Description

その数値と発色との整合性は、たとえば反射色のＨＶ／Ｃ検索モードでも証明可能になる。
図７は、図４のライトボックスを用いＤ６５照明において、モニタ発色部のＹを併置させた無彩色の反射率と等しくなるように厳密に本体較正（キャリブレーション）した後、スマホ本体５０のモニタ発色部５１に実物のマンセル色票片を隣接させ、マンセル色票の裏に印刷されているマンセル記号のＨＶ／Ｃ、５３では１０ＹＲ８／１４、５５では７．５Ｒ５／１６、５６では１０ＢＧ７／８，１０ＧＹ６／１２をＨＶ／Ｃ入力スライダー５４により入力したもので、図に代えた写真が示すように、光源はＤ６５においてＣ光源モードでありながらその発色は色票と驚くほど一致する。このように反射色の場合もその等色状態は驚異的整合性を示し、いかに正確な色数値化と色検証が可能になるかがわかる。
なお、較正時に、演色性の優れた光源で、任意測定色に近似する標準色票を較正基準として用いて厳密に等色させれば、ほとんどの場合に等色するが、ごく僅かな色相（Ｈ）ズレが生じる場合もあるが、その場合は、そのまま等色させて当然生じる標準との等色誤差（色ズレのプラマイ値））を見出して数値修正（たとえば５Ｙ色票が＋２の７Ｙで等色する場合は測定Ｙ値から２をマイナス）すれば適正測定値を求めことができ、あるいは光源側に（その色ズレがＧ方向であれば１０Ｍといった）色ズレとは補色系の補正フィルターを用いて等色させることによって、これまで史上、まったく不可能であった、視感弁別可能７５０万全色の完全等色による厳密色数値化と色検証化を可能にする。
そして、上記フィルター補正法は、従来演色性に難点のあるＬＥＤ光源を、有効に超高演色性標準光源として実用化可能にできる効果を生む。つまり、これまでは「演色性評価数計算用試験色」（ＪＩＳＺ８７２６付表）の全色に対して完全等色しない光源も、その評価数の低い（完全等色しない）各色彩系に対して等色度を向上させる特定の演色性補正フィルター（上記Ｙ系列ではＭフィルター）を光源前面で着脱自在とすることにより、全色に対して従来不能の完全等色を可能にする新しい標準光源システムを供給可能にして、これまでの比色判定法、色評価法の判定精度を著しくレベルアップすることが可能になる。判定する色相に応じてフィルター選択が必要になるが、演色性に欠点のない新しい標準光源システムが可能になるということである。
なお、較正では図７のようにモニタ発色部５１に標準色票５２等を隣接させて等色をおこなう以外、本発明ではカメラのズーミング機能による拡大等色ができる。したがって、たとえば印刷色判定などでは図１１の７５のように発色部にオーバーラップ、あるいはφ５にパンチングして完全等色させれば発色部が一様に一色に見えるので等色がきわめて容易迅速、確実にでき、その発色部をカメラ拡大すればゴマ粒サイズやまたカレー粉やコーヒー等の粉末色も容易に等色可能になる。
そしてその場合、発色部（図７の５１，図８の１）の面積をその右側にある白色部（透過色判定位置）３をも含めて倍増することができ、あるいはｏｐ（オプション）ボタン切り換えによってモニタ画面全体を発色部とし、撮影用カメラでその発色のデータ操作を可能にすることにより、これまでは測れなかったシクラメンや黄色の小さな花ビラなどの高彩度色も容易に完全等色でき、形状、質感ととともに、ミリ単位の目盛の表示により、被測定物の正確な大きさも判明し、これまでまさに不能であった被測定物質の色数値化とともに画像記録による被測定物の厳密鑑識が可能となる。
同時に、標準色票にパンチ孔を設け較正操作の効率を向上させることが可能になるとともに打ち抜いた、φ５ミリサイズの打ち抜き片を透明フィルムに配して超小型の完全等色を可能にする安価でコンパクトな画期的標準色票集として供給可能になる。付け加えるならば、厳密数値はモニタが計算発色させるので、本発明の場合の較正用色票はＲ、ＹＲ、Ｙ、ＧＹ、Ｇ、ＢＧ、Ｂ、ＰＢ、Ｐ、ＲＰの１０色相の高彩度、中彩度色の２０色票で十分に可視弁別色７５０万に匹敵する無数の完全等色をその較正において可能とし、コンパクトな較正用基準で測色が手軽におこなえ、厳密測色の普及化に役立てることができる。
また、本発明における調光、調色のための等色操作は、標準色票や任意の試料色を用いて各入力モード（ＨＶ／Ｃ、ｘｙＹ、Ｌａｂ、ＨＶ／Ｃ、ＣＭＹ、ＲＧＢ）ごとに、若干の基礎知識と色感覚をもって試行錯誤しながら等色させるうちに熟達可能であるが、その調色技術の色合わせトレーニングをゲーム感覚でおこなえる「Ｇａｍｅ」モードを付加することによって熟達を早めることが可能になる。
その一実施例を示すと、モニタ画面の余白部分に「Ｇａｍｅ」ボタンを追加し、これを押すとＧａｍｅモードとなり白色部（３、透過色判定位置）に特定のあるいは任意の、色合わせのための「目標色」を番号順に現出可能とし、隣接する発色部（符号１）においてこれと等色可能という構成において、同一番号の選択によって同一の目標色との「所定時間内におけ等色度」や「等色までに要した時間」等をＲＧＢレベル差で他者と競合可能にすることにより、各モードの特性および各モード特有の調整法を熟達容易にしながらもっとも厳密な２５５ＲＧＢレベルでの調色トレーニングを楽しむと同時に調色能力テスターとして、また色彩教育の場での色彩学全般また各表色系の学習、そして調光、調色の実技訓練に大いに役立てることが可能になるとともに、このＧａｍｅモードをインターネットと接続することにより同時的色合わせオリンピックを開催し、世界最速、最強の色合わせチャンピオンの選出も可能になる。The consistency between the numerical value and the color development can be proved even in the reflection color HV / C search mode, for example.
FIG. 7 shows the monitor of the smartphone main body 50 after calibrating the main body strictly so as to be equal to the reflectance of the achromatic color in which Y of the monitor coloring portion is juxtaposed in the D65 illumination using the light box of FIG. The actual Munsell color chart piece is placed adjacent to the coloring section 51, and the Munsell symbol HV / C printed on the back of the Munsell color chart is 53, 10YR8 / 14, 55 is 7.5R5 / 16, 56 is 10BG7 / 8. , 10GY6 / 12 is input by the HV / C input slider 54, and as shown in the photograph in the figure, the light source is in the C light source mode at D65, and the color development surprisingly matches the color chart. In this way, even in the case of a reflected color, the color matching state shows an incredible consistency, and it can be seen how accurate color digitization and color verification are possible.
At the time of calibration, if a standard color chart that approximates an arbitrary measurement color is used as a calibration standard with a light source having excellent color rendering properties, it will be the same color in most cases, but a very slight hue ( H) Misalignment may occur, but in this case, the same color error from the standard (color misalignment plus value) that is naturally generated by finding the same color as it is is found, and numerical correction (for example, 5Y color chart is +2 7Y) In the case of equal colors, an appropriate measurement value can be obtained by subtracting 2 from the measured Y value, or a color misalignment on the light source side (such as 10M if the color misalignment is in the G direction) is a complementary color correction filter By using the color matching method, it is possible to perform strict color numerical value verification and color verification by completely equalizing all 7.5 million visual sensation distinguishable colors that has never been possible until now.
And the said filter correction method produces the effect which can make the LED light source which has a difficulty in conventional color rendering property effective as a super-high color rendering standard light source effectively. In other words, until now, light sources that do not completely equalize for all colors in the “color rendering index evaluation test color” (JIS Z 8726 appendix) can be used for each color system that has a low evaluation number (not completely equal). A new standard light source that enables unmatched color matching for all colors by making a specific color rendering correction filter (M filter in the above Y series) detachable on the front of the light source. The system can be supplied, and the determination accuracy of the conventional colorimetric determination method and the color evaluation method can be significantly increased. Depending on the hue to be determined, filter selection is required, but a new standard light source system that does not have a defect in color rendering is possible.
In the calibration, except that the standard color chart 52 and the like are adjacent to the monitor color developing unit 51 as shown in FIG. 7, the color can be enlarged by the zooming function of the camera in the present invention. Therefore, for example, in the determination of the print color, if the color development part overlaps the color development part as shown by 75 in FIG. If the color development part is enlarged by the camera, it is possible to easily match the sesame grain size and the powder color such as curry powder or coffee.
In that case, the area of the coloring portion (51 in FIG. 7 and 1 in FIG. 8) can be doubled including the white portion (transmission color judgment position) 3 on the right side, or the op (option) button is switched. By using the entire monitor screen as a color-developing part and enabling data manipulation of the color development with the camera for shooting, high-saturation colors such as cyclamen and small yellow leaflets that could not be measured can be easily and completely equalized. In addition to the shape and texture, the display of the scale in millimeters also reveals the exact size of the object to be measured. In addition to the quantification of the material to be measured, which has been impossible in the past, accurate identification of the object to be measured by image recording is possible. It becomes possible.
At the same time, it is possible to improve the efficiency of the calibration operation by providing punch holes in the standard color chart, and at the same time, a punched piece with a diameter of 5 mm is placed on a transparent film to enable ultra-compact complete color matching. It can be supplied as a compact and innovative standard color chart collection. In addition, since the accurate numerical values are calculated by the monitor, the color chart for calibration in the present invention is high saturation of 10 hues of R, YR, Y, GY, G, BG, B, PB, P, RP, medium With 20 color charts of chroma colors, innumerable completely equal colors comparable to the visible discrimination color of 7.5 million are possible in the calibration, and color measurement can be easily performed with a compact calibration standard, and the spread of strict color measurement Can be useful.
Further, the color matching operation for light adjustment and toning in the present invention is performed for each input mode (HV / C, xyY, Lab, HV / C, CMY, RGB) using a standard color chart or an arbitrary sample color. In addition, while it is possible to master while making the same color by trial and error with some basic knowledge and color sense, it is possible to advance mastery by adding a “Game” mode that allows color matching training of the toning technique to be done like a game It becomes possible.
In one embodiment, a “Game” button is added to the margin of the monitor screen, and when this button is pressed, the Game mode is entered, and the white portion (3, transparent color judgment position) is specific or arbitrary for color matching. In the configuration in which the “target colors” can be displayed in the order of numbers, and the same color can be equalized in the adjacent color forming unit (reference numeral 1), the same color within the predetermined time is selected by selecting the same number. By making it possible to compete with others by RGB level differences such as “degree” and “time required until equal colors”, etc., the characteristics of each mode and the adjustment method specific to each mode can be easily mastered at the most precise 255 RGB level. It can be used as a toning ability tester at the same time, and in addition to learning color in the color education field, studying each color system, and practical training in dimming and toning. With become, held a simultaneous color matching Olympic By connecting this Game mode with the Internet, the world's fastest, also made possible the election of the strongest color matching champion.
