In FIGS. 10A and 10B, reference numeral 431 denotes a photosensitive layer having a lattice shape, and the photosensitive pixels 432 are arranged between the photosensitive pixels 432 arranged in a matrix. Similarly, it is attached on the insulating film 433 and electrically insulated from the photosensitive pixel 432. Further, as shown in FIG. 6C, the photosensitive layer 431 is divided into a plurality of sections, for example, a central section 431a and a peripheral section 431b to form a photometric pattern. Then, based on the photometric signals from both of the sections 431a and 431b, for example, switching between center-weighted photometry and average photometry is possible. As will be described later, the CCD 43 is divided into 15 areas that are electrically connected to each other, and the photometry and the dimming are performed in combination. By configuring the CCD 43 in this way, of the light that enters the CCD 43, the light that enters the photosensitive pixels 432 is photoelectrically converted and accumulated in each photosensitive pixel 432, and the accumulated charges are transferred to form image data. On the other hand, the light that is taken out and is incident on the grid-shaped photosensitive layer 431 is converted into a photometric signal in each area corresponding to the brightness of the entire image and is output.

Returning to FIG. 9, the monitor 47 is a two-dimensional color LCD whose aspect ratio is set to 9:16.
And the like, and displays an image picked up by the CCD 43 or a stored image in a frame memory or the like described later. In addition to the above-mentioned image display, the monitor 47 can display necessary marks, shutter speed Tv, aperture value Av, and other shooting conditions, as well as a frame line indicating a selected aspect ratio, a specific color, and the like by superimposing.

Split formation (see Figure 11)
It is composed of an infrared area sensor. Infrared rays are used to eliminate the effects of sunlight.
The line-of-sight detection is such that the light emitted from the infrared LED is reflected by the eyes of the photographer looking into the finder 28 and returns, and the line-of-sight area of the infrared area sensor is used to make a determination. . For example, a known line-of-sight detection method performed by using the first Purkinje image, or by using the first Purkinje image and the fourth Purkinje image, or another known method may be adopted.

Line-of-sight areas are evenly divided into rows. Of these areas, the width of one line at the center substantially matches the aspect ratio of the Pano mode in the film photographing mode. This is because in the Pano mode, the metering, AF, and dimming are performed appropriately by using one central row. Therefore, the gaze detection is the first to fifteenth.
This is performed by determining in which of the 15 line-of-sight areas (AR1 to AR15) the reflected light from the photographer's eye is received. The area AR16 is an area outside the line-of-sight detection area frame 19.

Focus detection areas AF1 to AF15 (not shown) are set to positions corresponding to AR1 to AR15 of the line-of-sight area. In addition, the photometric area AE
1 to AE15 (not shown) are also in the above areas AR1 to AR15

As shown in the figure, shooting mode 1 is a film shooting mode, shooting mode 2 is an electronic still shooting mode, and shooting mode 3 is a moving image shooting mode.

FIG. 13 is a diagram for explaining the display contents on the monitor 47 of the aspect ratio in the film photographing mode and the aspect ratio in the electronic still photographing mode or the moving image photographing mode. The horizontal direction is classified into H mode, N mode, and OFF mode in the electronic still shooting mode / moving image shooting mode and is divided according to the presence or absence of film, and the vertical direction is the aspect mode in the film shooting mode. The presence / absence of a film can be detected inside the camera body 20 by a film presence / absence sensor FD (see FIG. 1) such as an optical sensor or a mechanical switch provided in the film loading section.

When the film is present, the moving image shooting mode and the electronic still shooting mode are the H mode, and the film is the Pano mode, two horizontal frame lines are displayed in the frame 18, and two horizontal frame lines are displayed. The area between them indicates the range of the panorama. If the film is in L mode, the aspect ratio is 2:
Two vertical frame lines are displayed at the position of 3. If the film is in H mode, no frame line is displayed in the frame 18. In addition,
The captured image is displayed in the frame 18.

If the movie shooting mode and the electronic still shooting mode are the N mode and the film is the Pano mode, two vertical frame lines showing the 3: 4 N mode and two horizontal frames showing the Pano mode. A line is displayed, and the non-display range within that line, that is, the four corners (hatched portions) of the frame 18 are displayed in a specific color (including colorless), and image display is prohibited. If the film is in L mode, then this L mode is also shown 2:
Two vertical frame lines 3 are displayed, and both sides (hatched portions) of the vertical frame line 3 are displayed in a specific color (including colorless), and image display is prohibited. If the film is in H mode, it will be 3: 4 in frame 18.
The two vertical frame lines of No. remain displayed.

When the moving image shooting mode and the electronic still shooting mode are off, vertical frame lines and horizontal frame lines are respectively displayed to show the display range corresponding to each mode of the film, and the outside of the display range (hatched portion) is specified. Colored (including colorless) prohibits image display. When the film is in the H mode, no frame line is displayed in the frame 18.

On the other hand, in the case of no film, no frame line is displayed if the moving image shooting mode and the electronic still shooting mode are the H mode, and 3: 4 is shown in the N mode.
A vertical frame line of the book is displayed, and both sides (hatched portions) of the book are given a specific color (including colorless).

In this way, by displaying the frame line and the specific color according to each mode, the aspect ratio in the film photographing mode and the aspect in the electronic still photographing mode or the moving image photographing mode can be obtained only by looking at the monitor 47. The ratio mode can be recognized.

The display on the monitor 47 does not change regardless of the vertical / horizontal position of the camera posture, but the body display unit 24 displays the posture according to the posture. 14A and 14B show the display contents on the body display unit 24 in the vertical position. FIG. 14A shows the case of the H mode, and FIG. 14B shows the case of the N mode. Vertical / horizontal position detection is, for example, T-shaped, and an appropriate amount of conductive liquid is enclosed in a tube with electrodes formed at the three ends, and this tube is placed in a vertical plane in the normal posture of the camera. The attitude detecting means HV (see FIG. 1) that automatically detects the vertical and horizontal attitudes by electrically detecting which electrode is electrically connected to which electrode according to the attitude of the camera.
Is used. Then, image processing is performed based on the detection result, and the processed image is displayed in the frame of the body display unit 24 shown in FIG.

The display of the photographing mode is performed only in the mode that is selected and set. For example, when only the moving image shooting mode 3 is selected, only the mark indicating the magnetic storage medium 52 is displayed. On the other hand, for example, when all of the shooting modes 1 to 3 are selected, all of them are displayed.
The mark indicating the post-confirmation display mode 4 is displayed when the still image display mode is selected. When the specific mode is not selected, for example, when the film mode (hereinafter, referred to as “silver salt still shooting mode” for explanation) and the electronic still shooting mode are not selected, for example, the switch S ₁ is pressed to instruct them. When the switch is turned on, the marks representing the unselected silver salt still shooting mode 1 and electronic still shooting mode 2 blink.

Further, the shutter speed TV and the aperture value A
As for the display of V, the shutter speed TV and the aperture value AV are displayed regardless of whether or not shooting is performed when the silver salt still shooting mode and the electronic still shooting mode are selected. On the other hand, when neither the silver salt still shooting mode nor the electronic still shooting mode is selected, that is, when only the moving image shooting mode is selected, neither the shutter speed TV nor the aperture value AV is displayed. As a result, unnecessary displays are turned off, which eliminates the annoyance on the screen and saves power.

[0067]

[Table 1]

FIG. 21 shows an interrupt routine executed when the switch S ₁ , the recording start switch S _REC or the grip switch S _G is turned on. When an interrupt occurs, the microcomputer (μC1) 1 resets all flags and prohibits other interrupts to this flowchart (# 2, #
4). Subsequently, data indicating the operation states of various switches is input (# 6), and a subroutine "switch data input" is executed to perform control according to those switch operations.

FIG. 22 shows the "switch data input" subroutine. First, it is determined whether the transceiver TX is attached to the camera body 20 and the switch _SREM is turned on (# 30). If the switch S _REM is on, the switch data sent from the transmitter / receiver Rx is stored in the internal RAM of the microcomputer (μC1) 1 because it is remote control (# 32), and if the switch S _REM is off, All the switches on the camera body 20 side are monitored, the monitoring result is stored in the internal RAM (# 34), and the process returns. Any subsequent detection of the state of the switch is determined by the contents stored in this internal RAM.
The vertical / horizontal position data of the camera is also detected as switch data and stored in the internal RAM.

Returning to FIG. 21, next, based on the switch data stored in the internal RAM, it is determined whether or not this interrupt is caused by turning on the switch S ₁ (#
8). If the switch S ₁ is on, the process proceeds to the "S ₁ ON" subroutine (# 10). If it is not on, it is judged whether or not the switch _SREM of the transceiver TX is turned on (# 12), and if it is on, the " _SREM " subroutine (# 14) is _executed to perform this control. If it is executed and the switch S _REM is not turned on, it is determined whether or not the moving image shooting switch S _REC is turned on (# 16). If the moving image shooting switch S _REC is turned on, the moving image subroutine "REC" is executed (# 18), and if it is not turned on, the "eyepiece" subroutine (# 20) is executed. Go to # 22. In # 22, the transistor Q1 is turned off in order to stop the power supply to the CCD / monitor / recording unit 10 and the like, and the interrupt to this flowchart is returned to the enabled state, and then stopped (# 24, # 26).

FIG. 23 shows the " _SREM " subroutine. First, subroutine "S1ON" to be described later is executed (# 40), whether the switch S _REM transceiver TX is on is determined (# 42). If it is turned on, a flag SREMF indicating this is set (# 44), and the process returns. If it is not turned on, the process returns as it is.

FIG. 24 shows the "eyepiece" subroutine. First, it is determined from the eyepiece flag SGRF whether or not eyepiece detection is performed (# 50). When the eyepiece detection is not performed, the count value N for timing is returned to "0", and the eyepiece flag SGRF indicating that this flowchart for eyepiece detection is executed is set (# 52, #). 54). Next, microcomputer (μC1)
1 turns on the light emitting element 291 of the eyepiece sensor 29 for 10 msec, and inputs data from the light receiving element 292 during that time (# 56, # 58). Then, it is determined whether or not there is light reception data (# 60). If there is no light reception data, the count value N is incremented, and then N =
It is determined whether or not it is K _N (# 62, # 64). N = K _N
If so, it is assumed that 2 seconds have passed, and the eyepiece flag SGRF
Is reset (# 66) and the process returns. On the other hand, N =
If not K _N , return to # 56.

If there is light reception data in # 60, it is determined that the photographer is looking into the finder 28, the transistor Q1 is turned on, and power is supplied to various circuits (# 68). Then, after waiting for 10 msec for the stabilization of the photometric and dimming circuit 9, the photometric data is captured (# 70, # 72). Then, the exposure calculation is performed from the photometric data in # 72 (# 74), and then A
F1 control is performed (# 76), then 100 mse
Only c is waited (# 78).

FIG. 25 shows the "exposure calculation" subroutine. In the exposure calculation, it is first determined from the result of the shooting mode setting whether the shooting mode is one of the silver salt still mode and the electronic still mode (# 110, # 11).
2) If both modes are not set, data that does not display aperture value (AV) / shutter speed (TV) is set (# 114), and the flow returns without performing exposure calculation.
On the other hand, if the shooting mode is either the silver salt still mode or the electronic still mode, the process proceeds to # 116. # 1
At 16, the film sensitivity reading device 6 reads the sensitivity SV of the loaded film. The exposure value EV is obtained by adding the photometric value BV to this (# 118), and then the exposure correction described below is performed (# 120). Furthermore, the exposure compensation amount ΔEV _AMB at that time for constant light and the exposure compensation amount Δ during preview
_Re-calculate the exposure value EV by adding EV _AMBPV (# 12
2). In addition, the exposure amount (ΔEV _FL ) + (ΔE) of the flash light amount that was exposure-corrected during the exposure correction and the preview.
V _FLPV ) is also corrected, and this variable voltage source VR is fed back to change the flash light amount, that is, as the correction of the dimming amount (# 124). The light emission amount itself may be adjusted by this correction amount.

Then, the exposure mode is discriminated (# 1
26), in the P mode, it is determined whether or not the flash is mounted (# 128), and if the flash is mounted, FL exposure calculation is performed based on the exposure value (# 13).
0) and AV / TV (aperture value / shutter speed) are required. If the flash is not attached, the exposure calculation I or II for constant light based on the constant light is performed based on the presence or absence of the recording mode determined based on the result of the shooting mode setting (# 132) (# 134). , # 136), AV
/ TV is required.

FIG. 26 shows an AV / TV program diagram. In this figure, the exposure calculation I for stationary light is represented by a diagram and the exposure calculation II for stationary light is represented by a diagram. ..
In FIG. 26, the diagram is such that the shutter speed is 1/60 between the minimum value and the maximum value of the diaphragm, and the shutter speed changes at both ends of the diaphragm according to the brightness. This diagram is adapted to the field (screen scanning) period of the television scan, and is used to control the aperture and shutter speed while shooting only a moving image or during shooting preparation. 1/250 when the maximum aperture is reached
The maximum aperture value is controlled up to the shutter speed of. This value 1/250 is set as the limit of the range that can be seen on a television as a moving image. The diagram is for still shooting when there is no video recording, and the aperture and shutter speed change at the same rate with respect to brightness. Further, a program diagram for high speed, a program diagram for prioritizing the aperture open effect for portrait, etc., or a program diagram for setting a large depth of field may be adopted. The line diagram is a program line diagram for still shooting during recording, which connects 1/250 and the maximum aperture value. The purpose of this is to reduce the aperture change when moving from the movie display mode to still shooting, to increase the shutter speed to reduce camera shake and image blur, and to satisfy the continuity of movies. Therefore, the shutter speed is held down to 1/250.

If the exposure mode is the A mode, the S mode or the M mode, the well-known exposure calculation is performed to obtain the AV / TV (# 138, # 140,
# 142), and returns.

FIG. 27 shows the "AF1" subroutine. The AF1 process automatically selects the main subject when the area detected by the line of sight is not set, and
The lens is driven according to the defocus amount of the area selected from the five areas. First,
The image data stored on the CCD / monitor / recording unit 10 side is input to the microcomputer (μC1) 1 in response to a read instruction from the microcomputer (μC1) 1 (# 160), and 15 image data are input based on the input image data. Each defocus amount of the area is calculated (# 162). Here, it is determined whether the shooting mode is the silver salt still shooting mode (# 16
4) If so, then the aspect mode is Pan
It is determined whether or not it is the o mode (# 166). Pano
If it is the mode, the area is selected from the defocus amounts from the areas AR6 to AR10, with the object at the closest distance from the camera body 20 as the main object (# 1).
68), the lens is driven based on this defocus amount (# 172), and the process returns. Areas AR1 to AR when the silver salt still shooting mode is not set, or when the silver salt still shooting mode is not Pano mode
Of the defocus amounts from 15, the area closest to the camera body 20 is selected as the main subject (# 170), and the lens is driven based on this defocus amount (# 170). 172) and returns.

Returning to FIG. 24, next, at step # 80, shooting preparation is performed. This "shooting preparation" subroutine is shown in FIG.

Next, switch data for selecting various controls is input (# 182). Based on this switch data input, shooting mode setting, aspect ratio setting,
Exposure mode setting and AV / TV setting are performed (# 1
84- # 190). Then, based on the set area, the switch data, and the set control value, the AF / AE
Processing (including exposure calculation) is performed (# 192), and when these data are output (# 194), the process returns.

If the switch S _REM is off, the image displayed on the monitor 47 is checked through the finder, so that the process proceeds to step # 202 to control the line-of-sight detection.

In # 202, the light emitting section (infrared LED) in the visual axis detection circuit 2 is turned on for 10 msec, the emitted light is reflected by the eye of the photographer looking into the finder 28 and is received by the infrared area sensor. The received light data is taken in (# 204). The line-of-sight area seen by the photographer's eye is detected from the captured data, and the detected line-of-sight area is captured as an area ARN (N = 1 to 16) (# 206).

Next, it is judged whether the photographing mode is the silver salt still photographing mode (# 208), and if so, then it is judged whether the aspect mode is the Pano mode (# 210). Here, in the Pano mode, it is determined whether or not the line-of-sight detection area is ARN6 to ARN10 (# 212). If the silver salt still image capturing mode is not set, or if the silver salt still image capturing mode is not Pano mode, it is determined whether or not the line-of-sight detection area is ARN16 (# 214). Gaze detection area is ARN
If it is not 6 to ARN10, or if it is ARN16, that is, if the area cannot be detected within the set area, the process proceeds to # 216. In # 216, a timer flag TMF for measuring the time between them is set.

02). If the exposure mode change switch S _MD is turned from off to on, it is determined that the setting mode is entered, and the flag MDF is set (# 304). On the other hand, if it is not from off to on, the process directly returns. . #
If the flag MDF is set at 300, the exposure modes A, M, S, and P are cyclically changed in this order according to the operation of the front dial 33 or the rear dial 34 (# 306). Next, it is determined whether or not the exposure mode change switch S _MD is turned from off to on (# 308),
If it is changed from off to on, it is determined that an operation is performed to exit this setting mode, and the flag MDF is set.
Is reset (# 310), and conversely, if the operation from off to on has not been performed, the process directly returns.

In the "AV / TV setting" subroutine, first, the flag MDF indicating the exposure mode setting, the flag ECRF indicating the exposure correction by the constant light, the flag ECR _FL F indicating the exposure correction by the flash light and the white balance correction are set. It is determined whether or not the respective flags WBF are set (# 320 to # 326), and if either is set, it is determined that the mode is set, and the process directly returns. If neither is set, the exposure mode at that time is determined (# 32
8) The following processing is executed. If the exposure mode is the P mode, so-called P shift processing is performed in which the shutter speed TV increases or decreases in the opposite direction in response to the increase or decrease in the aperture value AV (# 330). If the exposure mode is the A mode, the aperture value AV is changed (# 332). If the exposure mode is the S mode, the shutter speed TV is changed (# 334). If the exposure mode is the M mode, the aperture value AV is changed by operating the front dial 33, and the shutter speed TV is changed by operating the rear dial 34 (# 3).
36, # 338). Then, after this processing, the process returns.

In the "AF / AE" subroutine, first, the photometric data is input (# 350), and then the G in the R, G, B image data is input from the microcomputer (μC2) 100.
(Green) data is input (# 352). Next, it is determined whether or not the switch _SREM of the transceiver TX is turned on (# 354), and if it is turned on, the line-of-sight detection is not necessary as described above, and therefore the temporary focus detection of AF1 is performed and the photometry is performed. The value BV is fetched and the exposure calculation is executed (# 360 to # 364). If the switch S _REM is not turned on, the switch S _SDI (line-of-sight operation member 3
Based on the operation 0), it is determined whether or not the area flag ARF is set (# 356).

If the area flag ARF is not set, it is next determined whether or not the area reset flag RSTF is set (# 358). When the area reset flag RSTF is set, AF,
Since it is not known to which area ARN the AE processing should be performed, A is set until the area AR is set next time.
In order to lock the F / AE, # 360 to # 364 are skipped, the focus flag AFEF indicating the focus is reset ((#
366), and returns. In # 358, when the area reset flag RSTF is not set, it means that the area AR has never been set since the power was turned on.
In this case, AF and AE are always applied to various subjects.
I think that it is better not to lock AF / AE so that the processing can be performed, and the temporary focus detection of AF1 described above is repeatedly performed (continuous AF), and the photometric value BV is taken in each time and the exposure calculation is further performed. After that, the focus flag AFEF indicating the focus is reset (# 360 to # 36).
4) Return.

On the other hand, if the area flag ARF is set by the switch S _SDI (line-of-sight operating member 30) in # 356, it is determined whether or not the switch S ₁ is turned on (# 368). If the switch S ₁ is not turned on, A
The flag AFEF indicating the focus is reset so as to make the F mode continuous (# 370). Switch S
_{If 1} is on, the process directly proceeds to # 372.

In # 372, it is judged whether or not the focus flag AFEF indicating that the focus is once set is set. If it is set, that is, once the focus is set, focus detection is not performed again (one Shot AF) and return. If not set, focus detection is performed, and it is determined whether or not focus is achieved based on the result (#
374, # 376). If out of focus, the taking lens 211 is driven based on the result of focus detection (# 378),
Return to # 374 again. Then, if it is determined to be in focus at # 376, a focus flag AFEF indicating that focus has been set is set, and then photometry is performed (# 380, # 38).
2) Return.

The "focus detection" subroutine will be described with reference to FIG. 35, and the "photometry" subroutine will be described with reference to FIG.

In the "focus detection" subroutine, the defocus amount DF _N in the area AF corresponding to the set area ARN is calculated and the process returns (# 39).

[Table 3]

In the "photometry" subroutine, first, the subject distance DV is calculated based on the lens extension amount, the focal length f is further taken in, and the image magnification β is calculated from the subject distance DV and the focal length f. (# 400 to # 4
04).

Next, it is determined whether the shooting mode is the silver salt still shooting mode (# 406), and if it is the silver salt still shooting mode, it is determined whether the aspect mode is the Pano mode (# 408). In the Pano mode, it is determined whether the image magnification β is equal to or larger than the predetermined value K1B (# 410). This value K1B is set in consideration of the enlargement magnification at the time of printing, and is set so that the enlargement magnification is about 4 times as large as that in the L mode, and is a value smaller by that amount than the image magnification described later.

If the image magnification β is greater than or equal to the predetermined value K1B, the total of the determined area ARN and the area sandwiching the area is 3 in total.
The average value C of the photometric values of each area is set as the photometric value Bv (# 4
12), the exposure calculation is executed based on this value (# 4
22). On the other hand, if the image magnification β is less than the predetermined value K1B,
The average value D of the areas ARN6 to ARN10 is set as the photometric value Bv (# 414), and the exposure calculation is executed based on this value (# 422).

If the silver salt still photography mode is not set, or if the silver salt still photography mode is not the Pano mode, the obtained image magnification β is the predetermined value K in # 416.
_It is determined whether it is _B or more. If the image magnification β is equal to or _larger than the predetermined value K _B , the photometric data of the AR area is output from the CCD / monitor / recording unit 10 based on “Photometry A” in Table 3 above, and the average value thereof is calculated ( # 418, # 42
2). On the contrary, if the image magnification β is less than the predetermined value K _B , Table 3
Based on “Photometry B” of No. 3, photometry data for the AR area is output as described above, and exposure calculation is executed from this photometry data (# 420, # 422). In the above, when the image magnification β is small, the photometric data of a plurality of areas are averaged so that the entire landscape or the like can be photographed appropriately.

Returning to FIG. 24, the "shooting preparation" process is executed.

Here, the above-mentioned "reproduction" subroutine will be described with reference to FIG. First, it is determined whether the shooting mode is the silver salt still mode or the electronic still mode, and when neither shooting mode is selected (NO in both # 430 and # 432), the preview (pre-) and post-check control are prohibited. And return. If the shooting mode is either the silver salt still image or the electronic still image, the process proceeds to step # 434 in order to control the preview and the subsequent confirmation. In # 434, the state of the flag RECF is determined, the flag RECF is set,
That is, if recording is in progress, the process returns to prohibit the preview operation and the subsequent confirmation display operation by the monitor 47. If recording is not in progress, it is determined whether or not the switch _SPV is turned on from off (# 436). If the switch _SPV is turned on from off, the "preview" subroutine is executed (# 442) and the process returns. Otherwise, it is determined whether or not the switch S _DPI for displaying the image stored in the image memory has been turned from off to on (# 438). If it has been turned from off to on, a flag indicating this is shown. DPIF is set (# 440), the "preview" subroutine is further executed (# 442), and the process returns. Switch S _DPI
If is not turned from off to on, it returns as it is.

When the "reproduction" subroutine is completed, returning to FIG. 24, it is judged whether or not the grip switch S _G is turned on (# 86). Grip switch S
_{If G} is off, proceed from # 88 to # 66 and set the flag S.
Reset GRF and exit the eyepiece routine. on the other hand,
If the grip switch S _G is on, the process proceeds to # 80.

Next, the "S ₁ ON" subroutine will be described with reference to FIGS. 38 and 39. When the switch S ₁ is turned on, it is first determined whether the shooting mode is the silver salt still mode or the electronic still mode (# 45).
0, # 452), if none of the shooting modes, warning data is set (# 454), this data is output and a warning is displayed (# 456). Then, it waits for the vertical synchronizing signal V _sync (# 458), and when this signal is input, it is determined whether or not the switch S ₁ is off (# 460). If the switch S ₁ is off, the process returns, and if it is on, the process proceeds to # 456.

On the other hand, if the photographing mode is the silver salt still mode or the electronic still mode, the eyepiece flag SG indicating the eyepiece detection.
It is determined whether RF is set (# 46).
2). When the eyepiece is detected here, the photographing preparation operation is performed (# 464), and the process proceeds to # 466. In # 466, it is determined whether or not the switch S ₂ is turned on. If the switch S ₂ is not on, it is determined whether or not the moving image shooting mode is selected in the shooting mode (# 4
68), if it is the video recording mode, the switch S for recording
Determine if _REC went from off to on (#
470). When the switch S _REC is turned from OFF to ON, it is determined that the operation for moving image shooting has been performed, and it is determined whether or not the flag RECF indicating that the moving image shooting mode is set is set (# 472). If the flag RECF is not set, the switch S is used to start recording.
_{As the REC} is operated, the flag RECF is set (# 474), and the data for instructing the start of recording is CCD /
Output to the monitor / storage unit 10 (# 476), # 4
Move to 64. On the other hand, when the flag RECF is set, the switch S is used to stop the recording during recording.
_{As the REC} is operated, the flag RECF is reset (# 478), and the data for instructing the recording stop is CCD /
Output to the monitor / storage unit 10 (# 480), # 4
Move to 64.

On the other hand, if it is not in the moving image photographing mode in # 468, or if the switch S _REC is not turned from OFF to ON in # 470, the process proceeds to # 482. In # 482, the "playback" subroutine is executed, and then it is determined from the state of the flag RECF whether or not recording is in progress (#
484). If recording is in progress, the process proceeds to # 464 and the recording operation is continued. If recording is not in progress, it is determined whether or not the switch S ₁ is turned off (# 486), and if not turned off, the timer _TH is reset and started (# 488), and the process proceeds to # 464. On the other hand, if the switch S ₁ is off, it is determined whether or not the timer T _H has counted for 5 seconds (# 490), and until the time elapses, #
Proceed to 464, and if it has elapsed, return. In addition, # 4
In 62, if the eyepiece flag SGRF is not set, this flag is set (# 492) and # 68
Proceed to (Fig. 24).

If the switch S ₂ is turned on in # 466, the process proceeds to # 494 to execute the photographing operation.

Next, the "shooting" subroutine of # 494 will be described with reference to FIG. First, the flag R
It is determined from the ECF status whether recording is in progress (#
510), during recording, the lens drive is stopped during shooting in the shooting mode of silver salt still and electronic still (#
512), proceeding to # 514, and if not recording, proceeds directly to # 514. In # 514, the control (shooting I) necessary for shooting is performed, and the winding process is further performed (# 5
16) Then, the flag AFEF indicating the focus is reset (# 518), and the process returns.

Here, the subroutine of "imaging I" will be described with reference to FIG. The data of the switch S ₂ ON is output (data output) to the CCD / monitor / recording unit 10 (# 530), while waiting for the exposure OK signal to be input from the CCD / monitor / recording unit 10 (# 5).
32). When the exposure OK signal is input, the input of the vertical synchronization signal V _sync is waited for (# 534),
When this is input, aperture control is performed according to the required aperture value (# 536). Next, an exposure start signal is output to the CCD / monitor / storage unit 10, where it waits for 10 msec until the diaphragm stabilizes (# 538, # 540). Subsequently, it is determined whether or not the silver salt still image capturing mode is set (# 542), and if it is the silver salt still image capturing mode, then exposure control, that is, shutter control (focal plane shutter 46 for silver salt).
Is performed (# 544). When not in the silver salt still photography mode, shutter control is not required and the operation is waited so that the aperture charging operation and the like are not performed during the exposure operation of the CCD 43 (# 546).

Here, the subroutine of "winding" after the end of exposure will be described with reference to FIG. First, it is determined whether or not it is in the silver salt still photography mode (# 560). If it is not in the silver salt still photography mode, winding and charging are not necessary, and the process directly returns. On the other hand, in the silver salt still photography mode, the winding of one frame of the film 45 is started (# 562), and necessary information is written in the magnetic recording unit 453 of the film 45 at a predetermined timing (# 564). ). Then, when the winding of one frame is completed, the frame feeding is ended (# 566, # 568) and the process returns.

Now, the "data writing" subroutine to the magnetic recording portion 453 will be described with reference to FIG.
First, the aspect data for the silver salt film,
The selected mode among the P mode, H mode, and L mode is recorded (# 580). Next, the color temperature information is recorded and the degree of baking is recorded (# 5
82, # 584), and returns.

Then, returning to FIG. 38, it is determined whether or not continuous shooting is performed (# 496). If continuous shooting is performed, # 464 is executed.
Proceed to. Thus, by obtaining new data for integration and AF and AE processing in the CCD 43 during continuous shooting,
It is possible to show the moving image to the photographer. On the other hand, # 4
96, if the continuous shooting, wait until the switch S ₁ is turned off (# 498), the switch S ₁ is turned off, the process proceeds to # 464.

Next, the "preview" subroutine is
This will be described with reference to FIGS. First, switch S _DPI
It is determined whether or not the flag DPIF indicating that the image is displayed from the image memory in accordance with the operation of # is set (# 590). If the flag DPIF is set, "exposure correction (PV) preview", "color correction",
Each "aspect ratio change" subroutine is executed (# 592, # 594, # 596). Then switch S
_It is determined whether the _DPI has been switched from on to off (# 5
98), if the switch S _DPI is not ON to OFF, the changed data is output to the microcomputer (μC2) 100 (# 600), and the flow proceeds to # 592.

On the other hand, if the switch S _DPI is from on to off, the flag DPIF is reset and the changed data is updated in the magnetic storage unit 453, assuming that the switch is operated to exit from this loop (# 592 to # 600). In order to do so, after the frame that has already been fed by one frame is rewound by one frame (# 604), the "winding" subroutine is executed to record the changed data (# 606). , Return after this.

If the flag DPIF is not set in # 590, the dimming start switch S _ST is turned on, the flag 2ndF indicating the second photographing is reset, and the data indicating the state of the switch S _PV is changed to CCD / Monitor circuit 1
0 (data output) (# 608 to # 61)
2). Next, the microcomputer (μC1) 1 waits for an exposure OK signal to be input from the CCD / monitor / recording unit 10 (# 614).

When the exposure OK signal is input, the input of the vertical synchronizing signal V _sync is waited for (# 616),
When this signal V _sync is input, the aperture is controlled by the control aperture value, and the exposure start signal is output to the CCD / monitor / recording unit 10 (# 618, # 620).

Next, the stabilization of the aperture is waited (# 62).
2) A signal for turning off the dimming start switch S _ST is output (# 624). Then, after waiting for a time corresponding to the exposure time (# 626), it is determined whether or not the flag 2ndF is set (# 628). Flag 2nd
If F is not set, it is next determined whether or not flash photography is performed (# 630). If flash photography, and sets the flag 2ndF to perform the second shooting (# 632), the switch S _PV instructing preview is turned on from off along with this (# 634). The data indicating the change of the switch S _PV from OFF to ON is CC
It is output to the D / monitor / storage unit 10 side (# 612),
It is used to control the monitor 47. On the other hand, when the flag 2ndF is set in # 628 or when the flash photography is not performed (NO in # 630), the focus flag AFEF is reset (# 636), and subsequently, the exposure correction for the captured image in the preview is performed. Exposure correction (# 638), color correction (# 640), data output (# 6
42) is carried out and the process proceeds to # 644. This exposure correction and color correction make it possible to know in advance the corrected image state when the image is actually taken.

Here, the above-mentioned "exposure correction" subroutine will be described with reference to FIG. First, it is determined whether or not the flag ECRF indicating the exposure compensation mode is set (# 670). If not, whether the exposure compensation switch S _{(+/-) AMB} is turned from off to on. If it is determined (# 672) and it is not turned from off to on, the process proceeds to # 682. On the other hand, if the exposure compensation switch S _{(+/-) AMB} is turned on from off, it is determined that the exposure compensation mode is entered, and the flag ECRF is set.
Proceed to 670. If the flag ECRF is set in step # 670, the exposure correction amount ΔEV _AMB with constant light is set according to the operation amounts of the front dial 33 and the rear dial 34,
Next, it is determined whether or not the exposure compensation switch S _{(+/-) AMB} is switched from off to on (# 678). If the exposure compensation switch S _{(+/-) AMB} is not turned on from off, it returns as it is, and if it is turned on from off, the flag ECRF is reset to exit this mode (# 680). , Return.

At # 682, it is judged if the flag ECR _FL F indicating the exposure compensation of the flash light amount is set. If not set, the routine proceeds to # 684.
On the other hand, if it is set, the process proceeds to # 688. Subsequent # 6
The procedure from 84 to # 692 is the same as the procedure from # 672 to # 680, and the description thereof will be omitted. However, the exposure correction amount ΔEV _FL shown in # 688 is for the flash light.

Next, the control when an operation for color correction is performed will be described. This color correction adds a correction depending on the type of film loaded, as described below.

There are various types of light sources for taking photographs. FIGS. 47 (a) to 47 (d) show a part of the spectral characteristics, and natural light in the daytime is not spectrally biased, but tungsten light has a characteristic biased in the red region. To be However, human beings are able to recognize the color of an object illuminated by tungsten light accurately because their vision is adaptive to color. On the other hand, the color film has three photosensitive layers each having a sensitivity of one of the three colors of B (blue), G (green) and R (red). Produces all colors in ratio. The spectral sensitivity of the three layers to light can be broadly divided into two types, one is a daylight type that is balanced so that normal colors can be reproduced when shooting with natural light or strobe light during the day. Yes, the other one is a tungsten type that is balanced so that a normal color can be reproduced when the image is taken with tungsten light. 48A and 48B show examples of both types of spectral sensitivity. As can be seen from the figure, since the daylight type film has a higher sensitivity to R light than the tungsten type film, a reddish photograph is obtained when shooting with tungsten light having a large amount of R component. This is because the color film is not adaptable to human-like colors. It is necessary to correct the difference in appearance due to such a film on the monitor 47 so that the finish condition can be confirmed in advance.

Next, the "color correction" subroutine is shown in FIG.
This will be described using 9. First, the flag WB for color correction
It is determined whether or not F is set (# 70
0), if not set, it is judged whether or not the color correction switch _SWB is turned from off to on (# 70).
2). If the color correction change switch _SWB is turned from OFF to ON, the flag WBF is set to set the color correction mode (# 704) and the process returns, while the color correction switch _SWB is turned OFF. If it is not turned on from, it returns as it is. If the flag WBF is set in # 700, it is determined that the color correction mode is set, and the blue and red correction amounts ΔB _C and ΔR _C are set according to the operation of the front dial 33 and the rear dial 34 (# 7).
06, # 708). Then, the color correction switch S _WB is discriminated whether turned on from off (# 710), if the color correction switch S _WB is turned from off to on,
The flag WBF is reset to exit the color correction mode (# 712), and the process returns. If not, the process directly returns.

Returning to FIG. 45, the switch S _PV is switched at # 644.
If is not turned from off to on, proceed to # 638. Exposure correction and color correction are performed while the still image is displayed (# 638, # 640). On the other hand, when the switch _SPV is turned from OFF to ON in # 644, the switch data is output (data output) to the CCD / monitor / storage unit 10 (# 646), and then the power holding timer _TH is reset and started. (# 648). Subsequently, red, the correction amount of blue [Delta] R _C, .DELTA.B _C is stored as [Delta] R _CR, .DELTA.B _CR respectively (# 650, # 652), further flag WBF, the correction amount [Delta] R _C, .DELTA.B _C is reset (# 654 , # 65
6) Return. This is because the color correction may be reset in the actual photographing, so that the photographer can adopt either one according to his / her preference at the time of previewing.

Here, the #REC "REC" subroutine will be described with reference to FIGS. First, R
In the EC mode, that is, whether or not recording (moving picture) is being performed is determined from the state of the flag RECF (# 720). If recording is not in progress, warning data is set (# 760) and this data is output to display a warning. (# 762). Then, it waits for the vertical synchronizing signal V _sync (# 764), and when this signal is input, it is determined whether or not the switch S _REC is off (# 766). If the switch S _REC is off,
If the process returns and is on, the process proceeds to # 762.

On the other hand, if the image is being recorded in # 720, it is judged whether or not the eyepiece flag SGRF is set (# 722). If it is not set, this flag is set (# 724) and # 68. Proceed to (Fig. 24). If set, the timer is reset and started (#
726), and then the exposure mode is set to the P mode (# 728). Subsequently, an operation for shooting preparation is performed (# 730), and it is determined whether the shooting mode is either silver salt still or electronic still (# 732, # 73).
4). If any of the shooting modes is selected, it is next determined whether or not the switch S ₂ is on (# 736). If it is on, shooting is performed in the set silver salt still shooting mode or electronic still shooting mode. (7), # 7
Proceed to 30. If neither the silver salt still image shooting mode nor the electronic still shooting mode is selected, or if the switch S ₂ is not on, it is determined whether the recording start switch S _REC has been turned from off to on (# 740), and from off to on. If so, it is determined from the state of the flag RECF whether or not recording is in progress (# 742). If recording is in progress, the flag RECF is reset (# 748), a recording stop signal is output (# 750), the timer is reset and started (# 754), and the process proceeds to # 730. On the other hand, if recording is not in progress, the flag RECF is set (# 744) and a recording start signal is output (# 746),
Furthermore, the timer is reset and started (# 754),
Go to # 730.

If the recording start switch S _REC is not turned from ON to OFF in # 740, it is determined from the state of the flag RECF whether or not recording is in progress (# 752). Still image preview (prior)
After the confirmation display is displayed (# 756), it is determined whether 5 minutes have passed without recording and no operation is performed (# 758), and if 5 minutes have passed, a return is made. To do. Until 5 minutes have elapsed, proceed to # 730. If recording is being performed in # 752, the timer is reset and started (# 754), and the flow proceeds to # 730.

Next, a description will be given of the control of the data interrupt when the data is sent from the microcomputer (μC3) 140 of the transceiver TX during the remote control.

This "data interrupt" subroutine is shown in FIG.
2 is used for the explanation. In this subroutine, when a signal indicating a data interrupt is input from the microcomputer (μC3) 140, subsequently, the microcomputer (μC3) 140 is sent from the transmitter / receiver RX during remote control, or the data being sent. Is input to the microcomputer (μC1) 1 (# 770). Next, it is determined whether or not the flag SREMF indicating the remote control mode is set (# 772). If the flag SREMF is not set, the remote control switch SREM is not turned on, and the process returns because it is not in the remote control mode. On the other hand, when the flag SREMF is set, it is returned to the reset state (# 774),
In step # 40 (FIG. 23), remote control is performed.

Next, FIGS. 53 to 63 show the sequence on the CCD / monitor / recording unit 10 side, which will be described with reference to the flowchart executed by the microcomputer (μC2) 100.

FIG. 53 is a flow chart showing an interrupt due to power-on or the like and an interrupt due to data input from the microcomputer (μC1) 1. That is, the power source is a microcomputer (μC
2) When supplied to 100, first, initial reset is performed for all flags, registers, etc. (S2). In this state, the display is performed by outputting the data from the frame memory 121, but since there is no moving image in the frame memory 121 when the power is turned on, no image is displayed. The CCD 43 is exposed, and an image is displayed after a time of several frames has passed. next,
The shutter speed TV of the CCD 43 is set to 1/60, a timing signal is generated from the timing signal generation circuit 101 according to the setting data, and the CCD 43 is controlled (S4). The interruption by the data input from the microcomputer (μC1) 1 takes place at S6, and the digital modulation circuit 116 is instructed to change the recording mode based on the vertical / horizontal camera attitude data from the microcomputer (μC1) 1 ( S6). Next, the display mode is determined according to the aspect ratio selected in each shooting mode, and is output to the microcomputer (μC21) 120 (S8).

Next, it is judged whether or not the switch S ₂ is turned on (S10), and if it is turned on, the "exposure control I" subroutine is executed (S12). On the other hand, if switch S ₂ is turned on, whether the switch S _PV is turned from off to on is discriminated (S14), if the on switch S _PV from OFF, PV control is performed (S16). If the switch S _PV does not become ON from OFF, whether flag PVF indicating the preview mode has been set or not (S18). If the flag PVF is set, color correction (manual correction, correction by film type) and exposure correction (by constant light or flash light) are performed (S20, S22), and the flag PVF must be set. For example, it is determined whether or not the switch S _DPI for displaying the still image is changed from off to on (S24). If the switch S _{D PI} is switched from off to on, the display control I for displaying a still image is executed (S26), and if the switch S _DPI is not switched from off to on, a flag DPI indicating this mode is set.
It is determined whether or not F is set (S2
8). If the flag DPIF is set, the display control II for changing the display is executed (S30), and if the flag DPIF is not set, the process directly proceeds to S32.

In S32, color correction is carried out, and then the above-mentioned marks and characters showing the photographing mode are displayed (S34). Then, the display data from the microcomputer (μC1) 1 for displaying the shutter speed and the photographing mode is output to the microcomputer (μC21) 120 which performs image processing, and further based on the input image data (R, G, B). Then, the aperture value in the moving image is calculated, and the exposure control is performed based on the calculated aperture value (S36). Further, WB control is performed by the WB control data obtained based on the input image data (R, G, B) (S38), and the process proceeds to S6.

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

[0140] Then, the shutter speed TV from the microcomputer (.mu.C1) 1 is converted into a real time T _CCD (S4
4). Here, the shutter speed TV is 6 or more (1 /
It is determined whether the shutter speed is 60 or less) (S46). If the value is 6 or more, the process directly proceeds to S56. On the other hand, if the shutter speed TV is less than 6,
The calculation of N _T = T _CCD / (1/60) is performed on the variable N _T , and N _T = N _AGC is set (S48, S50), and the exposure time is set to 1/60 which matches the field time (S52). ),
A flag MEXPF indicating that the exposure operation is repeated N _T times at 1/60 is set (S54).

In this embodiment, moving image / still photography (hereinafter, simply referred to as still photography includes both silver salt still photography and electronic still photography) is possible. One field is captured and recorded for each / 60. On the other hand, in still photography, particularly when the exposure mode is the P mode and the A mode, the exposure time is arbitrarily set according to the brightness. Has been decided. Further, when the exposure time is 1/60 or more, in moving image shooting, the image pickup is repeated every 1/60, and the _AGC 109 adjusts the gain based on the N _AGC so that the exposure is longer than 1/60. Deal with time, while in still photography, as described below,
Exposure times longer than 1/60 are addressed by summing multiple images obtained with every / 60 exposure.

At S54, an exposure OK signal is output to the microcomputer (μC1) 1 (S56). Microcomputer (μC1)
1 starts exposure control based on the photographing method set as described above. Next, wait for the exposure start signal from the microcomputer (μC1) 1 to be input (S58),
When this signal is input, a flag EXPF indicating that exposure is being performed is set (S60). continue,
After the exposure is completed and the flag EXPF is reset (S62), the process returns.

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

FIG. 55 shows the CCD / monitor / recording unit 10.
Below is a timing chart to explain the operation of
The outline of the operation will be described with reference to this figure.

First, the case of stationary light photography will be described. In the uppermost "operation" in the figure, when the release switch S ₂ is turned on, data indicating shooting is output from the microcomputer (μC1) 1 to the microcomputer (μC2) 100. The microcomputer (μC1) 1 performs a predetermined control for photographing, while the microcomputer (μC2) 100 receives the above data and performs a predetermined control, and then sends an “exposure OK” signal to the microcomputer (μC1). Return to 1. When the microcomputer (μC1) 1 receives the exposure OK signal, it waits for the vertical synchronization signal V _sync of the next cycle to be input, sends an “exposure start” signal to the microcomputer (μC2) 100, and controls the aperture. "Aperture control", and thereafter, the shutter 46 is driven "shutter exposure control". The microcomputer (μC2) 100 performs “CCD exposure control” that controls the exposure of the CCD 43 at the cycle of the vertical synchronizing signal V _sync of the next cycle.

Now, let us say that the image picked up at the first time in the exposure control for each vertical synchronizing signal V _sync is A1, and the second and subsequent times are A2, A3, ..., An. The signal of the first (first cycle) image A1 is the microcomputer (μC2) 100 after the exposure is completed.
The microcomputer (μC21) 120 performs predetermined image processing during the second period based on the signal from and is stored in the frame memories 121 and 122. The exposure control for the next image A2 is performed within the second period. here,
Assuming that the exposure time for proper exposure is 1/60 or more, the microcomputer (μC2) 100 outputs a control signal to the microcomputer (μC21) 120 in the third cycle, and the “adder O
N ”, the adder circuit 124 is turned on, the image A2 is added to the image A1 stored in the frame memory 121, and the image is stored in the frame memory 122. After that, this process is repeated until the exposure control ends (Nth cycle), the image captured by the CCD 43 is stored in the frame memory 121, and the frame memory 122 is sequentially added as described above. The image of ΣAi is stored. At this time,
The images stored in the frame memory 121 are sequentially displayed on the monitor 47 in the next cycle to obtain a moving image. Although the moving image at this time is displayed with insufficient exposure, when the switch S _DPI is operated, the microcomputer (μC2) 100 to the microcomputer (μC21) 12
A signal for instructing “display switching” is output to 0, whereby the ΣAi-processed still image is displayed in an appropriate exposure state. On the other hand, when the exposure time is 1/60 or less, the image Ai is stored in the frame memory 122 with a delay of one cycle. The image Bi in the next exposure control is similarly processed.

Next, memory control during flash photography will be described. The exposure time at this time is 1/6
It is 0 or less. The captured image A1 is stored in the frame memory 12
Stored in 2. Image O _N stored immediately before the frame memory 121 at this time are preserved, the image is displayed. This is to prevent noise from appearing to be mixed when only the image captured by flash photography for one cycle is included in the stationary light photography.

Next, referring to FIGS. 56 and 57, "V _sync
The “interrupt” will be described. When the vertical synchronizing signal V _sync is input, it is determined whether or not the flag EXENF indicating the end of exposure is set (S80). If not set, flag 1stF indicating the last exposure during exposure
Is set (S96).
If not set, a flag EXPF indicating that exposure is in progress
Is set (S10).
2). When the flag EXPF is set, the data of the exposure time T _CCD is output to the timing signal generation circuit 101, the control signal is output to the AGC 105, and its gain is set to 1 (not amplified) (S112, S11
4). WB is then uncontrolled and flag 1s
tF is set (S116, S118). continue,
The flag MEX indicates whether the control requires multiple exposure operations.
It is determined from the state of PF (S120), and if a plurality of exposure operations are required, it is determined whether or not the variable N _T is 1 (S122). If the variable N _T is 1, it means the last exposure, and the process proceeds to S128. On the other hand, if the variable N _T is not 1, the variable N _T is decremented by 1 (S124),
At this time, since it is not at least the last exposure, the flag 1stF is reset (S126) and the process proceeds to S128.

In S128, the variable N _E is incremented by 1, the gain of the AGC circuit 105 is set to N _AGC to optimize the exposure (S130), and then it is determined whether the variable N _E is 3 or not. (S132). Variable N _E
Is 3, the data for turning on the adder circuit 124 is set (S134), and then the frame memory 12
The data instructing the operation of adding the image stored in No. 2 and the latest image input from the microcomputer (μC21) 120 and storing in the frame memory 122 is set (S136). If the variable N _E is not 3, S as it is
Proceed to 138. In S138, the microcomputer (μC2) 10
The data set to 0 is the microcomputer (μC21) 12
0 (S138), then the microcomputer (μC1)
Based on the data from No. 1, it is determined whether the FL shooting in the preview shooting or the FL shooting in the electronic still shooting is performed (S140, S142). Which FL
If it is not photographing, shake detection is performed based on the G (green) component data input for each field, and shake correction control is performed based on this result (S148), and the process returns. On the other hand, in the case of FL shooting by preview shooting or electronic still shooting, measurement is performed for a predetermined time, for example, 8 msec, a flash light emission signal is output (S144, S146), and the process proceeds to S148.

If the exposure in the still photography mode is not being performed in S102, a signal for setting the exposure time to 1/60 is output to the timing signal generation circuit 101 (S104), and AG
A signal for setting the C circuit 105 to automatic and the AGC circuit 109 to gain 1 is output (S106, S1).
08), then the WB control signal is output, and S13
Go to 2.

When the last exposure operation is completed in S96 and the next field is reached (flag 1stF =
1) The memory control is performed, the flag EXENF indicating the end of the exposure control is set, and the process proceeds to S104.

Here, the "memory control" subroutine will be described with reference to FIG. First, the microcomputer (μC
1) It is determined based on the input data from 1 whether it is FL shooting (S160), and if it is FL shooting, updating of the stored contents of the frame memory 111 and the frame memory 121 used when recording a moving image is prohibited. , A control signal for prohibiting the input of image data is output (S162, S
164). In this way, by prohibiting the data update and storing and holding the image of the previous screen (corresponding to the image O _N shown in FIG. 55), only one field is included in the images of continuous continuous light photography. It is possible to prevent the noise-like display due to the inclusion of the FL captured image.

Next, the data for passing the image data as it is is set in the adder circuit 124 (S16).
6) It is determined whether or not it is FL shooting in the preview (S168). If the FL shooting is in the preview, the data for storing the image data is set in the frame memory 123 (S170). On the other hand, if the FL shooting is not in the preview, the image data is stored in the frame memory 122. Data is set (S17)
2). On the other hand, if it is not the FL shooting in S160, the process proceeds to S174 without performing such processing.

In S174, it is determined whether or not continuous shooting is performed,
If it is continuous shooting, data for instructing storage in the internal memory 129 is set for the time being (S176), and S178.
On the other hand, if it is not continuous shooting, the process directly proceeds to S178, and it is determined whether or not the electronic still shooting mode is set. If it is the electronic still photography mode, the data for instructing the data storage in the IC card 51 is set (S180) and the process returns. If not, the process returns as it is.

Returning to FIG. 56, the flag EXEN is obtained in S80.
If F is set, it is assumed that the exposure control has finished.
This flag EXENF is reset (S82), then data for turning off the adder circuit 124 is set (S84), and the input image data is stored as it is in the frame memory 121. Next, the flag 1stF, the flag EXPF, and the flag MEXPF are reset (S86 to S90) to enable continuous recording of the moving image, and further, the frame memory 12
Data for instructing restart of data input to 1 is set (S92, S94). These S92, S94
By the processing of (1), the prohibition state of each data input at the time of FL photographing is released.

Next, "PV control", "exposure correction" in the preview mode, and "color correction" in the preview mode shown in FIG. 53 will be described with reference to FIGS. 59 to 61. In FIG. 59, first, it is determined whether or not it is the second continuous shooting in the preview mode, that is, whether or not FL flash shooting is performed (S1).
90). If it is not the second time, it is judged from the state of the flag PVF whether it is in preview (S192). If it is in preview, this flag PVF is reset (S1).
98), exits the preview mode and returns. On the other hand, if the preview is not being performed, the flag PVF is set so that the preview is being performed (S194), the exposure control is performed (S196), and the process returns. When the second continuous shooting in the preview mode is performed in S190, the exposure control is performed (S196) and the process returns.

In FIG. 60, first, the microcomputer (μC1) 1
It is determined whether or not the correction amount of the FL light from is changed with respect to the previous input value, and if it is changed, the change amount ΔEV _FLPV is obtained and set (S210, S21).
2) Then, it is determined whether or not the correction amount in the constant light has changed with respect to the previous input value, and if it has changed, the change amount ΔEV _AMBPV is obtained and set (S2
14, S216), and returns. In addition, the correction with FL light is {(memory 122)-(memory 121)} × (Δ
EV _FLPV ) + (memory 123), and the obtained data is stored in the memory 122. In addition, the correction with constant light is (memory 122) × (ΔEV _AMBPV ) + {(memory 123)
-(Memory 122)}, and outputs the data for storing the obtained data in the memory 122.

In FIG. 61, first, the correction data ΔB, ΔR
Is set to a value 0, and the correction amount Δ to be corrected based on the color correction data ΔB _C , ΔB ₂ input from the camera body 20 side.
R _C and ΔR ₂ are obtained (S220). Next, it is determined whether the film type is daylight, tungsten, or black and white (S222), and if the loaded film is the tungsten type, the color correction amount Δ corresponding to this is determined.
Let B ₁ and ΔR ₁ be ΔB _t and ΔR _t (S224, S22
6) If it is a daylight type, ΔB _d and ΔR _d are set (S234, S236). Then, the overall color correction amount Δ
Where B and ΔR are ΔB = ΔB ₁ + ΔB ₂ , ΔR = ΔR ₁ + ΔR ₂
The control signal i is created according to the correction amounts ΔB and ΔR thus obtained (S228 to S232), and the process returns. If the film type is black and white (W.
B), create control data for deleting the color information (S238), and return.

Next, "display control I" and "display control II" will be described with reference to FIGS. In FIG. 62, first,
It is determined based on the input data from the microcomputer (μC1) 1 whether or not recording is in progress (S250). If recording is in progress, the process directly returns. If not recording, the process proceeds to S252. In step S252, a flag DPIF indicating that a still image is being displayed is displayed.
Is set, and if it is set, this flag DPIF is reset, that is, the still image display mode is exited (S254), and then the input destination of the data instructing the display is set from the frame memory 122 to the frame. Data for switching to the memory 121 is set (S256), and the process returns. If the flag DPIF is not set in S252, this flag D
The PIF is set (S258), then the data for switching the input destination of the data instructing the display from the frame memory 121 to the frame memory 122 is set (S260), and the process returns.

In FIG. 63, first, it is determined whether or not this routine showing the change of the still image is passed once by the flag DP1.
It is determined from the state of stF (S270), and when it has not passed yet, it is determined whether or not a change operation, that is, whether the switch DP _UP is turned on from off (S27).
2). If the switch DP _UP has not been turned on from off, the routine proceeds to S278, where a flag DP1st indicating that this routine has been passed is set and the routine returns. If the switch DP _UP is turned on from off, the currently displayed read address of the internal memory 129 is increased and addressing is performed (S274). Then, the display switching data for transferring the image stored in the designated address of the internal memory 129 to the frame memory 122 is set (S276), and the process proceeds to S78.
The frame memory 122 outputs the image data while inputting the image data from the internal memory 129,
indicate. When the flag DP1stF is set in S260, the flag DP1stF is reset (S280) and the process returns.

Since the control operation of the microcomputer (μC21) 120 has been described in relation to the microcomputer (μC2) 100, its description is omitted. Microcomputer (μ
In C21) 120, based on the input data from the microcomputer (μC2) 100, the above-described insertion of the character into the monitor 47, addition / subtraction of image data, color conversion, control of the frame memories 121 and 122, display switching control, Control of the adder circuit 124, control of the switch 125, storage control of the IC card 51, control of the internal memory 129, and display control according to the selection of the aspect ratio in the silver salt still shooting mode, the electronic still shooting mode, and the moving image shooting mode. And so on.

Next, referring to FIGS. 64A and 64B, the microcomputer (μC3) 140 of the transceiver TX and the transceiver RX will be described.
The control of the microcomputer (μC4) 150 will be described.
(A) is a control flow of the microcomputer (μC3) 140,
(B) shows a control flow of the microcomputer (μC4) 150.

The microcomputer (μC3) 140 uses the switch S
_{When the REM} turns from off to on, an interrupt “S _REM INT” is executed, and when the vertical synchronization signal V _sync from the timing control is input (# R2), control data is wirelessly transmitted to the transmitter / receiver R.
It is output to X, and then one screen of image data is output (# R4, # R6). Next, switch data is wirelessly input from the transceiver RX, and this switch data is output to the microcomputer (μC1) 1 (# R8, # R10),

0- # R22). Next, the microcomputer (μC4) 150 detects the states of various switches, stores the detection results in the built-in RAM, and wirelessly transmits and receives these switch data.
Output to X and shift to the interrupt standby state (# R24-
# R28). As described above, the transceiver RX does not perform calculations by operating the switches, outputs only switch data to the transceiver TX, and controls the transmitter / receiver TX according to the state of the switch.

In the above embodiment, CC is used as the image sensor.
Since a D (solid-state image sensor) type is used,
When the exposure time is longer than 1/60 in still shooting mode, the image obtained every 1/60 is read and added to the previous image to obtain an appropriate exposure, and the image obtained every 1/60 Although the gain is digitally adjusted to obtain an appropriate exposure, a nondestructive image sensor shown in FIG. 65 may be used instead. This type of sensor can read data every 1/60 while accumulating accumulated charges due to light. Therefore, if the read data is treated as an image and exposure is continued, a still image with proper exposure can be obtained. Is obtained.

[0167]

[Equation 1]

The image sensor 300 comprises photoelectric conversion cells in a matrix, and the photoelectric conversion cells are arranged and formed on the n ₊ silicon substrate 301. Each cell has SiO ₂ , S
Element isolation region 30 made of i ₃ N ₄ or polysilicon
2 electrically insulates cells adjacent to each other. Each cell has the following structure. An n ₋ region 303 having a low impurity concentration is formed on the n ₊ silicon substrate 301 by an epitaxial technique or the like, and a p region 304 is formed by doping p type impurities on the n ₋ region 303.
An n ₊ region 305 is formed in the p region 304 by an impurity diffusion technique or an ion implantation technique. P region 304 and n ₊ region 305 are the base and emitter of the bipolar transistor, respectively. An oxide film 306 is formed on the n ₋ region 303 in which each region is formed in this way, and a capacitor electrode 307 having a predetermined area is formed on the oxide film 306. Capacitor electrode 307
Opposes the p region 304 across the oxide film 306 and controls the potential of the p region 304 in a floating state by applying a pulse voltage to the capacitor electrode 307. In addition, the emitter electrode 308 connected to the n ₊ region 305 and the substrate 301
An n ₊ region 311 having a high impurity concentration and a collector electrode 312 for applying a potential to the collector of the bipolar transistor are formed on the back surface of the bipolar transistor.

Next, the basic operation will be described. First, it is assumed that the p region 304, which is the base of the bipolar transistor, is in the initial state of negative potential. Light 313 enters from the p region 304 side, holes of the electron-hole pairs generated by the incident light are accumulated in the p region 304, and the accumulated holes cause the potential of the p region 304 to be in the positive direction. Rises to (accumulation operation). Then, a positive voltage pulse for reading is applied to the capacitor electrode 307, and a reading signal corresponding to the change in the base potential during the accumulation operation is output from the floating emitter electrode 308 (reading operation). However, since the accumulated charge amount of the p region 304 which is the base hardly decreases, the read operation can be repeated. To remove the holes accumulated in the p region 304, the emitter electrode 308 is grounded and a positive voltage refresh pulse is applied to the capacitor electrode 307. By applying this pulse, the p region 304 is biased in the forward direction with respect to the n ₊ region 305, and the accumulated holes are removed. And
When the refresh pulse falls, the p region 30
4 returns to the initial state of negative potential (refresh operation). Thereafter, the operations of accumulating, reading and refreshing are similarly repeated.

Furthermore, as another method of the exposure operation, the exposure is cut off at 1/60, and the AGC is performed in the same manner as in a normal moving image.
A gain of 1 may be set in the circuit 105 (the AGC circuit 109 is not necessary), and it may be determined by this gain whether or not the exposure is within the proper range. Within the range of proper exposure, both moving images and still images are appropriate for exposure. On the other hand, in this case, a still image shot on a silver halide film has a different degree of image shake due to a difference in shutter speed. Therefore, when the shutter speed becomes slow enough to cause the problem of image blur, an alarm display may be provided to inform the photographer of the fact.

[0171]

As described above, according to the present invention,
Since the set aspect ratio is recorded on the photosensitive medium and the display mode of the monitor is changed according to the set aspect ratio, it is possible to appropriately change the aspect ratio when shooting on the photosensitive medium. Confirmation becomes easy. Further, since the set aspect ratio is recorded on the photosensitive medium, an appropriate printing operation during development is possible and easy.
