A digital camera captures successive first and second images using an image sensor to produce image data, and processes the image data of the successive first and second images. The processing of the second image overlaps processing of the first image in time. The processing of the two images includes mapping locations in a virtual memory space to locations in the memory pages in a physical memory space of the digital camera, and storing information corresponding to the mapped locations in a page table. The digital camera performs operations on the image data of the first and second images stored at specified locations in the virtual memory space, and while performing those operations allocates and de-allocates memory pages in the physical memory space to virtual memory pages in the virtual memory space and updates the page table accordingly.
