Miscellaneous10/PhotoFiltre_Studio_X_10.3.0_Rus-1.jpg' alt='Photofiltre 6.4 0' title='Photofiltre 6.4 0' />JPEG compression is used in a number of image file formats. JPEGExif is the most common image format used by digital cameras and other photographic image capture devices along with JPEGJFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG. The term JPEG is an initialismacronym for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is imagejpeg, except in older Internet Explorer versions, which provides a MIME type of imagepjpeg when uploading JPEG images. JPEG files usually have a filename extension of. JPEGJFIF supports a maximum image size of 6. The JPEG standardeditJPEG stands for Joint Photographic Experts Group, the name of the committee that created the JPEG standard and also other still picture coding standards. The Joint stood for ISO TC9. WG8 and CCITT SGVIII. In 1. 98. 7 ISO TC 9. ISOIEC JTC1 and in 1. CCITT became ITU T. Currently on the JTC1 side JPEG is one of two sub groups of ISOIECJoint Technical Committee 1, Subcommittee 2. Working Group 1 ISOIEC JTC 1SC 2. WG 1  titled as Coding of still pictures. On the ITU T side ITU T SG1. The original JPE Group was organized in 1. JPEG standard in 1. September 1. 99. 2 as ITU T Recommendation T. ISOIEC 1. 09. 18 1. The JPEG standard specifies the codec, which defines how an image is compressed into a stream of bytes and decompressed back into an image, but not the file format used to contain that stream. The Exif and JFIF standards define the commonly used file formats for interchange of JPEG compressed images. JPEG standards are formally named as Information technology  Digital compression and coding of continuous tone still images.

Typical usageeditThe JPEG compression algorithm is at its best on photographs and paintings of realistic scenes with smooth variations of tone and color. For web usage, where reducing the amount of data used for an image is important for responsive presentation, JPEGs compression benefits make JPEG popular. JPEGExif is also the most common format saved by digital cameras. However, JPEG is not be as well suited for line drawings and other textual or iconic graphics, where the sharp contrasts between adjacent pixels can cause noticeable artifacts. Such images are better saved in a lossless graphics format such as TIFF, GIF, PNG, or a raw image format. The JPEG standard includes a lossless coding mode, but that mode is not supported in most products. As the typical use of JPEG is a lossy compression method, which reduces the image fidelity, it is inappropriate for exact reproduction of imaging data such as some scientific and medical imaging applications and certain technical image processing work. JPEG is also not well suited to files that will undergo multiple edits, as some image quality is lost each time the image is recompressed, particularly if the image is cropped or shifted, or if encoding parameters are changed  see digital generation loss for details. To prevent image information loss during sequential and repetitive editing, the first edit can be saved in a lossless format, subsequently edited in that format, then finally published as JPEG for distribution. JPEG compressioneditJPEG uses a lossy form of compression based on the discrete cosine transform DCT. This mathematical operation converts each framefield of the video source from the spatial 2. D domain into the frequency domain a. A perceptual model based loosely on the human psychovisual system discards high frequency information, i. In the transform domain, the process of reducing information is called quantization. In simpler terms, quantization is a method for optimally reducing a large number scale with different occurrences of each number into a smaller one, and the transform domain is a convenient representation of the image because the high frequency coefficients, which contribute less to the overall picture than other coefficients, are characteristically small values with high compressibility. The quantized coefficients are then sequenced and losslessly packed into the output bitstream. Nearly all software implementations of JPEG permit user control over the compression ratio as well as other optional parameters, allowing the user to trade off picture quality for smaller file size. In embedded applications such as mini. DV, which uses a similar DCT compression scheme, the parameters are pre selected and fixed for the application. The compression method is usually lossy, meaning that some original image information is lost and cannot be restored, possibly affecting image quality. There is an optional lossless mode defined in the JPEG standard. However, this mode is not widely supported in products. There is also an interlacedprogressive JPEG format, in which data is compressed in multiple passes of progressively higher detail.
