Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a digital still camera incorporating a print reproduction apparatus of the present invention.
As shown in the figure, the digital still camera includes an input device 2 that converts light from a subject 50 incident on the camera body 1 from an optical system into an electrical signal, and temporarily stores the electrical signal as image data. Display frame memory 3 (= image storage means), image processing apparatus 4 (= image processing means) for performing image processing on image data stored in the frame memory 3, and image data subjected to image processing are displayed. Display device 5.

  The digital still camera further includes a key operation unit 6 that performs various operations such as a photographing operation that gives a photographing instruction, a buffer memory 7 that temporarily stores image data that has undergone image processing, and an imaging operation. A memory card 8 that records image data recorded in the buffer memory as photographed image data, a microcomputer 9 that controls the operation of each unit and each device, and the photographed image data recorded in the memory card 8 are printed out and reproduced. And a print output device 10 (= image reproduction means).

  In the embodiment of the present invention, the case where the print output device 10 is built in the digital camera will be described as an example. However, the digital camera and the print output device 10 are in separate housings. There is also.

  The input device 2 includes, for example, an optical lens unit (= optical system) (not shown), an imaging device (CCD: charge coupled device) that receives light from a subject and outputs an analog electric signal, and a CCD (= photoelectric conversion means). A control signal generator (TSG: timing signal generator) to be driven, an analog (A) / digital (D) converter for converting analog image data output from the CCD into digital image data, and the like are included. In the frame memory 3, digital image data input from the input device 2 is temporarily stored.

  The image processing apparatus 4 includes an image processing unit 4a that performs adjustment of a white balance gain, an edge enhancement coefficient, a gamma conversion coefficient, and the like. The color conversion coefficient is a coefficient for adjusting the hue of the image data, the edge enhancement coefficient is a coefficient for adjusting the contour (edge) of the image data, and the gamma conversion coefficient is the brightness of the image data. It is a coefficient for adjusting the thickness.

  The image processing device 4 is also used when storing the image data in the memory card 8 and the display control unit 4b that performs control for causing the display device 5 to display the image data processed by the image processing unit 4a. A data compression unit 4c that performs data compression processing on image data in order to reduce the storage capacity, and data expansion processing on image data in order to increase the storage capacity used when storing the image data in the memory card 8 And a data decompression unit 4d for performing the above.

  The image processing unit 4a converts image data composed of R, G, and B colors output from the input device 2 into data composed of luminance Y and color differences Cb and Cr. The microcomputer 9 includes a central processing unit (CPU), a read only memory (ROM), a write / read memory (RAM), etc., not shown.

A general operation of the camera having the above-described configuration will be described below.
When the power switch is turned on, the microcomputer 9 opens a shutter (not shown), and forms a subject image on the CCD in the input device 2 via the lens. The CCD converts the subject image into an electrical signal and outputs it as analog image data composed of R, G, and B colors. The analog image data is converted into a digital image signal by an A / D converter. The converted digital image data is stored in the frame memory 3.

  Next, the microcomputer 9 reads the specific portion of the digital image data stored in the frame memory 3 or the entire R, G, and B values, and sets the white balance gains Gr0 and Gb0 so as to obtain an image of an appropriate hue. calculate.

  The image processing unit 4 a converts the image data composed of R, G, and B colors into Y, Cb, and Cr image data of luminance and color difference and outputs them to the buffer memory 7. When performing this image conversion, the image processing unit 4a uses the white balance gains Gr0 and Gb0 calculated by the microcomputer 9 to perform white balance adjustment of the image data. The white balance adjustment is performed and the image data stored in the buffer memory 7 is sent to the display device 5 via the image processing device 4 and displayed. The above operation is repeated every predetermined time (for example, every 1/30 s).

  Next, auto bracket (AB) shooting will be described. AB shooting is shooting in which a set of shot image data having different image parameter values such as hue, contour, and brightness is recorded in the memory card 8 in accordance with one shooting operation.

  In the present embodiment, in AB shooting, for example, by performing image processing while changing the white balance gain, a set of shot image data having different hues is obtained. Further, by performing image processing while changing the edge enhancement coefficient, a set of photographed image data having different contours is obtained. Further, by performing image processing with different gamma conversion coefficients or shooting with different exposure values, a set of captured image data with different brightness of the subject is obtained.

  Next, the photographing operation of the digital still camera when the AB photographing mode in which a set of three pieces of photographed image data having different colors is recorded in accordance with one photographing operation will be described below.

  When a photographing operation is performed by the key operation unit 6, the above-described white balance adjustment is performed, and the image data stored in the buffer memory 7 is read into the data compression unit 4 c in the image processing device 4, for example, by JPEG compression. Compressed. Next, the microcomputer 9 functions as a data recording unit and a file creation unit. The compressed image data is used as the first photographed image data, and an image file including the first shot image data is created. Record on card 8.

  Next, the microcomputer 9 uses the white balance gains Gr1 and Gb1 (Gr1 <Gr0, Gb1> Gb0) such that the hue of the image data stored in the frame memory 3 at the next timing becomes blue. Is processed by the image processing apparatus 4, and after compression, an image file including the second captured image data is created and recorded in the memory card 8.

  Further, the microcomputer 9 performs image processing using white balance gains Gr2 and Gb2 (Gr2> Gr0, Gb2 <Gb0) such that the hue of the image data stored in the frame memory 3 at the next timing is red. The image processing apparatus 4 is made to perform, and after compression, an image file including the third captured image data is created and recorded in the memory card 8. Through the above operation, a set of three pieces of photographed image data having different colors is recorded in the memory card 8.

  When the microcomputer 9 records an image file including a set of three sets of shot image data each having a different hue on the memory card 8, it can identify that the set of shot image data was shot in the AB shooting mode. In addition, a set of captured image data is associated as a series of image data, and the association can be identified. Further, the microcomputer 9 makes it possible to identify the image parameter changed for each set of photographed image data.

  As a method of enabling identification of the image parameter that is in the AB shooting mode, the associated image, and the changed image parameter, for example, identification data indicating that the image capturing mode data is in the AB shooting mode It is conceivable to store relevant data that makes the association identifiable or parameter data that makes the image parameter identifiable. As a method of storing the related data in each of the image files, it can be considered that the file names of the three related photographed image data are written together as the related data in each image file. Further, it is conceivable that the identification data is also used as a function of the parameter data by changing the identification data depending on the type of the changed image parameter.

  In addition, as described above, the identification data, related data, and parameter data may be stored in each of the image files. However, the identification data, association data, and parameter data are written in a file separate from the image file. Is also possible. As described above, by storing the identification data, the related data, and the parameter data, it is possible to easily identify the AB imaging mode, the association, and the changed image parameter.

  Also, as a method for identifying the image shooting mode, its association and the changed image parameter, the microcomputer 9 works as a file name attaching means, and a file name that can identify them is attached to the created image file. It is also possible to do. A method of attaching such a file name will be described below with reference to FIG. FIG. 2 shows AB shooting in which image processing with different white balance gains is performed in response to a single shooting operation twice after normal shooting, and a set of three shot images of different colors is recorded. The image processing with different edge emphasis coefficients is performed twice, and AB shooting for recording a set of three sets of shot image data having different image outlines is taken once, and normal shooting is taken in order of once. The file names recorded on the memory card 8 when

  As shown in the figure, the first four characters of the file name of the photographed image data photographed normally are “RIMG”. Also, the file name of all captured image data captured by AB shooting that changes the color balance by changing the white balance gain is “W” at the beginning of the file name, and the edge emphasis coefficient is changed to change the edge of the image. The file name of all captured image data captured by AB shooting that changes the first character of the file name is “S”. In this way, by attaching data indicating the image parameter whose value has been changed according to the AB shooting condition to the file name, the image parameter that has been shot in the AB shooting mode and whose value has been changed mutually by the AB shooting mode. Can be made identifiable.

  When the first AB shooting is performed, the second and third characters are “01”, and when the second AB shooting is performed, the second and third characters are “02”. In this way, by attaching different data to each set of photographed image data photographed by AB photography, it is possible to identify the relationship between the set of photographed image data.

  The fourth character indicates the number of the file created in the set of captured image data obtained by AB shooting. That is, if the fourth character is “1”, it indicates that the file is created on the first sheet, “2” indicates that the file is created on the second sheet, and “3” indicates that the file is created on the third sheet.

  As described above, it is possible to easily identify each item only by looking at the file name by attaching to the image file a file name that makes it possible to identify the AB imaging mode, its association, and the changed image parameter. be able to.

Next, the playback operation of the digital camera shown in FIG. 1 will be described.
First, when a reproduction operation is performed, the microcomputer 9 functions as a first reading unit, and reads the captured image data recorded in the memory card 8 into the buffer memory 7 once. Next, the microcomputer 9 controls the data decompression unit 4d in the image processing device 4 to decompress the captured image data that has been read out and write it back to the buffer memory 7 again. The captured image data written back to the buffer memory 7 is read back by the display control unit 4b, displayed on the display device 5, and reproduced.

  When displaying and reproducing on the display device 5, the microcomputer 9 functions as a first identification unit, and identifies whether or not the read photographed image data is photographed in the AB photographing mode. If the image is taken in the AB shooting mode, the microcomputer 9 then functions as the second reading means, and the read shot image data based on the related data stored in the memory card 8 and the image file name. At the same time, other photographed image data constituting a set of three photographed image data is retrieved and read out. Further, the microcomputer 9 serves as a second identification unit, and identifies an image parameter whose value has been changed for each set of read image data.

  Next, the microcomputer 9 controls the display control unit 4b to display a set of photographed image data side by side, and displays the photographed image in the AB photographing mode and the changed image parameter in an identifiable manner. For example, when the white balance gain is changed and the hue is changed as an image parameter, the characters “AB-AWB” are displayed as indicated by reference numeral 60 in FIG.

  As described above, by displaying a set of shot image data obtained by AB shooting side by side, the effect of shooting in the auto bracket shooting mode can be recognized, and it becomes easy to compare which shot image data is necessary. In addition, since the photographer can recognize that the captured image data is recorded in the auto bracket photographing mode by displaying the fact that the captured image has been photographed, and the image parameter changed by the AB photographing so as to be identifiable. Even if reproduction of similar photographed image data continues, it is not accidentally deleted.

  Here, when a print reproduction operation is performed, the microcomputer 9 performs a print reproduction process. This print reproduction process will be described below with reference to the processing procedure of the microcomputer 9 in FIG. First, the microcomputer 9 functions as a first reading unit and a first identification unit, and determines whether or not the photographed image data for which print reproduction is requested is photographed in the AB photographing mode (step S1). . This determination is made, for example, by reading out identification data stored in the memory card 8 or an image file name.

  If it is not photographed image data photographed in the AB photographing mode (N in step S1), the microcomputer 9 controls the image processing unit 4a to detect the feature of the photographed image data requested to be printed and detected. After performing normal image correction processing based on the characteristics (step S2), the captured image data is sent to the print output device 10 and printed out (step S3). As is clear from the above, the image processing unit 4a functions as an image correction unit and a feature detection unit.

  On the other hand, if it is photographed image data photographed in the AB photographing mode (Y in step S1), the microcomputer 9 controls the image processing unit 4a to detect the feature of the photographed image data for which print reproduction is requested. Then, based on the detected feature, after performing the AB image correction process different from the normal image correction process (step S4), the process proceeds to step S3.

Hereinafter, a specific operation of the AB photographing image correction process will be described.
First, the microcomputer 9 functions as a second identification unit, and a set of photographed image data including parameter data stored in the memory card 8 and photographed image data requested to be printed based on the image file name. The changed image parameters are identified for each.

  For example, if the microcomputer 9 determines that the hue has been changed as an image parameter as a result of the image processing performed by changing the white balance gain by the identification, the microcomputer 9 controls the image processing device 4 to perform the image correction processing. Only the processing related to white balance for correcting the hue is not performed, or the correction amount related to white balance is made smaller than the normal correction.

  Similarly, when the contour or brightness is changed as an image parameter, the image correction processing for correcting the contour and the image correction processing for correcting the brightness are not performed, or the correction amount is set to normal. Or make it smaller.

  If the above-described AB photographing image correction processing is performed for each of the photographed image data obtained by AB photographing, for example, for a set of photographed image data whose hue, contour, and brightness are changed, the hue, contour Thus, image correction processing that causes a difference in brightness is not performed. In other words, image correction processing that eliminates the difference in image parameter values that the photographer intentionally changed is not performed, and photographed image data that reflects the photographer's intention to photograph can be printed out. .

Next, the operation of the AB photographing image correction process in another embodiment will be described.
First, the microcomputer 9 functions as a second reading unit, and a set of three images is taken together with related data stored in the memory card 8 and image data for which print reproduction is requested based on the image file name. Other photographed image data constituting the image data is retrieved and read out. Then, the difference between the values of the changed image parameters is extracted for each of the read three sets of captured image data.

  As a method for extracting the difference between the image parameter values, for example, when a set of captured image data captured by AB imaging is recorded in the memory card 8, data indicating the changed image parameter value is stored in advance. If the file name indicating the value of the image parameter is attached or attached, there is a method of reading and extracting the data or the file name.

  On the other hand, if the data is not stored in advance or the file name indicating the value of the image parameter is not attached, the image processing unit 4a extracts it based on the features detected for each set of photographed image data. It is also possible to do. Thereafter, the microcomputer 9 controls the image processing unit 4a to perform image correction processing for a set of photographed image data so that the difference between the extracted image parameter values is maintained.

  As described above, when the image correction process is performed on the read set of captured image data, the photographer can perform the image correction process so that the difference between the image parameter values is maintained. It is possible to perform image correction without erasing the difference in the value of the image parameter that has been changed intentionally, and it is possible to print out the captured image data reflecting the photographer's intention to capture.

  In the above-described embodiment, when the digital still camera records a set of shot image data shot in one AB shooting mode on the memory card 8, one of them is shot in the AB shooting mode. Three sets of image parameters whose values are changed for each set of captured image data are recorded so as to be identifiable. However, it is not necessary to display a set of captured image data side by side, and when performing the above-described image correction processing among the two image correction processes, the microcomputer 9 does not identify the association, It is also possible to make it possible to identify an image parameter that has been shot in the AB shooting mode and whose value has been changed for each of the set of shot image data.

  In addition, when performing the image correction process described later among the two image correction processes, if the difference between the image parameter changed using the image processing apparatus 4 and the value of the image parameter of each other is extracted, It is also conceivable that the digital still camera can identify only that the image was captured and its association without identifying the changed image parameter.

  Furthermore, in this embodiment, the recording medium is the memory card 8, but it may be a built-in memory of a digital still camera.

  Further, although the case where the playback apparatus is in the digital still camera has been described, the playback apparatus may be separated from the digital still camera. In this case, the playback device reads data from the digital still camera when reading from the memory card 8, when the playback device reads from the digital still camera via a wired or wireless connection, and by using the card drive of the playback device. Three forms for reading from the card 8 are conceivable.
