    Abstract: Techniques are described to combine image data from multiple images with different exposures into a relatively high dynamic range image. A first image of a scene may be generated with a first operational mode of an image processing system. A second image of the scene may be generated with a second different operational mode of the image processing system. The first image may be of a first spatial resolution, while the second image may be of a second spatial resolution. For example, the first spatial resolution may be higher than the second spatial resolution. The first image and the second image may be combined into an output image of the scene. The output image may be of a higher dynamic range than either of the first image and the second image and may be of a spatial resolution higher than the second spatial resolution.

    Abstract: A data structure defining a high dynamic range image comprises a tone map having a reduced dynamic range and HDR information. The high dynamic range image can be reconstructed from the tone map and the HDR information. The data structure can be backwards compatible with legacy hardware or software viewers. The data structure may comprise a JFIF file having the tone map encoded as a JPEG image with the HDR information in an application extension or comment field of the JFIF file, or a MPEG file having the tone map encoded as a MPEG image with the HDR information in a video or audio channel of the MPEG file. Apparatus and methods for encoding or decoding the data structure may apply pre- or post correction to compensate for lossy encoding of the high dynamic range information.

    Abstract: Methods and apparatus according to various aspects take as input image data in a lower-dynamic-range (LDR) format and produce as output enhanced image data having a dynamic range greater than that of the input image data (i.e. higher-dynamic range (HDR) image data). In some embodiments, the methods are applied to video data and are performed in real-time (i.e. processing of video frames to enhance the dynamic range of the video frames is completed at least on average at the frame rate of the video signal).
