An outline of the system shown in FIG. 1 will be described. As shown in the figure, an image reading device 1 for taking in an image as digital data, such as a scanner, is provided on a system bus 100 for passing control signals and image data.
01, an image output device 102 such as a printer for outputting an image onto recording paper such as paper or an OHP sheet, an image display device 103 for displaying and confirming an image such as a monitor, a storage device 104 such as a hard disk or a magneto-optical disk, and processing to the device An operation / input device 105 for inputting and displaying instructions / settings, a control device 106 for controlling each device, an image processing device 107 for processing / editing digital image data, and communication for connection with a communication network such as encoding / decoding.

In the above configuration, the method of defining the color psychological parameter and the color adjusting process The process in the color psychological parameter mode The process in the color psychological parameter combination / separation mode The process in the color psychological parameter learning mode The process in the color psychological parameter output mode Personal management Processing in mode The operation will be described in the order of processing in the multiple output mode.

Definition of Color Psychological Parameters and Method of Color Adjustment Processing The definition of color psychological parameters and the method of color adjustment processing in the image processing apparatus 107 which are particularly important in the present invention will be described with reference to FIGS. 2 and 3.

The color psychological parameter referred to here is a series of processes that help the user to quickly reach the desired output color setting, and are replaced with words that are similar to human senses. For example, when a user looks at a manuscript when he / she has the impression that it is "dark and not dull,""I want to make the colors clearer,""more bright,
I would like processing such as "I want to release it". Therefore, such a request for processing close to human sensibilities is defined together with a series of complicated processing as color psychological parameters, and processing is selected and processed according to the property of the target image.

An image having the impression that it is "dark and not dull" uses its RGB data as the uniform color space CIEL.
When converted to L * a * b * of AB and plotted, the lightness L
The distribution will be like the distribution 200 of FIG. 2 (a), where * is low and is concentrated near the L * axis, that is, the saturation is low.
Therefore, in order to gain the saturation, as shown in the distribution 201 of FIG.
Spread it in the saturation direction of * b * to make the color clear. In addition, in the case of clear light, the distribution 202 in FIG.
As described above, the process of shifting the distribution 200 in the lightness direction is “vividly” as the color psychological parameter,
It is defined by the sensuous word “clear”, and a series of processes (combination of a plurality of color adjustment parameters) that can be realized are stored in the storage device 104 in a one-to-one correspondence.

FIG. 3 is a schematic flowchart showing a method of color adjustment processing in the image processing apparatus 107. The image processing apparatus 107 receives the RGB data (S30
1), the uniform color space CIELAB is converted to L * a * b * (S302, S303).

Next, based on the color psychological parameter designated by the user, a corresponding series of processing (combination of a plurality of color adjustment parameters) is input from the storage device 104, and the series of processing is performed by the main processing unit for color adjustment. Is executed (S30
4). For example, when the color psychological parameter is “vivid”, the operation for expanding the saturation is performed in the main processing unit, and when the color psychological parameter is “light”, the function L * for shifting the lightness in the main processing unit is used. Perform '= L * + offset. In addition, various functions such as hue rotation, expansion, compression and movement can be easily defined. The details of the coefficient k and offset used in S304 will be described later.

After that, the uniform color space C changed in S304
The L * 'a *' b * 'of IELAB is converted into R'G'B' data (S305, S306). Through the above steps, the image processing apparatus 107 executes the color adjustment processing based on the color psychological parameter.

Processing in Color Psychological Parameter Mode Next, referring to the flowchart of processing in the color psychological parameter mode of FIG. 4, the user operates / input device 1
The control contents of the control device 106 when the color psychological parameter is designated via the image display device 103 and the image display device 103 will be described.

RGB of the target image is converted into L * a * b * and statistical processing is performed (S401). In this embodiment, the CIELAB space is taken up, but CIE LUV, HLS space or the like may be used as long as it is a three-dimensional space.

As a result of the statistical processing of S401, L *, a *,
The maximum and minimum values and average values of b * are calculated, and these are extracted as distribution characteristic data (S402). Image: L2 ≤ L * ≤ L3, -a2 ≤ a * ≤ a3, -b
2 ≤ b * ≤ b3

Next, since the upper and lower limits such as the coefficient k shown in FIG. 3 differ depending on the output device, the output device is selected (S403). Here, since the image display device 103 and the image output device 102 can be selected as the output devices, the value of the coefficient k differs depending on which of the two is output. That is, since the former has a wide color reproduction range and the latter has a narrow color reproduction range, the coefficient k has a proportional relationship. These allowable ranges are values that are known in advance by the manufacturer for color correction of the system.

In this example, assuming output to the image output device 102, the device: L0 ≤L * ≤L1, -a0 ≤a * ≤a1, -b
0 ≦ b * ≦ b1, and as described above, from the characteristic data of the distribution, the maximum and minimum values of L *, a *, and b * are L2 ≦ L.
Since * ≤L3, -a2 ≤a * ≤a3, -b2 ≤b * ≤b3, the coefficient k is, for example, k = max (a0, a1, b0, b1) / max as shown in FIG. (A2
, A3, b2, b3).

In the lightness shift, as shown in FIG. 6, for example, a definition such as offset = L2 is registered (stored) in the storage device 104 in advance.

Next, the color psychological parameters stored in the storage device 104 are displayed on the image processing device 107 (S40).
4) When the user selects a desired color psychological parameter via the operation / input device 105 (S405), the image processing apparatus 107 executes the color adjustment processing defined by the color psychological parameter based on the characteristic data. Yes (S40
6). At this time, how much the coefficient of the main processing unit of the image processing apparatus 107 is shaken depends on how to define it, but there is also a method in which the user inputs or selects this swing width. this is,
The characteristic data of the distribution extracted in S402 is used as the image display device 1.
03, and in the step of the processing based on the characteristic data after selecting the color psychological parameter, the characteristic data of the distribution that prompts the processing is displayed on the image display device 103, and the parameter in the main processing unit is left to the user. Is.

The output in S407 means the communication by the image display device 103, the image output device 102, the storage device 104, and the communication device 108, which is the selected output destination of the processed image, or to the device via the external I / F. This is an output process. As a matter of course, it is also possible to perform normal color processing before and after the processing in the color psychological parameter mode.

By the above process, the user directly selects the color psychological parameter replaced by the sensory words, thereby eliminating the complicated setting of the color adjustment process inherent to the color device, and the image according to the preference. Can be obtained quickly.

Processing in Color Psychological Parameter Combination / Separation Mode FIG. 7 shows a flowchart of processing in the color psychological parameter combination / separation mode. The color psychological parameter combination / separation mode is a number of color psychological parameters defined,
For example, frequently use "bright" and "brightly", select multiple color psychological parameters newly when you want to set them at once, and make "registered name" attractive so that the registered name does not overlap with the defined name. Name it and register in the registration mode. In addition, the separation means that a * b * is included in the color psychological parameters as shown in the main processing unit “vividly” in FIG.
There is a definition of multiple expressions related to. Select this when you want to set it independently. Separation form input means, when multiple expressions are three or more, and if they are divided into two, the above two expressions are one set,
This is processing related to the grouping method such that the following two equations are one group.

The control device 106 is an operation / input device 105.
When a predetermined key (not shown) is pressed to specify the color psychological parameter combination / separation mode, the process of FIG. 7 is executed. First, the color psychological parameters stored in the storage device 104 are displayed as a list on the image display device 103, and the user is prompted to select either a combination process or a separation process (S701). When the user selects a process via the operation / input device 105, it is determined whether or not the process is a combination process (S702). Is input (S703). Next, the user is prompted to enter the name of the color psychological parameter to be newly registered, and operation /
When the name is input through the input device 105 (S70
4), define the color psychological parameter with the new name, S70
The processing systems of the color psychological parameters selected in 3 are combined and stored in the storage device 104 (S705).

On the other hand, if it is not the combination process, the selection of the color psychological parameter to be separated is input (S706), it is determined whether or not the color is separable (S707), and if it is separable, the separated individual colors are separated. The name of the psychological parameter (the name to be newly registered) is input (S708), and then the separation mode is input (S709). Then, in S705, the color psychological parameter is defined with a new name, and based on the separation form,
The processing system is separated and stored in the storage device 104.

By the above processing, it is possible to edit the color psychological parameter registered in the storage device 104 in advance. If you frequently use multiple processes, you can specify the process only once by combining. In addition, it is possible to select detailed processing by separation.

Processing in Color Psychological Parameter Learning Mode FIG. 8 shows a flowchart of processing in the color psychological parameter learning mode. In the color psychological parameter learning mode, color psychological parameters are registered in advance with priorities, and in the color psychological parameter mode, image feature data and color psychological parameter history are stored in the storage device 104.
This is a mode in which the frequently used processing can be automatically specified and processed based on the relationship between the color psychological parameter and the image. It is assumed that the color psychological parameter learning mode is designated to be turned on or off by the user's selection via the operation / input device 105.

When the color psychological parameter learning mode is designated, the control device 106 executes the processing shown in FIG. Note that the flowchart of FIG. 8 is basically the same as the flowchart in the processing of the color psychological parameter mode of FIG. 4, and the same reference numerals indicate common processing, so only the different portions will be described here.

When statistical processing, extraction of distribution characteristic data and selection of output device (S401 to S403) are performed,
The control device 106 is stored in the storage device 104,
Based on the priority of the color psychological parameters and the image feature data and the history of the color psychological parameters in the color psychological parameter mode so far, the color psychological parameters assumed to be most suitable for the color adjustment processing of the corresponding image are The recommended color psychological parameter is displayed on the image display device 103, and the color adjustment based on the recommended color psychological parameter is automatically executed (S801).

Then, through the operation / input device 105,
Whether or not the color adjustment based on the recommended color psychological parameter is acceptable is input. If it is OK (good), the characteristic data and the selected color psychological parameter are output after outputting to the output destination selected in S407. The history is held in the storage device 104 (S803), the frequency of use of each feature data for each color psychological parameter stored in the storage device 104 is calculated, and the priority of the color psychological parameter is updated (S80).
4), the process ends.

On the other hand, if it is not OK in S802, the process proceeds to S404 to S406, the color psychological parameter stored in the storage device 104 is displayed on the image processing device 107, and the user operates the operation / input device 105. When the desired color psychological parameter is selected, the image processing apparatus 107 executes the color adjustment processing defined by the color psychological parameter based on the feature data.
