말뭉치

  1. The JPG image file type, typically pronounced jay-peg, was developed by the Joint Photographic Experts Group (JPEG) in 1992.[1]
  2. It offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency etc.[2]
  3. PNG is preferred over JPEG for more precise reproduction of source images, or when transparency is needed.[2]
  4. WebP offers much better compression than PNG or JPEG with support for higher color depths, animated frames, transparency etc.[2]
  5. The older formats like PNG, JPEG, GIF have poor performance compared to newer formats like WebP and AVIF, but enjoy broader "historical" browser support.[2]
  6. JPEG, which stands for Joint Photographic Experts Groups is a “lossy” format meaning that the image is compressed to make a smaller file.[3]
  7. JPEG (pronounced "jay-peg") is a standardized image compression mechanism.[4]
  8. JPEG stands for Joint Photographic Experts Group, the original name of the committee that wrote the standard.[4]
  9. JPEG compresses either full-color or grayscale images, and works best with photographs and artwork.[4]
  10. JPEG uses a lossy compression method, meaning that the decompressed image isn't quite the same as the original.[4]
  11. The topic of RAW vs JPEG image format is one of the never-ending debates in photography.[5]
  12. Some photographers say shoot in RAW, while others say shoot in JPEG.[5]
  13. What is the RAW format in digital photography and what are its advantages and disadvantages when compared to JPEG?[5]
  14. JPEG is a no-brainer – it’s the default image format that is used in most smartphones and point-and-shoot cameras, so we know what to expect from it.[5]
  15. A JPEG file is an image saved in a compressed graphic format standardized by the Joint Photographic Experts Group ( JPEG ).[6]
  16. In 1992, the workgroup created the JPEG file format.[6]
  17. JPEG files are images created using a lossy compression algorithm, which actually destroys some data contained within the original image file.[6]
  18. A JPEG file also contains metadata that describes the contents of its file, such as the color space, color profile, and image dimension information.[6]
  19. While converting some images to JPEG will result in a less crisp picture, the format is known for its ability to retain the best possible quality in the smallest possible file size.[7]
  20. While you don't have to be a computer whiz to convert an image to JPEG, you will need to learn a few tricks of the trade.[7]
  21. As a photographer you shoot in Raw or Jpeg, or sometimes both.[8]
  22. While there is a compression and loss of information editing jpeg images, the difference is so minor unless you are re-opening dozens of times.[8]
  23. JPEG files (compressed images) start with an image marker which always contains the marker code hex values FF D8 FF.[9]
  24. It does not have a length of the file embedded, thus we need to find JPEG trailer, which is FF D9.[9]
  25. Length is the size of the JFIF (APP0) marker segment, including the size of the Length field itself and any thumbnail data contained in the APP0 segment.[9]
  26. Version identifies the version of the JFIF specification, with the first byte containing the major revision number and the second byte containing the minor revision number.[9]
  27. JPEG is a lossy raster format that stands for Joint Photographic Experts Group, the technical team that developed it.[10]
  28. Do note that TIFF files can also be used as a “container” for JPEG images.[10]
  29. Typically, images are processed (adjusted for color, white balance, exposure, etc.) and then converted and compressed into another format (e.g. JPEG or TIFF).[10]
  30. JPEG stands for Joint Photographic Experts Group.[11]
  31. We also call JPEG the file format which employs this compression.[11]
  32. The JPEG committee has now created its own wavelet-based standard, JPEG 2000, which is intended to eventually supersede the original JPEG standard.[11]
  33. When you need to convert JPEG files to other formats like TIFF, PNG, BMP use Total Image Converter.[11]
  34. JPEG stands for Joint Photographic Experts Group, which is the name of the organisation that developed the image format.[12]
  35. Saving these kinds of graphics in JPEG often results in pixellation around the edges – when an image becomes blurry and you can see individual pixels.[12]
  36. These types of graphics won’t be as pixellated in PNG form as they would be as a JPEG.[12]
  37. As a result, images saved as GIFs are limited to just 256 colours, compared to around16 million possible colours in a JPEG image.[12]
  38. JPEG is a lossy format, Converting an image from other formats( e.g. PNG, BMP ) to JPEG format will cause quality loss.[13]
  39. int DEPTH_JPEG Depth augmented compressed JPEG format.[14]
  40. int JPEG Compressed JPEG format.[14]
  41. DEPTH_JPEG Added in API level 29 public static final int DEPTH_JPEG Depth augmented compressed JPEG format.[14]
  42. JPEG compressed main image along with XMP embedded depth metadata following ISO 16684-1:2011(E).[14]
  43. The procedure for compressing the digital images in JPEG format is carried out in several stages.[15]
  44. JPEG uses a "lossy" compression system and discrete cosine transform technology.[15]
  45. Use the PDF to JPEG converter to transform entire PDF pages into high-quality JPG images.[16]
  46. Some JPEG Image files use the .JPE file extension but that's not very common.[17]
  47. Some websites and programs might not recognize an image as a JPEG Image file unless it has the proper file extension that the program is looking for.[17]
  48. Both JPG and JPEG represent an image format supported by the Joint Photographic Experts Group and have the exact same meaning.[17]
  49. Like HTM and HTML files, when the JPEG format was first introduced, the official file extension was JPEG (with four letters).[17]
  50. We have already mentioned the format briefly in this article “ Graphic file formats – JPEG, PNG, SVG, PDF” .[18]
  51. However, JPEG is ideal for home photo storage, photo transmission through the Internet or posting on the site.[18]
  52. JPEG (Joint Photographic Experts Group) is an image compression format used for image files.[19]
  53. Since JPEG is compressed, it is a good image format to use for websites, allowing faster downloads.[19]
  54. JPEG requires an encoder that compresses the image format, whether it is from camera RAW or directly from an image processor.[19]
  55. Cameras can store a captured image directly to JPEG, depending on the settings.[19]
  56. JPEG (Joint Photographic Experts Group) refers to a standards organization, a method of file compression, and sometimes a file format.[20]
  57. The JPEG File Interchange Format (JFIF) is a development of C-Cube Microsystems for the purpose of storing JPEG-encoded data.[20]
  58. Both JPEG and JFIF data are byte streams, always storing 16-bit word values in big-endian format.[20]
  59. XThumbnail and YThumbnail give the dimensions of the thumbnail image included in the JFIF APP0 marker.[20]
  60. Most of the "Save" options will be greyed-out as the JPEG format can not hold extra features, such as Layers.[21]
  61. But in Photoshop, setting the JPEG quality level to "Maximum" can mean values of '10', '11' or '12'.[21]
  62. If you are working with older graphic programmes then note that some use a JPEG scale representing Compression rather than Quality.[21]
  63. The increase in JPEG compression does not come for free, though, as to achieve smaller sizes the JPEG file format removes increasing amounts of colour information from the pixels.[21]
  64. However, the JPEG lossy compression method can help to keep your visual files small, so that they load faster online.[22]
  65. The term “JPEG” can also refer to the Joint Photographic Experts Group, which is the name of the sub-committee responsible for building the JPEG image standard.[22]
  66. The JPEG format was issued by the International Organization for Standardization in 1992.[22]
  67. The JPEG format is the most common option used by digital cameras, and it supports 16,777,216 colors in total.[22]
  68. If you’ve ever moved photographs from a digital camera to a computer before, you’ll have encountered the JPEG (pronounced jay-peg) file format.[23]
  69. Digital cameras compress raw photographs as JPEG images to make the files smaller in size.[23]
  70. The JPEG file format was submitted and approved in 1992.[23]
  71. The higher frequency, more checkerboard-like, patterns have their respective weights lowered by an amount that depends on the JPEG quality setting.[23]
  72. JPEG is an abbreviated form of Joint Photographic Experts Group, the independent committee that created it as a standard for photography compression, which was approved in 1994 as ISO 10918-1.[24]
  73. The JPEG image file format has become popular for offering an amazingly effective compression method for color images.[24]
  74. It helps images to be compressed to about five percent of their original size, which allows for minimized traffic consumption for websites using JPEG images.[24]
  75. Generally, you can control the compression quality results by choosing from a range of compression algorithms when creating a JPEG file or converting an image from another format to JPEG.[24]
  76. The 16 million possible colors in a JPEG image are produced by using 8 bits for each color (red, green, and blue) in the RGB color space.[25]
  77. The JPEG compression algorithm may reduce the file size of a bitmap (BMP) image by ten times with almost no degradation in quality.[25]
  78. Besides image data, JPEG files may also include metadata that describes the contents of the file.[25]
  79. JPEG images also don't support transparency.[25]
  80. 2) JPEG (usually pronounced JAY-pehg) is also a term for any graphic image file produced by using a JPEG standard.[26]
  81. A JPEG file is created by choosing from a range of compression qualities (actually, from one of a suite of compression algorithms).[26]
  82. When you create a JPEG or convert an image from another format to a JPEG, you are asked to specify the quality of image you want.[26]
  83. Formally, the JPEG file format is specified in ISO standard 10918.[26]
  84. But what does JPEG stand for?[27]
  85. A JPEG is a type of image commonly found on the internet.[27]
  86. Most image programmes open JPEG files.[27]
  87. That’s because graphics like these typically have sharp contrast between the pixels, which can cause some graininess in the image if it’s saved as a JPEG.[27]
  88. It defines supplementary specifications for the container format that contains the image data encoded with the JPEG algorithm.[28]
  89. The base specifications for a JPEG container format is defined in the Annex B of the JPEG standard, known as JPEG Interchange Format (JIF).[28]
  90. JFIF builds over JIF to solve some of JIF's limitations, including unnecessary complexity, component sample registration, resolution, aspect ratio, and color space.[28]
  91. JPEG allows multiple components (such as Y, Cb, and Cr) to have different resolutions, but it does not define how those differing sample arrays should be aligned.[28]
  92. JPG (or JPEG), is a popular file format used for images and graphics—especially on the internet.[29]
  93. It was created by the Joint Photographic Experts Group (JPEG) and uses a compression algorithm that reduces sections of an image into blocks of pixels.[29]
  94. In the window that pops up, select JPEG as the format and use the “Quality” slider to change the compression used to save the image.[29]
  95. JPEG stands for “Joint Photographic Experts Group”.[30]
  96. Despite the huge reduction in file size JPEG images maintain reasonable image quality.[30]
  97. This unique compression feature allows JPEG files to be used widely on the Internet, Computers, and Mobile Devices.[30]
  98. Also, a large number of JPEG image files can be stored in minimum storage space.[30]
  99. , you should familiarize yourself with common file formats such as JPEG.[31]
  100. The first JPEG standard was issued in 1992 by ISO (International Organization for Standardization).[31]
  101. The last way the term JPEG is used is when referencing a file format name or a way to store and save digital images.[31]
  102. Remember when we discussed the term JPEG and how it stood for the Joint Photographic Experts Group?[31]
  103. The JPEG standard (ISO/IEC 10918) was created in 1992 (latest version, 1994) as the result of a process that started in 1986.[32]
  104. Part 1 of JPEG (ISO/IEC 10918-1 | ITU-T Recommendation T.81) specifies the core coding technology and it incorporates many options for encoding photographic images.[32]
  105. Part 4 focuses on the registration of JPEG profiles, SPIFF profiles, SPIFF tags, SPIFF color spaces, SPIFF compression types, and defines the Registration Authorities.[32]
  106. And lastly, Part 5 specifies the JPEG File Interchange Format (JFIF).[32]
  107. The term "JPEG" is an initialism/acronym for the Joint Photographic Experts Group, which created the standard in 1992.[33]
  108. JPEG compression is used in a number of image file formats.[33]
  109. The JPEG specification cites patents from several companies.[33]
