Abstract: The present invention relates to a method of displaying a colour video image in a sequential colour display panel. The video frame is divided into a plurality of consecutive time segments each assigned to a given colour component, and the video level of the pixels of the image is displayed by modulating the display time of the corresponding cells. The invention aims to propose a display method that reduces the blurring effect without causing colour break-up. According to the invention, at least one reference time segment is defined in said plurality of time segments, and the image is displayed giving priority to lighting the cells during the reference time segment and the time segments closest to the reference time segment.
Application to LCOS, OLED and DMD sequential colour display panels.

Abstract: The method comprises the generation of a deteriorated image associated with a first bit rate (R1) and of a deteriorated color transform associated with a second bit rate (R2), an evaluation of a first distortion (dE1) by comparison of the image with a first test image obtained by the application of the color transform to the deteriorated image, and of a second distortion (dE2) by comparison of the image with a second test image obtained by the application of the deteriorated color transform to the image, and the determination of a final conjoint bit rate (R f ) associated with a best trade-off between a conjoint bit rate (R = R1 + R2) and a global distortion (dE = dE1+DE2).
The optimized deteriorated image and the optimized deteriorated color transform are then embedded based on this conjoint bit rate (R f ).

Abstract: Method of mapping source colors of a source color device into target colors of a target color device, comprising :
- a pre-mapping step to get a distribution of pre-mapped colors that is closer to a constant color distribution than a source distribution f S (u) of source colors of interest, and/or
- a post-mapping step to get a distribution of the post-mapped colors that is closer to a target distribution f T (u) of target colors of interest than a constant color distribution.
Importance, quality and/or occurrence of colors can then be taken into consideration for the mapping, on the source side as on the target side.

Abstract: The present invention relates to a method and a device for displaying a sequence of images that makes it possible to prevent any unauthorized copying of the latter. It applies to any type of digital display device comprising a matrix of light cells comprising a number of rows and/or columns of cells greater than the number of rows and/or of columns of pixels of the images to be displayed. According to the invention, to disrupt the illegal copying of sequences of images in cinema auditoria, it is proposed to modify the frame frequency of the displayed images by varying the number of rows and/or columns of cells addressed with a black level for at least two images of the sequence.
