Specifically, the range is the pixel response time of an LCD, or how quickly a sub-pixel's brightness changes from one level to another.

However, such high refresh rates may not be actually supported by pixel response times and the result can be visual artifacts that distort the image in unpleasant ways.

First the screen is brightened and the response time is measured as in cathode ray timing, but the computer measures only which scanline was hit and not which horizontal pixel was hit.

To remedy this, the response of each pixel is measured at the factory, and a transform, most often linear, maps the measured input signal to an output level.

The pixel response time is also fairly slow, at the range of tens of milliseconds.

However, such high refresh rates may not be actually supported by pixel response times and the result can be visual artifacts that distort the image in unpleasant ways.

Typically LCD pixel brightness changes are faster when voltage is applied than when voltage is removed, resulting in an asymmetric pixel response time.

These CRT kits were entirely incompatible with common LCD monitors which had very high pixel response times, unlike CRT displays.

In response to a question of what they would be called, he coined the term " vexel " as a combination of vector and pixel since they were not simply rasters, and those asking needed a name for a new style.

This camera is composed of four 4096x4096 pixel non-butted Fairchild CCDs that are thick and front-illuminated, thus have a response peaking in the red with approximately 42 % quantum efficiency.

One is the DSNU ( dark signal non-uniformity ), which is the offset from the average across the imaging array at a particular setting ( temperature, integration time ) but no external illumination and the PRNU ( photo response non-uniformity ), which describes the gain or ratio between optical power on a pixel versus the electrical signal output.

The latter can be described as the local, pixel dependent photo response non-linearity ( PRNL ) and is often simplified as a single value measured at almost saturation level to permit a linear approximation of the non-linear pixel response.

In practice, a long exposure ( integration time ) emphasizes the inherent differences in pixel response so they may become a visible defect, degrading the image.

In these printers, a comb of hammers printed a portion of a row of pixels at one time, such as every eighth pixel.

* Response time is the time a pixel in a monitor takes to go from active ( white ) to inactive ( black ) and back to active ( white ) again, measured in milliseconds.

Image data that uses indexed color specifies addresses within the CLUT to provide the required R, G, and B values for each specific pixel, one pixel at a time.

Response time is the amount of time a pixel in an LCD monitor takes to go from one value to another and back again.

In these printers, a comb of hammers printed a portion of a row of pixels at one time ( for example, every eighth pixel ).

The Michelson or Fourier transform spectrograph was popular for infra-red applications at a time when infra-red astronomy only had single pixel detectors.

# The retina performs all these calculations in parallel while the computer operates on each pixel one at a time.

For a variety of reasons, this can take much less time than " getting " each pixel individually, as with traditional CPU design.

Every time a pixel on a triangle is rendered, the corresponding texel ( or texture element ) in the texture must be found.

The 8b10b encoding system serves several purposes: it preserves DC balance over time, it generates sufficient signal transitions to maintain receiver bit-alignment ( pixel clock recovery ), and it provides symbol ( byte ) alignment.

Rather, a given position could be accessed only when the desired scan-line and pixel time rolled around.

Unlike most other arcade games of the time, the course images were not drawn on the pixel level.

Phong's methods have proven popular due to their generally efficient use of computation time per rendered pixel.

Phong's methods have proven popular due to their generally efficient use of computation time per rendered pixel.

The game was very similar in style and gameplay to other fighting games popular at the time, such as Street Fighter II and Mortal Kombat, but with pre-rendered CGI sprites rather than pixel art.

More specifically, ground truth may refer to a process in which a pixel on a satellite image is compared to what is there in reality ( at the present time ) in order to verify the contents of the pixel on the image.

An early pioneer of pixel art, her most recognizable works from her time with Apple are the Chicago typeface ( the most prominent user interface typeface seen in Classic Mac OS, as well as the typeface used in the first four generations of the Apple iPod interface ), the Geneva typeface, the original monospace Monaco typeface, Clarus the Dogcow, the Happy Mac ( the smiling computer that welcomed Mac users when starting their machines ), and the symbol on the Command key on Apple keyboards.

In digital images there is a subtle distinction between the Display Aspect Ratio ( the image as displayed ) and the Storage Aspect Ratio ( the ratio of pixel dimensions ); see distinctions, below.

In a 2D image element, which stores a color for each pixel, additional data is stored in the alpha channel with a value between 0 and 1.

A value of 0 means that the pixel does not have any coverage information and is transparent ; i. e. there was no color contribution from any geometry because the geometry did not overlap this pixel.

A value of 1 means that the pixel is opaque because the geometry completely overlapped the pixel.

Assuming that the pixel color is expressed using straight ( non-premultiplied ) RGBA tuples, a pixel value of ( 0. 0, 0. 5, 0. 0, 0. 5 ) implies a pixel which has 50 % of the maximum green intensity and 50 % opacity.

However, if this pixel uses premultiplied alpha, all of the RGB values ( 0, 1, 0 ) are multiplied by 0. 5 and then the alpha is appended to the end to yield ( 0, 0. 5, 0, 0. 5 ).

where is the result of the operation, is the color of the pixel in element A, is the color of the pixel in element B, and and are the alpha of the pixels in elements A and B respectively.

By using the palette to mask the top area of the display and taking care about when it changes mode it can shift the continuous graphics at the bottom of the display down in two pixel increments because the internal display counter is not incremented on blank scanlines during non-continuous graphics modes.

In ray casting the geometry which has been modeled is parsed pixel by pixel, line by line, from the point of view outward, as if casting rays out from the point of view.

Another calculation is made of the angle of incidence of light rays from the light source ( s ), and from these as well as the specified intensities of the light sources, the value of the pixel is calculated.

This is all repeated for each sample, for each pixel.

Aliasing typically manifests itself as jaggies, or jagged edges on objects where the pixel grid is visible.

Thus, on a real computer display, each pixel is actually composed of separate red, green, and blue subpixels.
