HIGH DYNAMIC RANGE, BACKWARDS-COMPATIBLE, DIGITAL CINEMA
First Claim
1. A method, comprising:
- receiving a high dynamic range (HDR) image;
processing the received HDR image, wherein (a) a coded baseline image that complies with the Digital Cinema Systems Specification of the Digital Cinema Initiative (DCI Systems Standard), and (b) one or more HDR-enhancement images are created from the received HDR image;
wherein the coded baseline image comprises one or more color components, wherein the coded baseline image and the one or more HDR-enhancement images each provide enhancement information to allow reconstruction of an instance of the received HDR image using the baseline image and the HDR-enhancement images;
computing a data packet, wherein the data packet comprises;
a first data set that relates to the one or more baseline image color components, each of which has an application marker that relates to the HDR-enhancement images; and
a second data set that relates to one of the HDR-enhancement images, wherein the HDR image is coded; and
sending the computed data packet in a bit stream that conforms to the DCI Systems Standard, wherein the HDR image is distributed.

Abstract
HDR images are coded and distributed. An initial HDR image is received. Processing the received HDR image creates a JPEG-2000 DCI-compliant coded baseline image and an HDR-enhancement image. The coded baseline image has one or more color components, each of which provide enhancement information that allows reconstruction of an instance of the initial HDR image using the baseline image and the HDR-enhancement images. A data packet is computed, which has a first and a second data set. The first data set relates to the baseline image color components, each of which has an application marker that relates to the HDR-enhancement images. The second data set relates to the HDR-enhancement image. The data packets are sent in a DCI-compliant bit stream.

11. A method of decoding HDR images comprising:
-
receiving a plurality of data packets, wherein each packet comprises a first data set that relates to one or more color components of a baseline image that complies with Digital Cinema Systems Specification of DCI, each of which has an application marker that relates to an HDR enhancement image, and a second data set that relates to one of the HDR-enhancement images; decoding the first set of data wherein the baseline image is reconstructed; decoding the second set of data wherein the HDR-enhancement images are reconstructed; and combining the baseline image and the HDR-enhancement images wherein an HDR output image is generated. - View Dependent Claims (13, 15)
