Description

本発明は、複数台のモニタの色を合わせる技術に関する。   The present invention relates to a technique for matching colors of a plurality of monitors.

一般に、複数台のプロジェクタで1つの画像を表示するマルチプロジェクションシステムや、大きな会場で様々な場所にモニタを設置する場合のように、複数台のモニタの色合わせをすることが必要となることがある。   In general, it is necessary to perform color matching of a plurality of monitors, such as a multi-projection system that displays a single image with a plurality of projectors, or a monitor installed in various places in a large venue. is there.

ところで、従来から、色調節対象のモニタに表示された画像データの色と、印刷物に印刷されている画像データの色とを人の目で比較することにより、このモニタの色を、印刷物の色に合わせる様々な技術が知られている(例えば、特許文献1〜4参照)。   By the way, by comparing the color of the image data displayed on the color adjustment target monitor with the color of the image data printed on the printed material, the color of this monitor is conventionally changed to the color of the printed material. Various techniques are known to meet these requirements (see, for example, Patent Documents 1 to 4).

理論上、これらの技術を用いて、各モニタの色を、印刷物の色に合わせれば、複数台のモニタの色を合せられる筈である。   Theoretically, if these monitors are used to match the color of each monitor to the color of the printed matter, the colors of a plurality of monitors should be matched.

しかしながら、印刷物とモニタという異なるメディア間の色合わせになるため、現実には、色調整が難しく感じられ、また精度も良くない場合がある。

以下に、本発明の最良の一実施形態を説明する。   The best embodiment of the present invention will be described below.

本実施形態では、色調整対象のモニタに表示された画像データの色と、印刷物に印刷されている画像データの色とを人の目で比較することにより、色調節対象のモニタの色を、印刷物の色に合わせる任意の公知の技術を応用する。但し、印刷物の代わりに、正しい色特性を持つモニタを基準モニタとして用い、印刷物に印刷される画像データを、基準モニタに表示させ、色調整対象のモニタに表示された画像データの色と、基準モニタに表示させた画像データの色とを人の目で比較することにより、色調節対象のモニタの色を、基準モニタに合わせる。   In the present embodiment, by comparing the color of the image data displayed on the color adjustment target monitor and the color of the image data printed on the printed material with the human eye, the color of the color adjustment target monitor is obtained. Any known technique for matching the color of the printed material is applied. However, instead of the printed material, a monitor having the correct color characteristics is used as the reference monitor, the image data printed on the printed material is displayed on the reference monitor, and the color of the image data displayed on the color adjustment target monitor and the reference By comparing the color of the image data displayed on the monitor with the human eye, the color of the color adjustment target monitor is matched with the reference monitor.

正しい色特性は、任意に定めて良い。例えば、後述する例のように、印刷物と同じ色を表示させるものであっても良いし、ユーザの好む色を表示させるものであっても良い。   Correct color characteristics may be arbitrarily determined. For example, as in the example described later, the same color as the printed material may be displayed, or the color preferred by the user may be displayed.

以下に、複数台のモニタの色を合せる手順の例を、図1のフローチャートに従って、説明する。   Hereinafter, an example of a procedure for matching the colors of a plurality of monitors will be described with reference to the flowchart of FIG.

S (STEP) 6;
By comparing the color of the image data displayed on the color adjustment target monitor with the color of the image data displayed on the reference monitor with the human eye, the color of the color adjustment target monitor is matched with the reference monitor. Then, it returns to STEP1.

以下に、正しい色特性を持つモニタが1つも無いときに、1つのモニタを選択して、選択した1つのモニタを、正しい色特性を持つモニタにする方法の例を、2つ挙げる。   Below, there are two examples of a method of selecting one monitor when there is no monitor having the correct color characteristics and making the selected monitor have a monitor having the correct color characteristics.

第1の例では、色調整対象のモニタに表示された画像データの色と、印刷物に印刷されている画像データの色とを人の目で比較することにより、色調節対象のモニタの色を、印刷物の色に合わせる任意の公知の技術を、選択した1つのモニタに適用して、選択した1つのモニタを、印刷物の色に合わせる。この例では、正しい色特性を持つモニタとは、印刷物と同じ色を表示するモニタのことである。   In the first example, by comparing the color of the image data displayed on the color adjustment target monitor and the color of the image data printed on the printed material with the human eye, the color of the color adjustment target monitor is changed. Any known technique for matching the color of the printed material is applied to the single selected monitor to match the single selected monitor to the color of the printed material. In this example, the monitor having the correct color characteristics is a monitor that displays the same color as the printed material.

第2の例では、選択した1つのモニタで、何か画像データを表示し、ユーザが好む色を表示するように、このモニタの色を調整する。この例では、正しい色特性を持つモニタとは、ユーザの好む色を表示するモニタのことである。ここで使用する画像データは、ユーザが持っている画像データであっても良い。ここでの具体的な色調整方法は、表示するRGB値をそれぞれR値、G値、B値に対して大きさを変更することにより、表示するモニタの色を変更する。例えば、全体的に「赤く」「青く」というように変更を行う。   In the second example, the color of this monitor is adjusted so that some image data is displayed on the selected monitor and the color preferred by the user is displayed. In this example, a monitor having correct color characteristics is a monitor that displays a color preferred by the user. The image data used here may be image data possessed by the user. The specific color adjustment method here changes the color of the monitor to be displayed by changing the RGB values to be displayed with respect to the R value, the G value, and the B value, respectively. For example, the change is made as “red” or “blue” as a whole.
