20100246953 | Method for detection of film mode or camera mode - The present invention relates to a method for detection of film mode or camera mode of a video sequence. This detection is carried out using histograms of video levels of frames of the video sequence. Difference histograms are calculated then compared with each other so as to generate difference parameters for each video frame of the sequence. The pattern formed by these difference parameters is then compared with predetermined patterns to deduce the mode, film or camera, of the sequence. The advantage of this method is that it requires just small memory resources for its implementation and can therefore be implanted in an FPGA circuit. | 09-30-2010 |
20110285815 | Method for processing stereoscopic images and corresponding device - The invention relates to a method for video processing of at least one image of a video sequence, said video sequence comprising a plurality of image pairs, each image pair comprising a first image and a second image said first and second images being intended to form a stereoscopic image. In order to reduce display defects, the method comprises a step of generation of at least a third image by motion compensated temporal interpolation from at least two of said second images. | 11-24-2011 |
20130033516 | METHOD OF GENERATING A FINAL COLOUR VERSION OF A SOURCE IMAGE FROM A FIRST SET OF DIFFERENT INTERMEDIATE COLOUR VERSIONS - This method comprises the following steps: | 02-07-2013 |
20130097372 | METHOD FOR DETERMINING IDENTIFIERS OF SEGMENTS FORMING AN AUDIOVISUAL DOCUMENT AND RECEIVER IMPLEMENTING THE METHOD - The invention relates to a method for determining identifiers associated with segments of a document. Each segment consists of a series of individual elements such as images or sound sequences. Each segment of the document is subdivided into a determined number of portions comprising the same number of individual elements. An individual element is extracted from the most central portion of each segment and associated with the segment as identifier. | 04-18-2013 |
20130286286 | METHOD OF PROCESSING A VIDEO CONTENT ALLOWING THE ADAPTATION TO SEVERAL TYPES OF DISPLAY DEVICES - Method wherein each image of the content is transformed using at least one pre-transformed image which is associated with a key image of this content wherein, from each key image and an associated pre-transformed image, a color transform is derived, and wherein each color transform is applied to a selection of images of this content which is associated with said key image. Applied to a content broadcast system comprising a server and a receiver to which are connected several types of display devices, the invention advantageously makes it possible to adapt the content to these different types. | 10-31-2013 |
20150050007 | PERSONALIZED MULTIGRANULARITY VIDEO SEGMENTING - The invention pertains to method for segmenting an audiovisual content in a semantic manner and in quick way. To achieve that, pre-segmentation data are generated offline and retrieved by an end user. At the level of the end user, a step of clustering segments is performed. The invention allows also to approach a desired semantic granularity by modifying a clustering threshold. The invention also allows to quickly generate a semantic segmenting for a segment, which allows to the user to quickly browse the audiovisual content. | 02-19-2015 |

20090184900 | Image display device and display device control method - The invention relates to an active matrix image display device consisting of: several light emitters; a current modulator which is connected to each emitter; means for selecting emitters; means for powering the emitters; and an operational amplifier comprising an inverting input a noninverting input and an output. According to the invention, either the noninverting input or the inverting input of the operational amplifier is connected to the output of the power supply means such as to form, together with the modulator gate which is connected to the output of the operational amplifier, a feedback loop for the operational amplifier, when one of the emitters is selected. The invention also relates to a method of controlling one such display device. | 07-23-2009 |
20090316784 | Device for generating an interpolated frame - The present invention is situated within the frame or video processing domain and more particularly in the domain of video interpolation. It relates to a device for generating an interpolated frame from source frames temporarily surrounding it. This device comprises motion estimation means, motion compensated interpolation means, linear interpolation means, means for mixing the frame produced by the motion compensated interpolation means with the frame produced by the linear interpolation means. According to the invention, the mixing coefficients assigned to these two frames depend on the displaced frame difference and/or the frame difference between the source frames surrounding this interpolated frame and/or estimated motion vectors. | 12-24-2009 |

20090150583 | Video data processing module furnished with a configurable video processing unit with a single input bus - According to the invention, the video data to be processed and the configuration data are transferred to the module via one and the same data bus. These modules are advantageously chained in series on a common bus which transfers to each module both the configuration data and the video data to be processed. Preferably, dead time or “blanking” periods between two picture frames transmitted on this bus are used in order to insert the configuration data. | 06-11-2009 |
20090161018 | Video picture display method to reduce the effects of blurring and double contours and device implementing this method - The present invention relates to a video picture display method that aims to reduce the effects of blurring and multiple contours when the picture display frequency is doubled. According to the invention, for each source video picture, a video level dissymmetry is created between the two pictures from the source video picture after doubling the frequency in the areas in motion of the source video picture. | 06-25-2009 |
20090167936 | Video picture format conversion method and corresponding device - The present invention can be implemented in a video coder or decoder or directly in any type of display device. According to the invention, a distance representative of the edge orientation in the input picture is calculated, for at least one point situated inside a zone delimited by a first set of neighbouring pixels of the input picture, it is calculated independently from the grid of pixels of the output picture. For at least one pixel of the output picture situated in this zone, a second set of pixels is determined in the input picture from the distance and the position of said pixel of the output picture in this zone. The value of this output pixel is then determined from the value of the pixels of said second set of pixels. This method enables a reduction in the number of calculations for this format conversion. | 07-02-2009 |
