(ar) HSV (Hue, Saturation, Value), také známý jako HSB (Hue, Saturation, Brightness), je barevný model, který vytvořil v roce 1978 . Tento barevný model nejvíce odpovídá lidskému vnímání barev. Skládá se ze tří složek (nejsou to základní barvy), u nichž je nutno hlídat hodnoty (možné nesmyslné kombinace): * Hue – odstín. Převládající barva odražená nebo procházející objektem. Měří se jako poloha na standardním barevném kole (0° až 360°). Obecně se odstín označuje názvem barvy. * Saturation – sytost barvy, příměs jiné barvy. Někdy též chroma, síla nebo čistota barvy, představuje množství šedi v poměru k odstínu, měří se v procentech od 0 % (šedá) do 100 % (plně sytá barva). Na barevném kole vzrůstá sytost od středu k okrajům. Např. červená s 50 % sytostí bude růžová. * Value – hodnota jasu, množství bílého světla. Relativní světlost nebo tmavost barvy. Jas vyjadřuje kolik světla barva odráží, dalo by se také říct přidávání černé do základní barvy. (cs) La HSV-kolorsistemo estas sistemo de pluraj komputikaj kolormodeloj: en ili la koloro difiniĝas pere de la kolornuanco (angle hue), la kolorintenseco (saturation) kaj la heleca respektive malheleca valoro (value). Similaj difinoj gvidas al HSL-kolorsistemo kun relativa heleco (lightness), al HSB-kolorsistemo kun absoluta heleco (brightness) kaj al HSI-kolorsistemo kun lumintenseco (intensity). (eo) Der HSV-Farbraum ist der Farbraum etlicher Farbmodelle. Hier ist der Farbort einer Farbe definiert mit Hilfe der drei Koordinaten: * Farbwert (englisch hue): Farbwinkel auf dem Farbkreis (0° für Rot, 120° für Grün, 240° für Blau) * Farbsättigung (saturation): (0% = Neutralgrau, 50% = wenig gesättigte Farbe, 100% = gesättigte, reine Farbe) * Hellwert (value; auch Dunkelstufe genannt): (0% = keine Helligkeit, 100% = volle Helligkeit) Ähnliche Definitionen führen zu * einem HSL-Farbraum mit der relativen Helligkeit (lightness) statt des Hellwertes * einem HSB-Farbraum mit der absoluten Helligkeit (brightness) * einem HSI-Farbraum mit der Lichtintensität (intensity). (de) HSL (for hue, saturation, lightness) and HSV (for hue, saturation, value; also known as HSB, for hue, saturation, brightness) are alternative representations of the RGB color model, designed in the 1970s by computer graphics researchers to more closely align with the way human vision perceives color-making attributes. In these models, colors of each hue are arranged in a radial slice, around a central axis of neutral colors which ranges from black at the bottom to white at the top. The HSL representation models the way different paints mix together to create color in the real world, with the lightness dimension resembling the varying amounts of black or white paint in the mixture (e.g. to create "light red", a red pigment can be mixed with white paint; this white paint corresponds to a high "lightness" value in the HSL representation). Fully saturated colors are placed around a circle at a lightness value of ½, with a lightness value of 0 or 1 corresponding to fully black or white, respectively. Meanwhile, the HSV representation models how colors appear under light. The difference between HSL and HSV is that a color with maximum lightness in HSL is pure white, but a color with maximum value/brightness in HSV is analogous to shining a white light on a colored object (e.g. shining a bright white light on a red object causes the object to still appear red, just brighter and more intense, while shining a dim light on a red object causes the object to appear darker and less bright). The issue with both HSV and HSL is that these approaches do not effectively separate color into their three value components according to human perception of color. This can be seen when the saturation settings are altered — it is quite easy to notice the difference in perceptual lightness despite the "V" or "L" setting being fixed. (en) Teinte, saturation, luminosité (ou valeur) sont les trois paramètres de description d'une couleur dans une approche psychologique de cette perception. Cette expression désigne des modèles de description des couleurs utilisés en graphisme informatique et en infographie, qui adaptent ces paramètres. Les sigles TSL ou, en anglais HSL ((en) Hue, Saturation, Lightness) désignent de tels systèmes de description des couleurs. La luminosité étant à peu près ce qu'on appelle la valeur ((en) Value), TSV ou HSV s'utilisent pour différencier des systèmes basés sur les mêmes principes, avec une mise en œuvre différente. De nombreux logiciels de retouche et de création graphiques matricielle offrent une interface de description des couleurs Teinte, Saturation, Luminosité. Dans ce cas, les couleurs sont toujours enregistrées comme composantes trichromes (rouge, vert, bleu). Dans les logiciels d'édition d'image vectorielle, les paramètres de Teinte, saturation, luminosité peuvent servir de définition de la couleur et être enregistrés. Le W3C a adopté cette description perceptuelle, en parallèle avec les descriptions trichromes, pour définir les couleurs, au format texte, dans les feuilles de style en cascade et les dessins vectoriels SVG. (fr) HSL (hue, saturation, lightness) dan HSV (hue, saturation, value) adalah dua representasi alternatif dari model warna RGB yang dirancang pada tahun 1970-an oleh peneliti grafika komputer untuk lebih menyelaraskannya dengan cara membuat atribut penglihatan manusia yang memandang warna. Dalam model ini, warna dari masing-masing hue diatur dalam irisan radial, sekitar poros tengah dari warna-warna netral yang berkisar hitam di bagian bawah untuk di bagian putih atas. HSV memodelkan representasi dengan cara mencampurkan cat dari berbagai warna bersama-sama dengan saturasi dimensi menyerupai berbagai warna cerah cat berwarna dan nilai dimensi yang menyerupai campuran cat-cat dengan jumlah yang bervariasi dari cat hitam atau putih. Upaya model HSL untuk lebih menyerupai persepsi warna model seperti atau Munsell menempatkan sepenuhnya warna jenuh di sekitar lingkaran di lightness nilai , di mana nilailightness 0 atau 1 adalah sepenuhnya hitam atau putih, masing-masing. Ruang warna HSL diciptakan pada tahun 1938 oleh sebagai cara untuk menambah penyandian warna pada siaran monokrom yang telah ada (yaitu yang hanya mengandung sinyal L) yang memungkinkan ada penerima untuk menerima warna siaran baru (hitam dan putih) tanpa modifikasi seperti sinyal siaran Luminansi (hitam dan putih) yang tidak dimodifikasi. HSL telah digunakan dalam penyandian semua siaran analog utama televisi termasuk NTSC, PAL, dan SECAM dan semua sistem siaran digital dan merupakan dasar untuk . (in) Hue Saturation Brightness (HSB), in inglese "tonalità, saturazione e luminosità", indica sia un metodo additivo di composizione dei colori, sia un modo per rappresentarli in un sistema digitale. Viene anche chiamato HSV da Hue Saturation Value (tonalità, saturazione e valore) o HSI da Hue Saturation Intensity (tonalità, saturazione ed intensità). È una variante del modello Hue Saturation Lightness (HSL). (it) HSL和HSV都是一种将RGB色彩模型中的点在圆柱坐标系中的表示法。这两种表示法试图做到比基于笛卡尔坐标系的几何结构RGB更加直观。 HSL即色相、饱和度、亮度（英語：Hue, Saturation, Lightness）。HSV即色相、饱和度、明度（英語：Hue, Saturation, Value），又称HSB，其中B即英語：Brightness。 * 色相（H）是色彩的基本属性，就是平常所说的颜色名称，如红色、黄色等。 * 饱和度（S）是指色彩的纯度，越高色彩越纯，低则逐渐变灰，取0-100%的数值。 * 明度（V），亮度（L），取0-100%。 HSL和HSV二者都把颜色描述在圓柱坐標系内的点，这个圆柱的中心轴取值为自底部的黑色到顶部的白色而在它们中间的是灰色，绕这个轴的角度对应于“色相”，到这个轴的距离对应于“饱和度”，而沿着这个轴的高度对应于“亮度”、“色调”或“明度”。 这两种表示在目的上类似，但在方法上有区别。二者在数学上都是圆柱，但HSV（色相、饱和度、明度）在概念上可以被认为是颜色的倒圆锥体（黑点在下顶点，白色在上底面圆心），HSL在概念上表示了一个双圆锥体和圆球体（白色在上顶点，黑色在下顶点，最大横切面的圆心是半程灰色）。注意尽管在HSL和HSV中“色相”指称相同的性质，它们的“饱和度”的定义是明显不同的。 因为HSL和HSV是设备依赖的RGB的简单变换，(h, s, l)或 (h, s, v)三元组定义的颜色依赖于所使用的特定红色、绿色和蓝色“加法原色”。每个独特的RGB设备都伴随着一个独特的HSL和HSV空间。但是 (h, s, l)或 (h, s, v)三元组在被约束于特定RGB空间比如sRGB的时候就更明确了。 HSV模型在1978年由埃爾維·雷·史密斯创立，它是三原色光模式的一种非线性变换，如果說RGB加色法是三維直角座標系，那麼HSV模型就是球面座標系。 (zh) |
