Field of the Invention The present invention relates to a digital still camera and an image data processing method thereof, and more particularly, to a method of converting photographed image data into digital data, and performing image processing on the obtained digital image data to a recording medium. The present invention relates to a digital still camera for writing data into a digital still camera and an image data processing method thereof.

[0002]

2. Description of the Related Art A conventional digital still camera of this type detects an operator pressing a shutter button, A / D converts analog image data taken from an image sensor such as an image sensor, and further complements pixels. And JPEG (Joint Ph)
autographic coding Experts
The data is compressed into a file format such as Group, stored in a recording medium such as a compact flash card, and is used to create image data that can be used by another information processing apparatus such as a personal computer.

[0003] The setting of image processing and the format of data recorded on a recording medium can be set by an operation of an operator.

For example, Japanese Patent Laid-Open Publication No. Hei 7-274108 has a mode changeover switch which is set to be switchable between a compression mode and a non-compression mode, and a JPEG format according to the mode set by the changeover switch. Or TIFF (TagImage File Fo)
(rmat) format is disclosed in which image data is written to a memory card.

[0005]

However, in the above-described digital still camera, when the shutter button is pressed, the mode set by the mode changeover switch is read, and data processing is performed according to the mode, and the data is recorded on the recording medium in that format. Even if you notice on the way that the type of image data format set as the shooting condition is different from the setting intended by the user,
There is a problem that the image data of the intended setting cannot be obtained unless the photographing is performed again until the writing to the recording medium in the set format is completed. Further, in recent years, the number of pixels of image data has tended to increase more and more due to a demand for higher quality of a captured image, and accordingly, the processing time of image data and the recording time on a recording medium have increased, and When a plurality of images are to be photographed, it is becoming difficult for the user to photograph again and perform data processing.

An object of the present invention is to provide a method for recording image data on a recording medium with a setting different from an intended setting immediately after photographing, before completing the data processing on the photographed image. Another object of the present invention is to provide a digital still camera capable of accepting a setting change and quickly obtaining an image processed with the changed setting.

[0007]

A digital still camera according to the present invention includes an image sensor that captures a subject and outputs analog image data, an AD converter that converts the analog image data into digital data, and the AD converter. A first recording medium for storing the image data converted into digital data in the first recording medium, and a plurality of image data processes preset for the image data when the image data is stored in the first recording medium. A control unit that continuously converts the digital image data after the plurality of image data processings into a preset storage format, a second recording medium that stores the digital image data converted into the storage format, In a digital still camera having an operation unit for setting a content of a plurality of image data processing and a storage format in the second recording medium, the control unit includes: Immediately before a predetermined image data process, the plurality of image data processes are performed while storing the image data before the image data process in the first recording medium, and the contents of the plurality of image data processes are stored in the operation unit. When the first image data processing is changed by the above operation, the first image data processing to be performed with the content according to the content of the operation is determined, and the image data processing performed earlier than the second image data processing during the processing is determined. In some cases, the second image data processing is stopped halfway, and the second image data processing is stopped immediately before the first image data processing .
The first image data processing is started with the changed settings for the image data stored in the first recording medium .

According to the present invention, when the operator notices that the image data is being recorded on the recording medium with the settings different from the intended settings immediately after the photographing, the operating section is operated to change the settings. If it is changed, image data processing and data data in a data format according to a desired condition can be obtained quickly based on the operation.

In the digital still camera according to the present invention, the control section starts the conversion process after storing the image data before the conversion process in a first recording medium.

According to the present invention, for example, when the image size is changed in a direction to reduce the image size after the process of converting a plurality of image processes to the storage format is started on the operation unit, the first recording medium It is possible to reduce the size of the image by reducing the pixels constituting the image with respect to the stored image before conversion. Similarly, when an operation of changing the direction of the image is performed, a rotation process of rotating the image with respect to the image before conversion can be performed. Further, when an operation of changing the storage format in the second recording medium is performed, the image before conversion is converted into a new format. Also,
When the data capacity is compressed in the conversion process, when the compression rate is changed, the image before conversion can be converted at a new compression rate. Therefore, it is possible to quickly obtain image data corresponding to a desired condition for various setting changes.

In each of the above inventions, when the control unit includes a rotation process of rotating the image data by 90 degrees in the plurality of image data processes, the control unit converts the image data before the rotation process into a first image data. after storing the recording medium, the have line rotation processing, the rotation processing said first image data
And the rotation processing is performed on the second image data.
If the image data processing is performed before the data processing
The second image data processing is stopped halfway and the rotation processing is stopped.
Image data stored in the first recording medium immediately before processing
If the changed setting does not require rotation processing
The image data stored in the first recording medium is
The image data processing after the rotation processing is performed .

According to the present invention, for example, when the control unit is performing a process of rotating an image created by the landscape port by 90 degrees by initially setting the portrait, the direction of the image is set after the rotation process. When changing from a rate to a landscape, the landscape image that was originally created can be used and the subsequent processing can be redone, so that the direction of the image can be quickly changed.

In each of the above inventions, when the plurality of image data processes include a thinning process of thinning pixels constituting image data to reduce an image size, the control unit may be configured to execute the image data before the thinning process. Is stored in the first recording medium, and then the thinning process is performed.
It is determined that the processing is the first image data processing, and
Subtraction processing is performed before the second image data processing
When the image data processing is the second image data processing
Immediately before the thinning-out process, and
The thinning process is started with the changed settings for the image data stored in the recording medium .

According to the present invention, when the image size is changed in the direction of increasing the image size with respect to the operation unit after the start of the thinning process, the changed image is compared with the image stored in the first recording medium. You can start the thinning process based on the size, and if other processes are performed before the thinning process, you can start the process from the thinning process, so the image size changes in the direction to enlarge the image size In this case, the image size can be changed quickly and without deteriorating the image quality.

In the case where the plurality of image data processes include the rotation process and an image quality change process for changing image quality such as contrast and color tone, the image after the image quality change process is processed.
The data after storing the first recording medium, and starts the rotation processing.

According to the present invention, for example, when only the image direction is changed, the image quality change processing does not need to be performed again, and the image direction can be changed quickly.

And a switch controller 20 for monitoring pressing of various switches.

The digital system control ASIC 6 converts an image formed on the image sensor 1 by the lens into electric charges by the image sensor 1, amplifies the image by the amplifier 3, and converts the image into a digital signal by the A / D converter 4. The obtained raw image data is transferred to and stored in the DRAM 5 by the DMA function.

The digital control ASIC 6 generates image data for display by performing thinning-out processing or the like based on raw image data before executing an image processing program by the CPU 7 described later, and writes the generated image data to the VRAM 10. VRAM1
The image data written to 0 is the analog control ASI
It is displayed on the display panel 11 by C12.

The CPU 7 has a ROM 21 and a ROM 2
The lens and the aperture actuator 2 are operated via the digital control ASIC 6 based on the control program stored in 1 to adjust the focus and exposure of the image to be shot.

The compact flash card 8 is 8 MB

The data is written to the card 8 via the write buffer 9. At this time, before performing a series of processes, the image data before the process is saved before some predetermined processes in the middle.

In the pixel interpolation process, a known process of calculating the value of each color in all pixels is performed using data that is discrete for each color in the image data obtained by the image sensor.

When the PEG format is specified, the compression ratio is switched. These settings are stored in the ROM 21 of the CPU 7 in an image processing setting table for storing the settings of each image processing as shown in FIG. 2, and when the depression of various switches is detected, the CPU 7 executes the image processing setting table. And by rewriting the contents of the corresponding table.

Further, in the image processing setting table, a file name for saving image data before a predetermined processing in the course of performing a series of processing is written together with various setting contents.

Next, the operation of this embodiment will be described with reference to FIG.

FIG. 3 is a flowchart showing a series of processes from photographing an image by detecting press of the shutter switch 15 to performing image processing and completing writing to the compact flash card.

First, the digital control ASIC 6 monitors the depression of the shutter switch 15 (step S1). When the depression of the shutter switch 15 is detected, the lens and the diaphragm actuator 2 are operated, and the subject whose focus and exposure are adjusted is controlled. An image is formed on the surface of the image sensor 1, and then the image sensor 1 is controlled and exposed for a predetermined time by an electronic shutter function of the image sensor 1, and the charge generated in the image sensor 1 is subjected to AD conversion as described above. The digital system control ASIC 6 transfers the digital signal to the DRAM 5 using the DMA function and stores the digital signal (step S2). At this time, an identification number for identifying the image stored in the DRAM 5 is given, and an image processing setting table corresponding to the identification number is created. At this time, the contents set by the user by operating various switches up to that point are written.

Next, pixel complement processing is performed on the raw image data stored in the DRAM 5 (step S3).
Next, the image data after the pixel complementation processing is stored in the DRAM 5 as a file different from the raw image data (step S).
4). Next, referring to the contents of the image processing setting table, check the settings relating to the image size specified in advance by the user, determine whether it is necessary to reduce the image size, and set the image size smaller than the raw image data. If so, it is determined that the image needs to be reduced, and the image size is reduced by performing a thinning process of thinning out the pixels constituting the image (step S5). At this time, the file name is written in the above-described image processing setting table as a file before the thinning processing. If there is no need to reduce the image size, no thinning process is performed.

Next, by referring to the contents of the image processing setting table, the settings relating to image quality such as sharpening and color tone specified by the user are confirmed, and the image quality such as sharpening and color tone conversion is determined based on the settings. An image quality changing process to be changed is performed (step S6).

Next, referring to the contents of the image processing setting table, the user checks the settings relating to the image direction specified by the user, and rotates the image based on the image direction specified by the user based on the settings. It is determined whether or not it is necessary to carry out (Step S7). If necessary, the image data before the rotation processing is stored in a file different from the raw image data, and the arrangement of the image data is converted to perform the rotation processing (step S8). At this time, the file name is written in the image processing setting table as a file before rotation processing. Next, the image data is stored in a file different from the raw image data and the data after the image processing before the conversion into the storage format in the compact flash card 8 specified by the user in advance (step S9). Also at this time, the file name is written in the image processing setting table. Next, image data format conversion processing is performed, and the write buffer 9
(Step S10). The image file that has been converted into the predetermined data format and has been written into the write buffer 9 is written and stored in the compact flash card 8 (step S11).

Next, a description will be given of an operation of the embodiment of the present invention in the case where there is an interruption due to the pressing of various switches during the above operation or after the operation is completed and before the shutter button is pressed next.

FIGS. 4 to 7 are flowcharts showing the operation when various processing contents are changed by pressing various switches during the operation. FIG. 4 is a flowchart showing the operation performed when the image direction setting switch 16 is pressed by determining the pressed switch, and FIG. 5 is a flowchart showing the operation performed when the image size setting switch 17 is pressed. FIG. 6 is a flowchart showing an operation performed when the storage format setting switch 18 is pressed, and FIG. 7 is a flowchart showing an operation performed when the compression ratio setting switch 19 is pressed.

Referring to FIG. 4, first, it is determined which switch has been pressed (step S21). It is determined whether or not the switch is the image direction setting switch 16 (step S22). If the switch is the image direction setting switch 16, the CPU 7 that has accepted the interrupt refers to the image processing setting table stored in the ROM 21 to determine the image direction. The setting contents are rewritten (step S23), and the image processing corresponding to the changed contents is determined to be step S7 (step S24).
Then, the CPU 7 determines that the current processing is performed in step S7.
It is determined whether the process is performed earlier (step S25).
Here, if the current processing is processing performed before step S7 corresponding to the above-described content change, the current processing is continued as it is, and based on the changed image processing setting table in FIG. The processing is sequentially advanced according to the flowchart of (Step S26). If the current processing is during or after step S7, the image processing setting table is referred to and it is checked whether the changed setting requires rotation processing (step S27). . If the setting after the change requires rotation processing, the rotation processing before the change was not necessary, and thus the image file before the rotation processing is not stored. Therefore, it is determined in step S9 whether the storage of the file before format conversion has been completed, and if not completed, the process waits for completion (step S2).
8). Then, the image data is read from the file before format conversion with reference to the image processing setting file, and the step S8 of the rotation process is performed (step S29). Then, the processing from step S9 to S11 is sequentially performed (step S9).
30). If the setting after the change does not require the rotation processing, the image data is read from the pre-rotation processing file of the image processing setting table (step S31), and step S9 to step S11 are performed without performing step S8. (Step S3)
2).

If the switch is not the image direction setting switch 16 in step S22, referring to FIG. 5, it is determined whether the switch is the image size setting switch (step S3).
3). In the case of the image size setting switch, it is checked whether the image size has been changed in the direction of increasing or decreasing, with reference to the image processing setting table (step S34). For example, when the image size is alternately switched between, for example, XGA and VGA as described above, if the content of the image reference table before change is VGA, it is determined that the direction is to increase, and if the content is XGA, the size is reduced. Judge as the direction.

When the direction is increased, the setting of the image direction in the image processing setting table is rewritten (step S35), and the corresponding image processing is executed in step S5.
Is determined (step S36). Then, the CPU 7 determines whether or not the process currently being performed is a process performed before step S5 (step S37). Here, if the current processing is processing performed before step S5 corresponding to the above-described content change, the current processing is continued as it is, and based on the changed image processing setting table in FIG. The processing is sequentially performed according to the flowchart of (1) (step S38).

If the current processing is step S5 or a subsequent processing, the image data is read from the file before the thinning processing by referring to the image processing setting table, and the thinning processing in step S5 is performed. (Step S39). Then, the processes from step S6 to S11 are sequentially performed (step S30).

If it is determined in step S34 that the image size has been changed in the direction of reducing the image size, the setting of the image direction in the image processing setting table is rewritten (step S41), and the image processing corresponding to the content change is performed. It is determined as Step S10 (Step S42). And CPU7
Determines whether the current process is a process performed before step S10 (step S43). Here, if the currently performed processing is processing performed before the corresponding step S10, the currently performed processing is continued as it is, and sequentially based on the changed image processing setting table according to the flowchart of FIG. The process proceeds (step S44).

If the current processing is step S10 or a subsequent processing, the image data is read from the file before the format conversion processing by referring to the image processing setting table, and the thinning processing in step S5 is performed. Perform (Step S45). Then, the processes of steps S10 and S11 are sequentially performed (step S46).

If the switch is not the image size setting switch 17 in step S33, referring to FIG. 6, it is determined whether the switch is the storage format setting switch 18 (step S4).
7) In the case of the storage format setting switch, the setting content of the storage format in the image processing setting table is rewritten (step S
48), performing image processing corresponding to the content change in step S10
Is determined (step S49). Then, it is determined whether or not the process currently being performed is a process to be performed before step S10 (step S50). If the current process is a process to be performed before the corresponding step S10, the current process is continued as it is, and based on the changed image processing setting table, sequentially proceeds to step S11 according to the flowchart of FIG. Proceed with the process (Step S5
1).

If the current processing is step S10 or a subsequent processing, the image data is read from the file before the format conversion processing by referring to the image processing setting table, and step S10 is performed with the changed setting. The format conversion process of S10 is performed (step S52). And step S
11 are sequentially performed (step S53).

If the switch is not the storage format setting switch 18 in step S47, referring to FIG. 6, it is determined whether the switch is the compression ratio setting switch 19 (step S5).
4) In the case of the compression ratio setting switch 19, the image processing setting table is referred to, and it is checked whether or not the storage format allows the compression ratio to be set (step S55). If the switch is not a compression ratio setting switch or is not in a format that can be compressed, the current processing is continued as it is, and step S
The processing is sequentially performed up to 11 (step S56). If the format is compressible, the setting content of the compression ratio in the image processing setting table is rewritten (step S57), and the corresponding image processing is determined to be step S10 (step S58). Then, the CPU 7 determines whether or not the currently performed process is a process to be performed after step S10 corresponding to the content change (step S59). If the current process is a process to be performed before the corresponding step S10, the current process is continued as it is, and based on the changed image processing setting table, sequentially proceeds to step S11 according to the flowchart of FIG. Processing proceeds (step S60),
If the current process is step S10 or a subsequent process, the image data is read from the file before format conversion processing by referring to the image processing setting table, and the format of step S10 is read with the changed settings. The conversion process is performed (step S61), and the process of step S11 is performed (step S62).

As described above, in the digital still camera of the present invention, the switch controller 20 is provided separately from the processing from the detection of the depression of the shutter switch to the writing of the image data to the compact flash card 8.
Monitors various operation switches for image processing and setting of a file format. When the operation switches are pressed, the CPU interrupts the CPU 7 via the digital system control ASIC 6, and the CPU 7 outputs the raw image data. DRAM5
After saving, this interrupt is accepted, if necessary, the data being processed is discarded, and the DR is newly set based on the function assigned to each operation switch.
Since image processing of the raw image data on the AM 5, conversion of the stored image file format, and writing processing to the compact flash card 8 are performed, a series of image processing started by a shutter switch and during or during writing processing to the compact flash card Later, as soon as the operation switch is pressed, image processing, conversion to an image file format, and writing to the compact flash card 8 are performed with new settings, and image data is stored in the DRAM 5 by the DMA function in the next shooting. Until is transmitted, the user can change the image processing conditions any number of times.

When the continuous shooting mode is set, a plurality of pieces of raw image data are stored in the DRAM 5, and respective image processing setting tables are created to record the corresponding raw image data files and intermediate storage file names. Image processing is sequentially performed, the file format is converted, and the file format is written to the compact flash card. In this case, when the setting is changed, the process returns to the image processing of the first sheet and refers to the image processing setting table of the first sheet, and the contents are changed according to the image processing whose contents have been changed. After the corresponding intermediate storage file is read in accordance with the flowchart of the above and the writing process is completed with the new settings, the second image processing is performed by referring to the image processing setting table of the second image in the same manner as the first image. Based on the corresponding flowchart, the corresponding intermediate storage file is read based on the corresponding flowchart, and the processing up to the writing processing is completed with the new setting, and the processing up to the last image processing performed by continuous shooting is performed thereafter.

Also, when the battery is consumed, the DRAM
The digital control ASIC 6 has a function of monitoring the voltage of the battery, which is the power supply 14, in order to prevent the raw image data stored in the DRAM from disappearing. The raw image data
7 to the ROM 21 or the compact flash card 8. In this case, after the power supply voltage has dropped below the level at which the battery is judged to be exhausted, if the battery level has recovered to a level at which the battery level is judged to be sufficient, the ROM 21 of the CPU 7 or the compact flash card Raw image data transferred to
The image may be transferred to the AM 5 so that the image processing setting can be changed for the image.

[0053]

As described above, the present invention has the following effects.

The first effect is that the setting conditions of the image processing can be changed even after the start of the image processing.

The reason is to detect the pressing of the operation button by the user of the apparatus, to discard the contents of the image processing by the interruption processing, and to execute the processing again according to the changed condition.

The second effect is that the image processing conditions can be changed until the next photographing is performed. The reason is that the raw digital image data is stored in the DRAM until the next shot is taken.
Since it is held above, the operation of the device user again
This is for performing the process based on the changed condition.

The third effect is that even when the setting of the image size is changed in the direction of enlargement, the processing can be performed quickly and with little image deterioration even when the processing is performed again.

The reason is that when the setting of the image size is changed, it is determined whether or not the image size is to be enlarged, and in the case of the enlargement, the image before the reduction is used instead of the image once reduced. That's why.
