Abstract: The invention discloses an array of pixels to be arranged in electronic color imaging devices, where the risk of aliasing is reduced by arranging the pixels in the array according to irregular patterns. The array is provided with a first, a second and a third set of pixels representing a first, a second and a third color respectively. The pixels in the first set of pixels and/or the pixels in the second set of pixels are arranged in at least a first spatial frequency, and the pixels in the third set of pixels are arranged in at least a second spatial frequency. In addition, one of said first or second set of pixels may be arranged in at least a third spatial frequency. None of said first, second and third spatial frequencies are harmonics of each other. The array may be implemented in one or several different matrixes of pixels.
