Demosaicing Algorithms: Color Filtering
A more economical and practical way to record the primary colors is to permanently place a filter called a color filter array over each individual photosite.

Algorithm
A set of processing or working instructions that, because of their high precision, can be carried out independently by a mechanical or electronic device. Algorithms are, for example, the set rules for addition and subtraction etc.

NR algorithms don't touch sharp edges, which have high amplitude detail. NR smudges low-amplitude details and flat areas.
Even more devious and helpful than the 100% amplitude target I have, would be a star target with targets of varying contrasts.

The algorithm Print Friendly uses cleans and optimizes webpages for print by removing the ads, navigation, and any other junk you wouldn't want to see in your print out.

These algorithms adapt their method of estimation (i.e. the estimation formula) depending on features of the area surrounding the pixel of interest.

The unique algorithms developed by our team solve super-resolution problems within the tight resource requirements of mobile devices where CPU and memory resources are severely limited.

While these algorithms are extremely advanced, they lack a certain something called the human touch.

Algorithm In CCD imaging, an algorithm usually refers to a software procedure, often for image processing. An algorithm is the mathematical function which tells the computer what to do with an image.

An improved algorithm was developed, and a high degree and a high-resolution were achieved. - JPEG/TIFF development Mode, Now it is possible to convert JPEG and TIFF which is similar to a RAW data.

Artifacts are distortions of an image either produced by the CCD, the optical system or compression algorithms such as JPEG.

Photoshop CS and above add two new resampling algorithms: Bicubic Smoother and Bicubic Sharper. These alter the calculations used for standard Bicubic to optimize it for a desired effect.

Evaluative metering - also called Matrix Metering - depends on complex algorithmic calculations performed by your camera's computer chip.

There is a gnawing fear that somehow because JPEG is a "lossy" compression algorithm you'll be throwing away that vital pixel.

Many algorithms involve looking at the pixel's nearest neighbors and coming up with some sort of an average; other algorithms are more sophisticated and take several different factors into account.

Working separately on the same problem, both Cox and Knoll arrived at very similar solutions-an interpolation algorithm that's optimal for smaller images without a lot of very high-frequency film grain-essentially, digital captures.

Improved flash metering algorithms.
First, E-TTL II examines all evaluative metering zones both before and after the E-TTL preflash goes off. Those areas with relatively small changes in brightness are then weighted for flash metering.

Digital cameras have some really great white balance algorithms that can work wonders when dealing with various light sources.

The power of SilkyPix lies in the high quality interpolation algorithm of the RAW data and user-selectable precision control (Demosaic Sharpness slider). A 100% setting will force extraction of the full resolution of data that seems possible.

Of course, better in-camera noise reduction algorithms in the newer digital cameras can counter this tendency toward more noise to a certain extent.

I am not an expert in this, but I believe that the software applies a nonlinear mapping algorithm to bring all this brightness into the visible range. I has to be nonlinear vs. just compressing in order to preserve relative and absolute contrast.

Experiment with algorithms and their parameters on a reduced-size version of your image (you can pick a smaller one from the dropdown box of different sizes near the top left).

Lattice density Lattice density parameter controls the density of the elastic distortion lattice in the alignment algorithm.

The process of encoding files through an algorithm, which decreases the size for storage or transmission over the Internet. There are two types of compression: lossy and lossless.

LZW - Abbreviation for Lempel-Ziv Welch compression, the algorithm designed by Terry Welch in 1984 for use in high-performance disk controller hardware and used by the Unix compress command to reduce the size of files for archiving or ...

JPEG is an algorithm designed to work with continuous tone photographic images) which takes image data and compresses it in a lossy manner (this means you do lose some information).

The CP 800 has the same CCD and algorithm as the bigger brother CP950 and almost indentical features as S10 (surprise, surprise) making images with excellent exposure.

Exposure Metering Patterns: Many SLRs today have very sophisticated metering systems that analyze a scene and make calculations based on algorithms that have been pre-programmed into the camera.

GIFs store bitmaps in patterns of indexed 8-bit color (256 colors or less) using a special algorithm called Lempel-Ziv-Welch (LZW). Using this algorithm, gifs compress the raw bitmaps into smaller file sizes.

Amount acts a bit like Amount in Unsharp Mask, although the scale is different (the algorithms are different, too). Radius is similar to Radius in Unsharp Mask, but it's more sensitive. Detail changes how much the halos created by Radius appear.

Remember, sharpening algorithms and filters work by darkening dark areas and brightening bright areas. If you think about it, that's literally what it means to add contrast to something.

This is the name of the committee that designed the standard image compression algorithm. JPEG was designed for compressing full colour or grey scale digital images of natural scenes.

Digital Compression of Image Files Digital compression uses complicated algorithms and mathematical formulas to compress digital images. In fact, digital cameras digitally compress files as a standard part of data storage in order to consume ...

In Nikon D-SLRs, moiré is greatly reduced by means of advanced image processing algorithms and optical low-pass filters. Monaural Sound reproduction that uses only one channel.

Compression
Compression is the process of compacting digital images using software algorithms to subtract data. Smaller image files are easier to store and manage.

Even in cameras that do not allow the photographer to manually select the metering style, some cameras are beginning to use a smart metering algorithm that allows the camera to meter off of the obvious subjects in a frame rather than purely off of ...

sharpening filters
a series of digital processes or algorithms that enhance the sharpness of an image.

That 14-bit RAW gets trimmed in Adobe Bridge, but then is hacked to pieces once the JPEG algorithms compress it to 8-bits.

If you convert RAWs via other imaging applications the LW/PH figures will be lower or higher due to the different sharpening & contrast algorithms.

I knew the sun wouldn’t be a major factor in that matrix metering algorithms are programmed to ignore specular points of light. Just to be safe, I set the camera to a three stop bracket of 1 stop under / on / 1 stop over.

Some of the photography software products let you auto-correct a photo - improving the quality of your photo by using a sophisticated computer algorithm. You can also add an artistic touch through the use of textures.

However, if you need to crop an image to centre on a small area, you can find yourself with a much smaller image that will become pixelated if you print it large. Genuine Fractals has a scaling algorithm that detects hard edges and preserves them in ...

And because photographers often push the limits of safe no-decompression diving, the computer should have a conservative algorithm. Then, just to be extra careful, I like to wear a redundant computer as well.

process that "shrinks" images so they occupy less storage space, and can be transmitted faster and easier. Generally accomplished by removing the bits that define blank spaces and other redundant data, and replacing them with a smaller algorithm that ...

The cameras use white as a reference and adjust the colour balance to give as true as possible a white, correcting all the other colours by doing this. HP colour scientists have developed a family of algorithms to automatically adjust white balance ...
