Description

  The present invention relates to a digital still camera, a digital video camera, a camera-equipped mobile phone, a scanner, and other imaging devices that can change the color space of an output image, an imaging method, a recording medium, and a program.

  Conventionally, when a color space of image data obtained by photographing a subject is designated, for example, in a digital still camera in which a color space such as sRGB or AdobeRGB can be selected from the outside, the photographer sets a desired color space before imaging. It was specified for each sheet. In addition, when obtaining image data of a plurality of color spaces, the setting is changed to a desired color space every time one image is shot, and shooting is performed a plurality of times.

  In addition, when it is desired to change the color space of image data captured by a digital still camera after imaging, color space conversion processing is performed on the captured data using PC application software such as photo retouching software. Similarly, the image data after shooting is also changed in color by PC application software (see, for example, Patent Document 1).

In addition, by pressing a single release button on a digital camera, auto-bracketing shooting that sets a white balance correction value and exposure value before shooting and obtains a plurality of image data in which the setting values are shifted in stages. Is known (for example, see Patent Document 1).
JP 06-268856

  However, in the conventional digital still camera, the photographer sets a color space in advance for each image of one screen, so if the photographer wants to change the color space after shooting, change it with a PC application. It took time and effort to do it.

  Further, in the PC application software, when a subject with high saturation is captured in a narrow color space such as sRGB as shown in FIG. 9 and the color is saturated, the PC application software is wider than the sRGB space (for example, AdobeRGB). ) Colors that were saturated even after conversion to color space could not be expressed correctly. Therefore, when an image in two or more different color spaces is required, the photographer always takes an image in a wide color space, and later changes to a necessary color space with PC application software, or pre-shoots a digital still before shooting. It was necessary to change the setting in the color space selection menu of the camera and perform imaging for each color space.

  As shown in FIG. 9, when changing the hue of image data defined in the sRGB space, for example, by PC application software, the hue can be changed from P0 to P2 in the same color space. However, since it was impossible to map the color P0 in the sRGB space to a color outside the defined color space such that the color P0 was changed to P1, the color reproducibility was lowered and a problem occurred in the color adjustment.

The imaging apparatus of the present invention includes an imaging instruction means for instructing imaging by a user operation,
Image input means for inputting image data;
Color space setting means for setting a plurality of different color space information;
In response to a single imaging instruction from the imaging instruction unit, image data is input by the image input unit, and the input image data and a plurality of different color space information set by the setting unit are automatically associated with each other. Storage means for storing

Display means for displaying the image data subjected to image processing by the image processing means,
The image data is displayed on the means for each color space based on the identification information of the image data.

  According to the present invention, since it is possible to perform color space bracket imaging that automatically stores images of different color spaces in response to a single imaging instruction operation, it is possible to easily obtain images of a plurality of different color spaces. I can do it. In addition, since an image in the color space intended by the photographer can be selected from a plurality of images in different color spaces, it is possible to avoid image reprocessing according to the intended use and re-imaging.

  Next, six different embodiments of the operation of the digital still camera configured as described above will be described. Note that the configuration described above is common to the first to sixth embodiments, and is therefore omitted.

<First Embodiment>
First, as a first embodiment, two image input (imaging) operations are automatically performed in response to one operation of the imaging instruction means, and images of different color spaces (sRGB and AdobeRGB) are formed for each imaging. In the color space bracket imaging mode in which images are output in order, an operation for outputting an image to the external storage device 111 by dividing a directory or a folder for each color space will be described below. In the present embodiment, a case in which an image of two color spaces is output will be described. However, the number of color spaces may be two or more, and is not limited to sRGB and AdobeRGB.

  FIG. 3 is a flowchart showing an operation example of the digital still camera 100 according to the first embodiment of the present invention. Hereinafter, description will be given with reference to this flowchart.

  First, before image capturing, the user selects and sets which color space image is to be output at the time of color space bracket imaging. Here, two or more color spaces are selected. In the first embodiment, it is assumed that two color spaces of sRGB and AdobeRGB are selected. In this case, image processing for the selected color space is performed, and images are output in order for each imaging. For example, the first frame is output in sRGB and the second frame is output in AdobeRGB, which is one set. Similarly, when there are three or more selected color spaces, the number of imaging frames corresponding to the number of the color spaces is set as one set, and images are picked up by automatically changing the color space repeatedly. When setting one color space, two or more color spaces close to the set color space may be automatically set. For example, when the sRGB space is set, the other is bracket shooting with different color space areas of the shot image so that an AdobeRGB space larger than the sRGB space shown in FIG. 9 is automatically set. Can be done.

  When the user presses the release button for instructing imaging after setting the above conditions, imaging of the first frame is started and imaging data is input from the input device 101. (Step s301) Specifically, the image is captured by photoelectrically converting a subject image formed through a lens by an image pickup device such as a CCD, and the electric signal is converted into digital image data through an A / D converter. Is output.

  Next, the microcomputer 112 instructs the image processing apparatus 103 to perform development processing using image processing parameters (color conversion coefficients) for the sRGB color space out of the sRGB and AdobeRGB color spaces selected by the color space selection unit. (Step s302).

  In the image processing apparatus, after color interpolation and white balance correction are performed, color conversion processing is performed using color conversion coefficients for sRGB in accordance with support from the microcomputer. Subsequently, after performing gamma correction and edge enhancement processing, the image is compressed to JPEG or the like (step s303).

  The compressed image file is output to the buffer memory 110 after adding sRGB color space information and bracket shooting number information to the header of the file (step s304). Here, since it is the first image of bracket shooting, 1 is input as information. When the bracket photography is not performed, 0 is input to this information.

  In step s305, if the “sRGB” directory or folder does not exist in the external storage device, a directory or folder named “sRGB” is created (step s306), and the sRGB image is recorded therein (step s306). Step s307).

  In step s305, if the “sRGB” directory or folder already exists in the external storage device, the sRGB image is recorded in the “sRGB” directory or folder (step s307).

  Here, the name of the directory or folder is “sRGB”, but this name is not limited thereto. However, file names are assigned so that file names are not duplicated within a directory or folder in the same color space.

  Up to this point, sRGB recording processing has been performed among the two color spaces, sRGB and AdobeRGB, which have been preset as the color space for bracket imaging. The processing from step s301 to step s307 is repeated by the number of set color spaces (step s308).

  Here, since the second frame is set in AdobeRGB, the process will be described in the same manner.

  Subsequently, imaging of the second frame is performed, and imaging data is input again from the input device 101 (step s301).

  Next, the microcomputer 112 instructs the image processing apparatus 103 to perform development processing with the image processing parameters (color conversion coefficients) for the AdobeRGB color space out of the sRGB and AdobeRGB color spaces selected by the color space selection unit. (Step s302).

  In the image processing apparatus, after performing color interpolation and white balance correction, color conversion processing is performed using color conversion coefficients for AdobeRGB in accordance with support from the microcomputer. Subsequently, after performing gamma correction and edge enhancement processing, the image is compressed to JPEG or the like (step s303).

  The compressed image file is output to the buffer memory 110 after adding the AdobeRGB color space information and the bracket shooting number information to the header of the file (step s304). Here, since it is the second image of bracket shooting, 2 is input as information.

  If the “adobeRGB” directory or folder does not exist in the external storage device in step s305, a directory or folder named “adobeRGB” is created (step s306), and the AdobeRGB image is recorded therein (step s306). Step s307).

  If an “adobeRGB” directory or folder already exists in the external storage device in step s305, the AdobeRGB image is recorded in the “adobeRGB” directory or folder (step s307).

  Here, the name of the directory or folder is “adobeRGB”, but this name is not limited thereto. However, file names are assigned so that file names are not duplicated within a directory or folder in the same color space.

  Up to this point, images of two color spaces, sRGB and AdobeRGB, previously set as the color space for bracket imaging have been output. One set of imaging of sRGB and AdobeRGB is completed as bracket imaging of the color space.

  That is, in bracket imaging of two color spaces of sRGB and AdobeRGB, the two color spaces are set as one set of brackets, and two frames are automatically captured with one shutter release, and one set of imaging is completed. Similarly, also in the case of bracket imaging in three or more color spaces, one set of imaging is completed when the number of frames corresponding to the number of color spaces is imaged.

  As described above, according to the first embodiment, since the output image file is stored in a different directory or folder for each color space, subsequent image management can be easily performed.

<Second Embodiment>
As a second embodiment, color space bracket imaging that performs two image input (imaging) operations in response to one imaging instruction, and sequentially outputs images of different color spaces (sRGB and AdobeRGB) for each imaging. The operation of changing the file name of each image in each color space and outputting the image to the external storage device 111 in the mode will be described below.

  FIG. 4 is a flowchart showing an operation example of the digital still camera 100 according to the second embodiment of the present invention. Hereinafter, description will be given with reference to this flowchart.

  First, in steps s401 to s404, similarly to steps s301 to s304 in FIG. 3, control is performed so that sRGB color space information is first obtained, and the sRGB color space information and bracket shooting number information are loaded and output to the buffer memory 110. To do. Here, since it is the first image of bracket shooting, 1 is input as information. When the bracket photography is not performed, 0 is input to this information.

  In step s405, the file name of the sRGB image is “s0000.jpg” before the sRGB image recorded in the buffer memory 110 is recorded in the external storage device 111. (Step s405) Although the file name is “s” in this embodiment, the file name is not limited to this as long as the name is different for each color space. Finally, this image is recorded in the external storage device 111 (step s406).

  In the processing up to this point, sRGB processing has been performed out of the two color spaces of sRGB and AdobeRGB which have been preset as the color space for bracket imaging. The processing from step s401 to step 406 is repeated for the set number of color spaces. (Step s407) Next, the second frame will be described in the same manner.

  Subsequently, imaging of the second frame is performed, and imaging data is input again from the input device 101 (step s401).

  Next, the microcomputer 112 instructs the image processing apparatus 103 to perform development processing with the image processing parameters (color conversion coefficients) for the AdobeRGB color space out of the sRGB and AdobeRGB color spaces selected by the color space selection unit. (Step s402) Color conversion processing is performed using color conversion coefficients for AdobeRGB, and the compressed image file is added to AdobeRGB color space information and bracket shooting number information in the header portion of the file, and then buffered. 110 (step s404). Here, since it is the second image of bracket shooting, 2 is input as information.

  In step s405, before the AdobeRGB image recorded in the buffer memory 110 is recorded in the external storage device 111, the file name of the AdobeRGB image is “adobe0000.jpg”.

  In this embodiment, the file name uses “adobe” and the name representing the color space itself, but the file name is not limited to this as long as the name is different for each color space. Finally, this image is recorded in the external storage device 111 (step s406).

  In the file names (s0000.jpg and Adobe0000.jpg), 0000 indicates a file number, and the count is incremented by 1 each time data for each color space is stored in the external storage device. In this embodiment, the count number is individually managed for each color space in the microcomputer 112, but the count number may be managed without distinguishing the color space. In this case, in this embodiment, files “s0000.jpg” and “adobe0001.jpg” are output.

  Up to this point, images of two color spaces, sRGB and AdobeRGB, previously set as the color space for bracket imaging have been output. As in the first embodiment, one set of imaging of sRGB and AdobeRGB is completed as bracket imaging of the color space.

  Since the output image file is added with a different file name for each color space or a file name that can identify the color space, the subsequent image management can be easily performed (however, here, for example, “IMG — 0001”). In the case of a file “.JPG”, “IMG_” is a file name and “0001” is a file number).

<Third Embodiment>
As a third embodiment, in the color space bracket imaging mode in which images of two color spaces (sRGB and AdobeRGB) are sequentially output for each imaging instruction, the extension of the image file is changed for each color space. The operation output to the external storage device 111 will be described below.

  FIG. 5 is a flowchart showing an operation example of the digital still camera 100 according to the third embodiment of the present invention. Hereinafter, description will be given with reference to this flowchart.

  First, for example, the first image is output in sRGB, the second image is output in AdobeRGB, and this is set as one set, which is the same as in the first and second embodiments. Steps s501 to s504 Is the same as steps s301 to s304, and a description thereof will be omitted. In step s 505, the file name of the sRGB image is “IMG — 0000.sjpg” before the sRGB image recorded in the buffer memory 110 is recorded in the external storage device 111. (Step s505) Although the extension of the file is “sjpg” in this embodiment, it is not limited to this as long as the name is different for each color space. Finally, this image is recorded in the external storage device 111 (step s506).

  Subsequently, the second frame is imaged, color conversion processing is performed using the color conversion coefficients for AdobeRGB, and the color space information of AdobeRGB is added to the header portion of the file, which is then output to the buffer memory 110 (step s504). ).

  In step s505, before the AdobeRGB image recorded in the buffer memory 110 is recorded in the external storage device 111, the filename of the AdobeRGB image is “IMG — 0000.adobejpg”.

  Although the file name is “adobe” in the present embodiment, the file name is not limited to this as long as the name is different for each color space. Finally, this image is recorded in the external storage device 111 (step s506).

  In the file names (IMG_0000.sjpg and IMG_0000.adobejpg), 0000 indicates a file number, and the count is incremented by 1 each time data for each color space is stored in the external storage device. In this embodiment, the count number is individually managed for each color space in the microcomputer 112, but the count number may be managed without distinguishing the color space. In that case, in the case of the present embodiment, files “IMG — 0000.sjpg” and “IMG — 0001.adobejpg” are output.

  In this manner, since different extensions are added to the output image file for each color space, subsequent image management can be easily performed.

  In the first to third embodiments, when the user presses the release button once, imaging data is automatically input at a predetermined pitch by the number of color spaces set by the user, and image processing in different color spaces is performed. Was done. Therefore, by using image processing parameters for different color spaces for each imaging, a plurality of images of different color spaces are output.

  In the fourth to sixth embodiments, when the user presses the release button once, the imaging data is input only once, and thereafter, the same imaging data is subjected to image processing for different color spaces, and a plurality of An embodiment for outputting images of different color spaces will be described.

<Fourth Embodiment>
First, an operation of outputting images of two color spaces (sRGB and AdobeRGB) to the external storage device 111 by dividing a directory or a folder for each color space for one imaging will be described below. In the present embodiment, a case where an image of two color spaces is output will be described. However, the number of color spaces may be two or more, and is not limited to sRGB and AdobeRGB.

  FIG. 6 is a flowchart showing an operation example of the digital still camera 100 according to the fourth embodiment of the present invention. Hereinafter, description will be given with reference to this flowchart.

  First, before imaging, the user selects which color space to output an image. (Step s601) Here, a plurality of color spaces are set. When a plurality of settings are made, images of a plurality of color spaces selected for each imaging data are output. In the fourth embodiment, it is assumed that two color spaces of sRGB and AdobeRGB are selected. However, since the setting of the color space once set is held, it is not necessary to set it every time imaging is performed.

  After the above condition setting, when a user presses a release button (not shown) for instructing imaging, imaging is started, and imaging data is input from the input device 101. (Step s602) Specifically, the image is captured by subjecting the subject image formed through the lens to photoelectric conversion by an image pickup device such as a CCD, and the electric signal through the A / D converter as digital image data in the frame memory 102. Is output.

  Next, the microcomputer 112 instructs the image processing apparatus 103 to perform development processing with the image processing parameters (color conversion coefficients) for the sRGB color space selected by the color space selecting means (step s603).

  In the image processing apparatus, after performing color interpolation and white balance correction, color conversion processing is performed using sRGB color conversion coefficients in accordance with instructions from the microcomputer. Subsequently, after performing gamma correction and edge enhancement processing, the image is compressed to JPEG or the like (step s604).

  The compressed image file is output to the buffer memory 110 after adding sRGB color space information to the header of the file (step s605).

  Next, it is detected whether all the images in the color space selected in step s601 have been output. (Step s606) Since only sRGB is output at this stage and the other selected color space AdobeRGB is not output, the process returns to Step s603, and the microcomputer 112 performs development processing with the image processing parameters (color conversion coefficients) for AdobeRGB. The image processing apparatus 103 is instructed to perform the process. (Step s603) The image processing apparatus performs color interpolation and white balance correction, and then performs color conversion processing using color conversion coefficients for AdobeRGB in accordance with instructions from the microcomputer. Subsequently, after performing gamma correction and edge enhancement processing, the image is compressed to JPEG or the like (step s604).

  The compressed image file is output to the buffer memory 110 after adding AdobeRGB color space information to the header of the file (step s605).

  At this time, since the images of the two selected color spaces are output in step s606, the process proceeds to step s607.

  At present, the buffer memory 110 temporarily stores images of two color spaces, sRGB and AdobeRGB. Here, in order to record the sRGB image in the buffer memory 110 in the external storage device 111, it is checked whether the “sRGB” directory or folder exists in the external storage device 111 (step s607).

  In step s307, if the “sRGB” directory or folder does not exist in the external storage device, a directory or folder named “sRGB” is created (step s608), and the sRGB image is recorded therein (step s608). Step s609).

  In step s607, if the “sRGB” directory or folder already exists in the external storage device, the sRGB image is recorded in the “sRGB” directory or folder (step s609).

  Here, the name of the directory or folder is “sRGB”, but this name is not limited thereto. However, file names should not be duplicated for each color space.

  Next, it is detected whether or not all color space images in the buffer memory 110 have been recorded in the external storage device 611 in step s610. If not, the process returns to step s607 (step s609).

  Although the sRGB image is recorded at this stage, but the AdobeRGB image is not recorded, the process returns to step s607. If the “adobeRGB” directory or folder does not exist in the external storage device in step s607, a directory or folder named “adobeRGB” is created (step s608), and the image is recorded therein (step s609). ).

  In step s607, if the “adobeRGB” directory or folder already exists in the external storage device, the image is recorded in the “adobeRGB” directory or folder.

  Here, the name of the directory or folder is “adobeRGB”, but this name is not limited thereto. However, file names should not be duplicated for each color space.

  Next, it is detected again whether or not all the images in the buffer memory 110 have been recorded in the external storage device 111 in step s610. At this stage, since the selected two images of sRGB and AdobeRGB are already stored in the external storage device 111, the processing is completed.

  As described above, according to the fourth embodiment, since the output image file is stored in a different directory or folder for each color space, subsequent image management can be easily performed.

<Fifth Embodiment>
Next, the operation of changing the file name for each color space and outputting the image in two color spaces (sRGB and AdobeRGB) to the external storage device 111 for one imaging will be described below.

  FIG. 7 is a flowchart showing an operation example of the digital still camera 100 according to the fifth embodiment of the present invention. Hereinafter, description will be given with reference to this flowchart. Since s701 to s706 are the same as s601 to s606, description thereof is omitted.

  When the images of the two color spaces selected in step s706 are output, the process proceeds to step s707.

  Here, before the sRGB image recorded in the buffer memory 110 is recorded in the external storage device 111, the file name of the sRGB image is “s0000.jpg”. (Step 7407) Although the file name is “s” in this embodiment, the file name is not limited to this as long as the name is different for each color space.

  In s708, it is determined whether or not all images in the selected color space have been recorded in the external storage device 111. At this stage, only sRGB is recorded, and AdobeRGB is not recorded. Therefore, the process returns to step s707, the file name of the sRGB image recorded in the buffer memory 110 is “adobe0000.jpg”, and the image is stored in the external storage device. 111. Although the file name is “adobe” in the present embodiment, the name is not limited to this as long as the name is different for each color space. However, by adding the name of the color space, the image name can be seen only by looking at the file name. The color space can be discriminated.

  In the file names (s0000.jpg and Adobe0000.jpg), 0000 indicates a file number, and the count is incremented by 1 each time data for each color space is stored in the external storage device. In this embodiment, the count number is individually managed for each color space in the microcomputer 112, but the count number may be managed without distinguishing the color space. In this case, in this embodiment, files “s0000.jpg” and “adobe0001.jpg” are output.

  Since all the color space images selected above have been output, the processing ends (step s708).

  Since a different file name for each color space is added to the output image file in this way, subsequent image management can be easily performed.

<Sixth Embodiment>
Next, an operation of outputting images of two color spaces (sRGB and AdobeRGB) to the external storage device 111 for each color space while changing the extension for each color space will be described below.

  FIG. 8 is a flowchart showing an operation example of the digital still camera 100 according to the sixth embodiment of the present invention. Since s801 to s806 are the same as s601 to s606, description thereof is omitted.

  When the images of the two color spaces selected in step s806 are output, the process proceeds to step s807.

  The extension of the sRGB image recorded in the buffer memory 110 is “IMG — 0000.sjpg”. (Step s807) Although the file name is “sjpg” in this embodiment, the file name is not limited to this as long as the extension is different for each color space.

  In s808, it is determined whether or not all the images in the selected color space have been recorded in the external storage device 111. At this stage, only sRGB is recorded, and AdobeRGB is not recorded. Therefore, the process returns to step s807, and the file name of the sRGB image recorded in the buffer memory 110 is “IMG — 0000.adobejpg”. In this embodiment, the extension uses the extension name indicating the color space as “adobejpg”, but the extension is not limited to this as long as the extension is different for each color space.

  In the file names (IMG_0000.sjpg and IMG_0000.adobejpg), 0000 indicates a file number, and the count is incremented by 1 each time data for each color space is stored in the external storage device. In this embodiment, the count number is individually managed for each color space in the microcomputer 112, but the count number may be managed without distinguishing the color space. In that case, in the case of the present embodiment, files “IMG — 0000.sjpg” and “IMG — 0001.adobejpg” are output.

  Since all the color space images selected above have been output, the processing ends (step s808).

  In this manner, since different extensions are added to the output image file for each color space, subsequent image management can be easily performed.

  In the above embodiment, a description has been given of a form related to a digital camera having only one external storage device 11 as a recording means. For example, a digital camera having two slots of a CF card (registered trademark) and an SD (registered trademark) card. If it is a multi-slot digital camera having one or more recording means like a camera, the above embodiment can be further applied to record an image on a different recording means for each color space, or select a recording means for each color space. Then, the image may be recorded. For example, when an image file of CMYK data is recorded on a CF card (registered trademark) and an image file of sRGB data is recorded on an SD (registered trademark) card, printing is performed with a printer that can directly insert a memory card. Only a CF card (registered trademark) in which data is stored may be used, and work efficiency can be improved.

  In the above embodiment, two different color spaces, sRGB and AdobeRGB, have been described. However, the color space is not limited to this, for example, CMYK for printing, L * a * b *, and the like. Various things are possible. The setting of the plurality of color spaces may be selected by the user from among the image processing for each of the plurality of color spaces stored at the time of factory shipment, or the image processing of the plurality of color spaces may be performed at the time of factory shipment. Including those that have been set.

  In the embodiment, a description has been given of a mode in which image processing corresponding to each color space is processed in the digital camera and then recorded in the external storage device for a plurality of color spaces set by the user. The color space information set by the user in the header area is added as identification information for identifying the color space, recorded in an external storage device including a removable storage medium, and each color of the image data is referred to while referring to the header information during reproduction. You may make it perform the image process corresponding to space. The header area may be added for each image data, or identification information that can identify a plurality of different color spaces may be recorded in the header area of one original image data.

  Further, during reproduction, each color space information recorded in the header information added to the image is displayed on the liquid crystal monitor 113 together with the image data subjected to the image processing for the color space as shown in FIG. Thus, it is possible to confirm in which color space the processed image is represented. If the extension includes information specifying the color space, the color space may be determined from the extension and displayed on the liquid crystal monitor during reproduction.

  Further, when playing back or displaying an image on a PC application, the bracketed image is detected from each color space information and bracket shooting number information recorded in the header information added to the image, as shown in FIG. As described above, only the image taken with the color space bracket at the same time may be displayed on the monitor on the image pickup apparatus together with the image and the color space information recorded in the header information or the file name so as to display multiple images. In this way, the user can easily compare and confirm images of different color spaces in the same scene after shooting.

  Further, when displaying a bracket image, a marking or icon for an image that is bracketed in a color space such as “B” in FIG. 10, so that it can be seen at a glance that the image is a bracketed image. May be added. At this time, the determination as to whether or not the image has been taken with brackets is performed by, for example, looking at bracket shooting number information that has been added to the image in advance, Mark the display.

  The color space information of the header area or the extension can be used not only for reproduction but also for printing processing in the printing apparatus and matching processing for other devices.

  It is also possible to search for an image in a desired color space from the header information of the photographed image in accordance with the color space of the output destination device and output it in a batch. For example, only the image of the CMYK color space can be retrieved from the header information added to the image and output to the printer at the same time during printing. By doing so, it is possible to shorten and simplify the printing process. Similarly, it is also possible to search only images in the sRGB space for monitoring and output them collectively to the monitor for multi-image display.
