  The operation of the embodiment of the present invention will be described with reference to FIGS.

  2 to 8 show flowcharts of a main routine of the image processing apparatus 100 according to the embodiment of the present invention.

  The operation of the image processing apparatus 100 will be described with reference to FIGS.

  Upon power-on such as battery replacement, the system control circuit 50 initializes flags, control variables, and the like (S101), and initializes the image display on the image display unit 28 to an OFF state (S102).

  The system control circuit 50 determines the setting position of the power switch 66, and if the power switch 66 is set to power OFF (S103), the display of each display unit is changed to the end state, and a flag, a control variable, etc. Required parameters, setting values, and setting modes including the image display unit 28 are recorded in the non-volatile memory 56, and a predetermined end process such as shutting off unnecessary power sources of the respective units of the image processing apparatus 100 including the image display unit 28 by the power control unit 80 is performed. After performing (S104), the process returns to S103.

  If the power switch 66 is set to power ON (S103), the system control circuit 50 determines the setting position of the mode dial 60, and if the mode dial 60 is set to one of the shooting modes (S105). ), Go to S107.

  If the mode dial 60 is set to another mode (S105), the system control circuit 50 executes a process corresponding to the selected mode (S106), and returns to S103 when the process is completed.

  The system control circuit 50 checks which shooting mode is set by the mode dial 60 (S107).

  If the mode dial 60 is set to landscape mode, depth priority (DEP) mode, panorama mode, or the like, that is, if the mode dial 60 is set to a shooting mode in which shooting is performed with a deep depth of field, enlargement is performed. The display permission flag is canceled (S109), and the process proceeds to S110.

  If the mode dial 60 is set to the shutter speed (Tv) priority mode, aperture (Av) priority mode, manual (M) mode, portrait mode, close-up mode, sports mode, night view mode, etc. If the shooting mode is set such that shooting is performed with a shallow depth of field, or shooting is possible with a shallow depth of field, an enlarged display permission flag is set (S108), S110. Proceed to

  The state of the enlarged display permission flag is stored in the internal memory of the system control circuit 50 or the memory 52.

  In this way, according to the set shooting mode, it is possible to automatically set whether to display the enlarged screen or the full screen when performing the quick review display that checks the image immediately after shooting. It becomes.

  This prevents the problem that when the enlarged screen display is set and the camera switches to a shooting mode with a deep depth of field, the enlarged screen is displayed even though it is not necessary to check the focus. I can do it.

  The system control circuit 50 determines whether or not there is a problem in the operation of the image processing apparatus 100 with respect to the remaining capacity or operation status of the power supply 86 configured by a battery or the like by the power supply control means 80 (S110). For example, after a predetermined warning is displayed by image or sound using the display unit 54 (S112), the process returns to S103.

  If there is no problem with the power supply 86 (S110), the system control circuit 50 determines whether or not the recording medium 200 or 210 is attached, acquires management information of image data recorded on the recording medium 200 or 210, and Then, it is determined whether the operation state of the recording medium 200 or 210 has a problem in the operation of the image processing apparatus 100, particularly the recording / reproducing operation of the image data with respect to the recording medium (S111). Is used to display a predetermined warning by an image or sound (S112), and the process returns to S103.

  Determination of whether or not the recording medium 200 or 210 is mounted, acquisition of management information of image data recorded on the recording medium 200 or 210, and the operation state of the recording medium 200 or 210 are the operations of the image processing apparatus 100, particularly As a result of determining whether or not there is a problem in the recording / reproducing operation of the image data on the recording medium (S111), if there is no problem, the process proceeds to S113.

  In S111, the system control circuit 50 also acquires the final recording number Nmax of the image data recorded on the recording medium 200 or 210.

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

  The system control circuit 50 displays various setting states of the image processing apparatus 100 using images and sounds using the display unit 54 (S113). If the image display of the image display unit 28 is ON, the image display unit 28 is also used to display various setting states of the image processing apparatus 100 using images and sounds.

  The system control circuit 50 checks the setting state of the quick review setting switch 68 for setting the quick review function for automatically reproducing the captured image data immediately after shooting (S114). If the quick review is set to ON, the quick review is set. A flag is set (S115), and the process proceeds to S117.

  If the quick review OFF is set, the system control circuit 50 cancels the quick review flag (S116), and proceeds to S121.

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

  When performing the quick review display, the system control circuit 50 checks whether the full screen display or the enlarged screen display is set (S117), and is set to the full screen quick review display. Then, a full screen quick review display flag is set (S119), and the process proceeds to S121. If the enlarged screen quick review display is set, an enlarged screen quick review display flag is set (S118), and the process proceeds to S121.

  The state of the full screen quick review display / enlarged screen quick review display flag is stored in the internal memory of the system control circuit 50 or the memory 52.

  If a series of shooting and recording sequences have already been executed and the image data recorded on the recording medium 200 or 210 is being recorded, the recording of new image data on the recording medium 200 or 210 is completed. If so (S121), the system control circuit 50 updates the final recording number Nmax (S122), and proceeds to S123.

  If new image data is not recorded on the recording medium 200 or 210, or if recording of the image data is not yet completed (S121), the process proceeds to S123.

  This makes it possible to update the final recording number Nmax every time image data is newly recorded, even when image data is being sequentially recorded on the recording medium 200 or 210 after continuous shooting. Become.

  The system control circuit 50 determines whether the regeneration switch 66 is set to ON or OFF (S123).

  If the reproduction switch 66 is set to OFF (S123), the process proceeds to S129.

  Thus, if the playback switch 66 is OFF, it is either in a state in which a series of operations in the shooting mode is being executed, or in a state in which a series of operations in the playback mode has already been executed. It is determined that there is, and the process proceeds to S129 without performing the processes after S124. Whether or not the playback mode has already been executed can be determined using a playback mode flag, as will be described later.

  If the regeneration switch 66 is set to ON (S123), the system control circuit 50 determines the state of the regeneration mode flag (S124).

  If the playback mode flag has been set, that is, if it is determined that the playback mode has already been executed (S124), the system control circuit 50 determines whether or not the final recording number Nmax has been updated ( If it has been updated, the process proceeds to S128. If it has not been updated, the process proceeds to S129.

  Thus, even if the regeneration switch 66 is ON, if the regeneration mode flag has already been set, it is determined that a series of operations in the regeneration mode has already been performed, and S125 to S127. The process proceeds to S128 without performing the above process.

  If the reproduction mode flag has been released, that is, if it is determined that the reproduction mode is newly executed (S124), the system control circuit 50 sets the reproduction mode flag (S125), and the process goes to S126. move on.

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

  Thus, if the playback mode flag is cleared when the playback switch 66 is ON, the shooting mode is currently being executed, but SW1 and SW2 are not being pressed, so the shooting operation is performed. Can be determined to be in an unexecuted state. Then, a series of operations in the shooting mode is paused, and a series of operations in the reproduction mode in which the image data recorded on the recording medium 200 or 210 is reproduced is started.

  Subsequently, the system control circuit 50 performs a predetermined setting necessary for executing the reproduction mode (S126), and then is read in S111 and stored in the internal memory or the memory 52 of the system control circuit 50. The recording number Nmax is read (S127), and the process proceeds to S128.

  Then, the system control circuit 50 sets the reproduction image number N as N = Nmax (S128), and proceeds to S129.

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

  As a result, it is possible to read and display the image data last recorded on the recording medium 200 or 210 without performing image selection using the image selection key immediately after executing the reproduction mode. Convenient.

  If the final recording number Nmax has been updated, the image data is sequentially recorded on the recording medium 200 or 210 after continuous shooting by setting the reproduction image number N as N = Nmax accordingly. Even when the playback switch is pressed in the middle of recording, the playback display image can be switched by sequentially updating the playback image number N every time recording of new image data is completed.

  If the playback mode flag has been set (S129), the system control circuit 50 proceeds to S201.

  This is a state in which a series of operations in the shooting mode is temporarily paused, and a series of operations in the playback mode in which the image data recorded and recorded on the recording medium 200 or 210 is started, or One of the states in which a series of operations in the playback mode has already been performed corresponds to this.

  If the playback mode flag has been canceled (S129), the process proceeds to S141.

  This corresponds to a state in which a series of operations in the shooting mode is being executed.

  If the shutter switch SW1 is not pressed (S141), the process 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 10 on the subject, performs a photometry process, and determines an aperture value and a shutter time. Distance measurement / photometry processing is performed (S142), and the process proceeds to S143.

  In the photometric process, the flash is set if necessary.

  Details of the distance measurement / photometry processing S142 will be described later with reference to FIG.

  If the shutter switch SW2 has not been pressed (S143), the system control circuit 50 determines whether or not new image data has been recorded on the recording medium 200 or 210 (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 final recording number Nmax (S145) and returns to S141.

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

  This makes it possible to update the final recording number Nmax every time image data is newly recorded, even when image data is being sequentially recorded on the recording medium 200 or 210 after continuous shooting. Become.

  If the shutter switch SW2 is pressed (S143), 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 (S146), and the quick review flag is set. If so, the display of the image display unit 28 is set to the OFF state (S147), and the process proceeds to S148.

  If the quick review flag has been canceled (S146), the process proceeds to S148.

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

  For example, immediately after performing the maximum number of continuous shots that can be stored in the image storage buffer area of the memory 30, the first image to be read from the memory 30 and written to the storage medium 200 or 210 is still in the recording medium 200 or 210. An example of this state is an unrecorded state where one empty area cannot be secured in the image storage buffer area of the memory 30 yet.

  When the captured image data is compressed and stored in the image storage buffer area of the memory 30, it can be stored in consideration of the fact that the amount of compressed image data varies depending on the compression mode setting. Whether or not the area is on the image storage buffer area of the memory 30 is determined in S148.

  If there is an image storage buffer area capable of storing captured image data in the memory 30 (S148), the system control circuit 50 includes the image sensor 12, the A / D converter 16, the image processing circuit 20, and the memory control circuit 22. Via the A / D converter or directly from the A / D converter via the memory control circuit 22, the exposure process for writing the image data taken in a predetermined area of the memory 30, and the memory control circuit 22 and, if necessary, the image processing circuit 20 Then, the image processing written in the predetermined area of the memory 30 is read and the photographing process including the developing process for performing various processes is executed (S150).

  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 the photographed image data written in a predetermined area of the memory 30, and performs various image processing using the memory control circuit 22 and, if necessary, the image processing circuit 20. In addition, a compression process for performing an image compression process according to the mode set by using the compression / decompression circuit 32 is performed as necessary (S151).

  Details of the compression processing S151 will be described later with reference to FIG.

  When the compression process S151 is completed, the system control circuit 50 writes the image data that has been photographed and completed a series of processes in the empty image portion of the image storage buffer area of the memory 30 (S152). The image storage number Mmax for the image storage buffer area of the memory 30 is changed (S153).

  Along with the execution of shooting, the system control circuit 50 reads the image data stored in the image storage buffer area of the memory 30, and the memory card or compact flash (registered trademark) via the interface 90 or 94 and the connector 92 or 96. Recording processing for writing to the recording medium 200 or 210 such as a card is started (S154).

  This recording start process is performed on the image data every time new image data that has been shot and finished a series of processes is newly written in the empty image portion of the image storage buffer area of the memory 30.

  Note that while writing image data to the recording medium 200 or 210, in order to clearly indicate that the writing operation is being performed, the display unit 54 performs a recording medium writing operation display such as blinking an LED.

  When the recording of new image data on the recording medium 200 or 210 is completed (S155), the system control circuit 50 updates the final recording number Nmax (S156), and proceeds to S161.

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

  This makes it possible to update the final recording number Nmax every time image data is newly recorded, even when image data is being sequentially recorded on the recording medium 200 or 210 after continuous shooting. Become.

  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 has been set (S161), the system control circuit 50 determines whether or not the shutter switch SW2 has been pressed (S162).

  If the shutter switch SW2 has been pressed (S162), the process returns to S146 to perform continuous shooting, and the next shooting 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 (S163), and the quick review. If the flag has been canceled, the process proceeds to S181.

  If the quick review flag has been set (S163), the system control circuit 50 sets the review image number M as M = Mmax (S164) and selects image data for the review image number M (S165). The selected image data is read from the image storage buffer area in the memory 30 (S166), the image decompression process for the read image data is performed by the image compression / decompression circuit 32 (S167), and the image subjected to the image decompression process is stored in the memory 30. In the image storage buffer area.

  The system control circuit 50 determines the state of the full screen quick review display / enlarged screen quick review display flag stored in the internal memory of the system control circuit 50 or the memory 52 (S168).

  If the full screen quick review display flag has been set (S168), the system control circuit 50 changes the setting state of the memory control circuit 22 to full screen display (S171), and proceeds to S172.

  If the enlarged screen quick review display flag is set (S168), the system control circuit 50 determines the state of the enlarged display permission flag stored in the internal memory of the system control circuit 50 or the memory 52 (S169), If the enlarged display permission flag has been set (S169), the setting state of the memory control circuit 22 is set to the enlarged screen display (S170), and the process proceeds to S172.

  On the other hand, if the enlarged display permission flag has been canceled (S169), the process proceeds to S171.

  As described above, even when the enlarged display quick review display is set, when the enlarged display permission flag is not set, that is, when the shooting mode is set to perform shooting with a deep depth of field. However, it is possible to prevent a problem that an enlarged screen is displayed even though it is not necessary to check the focus.

  The system control circuit 50 reads out the stored image data from the image storage buffer area of the memory 30 and executes display image processing for transferring to the image display memory 24 via the memory control circuit 22 (S172). ).

  The system control circuit 50 sets the image display of the image display unit 28 to the ON state (S173), reads the display image data transferred in S172 from the image display memory 24, reads the memory control circuit 22, and the D / A converter 26. The quick review display to be displayed by the image display unit 28 is performed (step S174), and the process proceeds to step S181.

  As described above, according to 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 the image data taken from the area is read out and recorded on the recording medium 200 or 210, the taken image is displayed promptly without waiting for a series of processes to read out the image data from the recording medium 200 or 210 to end. I can do it. In particular, the quick review display can be performed without waiting for the recording process to the recording medium 200 or 210, which takes a relatively long time, so that the captured image can be confirmed quickly.

  If the shutter switch SW1 has been pressed at the end of S174 (S181), 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. If the continuous shooting flag is set (S182), the process returns to S143 in preparation for continuous shooting.

  If the continuous shooting flag is not set (S182), the current processing is repeated until the shutter switch SW1 is released (S181).

  If the shutter switch SW1 has not been pressed (S181), 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 (S183). If the review flag has been canceled, the process returns to S103.

  If the quick review flag has been set (S183), the system control circuit 50 determines the display setting state (S184).

  If the display setting state is set to the full screen display state (S184), the process proceeds to S190.

  If the display setting state is set to the enlarged screen display state (S184), the process proceeds to S185.

  When the “+” key included in the operation unit 70 is pressed (S185), the system control circuit 50 scrolls the quick review display area in the forward direction (S187), and the “−” key included in the operation unit 70. If is pressed (S186), the quick review display area is scrolled in the reverse direction (S188), the quick review display screen is updated (S189), and the process proceeds to S190.

  The system control circuit 50 returns to S184 and performs a series of processes until a predetermined minimum review time has elapsed (S190) while scroll display of the quick review screen is performed as necessary.

  As described above, by continuing the quick review display in the image display unit 28 for a predetermined time, it is possible to surely check the photographed image, and the quick review display is continued unnecessarily for a long time. It is possible to prevent losing a shooting opportunity.

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

  If the minimum review time has elapsed (S190), the system control circuit 50 sets the display of the image display unit 28 to the OFF state (S191), ends a series of shooting operations, and returns to S103.

  The system control circuit 50 reads the reproduction image number N stored in the internal memory of the system control circuit 50 or the memory 52, selects reproduction image data corresponding to the reproduction image number N (S201), and then corresponding image data. Is present in the memory 30 (S202).

  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 assigns the image data existing in the image storage buffer area in the memory 30 as read from the storage medium. (S203). In this case, since the read operation from the storage medium 200 or 210 is unnecessary, the reproduction display operation can be started at high speed.

  If the image data corresponding to the reproduced image data does not exist in the memory 30 (S202), the system control circuit 50 receives the connector 92 or 96 from the recording medium 200 or 210 such as a memory card or a compact flash (registered trademark) card. Then, a recording medium reading process is executed in which the image data corresponding to the reproduction image number N is read via the interface 90 or 94 and stored in the image storage buffer area of the memory 30 (S204).

  The system control circuit 50 performs image decompression processing on the read image data by the image compression / decompression circuit 32 (S205), and stores the image subjected to the image decompression processing in a predetermined area in the memory 30.

  The system control circuit 50 determines the setting state of the full screen display / enlarged screen display switch 74 (S206), and if it is set to the enlarged display (S206), sets the setting state of the memory control circuit 22 to the enlarged screen display. (S208) If set to full screen display (S206), the setting state of the memory control circuit 22 is set to full screen display (S208), and the process proceeds to S209.

  The system control circuit 50 executes display image processing in which image data stored by performing image decompression processing is read from a predetermined area of the memory 30 and transferred to the image display memory 24 via the memory control circuit 22 (S209).

  The system control circuit 50 sets the image display of the image display unit 28 to the ON state (S210), reads the display image data transferred in S209 from the image display memory 24, reads the memory control circuit 22, and the D / A converter 26. Is displayed by the image display unit 28 (S211).

  If the shutter switch SW1 has been released while displaying the replay image (S212), the process proceeds to S221.

  If the shutter switch SW1 has been pressed while displaying the reproduced image (S212), the system control circuit 50 displays the image display flag stored in the internal memory of the system control circuit 50 or the memory 52. If the image display flag has been set (S213), the process proceeds to S215.

  If the image display flag has been canceled (S213), the image display of the image display unit 28 is set to the OFF state (S214), and the process proceeds to S215.
