Summary of image processing apparatus, server data supply default mapping algorithm, method of obtaining a first image (HDR _ PRED) lumas for a first luminance dynamic range from the second image (LDR _ cont) to a second lumas Lcance dynamic luminance and method of providing data mapping algorithm of default (GAM.GAM _ ENC) transform to a second image (LDR _ cont) calibrated for rendering a display of a second dynamic range of luminance to improve security for the sale of movies of HDR (or at least experience of HDR) even when some of the data of the film are Pirat Eados, apparatus for processing image (201) is willing to produce, for example,An image of high dynamic range (HDR _ PRED) from an image of low dynamic range (LDR _ cont) or any image of dynamic range (for example, an image display drive) from any input image of dynamic range.In the achievement includes the mapping of lumas tone of pixels in the image, low dynamic range image pixels in lumas of high dynamic range by application of at least one of the default mapping algorithm (GAM),The image processing apparatus comprising: an input (204) in a distribution system data (205) comprising the image of low dynamic range; an entrance protected by data (206) in at least one of the default mapping algorithm (GAM); and a unit. Control (202) prepared to manage the access to the data of the default mapping algorithm under the COntrol of the owner of artistic content in the image of low dynamic range, which allows for better control of the regularity authorized content when it is to be rendered, which is possible due to the encoding strategy of the HDR image. 1 / 1
