Effective Pixel Count

Technology / Digital Cameras / Effective Pixel Count: There are two different ways to think about the pixels on a camera's image sensor. 'Actual' pixels is a simple count of every pixel present on the sensor. 'Effective' pixels, however, is a count of al MORE

Megapixel (MP)

Technology / Digital Cameras / Megapixel (MP): One million pixels. The more megapixels a camera has, the higher its maximum resolution — and the better its potential picture quality. MORE

Pixel Size

Science / Spiders / 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 fact MORE
