There is described a method for generating an image view from at least one input image for a 3D display using a backward processing enabling post processing for handling holes in the image view.

Method and device for generating an image view for 3D display

The invention relates to a data processing system for performing a polyphase filtering. This circuit comprises functional units () able to perform polyphase filterings, and a memory device () for storing data and coefficients. The functional units receive in parallel data and coefficients coming from the memory device, calculate results from the data and coefficients and supply these results to the memory device.

Data processing circuit

The present invention relates to a communicating data system comprising devices () for routing said data that are interconnected by communication links, the data being transmitted in packets and a packet comprising a header. A transmitting part of a first routing device () comprises first storage means suitable for storing a value of at least one parameter from said header and for transmitting a coded value corresponding thereto, and first entropy coding compression means which are suitable for recoding the uncoded value, the recoded value being stored instead of the coded value after the latter is transmitted along a communication link (). A receiving part of a second routing device (), that is connected to the first routing device by the communication link, comprises second storage means suitable for storing the coded value coming from the communication link () and for transmitting the uncoded value corresponding thereto, and second entropy coding compression means which are suitable for recoding the uncoded value, the recoded value being stored instead of the coded value.

Data communication system according to a packet-switching principle

The invention relates to a processing system comprising a calculation device comprising at least one calculation unit (), a storage device and a system for switching between the storage device and the calculation device. In order to reduce the size of the switching system, the storage device comprises several banks of registers () for storing words, the switching system comprises at least one switching device () associated with each bank of registers and the calculation units exchange a word with a bank of registers by means of the associated switching device.

Data processing system

The present invention relates to a converter converting an input digital signal into an output digital signal. Said converter comprises in particular a set of shift registers able to contain samples of the input or output digital signal. It also comprises a calculation unit able to supply a shift signal () to said set of registers. Said calculation unit comprises a first storage unit () able to contain a value of a conversion ratio or of its inverse, so that the value stored is between 0 and 1. It also comprises a second storage unit () able to contain, at a cycle time i+1, i being an integer, a future signal () equal to a sum of a current signal () contained in the second unit at a cycle time i and of the content of the first storage unit. The shift signal then results from an exclusive OR function () between a most significant bit of the current signal () and a most significant bit of the future signal ().

Digital sampling frequency converter

The present invention relates to an integrated circuit and a method of processing graphic patterns comprising pixels. The circuit (CH) is integrated in a video output co-processor. The circuit comprises, on the one hand, a random access memory (RAM) intended to save the patterns and, on the other hand, extraction means (PE) intended to extract pixels as a function of an indication of the number of bits per pixel from the selected pattern and apply them to encoding means (CM). The pixels are then color-characterized by encoding means (CM) for display on a video screen. The circuit avoids the use of an external memory (SDRAM) and thus cluttering of the passband of the video bus.
