Abstract
Systems and methods are provided for image scaling with quality control. One embodiment is an image scaling system that includes a processor configured to receive an instruction to scale an input image by a scale factor to create an output image. The processor is configured to determine an integer quality level to use in scaling the input image to create the output image, to divide the input image into regions of consecutive pixel pairs based on the scale factor and the integer quality level, and to determine region factors corresponding to each of the regions. The processor is further configured to scale the input image by applying the region factors to pairs of pixels in the corresponding regions of the input image to create output pixels in the output image.
