Then, the input/output switching circuit (see FIG. 43) is switched to the input side. Next, serial communication SI○ 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 358 to 37. This is the content that is stored in the memory.

Returning to FIG. 3, when the subroutine for turning on the main switch SM (#5) is finished, it is determined whether or not the photographing preparation switch S1 is turned on (#10). If it is turned on, the process proceeds to step #15. , S, and resets the flag 5cNF indicating that any of the switches SC7 to SC9 has been turned ON. 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 (180).

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

It is also stored in ~b7.

In the card communication (2) shown in FIG. 10, data 408 indicating the communication I mode is stored. Sb, set terminal C5CD to L level to indicate card data communication mode, perform serial communication once and output data (40H) indicating card communication I, then input 1 byte of data from the card. (#330-340). This data indicates the presence/absence of a card and the type of card, and is stored at address 41H of the RAM. Then, to indicate the end of the data communication mode, the terminal C8CD is set to H level, and it is determined from the input data whether a card is present or not. If there is no card, please reset the data with card. b5- of OCH

).

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 FIG. 11 and FIG. 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~
Input the A/D converted digital data BV1 to BV9 of 9 and judge the set photometry mode (#4
50.455). This determination is made based on data b5 to b7 of RAM address 07M. When in auto mode, the control photometric value BVo is the average of all photometric values, and BVc = (BVl+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 BVo is determined as follows from the photometry values obtained from the photometry areas on the right side of the screen and in 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 BVc = (BVI+・+BV9)/9 If the photometry mode is the third mode, the lower side The control photometry value Bvc is obtained from the photometry values obtained from the photometry area in the center of the screen and the photometry area in the center of the screen as follows.In other words, BVo= (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 the fifth mode, the control photometry value BVc is determined as follows from the photometry values obtained from the photometry areas on the left side of the screen and the center of the screen.

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

Note that the data BVC is stored at address 43.4 of the 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 'b of RAM address 09H.
e, b7 (for this, the 39th
This is determined based on data (described later using figures).

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

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 (FL), 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

Set it as the current AF-1-on (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 one-shot AF (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,
Defusal waste amount DFI to DF for each focal-lateral ratio area 1 to 5

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 the non-inspection ratio area 2.3.4 represents the closest subject, positive is front focus, negative is rear focus The control defocus amount DF is
(#540). Zone or 3rd zone (wide)
If so, the maximum defocus amount in the all-focus pressure detection area is set as the control defocus amount DF (#545). After calculating the control defocus amount DF, step #550
Proceed to (#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 or not the focus is locked using the focus lock flag FLKF #560

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. The lens driving amount N is obtained by multiplying the amount by the value (stored in memory), 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 OB and be b (#670). If that mode is OFF, return immediately. If the mode is P (program) 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). For this purpose, it is sufficient to have the object distance Dv as an address and the focal length f based on the photographing magnification as a memory such as a ROM table.

Next, for upper body mode (ρ), 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=B2・
Obtain the focal length f as Dv (#685). However, the subject distance DV is input from the lens (described later), and the RA
M's address 23. This is what is stored in memory. Note that the focal length f obtained by the above calculation is stored at address 2BH of the RAM for driving the zoom lens.

After obtaining the focal length f in the above steps, it is determined whether a flag APZF indicating this APZ mode is set (#690). If 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 indicating that the camera is in data output mode to the lens is inserted. and terminal C3LE
is the L level. Then, first perform SIO once and output the data of bo-b7 of 2 people H, then 2HM, 2
After performing SIO twice on the data of C and a, set the terminal C5LE to H level and return (#1690 to 1
710).

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, the lens drives the zoom lens based on the lens data output (2BM'), and then
Return to the flow shown in FIG. 8 (#715). Note that the zoom drive motor is provided on the lens side (fourth motor).
(See Figure 6).

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, the film sensitivity Sv is read from the film, and the film sensitivity Sv data is 08. Set b0 to b5. The correction amount ΔSv (described later) stored in 09)417)bo=b4 is added to this film sensitivity Sv to obtain a new film sensitivity Sv (#925 to 935). and,
This film sensitivity Sv is 44. Nosu. -b7 (for output to card) (#937) and return to FIG.

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 (2). First, data indicating the communication mode ■ is set in bobt of 40H, terminal C5CD is set to L level, one serial communication is performed, and data of 40o is output. Next, serial communication is performed three times, and the terminal C3CD
Set to H level and return (#720-735)

, the amount of exposure shift and the number of shots (described later) of the auto bracket card, and the function data of 0N10FF of switch S1 are output from the camera to the card. FL data communication I
Since the explanation has already been completed, the explanation will be omitted (Fig. 7).

Returning to FIG. 8, after the above FL data communication I is completed, a flash mode routine is executed next. This combines the use of a built-in flash with an external flash,
This is determined depending on the ON10FF state of the built-in flash switch and whether or not an 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 5xNF is turned on, the terminal B5CN is set to H level to start boosting the voltage.
Enter data indicating whether an external flash is attached (
35H) (1735.740). When an external flash is attached, it is determined whether the light emitting switch of this flash is in ON mode based on the data of b4 of OEH (#745). switch is on
When in the N mode (ba = 1 in 04H), the flash mode FLM is set to "0" (both ON) and returns (#750). When the external flash is not attached, or when the external flash switch is in OFF mode (OE H, +=, o), returns with the flash mode FLM set to "1" (built-in flash only). (#755). If the built-in flash switch is OFF, set terminal B5CN to L level to stop boosting, and determine whether an external flash is attached based on the input data (#760.765)
. When an external flash is attached, it is determined whether the light emitting switch is in ON mode or not, and if it is ON, the flash mode FLM is set to "2" (external FL
only) (#770.775). When an external flash is not attached or its switch mode is OFF, return the flash mode FLM as "3" (no flash firing).
#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 408 indicating card communication ■ is inserted. bl, set terminal C3CD to L level, and input 408 information 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 C3CD to H level, and return (#1040.1 Returning to Figure 8,
Exposure calculation (AE calculation) and flash interlocking range calculation (FL calculation) are performed (#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 E■ is EV=SV+BVo+AV.

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 H. Next, the AE mode is determined from the bob+ data of 03H. If the program (P) mode is selected, 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. 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, the flag FLF indicating flash emission is reset, and the process returns to step #865. Proceed (8825-845). If the brightness difference exceeds 2 in step #825, it is considered a backlight condition, or in step #835, EV<EVf
If so, it is determined that there is a high possibility that camera shake will occur, and the process proceeds to step #850. Then, set the flag FLF indicating that flash emission is required, set the shutter speed TV to synchronous TVx (1/125),
Find the aperture value AV as AV=EV-TV and proceed to step #865 (#850 to 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”
Otherwise, set the shutter speed TV to the synchronized speed TVx,
Set the flash light emission flag FLF and proceed to step #
Proceed to 865 (3910, 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 OCR b5 whether or not there is a card, and if there is a card, it is determined whether the function is ON or not by OCH be (#865.870
). If the function is ON, the shutter speed (TVco...49M) and aperture value (AVCD
...50H) and the shutter speed for control (T
V...01H) and aperture value (AV...02H) (#875.880). If there is no card or the function is OFF, return immediately.

Next, in FIG. 21, the flash off signal (51H) is first activated based on the data input from the card.
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 (
IVmin) (memory in the camera) to the shortest flash linkage distance DVmin = DVmin=
Calculated by I Vmin + 5V-AV, and the longest flash shooting distance (DVm
ax) as DVmax=IVmax+5V-AV and proceed to step #990 (#980.985
), DVmin and DVmax are from b1 of 04H.
b6.05H and -be are respectively memorized. If the flash mode is not "1" in step #955, the process advances to step #960. At this time, at least an external flash is attached and turned on, and in this embodiment, if the external flash is capable of emitting 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 I Vmin' input from the external flash as DVmin=IVmi
Calculate by n' +5V-AV. And H/L (H...
・Flash can fire up to maximum flash output, L...Flash can fire up to 4 steps below maximum flash output
E, Nosu. If the mode is L mode, the maximum light emission amount is determined by subtracting 4 from the maximum light emission amount Vmax', and the process proceeds to step #975 (#970). Step #
If it is determined in step 965 that the mode is H mode, the process also proceeds to step #975. In step #975, the maximum light emission amount I
The longest interlocking distance DVmax from Vmax' is determined by DVmax=IVmax' +5V-AV, and it is determined from the flag FLF whether or not flash emission is necessary (#975.990).

If flash emission is required here (F L F =
1), b7 of data 048 for turning off the interlocking range display
．． Set b7 of 05H to “0” and return (#
1005.1010). If the data from the card is in flash off mode in step #950, or if the flash mode FLM is "3" in step #952.
If so, or if it is determined in step #990 that flash emission is not necessary (FLF=O), proceed to step #1015 and press b7 of 04o and b7 of 05H to turn off (do not perform) the display of the interlocking range. Set each and return (#1015.1020).

When the FL calculation is completed, the process returns to FIG. 8 and outputs data to be displayed on the display section DISP to the display control circuit DISPC (#240) (see FIG. 6). Then, it is determined whether the release switch S2 is turned on (#2
45). When the switch is ON, it is determined whether or not there is release prohibition data among the data input from the card (determined by the signal of 51H) (#2
47).

Flag AF indicating focus when there is no release prohibition data
Determine whether EF is set (#250
). If set, it is determined whether or not the self mode is set based on the data of 07.0Db and b2. If the mode is self mode, wait approximately 10 seconds, and if not the mode, skip step #260 and proceed to step #265 (#255, 260). And exposure control AE.

After performing a winding routine for winding one frame, it is determined whether or not the continuous shooting mode is set using 07H bl and b2.

If the mode is not continuous shooting mode, wait for the shooting preparation switch S1 to turn OFF, and return when it turns OFF (1265).
~280). In step #275, if the continuous shooting mode is selected, it is determined whether the mode is the low-speed shooting mode (1285). If the mode is 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, the process immediately proceeds to step 3185 since it is the high-speed continuous shooting mode. If the release switch S2 is OFF in step #245, or there is release prohibition data from the card, or if the focus is not in focus (AFEF=O) in step #250, the process immediately returns.

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

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

FIG. 23 is a flowchart showing the subroutine of FL data communication (2).

First, data indicating that the mode is exposure control mode is 30.
Set it to Nosu, set C3FL to H for a moment, and set address 3.
Output 0H data to flash and return (#
1065-1075).

FIG. 24 is a flowchart showing the FL control data set subroutine.

The data indicating these modes is the address OEM's bo-
b4, and the flash control mode is set based on this data. First, check whether it is second curtain synchronization or not.
It is determined based on the H bl signal, and if it is rear curtain synchronization, the terminal STP is set to H level, and if it is not rear curtain synchronization, terminal ST is set to H level.
P is set to L level and the process proceeds to step #1095. In step #1095, it is determined whether it is manual (full flash) or auto (dimming) using OEM's b2, and if it is automatic,
If terminal STP is H1 manual, terminal STP is set to L.
and proceed to step $1110 (#1095-11

FIG. 25 is a flowchart showing the winding control in step #270 of FIG.

First, wind one frame, and when the winding is complete,
It is determined whether or not the count-up mode is on based on the data in bl of OCH. If the count-up mode is set, the count N indicating the number of films is set to N+1, while if the count-down mode is set, the count N is set to N-1 and the process returns (#1160 to 1175). The number of films is determined by the RAM address 06. Nosu. -b6 is also stored.

Figure 26 shows the interrupt (
2 is a flowchart showing the RCINT) routine.

First, wind the film 3 frames, read the number of films from the film back cover with the DX code, and use this as NFC. Next, it is determined whether or not the count-up mode is on.
If it is in count-up mode (OCR b7 = 1),
If N=1 and film countdown mode (OCH b7=0), return as N=N and o (#1180 to 1200).

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 I is turned on, execute the flow of call ON indicating that it is turned on ($35), and send the display data to the display control circuit D I S
The call mode is output to the PC and 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
．． 50).

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 I is performed (#1205°1210). Through this card communication ■, the card is inserted based on the data input from the card. If it is installed (OCM b5 = 1), determine whether the card function is ON, and if it is ON (OCM ba = 1) is the auto bracket card installed? Determine whether or not (#1
215-1222). If the auto bracket card is not installed (OBH bs = O), set b5 and b6 of address 08H to indicate call mode ■, and change the display to call mode ■ (address 00H -b7). = 14n), and the flag Sc is set when setting data in call mode (details will be described later).

When switch Sc9 is OFF, the above flag 5c9ONF
Determine whether or not is set.

If set, switch S. 9 from ON to OFF
Therefore, assuming that the call mode has been changed, it is determined whether the current call mode is WORK or not based on the data of b5b6 of 08H. If the call mode is ■, the call mode is set to ■, and if the call mode is ■, the call mode is set to b5b6.00H of 08° each. - Change b7 and set flag S. 9Reset ONF and return (
#1250-1270).

If the call mode is set to ■ in step #1235, or flag 5c9ONF is not set in step #1250 (meaning that switch S.9 has never been operated), the process advances to step #1275, and the call mode is set to Determine what it is using b5b6 of 088.

6 is ON, data (09s) is set as the photo mode and the process proceeds to step #1625 (#1520 to #1545).

When the switch See is OFF, it is determined whether an external flash is attached. If the flash is installed, it is determined whether the switch S07 is ON or not, and if the switch Sc7 is ON, the data (11M) is set to the mode signal (b0 to by of 00H) as the flash mode. Then, the process proceeds to step #1625 (#1550-1560). If no external flash is attached or if switch S07 is OFF, proceed to step $1565 and switch S. 9 is turned on. If it is turned on, halt control is performed to turn off the main switch and the process returns (#1565.1570).

Switch S. If 9 is OFF, flag S.

It is determined whether NF is set or not, and if it is not set, it is assumed that no operation has been performed and returns immediately (#1575). When flag 5CNF is set, the mode is determined and changes are controlled according to the mode (details will be described later) (#1575 to 16

In step #1625, a flag is set indicating that any of the switches SC7 to sc9 valid in call mode (2) has been turned on, and the process returns.

Next, details of each of the above modes will be explained.

The display when setting the exposure compensation mode is shown at DP-5 in FIG. 2B. The display "r+/--2,0" is a numerical display of the current exposure compensation amount, and the display below it has the compensation amount "0" in the center, and 0. The number line is graduated in units of 5 EV, and the "convex" index indicates the amount of correction at that time.

The "tsu" and "◇" boxes at both ends (negative display) are
These are switches for performing correction on the negative side and positive side, respectively.

FIG. 30 is a flowchart showing correction control in this exposure correction mode. First, it is determined whether the switch Sc3 is turned on. If it is ON, the correction amount is set to ΔEV=ΔEV-0,5, and switch S is turned on. 3 is OFF and switch S. When switch 9 is ON, the correction amount is returned as ΔEV=ΔEV+0.5, and when both switches are OFF, the process returns without doing anything (#1700 to 1715). This correction amount is 63. is set to b3 to b7.

Next, the display when setting the AE mode will be described with reference to DP-6 in FIG. 2B.

The negative display portions rP, A, and 55M1 are switches, and the portion indicated by the index indicates the AE mode set at that time.

If it is N, it is S mode, switch S.

If 9 is ON, data for setting M mode is 03H.
Set bo and b+ and return. If neither switch is turned on, return without doing anything ($1720-1755).

Next, change the film sensitivity setting display to DP-7 in Figure 2B.
This is shown and explained below.

The value rIsO200J is the film sensitivity of the loaded DX film, and below it is a number line showing the sensitivity correction amount ΔSV.
The scale is marked so that correction can be made in 1/3 EV increments. The center scale is the correction amount "0", and the index indicates the correction amount at that time.

The left side is the overexposed side (lower film sensitivity), and the right side is the underexposed side (higher film sensitivity). The left and right negative displays are switches for setting the over side and under side, respectively.

FIG. 32 is a flowchart showing control of this setting.

Switch S. 3 is ON, the film sensitivity correction amount ΔSV is set to Δ5V-4SV-1/3 switch S. If 9 is ON, it returns as Δ5V=4SV+1/3, and if neither is ON, it returns immediately (#1760 to 1775).

This correction amount data is 09. is set to bo-b4.

The display of drive mode settings is shown in DP8 in Figure 2B. "S" is single shooting mode, "Evening" is low speed continuous shooting mode (3 frames per second), and "σ" is high speed continuous shooting mode (5 frames per second). ), "O" indicates self mode. Each one is a setting switch. The indicator indicates the current mode.

Next, when an external flash is attached, display the modes that can be changed using the flash function in Figure 2C.
It is shown and explained in P-16 (DP-16').

rHIGH/LOWJ is a switch that changes the maximum amount of light emission, and the current mode is "rHIGHJ or rLOW" that is currently visible. Regarding ``)/ri〈'', ``)'' is a switch that switches between front-curtain synchronized light emission and ``ri〈'' is a switch that switches between rear-curtain synchronous light emission, and the one that is currently visible indicates the mode. rMAN/AUTOJ is a switch for switching between full light emission (MAN...manual) and dimming (AUTO...automatic light control), and the one that is currently visible indicates the mode. "Dan" in the upper right is a switch that changes the dimming range between spot and wide, and the range indicated by that switch, that is, in the case of the display shown on DP-16, the center of the screen is DP-16' In the case of the display shown in , the entire screen is within the dimming range. For rONloFFJ, “O
"N" means to turn on the power of the strobe, and r○FFJ means to turn off the power to the strobe, and they are mutually switching switches. Indicates the currently visible switch or its mode.

Next, change the mode setting display for APz mode to D in Figure 2C.
It is shown and explained on page P-17.

Among the negative displays, the negative display of "husband" is displayed with a switch to switch to whole body mode (photographing magnification β2 = 1/100),
Ql'' is a switch for setting the upper body mode (imaging magnification β, = 1/60), and rPJ is a switch for setting the program mode. rOFFJ is a switch that turns off this mode. Indicates the mode the indicator is currently set to.

FIG. 41 is a flowchart showing this control.

First, switch S. If 2 is ON, whole body mode ("+" mode), switch S. 3 or ON, the program mode is set. If the switch SC5 is ON, the upper body mode ("ρ" mode) is set. If the switch S09 is ON, the mode is OFF, and the data set in b6 and b7 of OBH are set. Set (#2180-2215)

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 DrSP, but since it is clear from the above description 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 flash photography is being performed, and the focal length display is displayed when a lens is attached.
Each 04. b7.05H b7, ODH bs data is engraved.

On the DP-2 display, the rcARDJ display is displayed only when the card is installed, and on the DP-3 display, rFLAsHJ is displayed only when the external flash is installed, and each OCR bs , OEM b
It is determined by s.

Also, rBRAKTJ or 1'-3 in DP-1
The FORTI negative display is displayed when the card is installed and the function is ON, and has a switch configuration. That is, if you turn it ON while rBRAKTJ is displayed, the data setting process necessary for auto bracketing as shown in Figure 36 will be performed directly, and if you turn it ON while rsPORTJ is displayed, the call mode ■ will be displayed (see Figure 28). Diagram D
P4) 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 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 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 the timer has elapsed for 5 minutes, 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 switch S06 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, DPl and DP shown in Fig. 2B.

The negative display section labeled RTJ or rBRAKTJ is a switch, and is displayed when a card is present and the 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 the mode is bracket mode or not, and if the mode is the bracket mode, subroutine AEB is executed, and if the mode is not the bracket mode, the call mode ■ is executed and the process returns (#38).
6-389).

Step #379 Switch S. If 6 is ON, the process advances to step #380. At step #380, the card is installed (BS of OCH) and the card function is 0.
If N (BS of OCR), proceed to step #382, and determine whether or not the installed card is a bracket card (OB+(BS of). If it is a bracket card, set the bracket to bo-b7 of 00I. Set the data (10H) as the mode, and if the bracket card is not installed, set the data (14H) as the call mode.
Set. Next, a flag S indicating that the switch S06 has been turned on. Set NF and return (#3
79-385). On the other hand, if the card is not installed or 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 is P mode or not (#
390). The determination of this AE mode (the same applies to modes other than the P mode described below) is made at 03H. This is done based on Sbl. If it is P mode, return as is. P
If it is not the mode, the switch SMI is turned on (

In mode I, when in M mode, change the shutter speed by operating the up/down switches 5LJP and SDN, and if not in mode I, change the aperture value by operating the up/down switches SUI'%S[)N. change. If the mode is not ■ in step #391, it is determined whether the mode is S mode (#392). If in S mode, up switch S.

If 2 is ON, set the shutter speed to TV=TV
+0.5 If the down switch SDN is turned on, TV=TV-
0.5 and return (#400 to 415). If no switch is operated, the process returns immediately.

If step #392 is not in S mode, that is, in M mode or A mode, the up switch S U
Ps down switch S. In response to the operation of N, the aperture value is returned as AV=AV+0.5 and AV=AV-0,5, respectively, and if there is no operation, the aperture value is returned 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
Proceed to 0 to change the shutter speed, and if it is not M mode, proceed 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 high level signal is momentarily output 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 taro clock, it is output from the terminal 5OUT to the flash via the OR circuit ORI and the input/output switching circuit (I10 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. An H level signal is output from the terminal STP in the auto mode, based on whether or not to dim the light (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 BSI, rectifier diode R
D1, a light emission capacitor M C1, 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 DLL is output to the AND circuit AN2. A signal indicating whether or not rear-curtain synchronized light emission is to be performed is inputted to the AND circuits AN2 and AN3 from the terminals S and TT (an H level signal if the rear-curtain synchronized light is emitted). From AN2, if the front curtain synchronized light emission, AND circuit,
A light emission signal is outputted from A and N3 to an AND circuit AN4. A signal indicating whether or not to emit light is input/output from the terminal LE to the antenna circuit AN4, and when the light emission is not possible, an L level signal is input. When it is possible, an H level signal is input,
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 built-in flash is not allowed to emit light, 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 EFLs 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 ST1, 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 (data at RAM address 30°) is input (#
FL-5, 10). At this time, a transfer clock is 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 or not the exposure control is being performed. If it is not the exposure control, the data is stored in 3 bytes (RAM address 3
Contents of 5H to 37H) Output (#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, determine whether the flash is ON10 F F,
If ON, the terminal BCN is set to H level to start boosting, and if OFF, terminal B'CH is set to L level to stop boosting, and returns as interrupt enabled (#FL-
25-40).

In step #FL-15, when it is determined that exposure control is required, the terminal 5TEN is set to H level, and a light emission stop signal from the camera side is output from the OR circuit ○R3 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...[HJ allows maximum light emission, rLJ allows light emission of 1/16 of the maximum light amount..., and if it is not rLJ, step #FL
Proceed to -75. If it is rLJ, wait for T = TA (this is the time when the amount of light emission becomes 1/16), and when T = TA, output the "J''L" signal to stop light emission from terminal STP. Then, proceed to step #FL-75. In step #FL-75, after waiting for a certain period of time and setting the terminal 5TEN to the L level, interrupts are enabled and a halt state is entered (#F
L-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 C5LE, 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 the LIT, and then zoom control (Z control) is performed (#L-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 ( Based on the address 2BH of RA~1), the focal length f is controlled 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 tele 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 #L-10), 2 bytes of data (RAM address 28H, 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 D■ where the lens is in focus. This data is output to the camera side. Also,
The zoom control circuit ZCN is connected to a specific power supply line (Vc c
, GND2).

Other than that, conventional power supply lines (Vcc, GND
l).

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

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.
1 byte of data (RAM address 401 (
) (#CD-5). Based on this input data, if the mode is ■ (corresponds to communication on the camera side),
Return 1 byte of data indicating the card type (RAM address 41H) (#CD-10, 15)
). If it is not mode I, it is determined whether it is mode ■ (corresponding to communication ■ on the camera side). In mode ■, input 3 bytes (RAM addresses 43. to 45H) of signals such as photometry data, film sensitivity data, camera switch status, and auto bracketing data from the camera.
It is determined from the input data whether the card function is OFF 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 ■, then as mode ■ (corresponding to communication ■ on the camera side), the shutter speed TVcD1 aperture value AVc and camera control data are stored in a total of 3 bytes (RAM address 49) I 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=BVo+SV based on the information input from the camera, and from this exposure value, the shutter speed TVoD and aperture value AvoD are determined according to a predetermined program.
is determined and set as 8 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, the camera returns as photography is prohibited (#CD-57, 58). If switch S1 is not ON, reset the release prohibition data and press step #CD.
Proceed to -60 (#CD-59). Step #CD-58
Even when release prohibition data is not set,
Proceed to step #CD-60. Step: In the 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 zero. Furthermore, set the control data as shown in the table in Figure 50, and set the exposure E determined above.
Determine shutter speed TVcD1 aperture value AvoD from V and return as data for 8 lenses (#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, calculate the exposure value EV as EV=EV-△EV to overexpose by ΔEV, and set the number of shots! Determine whether or not the SE function is 1, and if it is 1, set the data to prohibit release and proceed to step #CD-75 (#CD-95 to 1
05). This means that the flow is this step #CD-100
This is because by the time the camera arrives, the first photograph has already been taken. In other words, when the number of film shots is 1,
Taking a second photo is prohibited. If the photographing set number NsE is not 1, nothing is done and the process proceeds 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+2△EV and proceed to step #CD-75 (:CD-110,
115). If N=3, set the exposure value EV to be overexposed by 2ΔEV as EV=EV−3ΔEV, and set the number of shots in the shooting set to N3. Determine whether T is 3 or not. 3, set release prohibition data; if not, immediately proceed to step #CD-75 (#C
D-120 to 130). If N=4, set the exposure value EV to EV=EV+Δ4EV to set the exposure amplifier by 2ΔEV, and if N=4, set release prohibition data and proceed to step #CD-75 (#CD-150).
. Therefore, when shooting with exposure shift using an auto bracket card, the exposure is correct, ∆EV over, ∆EV under, and 2.
This is done in the order of ΔEV over and 2ΔEV under.

[Effects of the Invention] As explained above, the present invention provides a touch panel on the dot matrix display section in a visible state, so that the area occupied by the display section and the setting section is not increased, and the display section is made smaller. Since you can set shooting information while looking at the displayed information, operability is improved.
