摘要： In a method of measuring noise in image signals, a number of noise estimates (SAD) is calculated (1). Subsequently, it is determined (3-9) which noise estimation interval [A, B] out of a plurality of predetermined noise estimation intervals [A, B] contains at least a predetermined number of noise estimates (SAD) and has at the same time the lowest upper interval boundary. The output noise measurement value depends on the determined noise estimation interval.

摘要： The horizontal definition of an interlaced television signal sampled in anti-phase from picture to picture can be enhanced by using a selection circuit with which a signal sample located horizontally between two successive signal samples from the current field is obtained from three horizontally successive signal samples of two successive pictures, which signal sample can be added between these signal samples from the current field.

摘要： A color image is enhanced in the following fashion. A saturation detector (SDT) detects a degree of color saturation (LC, CC) that occurs in an image area (SP). A filter arrangement (DE1, DE2, DE3) filters at least one spatial detail in the image area to a degree that depends on the degree of color saturation. This allows an improvement of perceptual quality of color images.

摘要： The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (76, 78, 80, 82) derivable from electromagnetic radiation (14) emitted or reflected by an object (11) is received and a plurality of characteristic index elements (50) varying over time can be extracted therefrom. The index elements (50) comprise physiological information (48) indicative of at least one at least partially periodic vital signal (12), and a disturbing signal component (58). For eliminating the disturbing signal component (58) to a great extent, the characteristic index elements (50) can be projected to a disturbance-reduced index element (64) having a distinct orientation in relation to a presumed orientation of the disturbing signal component (58). The disturbance-reduced index element (64) is chosen so as to reflect a dominant main orientation and length of the disturbing signal component (58) over time. Consequently, the mainly genuine physiological information (48) extracted from the data stream (76, 78, 80, 82) in this way can be utilized for determining the at least one at least partially periodic vital signal (12).

摘要： A method of forming a time-varying signal representative of at least variations in a value based on pixel values from a sequence of images, the signal corresponding in length to the sequence of images, the method includes acts of obtaining the sequence of images. A plurality of groups of sub-sets of pixel values are formed by selecting a sub-set of at least one pixel value from each of at least two images defining an interval to form a group of associated sub-sets. For any pair of groups with only sub-sets from the same images, the sub-sets from more than one image are different. Groups of sub-sets are selected to form the signal in accordance with at least one selection criterion. The selected groups of sub-sets cover different intervals, shorter than a length of the sequence.
