Pixel Size: the number of Angstroms per pixel in the digitized micrograph. Pixel size is computed as ps (A/p) = [10,000(A/u) * SR(u) * DF] / M, where ps = pixelsize, SR = scanning resolution, DF = decimation factor, M = magnification, (units: A = Angstroms, p = pixels, u = microns). Thus, if the images were acquired at 50,000 magnification, scanned at 7 microns, then reduced in size by 2, the pixel size would be (10000 * 7 * 2)/50000 or 2.8 Angstroms/pixel.

Pixels (Phosphors): Phosphorescent dots, arranged in horizontal lines on the television screen, which produce the video image when struck by a beam from the electron gun.

Pixels: Abbreviation for picture elements. The tiny squares of light making up the picture are transmitted in digital form and reconstituted as a visual image.

Pixelization: Pixelization occurs due to errors in decoding the MPEG bit stream where areas or patches of color appear instead of the higher resolution image. It might be described as the picture 'breaki . . . View Full Definition
