In display data output, first, in order to indicate to the display control circuit DI SPC that it is the data communication mode, the terminal C3D is output.
ISP is set to L level (#130), serial data communication SIo is performed 16 times, that is, RAM address 0 is
The information from 08 to OFH is output to the display control circuit DI SPC (#135), and the terminal C3DISP is set to H level and returned (1130 to 140).

In the FL data communication system, first, the data indicating exposure control is reset (b1 of 30H → 0), the terminal C3FL indicating the data communication mode to the flash is set to L level for a moment, and the address 30. Perform serial communication sro once to output data of 4 (#14

Then, the input/output switching circuit (see FIG. 43) is switched to the input side. Next, serial communication SIO for inputting data from the flash is performed three times, the input/output switching is switched to the output side, and the process returns (#160.162). At this time, the data input from the flash is 35H to 37. This is the content that is stored in the memory.

Returning to FIG. 3, after completing the subroutine for turning on the main switch SM (#5), it is determined whether or not the shooting preparation switch S is turned on (#10). If it is turned on, the process proceeds to step #15. Next, the subroutine for turning on Sl is executed, and a flag S indicating that one of the switches Sc, to So9 has been turned on. Reset NF. Then set the timer flag (timer F) and step #10
Return to (#15, #20).

FIG. 8 is a flowchart showing the S, ON subroutine. In the figure, first, a flag (call F) indicating a call mode (described later) is reset (1180).

Next, lens data is input and communication with the IC card is performed (#185, 190).

FIG. 9 is a flowchart showing a subroutine for inputting lens data, and FIG. 10 is a flowchart showing the contents of card communication I.

In Fig. 9, first, input mode data is set (2
A M's bo"l)L, set the terminal C3LE to L level to indicate the data communication mode to the lens (#300.3
02). Then, serial communication is performed once to output 1 byte of data from the camera, followed by 5 serial communications to input 5 bytes of lens data, set terminal C3LE to H level, and return (# 305
~315). This lens data is at RAM address 20.
H~24. This is the content that is stored in the memory. Note that the focal length data is also stored in b0 to b7 of the OD for display to be described later.

In the card communication (2) shown in FIG. 10, data 408 indicating the communication (2) mode is stored. , b, set terminal C5CD to L level to indicate card data communication mode, and set data (40)I) indicating card communication to 1 for serial communication.
The data is output repeatedly, and then 1 byte of data is input from the card (#330 to 340). This data indicates the presence/absence of a card and the type of card, and is stored at address 41H of the RAM. Then, it indicates the end of the data communication mode (terminal C3CD is set to H level, and it is determined from the input data whether or not there is a card. If there is no card, the card presence data is reset. b5 of OC8
→0), if there is a card, set the card presence data (
OCH b5 → 1) and change the card type to OB
Set to b5 of H and return (#345-836
0).

After completing the card communication I routine, return to Fig. 8 and perform photometry and autofocus AF (#195.2
00). These operations will be explained based on FIGS. 11 and 12.

FIG. 11 is a flowchart showing the photometry routine. Note that photometry areas 1 to 9 are as shown in FIG.
They are arranged so that the shooting screen is divided into nine parts.

Returning to Fig. 11, first, from the photometric circuit LM, each area 1~
9 A/D converted digital data Bv1 to BV9 are input, and the set photometry mode is determined (#45
0.455). This determination is based on b of RAM address 07H.
This is done based on the data of 5 to b7. When in auto mode, the control photometric value B V c is the average of all photometric values, BVc = (BV1+BV2+・+BV9
)/9. Next, the deviation ΔBV between the control photometric value Bvc and the central photometric value BV5 is determined from ΔB V =B V c B V 5 and the process returns (#460, #465).

If the photometry mode is the first mode, the control photometry value Bv0 is determined as follows from the photometry values obtained from the photometry areas on the right side of the screen and the center of the screen.

In other words, BVc = (BV3+BV5+BV6+BV9)/
4 If the photometry mode is the second mode, it is average photometry, and the control photometry value BVo is B Vc = (B V 1 +...+B V 9)
/9 If the photometry mode is the third mode, the control photometry value B V c is determined as follows from the photometry values obtained from the photometry areas at the lower side and the center of the screen. In other words, BVc = (BV5+BV7+BV8+BV9)/4 If the photometry section is in the 4th mode, it is spot photometry, and BVc=BV5 If the photometry mode is in the 5th mode, the photometry values obtained from the photometry areas on the left side of the screen and in the center of the screen The control photometric value BV is determined from BV as follows.

In other words, BVo= (BV1+BV4+BV5+BV7)/4 (#470-495).

Note that data Bvo is stored at address 43H of RAM.

FIG. 12 is a flowchart showing AF control.

Referring to the figure, first determine whether the switch S1 is ON or not (#500). If it is not ON, return; if it is ON, the AF mode is set by turning on the switch SQ provided on the lens. A routine for determining is executed (#502). In this embodiment, focusing control is normally performed by one-shot AF, focus detection is performed in a selected focus detection zone (spot, middle, wide, etc. will be described later), and focus lock control is not performed. It is designed so that it will not be lost. 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-mentioned controls.

Which of these controls is executed when switch SQ is turned on is determined by b6 of RAM address 09H.
, b7 (this will be described later with reference to FIG. 39).

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

In the figure, first, it is determined whether the switch SQ is ON or not (#590), and if it is ON, the switch SQ is OFF.
Set the flag SQF indicating that the

Determine the mode selected from among AF mode, spot AF mode, and focus lock mode using the data in b6b7 of 09□ #600), and if continuous AF mode (C-AF) is selected, the current focusing Assign the contents of the signal AFM indicating the control mode, that is, the one-shot AF mode, to the signal LAFM indicating the previous focusing control mode, and set the contents of the register AFM to the continuous AF mode (C-AF) #60
5.610), return.

If the selected mode is spot AF mode (SPOT), the signal AFZ (b3b of 07H) indicating the current AF zone
4) is substituted into the signal ALFZ indicating the previous AF zone, and the content of the current AF zone signal AFZ is returned as the spot AF mode (#615.620).

If the selected mode is focus lock mode (F-L), a flag (FLK) indicating this is set, lens movement is stopped, and the process returns (#625.630).

When switch SQ is OFF, proceed to step #635;
Determine whether flag SQF is set. If it is not set, it is assumed that there is no operation on switch SQ and the process returns.

If it is set, it is assumed that switch SQ has changed from ON to OFF, and the flag SQF is reset, and switch SQ
To return to the mode before the operation was performed, determine the selected mode from b5 and b6 of 08)I (#640
．． 645). If the continuous AF mode has been selected, set the focusing control mode (LAFM) before the switch SQ was turned on to the current focusing control mode (AFM) and return (# 650
). If spot AF mode is selected,
AF zone (L A F
Z) as the current AF zone (AFZ) and return (#655). If the focus lock mode has been selected, the flag (FLKF) is reset and the process returns (#660).

Returning to FIG. 12, when the subroutine for turning on the switch SQ is completed, it is determined whether or not the flag AFEF indicating focus is set, and if it is set, the AFM determines whether the AF mode or one-shot AF is set. The determination is made based on the signal (#505.510).

If it is a one-shot AP (YES in #510), return. If flag AFEF is not set or it is not one-shot AF, step #515
Proceed to step 2, perform an integral data dump of the image sensor,
Defocus amount DF1 to DF of each focus detection area 1 to 5
5 is calculated (#515-525). Note that focus detection areas 1 to 5 are arranged as shown in FIG. 52.

Next, the AF zone is determined ($530).

If the zone is the first zone (spot), the control defocus amount (DF) is set to the defocus amount (DF3) of the focus detection area 3 (#535).

If the zone is the second zone (middle), the maximum defocus amount in focus detection area 2.3.4 represents the closest subject, positive means front focus, negative means rear focus. The control defocus amount DF is
(#540). Zone is 3rd zone (wide)
If so, the maximum defocus amount of all the focus detection areas is set as the control defocus amount DF (#545). After calculating the control defocus amount DF, step #55
Proceed to 0 (#545). Then, it is determined whether the obtained controlled defocus amount DF is less than or equal to a predetermined amount, and if it is less than or equal to the predetermined amount Cv, a flag AFEF indicating focus is set and the process returns (#550.555).

When the defocus amount DF exceeds the predetermined amount Cv (#5
50 (NO), determine whether the focus is locked using the focus lock flag FLKF #560
), if focus is locked (FLKF=1), return as is.

If the focus is not locked (FLKF=0),
Reset the flag AFEF and set the defocus amount DF to the defocus lens conversion coefficient KL (RAM address 2).
2.4 (stored in memory) to obtain the lens driving amount N, the lens is driven based on this, and the process returns (#565 to 575).

After completing the above AF control, the microcomputer μC controls the auto program zoom APZ shown in Fig. 8 (#205).
.

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

First, the mode of APZ is determined from the data of b6b7 of OB (#670). If the mode is OFF, the process returns immediately. That mode is P (program)
If it is the mode, the imaging magnification for the subject distance Dv is determined in advance, and therefore the focal length f is determined for the distance Dv (#675). This is the subject distance D
It is sufficient to have a focal length f based on the imaging magnification in a memory such as a ROM table, with v as an address.

Next, for upper body mode (Hata), set the shooting magnification β1 to 1
/60, f=β from this β1 and subject distance Dv
Obtain the focal length f as 1·Dv (#680). In the whole body mode (Fu), the photographing magnification β2 is set to 1/100, and from this photographing magnification β2 and the subject distance Dv, f=82・
The focal length f is obtained as Dv (#685). However, the subject distance D7 is input from the lens (described later) and is stored at address 238 of the RAM. In addition,
The focal length f obtained by the above calculation is stored in address 2B)l of the RAM for driving the zoom lens.

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

Here, the flow of lens data output is shown in FIG. 15 and will be explained.

First, data 2A, i indicating that the camera is in the data output mode to the lens is inserted. and connect terminal C3L to
Let E be L level. Then, first perform SIO once and output the data of bo to b7 of 2A)I, then
After performing SIO twice and outputting the data of BH, 2C, terminal C3LE is set to H level and returns (#1
690-1710).

Returning to FIG. 14, when the flag APZF is set, it is determined whether N=5 or not (#715). If N=5, the process goes to #700, and if N=5, the process goes to step #710, where the variable N is incremented by 1. This is because if the zoom lens is driven every time the distance is measured, the zoom lens is constantly being driven, which does not give a good feel, so the zoom lens is driven once every five distance measurements. Next, based on the lens data output (28H), the lens drives the zoom lens, and then
Return to the flow shown in the figure (#715). Note that the zoom drive motor is provided on the lens side (see FIG. 46).

After the above APZ control 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 sensitivity SV from the film, and read the film sensitivity SV data to 08. Set to bo-b5. A new film sensitivity Sv is obtained by adding the correction amount ΔSV (described later) stored in bo""b4 of 09o to this film sensitivity Sv (#925 to 935). Then, set the film sensitivity Sv to 44H, -b7 (for output to card) (#937) and return to FIG. 8.

Returning to FIG. 8, routines for card communication (2) and FL data communication (I) are performed (#210, 215).

FIG. 17 is a flow chart showing the routine of card communication H. First, data 408 indicating the communication mode (■) is stored. b, and set terminal C5CD to L level to 1.
It performs serial communication twice and outputs 40H data. Next, serial communication is performed three times, and the terminal C8CD is set to H level and the process returns (#720 to 735). In the above three serial communications, RAM address 43H
~ Information stored in 45H, i.e., photometric data B
vc1 film sensitivity Sv1 card function 0N10FF (
(described later), the presence/absence of release slide (0N10FF of β2), the amount of exposure shift and number of shots of the auto bracket card (described later), and the function data of 0N10FF of switch S1 are output from the camera to the card. The explanation of FL data communication (2) will be omitted since it has already been done (FIG. 7).

Returning to FIG. 8, after the above FL data communication I is completed, a flash mode routine is executed next. This determines the combination of use of the built-in flash and the external flash depending on the 0N10 FF state of the built-in flash switch and whether or not the external flash is attached.

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

First, it is determined whether the light emitting switch 5INF of the built-in flash is turned on, and if the switch 5INF is turned on, the terminal B5CN is set to H level to start boosting.
Enter data indicating whether an external flash is attached (
35,) (#735.740).

When an external flash is attached, it is determined whether the light emitting switch of this flash is in the ON mode based on the data in b4 of the OE (#745). When the switch is in the ON mode (04)1 b4=1), the flash mode FLM is set to "0" (both ON) and returns (#750). When the external flash is not installed or the external flash switch is in OFF mode (OEM b4 = 0), return with the flash mode FLM set to "1" (built-in flash only) (#755) . Built-in flash switch
If it is FF, the terminal B5CN is set to L level to stop boosting, and it is determined based on the input data whether an external flash is attached (#760.765). When an external flash is attached, determine whether the flash switch is in the ON mode or not, and if it is ON, return with the flash mode FLM set to "2" (external FL only) (#770 .775). When no external flash is attached or its switch mode is OFF, set the flash mode FLM to "3".
” (no flash) returns (#
780).

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

First, data indicating card communication ■ is set in bObl of 408, terminal C3CD is set to L level, and information of 40H is output from the camera to the card (#1030 to 1035
).

Next, input 3 bytes of data from the card to RAM addresses 49H to 51H, set terminal C8CD to H level, and return (#1040.1 Returning to Figure 8, exposure calculation (AE calculation) and flash Interlocking range calculation (
FL operation) ($225.230).

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

First, in the AE calculation, focal length data f(
21H), the camera shake limit speed TVf is obtained (#800). Its value is the reciprocal of the focal length. Then, the exposure value EV is EV = S V + B V c + A V
.

The control exposure value is determined by adding the exposure correction amount ΔEV (#810.815). However, A V o is the RAM address 20. This is the maximum aperture value of the lens stored in the memory, and the exposure compensation amount ΔEV is 03 as will be described later.
It is stored in b3 to b7 of M. Next, the AE mode is determined from the data of bObl of 038. In the program (P) mode, the photometry mode is auto mode (see Figure 11), so it is determined whether the brightness difference ΔBV between the spot photometry value and the average photometry value exceeds 2, and the brightness difference is 2. If it is below, camera shake limit speed TVf and open aperture value A
The sum EVf with Vo is determined and compared with the obtained control exposure value EV. If EV≧EVf, assuming that camera shake will not occur, the shutter speed TV and aperture value AV are determined from a predetermined program diagram based on the control exposure value EV, and a flag FLF indicating flash emission is reset;
Proceed to step #865 (#825-845). If the brightness difference exceeds 2 in step #825, it is considered a backlight condition, or if EV<EV
If f, it is assumed that there is a high possibility that camera shake will occur, and the process proceeds to step #850. Then, the flag FLF indicating that flash emission is necessary is set, the shutter speed TV is set to the synchronized TVx (1/125), the aperture value AV is determined as AV=EV-TV, and the process proceeds to step #865 (# 850-86
0).

If the AE mode is the shutter priority (S) mode, the aperture value AV is determined by EV-TV, and it is determined whether the flash mode FLM is "3" . . . flash non-emission. If the mode is not “3”, proceed to step #850;
Performs control for flash emission and mode is "3"
If so, it is determined that the flash is not emitted and the process proceeds to step #865 (#890.895).

If the AE mode is aperture priority (A) mode, calculate the shutter speed TV by EV - AV and set the flash mode FL.
It is determined whether M is "3". If the mode is "3", immediately step #86 as the flash is not emitted.
Proceed to step 5 (#900.905). On the other hand, mode or “3”
If not, set the shutter speed TV to the synchronized speed TVx,
Set the flash light emission flag FLF and proceed to step #
Proceed to 865 (#910.915).

If it is the manual mode, that is, the M mode, it is determined whether the flash mode FLM is "3". If the mode is "3", immediately proceed to step #865; if the mode is not "3", proceed to step #915 (
#920).

In step #865, it is determined by OCH b5 whether there is a card, and if there is a card, it is determined whether the function is ON or not by OCH b6 (#865.870)
. If the function is ON, the shutter speed (TVco...49H) and aperture value (AVoD-
...50H), the shutter speed for control (TV
...0114) and returns as the aperture value (AV...02H) (#875.880). If there is no card or the function is OFF, return immediately.

Next, in FIG. 21, first, a flash is generated based on the data input from the card. ff signal (bo of 51H)
If it is not off, determine whether the flash mode FLM is "3" (non-emission) (#
950.952). If the flash mode is not "3", it is determined whether the flash mode is "1" (only the built-in flash is ON) (#955). If the flash mode is "1", the minimum light output of the built-in flash (I

). In addition, DVmin and DVmax are 049 b1~
b6.05H. -b6 respectively. If the flash mode is not "1" in step #955, the process advances to step #960. At this time, at least the external flash is attached and turned on, and 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 is allowed to emit light, the built-in flash is prohibited from emitting light.

Therefore, in step #960, the shortest interlocking distance DVmin of the flash is determined from the minimum light emission amount IVmin' input from the external flash as DVmin=IVm
Calculate by i n' +5V-AV. And H/L (

Set the mode to OEH (can emit light up to 4 steps below the maximum light output) Judging by the signal, if it is L mode,
Maximum light emission amount ■Vmax' minus 4 is set as the maximum light emission amount, and the process proceeds to step #975 (#970). If it is determined in step #965 that the mode is H mode, the process also advances to step #975. In step #975, the longest interlocking distance DVmax is calculated from the maximum light emission amount IVmax' by DVmax=IVmax'+5V-AV, and it is determined from the flag FLF whether or not flash light emission is necessary (#975.990).

If a flash is required here (FLF=1),

If it is the low-speed continuous shooting mode (3 frames per second), the process waits for 300 m5eC and then proceeds to step #185; if it is not the low-speed continuous shooting mode, it is the high-speed continuous shooting mode, so the process immediately proceeds to step #185. If the release switch S2 is OFF in step #245 or there is release prohibition data from the card, or in step #250
If the camera is not in focus (AFEF=O), it returns immediately.

FIG. 22 is a flowchart showing a subroutine for exposure control.

First, the microcomputer μC performs FL data communication (2) with the flash (#1050). Then, the camera side sets the flash control mode (FL control data set) based on the set flash control data (OEH bo""b4), exposure control... aperture and shutter control...

Returning to FIG. 3, in step #10, if the photography preparation switch S1 is OFF, the flag APZF indicating the APZ mode is reset, and the call mode...a mode for setting various data, photography mode, etc. Determine whether switch 5call, which calls
#25.30). If the switch Scal is turned ON, execute the call ON flow indicating that it has been turned ON (#35), and send the display data to the display control circuit DISPC.
A predetermined call mode is displayed on the display section DISP, and the process proceeds to step #20 (#50). If the switch Sea l l is OFF, it is determined whether a flag (call F) indicating the call mode is set. If the call flag is set, execute the flow as set mode, output display data, and proceed to step #20 (#40.45.5
0).

FIG. 27 is a flowchart showing the call ON subroutine. First, a flag (call F) indicating that switch 5call is turned on is set, and card communication ■ is performed (# 1205°1210). Based on the data input from the card through card communication I, the card is inserted. If it is installed (OCH b5 = 1), determine whether the card function is ON, and if it is ON (OCR b8 = 1), is the auto bracket card installed? Determine whether or not (#1
215-1222). If the auto bracket card is not installed (OB, b5 = O), set address 08, b5 and b6 to indicate call mode ■, and change the display to call mode ■ (address OOH). -b7=14H), and the flag Sc is set when setting data in call mode (details will be described later).

By the way, when data is output to the display, the display control circuit DI
Based on the input data, SPC selects DP-1 to DP-1.
The display shown in FIG. 6 is displayed on the display unit DISP, but since the above explanation has made it clear how the display is performed, here we will focus on explaining the parts that are difficult to understand in the display diagram.

In the display of DP-1 and DP-1', the flash dimming range is displayed when shooting fra-sauche, and the focal length is displayed when the lens is attached. b 7 , b of ODH
It is determined based on the data of 5.

In the DP-2 display, the rcARDJ display is displayed only when a card is installed, and in the DP-3 display, rFLAsHJ is displayed only when an external flash is installed, and each OCM b5 , OEH b
It is judged as 5.

Also, rBRAKTJ or rsPO in DP-1
RTJ negative display indicates that the card is installed and the function is ON.
It is displayed when the switch is configured. That is,
If you turn it ON while rBRAKTJ is displayed,
Directly, the data setting process necessary for auto-bracketing as shown in Figure 36 is performed, and if you turn it ON when rsPORTJ is displayed, the call mode ■ will be displayed (Figure 28 DP-

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

If the call flag (call F) is not set in step #40, the process advances to step #55.

When the flag (timer F) for resetting and starting the timer timing is set, this flag is reset, the timer is reset and started, and the process proceeds to step #70 (#55 to #65). Even if the flag (timer F) is not set in step #55, the process proceeds to step #70, and in #70, it is determined whether or not 5 minutes have elapsed on the above-mentioned timer, and if it has, halt control is performed. It becomes a halt (#70.75). If 5 minutes have not passed,
Execute the data setting subroutine (#76), execute the switch S1 ON subroutine, and step #10.
Return to 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, aperture value, and 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 and D shown in Fig. 2B.
It is displayed as P-1' and rsP.

The negative display section labeled RTJ or rBRAKTJ is a switch, and is displayed when a card is present and its function mode is turned on. First, in this flow, the switch S. It is determined whether or not 6 is turned on.

When the switch is not turned on, a flag S indicates that the switch is turned on. Determine whether NF is set, and if not set, step #390
Proceed to. Flag S. When NF is set, switch S. 6 has changed from ON to OFF, the process advances to step #387 to perform various settings. Next, it is determined whether or not the bracket mode is in effect, and if it is in the bracket mode, it executes subroutine AEB, and if it is not in the bracket mode, it executes the call mode ■ and returns (838).

If N (QC, bs of), step #382
Then, it is determined whether the installed card is a bracket card (BS of OB)l). If it is a bracket card, set data (10H) as bracket mode in b0 to b7 of 00H, and if no bracket card is installed, set data (14H) as call mode.
). Next, switch S. Set flag 5cNF indicating that 6 is turned on and return (#
379-385). On the other hand, if the card is not installed,
Alternatively, if the card function is OFF, the process returns directly.

If you have proceeded to step #390, step #390
Now, determine whether the current AE mode or P mode is selected (#
390). The determination of this AE mode (the same applies to modes other than the P mode described below) is made at 03H. , b. If it is P mode, return as is. P

If the mode is not I in step 391, it is determined whether the mode is S mode (#392). In S mode, if the up switch SUP is ON, the shutter speed is TV = TV + 0.5, and if the down switch SDN is ON, TV = TV-.
0.5 and return (#400 to 415). If no switch is operated, the process returns immediately.

If it is not S mode in step #392, that is, M mode or A mode, the up switch S U
In response to the operation of the P% down switch SDN, the aperture values are returned as AV=AV+0.5 and AV=AV-0,5, respectively, and if there is no operation, the process returns immediately (#420 to 435).

In step #391, if the mode is I, it is determined whether the mode is M mode. If it is M mode, step #40
The process advances to 0 to change the shutter speed, and if the mode is not M mode, the process advances to step #392 (#395).

Next, the light control circuit and the built-in flash circuit are shown in FIG. 43 and will be explained.

First, a circuit related to data communication will be explained.

When a momentary H level signal is received from terminal C3FL,
This signal is output from the OR circuit OR2 to the flash. Next, a data communication clock is output from the terminal SCK and connected to the flash via the OR circuit OR2. When data is output from the camera side in synchronization with this clock, it is output from the terminal 5OUT to the flash via the OR circuit ORI and the input/output switching circuit (10 switching).

At this time, the input/output switching circuit is switched to the output side. When inputting data, the data is input from the terminal ST2 to the terminal SIN via the input/output switching circuit.

Next, the dimming circuit will be explained. The light receiving element 5PCI connected to the dimming circuit LAC dims the area around the shooting screen,
The light receiving element 5PC2 dims the center of the photographic screen. When the switch SP connected to the light receiving element 5PCI is ON, light control is performed in both ranges (wide light control), and when the switch is OFF, spot light control is performed based only on the center of the photographic screen. This light control circuit LAC is capable of changing the amount of light control in accordance with the film sensitivity based on a signal obtained by converting film sensitivity data into an analog signal. Eight H-level signals are output from the terminal STP in the auto mode, depending on whether the light is to be dimmed (auto mode or not).

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 is transmitted to the flash via the AND circuit ANI, OR circuit ORI, and input/output switching circuit. . The built-in flash is connected from the AND circuit AN1 to the light emission control circuit ECCl.
is sent to terminal STP.

Built-in flash is booster circuit BS1, rectifier diode R
It consists of DI, a light emission capacitor MCI, and a light emission control circuit ECCl for stopping the flash light emission.

When the front curtain run is completed, the X contact is ONL, and this signal is
The signal is inverted by the inverter INI and output to the AND circuit AN3, and the signal delayed by the delay circuit DLI is output to the AND circuit AN2. AND circuits AN2 and AN3 are supplied with a signal from terminal STT indicating whether rear curtain synchronized light emission is being performed (an H level signal if trailing curtain synchronized light emission is being performed).
is input and if rear curtain synchronized light emission, AND circuit A
From N2, if the first curtain synchronized light is emitted, the AND circuit AN
3 outputs a light emission signal to an AND circuit AN4. A signal indicating whether light emission is enabled/disabled is input/output from the terminal LE to the AND circuit AN4, and when the light emission is disabled, an L level signal is inputted thereto. When it is possible, 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 receives a signal from the terminal INFL indicating that only the built-in flash is enabled to emit light, and outputs a light emitting signal if the flash is not disabled, that is, if an H level signal is output from the terminal INFL.

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

In the figure, the flash circuit includes a battery E F L 1 diode D3 and a backup capacitor BUC.

Microcomputer μC2 that controls flash, booster circuit B
S2, light emitting capacitor MC2, rectifier diode D2,
and a light emission control circuit ECC2.

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

The operation will be explained below with reference to FIG.

When any signal is input from terminal STI, the interrupt shown in FIG. 45 is executed. First, interrupts to this flow are prohibited, data is exchanged with the camera, and 1 byte of data (RAM address 30 1 data) is input (
#FL-5, 10). At this time, a transfer clock is manually input from the terminal STI, and data is input from the terminal ST2 in synchronization with this. At this time, since a signal at the rLJ level is input from the terminal 5TEN of the microcomputer μC2 to one input of the AND circuit AN6, the signal does not reach the light emission control circuit ECC2. Based on the data input to the terminal ST2, the microcomputer μC2 determines whether exposure control is being performed, and if it is not exposure control, outputs 3 bytes of data (contents of RAM addresses 35. to 37H) (#FL- 15,20
). Note that the data contents have already been explained, so the explanation will be omitted here. Furthermore, based on the input data, it is determined whether the flash is 0N10FF or not.
If N, set the terminal BCN to H level to start boosting, and if OFF, set terminal BCH to L level to stop boosting, and return as interrupt enabled (#FL-2
5-40).

In step #FL-15, when it is determined that exposure control is to be performed, the terminal 5TEN is set to H level, and the light emission stop signal from the camera side is sent to the OR circuit OR3 and the AND circuit AN6.
, and wait for the X contact to turn on.
When turned ON, start the timer (#FL-45 to 55)
. Based on the input data, it is determined whether rH/LJ... rHJ can emit the maximum amount of light, rLJ can emit 1/16 of the maximum amount of light, etc., and if it is not rLJ, step #FL is performed.
Proceed to -75. If it is rLJ, wait until T = TA (the time when the amount of light emission becomes 1/16), and when T = TA, output a "just" signal to stop the light emission from terminal STP. , proceed to step #FL-75. Step #F
L-75 waits for a certain period of time, sets terminal 5TEN to L level, and then enters a halt state as interrupts are enabled (#FL-
75.80, #FL-40).

FIG. 46 is a circuit block diagram of the lens, and FIGS. 47 and 48 are flowcharts of the in-lens microcomputer μC3 that controls the operation of the lens.

The operation will be explained below with reference to the drawings.

When a signal of L level is input from the camera to terminal C3LE, the interrupt operation shown in FIG. 47 is executed.

First, the terminal S is synchronized with the clock input to the terminal SCK.
Input 1 byte of data at address OAH in RAM from IN (#L-5). Next, based on the input data, it is determined whether the mode is data output mode. In output mode, terminal S is output based on the clock input from the camera. Five bytes of data are output from Ua, and then zoom control (Z control) is performed (SEL-10, 20).

This zoom control will be explained with reference to FIG. 48. Based on the data input from the camera (RAM address 2CH), it is determined whether or not the APZ mode is selected, and if it is the APZ mode, the focal length data input from the camera ( The focal length f is controlled based on the RAM address 28H) and the process returns.

If not in APZ mode, tele side zoom switch SZT
Alternatively, depending on the operation of the wide side zoom switch Szw, the telephoto side zoom and the wide side zoom are controlled respectively, and the process returns (#L-40 to #L-65).

The zoom control described above includes the zoom driving direction and start,
Zoom drive circuit Z sends a stop signal. Based on the input signal, the zoom drive circuit
Drives the motor for driving the zoom lens. Control to a predetermined focal length is performed by inputting a signal from the zoom encoder Z·EN indicating the current focal length.

In step #L-10 of FIG. 47, if it is not the output mode (No in SL-10), 2 bytes of data (RAM addresses 2BH, 2CH) are input from the terminal SIN (#L-25). Based on this input data, it is determined whether the camera's power is ON10FF, and if it is ON, the process proceeds to step #L-20, and if it is OFF, the camera is powered on.
The zoom is stopped as it is an FF, and the microcomputer μC3 stops its operation (#L-35).

In FIG. 46, the encoder DVEN outputs a signal indicating the subject distance D7 where the lens is in focus. This data is output to the camera side. Also,
Zoom control circuit Z. N is a specific power line (Vc c
5GND2).

Other than that, it has conventional power supply lines (Voo, GNDl).

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

First, when an L level signal is input from the camera terminal C8CD, the interrupt control shown in FIG. 49A is executed. Terminal S is synchronized with the clock input from camera terminal SCK.
Input 1 byte of data (RAM address 40M) to IN (#CD5). Based on this input data, in mode I (corresponding to communication I on the camera side), 1 byte of data indicating the card type (RAM address 41
H) Output and return (#CD40.15). If it is not mode 5, it is determined whether it is mode 2 (corresponding to communication 3 on the camera side). In mode ■, input 3 bytes (RAM addresses 43H to 45H) of signals such as photometry data, film sensitivity data, camera switch status, and auto bracketing data from the camera, and turn off the card function from the input data. Determine whether or not.

If the card function is OFF, the process returns; if it is ON, a subroutine exposure calculation is performed and a halt state is entered (#CD-20 to 35). If it is not mode ■, set it to mode ■ (corresponding to communication ■ on the camera side), and store the shutter speed TVo81 aperture value AVoD and camera control data in total of 3 bytes (RAM addresses 49H to 51H).
Output and return (#CD-40). Note that 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=BVc +SV based on the information input from the camera, and from this exposure value, the shutter speed TvoD, aperture value AVc,
is determined and set as output data to the camera (#CD-45, 50).

Then, after setting to display the presence/absence of flash emission, prohibition of release, presence/absence of continuous shooting, etc. in the table of FIG. 50, the process returns (#CD-55). Since this exposure program is compatible with sports scenes, it is a program that prioritizes high shutter speeds.

FIG. 49C shows the exposure calculation subroutine of the auto bracket card.

First, it is determined whether the photographing preparation switch S1 is ON based on information input from the camera, and if it is ON, it is determined whether release prohibition data is set in the card. If it is set, it returns as photography is prohibited (#CD-57, 58). If switch S1 is not ON, reset the release prohibition data and proceed to step #CD.
Proceed to -60 (#CD-59). Step #CD-58
Even when release prohibition data is not set in
Proceed to step #CD-60. In step #CD-60, it is determined whether the release switch S2 is turned on or not. If it is not turned on, the exposure value EV is calculated as EV=BVo+SV and the variable N is set to O. Furthermore, set the control data as shown in the table in Figure 50, and set the exposure E determined above.
Determine shutter speed TVco1 aperture value AVCD from V and return as output data (#CD-6
5-80). Here, in this exposure program, the change in shutter speed and aperture value is 1 for each change in exposure value.
The ratio is 1 to 1. 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, set the variable to N=N+1, calculate the shift amount ΔEV from the exposure shift amount input from the camera, and then determine the variable N (#CD-85
, 88, 90). If N=1, the exposure value EV is calculated as EV=EV-ΔEV in order to overexpose by ΔEV, and it is determined whether the number of shots set for shooting N82T is 1, and if it is 1, the release is prohibited. Set the data and proceed to step #CD-75 (#CD-95 to 105
). This is because when the flow reaches step #CD-100, the first photograph has always been taken. In other words, when the number of film shots is 1, shooting of the second film is prohibited. Number of shooting set images N5ET is 1
Otherwise, do nothing and proceed to step #CD-75.

If N = 2, the exposure value E is set so that the exposure amplifier is only ΔEV.
Set V as EV=EV+2ΔEV and proceed to step #CD-75 (#CD-110,
115), if N=3 and J5tL, set the exposure value EV to be EV=EV-3ΔEV to overexpose by 2ΔEv, and determine whether or not the number N5ET of photographic sets is 3. If it is 3, set release prohibition data, and if not, immediately proceed to step #CD-75 (#C
D-120 to 130). If it is N22, set the exposure value EV to EV=EV+Δ4EV to set the exposure amplifier by 2ΔEV, and if it is not N22, set release prohibition data and proceed to step #CD-75 (#CD-150).
. Therefore, when shooting with exposure shifts using an auto bracketing card, the following methods are used: proper exposure, ΔEV over, ΔEV under, 2
This is done in the order of ΔEV over and 2ΔEV under.

E. Effects of the Invention As described above, this invention improves usability by displaying only the photographing information according to the program mode set by inserting the IC card and allowing the user to set this.
