1. An image processor arranged to generate a secondary image by under-sampling a primary image using a kernel having m rows and n columns of kernel values, wherein the kernel has a plurality of kernel sampling positions for each row of the primary image, each kernel sampling position for a row separated by a stride distance of x pixels, wherein the image processing engine comprises a data streaming engine configured to:
form a first data stream of pixel values, wherein the first data stream is formed by reading image pixel values of the primary image row by row, each pixel value corresponding to a row position and a column position within the kernel;
form a second data stream of kernel values, each kernel value corresponding to a row position and a column position within the kernel, and
synchronise the pixel values of the first data stream with the kernel values of the second data stream so that each pixel value is paired with a respective kernel value corresponding to the same row position and column position within the kernel.
