Thus, a beginner easily performs an adjustment of the color of the part selected by him by adjusting the color to the color which is beforehand stored in a storage device of the device 2 or to the color which is modified somewhat.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color adjusting device for an image display device such as a monitor.

[0002]

2. Description of the Related Art Conventionally, color adjustment has been configured such that a user operates a volume such as color tone, saturation, and brightness.

[0003]

However, in the above-mentioned conventional example, since a plurality of volumes are operated, a skill is required for use, and an unskilled person cannot easily adjust the volume.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a color adjusting device capable of performing color adjustment by a simple operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, FIG. 1 shows a block diagram of a first embodiment.
Reference numeral 1 is an image display device such as a monitor, 2 is an overall control device incorporating a storage device such as a personal computer, 3 is an instruction device such as a mouse, and 4 is an input device such as a keyboard.

Next, FIG. 2 shows a flow chart of the first embodiment (hereinafter, each step is abbreviated as S). First, S1
In, it is checked whether or not the pixel position for which color adjustment is desired is designated by the designating device 3, and if it is designated,
The process proceeds to S2, and if not, the process returns to S1. And
In S2, several pixels around the designated pixel are set as the first pixel region, and the process proceeds to S3. The size of the first pixel area can be set to any size. Further, the width of the pixel area may be automatically changed according to the image data. Further, the instruction mark of the pointing device displays both the pixel designated by the pointing device and the first pixel region. Then, in S3, if the color adjustment start command is input from the input device 4, the process proceeds to S4, and if not, S
Return to 1. Then, in S4, the process waits for the input device 4 to input what color the color of the first pixel area determined in S2 is to be adjusted. Then, in S5,
If the color adjustment instruction is input, the process proceeds to S6, and if not, the process returns to S4. Then, in S6, according to the color adjustment instruction input in S5, the average value of the colors of the first pixel area is adjusted to the instructed color, and the color of the second pixel area wider than the first pixel area is adjusted. As an adjustment sample, one axis has several kinds of second pixel areas adjusted to the color estimated to have been instructed, and the other axis has changed the luminance of the color adjusted second pixel areas. Several kinds of items are displayed and the process proceeds to S7. Then, in S7, when the optimum image is selected from the color adjustment samples created in S6, the process proceeds to S8,
If not, S7 is repeated. Then, in S8, all the images are adjusted by the color adjustment sample selected in S7, and the process proceeds to S9. Then, in S9, the instruction for storing the color adjustment data of the selected color adjustment sample is the input device 4
If it is input from, the process proceeds to S10, and if not, it becomes END. Then, in S10, the color adjustment data of the selected color adjustment sample is stored with the name input from the input device 4 and becomes END. The color adjustment data is stored with the same date and time data as the image data.

Now, this embodiment will be described more specifically with reference to FIGS. 3 and 4 which are explanatory views of the first embodiment. First, FIG. 3 shows a state in which the image before color adjustment is displayed at the image display position 1, and shows that the face portion of the image is designated by the pointing device 4.
Pixels designated by the pointing device 4 are indicated by crossing intersections,
The circle represents the first pixel area. In this case, since the face is larger than the circle representing the first pixel area, there is no problem. However, if not, the input device 4 is operated to change the size of the circle representing the first pixel area. be able to. If the circle representing the first pixel area is still large, the color of pixels other than the face is also used for the adjustment data, and correct adjustment cannot be performed. In the color adjustment, the average color data of the first pixel area obtained by averaging the colors in the circle representing the first pixel area is obtained, and this color data matches the color data of the storage device built in the overall control device 2. To do so.

Next, FIG. 4 shows a state in which the image after color adjustment is displayed on the image display device 1, and the average value of the colors of the first pixel area is built in the overall control device 2. As a color adjustment sample for the second image area wider than the first pixel area by adjusting to the instructed color data of the storage device, one axis is adjusted to the estimated instructed color 2 kinds of pixel areas, the other axis is the color-adjusted second
Several types in which the brightness of the pixel area of (1) is changed are displayed at positions other than the adjusted pixel area in the screen. The sample selected from these color adjustment samples is indicated by a white frame, and the image is adjusted to the color of the selected sample.
Here, an input command to the overall control device 2 when adjusting the average value of the color of the first pixel region to the color data of the storage device built in the overall control device 2, for example, in the present embodiment, In the image of, the designation is made such as "female face". And
The overall control device 2 determines several types of colors estimated to have been instructed, based on the input command and data such as the date and time when the image was captured or input, the location, and the like. Further, since the first pixel area is not always properly exposed, several kinds of color adjustment samples of under and over are prepared for each of several kinds of colors. Then choose from these color adjustment samples,
The color adjustment ends. Then, after the color adjustment is completed, the color adjustment data is added to the color data of the storage device built in the overall control device 2 and is used in the color adjustment from the next time. On this occasion,
If you know the name of the subject woman, you can register it with a name such as "Mr. XX's face", and you can easily adjust the color from the next time.

Now, FIG. 5 will be described. Here, an example of an instruction mark of the instruction device that displays both the pixel instructed by the instruction device 4 and the first pixel region is shown. The instruction mark can clearly display the pixel indicated by the indicating device and the first pixel area. Here, in the present embodiment, the average value of the colors of the first pixel area is adjusted to the instructed color, but the colors of the first pixel area are not averaged, the weighting is changed, and the center emphasis is applied. By doing so, even when the first pixel region includes a pixel different from the pixel designated by the pointing device, the influence thereof is smaller than that in the case of averaging. However, since it has some influence, it is better not to include a pixel different from the designated pixel. Therefore, if the instruction mark of the pointing device that displays the first pixel area is enlarged and an image in which the first pixel area is enlarged can be displayed in the pointing mark, the first pixel area is This makes it easier to avoid inclusion of a pixel different from the designated pixel.

In the above embodiment, the color adjustment at one place was described, but the color adjustment at one place may cause the color of the other image to be greatly shifted. Adjustment is required in a plurality of pixel areas. In that case, since it is not possible to make adjustments so that all of the color adjustments are performed multiple times, the first adjustment data is given the highest priority, and the priority is reduced as the number of times increases for the second and third times. Make adjustments.

[0013]

As described above, in the present invention, the user selects a portion to be adjusted with the pointing device such as a mouse and inputs what it is, and the color adjustment sample is displayed. The color adjustment is completed only by selecting from among them.
