Blocked shadows
| Lens Glossary |
Term for lack of, or loss of, shadow detail in a photographic image, usually the result of underexposure or images captured by a lower resolution (and less dynamic) imaging sensor. although lost shadow detail can often be (partially) reclaimed in photo-editing applications, hdr (high dynamic range) imaging—in which two or more bracketed images are sampled and combined into a single image file containing increased levels of shadow, highlight, and mid-tone detail—has become an increasingly common in-camera solution for retaining both shadow and highlight detail.

- (in mechanics termed a pulley.) blocks are flattish oval pieces of wood, with sheaves in them, for all the running ropes to run in. they are used for various purposes in a ship, either to increase the mechanical power of the ropes, or to arrange the ends of them in certain places on the deck, that they may be readily found when wanted; they are consequently of various sizes and powers, and obtain various names, according to their form or situation, thus:—a single block contains only one sheave or wheel. a double block has two sheaves. a treble or threefold block, three, and so on. a long-tackle or fiddle-block has two sheaves—one below the other, like a fiddle. cistern or sister block for top-sail lifts and reef tackles. every block is composed of three, and generally four, parts:—(1.) the shell, or outside wooden part. (2.) the sheave, or wheel, on which the rope runs. (3.) the pin, or axle, on which the sheave turns. (4.) the strop, or part by which the block is made fast to any particular station, and is usually made either of rope or of iron. blocks are named and distinguished by the ropes which they carry, and the uses they serve for, as bowlines, braces, clue-lines, halliards, &c. &c. they are either made or morticed (which see).

Block (on the bitcoin blockchain), английский
Data is permanently recorded in the bitcoin network through files called blocks. a block is a record of some or all of the most recent bitcoin transactions that have not yet been recorded in any prior blocks. new blocks are added to the end of the record (known as the blockchain), and can never be changed or removed once written (although some software will remove them if they are orphaned). each block memorializes what took place in the minutes before it was created. each block contains a record of some or all recent transactions and a reference to the block that came immediately before it. it also contains an answer to a difficult-to-solve mathematical puzzle – the answer to which is unique to each block. new blocks cannot be submitted to the network without the correct answer – the process of “mining” is essentially the process of competing to be the next to find the answer that “solves” the current block. the mathematical problem in each block is extremely difficult to solve, but once a valid solution is found, it is very easy for the rest of the network to confirm that the solution is correct. there are multiple valid solutions for any given block – only one of the solutions needs to be found for the block to be solved. because there is a reward of brand new bitcoins for solving each block, every block also contains a record of which bitcoin addresses or scripts are entitled to receive the reward. this record is known as a generation transaction, or a coinbase transaction, and is always the first transaction appearing in every block. the number of bitcoins generated per block starts at 50 and is halved every 210,000 blocks (about four years). bitcoin transactions are broadcast to the network by the sender, and all peers trying to solve blocks collect the transaction records and add them to the block they are working to solve. miners get incentive to include transactions in their blocks because of attached transaction fees. the difficulty of the mathematical problem is automatically adjusted by the network, such that it targets a goal of solving an average of 6 blocks per hour. every 2016 blocks (solved in about two weeks), all bitcoin clients compare the actual number created with this goal and modify the target by the percentage that it varied. the network comes to a consensus and automatically increases (or decreases) the difficulty of generating blocks. because each block contains a reference to the prior block, the collection of all blocks in existence can be said to form a chain. however, it’s possible for the chain to have temporary splits – for example, if two miners arrive at two different valid solutions for the same block at the same time, unbeknownst to one another. the peer-to-peer network is designed to resolve these splits within a short period of time, so that only one branch of the chain survives. the client accepts the ‘longest’ chain of blocks as valid. the ‘length’ of the entire block chain refers to the chain with the most combined difficulty, not the one with the most blocks. this prevents someone from forking the chain and creating a large number of low-difficulty blocks, and having it accepted by the network as ‘longest’

Photographic, английский
Underexposure, английский
- A picture that appears too dark because insufficient light was delivered to the imaging system. opposite of overexposure.
- The result of recording too little light when taking a picture, which results in a dark image. in digital imaging, underexposure can be corrected to a certain extent by the use of image-editing software, depending upon how underexposed your image is. raw files offer more latitude than jpegs and tiffs for correcting underexposure.
- Failure to expose correctly because not enough light has struck the film or sensor to faithfully render the color and brightness values. underexposed pictures are dark; the more the underexposure the darker they become. color also suffers when film is underexposed, although a slight amount of underexposure can be used to increase color saturation in certain color slide films.
Resolution, английский
- The smallest change in the parameter being measured that causes a detectable change in the output of the instrument.
- Разрешение
- Defines the smallest resolvable object in the target plane at a given range-to-target, atmospheric condition and target signal level ability of a telescope to differentiate between two objects in the sky which are separated by a small angular distance
- The measure of the fine detail that can be seen in an image. for analog systems this is typically measured in television lines or tvl. the higher the tvl rating, the higher the resolution.
- Refers to the degree of detail of an image. it is usually measured in dots per inch (dpi) or lines per inch (lpi). a high resolution gives a high quality image and vice versa.
- The quality of any digital image, whether printed or displayed on a screen, depends in part on its resolution—the number of pixels used to create the image. more and smaller pixels adds detail and sharpens edges. l optical is an absolute number that the camera`s image sensor can physically record. l interpolated adds pixels to the image using complex software algorithms to determine what color they should be. it is important to note that interpolation doesn`t add any new information to the image it just makes it bigger! camera makers often specify the resolution as: qvga (320 x 240), vga (640 x 480), svga (800 x 600), xga (1024 x 768) or uxga (1600 x 1200)
- A measure of picture resolving capabilities of a television system determined primarily by bandwidth, scan rates and aspect ratio. relates to fineness of details perceived.
- The ability to distinguish fine detail or resolve information within an image.
- Refers to the number of pixels, both horizontally and vertically, used to either capture or display an image. the higher the resolution, the finer the image detail will be.
- The quality of any digital image, whether printed or displayed on a screen, depends on its resolution, or the number of pixels used to create the image. more, smaller pixels add detail and sharpen the edges.
- 1. the amount of detail which can be seen in a microscope or on a computer monitor 2. a point in the development of a disease where the inflammation begins to disappear
- Наименьшее расстояние между деталями, обеспечивающее их захват роботом
- Разложение (на составляющие) ~ of forces разложение сил ~ of vector разложение вектора
- Resolution is a rule used in logical inference. it states that if there is an axiom of the form (a or b) and another of the form (not(b) or c), then (a or c) logically follows. see also: modus ponens, modus tollens.
- Разрешающая способность. способность значимо различать близкие значения [28].
- A measure of the fineness of detail in an image or text, usually as produced by a monitor or printer.
- Loosely speaking, the quality of an image. when printing or working with images, the resolution is usually measured in dots per inch (dpi) - the more dots per inch, the higher the quality of the image but the larger the file needed to store it. in windows, the screen resolution is how many- pixels- fit on the desktop, the most popular being 800 x 600 and 1024 x 768 - the former makes images, icons etc look bigger, but the latter means you can fit more of them on the screen.
- The process of translation between a domain name address and an ip address.
- A document that records a decision or action by a board of directors, or a bond resolution by a government entity authorizing a bond issue.
- The number of dots in an image’s screen display or printed output. a monitor’s resolution refers to the number of pixels per linear inch. printed resolution refers to dots per linear inch. (see dpi.)
- The ability to distinguish between two points in an image
- Разрешающая способность. мера способности видеокамеры или телевизионной системы воспроизводить детали. число элементов изображения, которые могут быть воспроизведены с хорошей четкостью.
- Aspect of image quality pertaining to a system’s ability to reproduce objects, often measured by resolving a pair of adjacent objects or parallel lines. see also line pair; resolving power.
- Aspect of image quality pertaining to a system’s ability to depict objects, often measured by distinguishing (resolving) a pair of adjacent objects or parallel lines.
- A system’s ability to depict two objects or signals in close proximity as separate from one another. resolution, or resolving power, varies with size, distance, sensor characteristics, object shape, object color, and contrast. see also line pair; vision acuity.
- An aspect of image quality pertaining to a system’s ability to reproduce objects, often measured by resolving a pair of adjacent objects or parallel lines.6
