The purpose of the invention is a method for activating a mobile device in a network comprising at least one display device being coupled to a sensor. This method is characterised by the fact that it comprises: detecting the mobile device via the sensor coupled to the display device; displaying a device representative of the detected mobile device, called a virtual device, on the display device such that the position of the virtual device on the display screen is linked to the position of the mobile device in the capture field of the sensor; activating the mobile device in the network when a determined action is applied by the user to the mobile device. Another purpose of the invention is a display device and a system implementing the method.

The present invention generally relates to COLOR transfer between two images. COLOR transfer is a known technic consisting in modifying the COLORs of a source image by applying the COLOR palette of an example image without changing the source image structure. A lot of COLOR transfer method are known which consist in transferring COLORs between two images, however, those methods do not preserve the quality of the bokeh in areas of an images that are not in focus at a given depth. This results in a navigation in the depth dimension that is not smooth. It is proposed to modify the COLORs of a focal stack of a scene according to a COLOR palette by propagating the COLORs of the pixels in focus in different layers of the reCOLORed focal stack to the layers of the reCOLORed focal stack located behind the layer wherein a considered pixel is in focus.

In accordance with an exemplary embodiment, a method is provided to generate a color look up table for multiple images. The method includes selecting color points from a first image. The first color points comprise weak image texture. The method also includes identifying feature points in a spatial neighborhood of each first color point. Additionally, the method includes identifying feature points from a second image. The second feature points correspond to the first feature points. The method also includes determining a color points in the second image. The second color points correspond to the first color points, and are determined using a spatial interpolation of the first plurality of color points from the first plurality of feature points and then applying the obtained spatial interpolation to the second plurality of feature points. Further, the method includes generating the color lookup table.

An Orthogonal Frequency Division Multiplexing (OFDM) receiver that employs N second-order phase-lock loops sharing a common integrator (where N is the number of pilots in the system). The N second order phase-lock loops track out independent pilot phase rotations to facilitate the constructive averaging of the pilots' phase information. At the same time, by sharing a common integrator, the OFDM receiver takes advantage of noise averaging over multiple pilots to obtain a cleaner frequency offset estimation. The OFDM receiver may also compensate for FFT window drift by calculating a phase difference between a selected pair of pilots and tracking the rate of change of the calculated phase difference over time. The calculated phase difference is used to control the position of an upstream FFT window after a predetermined phase difference threshold is exceeded. The tracked rate of change is used to continuously adjust the phase of downstream equalizer taps.

A technique for controlling a transmitter apparatus is useful for reducing power consumption, and may be particularly applicable to portable apparatuses such as mobile transceivers which employ a battery power supply. According to an exemplary embodiment, the transmitter apparatus includes a power amplifier for amplifying a transmission signal. A processor controls the power amplifier based on a type of digital modulation associated with the transmission signal.

The gain control method for the RF and IF amplification stages of a bursty data frame reception system enables, following a step for evaluating the received signal strength, the gain adjustment step of the RF amplification stage to be temporarily deferred until a frame structure symbol is received, during which the gain adjustment step of the IF amplification stage takes place simultaneously with that of the RF gain, while retaining an overall gain linearly dependent on the input signal strength. The corresponding device comprises a control elementwhich generates the control signal for the RF and IF gain amplifiers

The disclosed embodiments relate to exploiting circuitry that exists in a typical Orthogonal Frequency Division Multiplexing (OFDM) receiver to find the phase of a complex number corresponding to an input signal without implementing additional costly circuitry or employing a relatively slow inverse tangent look-up table. The magnitude of the complex number is normalized and processed through a closed loop to produce an output proportional to the phase of the complex number.
