  FIG. 1 is a block diagram illustrating an example of a configuration of an image processing system according to an embodiment. The image processing system of the present embodiment includes an electronic camera 1 as an imaging device and a computer 2 as an image processing device.

  A configuration of the electronic camera 1 of the present embodiment will be described. The electronic camera 1 includes an imaging optical system 11, an imaging device 12, a DFE 13, a CPU 14, a first memory 15, a second memory 16, a media I / F 17, a communication I / F 18, a monitor 19, and an operation unit 20 that receives user operations. Have. Here, the DFE 13, the first memory 15, the second memory 16, the media I / F 17, the communication I / F 18, the monitor 19, and the operation unit 20 are each connected to the CPU 14.

  Note that the electronic camera 1 of the present embodiment has three recording modes from the first recording mode to the third recording mode as sub-modes of the imaging mode. The electronic camera 1 in the first recording mode records a raw color image (raw image). The electronic camera 1 in the second recording mode records image data obtained by performing electronic development processing (digital development processing) on the raw image as a developed image. The electronic camera 1 in the third recording mode records both the raw image and the developed image.

  Furthermore, the electronic camera 1 of the present embodiment has a priority setting mode for setting priorities regarding use of image data for Raw images and developed images as another sub-mode of the imaging mode. That is, the image data set with the priority is preferentially selected over the other image data, and the added image information is displayed on the monitor 19 or the computer 2 performs image processing.

  The image pickup device 12 is a device that picks up an image of an object formed by a light beam that has passed through the image pickup optical system 11. The output of the image sensor 12 is connected to the DFE 13. Note that the image sensor 12 of the present embodiment may be a progressive scanning solid-state image sensor (CCD or the like) or an XY address type solid-state image sensor (CMOS or the like).

  A plurality of light receiving elements are arranged in a matrix on the light receiving surface of the imaging element 12. In addition, red (R), green (G), and blue (B) color filters are arranged in each light receiving element of the imaging element 12 according to a known Bayer array. Therefore, each light receiving element of the imaging element 12 outputs an image signal corresponding to each color by color separation in the color filter. Thereby, the image sensor 12 can acquire a color image at the time of imaging.

  The DFE 13 is a digital front-end circuit that performs signal processing such as A / D conversion of image signals input from the image sensor 12 and correction of defective pixels. The DFE 13 forms an imaging unit together with the imaging device 12 in this embodiment, and outputs an image signal input from the imaging device 12 to the CPU 14 as raw image data. Here, the RAW image is digital image data in which the relationship between the output signal value and the amount of incident light is linear. This raw image may be one that has been subjected to defective pixel correction processing. The raw image may be a mosaic image having a Bayer arrangement structure in a state before color interpolation, or may be a color image after color interpolation processing is performed.

  The CPU 14 is a processor that comprehensively controls each unit of the electronic camera 1. For example, the CPU 14 executes a known autofocus (AF) control by contrast detection, a known automatic exposure (AE) calculation, and the like based on the output of the image sensor 12. Further, the CPU 14 operates as an image processing unit 21, an image information generation unit 22, an image file generation unit 23, a priority information change unit 24, a mode setting unit 25, a recording control unit 26, and a display control unit 27 by executing the program. To do.

  The image processing unit 21 performs digital development processing on the raw image data to generate developed image data. Here, the digital development processing is image processing for converting a Raw image into an image corresponding to a photograph. As an example, the digital development processing includes interpolation processing, white balance processing, gradation conversion processing, noise removal processing, contour enhancement processing, color conversion processing (such as calculation in a color conversion matrix), and gamma conversion. The developed image data is generated in a known format such as the Jpeg format or the TIFF format.

  The image information generation unit 22 generates image information regarding each of the raw image and the developed image. The image information includes imaging conditions such as the date and time when the raw image was captured, the shutter speed, the exposure time, and the focal length. The image information of the present embodiment includes at least one piece of information on the histogram, the image size, and the color space of each of the raw image and the developed image.

  Furthermore, the image information generation unit 22 generates priority information related to the use of image data in order to preferentially select either a raw image or a developed image according to the setting of the priority setting mode. The image information generation unit 22 according to the present embodiment generates priority information “true” for an image for which priority is set, and priority information “false” for an image for which no priority is set. To do. The priority is “true” and “false”, but may be specified by a numerical value such as “1” or “0”.

  The image file generation unit 23 generates an image file by adding the image information generated by the image information generation unit 22 to the raw image and the developed image according to the setting of the recording mode. For example, the image file of the developed image is generated in a format compliant with the Exif (Exchangeable image file format for digital still cameras) standard or the TIFF / EP standard.

  Further, the image file generation unit 23 adds the priority information generated by the image information generation unit 22 to at least one of the raw image and the developed image. Note that the image file generation unit 23 of the present embodiment adds priority information to both the raw image and the developed image.

  The priority information changing unit 24 changes the priority information added to each image file from “true” to “false”, or from “false” to “true” in accordance with a change instruction from the user.

  The mode setting unit 25 sets or changes the mode upon receiving a mode setting or change instruction such as a recording mode and priority setting mode from the operation unit 20. That is, the mode setting unit 25 has a function of a priority setting unit.

  The display control unit 27 performs control to display the image information of the raw image or the developed image on the monitor 19 based on the priority information generated by the image information generation unit 22.

  The first memory 15 is a volatile buffer memory that temporarily stores image data before and after image processing.

  The second memory 16 is a non-volatile flash memory that stores various programs executed by the CPU 14. The second memory 16 may have a storage area for storing image files and the like.

  A non-volatile storage medium 17a can be detachably connected to the media I / F 17. Then, the media I / F 17 executes data writing / reading with respect to the storage medium 17a. The storage medium 17a is composed of a hard disk, a memory card incorporating a semiconductor memory, or the like. In FIG. 1, a memory card is illustrated as an example of the storage medium 17a.

  The communication I / F 18 controls data transmission / reception with an external apparatus (such as an image processing apparatus) connected via a known wired or wireless communication line in accordance with a predetermined communication standard. The monitor 19 displays a captured image and the like under the control of the CPU 14.

  The operation unit 20 receives, for example, a recording mode switching input, a still image (main image) imaging instruction accompanied by recording in the storage medium 17a, and the like from the user. For the operation unit 20, a touch panel or the like disposed on the front surface of the monitor 19 can be appropriately selected and used.

  Next, the configuration of the computer 2 that configures the image processing system according to the present embodiment and performs image processing on the image captured by the electronic camera 1 will be described. The computer 2 is a personal computer in which an image processing program is installed, and includes a data reading unit 31, a communication unit 32, a storage device 33, a CPU 34, a memory 35, an input / output I / F 36, and a bus 37. The data reading unit 31, the communication unit 32, the storage device 33, the CPU 34, the memory 35, and the input / output I / F 36 are connected to each other via a bus 37. Furthermore, an input device 38 (keyboard, pointing device, etc.) and a monitor 39 are connected to the computer 2 via an input / output I / F 36. The input / output I / F 36 accepts various inputs from the input device 38 and outputs display data to the monitor 39.

  The data reading unit 31 is used when reading an image file generated by the electronic camera 1 or an image processing program from the outside. For example, the data reading unit 31 includes a reading device (such as a reading device for an optical disk, a magnetic disk, a magneto-optical disk, or a memory card) that acquires data from a removable storage medium.

  The communication unit 32 controls data transmission / reception with an external device (such as the electronic camera 1) connected via a known wired or wireless communication line in accordance with a predetermined communication standard.

  The storage device 33 stores the image processing program and various data necessary for executing the program. The storage device 33 can also store image file data acquired from the data reading unit 31 or the communication unit 32. The storage device 33 is configured by a hard disk, a nonvolatile semiconductor memory, or the like.

  The CPU 34 is a processor that comprehensively controls the operation of each unit of the image processing apparatus 2. The CPU 34 performs various processes on the image captured by the electronic camera 1 by executing the image processing program. Furthermore, the CPU 34 also operates as a display control unit that displays the image information of the raw image or the developed image on the monitor 39 based on the priority information. An example of the operation of the image processing program by the computer 2 will be described later.

  The memory 35 temporarily stores the calculation result of the image processing program. The memory 35 is composed of, for example, a volatile SDRAM.

Next, specific operations of the image processing system according to the present embodiment shown in FIG. 1 will be described. 1) One operation example of the electronic camera 1 2) Other operation example of the electronic camera 1 3) Computer 2 The three cases of the operation example are performed.
1) Example of Operation of Electronic Camera 1 An example of operation of the electronic camera 1 in the present embodiment will be described with reference to the flowchart of FIG.

  Step S101: The mode setting unit 25 of the CPU 14 prepares before receiving an instruction to capture a main image from the user (for example, full pressing operation of a release button included in the operation unit 20). Any mode setting instruction is received from the operation unit 20. In the operation example of the present embodiment, it is assumed that the mode setting unit 25 sets the third recording mode.

  Step S102: As another preparation before capturing the main image, the mode setting unit 25 converts one of the raw image generated by capturing the main image and the developed image into the subsequent image processing and image information. In display or the like, the operation unit 20 receives a setting instruction of a priority setting mode for selecting preferentially. In the present embodiment, it is assumed that the mode setting unit 25 sets priority for preferentially selecting a Raw image.

  Here, it is assumed that the developed image in the present embodiment is a Jpeg image compressed in the Jpeg format. Further, when the first recording mode is set in step S101, the mode setting unit 25 may automatically set the priority of the RAW image and omit the operation in step S102. Similarly, when the second recording mode is set, the mode setting unit 25 may automatically set the priority of the Jpeg image and omit the operation in step S102.

  Step S103: The CPU 14 drives the image sensor 12 to capture the main image in accordance with an instruction to capture the main image from the user. An image signal output from the image sensor 12 passes through the DFE 13 in a pipeline manner and is input to the CPU 14. The raw image data is buffered in the first memory 15 under the control of the CPU 14. In this embodiment, the CPU 14 holds the raw image before the interpolation process, the white balance adjustment, and the like in the first memory 15 as the first image to be recorded in the storage medium 17a.

  The image information generation unit 22 analyzes the raw image together with the shooting conditions (exposure time, aperture value, etc.) of the raw image that is the first image data, the image file name, and the like, and the histogram of the raw image, the image size, and the color space. Image information including at least one of the following is generated. The CPU 14 holds the image information of the Raw image in the first memory 15.

  Step S104: The image processing unit 21 performs digital development processing on the Raw image to generate a Jpeg image (second image data) that is an RGB developed image. The data of the Jpeg image is temporarily stored in the first memory 15 under the control of the CPU 14.

  The image information generation unit 22 analyzes the Jpeg image that is the second image data, and generates image information including at least one of a histogram, an image size, and a color space of the Jpeg image. The image information of the Jpeg image includes information such as the shooting condition of the Raw image and the image file name. The CPU 14 holds the image information of the Jpeg image in the first memory 15.

  Step S105: The image file generation unit 23 uses the image information of the JPEG image generated by the image information generation unit 22 in step S104 as metadata (or header data) in association with the data of the Jpeg image. A file is generated (FIG. 3).

  Step S106: In step S103, the image file generation unit 23 uses the image information of the Raw image generated by the image information generation unit 22 as metadata, and generates an image file of the Raw image in association with the Raw image data ( FIG. 3).

  Step S107: The image information generation unit 22 generates priority information of a JPEG image based on the setting of the priority setting mode in step S102. The image file generation unit 23 records the generated priority information in a predetermined area in the metadata of the image file of the Jpeg image. In the present embodiment, since the mode setting that preferentially selects the RAW image is made in step S102, the image file generation unit 23, as shown in FIG. 3, performs the above process in the metadata of the image file of the Jpeg image. Priority information “false” is added to a predetermined area.

  Step S108: The image information generation unit 22 generates the priority information of the Raw image based on the setting of the priority setting mode in Step S102. The image file generation unit 23 records the generated priority information in a predetermined area in the metadata of the raw image file. In the present embodiment, since the mode setting that preferentially selects the RAW image is made in step S102, as shown in FIG. 3, the image file generation unit 23 performs the above process in the metadata of the image data of the RAW image. Priority information “true” is added to a predetermined area.

  Step S109: The image information generation unit 22 calculates a hash value of the RAW image by using a known hash algorithm (for example, MD5, SHA1, etc.), and generates hash value information. The image file generation unit 23 adds the hash value information to predetermined areas in the metadata of the image files of the Raw image and the Jpeg image (FIG. 3). By recording this hash value information in the metadata of each image file, for example, consider a case where a plurality of RAW images and JPEG images are read into the computer 2 to be described later, and the file name of one JPEG image is changed. . In such a case, the computer 2 compares the hash value information of the metadata added to one Jpeg image and each Raw image based on the image processing program to be executed. Thereby, the computer 2 can easily determine from which Raw image one Jpeg image is generated.

Step S110: The recording control unit 26 records the image file of the raw image and the jpeg image on the storage medium 17a. The electronic camera 1 ends the image capturing operation for the main image.
2) Another Operation Example of Electronic Camera 1 Next, as another operation example of the electronic camera 1 in the present embodiment with reference to the flowchart of FIG. 4, a Raw image and a Jpeg image in Step S107 and Step S108 described above. The operation of changing the priority information of the metadata added to the will be described. In the operation example of FIG. 4, it is assumed that the electronic camera 1 is set to the third recording mode and the priority setting mode for preferentially selecting the Raw image, and has performed a plurality of main image capturing operations in advance. Therefore, it is assumed that the electronic camera 1 records a plurality of raw images and image files of jpeg images on the storage medium 17a.

  Step S201: The CPU 14 determines whether or not a priority information change instruction from the user has been received from the operation unit 20. When the priority information change instruction is received, the CPU 14 proceeds to step S202 (YES side). When the priority information change instruction is not received (NO side), the CPU 14 ends the priority information change operation.

  Step S202: The CPU 14 displays on the monitor 19 whether or not the priorities of all the Raw images and JPEG images are to be changed collectively. For example, the CPU 14 displays “Yes” and “No” buttons on the monitor 19. When the CPU 14 receives a “Yes” button signal from the user via a touch panel (not shown) arranged on the front surface of the monitor 19 and constituting the operation unit 20, the CPU 14 proceeds to step S203 (YES side). On the other hand, when the “No” button signal is received, the CPU 14 proceeds to step S204 (NO side).

  Step S203: The priority information changing unit 24 collectively changes the priority information of the metadata added to all the images recorded on the storage medium 17a in response to a priority information change instruction from the user. . For example, the priority information of the metadata added to the Raw image is changed from “true” to “false”, and the priority information of the metadata added to the JPEG image is changed from “false” to “true”. Is done. Alternatively, only the priority information of metadata added to the Jpeg image may be changed from “false” to “true”.

Step S204: The priority information changing unit 24 changes only the priority information of the metadata added to the image selected by the user among the image files of the Raw image and the JPEG image recorded in the storage medium 17a. Specifically, based on the hash value information of the metadata, the CPU 14 recognizes the image file of the Raw image and the JPEG image obtained by the same imaging as an image file group in association with each other. Based on the recognition result of the image file group, the display control unit 27 displays thumbnails of all the image file groups on the monitor 19 as one thumbnail display for each image file group. The priority information changing unit 24 receives an instruction to select and change an image file group whose priority is to be changed by a user via a touch panel (not shown) arranged in front of the monitor 19 among the thumbnails displayed in a list. . The priority information changing unit 24 changes the metadata priority information added to the selected image file group in the same manner as in step S203.
3) Example of Operation of Computer 2 Next, an example of the operation of the computer 2 in the present embodiment will be described with reference to the flowchart of FIG. The processing in FIG. 5 is started when the CPU 34 executes the image processing program in response to a program execution instruction from the user.

  Step S301: The CPU 34 acquires, from the electronic camera 1, image files of a plurality of RAW images and JPEG images captured by the electronic camera 1 set in each recording mode and priority setting mode. The transfer of the image file between the electronic camera 1 and the computer 2 is realized by exchanging the storage medium 17 a from the data reading unit 31 or data communication via the communication unit 32. The acquired image file is recorded in the storage device 33 or the memory 35 under the control of the CPU 34. The CPU 34 preferably records the acquired image file according to the storage medium 17a of the electronic camera 1 that is the transmission source or the folder hierarchy of the storage device 33 or the memory 35 of the computer 2 that is the reception side.

  Step S302: The CPU 34 recognizes the folder hierarchy of the storage device 33 or the memory 35 according to the image processing program, and displays the folder hierarchy on the monitor 39 as a tree. The CPU 34 selects, from the displayed folder hierarchy, a folder in which the image file of the Raw image and the JPEG image acquired from the electronic camera 1 in step S301 is recorded based on the selection instruction of the input device 38.

  Step S303: Based on the hash value information of the metadata added to each image in the folder selected by the user, the CPU 34 recognizes the image file of the Raw image and the Jpeg image obtained by the same imaging as an image file group. To do. In this embodiment, whether or not the same image is captured is determined based on the hash value. However, the image file name of the Raw image and the Jpeg image, or the file name of the image file of the Raw image and the Jpeg image are added. It may be recognized with reference to the file name information of the raw image of the metadata that has been set.

  Step S304: Based on the recognition result of the image file group in step S303, the CPU 34 displays a list of thumbnails of image pickup units on the monitor 39 as one thumbnail display for each image file group, as in step S204. Do. For example, in the folder selected in step S302, there are 10 and 7 image files for the Raw image and the JPEG image, respectively, and the number of image file groups recognized as the same image file in step S303. In the two cases, the CPU 34 displays a list of 15 (= 10 + 7-2) thumbnails on the monitor 39.

  Step S305: The CPU 34 selects an image file group corresponding to the thumbnail in response to a selection instruction from the input device 38 (such as a user clicking a thumbnail displayed on the monitor 39). The CPU 34 identifies the priority information of the metadata added to each image file of the selected image file group. Based on the identification result, the CPU 34 displays the image information of the image file whose priority information is set to “true” on the monitor 39.

  That is, in the case of an image file of a Raw image captured in the first recording mode or a JPEG image captured in the second recording mode, the metadata priority information is set to “true”. The CPU 34 displays on the monitor 39 metadata of the image file of the Raw image or Jpeg image, information on imaging conditions such as shutter speed and aperture value, and image information including at least one of image histogram, image size, and color space. To do. On the other hand, in the case of an image file of a Raw image and a Jpeg image captured in the third recording mode, the priority information of the metadata of the image file of the Raw image and / or Jpeg image is set to “true”. The CPU 34 displays the image information of the image file whose priority information is set to “true” on the monitor 39.

  Note that information such as an image histogram, an image size, and an image color space generally differs depending on the file format of the image, or some information is not required. Therefore, for example, in the case of an image size, the CPU 34 displays information indicating which image metadata is specified, such as “image size: 4256 × 2832 (Raw)”, or information that is not required. Is preferably not displayed.

  Step S306: When the CPU 34 receives another selection instruction from the input device 38 (such as a user double-clicking a thumbnail displayed on the monitor 39), the CPU 34 selects an image file group corresponding to the thumbnail. The CPU 34 identifies the priority information of the metadata added to the image file of the selected image file group. Based on the identification result, the CPU 34 performs image processing on the Raw image and / or Jpeg image whose priority information is “true” among the image files of the selected image file group. The CPU 34 records the image data subjected to the image processing in the storage device 33 or the memory 35 and ends the series of processing.

  Here, the image processing includes interpolation processing, white balance processing, gradation conversion processing, noise removal processing, contour enhancement processing, color conversion processing (calculation using a color conversion matrix, etc.), gamma conversion, and the like. In executing image processing, the CPU 34 preferably displays a setting screen for setting processing contents and parameter values on the monitor 39 in accordance with an instruction from the input device 38 in advance. In addition, when receiving a selection instruction from the input device 38, the CPU 34 may activate another image processing program in order to perform image processing on the selected image file group.

As described above, in the present embodiment, even if two image files of a raw image and a jpeg image are generated by the same imaging, any image is preferentially selected before the electronic camera 1 captures the main image. By generating priority information on whether or not to perform, display of image information and image processing by the electronic camera 1 and the computer 2 can be handled as one image file.
