Abstract
Official abstract text for this publication.
This disclosure describes techniques for rotating an encoded image, such as an image encoded according to a JPEG standard. In one example, a method for rotating an encoded image comprising reordering minimum coded units (MCUs) of the encoded image according to a specified rotation of the encoded image, rotating image data within the MCUs according to the specified rotation, and generating a rotated version of the encoded image comprising the reordered MCUs and the rotated image data within the MCUs.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method in an image capture device for rotating an encoded image comprising: reordering minimum coded units (MCUs) of the encoded image according to a specified rotation of the encoded image, wherein the MCUs are separately decodable units that are decoded without reference to another MCU; applying file size control parameters to image data within the MCUs by reducing or eliminating high frequency components within the MCUs; rotating the image dat…
