Jpeg - joint photographic experts group
| Глоссарий терминов по видеокамерам |
Jpeg joint photographic experts group the name of the committee that designed the standard image compression algorithm. jpeg is designed for compressing either full-color or grey-scale digital images of natural, real-world scenes. it does not work so well on non-realistic images, such as cartoons or line drawings. jpeg does not handle compression of black-and-white (1 bit-per-pixel) images or moving pictures. see jpg below. jpeg2000 the new jpeg compression standard that will be used in digital cameras and software starting in 2002 (maybe?). it will feature higher compression but with less image quality loss.

Photographic, английский
Compression, английский
- A state or condition of being pushed or shortened by a force.
- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull
- Смыкание (губок захватного устройства) cm. соmрutеr-соntrоllеd rоbоt 33. соntinuоus-раth mоtiоn движение робота по полностью программируемой траектории (при котором полная траектория, описываемая рукой манипулятора, программируется на программоноситель во время обучения так, чтобы каждая точка вдоль траектории движения регистрировалась для дальнейшего воспроизведения)
- Сжатие (данных); уплотнение; свертка; компрессия; упаковка
- Жёсткость (стержня) при сжатии; ~ in tension жёсткость (стержня) при растяжении; ~ in
- Продольно-поперечный изгиб, поперечный изгиб со сжатием; ~ and axial tension изгиб с осевым растяжением; ~ in two planes косой изгиб ~ of rebars [of reinforcing bars] гибка арматурных стержней beam ~ изгиб балки
- Сжатие о ~ along the grain сжатие вдоль волокон; ~ beyond
- Сжатое волокно; ~ in
- The intentional reduction in dynamic range to increase sustain and/or add punchiness, caused by a the use of a compressor/limiter.
- A process for removing redundant data from a digital media file or stream to reduce its size or the bandwidth used.
- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.
Compressing, английский

Jpg, английский
- The most common type of compressed image file format used in digicams. it is a lossy type of storage because even in its highest quality mode there is compression used to minimize its size. see the official jpeg home page for even more details
- This is the most common type of compressed image file format used in modern digicams. it is a “lossy” type of image storage because even in its highest quality mode, there is compression used to minimize its size.
- Jpg file type extension or jpeg - "joint photographic experts group" - is one of several digital image formats that are viewable in web browsers. jpeg image files are encoded using a standard for file compression (making the files smaller) that preserves essential color and display information in a fairly photorealistic way, with smooth edges, shapes and color blends. jpeg files are generally preferred for displaying still image photographs in digital form. the jpeg format is "lossy," meaning some information is lost when an image is compressed. this accounts for the "fuzziness" and patchy color areas what you may see when lower resolution jpeg images are enlarged to fill a space on the screen.
Jaggies, английский
- Slang term for the stair-stepped appearance of a curved or angled line in digital imaging. the smaller the pixels, and the greater their number the less apparent the jaggies. also known as pixelization.
- Term for the stair-stepped appearance of curved or angled lines in a digital image file. the smaller the pixels and/or the greater their number, the less apparent are the “jaggies.” jaggies are most common in photographs captured at lower resolving powers and hello kitty-type digital cameras.
