摘要： Described herein is a method for recognizing a human head in a source image. The method comprises detecting a contour of at least part of a human body in the source image, calculating a depth of the human body in the source image. From the source image, a major radius size and a minor radius size of an ellipse corresponding to a human head at the depth is calculated, and, for at least several of a set of pixels of the detected contour, generating in an accumulator array at least one segment of an ellipse centered on the position of the contour pixel and having the major and minor radius sizes. Positions of local intensity maxima in the accumulator array are selected as corresponding to positions of the human head candidates in the source image.

摘要： 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.
摘要翻译：每个彩色图像被分解成不同原色的至少三个连续的主要图像的至少一系列，其通过调制成像装置的像素的激活持续时间来连续显示。根据本发明，三个连续子帧中的像素激活阶段的分布收缩：第一主图像的像素激活周期朝向该第一图像的子帧的结尾偏移，并且在第三个子帧的子帧期间原始图像，该第三主图像的像素激活周期朝向该第三图像的子帧的开头移动。因此有利地减少了颜色分解故障。

摘要： 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.

摘要： The present invention relates to a method for stabilising a series of measurements of a physical variable captured by a digital sensor. This method comprises the steps of: capturing at least a first measurement, a second measurement, and a third measurement of said physical variable and storing each measurement in a digital memory. The first and second measurements are compared and, if a difference between the first measurement and the second measurement is below a predetermined threshold, the second measurement is replaced in the memory by a corrected second measurement where the difference with respect to said first measurement has been reduced using a first filtering strength. The corrected second measurement and the third measurement are compared and, if a difference between the filtered value of the corrected second measurement and said third measurement is also below the threshold, said the third measurement is replaced by a corrected third measurement where a difference with respect to said corrected second measurement has been reduced using a second filtering strength that is lower than the first filtering strength. This method has the advantage of filtering noise whilst still allowing slow but relevant variations in the series of measurements.

摘要： A sequential illumination system for a visual display unit has a light source emitting a polychromatic light beam towards the visual display unit within a wavelength range having at least three primary colors, and a color wheel provided with at least three transmissive or reflective segments for transmitting the light beam along an optical path in such a way that they successively cut the direction of propagation of the beam. The colour segments are distributed on the wheel in such an order that the differences of energies perceived by the visual organ of a standard observer (visual stimuli), are as equivalent as possible during the intersegment transitions, when the segments pass along the optical path of the beam. The illumination system can be used for movie overhead projection devices.

摘要： The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.
