  <title>Brightness (Luminance)</title>
  <category>Camera</category>
  <description>Measure the luminance, i.e. the brightness observed through your camera's lens.

The resulting values use arbitraty units that are normalized to a fully white image with an ISO sensitivity of 100, aperture of f/1 and an exposure time of 1/60s. Phyphox will automatically scale the luminance calculated from the camera's image according to the current exposure settings. However, keep in mind that most phones take a moment to actually apply changing exposure settings, so if you use auto exposure or if you change the settings, it will take a moment for the readings to settle.

Also, the reading will be wrong and show saturation effects if any part of the image (or actually any color channel) is overexposed or (to a lesser extend) underexposed. Phyphox will highlight overexposed areas red and underexposed areas blue. You should avoid that read areas occur withint the measurement rectangle. Blue parts should be fine as long as they do not make up most of the measured area. The auto exposure mode in this configuration will try to avoid overexposure more aggressively than other parts of phyphox.

Further technical details: Phyphox uses the camera's preview stream and linearizes each pixel, assuming an sRGB color model with corresponding gamma curve. The resulting luminance is then averaged through a mix of shader-based averaging and texture filtering in the phone's GPU. However, non-linear behavior of cameras, especially if dynamic range compression is applied even in the preview, is beyond our control and might impact measurements on some phone models.

      <title>Helligkeit (Leuchtdichte)</title>
      <category>Kamera</category>
      <description>Miss die Leuchtdichte, also die Helligkeit durch die Optik der Kamera.

Das Ergebnis wird in beliebigen Einheiten angegeben, die auf ein rein weißes Bild bei ISO-Empfindlichkeit von 100, einer Blende von f/1 und einer Belichtungsdauer von 1/60s normiert ist. Phyphox skaliert den aus dem Kamerabild errechneten Wert automatisch unter Berücksichtigung der aktuellen Belichtungseinstellungen. Du solltest allerdings beachten, dass die meisten Handys einen Moment benötigen um geänderte Belichtungseinstlelungen anzuwenden, so dass es beim Ändern der Werte oder bei Benutzung der automatischen Belichtung einen Moment dauert bis die Werte stabil sind.

Zudem wird die Messung verfälscht und zeigt Sättigungseffekte sobald irgendein Teil des Bilds (oder sogar nur ein Farbkanal) überbelichtet oder (mit schwächeren Folgen) unterbelichtet ist. Phyphox wird überbelichtete Bereiche rot und unterbelichtete blau markieren. Du solltest unbedingt vermeiden, dass rote Bereiche in Mess-Rechteck ercheinen. Blaue Bereiche sind in Ordnung, solange sie nicht den Großteil der Messung ausmachen. Die automatische Belichtung in dieser Konfiguration wird deutlich aggressiver versuchen Überbelichtungen zu vermeiden als in anderen phyphox-Konfigurationen.

Weitere technische Details: Phyphox nutzt den Vorschau-Stream der Kamera und linearisiert jeden Pixel unter der Annahme, dass es sich um Daten im sRGB Farbmodell handelt mit der entsprechenden Gamma-Kurve. Die resultierende Leuchtdichte wird dann über eine Mischung aus Shader-basierter Mittelung und linearer Textur-Interpolation in der Grafikeinheit des Handys gemittelt. Allerdings liegen nicht-lineares Verhalten von Kameras, insbesondere wenn auch in der Vorschau Dynamikkompression angewendet wird, außerhalb unserer Kontrolle und können auf manschen Geräten die Messung negativ beeinflussen.

Dies geschieht, wenn Details im Bild durch extreme Helligkeitswerte verloren gehen würden. Bei Smartphones mit starker Dynamikbereichskompression bleibt die relative Leuchtdichte nahezu unverändert, selbst wenn die Kameraeinstellungen verändert werden, da das bearbeitete Bild eine ähnliche Helligkeit beibehält.</string>

      <string original="How to measure reliably despite post-processing?">Wie kann man trotz Nachbearbeitung zuverlässig messen?</string>
      <string original="We recommend to keep the exposure such that the measured area is at medium brightness (i.e. gray). The auto exposure from phyphox will adapt the camrea settings to achieve this and this brightness level is mostly unaffected by the post-processing of your phone. The relative luminance is then almost entirely based on the camera settings (especially ISO and exposure time) that are required to achieve this brightness. However, the auto exposure takes a moment to settle, so you should wait a moment before taking relative luminance measure and observe if the preview image settles in a medium gray brightness.">Wir empfehlen, die Belichtung so einzustellen, dass der gemessene Bereich eine mittlere Helligkeit (d.h. grau) aufweist. Die automatische Belichtung von phyphox passt die Kameraeinstellungen entsprechend an, sodass dieser Helligkeitsbereich erreicht wird.

Die relative Leuchtdichte basiert dann fast ausschließlich auf den Kameraeinstellungen (insbesondere ISO und Belichtungszeit), die für diese Helligkeit erforderlich sind.

      <string original="The raw data from the camera is converted to RGB and the individual RGB channels are linearized assuming the gamma curve of sRGB, and then converted to luma.

      <description>Μετρήστε τη λαμπρότητα μέσω του φακού της φωτογραφικής σας μηχανής.

Οι τιμές είναι σε αυθαίρετες μονάδες που κανονικοποιούνται σε μια πλήρως λευκή εικόνα με ευαισθησία ISO 100, διάφραγμα f/1 και χρόνο έκθεσης 1/60s. Το Phyphox θα κλιμακώσει αυτόματα τη λαμπρότητα που υπολογίζεται από την εικόνα της φωτογραφικής μηχανής σύμφωνα με τις τρέχουσες ρυθμίσεις έκθεσης. Ωστόσο, να έχετε υπόψη σας ότι τα περισσότερα τηλέφωνα χρειάζονται κάποιο χρόνο για να εφαρμόσουν πραγματικά την αλλαγή των ρυθμίσεων έκθεσης, οπότε αν χρησιμοποιείτε την αυτόματη έκθεση ή αν αλλάξετε τις ρυθμίσεις, θα χρειαστεί κάποιος χρόνος για να σταθεροποιηθούν οι μετρήσεις.

Επίσης, η ένδειξη θα είναι λανθασμένη και θα εμφανίζει φαινόμενα κορεσμού αν οποιοδήποτε μέρος της εικόνας (ή στην πραγματικότητα οποιοδήποτε κανάλι χρώματος) είναι υπερεκτεθειμένο ή (σε μικρότερο βαθμό) υποεκτεθειμένο. Το Phyphox θα επισημάνει τις υπερεκτεθειμένες περιοχές με κόκκινο χρώμα και τις υποεκτεθειμένες περιοχές με μπλε χρώμα. Θα πρέπει να αποφεύγετε να εμφανίζονται κόκκινες περιοχές εντός του ορθογωνίου μέτρησης. Η εμφάνιση μπλε περιοχών δεν δημιουργεί πρόβλημα, εφόσον δεν αποτελούν το μεγαλύτερο μέρος της μετρούμενης περιοχής. Η λειτουργία αυτόματης έκθεσης σε αυτή τη διαμόρφωση θα προσπαθήσει να αποφύγει την υπερέκθεση πιο έντονα από άλλα μέρη του phyphox.

Περαιτέρω τεχνικές λεπτομέρειες: Το Phyphox χρησιμοποιεί την προεπισκόπηση της φωτογραφικής μηχανής και γραμμικοποιεί κάθε εικονοστοιχείο, χρησιμοποιώντας ένα χρωματικό μοντέλο sRGB με την αντίστοιχη καμπύλη γάμμα. Στη συνέχεια, η προκύπτουσα φωτεινότητα υπολογίζεται κατά μέσο όρο μέσω ενός συνδυασμού μέσου όρου που βασίζεται σε shader και φιλτραρίσματος υφής στην GPU του τηλεφώνου. Ωστόσο, η μη γραμμική συμπεριφορά των φωτογραφικών μηχανών, ειδικά αν εφαρμόζεται συμπίεση δυναμικού εύρους ακόμη και στην προεπισκόπηση, είναι εκτός του ελέγχου μας και ενδέχεται να επηρεάσει τις μετρήσεις σε ορισμένα μοντέλα τηλεφώνων.

Η αυτόματη έκθεση από το phyphox θα προσαρμόσει τις ρυθμίσεις της κάμερας για να επιτευχθεί αυτό. Τότε το επίπεδο φωτεινότητας δεν επηρεάζεται σχεδόν καθόλου από την επεξεργασία μετά τη λήψη του τηλεφώνου σας. Η σχετική φωτεινότητα βασίζεται σχεδόν εξ ολοκλήρου στις ρυθμίσεις της κάμερας (ειδικά στο ISO και τον χρόνο έκθεσης) που απαιτούνται για την επίτευξη αυτής της φωτεινότητας. Ωστόσο, η αυτόματη έκθεση χρειάζεται λίγο χρόνο για να σταθεροποιηθεί, οπότε θα πρέπει να περιμένετε λίγο πριν μετρήσετε τη σχετική φωτεινότητα παρατηρώντας αν η εικόνα προεπισκόπησης σταθεροποιείται σε μέτρια γκρι φωτεινότητα.</string>

      <title>Jasność (luminancja)</title>

      <description>Zmierz luminancję, czyli jasność obserwowaną przez obiektyw aparatu w telefonie.

Otrzymane wartości wyrażone są w jednostkach umownych, znormalizowanych do w pełni białego obrazu przy czułości ISO 100, przysłonie f/1 oraz czasie naświetlania 1/60 s. Aplikacja Phyphox automatycznie skaluje luminancję obliczaną na podstawie obrazu z kamery zgodnie z aktualnymi ustawieniami ekspozycji. Należy jednak pamiętać, że większość telefonów potrzebuje chwili na faktyczne zastosowanie zmienionych ustawień ekspozycji, dlatego przy korzystaniu z automatycznej ekspozycji lub przy ręcznej zmianie ustawień odczyty stabilizują się z pewnym opóźnieniem.

Odczyty będą również niepoprawne i mogą wykazywać efekty nasycenia, jeśli jakakolwiek część obrazu (a w praktyce dowolny kanał kolorów) jest prześwietlona lub — w mniejszym stopniu — niedoświetlona. Phyphox zaznacza obszary prześwietlone kolorem czerwonym, a obszary niedoświetlone kolorem niebieskim. Należy unikać sytuacji, w których w prostokącie pomiarowym pojawiają się czerwone obszary. Niebieskie obszary są dopuszczalne, o ile nie stanowią większości mierzonego obszaru. Tryb automatycznej ekspozycji w tej konfiguracji stara się unikać prześwietleń bardziej agresywnie niż w innych częściach aplikacji.

Dodatkowe informacje techniczne: aplikacja Phyphox korzysta ze strumienia podglądu kamery i linearyzuje każdy piksel, zakładając model barw RGB wraz z odpowiadającą mu krzywą gamma. Następnie uzyskana luminancja jest uśredniana przy użyciu kombinacji uśredniania realizowanego w shaderach oraz filtrowania tekstur w procesorze graficznym (GPU) telefonu. Nieliniowe zachowanie kamer — szczególnie w przypadkach, gdy nawet w trybie podglądu stosowana jest kompresja zakresu dynamicznego — pozostaje poza naszą kontrolą i może wpływać na wyniki pomiarów w niektórych modelach telefonów.

      <title>亮度 (辉度)</title>
      <category>相机</category>
      <description>测量通过相机镜头观测到的亮度。

所得数值采用相对单位，并以 ISO 感光度 100、光圈 f/1、曝光时间 1/60 秒下的纯白图像为基准进行了归一化处理。Phyphox 会根据当前的曝光设置，自动对从相机图像计算出的亮度值进行缩放调整。请注意，大多数手机在应用新的曝光设置时会有一定的延迟；因此，若使用自动曝光或手动更改设置，读数需要片刻时间才能稳定下来。

此外，如果图像的任何部分（或具体到任一颜色通道）出现过曝或（程度较轻的）欠曝，读数将会出现偏差并显示饱和效应。Phyphox 会以红色高亮显示过曝区域，以蓝色高亮显示欠曝区域。应避免在测量矩形框内出现红色区域。蓝色区域通常无碍，只要它们不占据测量区域的大部分即可。在此配置下，自动曝光模式会比 Phyphox 的其他功能模块更积极地避免过曝。

更多技术细节：Phyphox 利用相机的预览数据流，并基于 sRGB 色彩模型及其对应的伽马曲线对每个像素进行线性化处理。随后，系统利用手机 GPU 中的着色器（shader）平均算法与纹理过滤技术，计算出平均亮度值。然而，相机的非线性特性（尤其是当预览画面已应用动态范围压缩时）超出了我们的控制范围，这可能会影响某些机型上的测量结果。

      <description>લ્યુમિનન્સ માપો, એટલે કે તમારા કેમેરાના લેન્સ દ્વારા જોવા મળતી બ્રાઈટનેસ.

પરિણામી મૂલ્યો આર્બિટ્રેટી એકમોનો ઉપયોગ કરે છે જે 100 ની ISO સંવેદનશીલતા, f/1 નું અપર્ચર અને 1/60 ના એક્સપોઝર સમય સાથે સંપૂર્ણપણે સફેદ છબી માટે સામાન્ય બને છે. Phyphox વર્તમાન એક્સપોઝર સેટિંગ્સ અનુસાર કેમેરાની છબીમાંથી ગણતરી કરાયેલ લ્યુમિનન્સને આપમેળે માપશે. જો કે, ધ્યાનમાં રાખો કે મોટાભાગના ફોન બદલાતા એક્સપોઝર સેટિંગ્સ લાગુ કરવામાં થોડો સમય લે છે, તેથી જો તમે ઓટો એક્સપોઝરનો ઉપયોગ કરો છો અથવા જો તમે સેટિંગ્સ બદલો છો, તો રીડિંગ્સ સેટ થવામાં થોડો સમય લાગશે.

ઉપરાંત, જો છબીનો કોઈપણ ભાગ (અથવા ખરેખર કોઈપણ રંગ ચેનલ) વધુ પડતું એક્સપોઝર અથવા (ઓછા પ્રમાણમાં) ઓછું એક્સપોઝર હોય તો વાંચન ખોટું હશે અને સેચ્યુરેશન અસરો બતાવશે. Phyphox વધુ પડતા એક્સપોઝરવાળા વિસ્તારોને લાલ અને ઓછા એક્સપોઝરવાળા વિસ્તારોને વાદળી રંગમાં પ્રકાશિત કરશે. તમારે માપન લંબચોરસમાં વાંચન વિસ્તારો ન આવે તે ટાળવું જોઈએ. વાદળી ભાગો બરાબર હોવા જોઈએ જ્યાં સુધી તેઓ માપેલા વિસ્તારનો મોટાભાગનો ભાગ ન બનાવે. આ રૂપરેખાંકનમાં ઓટો એક્સપોઝર મોડ Phyphoxના અન્ય ભાગો કરતાં વધુ આક્રમક રીતે ઓવરએક્સપોઝર ટાળવાનો પ્રયાસ કરશે.

વધુ તકનીકી વિગતો: Phyphox કેમેરાના પ્રીવ્યૂ સ્ટ્રીમનો ઉપયોગ કરે છે અને દરેક પિક્સેલને રેખીય બનાવે છે, અનુરૂપ ગામા કર્વ સાથે sRGB કલર મોડેલ ધારે છે. પરિણામી લ્યુમિનન્સ પછી ફોનના GPU માં શેડર-આધારિત સરેરાશ અને ટેક્સચર ફિલ્ટરિંગના મિશ્રણ દ્વારા સરેરાશ કરવામાં આવે છે. જો કે, કેમેરાનું બિન-રેખીય વર્તન, ખાસ કરીને જો પ્રીવ્યૂમાં પણ ડાયનેમિક રેન્જ કમ્પ્રેશન લાગુ કરવામાં આવે તો, તે અમારા નિયંત્રણની બહાર છે અને કેટલાક ફોન મોડેલો પર માપને અસર કરી શકે છે.

      <title>밝기 (휘도)</title>
      <category>카메라</category>
      <description>휘도, 즉 카메라 렌즈를 통해 관찰되는 밝기를 측정합니다.

결과 값은 ISO 감도 100, 조리개 f/1, 노출 시간 1/60초 조건의 완전한 흰색 이미지로 정규화된 임의 단위를 사용합니다. Phyphox는 현재 노출 설정에 따라 카메라 이미지에서 계산된 휘도를 자동으로 스케일링합니다. 다만 대부분의 휴대폰은 변경된 노출 설정을 실제로 적용하는 데 약간의 시간이 걸리므로, 자동 노출을 사용하거나 설정을 변경하면 측정값이 안정화되기까지 잠시 시간이 걸립니다.

또한 이미지의 어느 한 부분(또는 특정 색상 채널)이 노출 과다이거나 노출 부족인 경우 측정값이 잘못되고 포화(saturation) 현상이 나타납니다. Phyphox는 노출 과다 영역을 빨간색으로, 노출 부족 영역을 파란색으로 강조합니다. 측정 사각형 내에 빨간색 영역이 발생하는 것은 피해야 합니다. 파란색 부분은 측정 영역의 대부분을 차지하지 않는 한 괜찮습니다. 이 구성의 자동 노출 모드는 phyphox의 다른 부분보다 노출 과다를 더 적극적으로 방지하려고 시도합니다.

추가 기술 상세: phyphox는 카메라의 미리보기 스트림을 사용하고 해당 감마 곡선이 있는 sRGB 색상 모델을 가정하여 각 픽셀을 선형화합니다. 그런 다음 결과 휘도는 휴대폰 GPU에서 셰이더 기반 평균화와 텍스처 필터링의 조합을 통해 평균화됩니다. 그러나 카메라의 비선형 동작, 특히 미리보기 단계에서조차 동적 범위 압축(DRC)이 적용되는 경우는 제어 범위를 벗어나며 일부 휴대폰 모델의 측정에 영향을 줄 수 있습니다.
