Subpixel rendering is a method used to increase the effective resolution of a color display device. It takes advantage of each pixel 's composition of individually addressable red, green, and blue components adjacent on the display matrix, called subpixels , and uses them as rendering units instead of pixels.
It is also important when attempting sub-pixel resolution to keep image noise to a minimum. This, in the case of a stationary scene, can be measured from a time series of images. Appropriate pixel averaging, through both time (for stationary images) and space (for uniform regions of the image) is often used to prepare the image for sub-pixel ...
Magnified image of the AMOLED screen on the Google Nexus One smartphone using the RGBG system of the PenTile matrix family. PenTile RGBG layout used in AMOLED and plasma [8] displays uses green pixels interleaved with alternating red and blue pixels. The human eye is most sensitive to green, especially for high resolution luminance information ...
U.S. patent 6,225,973 – Mapping samples of foreground/background color image data to pixel sub-components; U.S. patent 6,243,070 – Method and apparatus for detecting and reducing color artifacts in images; U.S. patent 6,393,145 – Methods apparatus and data structures for enhancing the resolution of images to be rendered on patterned ...
Morphological antialiasing (MLAA) is a technique for minimizing the distortion artifacts known as aliasing when representing a high-resolution image at a lower resolution. Contrary to multisample anti-aliasing (MSAA), which does not work for deferred rendering , MLAA is a post-process filtering which detects borders in the resulting image and ...
The first image is on the right, and was drawn explicitly to demonstrate LCD subpixel positioning, and it compares normal greyscale antialiasing with raw subpixel antialiasing (the ugly kind :-) ) and a sort of "filtered" subpixel antialiasing, along with some color scales to let the user see the way the filter works, how the subpixels are ...
The components of the pixels (primary colors red, green and blue) in an image sensor or display can be ordered in different patterns, called pixel geometry. The geometric arrangement of the primary colors within a pixel varies depending on usage (see figure 1).
Digital image correlation and tracking is an optical method that employs tracking and image registration techniques for accurate 2D and 3D measurements of changes in images. This method is often used to measure full-field displacement and strains , and it is widely applied in many areas of science and engineering.
