Description

  The present invention relates to an image processing technique for performing color conversion on an image.

2. Description of the Related Art In recent years, a technique has been proposed for performing desired color conversion processing on a photographed image using three-dimensional lattice point data or the like for image data photographed by an imaging device such as a digital camera. Furthermore, assuming that the user uses the color conversion processing in a personal computer (hereinafter referred to as a PC), a technique for storing image data and three-dimensional lattice point data in association with each other has been proposed (for example, Patent Documents). 1)
Further, a technique has been proposed in which a user performs a desired color conversion process on image data using an image editing application (hereinafter referred to as a PC application) such as a PC. In addition, a technique has been proposed in which three-dimensional lattice point data created by using this PC application is saved as a file so that it can be used by a digital camera or a PC application.

Generally, in a digital camera, hardware size and actual processing time are given priority. Therefore, low-order three-dimensional lattice point data that is less accurate than three-dimensional lattice point data used in a PC application may be used. . However, in order to use an image file taken with a digital camera in a PC application, there is a problem that the file size increases when high-order three-dimensional lattice point data is stored in the header area of the image file. On the other hand, there is a method in which low-order three-dimensional lattice point data can be used on the PC application side by writing low-order three-dimensional lattice point data used by the digital camera in the header area of the image file.

  The embodiment described below is an example as means for realizing the present invention, and should be appropriately modified or changed according to the configuration of the apparatus to which the present invention is applied and various conditions. It is not limited to the embodiment.

  The image processing system according to the present embodiment includes an imaging device 400 such as a digital camera that captures moving images and still images, and an image processing device such as a PC (see FIG. 4) that performs color conversion processing of a captured image using a PC application. Are configured to be communicable.

  FIG. 1 is a block diagram illustrating a configuration of a color conversion data generation unit 100 of a PC application according to an embodiment of the present invention.

  In FIG. 1, reference numeral 101 denotes a data input / output unit for inputting / outputting image data from / to an external device such as an imaging apparatus or a memory medium. An image processing unit 102 executes color conversion processing on the image data. Reference numeral 103 denotes an operation input unit for the user to set color adjustment parameters (color conversion conditions) as conditions relating to color conversion processing for image data. A display unit 104 displays the color adjustment parameters specified by the operation input unit 103 and the color conversion processing result by the image processing unit 102 on a display or the like. A data holding unit 105 holds various data such as image data, a place where color conversion processing has been performed, a color adjustment parameter change history, and profiles before and after the color conversion processing. Reference numeral 106 denotes color conversion data composed of low-order (first color conversion data) and high-order (second color conversion data), which will be described later with reference to FIG. 5, based on the color adjustment parameters used in the final color conversion processing. It is a color conversion data output unit that generates a file (color conversion data file). The color conversion data output unit 106 outputs the generated color conversion data file to an external memory medium and stores it.

  Next, a color conversion data generation process by the color conversion data generation unit of the present embodiment will be described with reference to FIG.

  In FIG. 2, first, image data photographed by an imaging device or the like is input via the data input / output unit 101 (S201), and stored in an input data storage area of the data holding unit 105 (S202).

  Next, the image processing unit 102 performs color conversion processing on the image data stored in the data holding unit 105 based on the color adjustment parameter designated by the user via the operation input unit 103 (S203). . Here, a known technique may be used for a color space that is easy for the user to operate intuitively, such as an HSL space. In general, the color conversion process is often repeated a plurality of times.

  When the color conversion process is completed in S203, the color conversion data used for the color conversion process is stored in the data storage area of the data holding unit 105 (S204). The color conversion data is displayed on the display unit 104 (S205).

  Next, the color conversion data output unit 106 generates a color conversion data file used for the final color conversion processing and outputs it to an external memory medium (S206).

  FIG. 3 illustrates a GUI (setting unit) for the user to perform a color adjustment parameter setting operation.

  The GUI (graphic user interface) in FIG. 3 is roughly divided into the following four functional blocks 301 to 305. That is, reference numeral 301 denotes a pre-processing image display unit that displays original image data before color conversion processing (image data before color conversion). A post-processing image display unit 302 displays image data after color conversion processing (image data after color conversion). Reference numeral 303 denotes an image adjusting unit having an operation unit for adjusting the color of the image in detail. A change history display unit 304 displays a color adjustment parameter change history.

  The data input to the data input / output unit 101 is stored in the input data storage area of the data holding unit 105 in S202 of FIG. The original image data stored in the data holding unit 105 is displayed on the pre-processing image display unit 301 that constitutes a part of the display unit 104 in FIG. The parameter setting unit 303 constituting the operation input unit 103 in FIG. 1 changes the range of color conversion for the original image data based on the color adjustment parameter designated by the user, and transfers it to the image processing unit 102. Examples of the color adjustment parameters include hue (hue), color density (saturation), and brightness (lightness).

  The image processing unit 102 generates color conversion data from the color adjustment parameter set by the user and stores it in the data storage area of the data holding unit 105 (S204). Further, the image data after the color conversion process is displayed on the processed image display unit 302 constituting a part of the display unit 104 (S205).

  Then, the color conversion process is performed at least once (usually a plurality of times) according to the setting operation by the user, and the color conversion process ends when a color conversion process result that satisfies the user is obtained. At this time, the color adjustment parameter is displayed on the change history display unit 304 and stored in the color adjustment parameter storage area of the data holding unit 105. Further, when the user presses the save button 305, the color conversion data file used for the final color conversion processing is output from the color conversion data output unit 106 to an external memory medium and stored (S206).

  Although details will be described later, the color conversion data file includes low-order three-dimensional grid data used for color conversion processing in the imaging apparatus and high-order three-dimensional data used for color conversion processing in the PC application. Includes both grid point data.

  FIG. 4 is a block diagram illustrating an image processing system including an imaging device and a PC that configure the image processing system of the present embodiment.

  In FIG. 4, in the imaging apparatus 400, an imaging unit 401 includes an imaging lens (not shown), an imaging element such as a CMOS sensor and a CCD, a driving circuit, a gain circuit, and the like, and an optical image formed on the imaging lens is captured by the imaging element. Is converted into an electric signal. An analog signal output from the imaging unit 401 is converted into a digital signal by the A / D converter 402. The timing generation circuit 403 supplies a clock signal and a control signal to the imaging unit 401, the A / D converter 402, the D / A converter 407, and the like, and is controlled by the memory controller 404.

  The memory controller 404 controls the A / D converter 402, the timing generation circuit 403, the buffer memory 405, the D / A converter 407, and the like. The memory controller 404 controls the white balance processing unit 410, the development processing unit 411, the three-dimensional lattice point data processing unit 412, the JPEG compression unit 413, the RAW compression unit 414, and the like.

  The image data converted into a digital signal by the A / D converter 402 is written into the buffer memory 405 via the memory controller 404. The white balance processing unit 410 performs known white balance processing on the image data written in the buffer memory 405. The development processing unit 411 performs known pixel interpolation processing, gradation processing, color matrix processing, and the like on the image data in the buffer memory 405 that has been subjected to white balance processing. The three-dimensional lattice point data processing unit 412 performs color conversion processing on the image data subjected to the development processing by the development processing unit 411 using color conversion data described later.

  The external storage medium 422 is composed of a memory card or the like made of a semiconductor memory, and is detachable from the imaging device. The image data stored in the buffer memory 405 is written to the external storage medium 422 via the memory controller 404 and the I / F 421. The image display unit 408 displays a captured image via the D / A converter 407. The system control circuit 420 controls the entire imaging apparatus, and also performs imaging control such as the nonvolatile memory 406, light adjustment (not shown), AF, and AE. The I / F (interface) 423 is connected to the color conversion data file writing unit 510 mounted on the PC 500 via the I / F 511 of the PC 500.

  The color conversion data file writing unit 510 has a function of transferring low-order three-dimensional lattice point data among the color conversion data files stored in the storage unit 513 to the imaging apparatus 400, and via the I / F 512. A storage unit 513 is connected. The storage unit 513 stores the color conversion data file created by the color conversion data generation unit 100 of FIG.

  FIG. 5 illustrates the structure of the color conversion data file stored in the storage unit 513.

  As shown in FIG. 5, the color conversion data files 5110, 5120, and 5130 have file headers 5111, 5121, and 5131 for identifying the files. The color conversion data files 5110, 5120, and 5130 include low-order three-dimensional lattice point data 5112, 5122, and 5132, and high-order three-dimensional lattice point data 5113, 5123, and 5133, respectively.

  Here, a process of transferring the color conversion data file 5110 from the PC 500 to the imaging apparatus 400 will be described with reference to the flowchart of FIG.

  In FIG. 6, the color conversion data file writing unit 510 establishes communication with the system control circuit 420 via the I / Fs 423 and 511 (S601).

  If the communication is OK, the process proceeds to S602, and if it is NG, the process waits until communication is established again.

  Next, the user selects a color conversion data file 5110 stored in the storage unit 513 via a GUI (not shown) of the color conversion data file writing unit 510 (S602).

  Next, the low-order three-dimensional lattice point data 5112 in the color conversion data file 5110 selected by the user is taken into the color conversion data file writing unit 510 and transferred to the imaging device 400 via the I / F 423,511. Is done. In the imaging apparatus 400, the low-order three-dimensional lattice point data 5112 received from the PC 500 is stored in the nonvolatile memory 406 (S603), and when the data transfer is completed, the communication is terminated (S604).

  In step S <b> 603, the color conversion data file writing unit 510 can simultaneously transfer related information associated with the low-order three-dimensional lattice point data 5112 to the nonvolatile memory 406 of the imaging apparatus 400. Here, the selected one low-order three-dimensional lattice point data 5112 is transferred to the imaging apparatus 400, but a plurality of three-dimensional lattice point data (for example, low-order three-dimensional lattice point data 5122 and 5132) are selected. However, they can be transferred at the same time. In this way, three-dimensional lattice point data used for color conversion processing in the imaging apparatus 400 can be transferred from the PC 500 to the imaging apparatus 400.

  Returning to FIG. 4, the three-dimensional lattice point data processing unit 412 will be described.

  The three-dimensional lattice point data processing unit 412 converts Y, U, and V into Y ′, U ′, and V ′ based on the three-dimensional lattice point data with respect to the image data developed by the development processing unit 411. In this embodiment, it is assumed that low-order three-dimensional lattice point data 5112 stored in the nonvolatile memory 406 is used as three-dimensional lattice point data. Generally, in hardware, it is necessary to give priority to the circuit scale, actual processing time, and memory capacity. In the present embodiment, YUV lattice point data in 9 × 9 × 9 three-dimensional representative lattice point data obtained by dividing the YUV signal into 8 parts is prepared. It should be noted that YUV signals other than these grid points are obtained by interpolation processing.

  FIG. 9 is a conceptual diagram of three-dimensional lattice point data, and each lattice point contains a converted YUV value. The details of the interpolation method are well known and will not be described here, but general interpolation processing is performed.

  The three-dimensional lattice point data processing unit 412 executes a conversion process using the following equation 1 based on the created three-dimensional lattice point data.

(Yout, Uout, Vout) = DATA [Y, U, V] (1)
For example, when the input data to the three-dimensional lattice point data processing unit 412 is the YUV value at the point 901, the YUV value at the point 902 is (Yout, Uout, Vout) as a result of executing the conversion process according to the above equation 1. Become.

  Returning to the description of FIG. 4, the image data subjected to the color conversion processing by the three-dimensional lattice point data processing unit 412 is subjected to known JPEG compression processing by the JPEG compression unit 413, and is externally stored via the I / F 421. The data is output and stored on the medium 422.

  In addition, the RAW compression unit 414 performs lossless compression processing on the data converted into a digital signal by the A / D converter 402 and written in the buffer memory 405. An image file composed of a file header, low-order three-dimensional lattice point data, thumbnail (reduced) image, and display image data together with the RAW data subjected to the lossless compression processing is transferred to the external storage medium 422 via the I / F 421. Is output and stored.

  As described above, the imaging apparatus 400 generates and stores an image file that stores the three-dimensional lattice point data used for the color conversion process together with the RAW data.

  Next, a case where the color conversion data file created by the color conversion data generation unit 100 in FIG. 1 is subjected to image processing with a PC application will be described.

  The PC application is preinstalled on the PC 500, and the color conversion data file of FIG. 5 is stored in the storage unit 513 of the PC 500.

  FIG. 7 is a flowchart when color conversion processing is performed by a PC application using the color conversion data file generated by the color conversion data generation unit 100 of FIG.

  In FIG. 7, the PC application decodes the file header of the image file 801 in FIG. 8 input from the imaging device 400 and extracts low-order three-dimensional lattice point data 802 (S701).

  Next, the PC application compares the three-dimensional lattice point data stored in the storage unit 513 with the low-order three-dimensional lattice point data 802 extracted from the image file, and stores the low-order three-dimensional lattice point data 802 in the storage unit 513. Is searched for whether there is a match (S702). If the same data as the low-order three-dimensional lattice point data 802 exists in the storage unit 513 in S703, the higher-order color conversion data file stored in the storage unit 513 of the PC 500 as shown in FIG. Color conversion processing is executed using the three-dimensional lattice point data 804 (S704).

  In FIG. 8A, the image data stored in the image file 801 is decoded, the RAW data 803 is extracted, the image processing 805 is performed, and then the three-dimensional lattice point data processing 806 is performed. This three-dimensional lattice point data processing 806 takes out higher-order three-dimensional lattice point data (for example, 33 × 33 × 33) from the color conversion data file of FIG. 5 and uses it in the PC application. As described in FIG. 5, the color conversion data of the present embodiment includes three-dimensional lattice point data of 33 × 33 × 33 higher than 9 × 9 × 9. The color conversion processing by the PC application has more memory capacity than the digital camera, so higher-order three-dimensional lattice point data that uses about 50 times the representative lattice point compared to the processing by the digital camera is used. As a result, more accurate color conversion processing is possible.

  On the other hand, if there is no match in S703, image processing is performed using low-order three-dimensional lattice point data 814 stored in the image file 801 input from the imaging device 400, as shown in FIG. Is executed (S705).

  In FIG. 8B, the image data stored in the image file 801 is decoded, the RAW data 803 is extracted, the image processing 815 is performed, and then the three-dimensional lattice point data processing 816 is performed. This three-dimensional lattice point data processing 816 uses low-order three-dimensional lattice point data 814 stored in the image file 801. Thus, when color conversion data is not prepared on the PC 500, image processing is performed using the low-order three-dimensional lattice point data 814 stored in the image file.

  As described above, when the color conversion data file created by the color conversion data generation unit 100 in FIG. 1 is stored on the PC 500 and can be used in the PC application, higher-order three-dimensional lattice point data is used. It is possible to perform highly accurate image processing.
