Abstract: In a class of embodiments, a method and circuit for de-mosaicing and downscaling image data (e.g., image data in raw Bayer image format) in a single, integrated operation, rather than two separate and sequential de-mosaicing and downscaling operations. Some embodiments of the method include a step of displaying the de-mosaiced and downscaled data (e.g., on an LCD of a digital camera to perform an image preview operation). In typical embodiments, the method includes the steps of: determining sampling points (one sampling point for each output image pixel); and filtering the input image data to generate color component values of output image data (e.g., red, green, and blue color components of output image data in RGB format) at each sampling point without producing unacceptable aliasing artifacts.
