Systems and methods for downscaling an image
Systems and methods for downscaling an image. An original image, represented by a collection of individual pixels, is provided so as to be downscaled. One or more of the scan lines of the original image are selectively skipped. One or more of the pixels of non-skipped scan lines are selectively skipped. The remaining pixels are then used to provide the pixels of the downscaled image. In a further implementation, the remaining pixels are used by selectively being averaged to downscale the image. Accordingly, a reduced number of pixels are averaged in order to create a new pixel of the downscaled image. Implementation of the present invention may also avoid a division process by using a right shift instead of division in the averaging process. Accordingly, implementation of the present invention reduces the time required to downscale an image and is also device independent.
