color correction" subroutine. First, the blue and red correction data ΔB and ΔR are initially set to “0”, and the correction amounts ΔB ₂ and ΔR ₂ to be corrected are obtained based on the color correction data ΔB _C and ΔR _C input from the camera body 20 side. (S200).

Subsequently, it is judged whether or not the photographing mode is silver salt still (S202). If the photographing mode is not silver salt still (NO in S202), the color correction data ΔB ₁ ,
ΔR ₁ is set to “0” (S204), S206
Move to This is because it is not necessary to correct the color temperature of the film unless the film is photographed on a silver salt film. On the other hand, if the shooting mode is silver salt still (S202)
YES), skip S204 and move to S206.

In S206, it is determined whether the type of the loaded film is daylight, tungsten, or black and white. If the loaded film is a black and white type (S2
At 06, WB), the control data for deleting the color information is created (S208), and the process returns.

On the other hand, if the loaded film is of the tungsten type (tungsten in S206), the color correction amounts ΔB ₁ and ΔR ₁ are the correction amounts ΔB corresponding to the tungsten type.
_{If t} and ΔR _t are set (S210, S212), and if it is a daylight type (daylight in S206), the color correction amounts ΔB ₁ , ΔR ₁ are the correction amounts Δ according to the daylight type.
B _d and ΔR _d are set (S214, S216).

Subsequently, the overall correction amount ΔB (= ΔB ₁ + ΔB ₂ ) for blue is set from the correction amounts ΔB ₁ and B ₂ (S218), and the overall correction amount ΔR ₁ and R ₂ for red is set. The correction amount ΔR (= ΔR ₁ + ΔR ₂ ) is set (S220). Then, the control signal i is generated according to the set correction amounts ΔB and ΔR (S222), and the process returns.

Next, "display control I" will be described using the subroutine of FIG. First, the microcomputer (μC
1) It is determined based on the data input from 1 whether or not recording is in progress (S230). If recording is in progress, the process returns as it is. If not, a flag indicating that the still image display mode is set. It is determined whether DPIF is set to "1" (S232).

If the still image display mode is set (D
PIF = 1), the flag DPIF is reset to "0" (S234), and then data for switching the input destination of the data instructing display from the frame memory (II) 122 to the frame memory (I) 121 is set. After that (S236), the process returns.

On the other hand, if the still image display mode is not set (DPIF = 0), the flag DPIF is set to "1" (S238), and subsequently, the input destination of the data instructing the display is the frame memory (I ) 121 to the frame memory (II) 122 is set (S240), and the data necessary for display is further created (# 242), and then the process returns.

Here, the data creation processing will be described using the subroutine of FIG. First, the microcomputer (μC
1) Based on the data input from 1, it is determined whether or not the MFL shooting mode is set (S250).

If it is the MFL photographing mode (Y in S250)
ES), the image data stored after the frame memory (III) is added according to the number of flashes N _MF (the number of times of shooting) of the multi-flash, and the image data to be output to the frame memory (II) 122 is set (S252). ), Return. For example, if the number of emission times N _MF is 2, the image data (frame memory (II
(Image data of I)), and image data to be output by adding three pieces of image data of the image data (frame memories (IV) and (v)) whose source is only the flash light captured at each flash emission. Is set.

If it is not the MFL shooting mode (NO in S250), it is further determined whether or not it is the normal flash shooting (S254), and if it is the normal flash shooting (S254).
If YES in 254), the image data in the frame memory (III) and the image data in the frame memory (IV) are added and the image data output to the frame memory (II) 122 is set (S256), and the process returns. If it is not normal flash photography (NO in S254), the image data in the frame memory (III) is the frame memory (II) 122.
Is set as image data to be output to (S25
8) Return.

The set image data is output to the image processing microcomputer (μC21) 120, and the microcomputer (μC21) 120 performs predetermined image processing based on the image data.

Next, "display control II" will be described using the subroutine of FIG. First, it is determined whether or not the continuous shooting mode is set (S260). If the continuous shooting mode is not set, the process returns. If it is the continuous shooting mode, it is further determined whether or not a change operation has been performed, that is, whether or not the switch S _DPUP has been turned on (S262).

If the switch S _DPUP is not turned on from off (NO in S262), the flow returns and the switch S
_{If DPUP} is turned on from off (Y in S262)
S), the currently displayed read address of the internal memory 129 is increased, and addressing is performed (S26).
4). Then, the display switching data for transferring the image stored in the designated address of the internal memory 129 to the frame memory (II) 122 is set (S2).
66), then return. In addition, frame memory (II) 1
While inputting the image data from the internal memory 129, 22 outputs this image data to the monitor 47 and displays it.

The control operation of the microcomputer (μC21) 120 has already been described in connection with the microcomputer (μC2) 100, and therefore its explanation is omitted. Microcomputer (μ
In C21) 120, based on the input data from the microcomputer (μC2) 100, the above-described insertion of the character into the monitor 47, addition / subtraction of image data, color conversion, control of the frame memories 121 and 122, display switching control, Control of the adder circuit 124, control of the switch 125, storage control of the IC card 51, control of the internal memory 129, etc. are performed.

Further, in the calculation between the image data of the memory III and after, and the calculation of the input data and the image data of the frame memory (III), the calculation result is always the frame memory (I
I) is input to the monitor 47 and is automatically output from the frame memory (II) to the monitor 47 and displayed after the image calculation processing is completed.

The monitor display in the exposure correction process in the MFL shooting mode will be described with reference to FIGS. 76 to 80.

FIG. 76 is a diagram showing an example of a monitor image displayed on the monitor 47 in the MFL photographing mode.

The monitor image shown in the figure is the one displayed on the monitor 47 by turning on the still image display instruction switch S _DPI at the end of the preview process in the MFL photographing mode, and displays the steady light and the flash light. It is an image with consideration. In the same figure, the regions covered by diagonal lines ~ indicate the parts illuminated by the flashes FL1 to FL3, respectively. Note that the flash light actually wraps around the portions other than the shaded portion, but here, for convenience of explanation,
The portions mainly illuminated by the flashes FL1 to FL3 are shown.

77 to 79 are images obtained by extracting only the region from FIG. 76, respectively, in the flash FL1 to FL.
3 shows the parts illuminated by 3 respectively.

In the exposure correction processing shown in FIG. 71, for example, the flash No. 1 (Main flash FL
When the exposure correction is performed on 1), the exposure correction is performed on the area shown in FIG. For example, if the exposure correction value is +1 EV, the monitor image is as shown in FIG.
The exposure amount of the portion (individually, the face portion of the person) shown in the area is corrected to be doubled, and the flash No. is displayed at the right end of the screen. Display showing (N _IL ) and exposure correction value ΔEV _FL (1 (N _IL ), +1.0 (ΔEV
_FL )) is displayed. The exposure correction area of each flash shown in FIGS. 77 to 79 is not displayed.

Next, the control of the microcomputer (μC _FL ) 600 of the main flash FL1 will be described. When the power switch (not shown) of the main flash FL1 is turned on, the main flowchart shown in FIG. 81 is executed. Is set (# F2).

Emission No. 82 is set by executing the subroutine "light emission No. setting" shown in FIG. That is, it is determined whether or not the flash No setting switch S _FLN has changed from off to on (# F20), and if the flash No setting switch S _FLN is in the off state (# F20).
No), return, and if it has changed from off to on (YES in # F20), flash No setting switch S
The numbers "1" to "8" are changed according to the operation of the _FLN , and the light emission No. After ( _NFN ) is set (# F22), the process returns.

Subsequently, it is determined whether or not the MFL photographing mode is set (# F4). If the MFL photographing mode is set, the flag signal MFL is set to the high level (# F6), and the camera is further set. Microcomputer on the main body 20 side (μ
It is determined whether or not the light emission signal is transmitted from C1) 1 (# F8).

If the light emission signal is transmitted, the main flash FL1 to the other flash FLs should be emitted simultaneously.
A second wireless signal (light emission signal at the time of main light emission) is output to FL2 and FL3 (# F10) and the process returns to # F2. If no light emission signal is transmitted, the process returns to # F2. Also, #F
If the MFL shooting mode is not set in step 4, the flag signal MFL is set to the low level (# F12), #
Return to F2.

When data is output from the camera body to the main flash FL1 during execution of the main flow chart, the CPU (μC _FL ) 600 executes the flow chart of “data interruption” shown in FIG. Perform input processing.

First, the data transmitted from the camera body 20 side is fetched (# F30), and then the required data is output from the monitor side (# F32). Then, it is determined from the captured data whether or not the color temperature change mode is set (# F34). If the color temperature change mode is set, the transmissive color LCD 67 is further set to the mounting position. It is determined whether or not (the switch SD1 is on) (# F36).

If the transmissive color LCD 67 is not set to the mounting position (NO in # F36), the drive motor M is driven in the normal direction and the drive motor M is operated to set the transmissive color LCD 67 to the mounting position. The flag MOTF which indicates that it is in the middle is set to "1"(#F
38, # F40) and # F34.

On the other hand, when the transmissive color LCD 67 is set to the mounting position (YES in # F36), the "motor stop" subroutine shown in FIG. 84 is executed to drive the drive motor M.
Is stopped (# F42).

That is, in FIG. 84, first, it is determined whether or not the flag MOTF is reset to "0"(# F70), and if the flag MOTF is reset to "0", the process immediately returns and the flag is reset. If MOTF is set to "1", the drive motor M is stopped (# F72), the flag MOTF is reset to "0"(# F74), and the process returns.

Returning to FIG. 83, after the drive motor is stopped, the color adjustment of the transmissive color LCD 67 is performed based on the color temperature data input from the camera body 20 (# F4

If the color temperature change mode is not set in # F34, it is determined whether or not the transmissive color LCD 67 is set in the mounting position (whether the switch SD1 is on) (# F46). If the transmissive color LCD 67 is set to the mounting position (YES in # F46),
The drive motor M is reversely driven to reset the transmissive color LCD 67 to the retracted position, and the transmissive color L
The drive of the CD is stopped (# F48, # F50), the flag MOTF is set to "1"(# F52),
Return to # F34.

On the other hand, if the transmissive color LCD 67 is not set to the mounting position (NO in # F46), whether the transmissive color LCD 67 is reset to the retracted position (switch SD21 is on) or not is determined. It is determined (# F54). If the transmissive color LCD 67 is reset to the retracted position (YES in # F54), the driving of the drive motor M is stopped (# F56), the process proceeds to # F58, and if it is not reset to the retracted position (# (NO in F54), skip # F56 and go to # F58.

In # F58, it is determined whether or not the MFL shooting mode is set based on the data transmitted from the camera body 20 side. If the MFL shooting mode is not set (NO in # F58), # Return to F34, MF
If the L shooting mode is set (YES in # F58)
S), after executing the "multi-flash" subroutine to perform multi-flash emission processing, the process returns to # F34.

85 and 86 show the "multi flash".
Is a subroutine of. When the "multi-flash" subroutine is called, it is first determined based on the data transmitted from the camera body 20 whether or not the preview shooting is instructed (# F80), and the preview shooting is instructed. In this case (YES in # F80), the flag PVF indicating the preview shooting is set to "1"(# F82). Then, it waits until a light emission signal is transmitted from the camera body 20, and when this light emission signal is received (YES in # F84), the timer built in the microcomputer (μC _FL ) 600 is reset and then started. (# F86).

Subsequently, based on the data transmitted from the camera body 20, it is judged whether or not the number of times N _{PV of the} preview is taken is 1 (# F88), and if N _PV ≠ 1 (# F88). No), the first wireless signal is generated according to the number of shooting times N _PV (≧ 2), and then the first wireless signal is output to the flashes FL2, FL3 (#
F90, # F92). On the other hand, if N _PV = 1 (# F8
8 is YES), a light emission signal is output to the light emission circuit 605 (# F94).

Subsequently, in # F96, it is determined whether or not the light emission stop signal from the camera body 20 side is received, and if the light emission stop signal is not received (NO in # F96), 5

Then, in # F106, it is judged whether or not the number N _MF of light emission of the flash matches the number N _{PV of} photographing,
If N _MF ≠ N _PV (NO in # F106), the process returns to # F84 and the above flash emission process is continued, and N _MF = N
If it is _PV (YES in # F106), the process returns.

If preview shooting is not instructed in # F80, it is determined whether or not the flag PVF is set to "1"(# F108). If the flag PVF is reset to "0" (NO in # F108),
If the flag PVF is set to "1" (YES in # F108), the camera body 2

In # F114, it is determined whether or not the exposure correction mode is set based on the data transmitted from the camera body 20 side. If the exposure correction mode is set (YES in # F114), the exposure is performed. The flag EVCF indicating that the correction mode is set is set to "1"(# F116), and the process returns.

On the other hand, if the exposure correction mode is not set (NO in # F114), it is further determined whether or not the flag EVCF is set to "1"(# F11).
8) If the flag EVCF is reset to "0" (NO in # F118), the process returns, and if the flag EVCF is set to "1" (YES in # F118),
The value N _ILF is set to “2” as the process immediately after exiting the exposure compensation mode (# F120).

(F130) and returns.

FIG. 87 shows a subroutine of "light emission amount calculation". When the "light emission amount calculation" subroutine is called, first, the data (charge accumulated in the capacitor C30) monitored by the light emission amount monitor circuit 606 is taken into the microcomputer (μC _FL ) 600 (# F140), and from this data The light emission amount of the main flash FL1 is calculated (# F142).

Subsequently, the light emission control value at the time of main light emission is calculated by correcting the above calculation result based on the data of the above exposure correction amount (ΔEV _FL ) (# F144). Then, this calculation result is output as the V _ref signal (# F146) to set the variable reference voltage V _ref that determines the output timing of the light emission stop signal during the main light emission, and the process returns.

Next, referring to the wireless signal shown in FIG. 25, the flash FL when the wireless signal is received

The light emission of the xenon tube 65 is continued until the light emission stop signal (E signal portion of the first wireless signal) is received (# F158), and when the light emission stop signal is received (YES in # F158), A light emission stop signal is output to the light emitting circuit 605 through the light emission stop circuit 607 (# F16
0). Then, at this time, the light emission amount of the flash (charge accumulated in the capacitor C30) monitored by the light emission amount monitor circuit is held (# F162), and the process returns.

If the wireless signal is the second wireless signal (YES in # F164), the light emission setting number N _FN is transmitted in the C signal portion of the second wireless signal as in the case of the first wireless signal. It is determined whether or not it matches the set N number N _FNS of the flash that has been set (#
F166), if N _FN ≠ N _FNS (# F166 returns N
O), immediately returns, and if N _FN = N _FNS (#F
If YES at 166), the above-described light emission amount calculation process is performed (# F168), and then the process returns.

If the wireless signal is the third wireless signal (NO in # F164), a light emitting signal is output to the light emitting circuit 606 and the xenon tube 65 is emitted (# F17).

Since the light emission at this time is the main light emission, the light emission is based on the light emission control value (variable reference voltage V _ref set by the V _ref signal) set by the light emission amount monitored by the light emission amount monitor circuit 606. Light emission stop signal ST output from the quantity monitor circuit 606

In the above embodiment, CC is used as the image sensor.
Since a D (solid-state image sensor) type is used,
If the exposure time is longer than 1/60 seconds in still shooting mode, read the image obtained every 1/60 seconds and add it to the previous image to obtain a proper exposure. Also, obtain it every 1/60 seconds. Although the gain of the obtained image is digitally adjusted to obtain an appropriate exposure, a non-destructive image sensor shown in FIGS. 90 and 91 may be used instead. This type of sensor can read out data every 1/60 seconds while accumulating accumulated charge due to light. Therefore, if the read data is treated as an image and exposure is continued, the proper exposure can be achieved. You can get a still image.

FIG. 90 shows this non-destructive image sensor 30.
91 is a schematic sectional view showing the structure of 0, and FIG. 91 is its equivalent circuit. For convenience of description, the description will be given below based on the definition of Expression 1.

[0350]

[Equation 1]

The image sensor 300 comprises photoelectric conversion cells in a matrix, and the photoelectric conversion cells are arranged and formed on the n ₊ silicon substrate 301. Each cell has SiO ₂ , S
Element isolation region 30 made of i ₃ N ₄ or polysilicon
2 electrically insulates cells adjacent to each other.

Each cell has the following structure. An n ₋ region 303 having a low impurity concentration is formed on the n ₊ silicon substrate 301 by an epitaxial technique or the like, and a p region 304 is formed by doping a p-type impurity on the n ₋ region 301. Impurity diffusion is performed in the p region 304. The n ₊ region 305 is formed by the technique or the ion implantation technique.
P region 304 and n ₊ region 305 are the base and emitter of the bipolar transistor, respectively.

N ₋ region 3 in which each region is formed in this way
03, an oxide film 306 is formed, and a capacitor electrode 307 having a predetermined area is formed on the oxide film 306. The capacitor electrode 307 is sandwiched between the oxide film 306 and p
By applying a pulse voltage to the capacitor electrode 307 facing the region 304, the potential of the p region 304 in the floating state is controlled. Further, an emitter electrode 308 connected to the n ₊ region 305, an n ₊ region 311 having a high impurity concentration, and a collector electrode 312 for applying a potential to the collector of the bipolar transistor are formed on the back surface of the substrate 301.

Next, the basic operation will be described. First, it is assumed that the p region 304, which is the base of the bipolar transistor, is in the initial state of negative potential. Light 313 enters from the p region 304 side, holes of the electron-hole pairs generated by the incident light are accumulated in the p region 304, and the accumulated holes cause the potential of the p region 304 to be in the positive direction. Rises to (accumulation operation).

Then, a positive voltage pulse for reading is applied to the capacitor electrode 307, and a reading signal corresponding to the change in the base potential during the storage operation is output from the emitter electrode 308 in the floating state (reading operation). . However, since the accumulated charge amount of the p region 304 which is the base hardly decreases, the read operation can be repeated. In addition, p region 3
In order to remove the holes accumulated in 04, the emitter electrode 3
08 is grounded, and a positive voltage refresh pulse is applied to the capacitor electrode 307. By applying this pulse, the p region 304 is biased in the forward direction with respect to the n ₊ region 305, and the accumulated holes are removed.

When the refresh pulse falls, the p region 304 returns to the initial state of negative potential (refresh operation). Thereafter, the operations of accumulating, reading and refreshing are similarly repeated.

Furthermore, as another method of the exposure operation, the exposure is terminated in 1/60 seconds, and the AG
A gain of 1 is set in the C circuit 105 (AGC circuit 109
May be unnecessary), and it may be determined with this gain whether or not the exposure is in the proper range.

Within the proper exposure range, both moving images and still images are properly exposed. On the other hand, in this case, a still image shot on a silver halide film has a different degree of image shake due to a difference in shutter speed, so when the shutter speed becomes slow enough to cause image shake, An alarm display may be provided to notify the photographer to that effect.

As described above, according to the present invention,
A transmissive color liquid crystal display means is arranged in front of the flash light emitting means, and the color temperature of the flash light irradiated to the subject is controlled by controlling the emission color of the transmissive color liquid crystal display means.

As a result, it is possible to easily and easily obtain an artificial lighting effect for producing a shooting situation in flash photography.
