    摘要: A method for deterministic film grain addition, e.g. to video signals compressed in a way that the grain is lacking. The method of electronic image processing comprises: determining a first random value (R1) corresponding to a first horizontal pixel position (h1) in a vertically positioned first horizontal line (L1) of an inputted picture (PIC); and—deriving a resultant value (R) for a second horizontal pixel position (h2) in a vertically positioned second horizontal line (L2), the resultant value depending on the first random value and a second random value (R2) corresponding to the second horizontal pixel position in the second horizontal line, random values for horizontally neighboring pixel positions being determined by successive outputs of a single random generator initialized with a seed, wherein the first random value is determined with a first random generator (n1) initialized with a first seed (S1) for a firstmost horizontal pixel position in the first horizontal line (f1), and the second random value is determined with a second random generator (n2) running in parallel with the first random generator, and initialized with a second seed (S2) for a firstmost horizontal pixel position in the second horizontal line (f2), which second seed (S2) is substantially equal to a random value obtained by applying the first random generator (n1) for the firstmost horizontal pixel position in the second horizontal line (f2) after having consecutively been applied to all horizontal positions on a left-right-top-bottom zig-zag scan path (ZZ) being initialized with the first seed (S1) and starting from the firstmost horizontal pixel position in the first horizontal line (f1). The advantage is lower memory requirements for deterministic film grain addition.

    摘要: A system (100) and a method for controlling an environmental physical characteristic in an environment of a person (105), a color and intensity tunable lamp, an electronic device and a computer program product are provided. The system (100) comprises an environment influencing means (102), a sensor (104), an input means (134) and a controller (130). The environment influencing means (102) changes the environmental physical characteristic in response to a control signal (112) indicating a desired influencing of the environmental physical characteristic. The sensor (104) obtains a sensor signal (122) representing a physiological condition of the person (105). The input means (134) obtains a user setting signal (132) representing a user setting with respect to the environmental physical characteristic. The controller (130) receives the sensor signal (122) and the user setting signal (132) and generates the control signal (112) by applying an original function (114) to the sensor signal (122). The controller (130) defines an adapted function in response to receiving the user setting signal (132), wherein the adapted function provides the control signal(112) which, if applied to the sensor signal (122) occurring when the user setting signal(132) was received, causes the environmental physical characteristic to become closer to the user setting than when the original function (114) is applied to the sensor signal occurring when the user setting signal (132) was received. The controller (130) subsequently applies the adapted function. Finally, the controller (130) gradually changes the applied adapted function towards another function.

    摘要: An image signal is encoded to reduce artifacts. In an original image frame (F) one or more gradual transition areas (R) are identified, in a decoded frame (F) corresponding one or more gradual transition areas (R) are identified, functional parameters describing the data content of the one or more gradual transition areas of the original image frame are established and position data (P) for the positions of the one or more corresponding areas (R′) in the decoded frame (F′) are established. Replacing the content of the areas R′ in the decoded frame with the reconstructed content of the areas R in the original frame improves the quality of the decoded frame.

    摘要: A set of images (IM 1 a, IM2a, IMFa) that have successively been captured comprises a plurality of images (IM 1 a, IM2a) that have been captured under substantially similar light conditions, and an image (IMFa) that has been captured under substantially different light conditions (FLSH). For example, two images may be captured with ambient light and one with flashlight. A motion indication (MV) is derived (ST6) from at least two images (IM 1a, IM2a) that have been captured under substantially similar light conditions. The image (IMFa) that has been captured under substantially different light conditions is processed (ST7, ST8) on the basis of the motion indication (MV) derived from the at least two images (IM1 a, IM2a) that have been captured under substantially similar light conditions.
