This disclosure describes techniques to capture images or videos of high resolution with cameras and optical components of ordinary size and specification as found in typical webcams or smartphones. Per the techniques, one or more cameras perform an optical zoom to sections of the field of view, capturing high-resolution sub-images of the field of view. The cameras raster across the field of view, rotating as necessary, to capture high-resolution sub-images that are integrated to reconstruct a high-resolution image of the entire field of view. As the scene changes, the cameras refocus and re-capture the sections of the field of view that have experienced change, such that the image as a whole remains updated.
