摘要： Simulation of film grain in an image can occur by compressing a video image, then transmitting compressed video together with a message containing at least one parameter indicative of the original film grain, to a decoder, and restoring the original grainy appearance of images by having the decoder simulating film grain based on the content of the film grain message. To improve efficiency, one or more parameters of film grain information undergo scaling in accordance with a target pixel block size for pixel blocks in the image. Such scaling allows for the use of conventional circuitry for performing block-based operations in connection with the film grain simulation.

摘要： Film grain is simulated in an output image using pre-established blocks of film grain from a pool of pre-established blocks. Successive film grain blocks are selected by matching the average intensity of a block from the pool to the average intensity of a successive one of a set of M×N pixels in an incoming image. Once all of the successive pixel blocks from the image are matched to selected film grain blocks, the selected film grain blocks are “mosaiced”, that is composited into a larger image mapped to the incoming image.

摘要： The addition of comfort noise to an image serves to hide compression artifacts. To facilitate comfort noise addition, supplemental information accompanying a video image contains at least one parameter that specifies an attribute regarding comfort noise. Typically, the supplemental information includes parameters that function to turn the comfort noise on and off, as well as to indicate the level of noise to add, based on the expected level of compression artifacts.
