Techniques to facilitate use of small line buffers for processing of small or large images

摘要

The disclosure describes image processing techniques useful for devices that support image processing of different sized images. The techniques can be used in many contexts, and may be particularly useful for front-end image processing of small viewfinder images and large still images captured by the device. In one embodiment, this disclosure provides a method comprising capturing a first image with a device, processing the first image using line buffers sized to accommodate an image width of the first image, and capturing a second image with the device, wherein the second image has an image width larger than the image width first image. The method also includes processing the vertical stripes of the second image using the line buffers, wherein the vertical stripes of the second image define widths that fit into the line buffers.
