DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for capturing, recording, and reproducing still images and moving images, and a method for controlling the image processing apparatus.

[0002]

2. Description of the Related Art Conventionally, an image processing apparatus such as an electronic camera for recording and reproducing a still image or a moving image using a memory card having a solid-state memory element as a recording medium is already on the market.
An electronic camera equipped with an electronic finder such as a color liquid crystal panel is also sold.

According to these electronic cameras, it is possible for the user of the electronic camera to continuously determine the composition by continuously displaying images before shooting, and to reproduce and display the shot images for confirmation. .

[0004] In particular, the function of reproducing a photographed image immediately after photographing is highly convenient and is a useful function for a user of an electronic camera.

[0005]

In such an image processing apparatus such as a conventional electronic camera, since the writing speed to a recording medium is relatively slow, the photographed image data is temporarily stored in a buffer memory. Generally, a method of reading the data from the buffer memory and recording the data on a recording medium is generally adopted.

In this case, if continuous photographing is performed, photographed image data is stored in the buffer memory one after another. However, as described above, since the writing speed to the recording medium is relatively slow, continuous photographing is performed. Immediately after that, the image data written on the recording medium cannot be immediately reproduced and displayed.

[0007] In particular, when the buffer memory has a large capacity, the difference between the storage speed in the buffer memory and the writing speed in the recording medium becomes remarkable. There was a problem that it was inconvenient to confirm.

On the other hand, when the reproduction switch is pressed, the image data temporarily stored in the buffer memory is used,
By performing playback display immediately after shooting, it is possible to check the image immediately after the continuous shooting, but in this case, since the image data has not yet been written to the recording medium, the shot image is played back. If the recording medium is removed for the purpose of confirmation, the image data becomes unrecorded or the image data is destroyed.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an image processing apparatus, a method of controlling the same, and a storage medium, which prevent writing omission to a recording medium. It is.

The image processing apparatus 10 will be described with reference to FIGS.
The operation of 0 will be described.

When the power is turned on such as when the battery is replaced, the system control circuit 50 initializes flags, control variables, and the like (S10).
l), the image display of the image display unit 28 is initially set to an OFF state (S102).

The system control circuit 50 includes the power switch 6
6 is set, and the power switch 66 is turned off.
(S103), the display of each display unit is changed to the end state, and necessary parameters including flags, control variables, etc., setting values, and setting modes are set in the nonvolatile memory 56.
After performing predetermined termination processing such as shutting off unnecessary power of each unit of the image processing apparatus 100 including the image display unit 28 by the power supply control unit 80 (S104), the process returns to S103.

If the power switch 66 is set to power ON (S103), the system control circuit 50 determines the set position of the mode dial 60, and
If 0 has been set to the shooting mode (S105),
Proceed to S107.

If the mode dial 60 has been set to another mode (S105), the system control circuit 5
0 executes a process according to the selected mode (S10
6) When the processing is completed, the process returns to S103.

The system control circuit 50 includes the power control means 8
In step S107, it is determined whether the remaining capacity of the power source 86 composed of a battery or the like or the operating condition has a problem in the operation of the image processing apparatus 100 (S107). After a predetermined warning is displayed by voice (S109), the process returns to S103.

If there is no problem with the power supply 86 (S10
7), the system control circuit 50 determines whether the recording medium 200 or 210 is mounted,
Acquisition of management information of the image data recorded in 0 or 210, and whether or not the operation state of the recording medium 200 or 210 has a problem in the operation of the image processing apparatus 100, particularly, in the operation of recording and reproducing image data on the recording medium. Is determined (S108), and if there is a problem, a predetermined warning is displayed by image or sound using the display unit 54 (S10).
9) Return to S103.

It is determined whether or not the recording medium 200 or 210 is mounted, management information of the image data recorded on the recording medium 200 or 210 is obtained, and the operation state of the recording medium 200 or 210 is determined by the image processing apparatus 100.
(S10) as a result of determining whether or not there is a problem in the operation of S10, particularly in the operation of recording and reproducing image data on the recording medium.
8) If there is no problem, proceed to S110.

In step S108, the system control circuit 50 also obtains the last record number Nmax of the image data recorded on the recording medium 200 or 210.

[0139] The final recording number Nmax is stored in the recording medium 200.
Alternatively, the data is read out from the connector 210 or 96 via the connector 92 or 96 and the interface 90 or 94 and stored in the internal memory of the system control circuit 50 or the memory 52.

The system control circuit 50 uses the display unit 54 to display various setting states of the image processing apparatus 100 using images and sounds (S110). When the image display of the image display unit 28 is ON, the various setting states of the image processing apparatus 100 are displayed by the image display unit 28 using images and sounds.

The system control circuit 50 checks the setting of the quick review ON / OFF switch 68 for setting the quick review function for automatically reproducing the image data immediately after the photographing (S111), and sets the quick review ON. If so, the quick review flag is set (S112), and the process proceeds to S114. If the quick review has been set to OFF, the quick review flag is released (S113), and the process proceeds to S114.

The state of the quick review flag is as follows.
It is stored in the internal memory of the system control circuit 50 or the memory 52.

If a series of photographing and recording sequences has already been executed and the recording of the photographed image data on the recording medium 200 or 210 is in the middle of being performed, new image data is recorded on the recording medium 200 or 210. When the recording is completed (S114), the system control circuit 50 updates the last recording number Nmax (S115), and proceeds to S121.
Proceed to.

If new image data has not been recorded on the recording medium 200 or 210, or if image data has not been recorded yet (S114), the process proceeds to S121.

Accordingly, even when image data is being recorded on the recording medium 200 or 210 sequentially after continuous shooting, each time image data is newly recorded,
The last record number Nmax can be updated.

The system control circuit 50 controls the reproduction switch 6
It is determined whether 6 is set to ON or OFF (S121).

If the reproduction switch 66 has been set to OFF (S121), the process proceeds to S127.

As described above, when the reproduction switch 66 is OFF, it means that a series of operations in the photographing mode is being executed, or a state in which a series of operations in the reproduction mode has already been executed. It is determined that it is one of them, and the process proceeds to S127 without performing the processing of S122 and thereafter. In addition,
Whether or not the reproduction mode has already been executed can be determined using a reproduction mode flag, as described later.

If the reproduction switch 66 has been set to ON (S121), the system control circuit 50 determines the state of the reproduction mode flag (S122).

If the reproduction mode flag has been set, that is, if it is determined that the reproduction mode has already been executed (S122), the system control circuit 50 determines whether or not the last record number Nmax has been updated. It is determined (S128), and if updated, the process proceeds to S126,
If not, the process proceeds to S127.

As described above, even if the reproduction switch 66 is ON, if the reproduction mode flag has already been set, it is determined that a series of operations in the reproduction mode has already been executed. The process proceeds to S128 without performing the processing from S123 to S125.

If the reproduction mode flag has been released, that is, if it is determined that the reproduction mode is to be newly executed (S122), the system control circuit 50
Sets a reproduction mode flag (S123), and proceeds to S124.

The state of the reproduction mode flag is stored in the internal memory of the system control circuit 50 or the memory 52.

As described above, if the reproduction mode flag has been released when the reproduction switch 66 is ON, the photographing mode is currently being executed.
Since is not pressed, it can be determined that the shooting operation is not being performed. Then, a series of operations in the photographing mode is temporarily stopped, and the recording medium 200 or 2
A series of operations in the reproduction mode for reproducing the image data recorded in the recording device 10 is started.

Subsequently, the system control circuit 50 performs predetermined settings necessary for executing the reproduction mode (S1).
24), the last record number Nmax read in S108 and stored in the internal memory of the system control circuit 50 or in the memory 52 is read (S125), and the process proceeds to S126.

Then, the system control circuit 50 sets the reproduction image number N to N = Nmax (S126), and proceeds to S1.
Proceed to 27.

The reproduced image number N is stored in the internal memory of the system control circuit 50 or in the memory 52.

As a result, immediately after the reproduction mode is executed, the image data finally recorded on the recording medium 200 or 210 can be read out and displayed without selecting an image using the image selection key. It is convenient for users.

If the last recording number Nmax has been updated, a new reproduced image number N is set to N = Nmax.
By setting Nmax, even if a playback switch is pressed during the sequential recording of image data on the recording medium 200 or 210 after continuous shooting, each time new image data is recorded, the image is sequentially reproduced. It is possible to update the image number N and switch the reproduction display image.

If the reproduction mode flag has been set (S127), the system control circuit 50 proceeds to S181.

This is a state in which a series of operations in the photographing mode is temporarily suspended, and a series of operations in the reproducing mode for reproducing the image data photographed and recorded on the recording medium 200 or 210 is started. Or a state in which a series of operations in the reproduction mode has already been executed.

If the reproduction mode flag has been released (S127), the process proceeds to S141.

This corresponds to a state where a series of operations in the photographing mode is being executed.

If the shutter switch SW1 has not been pressed (S141), the flow returns to S103.

If the shutter switch SW1 is pressed (S141), the system control circuit 50 performs a distance measurement process to focus the photographing lens 310 on a subject, and performs a photometry process to determine an aperture value and a shutter time. Then, a distance measurement / photometry process is performed (S142), and the process proceeds to S143. In the photometry processing, the flash setting is also performed if necessary.

The details of the distance measurement / photometry processing S142 are shown in FIG.
Will be described later.

If the shutter switch SW2 has not been pressed (S143), the system control circuit 50 determines whether the recording of new image data on the recording medium 200 or 210 has been completed (S144).

When the recording of new image data on the recording medium 200 or 210 is completed (S144), the system control circuit 50 updates the last recording number Nmax (S144).
145), and return to S141.

If new image data has not been recorded on the recording medium 200 or 210, or if image data has not been recorded yet (S144), the flow returns to S141.

Thus, even if the image data is being recorded on the recording medium 200 or 210 sequentially after the continuous shooting, every time the image data is newly recorded,
The last record number Nmax can be updated.

If the shutter switch SW2 is pressed (S143), the system control circuit 50 determines the status of the quick review flag stored in the internal memory of the system control circuit 50 or the memory 52 (S146), and Is set, the display of the image display unit 28 is set to the OFF state (S147), and S
Proceed to 148.

If the quick review flag has been released (S146), the flow advances to S148.

The system control circuit 50 determines whether or not there is an image storage buffer area capable of storing the captured image data in the memory 30 (S148), and stores new image data in the image storage buffer area of the memory 30. If there is no available area, a predetermined warning display is performed by image or sound using the display unit 54 (S149), and the process returns to S103.

For example, immediately after the maximum number of continuous shots that can be stored in the image storage buffer area of the memory 30 has been performed,
Read from the memory 30 and read the storage medium 200 or 210
In this case, the first image to be written to the storage medium 200 or 210 is not yet recorded in the recording medium 200 or 210, and one empty area cannot be secured in the image storage buffer area of the memory 30. This is an example.

When the photographed image data is compressed and stored in the image storage buffer area of the memory 30, the amount of compressed image data differs according to the setting of the compression mode. The area that can be stored is memory 3.
In step S148, it is determined whether or not the area is in the image storage buffer area 0.
Will be determined.

If there is an image storage buffer area in the memory 30 capable of storing photographed image data (S148),
The system control circuit 50 controls the memory 30 via the image sensor 12, the A / D converter 16, the image processing circuit 20, the memory control circuit 22, or directly from the A / D converter via the memory control circuit 22. Exposure processing for writing image data captured in an area, and development processing for reading image data written in a predetermined area of the memory 30 and performing various processing using the memory control circuit 22 and, if necessary, the image processing circuit 20 (S15)
0).

The details of the photographing process S150 will be described later with reference to FIG.

When the photographing process S150 is completed, the system control circuit 50 reads out the photographed image data written in a predetermined area of the memory 30, and uses the memory control circuit 22 and the image processing circuit 20 as necessary. Various image processing is performed, and a compression process for performing an image compression process according to a mode set using the compression / decompression circuit 32 is performed as necessary (S151).

The details of this compression processing S151 will be described later with reference to FIG.

After the completion of the compression processing S151, the system control circuit 50 writes the image data having undergone a series of processing by photographing in a free image portion of the image storage buffer area of the memory 30 (S152). Accordingly, the image storage number Mm for the image storage buffer area of the memory 30
ax is updated (S153).

With the execution of photographing, the system control circuit 50
Reads the image data stored in the image storage buffer area of the memory 30 and
A recording medium 200 or 21 such as a memory card or a compact flash card is connected via the connector 92 or 96.
A recording process for writing to 0 is started (S154).

This recording start process is performed every time image data that has been photographed and a series of processes has been completed is newly written in a free image portion of the image storage buffer area of the memory 30.
The operation is performed on the image data.

While the image data is being written to the recording medium 200 or 210, the display unit 54 displays, for example, L
A recording medium writing operation display such as blinking of the ED is performed.

When the recording of new image data on the recording medium 200 or 210 is completed (S155), the system control circuit 50 updates the last recording number Nmax (S155).
156), and proceed to S161.

If the recording of new image data on the recording medium 200 or 210 has not been performed, or the recording of the image data has not been completed even if the recording has been performed (S155), the flow proceeds to S161.

Thus, even if the image data is being recorded on the recording medium 200 or 210 sequentially after the continuous photographing, every time the image data is newly recorded,
The last record number Nmax can be updated.

The system control circuit 50 determines the state of the continuous shooting flag stored in the internal memory of the system control circuit 50 or the memory 52 (S161). If the continuous shooting flag is not set, the process proceeds to S163.

If the continuous shooting flag is set (S1
61), the system control circuit 50 controls the shutter switch S
It is determined whether W2 has been pressed (S162).

If the shutter switch SW2 is in the pressed state (S162), the flow returns to S146 to continuously perform photographing, and the next photographing is performed.

If the shutter switch SW2 has been released (S162), the system control circuit 50 determines the state of the quick review flag stored in the internal memory of the system control circuit 50 or the memory 52 (S162).
184) If the quick review flag has been released, the process proceeds to S166.

If the quick review flag has been set (S163), the system control circuit 50 sets the review image number M to M = Mmax (S164), performs photographing and performs various processes, and then stores the review image number M in the memory 30. A quick review process of reading out the image data written in the image storage buffer area and displaying a review on the image display unit 28 is performed (S165).

The details of the quick review processing S165 will be described later with reference to FIG.

As described above, according to the present embodiment, when performing the quick review display, the image data last written in the image storage buffer area of the memory 30 can be read and displayed. The image data taken from the image storage buffer area is read out and recorded on the recording medium 200 or 210.
Alternatively, it is possible to promptly display a captured image without waiting for a series of processing of reading image data from 210. In particular, a quick review display can be performed without waiting for a relatively long recording process on the recording medium 200 or 210, so that a captured image can be quickly confirmed.

If the shutter switch SW1 has been pressed when S165 is completed (S16
6), the system control circuit 50 determines the state of the continuous shooting flag stored in the internal memory of the system control circuit 50 or the memory 52 (S167). If the continuous shooting flag is set, continuous shooting is performed. The process returns to S143 in preparation for execution.

If the continuous shooting flag is not set (S
167) The current process is repeated until the shutter switch SW1 is released (S166).

If the shutter switch SW1 has not been pressed (S166), the system control circuit 50 determines the state of the quick review flag stored in the internal memory of the system control circuit 50 or the memory 52 (S168). If the quick review flag has been released, the process returns to S103.

If the quick review flag has been set (S168), the system control circuit 50 executes a review image selection process (S169).

The details of this review image selection processing S169 will be described later with reference to FIG.

As a result of executing the review image selection processing S169, the system control circuit 50 determines whether or not the selection of a review image has been executed (S170). If not, the process proceeds to S172.

If the review image is selected (S170), the image data written to the image storage buffer area of the memory 30 after photographing and performing various processes on the selected new review image Is read and the image display unit 28 performs a quick review process of displaying a review (S171).

This quick review processing S171 is
This processing is equivalent to 165, and details thereof will be described later with reference to FIG.

Until the predetermined minimum review time has elapsed (S172), the flow returns to S169 to perform a series of processing.

As described above, by continuing the quick review display on the image display unit 28 for a predetermined time, it is possible to surely confirm the photographed image and to continue the quick review display for an unnecessarily long time. Thus, it is possible to prevent the next shooting opportunity from being lost.

The minimum review time may be a fixed value, may be arbitrarily set by the user, or may be arbitrarily set or selected by the user within a predetermined range. , May be set by any method.

If the minimum review time has elapsed (S172), the system control circuit 50 causes the image display unit 2
The display of No. 8 is set to the OFF state (S173), a series of photographing operations is completed, and the process returns to S103.

The system control circuit 50 reads the reproduced image number N stored in the internal memory or the memory 52 of the system control circuit 50 and selects reproduced image data corresponding to the reproduced image number N (S181). It is determined whether the image data to be stored exists in the memory 30 (S182).

If the image data corresponding to the reproduced image data exists in the image storage buffer area in the memory 30,
The system control circuit 50 allocates the image data existing in the image storage buffer area in the memory 30 as having been read from the storage medium (S183). In this case, since the read operation from the storage medium 200 or 210 is unnecessary, the reproduction / display operation can be started at a high speed.

If the image data corresponding to the reproduced image data does not exist in the memory 30 (S182), the system control circuit 50 transmits the data from the recording medium 200 or 210 such as a memory card or a compact flash card to the connector 92 or 96, Via the interface 90 or 94, image data corresponding to the reproduced image number N is read,
A recording medium read process stored in the image storage buffer area of the memory 30 is executed (S184).

[0209] The system control circuit 50 performs image decompression processing on the read image data by the image compression / decompression circuit 32.
(S185), and the image subjected to the image expansion processing is stored in a predetermined area in the memory 30.

The details of this decompression processing S185 will be described later with reference to FIG.

The system control circuit 50 executes display image processing of reading image data stored by performing image expansion processing from a predetermined area of the memory 30 and transferring the image data to the image display memory 24 via the memory control circuit 22 ( S18

If the shutter switch SW1 is released while displaying the reproduced image (S18).
9), the system control circuit 50 executes a reproduction image selection process (S190).

The details of the reproduced image selection processing S190 will be described later with reference to FIG.

When the reproduction image selection processing S190 has been completed, the flow returns to S103.

If the shutter switch SW1 is pressed while displaying the reproduced image (S18).
9) The system control circuit 50
The state of the image display flag stored in the internal memory or the memory 52 is determined (S191). If the image display flag is set (S191), the process proceeds to S193.

If the image display flag has been cleared (S191), the image display of the image display unit 28 is set to the OFF state (S192), and the flow advances to S193.

[0219] The system control circuit 50 clears the reproduction mode flag (S193), performs various settings necessary for executing the photographing mode (S194), and returns to S103.

Thus, when the image is being reproduced, S
When W1 is pressed, the reproduction mode flag is released, the predetermined setting required for executing the photographing mode is performed, and the image processing apparatus 100 can be promptly photographed.

FIG. 7 is a detailed flowchart of the distance measurement / photometry processing in S142 of FIG.

After performing the charge clear operation of the image pickup device 14, the system control circuit 50 starts the charge accumulation (dark image accumulation) of the image pickup device 14 with the shutter 12 closed.

After a predetermined time has elapsed, the system control circuit 50 reads out the charge signal from the image sensor 14 and
Through the A / D converter 16, the image processing circuit 20, the memory control circuit 22, or directly from the A / D converter 16 via the memory control circuit 22, image data (dark image data) ) Is written (S201).

By performing development processing using the dark captured data, the photographed image data is corrected with respect to image quality deterioration such as dark current noise generated by the image sensor 14 and pixel defects due to scratches inherent to the image sensor 14. Can be done.

The dark image data is held in a predetermined area of the memory 30 until a new distance measurement / photometry process is performed or the power of the image processing apparatus 100 is turned off. Processing is performed, where

As described above, according to the first embodiment of the present invention, in the shooting operation state immediately after the continuous shooting,
The last image data stored in the image storage buffer area in the memory 30 is read out and displayed on the image display unit 28 for quick review display. On the other hand, in the playback operation state immediately after continuous shooting, the image data recorded on the recording medium 200 or 210 is read. A series of continuously shot image data can be sequentially reproduced and displayed from the image data of the frame whose recording has been completed most recently.

Thus, in the photographing operation state immediately after the continuous photographing, even if the photographed image data has not been recorded on the recording medium, the display of the last photographed image data can be promptly performed immediately after the photographing. On the other hand, in the reproducing operation state immediately after the continuous shooting, it is possible to always use the image data already recorded on the recording medium and to switch to new image data every time recording is completed to reproduce and display the image data.

In particular, in the first embodiment, if the image data read from the recording medium and reproduced and displayed in the image storage buffer area of the memory 30 in the reproduction operation state immediately after the continuous shooting, the image data is By using the display, the reproduction and display of the image data can be started more quickly.

After performing predetermined termination processing such as shutting off unnecessary power of each unit of the image processing apparatus 100 including the image display unit 28 by the power supply control unit 80 (S1104), the process proceeds to S110.
Return to 3.

If the power switch 66 is set to power ON (S1103), the system control circuit 50 determines the set position of the mode dial 60, and if the mode dial 60 is set to the photographing mode (S110).
5) The process proceeds to S1107.

If the mode dial 60 has been set to another mode (S1105), the system control circuit 50 executes a process according to the selected mode (S11).
06) When the process is completed, the process returns to S1103.

The system control circuit 50 includes the power control means 8
In step S1107, it is determined whether the remaining capacity or the operating state of the power supply 86 composed of a battery or the like has a problem in the operation of the image processing apparatus 100 (S1107).
After performing a predetermined warning display by image or sound using (S1109), the process returns to S1103.

If there is no problem with the power supply 86 (S110)

09), returning to S1103.

It is determined whether or not the recording medium 200 or 210 is mounted, management information of the image data recorded on the recording medium 200 or 210 is obtained, and the operation state of the recording medium 200 or 210 is determined by the image processing apparatus 100.
(S110) as a result of determining whether or not there is a problem in the operation of step S110, particularly the operation of recording and reproducing image data on the recording medium.
8) If there is no problem, proceed to S1110.

In step S1108, the system control circuit 50 also obtains the last record number Nmax of the image data recorded on the recording medium 200 or 210.

[0300] The final recording number Nmax corresponds to the recording medium 200.
Alternatively, the data is read out from the connector 210 or 96 via the connector 92 or 96 and the interface 90 or 94 and stored in the internal memory of the system control circuit 50 or the memory 52.

The system control circuit 50 uses the display unit 54 to display various setting states of the image processing apparatus 100 using images and sounds (S1110). When the image display of the image display unit 28 is ON, the various setting states of the image processing apparatus 100 are displayed by the image display unit 28 using images and sounds.

The system control circuit 50 checks the setting state of the quick review ON / OFF switch 68 for setting the quick review function for automatically reproducing the image data immediately after the photographing (S1111), and turns on the quick review.
If it has been set to, a quick review flag is set (S1112), and the process proceeds to S1114. If the quick review has been set to OFF, the quick review flag is released (S1113), and the process proceeds to S1114.

The state of the quick review flag is
It is stored in the internal memory of the system control circuit 50 or the memory 52.

If a series of photographing and recording sequences have already been executed and recording of photographed image data on the recording medium 200 or 210 is in progress, new image data is recorded on the recording medium 200 or 210. If the recording has been completed (S1114), the system control circuit 50 updates the last recording number Nmax (S1115) and returns to S1.
Go to 121.

If new image data has not been recorded on the recording medium 200 or 210, or if recording has not been completed yet (S1114), the flow advances to step S1121.

Thus, even when image data is being recorded on the recording medium 200 or 210 sequentially after continuous shooting, each time image data is newly recorded,
The last record number Nmax can be updated.

The system control circuit 50 controls the reproduction switch 6
It is determined whether 6 is set to ON or OFF (S1121).

If the reproduction switch 66 has been set to OFF (S1121), the flow advances to S1127. As described above, when the reproduction switch 66 is OFF, either a state in which a series of operations in the shooting mode is being performed or a state in which a series of operations in the reproduction mode have already been performed. If it is determined that there is, the processing proceeds to S1127 without performing the processing of S1122 and thereafter. Note that whether or not the playback mode has already been executed is as described above.
The determination can be made using the reproduction mode flag.

If the reproduction switch 66 has been set to ON (S1121), the system control circuit 50 determines the state of the reproduction mode flag (S1122).

If the reproduction mode flag has been set, that is, if it is determined that the reproduction mode has already been executed (S1122), the flow advances to S1127.

As described above, even if the reproduction switch 66 is ON, if the reproduction mode flag has already been set, it is determined that a series of operations in the reproduction mode has already been executed. The process proceeds from S1123 to S1127 without performing the process from S1125.

If the reproduction mode flag has been released, that is, if it is determined that the reproduction mode is to be newly executed (S1122), the system control circuit 5
0 sets the reproduction mode flag (S1123), and S11
Proceed to 24.

Note that the state of the reproduction mode flag is stored in the internal memory of the system control circuit 50 or the memory 52.

As described above, if the reproduction mode flag has been released when the reproduction switch 66 is turned on, the photographing mode is currently being executed.
Since is not pressed, it can be determined that the shooting operation is not being performed. Then, a series of operations in the photographing mode is temporarily stopped, and the recording medium 200 or 2
A series of operations in the reproduction mode for reproducing the image data recorded in the recording device 10 is started.

Subsequently, the system control circuit 50 makes predetermined settings necessary for executing the reproduction mode (S1).
124), the last record number Nmax read out in S108 and stored in the internal memory of the system control circuit 50 or in the memory 52 is read out (S1125), and S11
Proceed to 26.

In S1126, the system control circuit 50 checks the internal memory or the memory 5 of the system control circuit 50.
2 is read out, the reproduction image number N is set to N = Nnew (S1126), and the process proceeds to S1127.

Nnew indicates that the photographed image data is stored in the recording medium 200 or 210 when single or continuous shooting is started.
Is stored in the internal memory of the system control circuit 50 or the memory 52 in step S1126 as described above.

By using this Nnew, when a reproducing operation is performed immediately after photographing, it is possible to start reproducing and displaying from the first photographed image data in the continuously photographed images photographed immediately before.

[0319] The reproduced image number N is stored in the internal memory of the system control circuit 50 or the memory 52.

Thus, immediately after executing the reproduction mode, it is possible to read and display the last image data recorded on the recording medium 200 or 210 without using the image selection key to select an image. It is convenient for users.

If the last recording number Nmax has been updated, a new reproduced image number N is set to N = Nmax.
By setting Nmax, even if a playback switch is pressed during the sequential recording of image data on the recording medium 200 or 210 after continuous shooting, each time new image data is recorded, the image is sequentially reproduced. It is possible to update the image number N and switch the reproduction display image.

If the reproduction mode flag has been set (S1127), the system control circuit 50 proceeds to S1181.
Proceed to.

This is a state in which a series of operations in the photographing mode is temporarily suspended and a series of operations in the reproducing mode for reproducing image data recorded by photographing and recorded on the recording medium 200 or 210 is started. Or a state in which a series of operations in the reproduction mode has already been executed.

If the reproduction mode flag has been released (S1127), the flow advances to S1141.

This corresponds to a state where a series of operations in the photographing mode is being executed.

If the shutter switch SW1 has not been pressed (S1141), the flow returns to S1103.

[0327] If the shutter switch SW1 is pressed (S1141), the system control circuit 50 performs a distance measurement process to focus the photographing lens 10 on the subject, and performs a photometry process to determine an aperture value and a shutter time. Then, a distance measurement / photometry process is performed (S1142), and the process proceeds to S1143. In the photometry processing, the flash setting is also performed if necessary.

The details of the distance measurement / photometry processing S1142 are as described above with reference to FIG.

If the shutter switch SW2 has not been pressed (S1143), the system control circuit 50 determines whether the recording of new image data on the recording medium 200 or 210 has been completed (S1144).

When the recording of new image data on the recording medium 200 or 210 is completed (S1144), the system control circuit 50 updates the last recording number Nmax (S1145), and returns to S1141.

If new image data has not been recorded on the recording medium 200 or 210, or if recording has not been completed yet (S1144), the flow returns to S1141.

Thus, even when image data is being recorded on the recording medium 200 or 210 sequentially after continuous shooting, each time image data is newly recorded,
The last record number Nmax can be updated.

If the shutter switch SW2 is pressed (S1143), the system control circuit 50 updates Nnew and stores it in the internal memory or the memory 52 of the system control circuit 50 (S1146), and proceeds to S1147.

Nnew indicates that the photographed image data is stored in the recording medium 200 or 210 at the start of single shooting or continuous shooting.
Is the image number when recorded in the.

By setting this Nnew as the playback image number N in step S1126, when the playback operation is performed immediately after the shooting, the playback display is started from the first shot image data in the continuously shot images shot immediately before. It is possible to start.

The system control circuit 50 determines whether or not there is an image storage buffer area capable of storing the captured image data in the memory 30 (S1147), and stores new image data in the image storage buffer area of the memory 30. If there is no available area, a predetermined warning is displayed by image or sound using the display unit 54 (S1148), and then S11
Return to 03.

For example, immediately after the maximum number of continuous shootings that can be stored in the image storage buffer area of the memory 30 is performed,
Read from the memory 30 and read the storage medium 200 or 210
In this case, the first image to be written to the storage medium 200 or 210 is not yet recorded in the recording medium 200 or 210, and one empty area cannot be secured in the image storage buffer area of the memory 30. This is an example.

When the photographed image data is compressed and stored in the image storage buffer area of the memory 30, the amount of compressed image data differs depending on the setting of the compression mode. The area that can be stored is memory 3.
S114 whether or not the image is in the image storage buffer area
The judgment is made at 7.

If the memory 30 has an image storage buffer area capable of storing the captured image data (S114

The details of this photographing process S1149 are as described above with reference to FIG.

When the photographing process S1149 is completed, the system control circuit 50 reads out the photographed image data written in a predetermined area of the memory 30 and reads the photographed image data from the memory control circuit 22.
Various kinds of image processing are performed using the image processing circuit 20 as necessary, and compression processing for performing image compression processing according to the mode set using the compression / decompression circuit 32 is performed as necessary (S1150).

The details of this compression processing S1150 are as described above with reference to FIG.

When the compression processing S1150 has been completed, the system control circuit 50 writes the image data which has been shot and has undergone a series of processing into the free image portion of the image storage buffer area of the memory 30 (S1151). In response to this, the image storage number Mmax for the image storage buffer area of the memory 30 is updated (S1152).

With the execution of the photographing, the system control circuit 50
Reads the image data stored in the image storage buffer area of the memory 30 and
A recording medium 200 or 21 such as a memory card or a compact flash card is connected via the connector 92 or 96.
A recording process for writing to 0 is started (S115).

As described above, according to the second embodiment of the present invention, it is possible to read and display the image data last written in the image storage buffer area of the memory 30 when performing the quick review display. After reading out the image data taken from the image storage buffer area of the memory 30 and recording it on the recording medium 200 or 210, without waiting for a series of processes of reading out the image data from the recording medium 200 or 210, Thus, the captured image can be promptly displayed. In particular, a quick review display can be performed without waiting for a relatively long recording process on the recording medium 200 or 210, so that a captured image can be quickly confirmed.

When the recording of new image data on the recording medium 200 or 210 is completed (S1157), the system control circuit 50 updates the last recording number Nmax (S1158), and proceeds to S1161.

If new image data has not been recorded on the recording medium 200 or 210, or the recording of the image data has not been completed yet (S1157), the flow advances to S1161.

Thus, even when image data is being sequentially recorded on the recording medium 200 or 210 after sequential shooting, each time image data is newly recorded,
The last record number Nmax can be updated.

The system control circuit 50 determines the state of the continuous shooting flag stored in the internal memory of the system control circuit 50 or the memory 52 (S1161). If the continuous shooting flag is not set, the flow advances to S1163.

If the continuous shooting flag has been set (S1
161), the system control circuit 50 determines whether or not the shutter switch SW2 is pressed (S116).
2).

If the shutter switch SW2 has been pressed (S1162), the flow returns to S1147 to continuously perform shooting, and the next shooting is performed.

If the shutter switch SW2 has been released (S1162), the flow advances to S1163.

If the shutter switch SW1 has been pressed (S1163) when a series of continuous shootings has been completed in S1162 or a series of single shootings has been completed in S1161 (S1163). 5
0 is the internal memory of the system control circuit 50 or the memory 5
2 is determined (S116).
4) If the continuous shooting flag has been set, the process returns to S1143 in preparation for continuous shooting.

If the continuous shooting flag is not set (S
1164) The current process is repeated until the shutter switch SW1 is released (S1163).

If the shutter switch SW1 has not been pressed (S1163), the system control circuit 50 determines the state of the quick review flag stored in the internal memory of the system control circuit 50 or the memory 52 (S1165). If the quick review flag has been released, the process returns to S1103.

If the quick review flag has been set (S1165), the system control circuit 50 executes a review image selection process (S1166).

The details of this review image selection processing S1166 are as described above with reference to FIG.

[0363] As a result of executing the review image selection processing S1166, the system control circuit 50 determines whether or not a review image has been selected (S1167). If not, the process proceeds to S1169.

If the review image is selected (S1167), the image data written to the image storage buffer area of the memory 30 after photographing and performing various processes on the selected new review image Is read out, and a quick review process of displaying a review on the image display unit 28 is performed (S1168).

[0365] This quick review processing S1168 includes:
This processing is equivalent to S165, and the details thereof are as described above with reference to FIG.

The details of this frame feed processing S1192 are shown in FIG.
Will be described later.

The details of the reproduced image selection processing S1193 are as described above with reference to FIG.

[0383] Upon completion of the reproduction image selection processing S1193, the flow returns to S1103.

If the shutter switch SW1 has been pressed while displaying the reproduced image (S11).
91), the system control circuit 50
The state of the image display flag stored in the internal memory 0 or the memory 52 is determined (S1194). If the image display flag is set (S1194), the process proceeds to S1196.

If the image display flag has been cleared (S1194), the image display of the image display unit 28 is set to the OFF state (S1195), and the flow advances to S1196.

[0386] The system control circuit 50 clears the reproduction mode flag (S1196), performs various settings necessary for executing the photographing mode (S1197), and returns to S1103.

Thus, when the image is being reproduced, S
