JPS61167934A - Exposure controller of camera and adapter for exposure control - Google Patents

Abstract

PURPOSE:To obtain plural exposure arithmetic functions by providing both a camera body and an adapter for exposure control with the exposure arithmetic functions, and performing exposure control on the basis of the arithmetic result of the camera body when no arithmetic result is sent out of the adapter. CONSTITUTION:A switch S2 is a release switch which is closed by the 2nd stage of depression of a release button and when the S2 is closed, exposure control operation is started. Further, a signal line BS2 is connected from a back circuit BCKC in parallel to it and a signal for starting photographing operation is sent to the camera body when a specific number of photographs are taken under the control of the BCKC as interval photography or while the exposure is deviated from proper exposure by a constant value at each time. Further, the BCKC checks the state of the S2 of the camera body and sends data which inhibits exposure control operation from being entered to the camera body unless the S2 is on after the number of set frames are exposed by bracket photography. Consequently, photography is performed in a photographic mode that the camera body does not have.

The operation is enabled and stopped by an interrupt signal to the single terminal (INTB). FIG. 100 is a flowchart showing a specific example of the calculation subroutine No. 29 in FIG. 99. First, it is determined whether or not the bracket 7 angkunyong is selected. If it is not selected, the A7 lag is reset. If it is selected, it is determined whether the bracket function is operating. If it is not operating, the A7 Set the rug. Then, after resetting or setting the A flag,
Calculate the Ev value using data from the camera body (BD). On the other hand, if the bracket function is in operation, the Ev value determined at the start of the operation is not changed, so the process moves to the bracket calculation operation. Once the current Ev value is determined, it is then determined whether data from the meter (MET) has been taken in, and if so, it is used as an external function and the data from the meter (MET) is used as a control value. Note that when the control limit is exceeded, the limit value is used as the control value, similar to the calculation in the camera body (BD). If there is no data from the meter (MET), then determine whether the mode is M or M/LT,
If it is in this mode, the manually set Tv
, A v is output. On the other hand, if it is not the M, M/LT mode, then it is determined whether multi-7γ function is selected, and if multi-function is selected, the control Ev value is calculated based on the stored Ev value. A subroutine for this multi-function calculation is shown in FIG. 102. When in center mode, the maximum Evnax and minimum Ev of the stored Ev values.
Find min, and from these two values (E v + nax +
E vmin )/2 is calculated to control E
Find v. If it is not the center, it is determined whether it is the highlight mode, and if it is the highlight mode, the calculation of E vmax -2, 3 is performed on the maximum value of Ev stored, and the control Ev is calculated. If it is not highlight mode, then it is determined whether it is shadow mode or not, and if it is shadow mode, E n is set to the minimum value Evm'+n of stored Ev.
The calculation of n1n+ 2 and 7 is performed to calculate the control Ev. If it is not the shadow mode, it is the average mode, and in this case, the calculation is performed to calculate the control Ev. In FIG. io, when the multi-7T system is not selected, the Ev from the camera is used as the control Ev. Then, based on the obtained control Ev, P , , P
2. Calculation is performed depending on which mode is selected among P, , A, and S modes. A specific example of this calculation subroutine is shown in FIG. This operation is first performed as follows: E vmax (= T vmax + A v+*ax)

On the other hand, if it is within interlocking, 7. Perform operations according to the order shown in the low chart, calculate the control value, reset the out-of-interlock flag, and main routine (Figure 100)
Return to In addition, in the camera body (BD), when the calculated value exceeds the control limit, the limit value is used as the calculated value and the set value is output as is, but in the back circuit, the limit value is used as the set value and the next The set value was changed by recalculating the EV and limit value. Also, when in program mode, the limit aperture value can be set (not the maximum aperture value or the maximum aperture value). When the control TV and A v are determined, 7 pufferfish A becomes “1”
If it is set to 1", it means that the bracket function is selected and no calculation is being performed, and the operation shifts to the calculation operation for brackets.Also, even while the bracket function is operating, the next Moving on to the bracketing calculation for photographing M.
, determines whether it is M/LT mode, and if it is M or M/LT mode, shifts the fringe value by the number of frames (number of times of next shooting). JJ and reset A7-7. On the other hand, in the P, -P2-Ps, A, and S modes, Ev is shifted by the amount of 7 lems, the A7 lag is removed by 77, and the process moves to the calculation subroutine for TV and Av. Next, the bracket) 7y angle is selected, shooting for the set number of frames is completed, and the signal line (BS) is selected.
2) is "Low". And “Low”
If the above conditions are not met, a release disable signal is set to prevent the photographing operation, and if the above conditions are not met, the release disable signal is reset and the process returns to the main routine. FIG. 105 is a 70-chart showing the operation of the current microcomputer (CAMC). First, the signal line (IP) on the camera body (BD) goes low when the exposure control starts.
, an interrupt operation by the interrupt terminal (INTA) starts. Then, in step STI, a timer interrupt (ls
ec) and moves to Sr1. In step ST2, it is determined whether the switch (SCN) is "ON" or not. If it is "ON", the interval and M/LT operations are not performed and the process moves to step 7 step 5T20. If SCN is "OFF", it is determined whether it is interval shooting, and if it is not interval shooting, then it is determined whether the M/LT mode is selected.And if it is M/LT mode, the signal line CB
S,) is entered as "Lou+", and if the mode is not M/LT mode, the process directly proceeds to step 7, step 5T20. When it is determined in step Sr1 that it is interval photography, the remaining time until the start of interval photography is reset, and the signal line (B S 2) is set to "Low". Then, the register rFR in which the number of frames is set is 7.
"1" is subtracted from "1", and if there is no register IFR, it is 0"
If not, the process moves to step 5T20. on the other hand,
If the contents of register IFR are “0”, then “1” is subtracted from register rGR where the number of groups is set.
aQ". If it is "0", set the interval end signal and go "O".
If not, set the remaining time. And M/LT
If it is not M/LT mode, the signal line (BS 2) is set to 'High', and if it is M/LT mode, the signal line (BS 2) is set to 'High'.
remains as "LoI11" and proceeds to step 5T20. Then, it enables interrupts to the interrupt terminals (INTA) and (INTB), and determines whether the 7lag TIF is "1".If the 7lag TIF is "1", a timer interrupt is generated during this operation. Therefore, the TIF is reset to "0" and the operation proceeds from step 5T45.On the other hand, if the 7-lag TIF is "0", the operation is stopped.The control microcomputer (CMC) sends a signal for data exchange. When the line (CSCA) is set to “Low”, the calendar microcomputer (CAMC) connects the interrupt terminal (INT) from 5T25.
Perform the operation according to B). 5T25 enables a timer interrupt, and then determines whether to output or input data by determining the state of the signal line (Ilo). For data input, the control microcomputer (C
MC). Then, if the M/LT mode is selected and the M/LT mode is not in operation, set the exposure time data, and if the M/LT mode is selected and the setting is None 1, or if the cuff seat is in M/LT mode, leave it at 5.
The process moves to step T30. In step Sr10, it is determined whether the interval function is selected and the motion layer is reached. If the interval function is selected and is in operation, leave it at 5T.
Move to step 20. On the other hand, when the interval function is selected and the operation has not started, the number of frames is set in the register rFR, the number of groups is set in IGH, the time interval between groups (remaining time), and the start time are set. Move to the next step. Sr.
When it is determined in step 26 that data is to be output, the aforementioned data is sent to the control microcomputer (CMC) and the process moves to step 5T20. When a timer interrupt occurs every second, steps 5T40 and 41 occur.
The operation starts from the interrupt terminal (INTA), (I
If such an operation is not being performed or those (INTA)
When the operation (INTB) is completed, the operation starts from step 5T45. In step 5T45, the calendar is rewritten by increments of 1 second. Then, it is determined whether the M/LT mode is operating, and if it is, "1"' is subtracted from the set seconds (Tv timer), and it is determined whether the Tv timer has reached "O". If θ'' has not been reached, the process directly proceeds to step Sr12 (INTA). (INTB), the operation is stopped by allowing interrupts by the timer. Meanwhile, in step 5T48, the contents of the Tv timer are set to "0". If so, set the signal line (BS2) to “H”.
The camera body (BD) starts running the trailing curtain as "high" and moves to step 5T62. If it is determined in step 5T46 that the M/LT mode is not in operation, then interval shooting operation is performed. If it is not interval shooting, the signal line (BS2) is set to "High" and the process moves to step Sr12. ) may be repeated, resulting in a non-operation state (stopping operation).In this case, M/LT sets the signal line (BS2) to "High" to stop the interval, and controls the camera's exposure control operation. When it is determined in step 5T55 that the interval function is selected, the process moves to step 5T56, where it is determined whether it is 1 minute before the start of one group shooting, and if it is 1 minute before, the signal line ( BS,) to “Lo
U+'' pulse is output to start the camera body (BD) and start the column/pressure operation of the 7 runcillator (FL).In this case, the signal line (BS2) is
Since iH1+'' has already been output, calculate the time until the start and move to step 5T62.On the other hand, 5T56
If it is determined in the step that it is not one minute before, it is then determined whether it is the start time for one group's shooting, and if the start time has been reached, the signal line (BS
2) is set as "LOIll" and moves to step 5T62. On the other hand, at step 8 before or after the start, it is determined whether "Lou+" is output to the signal line (BS2), and if "Low" is output, one group is photographed. Since it is in operation, it immediately moves to step 5T62. On the other hand, the signal line (B S 2) is
If “high” is output, it is before starting the shooting operation of interval shooting or between groups,
In this case, the remaining time until the start is calculated and the process moves to step 5T62. Next, display microcontroller (DMC), LCD segment driver (SD), LCD common driver (CD), LC

I will explain the graphic de spray bronc made up of. First, the control microcomputer (CMC
Based on the transfer lock (DCK2), the data (4 bits) shown in Table 2 is transferred from the display microcontroller (DMC) via the data bus (DBUS2) to the display microcontroller (DMC).
DMC) is converted into data for graphic display, and L
It is serially transferred to the CD segment driver (SD). LCD segment driver (SD) is R for LCD display.
It has a built-in AM, and 1 bit of data in this LCD display RAM corresponds to lighting or non-lighting of 1 dot on the liquid crystal display (LCD). After the graph ink display data is transferred to the LCD segment driver (SD),
RAM for LCD display is stored in RAM for LCD display.

CD) is an LCD that uses a built-in oscillator to generate the timing signals necessary for display, and also automatically scans the common signal of the liquid crystal display (LCD) in accordance with the display duty.
The common scanning signal (CM T ) is sent to the liquid crystal display section (LCD).

) and the LCD common driver (CD). The above is an outline of the operation until a graph ink pattern is displayed on the liquid crystal display (LCD) based on data from the control microcomputer (CMC). Below is a 70-chart of the display microcomputer (DMC). A more detailed explanation will be given with reference to the following. First, from the control microcomputer (CMC) to the display microcomputer (D
The display microcomputer (DMC) starts operating by the signal line (DEN) to the MC), and power supply starts.
The reset routine shown in FIG. 106 is started (step ■). Step 1 Initialize the LCD segment driver (SD) and connect the LCD segment driver (SD) to the LCD segment driver (SD).
) is turned off (all lights off). In step 7, it is determined whether the mode is full lighting mode or not, and normally the system enters an interrupt standby state in step (2). This determination of whether or not the full lighting mode is used is for a disconnection test at the factory.When the full lighting mode is selected, all lighting data is output to the LCD segment driver (SD). Turn on the display section (LCD) and stop the system clock in step (2). If it is not the normal mode, that is, the full lighting mode, the CPU enters the interrupt standby state of step (2) and waits for an interrupt from the control microcomputer (CMC). Figure 107 The imprint routine is a step 7 for displaying an imprinting indicator (“IMF”) for a certain period of time during imprinting.
This is to set the lag, and the imprint signal from the camera (
rp) to start (step ■), step ■
After the Renostar is saved at step [stock] and the "I MF" display flag is sent at step [stock], the renostar is returned at step 2, and the current main routine is returned at step @. The main routine in Fig. 108 is executed by a control microcomputer (CM C
) to the display microcomputer (DMC) until all processing in the display microcomputer (DMC) is completed in step ■).
Prohibit restart of the main routine, input the transfer data from the control microcomputer (CMC) shown in Table 2 in step 2, check the power supply voltage in step 2, and if the power supply voltage is below a predetermined value, step O Then, set the power supply voltage change flag (B, C17 lag). In steps ■ to step 29, the control microcomputer (CMC)
4 graphics display data are decoded from the transferred data. This decoding is performed first on the character display section (Fig. 6-(16)
) is performed (step ■, mode name display, IN
PUT display and 0UTPUT display are converted into graphic display data by referring to the table corresponding to each display content, and this data is sent to the LCD segment driver (
SD) and this LCD segment driver (
The data is written to the LCD display RAM in SD (step 2). Subsequently, the index indicating the range from control and the mode display section (18) in FIG. 6 are decoded in step [phase] and output to the LCD segment driver (SD) (step 21). Next, the index showing the shutter speed value, Fig. 6-(22
), an indicator indicating the aperture value, Fig. 6-(23), and a symbol indicating that each function is in the execution state, rjS6
Figure 21 is coded into graphic display data (step 22). In step 23, the B, C, and 7 lags determined in step ■ are tested, and if B, C
, 7 lags are set, a battery check display (B, C, display) is displayed in FIG. 6-(24) (step 24). If the B, C, and 7 lags are not set, depending on which function is selected on the external display, an operation corresponding to that function is performed in step 25, and furthermore, this function also decodes itself. 26), the graph ink display data from steps 22 to 26 is output to the LCD segment driver (SD) at step 27; Here, the calculation according to the function selected on the external display in step 25 will be explained in detail. When the exposure function is first selected, first, in order to draw the Ev line (Figure 6-(25)), find the appropriate aperture value for each shutter speed value while changing the shutter speed value in order. . After that, exposure mode (P,, P2゜P 3-S-A4M

The setting line for M/LT mode can also be drawn using exactly the same procedure as for M mode.The above is the calculation method of the graphic display section in the exposure function.Next, on the external display, The calculation of the graphic display unit when the function is selected will be described. At this time, the index of -6 to +6 (hereinafter abbreviated as ΔEvx) indicating the range from the control is already The display unit (LCD) is decoded so that it lights up, and the indicator showing the shutter speed value, Figure 6-(22), and the indicator showing the aperture value, Figure 6-(23), go out. In Table 4, let the automatically controlled Ev value be Ev, c, the Ev currently being measured be Evo, and the number of stored data be n. Plot the point P.

The above is the calculation method of the graphic display section in the multifunction. Next, the bracket function is selected on the external display. We will explain the calculations on the graphic display when
As with the multi-function, in step/b [phase] in Figure 108, the liquid crystal display (LCD) is decoded so that it lights up once. In Table 4, the current point is △EvCONT, and the setting start point is decoded. △

Output to segment driver (SD). In this way, when all graph ink display data is decoded and serially sent to the LCD segment driver (SD), the liquid crystal display (LCD) is turned on (step 30), and the display microcomputer (DMC) ) ends the processing loop 1. Then in step 31,
Interrupt signal (C3DM) from control microcomputer (CMC)
When the display microcomputer (DMC) enters the standby state and receives the body insertion signal (CSDM) again, it starts the main routine again and enters the process for displaying large graphics from step ① in Figure 108. That's why. As described above, a graphic pattern is displayed on the liquid crystal display (LCD) according to data sent from the control microcomputer (CMC) to the display microcomputer (DMC). In the buck circuit (BCKC) shown in Fig. 98, power is supplied to the current microcomputer from two 3-volt power batteries (B), and the control and display microcomputer (CMC),
(DMC) is powered by four 6-volt power batteries (A). And display microcomputer (DMC)
) is checking both (A) and (B) power batteries. When the power supply battery (A) is full, the symbol (A) is displayed on the graphic display section (24) as shown in Fig. 117.
and four batteries are displayed, and when the power source battery (B) is not working, the symbol (B) and two batteries are displayed as shown in FIG. 118. Here, P, a line with a slope in mode (Fig. 109A
To explain how to draw the shutter
The method of displaying a line with a slope of speed value 2 aperture value = 1 = 2 is as shown in Fig. 119 (a), (b),
There are 39 possible letters (c). That is, in this embodiment, the minimum display step of the liquid crystal display (LCD) is 0.5 Ev steps in both the shutter speed direction and the fringing direction, so a point is always displayed every 0.5 Ev step of the aperture value. If so, it can be displayed in #5119 diagram (a) or (b). The difference between FIGS. 119(,) and (b) is due to the shutter speed value and the rounding method of the aperture value during display. If displayed in this way, it is extremely difficult to understand the slope of 1:2 between the shutter speed value and the aperture value in P1 mode. Therefore, in this embodiment, as shown in FIG. 119 (C), only the points for each IEv step of the aperture value are displayed,
The points in between are not displayed. This results in
The slope of the aperture value relative to the shutter speed value is clear. In the P3 mode, the display as shown in FIG. 8 is displayed for exactly the same reason. Next, how to draw the EV line (25) in FIG. 6 will be explained. In this embodiment, the display range of the liquid crystal display (LCD) is set such that the shunter speed value is Tv≦11, and the aperture value is Av.

Only the range of 5 is displayed. However, the setting line (Fig. 6-(26)) is Tv≦11°Av

), step ■), do not plot if it is outside the range. In step ■, Tvx is incremented by IEv step, and in step ■, Tvx>Tv+aax (Tv=11) is determined.
If No, return to step ■ and follow steps ■～■
Repeat. If YES, that is, Tv>Tv□ax, the process proceeds to step (2) and ends. In addition, Tvx
The increment step may be 0.5 Ev step. [According to the present invention as described above, by attaching to the camera body an adapter that has calculation functions other than those provided in the camera body, it is possible to use shooting modes that are not provided in the camera body. This makes it possible to take pictures with the camera, creating a highly expandable camera system.Furthermore, the adapter is equipped with arithmetic functions, so the camera body has the ability to handle the i-Shadow mode that is planned for the camera itself.
