The data BV _C is memory address 43 _H of the RAM.

 FIG. 12 is a flowchart showing AF control.

Referring to the figure, first, it is determined whether or not the switch S1 is turned on (# 500). When the switch S1 is not turned on, the process returns. When the switch S1 is turned on, the switch provided on the lens is determined.
A routine for determining the AF mode by turning on the SQ is executed (# 502). In this embodiment, the focusing control is usually performed by one-shot AF, the focus detection is performed in a selected focus detection zone (spot, middle, wide... Will be described later), and the focus lock control is not performed. It has become. Therefore, when the switch SQ provided on the lens is turned ON, continuous AF, spot AF, and focus lock can be performed for each of the above-described controls. switch
When SQ is turned ON, Which control of these is performed, and is a memory (for which the b _6, b ₇ of RAM addresses 09 _H, described below with reference to FIG. 39 ) Determined based on the data.

FIG. 13 is a flowchart showing a routine for determining the AF mode by the switch SQ.

In the figure, first, it is determined whether or not the switch SQ is ON (# 590). If it is ON, a flag SQF indicating that the switch SQ is ON is set (# 595). In the method described below, the continuous AF mode, determines the spot AF mode, the data of b ₆ b ₇ of the selected mode 09 _H from the focus lock mode (# 600), the continuous AF mode (C If AF) is selected, the content of the signal AFM indicating the current focusing control mode,
That is, the one-shot AF mode is substituted for the signal LAFM indicating the previous focusing control mode, and the content of the register AFM is set to the continuous AF mode (C · AF) (# 60).

If the selection mode is the focus lock mode (FL), a flag (FLK) indicating this is set, the movement of the lens is stopped, and the routine returns (# 625, 630).

When switch SQ is OFF, proceed to step # 635, and set flag
Determine whether SQF is set. If it is not set, it is determined that there is no operation on the switch SQ and the process returns. As if set switch SQ is turned OFF from ON, and resets the flag SQF, to return to the mode before the operation of the switch SQ is performed, from b _5, b ₆ of 08 _H to the selected mode Judge (# 640, 64
Five). If the continuous AF mode was selected, the focusing control mode (LAFM) before the switch SQ was turned on is changed to the current focusing control mode (AF
M) and return (# 650). If spot AF mode was selected, AF before switch SQ was turned ON
The zone (LAFZ) is set as the current AF zone (AFZ) and the process returns (# 655). If the focus lock mode has been selected, the flag (FLKF) is reset and the routine returns (# 660).

Returning to FIG. 12, when the subroutine of the ON of the switch SQ is completed, it is determined whether or not the AFEF flag is set, and if so, the AFM determines whether the AF mode or the one-shot AF is set. (# 505, 51)
0).

If it is one-shot AF (YES in # 510), the routine returns. If the flag AFEF is not set or is not the one-shot AF, the process proceeds to step # 515, where the integral data dump of the image sensor is performed, and the defocus amounts DF1 to DF5 of the focus detection areas 1 to 5 are calculated (# 515
~ 525). The focus detection areas 1 to 5 are arranged as shown in FIG.

Next, the AF zone is determined (# 530). If the zone is the first zone (spot), the control defocus amount (DF) is changed to the defocus amount (DF3) of the focus detection area 3.
(# 535). If the zone is the second zone (middle), the maximum defocus amount of the focus detection areas 2, 3, and 4 indicates the closest subject, and positive indicates the front focus and negative indicates the rear focus. Is set as the control defocus amount DF (# 540). If the zone is the third zone (wide), the maximum defocus amount in the entire focus detection area is set as the control defocus amount DF (# 545). After calculating the control defocus amount DF, the process proceeds to step # 550 (# 545). Then, it is determined whether or not the obtained control defocus amount DF is equal to or less than a predetermined amount. If the control defocus amount DF is equal to or less than the predetermined amount _CV , a flag AFEF indicating in-focus is set and the process returns (# 550, 55).
Five).

When the defocus amount DF exceeds the predetermined amount C _V (# 550
NO), it is determined by the focus lock flag FLKF whether or not the focus is locked (# 560). If the focus is locked (FLKF = 1), the process returns as it is. If the focus is not locked (FLKF = 0),
Resets the flag AFEF, determine the lens drive amount N is multiplied by the defocus amount DF defocus lens conversion factor K _L (which is memory address 22 _H of the RAM), performs a lens driving based on this Return (# 565 ~ 57
Five).

When the AF control is completed, the microcomputer μC controls the automatic program zoom APZ shown in FIG. 8 (# 205).

FIG. 14 is a flowchart showing a subroutine of this control.

First, determine the mode of APZ from the data of b ₆ b ₇ of OB _H (# 670). If the mode is OFF, return immediately. If the mode is P (program) mode,
Photographing magnification for the object distance D _V are predetermined,
Therefore, the focal length f is determined with respect to the distance D _V (# 675). It as an address the subject distance D _V, it is sufficient to have a focal length f based on photographing magnification as a memory such as a ROM table. Next, upper body mode If the imaging magnification .beta.1 as 1/60, to obtain a focal length f as f = β1 · D _V from the .beta.1 and the object distance D _V (# 680). Full body mode If the photographing magnification β2 is 1/100, this photographing magnification β
Obtaining a focal length f as from the 2 and the object distance _{D V f = B2 · D V} (# 685). However, the object distance D _V is inputted from the lens (described later), are those memory address 23 _H of the RAM. Note that the focal length f obtained by the above calculation is
It is memory address 2B _H of RAM for the zoom lens drive.

After obtaining the focal length f in the above step, it is determined whether or not a flag APZF indicating the mode of the APZ is set (# 690). When the flag APZF is not set, the flag is set to set the variable N to 0, and after outputting the lens data, 1 is added to the variable N, the value is set to N, and the routine returns (# 695 to 710).

Here, the flow of lens data output will be described with reference to FIG.

First, data indicating that the data output mode from the camera to the lens set to b ₀ of 2A _H, the terminal CSLE the L level. First, SIO is performed once, and b _{0 of} 2A _H
Outputs data of ~b _7, then 2B _H, the data of 2C _H SIO
Is output twice, and the terminal CSLE is set to the H level to return (# 1690 to 1710).

Returning to FIG. 14, when the flag APZF is set, it is determined whether or not N = 5 (# 715). If N = 5, the process proceeds to step # 700. If N = 5, the process proceeds to step # 710, and the variable N is incremented by one. This means that if the zoom lens is driven every distance measurement, the zoom lens is always driven, and the feeling is not good.
This is for driving the zoom lens twice. Subsequently, based on the lens data output (2B _H ), the lens drives the zoom lens, and then returns to the flow of FIG. 8 (# 715). The zoom drive motor is provided on the lens side (see FIG. 46).

When the control of the APZ is completed, a routine for reading the film sensitivity SV from the DX-coded film is executed.

 FIG. 16 is a flowchart showing this routine.

First, read the film speed SV from the film, is set to b ₀ ~b ₅ of the data of the film sensitivity SV 08 _H. The correction amount ΔSV stored in b _{0 to} b ₄ of 09 _{H in} this film sensitivity SV
(Described later) to obtain a new film speed SV (# 92
5-935). Then, b ₀ ~b ₇ of the film sensitivity SV 44 _H
(For output to the card) (# 937) and return to FIG.

Returning to FIG. 8, the routine for card communication II and Fl data communication I is performed (# 210, 215).

FIG. 17 is a flowchart showing a routine of card communication II. First, data indicating the communication mode II of 40 _H b ₀ b
It is set to _1, and outputs the 40 _H of the data is performed once serial communication terminal CSCD as L level. Next, serial communication is performed three times, the terminal CSCD is set to the H level, and the process returns (# 720 to 735). The three serial communication described above, the memory information in the address 43 _H to 45 _H of RAM, i.e., photometric data BV _C, film sensitivity SV, ON / OFF (described later) of the card function, release of presence / absence ( S2 ON / OFF),
The exposure shift amount and the number of shots (described later) of the auto bracket card, and the ON / OFF function data of the switch S1 are output from the camera to the card. The description of the communication I of the FL data is omitted because it has already been made (FIG. 7).

Returning to FIG. 8, when the FL data communication I is completed, a flash mode routine is executed next. This is to determine the combination of use of the built-in flash and the external flash depending on the ON / OFF state of the switch of the built-in flash and the presence / absence of the mounting of the external flash.

FIG. 18 is a flowchart showing a subroutine for determining this combination.

First, it is determined whether or not the light-emitting switch S _INF of the built-in flash is turned on. If the switch S _INF is turned on, the terminal BSCN is set to the H level to start boosting, and whether the external flash is mounted is determined. It determines based on the input data _{(35 H) (# 735,740)} . When the flash external is mounted, whether or not the light-emitting switch of the flash ON mode is determined based on the b ₄ data 0E _H (# 74
Five). When the switch is in the ON mode (04 _H b ₄ = 1),
The flash mode FLM is set to "0" (both are ON) and the process returns (# 750). When the flash is external not mounted, or when the flash switch external is OFF mode (b ₄ = 0 in 0E _H), the flash mode FLM
Is returned as "1" (only built-in flash) (# 755). When the built-in flash switch is OFF, the terminal BSCN is set to the L level to stop the boosting, and it is determined based on the input data whether the external flash is mounted (# 760, 765). When the external flash is mounted, it is determined whether the light emitting switch is in the ON mode. When the external flash is ON, the flash mode FLM is set to “2” (only the external FL) and the process returns (# 770). , 77
Five). When no external flash is attached or its switch mode is OFF, flash mode F
The process returns with LM set to "3" (no flash emission) (# 780).

Returning to FIG. 8, when the flash mode is determined, a routine for inputting exposure control data from the card is executed. FIG. 19 is a flowchart showing this routine.

First, it sets the data indicating the card communication III to b ₀ b ₁ of 40 _H, the terminal CSCD to L level and outputs it to the card information 40 _H from the camera (# 1030 to 1035).

Next, 3 bytes of data are transferred from the card to RAM address 4
Input to 9 _H to 51 _H, back to terminal CSCD to (# 1040,1045) FIG. 8 to return to the H level, performs exposure calculation (AE operation) and operation of the relative range of the flash (FL calculation) (# 225, 23
0).

FIG. 20 and FIG. 21 are flowcharts showing each of these subroutines.

First, in the AE calculation, the focal length data f obtained from the lens
Based on the (memory 21 _H), to obtain a camera shake limit speed TVf (# 800). The value is the reciprocal of the focal length. Then the exposure value EV calculated by _{EV = SV + BV C + AV} O, obtaining a control exposure value by adding the exposure correction amount ΔEV (# 810,815). However, AV ₀ is the open aperture value of the lens, which is memory address 20 _H of the RAM, also exposure correction amount ΔEV is memory b ₃ ~b ₇ of as described below, 03 _H. Next, it is determined AE mode from the 03 _H of b ₀ b ₁ data. In the case of the program (P) mode, since the photometric mode is the auto mode (see FIG. 11), it is determined whether or not the luminance difference ΔBV between the spot photometric value and the average photometric value exceeds 2, and the luminance difference is 2 if less calculates the sum EVf the camera shake limit speed TVf the open aperture value AV _0, compares the magnitude of the resulting control exposure value EV. If EV ≧ EVf, it is determined that no camera shake occurs, and the shutter speed TV and the aperture value AV are obtained from a predetermined program diagram based on the control exposure value EV, the flag FLF indicating flash emission is reset, and the process proceeds to step # 865. Go on (# 825-845). If the luminance difference exceeds 2 in step # 825, the backlight is set to the backlight state or step #
If EV <EVf in 835, it is determined that the possibility of camera shake is high, and the process proceeds to step # 850. Then, a flag FLF indicating that flash emission is necessary is set, the shutter speed TV is set to TV _X (1/125) for tuning, and the aperture value AV is obtained as AV = EV−TV, and the flow proceeds to step # 865 ( # 850-860).

If the AE mode is the shutter priority (S) mode, the aperture value AV is obtained by EV-TV, and the flash mode FLM is set to “3”.
It is determined whether or not a flash is not emitted. Mode is "3"
If not, the flow proceeds to step # 850 to perform control for flash emission, and if the mode is "3", the flow proceeds to step # 865 as flash non-emission (# 890, 895).

If the AE mode is the aperture priority (A) mode, the shutter speed TV and EV-AV are obtained, and it is determined whether or not the flash mode FLM is "3". If the mode is "3", the process proceeds to step # 865 immediately without flash emission (# 900, 905). On the other hand, if the mode is not "3",
The flash speed flag FLF is set with the shutter speed TV set as the tuning speed TV _X , and the process proceeds to step # 865 (# 91
0, 915).

If the mode is the manual mode, that is, the M mode, it is determined whether or not the flash mode FLM is “3”. If the mode is “3”, immediately go to step # 865,
If the mode is not "3", the process proceeds to step # 915 (# 92
0).

In step # 865, b ₅ of 0C _H whether there is a card
In the judgment, if the card determines whether its function is ON at b ₆ of 0C _H (# 865,870). If the function is ON, the shutter speed (TV _CD … 4
9 _H), aperture value (AV _CD ... 50 _H), each shutter speed control (TV ... 01 _H), returns as the aperture value _{(AV ... 02 H) (#} 875,880). If there is no card, or if the function is OFF, return immediately.

Next, in FIG. 21, based on the first data input from the card, determines whether there is a flash off signal (51 _H b ₀₎ of, unless off, the flash mode FLM is "3" ( (No light emission) is determined (# 950, 952). If the flash mode is not "3", it is determined whether or not the flash mode is "1" (only the built-in flash is ON) (#
955). If the flash mode is "1", the shortest flash interlocking distance DVmin is calculated from the minimum light emission amount (IVmin) of the built-in flash (stored in the camera) as DVmin = IVmin + SV-AV, and the built-in flash maximum light emission From the amount (IVmax) (stored in the camera), the longest flash photography interlocking distance (DVmax) is calculated as DVmax = IVmax + SV-AV, and the process proceeds to step # 990 (# 980, 985). Incidentally, DVmin, DVmax are respectively memory b ₀ ~b ₆ of b ₁ ~b _6, 05 _H of 04 _H. If the flash memory is not "1" in step # 955, the process proceeds to step # 960. At this time, at least the external flash is attached and it is ON,
In this embodiment, if the external flash can emit light, priority is given to the external flash. That is, even if the built-in flash can emit light, the built-in flash is set as light emission inhibition. Therefore, in step # 960, the shortest interlocking distance DVmin of the flash is obtained from the minimum light emission amount IVmin 'input from the external flash by DVmin = IVmin' + SV-AV. H / L (H: light emission is possible up to the maximum light emission amount of the flash; L: 4 of the maximum light emission amount
The mode stage (EV) emitting allowed to under) determined by signal b ₀ of OE _H, if L mode, the maximum light emission amount minus 4 from the maximum light emission amount IVmax ', in step # 975 Go on (# 970). When it is determined in step # 965 that the mode is the H mode, the process proceeds to step # 975. In step # 975, the longest interlocking distance DVmax is obtained from the maximum light emission amount IVmax 'by DVmax = IVmax' + SV-AV, and a flag FL indicates whether or not flash light emission is necessary.
Judge from F (# 975, 990). Here, if the flash is necessary (FLF = 1), respectively in the "0" returns the b _7, 05 _H of b ₇ data 04 _H for the display OFF interlocking range (# 1005, 1010) . If the data from the card is in the flash off mode in step # 950, or if the flash mode FLM is "3" in step # 952, or if it is determined in step # 990 that no flash emission is required (FLF = 0), all the processing proceeds to # 1015, turn off the display of the interlocking range (not performed) Subeku 04 _H of b
_7, 05 respectively set b ₇ of _H and then returns (# 1015,10
20).

After the completion of the FL calculation, the process returns to FIG. 8, and data for displaying on the display unit DISP is output to the display control circuit DISPC (# 240) (see FIG. 6). And release switch S2
It is determined whether or not is turned on (# 245). If the switch is ON, among the data inputted from the card, it determines whether there is a release prohibition data (51 _H
Determining in the b ₁ signal) (# 247). If there is no release prohibition data, it is determined whether or not a flag AFEF indicating focusing is set (# 250). If set
Determining based on whether a self-mode 07 _H of b ₁ b ₂ data. If the mode is the self mode, wait for about 10 seconds. If the mode is not the self mode, skip step # 260 and proceed to step # 265 (# 255, 260). And after performing exposure control AE, 1 frame winding of the winding routine determines whether the continuous shooting mode 07 _H of b _1, b ₂ b _2. If it is not in the continuous shooting mode, the process waits until the shooting preparation switch S1 is turned off, and if it is turned off, returns (# 265 to # 280). In step # 275, if it is a continuous shooting mode, it is determined whether or not the mode is the low-speed continuous shooting mode (# 285). If the mode is the low-speed continuous shooting mode (three frames per second), the process proceeds to step # 185 after waiting for 300 msec. If not, the process immediately proceeds to step # 185 because the mode is the high-speed continuous shooting mode. If the release switch S2 is OFF in step # 245, or if there is release prohibition data from the card, or if it is not in focus in step # 250 (AFEF = 0), the routine returns immediately.

If it is not the level and the second curtain sync, the terminal STP is set to the L level, and the process proceeds to step # 1095. Step # 1095 in manual (full emission) or Auto (dimming) or a 0E _H b ₂
If it is automatic, the terminal STP is set to H, and if it is manual, the terminal STP is set to L, and the process proceeds to step # 1110 (# 1095 to 1105). At step # 1110, it is determined based on whether the spot dimming b ₃ data 0E _H. In the case of spot dimming, the terminal SP is set to L, and in the case of non-spot dimming, the terminal SP is set to H level and the process proceeds to step # 1125 (# 1110-
1120). In step # 1125, it is determined from the flag FLF whether or not flash emission is necessary. If the flash emission is required (FLF = 1), the terminal LE is set to H, and if the flash emission is not required, the terminal LE is set to the L level, and the process proceeds to step # 1140 (# 1125 to 1135). In step # 1140, it is determined whether or not the flash mode is "1": internal flash ON, external flash not attached or OFF. Mode is "1"
If it is, the terminal INFL is set to the H level, and if the mode is not "1", the process returns as the L level (# 1140 to 1150). The description of each terminal will be described later with reference to FIG.

By the way, when data is output to the display, the display control circuit DI
The SPC performs the display shown in DP-1 to DP-16 on the display unit DISP based on the input data, but it is clear how the display is performed in the above description. The parts that are difficult to understand in the figure are mainly explained.

In the display of DP-1 and DP-1 ', when flash photography display dimming interlocking flash range is also the focal distance display is displayed when the lens is mounted, each 04 _H of b _7, 05 is determined by the data b ₅ of _H of b _7, 0D _H.

In the display of DP-2, the display of "CARD" is displayed only when a card is installed, and in the display of DP-3,
"FLASH" is displayed only when the flash external is mounted, it is determined by b ₅ each b of 0C _{H 5,} 0E _H.

The negative display of "BRAKT" or "SPORT" in DP-1 is displayed when a card is mounted and the function is ON, and has a switch configuration. That is, if the display is turned on while “BRAKT” is displayed, the data setting process required for the auto bracket shooting shown in FIG. 36 is performed directly.
When "SPORT" is displayed and turned on, the display of the call mode III (DP-4 in FIG. 2B) is performed.

Returning to FIG. 3, when the set routine of step # 45 is completed, a display data output subroutine (# 50) is performed, and the flow proceeds to step # 20.

If the call flag (call F) is not set in step # 40, the process proceeds to step # 55. When a flag (timer F) for reset start of timer counting is set, this flag is reset, the timer is reset and started, and the process proceeds to step # 70 (# 55 to # 6).
Five). Even when the flag (timer F) is not set in step # 55, the process proceeds to step # 70, and in # 70, it is determined whether the timer has elapsed for 5 minutes, and if it has elapsed, halt control is performed. Halting (# 70, 75). 5
If the minute has not elapsed, the data setting subroutine (# 76) is executed, the switch S1 ON subroutine is executed, and the process returns to step # 10. This data setting subroutine is performed by an up / down switch and a card function change _Sc6 switch provided on the camera body, and the shutter speed, the aperture value, and the card mode are changed (# 76).

FIG. 42 is a flowchart showing a subroutine for this setting.

The display at this time is, for example, DP-1, DP- shown in FIG. 2B.
1 'is displayed, and the part of the negative display that is displayed as "SPORT" or "BRAKT" is a switch, it is displayed when there is a card and the mode of the function is ON. You. First, in this flow, the switch
It is determined whether _Sc6 is ON. If it is not turned on, it is determined whether or not a flag _SCNF indicating that the switch is turned on is set. If not, the process proceeds to step # 390. When the flag _SCNF is set, it is determined that the switch _Sc6 has been changed from ON to OFF, and the process proceeds to Step # 387 to perform various settings. Subsequently, it is determined whether or not the mode is the bracket mode. If the mode is the bracket mode, the subroutine AEB is executed. If the mode is not the bracket mode, the call mode III is executed and the process returns (# 386 to # 386).

If step _Sc6 is ON in step # 379, the process proceeds to step # 380. Step # 380 card is mounted in (b ₅ of 0C _H), and if the card function is ON (b ₆ of 0C _H), the flow proceeds to step # 382, determines whether the seated card bracket card to (b ₅ of 0B _H). If a bracket card 00 b ₀ ~b ₇ of _H sets data (10H) as bracketing mode, sets the data (14H) as the call mode III when the bracket card is not mounted. Subsequently, a flag _SCNF indicating that the switch _Sc6 has been turned on is set and the routine returns (# 37).
9-385). On the other hand, if the card is not mounted or the card function is OFF, the routine returns.

If the process has proceeded to step # 390, it is determined in step # 390 whether the current AE mode is the P mode (# 39).
0). The determination of the AE mode (is the same except for the following P mode) is performed on the basis of b _0, b ₁ of 03 _H. If the mode is the P mode, the process returns. If it is not the P mode, it is determined whether or not the switch _SMI is turned on (mode I) (# 391). In mode I, in the M mode, the shutter speed is changed by operating the up / down switches S _UP and S _DN .
The aperture value is changed by operating the up / down switches S _UP and S _DN . If it is not mode I in step # 391, it is determined whether or not the mode is the S mode (# 392). In the S mode, if the up switch S _UP is turned on, the shutter speed is set to TV = TV + 0.5, and if the down switch S _DN is turned on, TV = TV−0.5, and the routine returns (# 400 to 415). If no switch is operated, the routine immediately returns.

If it is not S mode in step # 392, that is, if it is M mode or A mode, the up switch S _UP ,
In response to the operation of the down switch S _DN, returns as each AV = AV + 0.5 AV = AV -0.5 the aperture value, immediately returns if any of the operation (# 420-435).

In step # 391, if the mode is I, it is determined whether the mode is the M mode. If in M mode, step # 400
The program proceeds to step # 392 to change the shutter speed. If the mode is not the M mode, the process proceeds to step # 392 (# 395).

Next, the dimming circuit and the built-in flash circuit will be described with reference to FIG.

First, a circuit related to data communication will be described. Terminal
When the H level signal is output from the CSFL for an instant, the OR circuit
This signal is output from OR2 to the flash. Next, terminal S
The data communication clock is output from CK and the OR circuit OR2
Connected to the flash via When data is output from the camera in synchronization with this clock, the terminal SO
The data is output from the UT to the flash via the OR circuit OR1 and the input / output switching circuit (I / O switching). At this time, the input / output switching circuit has been switched to the output side. At the time of data input, the data is input from the terminal ST2 to the terminal SIN via the input / output switching circuit.

Next, the dimming circuit will be described. The light receiving element SPC1 connected to the dimming circuit LAC dims the area around the shooting screen, and the light receiving element SPC2 dims the center of the shooting screen. And the light receiving element SP
When the switch SP connected to C1 is ON, dimming (wide dimming) is performed in both ranges, and when the switch is OFF, spot dimming is performed based only on the center of the shooting screen. The dimming circuit LAC can change the dimming amount according to the film sensitivity based on a signal obtained by changing the film sensitivity data to analog. From the terminal STP, an H-level signal is output in the auto mode based on whether or not to perform dimming (or not in the auto mode).
When the amount of light received by the light receiving element reaches a predetermined level, an H level stop signal is output from the terminal STP of the dimming circuit LAC and transmitted to the flash via the AND circuit AN1, the OR circuit OR1, and the input / output switching circuit. . The signal is sent from the AND circuit AN1 to the terminal STP of the light emission control circuit ECC1 to the built-in flash.

Built-in flash, booster circuit BS1, rectifier diode RD
1, a light emission capacitor MC1 and a light emission control circuit ECC1 for stopping light emission of a flash.

When the front curtain run is completed, the X contact turns on and this signal
The signal reflected by the inverter IN1 and output to the AND circuit AN3 and delayed by the delay circuit DL1
Output to N2. Terminals ST are connected to AND circuits AN2 and AN3.
From T, a signal indicating whether or not rear curtain sync light is to be emitted (H level signal for rear curtain sync light) is input. A light emission signal is output from the AND circuit AN3 to the AND circuit AN4. A signal for enabling / disabling light emission is input / output from the terminal LE to the AND circuit AN4. When the signal is unavailable, an L level signal is input. If yes, an H level signal is input, the AND circuit AN4 is opened, and a light emission signal is input to the external flash. This signal is also input to the AND circuit AN5. The AND circuit AN5 outputs a light emission enable / disable signal relating only to the built-in flash from the terminal INFL, and if light emission is not possible, that is, if an H level signal is output from the terminal INFL, a light emission signal is output.

 FIG. 44 is a circuit diagram of the external flash.

In the figure, the flash circuit includes a battery E _FL , a diode D3, a backup capacitor BUC, a microcomputer μC2 for controlling flash, a booster circuit BS2, a light emitting capacitor MC2, a rectifier diode D2, and a light emission control circuit ECC2.

FIG. 45 is a flowchart showing the operation of the microcomputer μC2.

Hereinafter, the operation will be described with reference to FIG. Terminal ST
From 1 45, the interrupt shown in FIG. 45 is executed. First, interrupts to this flow are prohibited, and data communication is performed with the camera to obtain 1-byte data (RAM address 3
_0H data) (# FL-5, 10). At this time, a transfer clock is input from the terminal ST1, and data is input from the terminal ST2 in synchronization with the input. At this time, since an “L” level signal is input to one input of the AND circuit AN6 from the terminal STEN of the microcomputer μC2, the light emission control circuit ECC2
Signal does not reach. Based on the data input to the terminal ST2, the microcomputer μC2 determines whether or not exposure control is to be performed.
5 _H ~37 content of _H) to output (# FL-15,20). Since the data content has already been described, the description is omitted here. Further, based on the input data, the ON / OFF of the flash is determined. If ON, the terminal BCN is set to H level to start boosting, and if OFF, the terminal BCH is set to L level to stop boosting. Return as possible interrupt (# FL-25-40).

If it is determined in step # FL-15 that the exposure control is to be performed, the terminal STEN is set to the H level, and the light emission stop signal from the camera is sent to the terminal STP of the light emission control circuit ECC2 via the OR circuit OR3 and the AND circuit AN6. In addition to enabling inputting, it waits for the X contact to turn on, and when it turns on, starts the timer (# FL-45 to 55). Based on the input data, "H / L"... "H" determines that maximum light emission is possible, "L" determines that light emission of 1/16 of the maximum light emission amount is possible, and if not "L", step # Proceed to FL-75. If "L", wait until T = TA (this is the time when the light emission amount becomes 1/16), and if T = TA, stop emission from terminal STP. And the process proceeds to step # FL-75. Step #
The FL-75 waits for a certain period of time, sets the terminal STEN to the L level, and then enters the halt state with the interrupt enabled (# FL-75, 8
0, # FL-40).

FIG. 46 is a circuit block diagram of the lens, and FIGS. 47 and 48 are flowcharts of the microcomputer μC3 for controlling the operation of the lens.

 Hereinafter, the operation will be described with reference to the drawings.

When an L level signal is input from the camera to the terminal CSLE, the interrupt operation shown in FIG. 47 is executed. First, the data of the RAN address 0A _H 1 byte input from the terminal SIN in synchronization with the clock input terminal SCK (# L-5). Subsequently, it is determined whether or not the mode is the data output mode based on the input data. In the output mode, 5 bytes of data are output from the terminal _SOUT based on the clock input from the camera, and then zoom control (Z control) is performed (# L-
10, 20).

To explain this zoom control with reference to FIG. 48, based on the data inputted from the camera (the address 2C _H of RAM), and determines whether the APZ mode, focal length data input from the camera if APZ mode (RAM address 2B _H )
, The focal length f is controlled, and the process returns.
If the mode is not the APZ mode, control of the tele side zoom and the wide side zoom are performed in accordance with the operation of the tele side zoom switch S _ZT or the wide side zoom switch S _ZW , respectively, and the routine returns (# L-40 to 65).

Control of the zoom, the driving direction and the start of the zoom performs by outputting a signal to stop the zoom driving circuit Z _CN, zoom drive circuit based on the inputted signal, and drives the motor for the zoom lens drive . The control to the predetermined focal length is performed by inputting a signal from the zoom encoder Z · EN indicating the current focal length.

If it is not the output mode in step # L-10 of FIG. 47 (NO in # L-10), two bytes of data (RAM addresses 2B _H , 2C _H ) are input from the terminal SIN (# L-25). .
Based on the input data, it is determined whether the power of the camera is ON or OFF. If the power is ON, the process proceeds to step # L-20. If the power is OFF, the camera is assumed to be OFF and the zoom is stopped.
The microcomputer μC3 stops its operation (# L-35).

In Figure 46, the encoder DVEN outputs a signal indicating the object distance D _V where that focused lens. This data is output to the camera. Further, the zoom control circuit _ZCN has specific power supply lines (V _CC , GND2). Others have conventional power supply lines (V _CC , GND1).

FIG. 49A to FIG. 49C are flowcharts showing the control performed by the card in two types of cards, a sports card and a bracket card.

First, when an L-level signal is input from the terminal CSCD of the camera, the interrupt control shown in FIG. 49A is executed. 1-byte data (RAM address _40H ) is input to the terminal SIN in synchronization with the clock input from the camera terminal SCK (# CD-
5). If the mode is mode I (corresponding to communication I on the camera side) based on the input data, data indicating the type of the card is output by 1 byte (RAM address _41H ) and the process returns (# CD-10, 15). If not Mode I, Mode II
(Corresponding to communication II on the camera side). If mode II, photometric data from the camera, data of film sensitivity, camera switch state and auto bracket of data such as signals 3 bytes (RAM address 43 _H to 4
_5H ) Enter and determine from the input data whether the card function is OFF. Return if card function is OFF, return to O
If N, a subroutine exposure calculation is performed and a halt state is set (# CD-20 to # CD-20). Otherwise mode II, as a mode III (corresponding to the communication III of the camera side), the shutter speed TV _CD, an aperture value AV _CD and camera control data a total of 3 bytes (address RAM 49 _H to 51 _H) Output And return (# CD-40). This control is the same for both sports cards and auto bracket cards.

FIG. 49B shows a sports card exposure calculation subroutine.

First, the exposure value is calculated as EV = BV _C + SV based on the information input from the camera. Based on the exposure value, a shutter speed TV _CD and an aperture value AV _CD are determined by a predetermined program. Set as output data to (#
CD-45, 50). Then, after setting whether or not to use the flash, prohibition of release, and whether or not continuous shooting is to be displayed in the table of FIG. 50, the process returns (# CD-55). Since this exposure program corresponds to a sports scene, it is a program that gives priority to a high shutter speed.

FIG. 49C shows an exposure calculation subroutine for an auto bracket card.

First, it is determined whether or not the shooting preparation switch S1 is ON based on information input from the camera. If the switch is ON, it is determined whether or not release prohibition data is set in the card. If it is set, the process returns to prohibition of photographing (# CD-57, 58). If the switch S1 is not ON, the release prohibition data is reset, and the process proceeds to step # CD-60 (# CD-59). Even when the release prohibition data is not set in step # CD-58, the process proceeds to step # CD-60. In step # CD-60, it is determined whether or not the release switch S2 is ON. If not, the exposure value EV is calculated by EV = BV _C + SV, and the variable N is set to 0. Further, control data is set as shown in the table of FIG. 50, a shutter speed TV _CD and an aperture value AV _CD are obtained from the exposure EV obtained above, and the data is returned as output data (# CD-63 to # CD-63). 80). Here, in this exposure program, the change in the shutter speed and the change in the aperture value are one-to-one with respect to the change in the exposure value. Note that the release prohibition data of the control data is not set here.

If the release switch S2 is ON in step # CD-60, the variable is set to N = N + 1, the shift amount ΔEV is calculated from the exposure shift amount input from the camera, and then the variable N is determined (# CD-85, 88,
90). If N = 1, the exposure value EV is calculated by EV = EV−ΔEV in order to overexpose by ΔEV, and it is determined whether or not the number of shot sets N _SET is 1, and if it is 1, release is prohibited. , And the process proceeds to step # CD-75 (# CD-95 to # CD-95). This means that whenever the flow reaches this step # CD-100, 1
This is because the photographing of the first sheet has been completed. That is, when the number of film shots is 1, the second shot is prohibited. If the number of shot sets _NSET is not 1, the process goes to step # CD-75 without doing anything. If N = 2, the exposure value EV is set to EV = EV + 2ΔEV so as to make the exposure under exposure by ΔEV, and the process proceeds to step # CD-75 (# CD-110, 115). N
If = 3, the exposure value EV should be overexposed by 2ΔEV
Is set as EV = EV−3ΔEV, and it is determined whether or not the number N _{SET of} shooting sets is 3. 3
If so, release-prohibited data is set; if not, the process immediately proceeds to step # CD-75 (# CD-120 to # CD-120).
30). If N = 4, the exposure value EV is set to EV = EV + Δ4EV so as to reduce the exposure by 2ΔEV. If N = 4, release prohibition data is set and the process proceeds to step # CD-75 (# CD-150). . Therefore, exposure shift shooting using the auto bracket card is performed in the order of proper exposure, ΔEV over, ΔEV under, 2ΔEV over, 2ΔEV under.
