摘要： The method is characterized in that it comprises the following steps:

partitioning of the 2D image into 2D zones (2) as a function of the depths assigned to the pixels, a zone being defined by a minimum and maximum depth,
calculation of blur of a 2D zone by convolution for the pixels on either side of the boundary with another zone, the size of the convolution kernel (24, 25) being dependent on the depth of the pixels of the 2D zone processed.

Applications are the creation of special effects for video games, film production.

摘要： The invention relates to a method of processing video images which is intended to correct the distortions created by the instability of the high voltage circuit of the cathode ray tube display device during the displaying of the images. It is more particularly intended for correcting the global zoom and the local zoom affecting the images displayed by the cathode ray tube device.

摘要： A method for addressing cells in devices via an I2C bus is suggested, in which the common addressing scheme is supplemented by a 'Data Transfer Mode' byte. The 'Data Transfer Mode' byte specifies the number of the address and data bytes to follow the device addressing and thereby allows for orthogonal and scalable addressing of cells inside a device connected to the bus. The method is fully compatible to the existing I2C standard for writing to the slave device. Setting up and terminating a connection between a master and a slave as well as acknowledging receipt of a byte follows the standard.

摘要： The present invention relates to a method for enhancing the contours in a video image. It applies more particularly to cathode-ray tube digital televisions. The method of the invention consists in detecting the contours of the images, in oversampling the image signal to be provided to the tube, in increasing the video level of at least one of the samples of the pixels corresponding to a contour while preserving the luminous energy of each of the pixels, then in converting the modified signal into an analogue signal intended for the cathode-ray tube. The contours then appear finer and more visible on the screen of the television. Preferably, the modification of the sampled signal consists in reducing the number of samples of the pixel corresponding to a contour and in redistributing the video level of the samples removed to the other samples of the pixel of the contour.
