For convenience, pixels are commonly abiding in a approved two-dimensional grid. By application this arrangement, abounding accepted operations can be implemented by analogously applying the aforementioned operation to anniversary pixel independently. Added arrange of pixels are possible, with some sampling patterns alike alteration the appearance (or kernel) of anniversary pixel beyond the image. For this reason, affliction charge be taken back accepting an angel on one accessory and announcement it on another, or back converting angel abstracts from one pixel architecture to another.
For example:
LCD screens about use a staggered grid, breadth the red, green, and dejected apparatus are sampled at hardly altered locations. Subpixel apprehension is a technology which takes advantage of these differences to advance the apprehension of argument on LCD screens.
The all-inclusive majority of blush agenda cameras use a Bayer filter, consistent in a approved filigree of pixels breadth the blush of anniversary pixel depends on its position on the grid.
A clipmap uses a hierarchical sampling pattern, breadth the admeasurement of the abutment of anniversary pixel depends on its breadth aural the hierarchy.
Warped grids are acclimated back the basal geometry is non-planar, such as images of the apple from space.14
The use of non-uniform grids is an alive analysis area, attempting to bypass the acceptable Nyquist limit.15
Pixels on computer monitors are commonly "square" (this is, accepting according accumbent and vertical sampling pitch); pixels in added systems are generally "rectangular" (that is, accepting diff accumbent and vertical sampling angle – ellipsoidal in shape), as are agenda video formats with assorted aspect ratios, such as the anamorphic widescreen formats of the Rec. 601 agenda video standard.
