20090184978 | Image Processing Method for Increasing the Blurring of Pirated Images - The image is broken down into a breakdown color space. For each broken down source pixel, if a source point P | 07-23-2009 |
20100026613 | Methods for Sequential Color Display by Modulation of Pulses - Each color image is decomposed into at least one series of at least three successive primary images of different primary colors which are successively displayed by modulating the activation duration of the pixels of an imaging device. According to the invention, the distribution of the pixel activation phases in the three successive subframes is contracted: the pixel activation periods of the first primary image are shifted toward the end of the subframe of this first image, and, during the subframe of the third primary image, the pixel activation periods of this third primary image are shifted toward the beginning of the subframe of this third image. Color break-up faults are thus advantageously reduced. | 02-04-2010 |
20100085491 | PROJECTION SYSTEM BASED ON METAMERISM - The invention relates to a projection system for displaying at least one visual image based on three primary colours, comprising a signal processing unit for converting said visual image into at least a visual image based on four primary colours, a frequency band being associated to each colour primary, first display means for displaying three first primary colours of said visual image on a screen and second display means for displaying at least the fourth primary colour of said visual image on said screen. According to the invention, the system further comprises optical filtering means that are adapted to enhance the separation between the frequency spectrum of the first three primary colours of the first display means and the frequency spectrum of the at least fourth primary colour of the second display means. Application to anti-camcorder systems. | 04-08-2010 |
20100128976 | METHOD FOR DESCRIBING AN ACTUAL COLOR GAMUT OF A COLOR DEVICE OR OF A COLOR CONTENT - To describe the actual color gamut, a hierarchical structure is proposed which comprises, from bottom to top:

20100309231 | METHOD FOR ADJUSTING THE SETTINGS OF A REPRODUCTION COLOR DEVICE - According to this method, successive iterations are launched according to the following steps:—1) the reproduction color device is set according to settings,—2) reference input colors are calibrated putting calibrated input colors,—4) reproduction quality rating value are calculated,—5) a reproduction quality criterion is applied to decide or not to go for another iteration with different settings. This method allows the optimization of the settings according to color preferences. | 12-09-2010 |
20100328341 | METHOD OF CREATING A GAMUT BOUNDARY DESCRIPTOR PRESERVING THE DISCONTINUITIES OF AN ACTUAL GAMUT SURFACE - In order to preserve the discontinuities of an actual gamut surface and/or the discontinuities of its curvature, notably through a smoothing operation, in this method, when at least a vertex of any elementary polygon, the network of which represents an actual gamut boundary, belongs either to a line or a point of discontinuity of this actual gamut boundary, either to a line or a point of discontinuity of curvature of said actual gamut boundary, or both, metadata related to this belongings are added to the definition of the elementary polygons. | 12-30-2010 |
20130027567 | APPARATUS FOR THE CLASSIFICATION OF OBSERVERS ACCORDING TO THEIR VISUAL CHARACTERISTICS - Preferably, seven classes of observers are defined, according to different sets of Colour Matching Functions. By displaying specific colour patches of a classification chart using colour display devices having different sets of primaries, and by asking an actual observer to compare his perception of the same colour as displayed on each colour display device, the method allows assigning said observer his specific class. It is proposed a specific apparatus to implement this method. | 01-31-2013 |
