An image processing apparatus comprises a receiver (201) for receiving an image signal which comprises at least an encoded image and a target display reference. The target display reference is indicative of a dynamic range of a target display for which the encoded image is encoded. A dynamic range processor (203) generates an output image by applying a dynamic range transform to the encoded image in response to the target display reference. An output (205) then outputs an output image signal comprising the output image, e.g. to a suitable display. The dynamic range transform may furthermore be performed in response to a display dynamic range indication received from a display. The invention may be used to generate an improved High Dynamic Range (HDR) image from e.g. a Low Dynamic Range (LDR) image, or vice versa.

A method and system of identity masking to obscure identities corresponding to face regions in an image is disclosed. A face detector is applied to detect a set of possible face regions in the image. Then an identity masker is used to process the detected face regions by identity masking techniques in order to obscure identities corresponding to the regions. For example, a detected face region can be blurred as if it is in motion by a motion blur algorithm, such that the blurred region can not be recognized as the original identity. Or the detected face region can be replaced by a substitute facial image by a face replacement algorithm to obscure the corresponding identity.

An assortment of color elements is grouped within a plurality of color families which are organized in accordance with a circular color chart (FIG. 10-A) and a columnar chart (FIG. 11-A). Except for the neutral-gray color family, a pair of boundary-hues respectively defines the extent of acceptable hue variation within each group, resulting in an included range of hue within each color family, and an excluded range of hue in between neighboring color families. Variant-hue charts enhance color comparison and selection within each main color family by displaying contrasting variations of all three color attributes, that is, value, saturation, and hue, within a single chart. Variant-hue charts also consolidate color elements into a compact format, and provide a graphical user interface for computer color selection.

Scenes from motion pictures to be colorized are broken up into separate elements, composed of backgrounds / sets or motion / onscreen-action. These background and motion elements are combined into single frame representations of multiple frames as tiled frame sets or as a single frame composite of all elements (i.e., both motion and background) that then becomes a visual reference database that includes data for all frame offsets which are later used for the computer controlled application of masks within a sequence of frames. Each pixel address within the visual reference database corresponds to a mask / lookup table address within the digital frame and X, Y, Z location of subsequent frames that were used to create the visual reference database. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods. The gray scale determines the mask and corresponding color lookup from frame to frame as applied in a keying fashion.
