Abstract: An apparatus for providing in-situ radiation measurements within a density equivalent package is disclosed. The apparatus may include a radiation detector embedded within the density equivalent package that is configured to measure an amount of exposure of a phantom material of the density equivalent package to radiation emitted by an irradiation device. The phantom material may have density equivalence with an object or substance for which radiation exposure information is sought and the phantom material may serve as a substitute for the object or substance. A signal including the measurement of the amount of exposure of the phantom material to the radiation may be provided to a processor of the apparatus for processing. The processor may process the signal to interpret and provide additional information relating to the measurement and may provide the information to a device communicatively linked to the apparatus.

Abstract: There is provided a method of applying colour correction to a video image obtained by scanning photographic film frames, in which each frame on the film is scanned a plurality of times to produce a plurality of constituent frames each containing only part of the data required to represent the image at a relatively high resolution, the constituent frames associated with each film frame are assembled to provide a relatively high resolution video image, and the high resolution images are stored and/or displayed. In the invention, information is stored indicating the relationship between each constituent frame and its associated high resolution image, a colour correction decision is made, and colour correction is applied to one or more of the constituent frames associated with that high resolution image.

Abstract: A method of digitally processing a sequence of video frames wherein in object which appears in the frames and undergoes relative motion or transformation is selected in a first frame by an operator; the pixels relating to the object are tagged in that frame by means of information including at least one color or appearance attribute; corresponding pixels relating to the object are located automatically in subsequent frames, by means of said information including at least one color or appearance attribute and by means of information indicating the expected position or shape of the object in the subsequent frames; and the pixels relating to the object in each of the frames are procesed.

Abstract: A digital video processor which is usable as a secondary digital color processor (DCP) with standard-definition digital telecines and is also compatible with high-definition television systems, for correcting video color and other attributes such as pixel location and sharpness. The disclosed video processor has an architecture in which only the pixels and/or regions of a video picture to be modified have any processing applied to them, so that most pixels, which are unmodified, remain free from any potential corruption. It identifies pixels to be modified by means of lookup tables which can be loaded for each frame with data indicating attributes such as hue, saturation, and luminance values or ranges which are to be present in a pixel if that pixel is to be selected for modification, the pixel's attributes being applied to each lookup table as an address.
