摘要： In a method and device for improving image rendition by contrast and/or sharpness enhancement the sharpness enhancement is made dependent on the local average luminance value. A mix is made of spatially enhanced image signals is used, wherein for various signal differing spatial frequencies are boosted. The mixing factors for mixing of the boosted signals are dependent on a local average luminance value such that the distribution over frequency bands shifts to higher frequencies and sharper enhancement as the luminance value increases.

摘要： An encoder comprises a receiver (101) for receiving a video signal comprising at least one image. An estimator (107) determines a veiling luminance estimate for at least part of a first image of the at least one image in response to image content of one or more of the images. The veiling luminance estimate reflects an amount of eye glare generated in the eye by the image when rendered. A quantization adapter (109) determines a quantization scheme for the at least part of the first image in response to the veiling luminance estimate and an encoding unit (103, 105) encodes the video signal using the quantization scheme for the at least part of the first image. The veiling luminance estimate may be low-pass filtered to emulate human luminance adaptation. A corresponding decoder is provided. Improved encoding can be achieved, especially for High Dynamic Range images.

摘要： A method for modifying an image being defined by a matrix of pixels comprises: .calculating (1) a color frequency distribution of the matrix of pixels; . defining (3) for each pixel an energy value as a weighted function of the color frequency of the pixel, so as to define an image saliency map; .transforming (5) the image, said transformation being based on the pixel energy values. A computer software product to apply the method, an apparatus and a TV set are also disclosed.
